  • 3. KEF Brand Decoding The KEF logo is simplistic with a shiny and bevelled effect. The slightly bevelled effect represents KEF speakers in their organic designs. The slogan “Innovators in Sound” describes KEF’s designing and technologies, all of KEF’s speakers are very unique in design and also from a technological point of view. The slogan shows the company direction and their ethic. However the logo is more square than all of its products, showing they are fitting both sides of designing. KEF’s organic design leads to speakers that are curved and seem to flow naturally, almost like something we would expect to see out in nature. The organic design does not stop at the flowing designs, some of the materials that they use are also organic giving a natural effect. Mahogany is used as a housing for many of its speakers and this says something about KEF, not only are they “Innovators” but they also use high quality expensive materials in their Materials such as Mahogany, Steel and Plastic are used in the products. housings for KEF speakers. The use of the materials can give a certain effect or change a customers view on the product. Mahogany is used to give a natural effect where possibly the design of the speaker does not flow naturally as much as others. Steel and Plastic are used to give a high gloss effect and compliment an already organic and naturally flowing design.
  • 4. KEF Brand Decoding The function of KEF speakers is to provide high quality music. KEF is a top of the range music company that is innovative in design and in new technologies KEF speakers have very high to allow them to meet the prices but also provide very high needs of all consumers. quality. The high price means that KEF speakers will not be available to every target market. The target market for KEF products is upper class people between 25 and 50. £14,000 £150 £90,000KEF has a vast selection of products ranging from floor standingspeakers to motorised ceiling speakers. The large selection ofproducts, series and designs allows KEF products to fit in with anyenvironment.
  • 5. The reference series is world famous and has set the bench mark for high end audio loudspeakers and is legendary for its clarity and precision.Crossover optimises driver KEF’s cabinets are precisionintegration and response engineered and are a work ofaccuracy. This ensures a art themselves, the volume ofnaturalness in the music each unit meets the exactwithout any electromagnetic parameters of its drive unitsinterference from circuit so that they get rid of anyboards because the boards unwanted vibrationsare separate. KEF has a world renowned reputation for producing high end speakers with excellent precision and clarity. KEF’s innovative design have allowed it to lead the market with its organic designs and new technologies that allow it to stand out from the rest.
  • 6. KEF were the first company to use computers in loudspeaker testing and design which lead to them producing the best quality sound sooner than everyone else. This gave them technological supremacy. KEF were able to match pairs of speakers to within half a decibel for near perfect stereo reproduction. KEF were the first to develop acoustic compliance enhancement technology and are also able to produce speakers less than an inch and a half thick.KEF was also the first to release a motorised ceiling KEF’s signature technology, thespeaker and acoustic compliance enhancement Uni-Q point source driver arraytechnology. KEF’s motorised ceiling speaker is uses NASA developed magnetscontrolled via a infra red remote control so that which are ten times morethe speaker can be at the optimum angle, an powerful than conventionalalternative is to have the speaker flush against the materials. This allowed KEF toceiling like a traditional ceiling speaker. engineer a tweeter small enough to mount at the acoustic centre of the bass unit voice coil so they could act as one. KEF’s wireless sound systems constantly adjust their frequency to make sure that there is no interference with the quality of the wireless sound and signal. KEF’s low profile driver was Other wireless sound systems have developed to meet the needs interference from other typical of LED and OLED displays, household appliances such as wireless reducing the depth from routers, mobile phones and 70mm to smaller than 30mm. microwaves. This is why KEF’s wireless KEF has developed these ultra system is innovative. thin drivers without compromising on sound quality and performance.
  • 7. BRIEF AND SITUATIONDesign BriefMy design brief is to design and build a speaker for KEF. The speaker will need to fit with the aesthetics and functions of other KEF products and have to fit with their designs.KEF is an award winning company that builds high end speakers with all the best materials and components so in my design and build I will have to keep this in mind. Thedesigning process of my speaker will involve doing lots of research into KEF and analysing all possible aspects of their speakers. The research that I conduct will go muchdeeper than what is just on the KEF website because I will need to understand exactly how a speaker works and why certain parts of construction require so much attentionto detail. I will looking into specific materials that are used in speakers and analyse which ones are best and why. Aesthetics are always important in designing but they areparticularly important when designing for KEF because they follow a unique organic design path and I will need to make my speaker fit perfectly with this. Therefore thisproject requires top quality designing and construction. KEF’s slogan is ‘Innovators in sound’ which is key in understand how KEF designs their speakers, they do not followother trends or styles they are unique and their speakers stand out from the rest.Design SituationThere are some issues that I will tackle in my design and try to improve on these aspects above what KEF have already done. KEF speakers are not very versatile and are verylarge, I want to make a speaker that can be moved fairly easily but I don’t want to move away from KEF’s high end speaker designs of being large. KEF speakers also onlyreally have one function which is to play music, KEF focuses more on producing the best quality sound above providing extra functions for the user. I want to try and get highquality sound as well as providing an extra function for the user such as an iPod dock.

  • 9. Initial Specifications Here I am going to be analysing KEF and considering things that they commonly use and things that are key to designing for KEF. This is going to allow me to see what I need to do in my designing and things that are key such as materials, functions and aesthetics. I will be using ACCESS FM to break down key aspects of design and construction. CustomerAestheticsFollowing KEF’s previous designs which all follow an organic design path with KEF’s main customers and upper class individuals and business’ in the musicflowing shapes and natural looking materials, I will design a speaker that fits with industry looking for a quality speaker. Speakers are designed to meet specificthis. The speaker will be large with no sharp edges or points and feature curves needs for certain purposes so their truly is a KEF speaker for everyone. I am goingthroughout its design. to design and build a speaker that could be used for an individual instead of a larger market of business’ in the music industry.CostThe cost of the product depends on the range that the speaker is entered into and Environmentthe materials and technology used in it. KEF’s high quality innovations andtechnologies increase price rapidly along with their high quality and expensive KEF speakers are commonly in household, business or studio environments.materials. However KEF’s smaller ‘Bookshelf’ speakers and the smaller speakers in Because KEF builds speakers to suit all of these environments there is a lot oftheir expensive ranges are lower priced to meet needs and suit an entire market. I room to change and tweak designs and still fit in with KEF although I am designingwill try and follow them in using high quality materials and components to ensure a speaker mainly for use in a home environment.my speaker truly fits with KEF.

This is going to allow me to see what I need to do in my designing and things that are key such as materials, functions and aesthetics. I will be using ACCESS FM to break down key aspects of design and construction.Safety FunctionSafety will play a part in design but shouldn’t be a major issue because using the KEF speakers previously have not served any other functions than to play music.organic designs their will be no sharp edges or corners. The product will be used With the expanding market of speakers featuring iPod and iPhone docks I amin a home environment where there may be children so it must be stable and going to incorporate this into my design to bring KEF into the market so that theywiring should not come lose. All of the components should also be securely joined can get a larger customer base.together so that they do not come lose over time.Size MaterialsHigh end KEF speakers are very large and this allows then to create better sound All of the speakers produced by KEF feature the highest quality materials. KEFquality and also stand out in their environment. Commonly their speakers get does not have a large range of different materials used to construct its speakers,smaller depending on series, application and lower price ranges. I am going to be the main materials used are stainless steel, plastic and wood. The cabinet insidedesigning a floor standing or bookshelf speaker that should fit into the middle KEF speakers is plastic, this allows easy construction and tight fits so there will beprice range of KEF speakers, this means that the speaker will need to be fairly no vibration. I am going to focus on using these materials and use plastic as thelarge but not too big that it cant fit comfortably onto a desk or shelf. inside cabinet for the speaker.
  • 11. Audio Product DecodingIn this section I will be naming the components inside of many types of speakers and alsoexplaining what they in do in getting the product to function. I will be looking into how differentsounds are produced and how the drivers inside of speakers vary to produce the differentfrequencies and different sounds. When the electrical current flowing through the voice coil changes direction, the coils polar orientation reverses. The voice coil is a basic electromagnet, an electromagnet is a coil of wire, usually wrapped around a piece of magnetic metal often iron. Running electrical current through the wire creates a magnetic field around the coil, making the metal it is wrapped around magnetic. The field has polar orientation and has a ‘North’ and a ‘South’ end. But unlike a permanent magnet, in an electromagnet you can alter the orientation of the poles. If you reverse the flow of the current, the north and south ends of the electromagnet switch. This is exactly what a stereo signal does, it constantly changes the direction of the flow of electricity. The amplifier is constantly switching the electrical signal and therefore changing the north and south poles. The alternation in the current causes the flow of current to change direction many times in a second. When the electrical current changes direction it causes the coil magnet to move up and down with the change in magnet fields, the coil moves over the permanent magnet with the repulsion or attraction and causes the diaphragm to vibrate and cause sound waves. Different driver sizes are used in different sized speakers and frequency. Headphones and earphones typically work in the same way as loudspeakers but on a much smaller scale.
  • 12. Audio Product Decoding Driver Types A stereo speaker has both a woofer or a midrange and tweeters. This enables the one speaker to have the same quality music as larger speakers in the size of only one woofer. There Midrange drivers are used to are two tweeters placed over the create a range of frequencies in woofer, there are two tweeters the middle of the sound because this helps to create spectrum. stereophonic sound. Stereophonic sound is more like natural sound and comes from two or more audio channels, this is the opposite to monophonic sound which is sound from only one audio channel and is not likeWoofer’s are the largest drivers used natural sound.to create the lowest frequency Tweeter’s are much smaller andsounds. used to create high frequency sounds.
  • 13. CUSTOMERKEF has a large customer base, however they are in a competitivemarket amongst other high end speaker companies suck and Bowersand Wilkins. KEF produces a large variety of ranges of speakers thatvary both in price and size, however quality barely changes withintheir speakers. The large variety of applications, price ranges andenvironments for their speakers means that they can attract a verylarge market stretching through not only the professional market butalso the commercial market. Speakers such as the Muon aredeveloped for the top quality sound and aesthetics, priced at nearly£100,000 they are aimed mainly at the professional market, thisbeing studios and music producers. Speakers such as the Referenceseries are produced to attract both professional music producers andalso individuals for a passion for music. Prices in this series rangefrom £14,000 to £4,000, showing that this range alone is aimed atprofessionals and individuals with a large market.KEF not only attracts its markets with pricing but also because theyoffer such a large variety of applications ranging from Home theatresystems to in wall speakers and outdoor speakers. Again this isbuilding on KEF’s customer base and increasing the size of theirmarket and enabling them to compete effectively with other largebrands.
  • 14. LINKS FX In this section I will be looking at certain factors in the process of designing and analysing what I will be doing. I will be using LINKS FX which will help me to analyse what I should keep and scrap and also what the uses are for a speaker. Analysing these factors is going to bring me closer towards generating ideas that are logical and useful for the customer.Logical NeedThe speaker must designed with the needs of the consumer in mind, designing for The speakers are going to need either stereo speakers or a separate amplifier,KEF makes this easier to do because of their wide customer base gives more room tweeter and a bass driver. The speaker will need to have a case and frame that isfor different ideas and applications. The most logical use for a speaker is to be securely built to have as little vibration as possible, creating the best possibleable to stand alone and play music. Vibrations in the speaker must be minimal to sound. The speakers will need a power source that can power the speakersgive the highest quality sound. effectively. The case of the speakers must be stable so that it can stand on a shelf or desk without falling over.Illogical KeepIllogical uses for speakers depend highly upon the application and function of thespeaker. I am planning on designing a bookshelf speaker that will be fairly large so I am going to keep the plastic frame inside of my casing to house the speakers andan illogical use for this will be to pick it up and carry it around. However an also help minimise vibration. I am also going to keep using the materials that KEFillogical use for a pair of headphones is to leave them on a surface and play the almost always uses in its speaker casings, wood, metal or plastic. I am going tomusic out loud. Another illogical use for the speaker I will be designing is to put it create passive speakers which fits with most other speakers on the market and Ioutside. Illogical uses for a speaker are things that people might do with the am also going to keep the design of keeping the drivers and tweeters separatespeaker that it is not designed to do. and not using a stereo speaker.
  • 15. LINKS FX In this section I will be looking at certain factors in the process of designing and analysing what I will be doing. I will be using LINKS FX which will help me to analyse what I should keep and scrap and also what the uses are for a speaker. Analysing these factors is going to bring me closer towards generating ideas that are logical and useful for the customer.Scrap X - FactorI am going to scrap the traditional ‘Block’ speaker design and follow a natural The X-Factor is the aspect of the speaker that makes it different and stand outorganic design path, taking inspiration from previous KEF speakers such as the from all the other speakers on the market. Because of KEF’s organic designs itBlade or the Reference series model 207/2. designs are more aesthetically means that every speaker they design and produce is unique so producing anpleasing when they make the customer think of natural materials and shapes. aesthetically unique speaker will be fairly easy. However creating a speaker with an X-Factor in terms of its functions will be difficult because most modern speakers have an iPod dock, due to this its not the actual function that is going to be unique it’s the way in which the function is set into the speaker and used byForm VS Function the customer.KEF is a company not to compromise on either its form or function, to upholdtheir quality standard and continue being ‘Innovators in sound’ they mustproduce both excellent design and excellent function. Trying to carry on the KEFstandard will require lots of designs and use of ACCESS FM to analyse separatedesigns to consider all aspects and what will work best together. I am going toconsider adding extra functions than previous KEF designs such as an iPod dock,however I must incorporate it into my design in a way that doesn’t compromiseon aesthetics or the organic design.

  • 18. Research PlanEnvironmental Snapshot Access FM of secondary productsI am going to take photographs of Using ACCESS FM I will look at other speakers from throughout the market. This can be used to aid me in doing my competitivespeakers in their usual locations that KEF’s companies research, however I will not only be analysing competitive speakers to KEF in this section I will be looking at speakerstarget customer would most likely have the that range in design, quality and applications to get a wider knowledge of how speakers are built and designed to attract a certainspeaker placed. I can then use these audience. Ranging the speakers that I look at will let me see the best way to overcome any possible problems that may arise andphotos to help me design a speaker that is also let me see what works best in every aspect of design and construction. The advantages of doing this are that I will gain agoing to fit nicely into the location and greater understanding of speakers throughout the market and this will enable me to design my speaker to be the best it possiblyprovide possible functions that may be can. The disadvantage of doing this is that some of the speakers that I look at will not be the same as what I am looking to designuseful here. It will also help me see what so the information will not help me that much.other products are next to or surroundingthe speaker and give me a greaterunderstanding of certain materials that may First Hand Existing Design Analysisappeal to the customer or help the speaker Questionnaire First hand existing design analysis involves going out to shops andto fit the location. My questionnaire is a set of eight questions that I will looking at other speakers from KEF and competing brands. I will be ask to a variety of people, this is going to help me gain taking pictures of existing speakers and then analysing them using a first hand view of my target market. The questions are ACCESS FM, I will then be able to compare the speakers to each otherPerson and Product Interaction multiple choice so that it will be easier to segment the and see what aspects from different speakers are good and which don’tI will analyse certain types of speaker to see how answers and understand the market better. I will ask work very well. The speakers that I look at will be mainly of the samepeople interact with them, I will then use the information each of my questions to 10 people and all of the people application, this being the one I am planning to design, this is going toI collect to see whether there is a relation between the will be different for each question. The advantage of help me in my designing to see how this speaker application is built anddesign and style of the speaker and the way people doing this is that I can get a better understanding first used. This is very similar to ACCESS FM of secondary products,interact with it. This is going to help me see how hand of the market and have the opportunity to discuss however in this section it involves going and seeing the speakers firstdifferent speaker applications or types are used and talk to the market. The disadvantage of doing this is hand. This allows me to make a clearer judgement of the speakers anddifferently by the customer and why, linking this with my that I am not choosing a specific group to question and allows me to analyse them in greater depth with more knowledge aboutenvironmental snapshot will help me to see where therefore some of the people that I ask questions to will each of them. Doing this first hand means that I can see the quality ofdifferent speaker types are used and what their normal not be in my target market and their answers will not be the speaker and also analyse the designs better than having to do itlocation is. This is going to help me in my designing so relevant to me. from a picture in my secondary research.that I have more design ideas that will all appeal tocustomers.

After looking into the target market of the different Brand profiling does not involve using ACCES FM to look for KEF speakers and my speaker. I am profiling them in allspeaker brands I will be able to see how different audiences like to at any other speakers, it just involves researching deeper aspects such as age, gender, income, disposable income andinteract with their speakers, I can then incorporate these into my into KEF.

  • 21. Person and Product InteractionFor part of my research I have looked at different ways that people interact and usespeakers. I have noticed that the functions of the speaker affect that way that a customeruses it, for example speakers that have an iPod dock need to be interacted with differentlyto those that do not. This section of my research has enabled me to understand how When the speaker incorporates an iPod or MP3 input, thecustomers will use my speaker, I have been able to understand how the functions of my user needs to interact with the speaker by plugging thespeaker mean that the usability needs to be considered more so that the user can access device into a port. Being a desk speaker I am going to placeand use the functions with ease. buttons or dials by the input so that the volume can be adjusted easily and quickly. The usability of my speaker is an essential part of the design, I need to ensure that the user can access and use all functions of the speaker easily. I have noticed that speakers that use a remote control are much easier to use than those that do not. This is especially the case when the speaker has functions such as MP3 inputs and capability. The remote control allows the user to switch between input modes easily and also adjust the volume without having to physically interact with the MP3 device. Remote controls are not generally used with speakers that do not have extra added functions, this is because there is usually a remote control for the device that the speaker is connected to. Because my speaker is an independent speaker that will be able to have an MP3 I have noticed that portable speakers are used more vigorously than any other type of input, I have considered using one. speaker. I am designing a bookshelf speaker and am going to design the speaker so that it is However, I have decided against it because larger than the average bookshelf speaker. This is because I want to cross the line between my speaker will be a desk sized speaker and ‘Portable’ and ‘Bookshelf’ by quite a way. This is because my speaker is not designed to cope therefore the user will be close to the with the stresses and strains of being treated in the way the portable speakers are. Portable speaker to control it. speakers are often thrown or dropped into bags or suitcases. From the people I have spoken to and observed I noticed that all of them treated larger speakers more carefully than smaller ones.
  • 22. Environmental Snapshot These are different rooms that I am planning to design my speaker to fit into and compliment. All the rooms are similar in design and all feature mostly plain colours such as white and black but also have one or two colours that stand out from the environment. They feature materials such as wood and stainless steel, which are two of the materials I have considered amongst a range of others to use in my design. The speaker I am designing will have mostly plain looking colours, but not boring, because they will be made of high quality materials that will be finished to help the speaker compliment its surrounding furniture. I will have one or two areas on my speaker that will have a bright colour, this is going to follow the contemporary path and mean that the speaker can be used in any contemporary room as a feature as well as just a speaker. I am going to follow an organic design path of flowing shapes as well and a contemporary colour scheme. This is going to make my speaker appeal to a wider audience and suit a wider variety of environments.
  • 23. First Hand Existing Design Analysis These are pictures that I have taken of speakers from KEF and their competitive companies. By being able to view the speakers first hand it has enabled me to see the quality of the speakers both in materials and in sound quality. I had the opportunity to listen to some of the speakers which helped me to realise the extent to which KEF go to, to make their speakers the best they possibly can. I had already noted the main materials that KEF uses in its speakers and was planning to use these in my design, and this has been backed up by seeing the materials in use first hand, it has enabled me see how each material works well and what materials I should research into in more depth for my speaker. KEF had small displays to show off their materials in greater depth and why their materials are of such high quality. I had managed to see other braded speakers such as B&W and Meridian. I have been able to compare different speakers and be able to see why they are priced differently. It has also enabled me to see how different design styles are used and how different materials are used to compliment these styles. I have also been able to see different applications of speakers and how these are designed differently and the functions that they include.

Because I am not using all of the inputs in my speaker I will not be using a circuit board. The wiring from the circuit board to the speakers is very simple. Two wires go to each speaker, this shows me that without the circuit board and all of the input methods the wiring will be simple to do. From research I have done online I have seen that in many cases an input source is connected to one speaker and then that speaker is connected to the other. I will research further into understanding which method will be best for me.This speaker is powered by a small lithiumbattery that is similar to one used in a mobilephone.

  • 28. BRAND PROFILINGHere I am profiling the KEF brand, I am showing a list of applications thatKEF produces to achieve its wide customer base. I am showing the This is one of KEF’s newestprogression of KEF’s speakers below from the 1960’s up to 2000. KEF has speakers, the ‘Blade’. Thisprogressed in all areas from aesthetics to technological advances. When KEF shows the clearwere founded in 1961 they were producing only simple speakers, both in advancements over timesound quality and aesthetics. KEF has grown to become a world renowned and also in the ten yearsspeaker company that has a very good reputation for producing high quality from 2000 up to 2012speakers. KEF’s advancements were fast and Raymond Cooke had decidedto use only the newest and high quality materials in the production of itsspeakers.
  • 29. BRAND PROFILINGTechnologies KEF’s technologies have been the thing that have excelled KEF above the rest. KEF has set its own objective to be ‘Innovators in Sound’ and it is evident from viewing the amount of new technologies they have to see that this is being achieved. All of KEF’s technologies are designed to provide a better experience for the user in every way possible. KEF’s Uni-Q drivers, SST and Single apparent source are just a few of the technologies that KEF has to improve the listening experience of the user. KEF also has technologies to make their speakers easier to use, a few of these are the Selecta Mount, Wireless, and the Bass Extender. KEF offers huge advances to its customers and in return they earn an excellent reputation and a loyal customer base. It is this that pushes KEF to make these advancements and in some cases lead the market.
  • 30. BRAND PROFILINGKEF is a multi award winning company that has won 92 awards from around the world. KEFwon its first award in 2006 in the UK for ‘Best Product’ which was for the HT Loudspeaker.Almost all of KEF speakers have won an award ranging from Product of the year to BBCmusic choice awards. The awards that KEF have won have pushed them to createincreasingly unique technology that improves speaker life times and performance and thelistening experience of the customer.
  • 31. Price I have organised a selection of speakers in terms of price and function. This has HighProduct Profiling shown me that an increase in price does not mean an increase in functionality. An increase in price usually leads to an increase in build and sound quality. I have included speakers not only from KEF but other brands across the market, this has enabled me to gain a greater insight into the market opposed to what only KEF does.Functions - Few Functions - Many Price Low
  • 32. Customer Profiling The customer profiling is where I am profiling the target customer for KEF speakers and my speaker. I am profiling them in all aspects such as age, gender, income, disposable income and other belongings. This is going to help me in the design of my speaker because I will be able to see al l the information about my target customer that is relevant to my design. I will be able to see what materials they like, their age, gender and whether they own lots of expensive items. All of these will help me decide on the production of my speaker and what materials and components I will use. I will also be able to make sure that they like organic designs and try to make my speaker fit with things they may already have. My users will range from people wearing branded clothing that’s expensive to people that are not bothered by brands and will buy any clothing. The income of the customer will range from high to low, this is because KEF speakers range in price from around £150 to £14,000. The market for the speakers will be upper or middle class business men and women, they will be expecting high quality materials and components throughout the product. The market is also filled with professional music producers or beginners who want to start their own studios, they will be expecting an aesthetically pleasing speaker that has great sound quality and a long life time.
  • 33. Mood Board As you can see from my mood board I have taken inspiration from lots of different types of speaker and lots of different designs. The speakers I have taken inspiration from all have organic designs which is how I am going to design my speaker. The materials used in these speakers are the materials that I plan to use in my designs and then I will pick one or two to build my speaker from. All the speakers that have inspired me to consider my designs stand out from their environments, instead of an eye sore they are placed as if they are a piece of art, this is how I want my speaker to be placed and used in its environment. Most of the speakers that have inspired me are bookshelf speakers which is the size I am planning to build my speaker, however the designs and shapes of the larger speakers have inspired me to think about how these designs can be adapted to suit a smaller speaker. I have also looked at speakers with an iPod dock, although KEF’s bookshelf speakers do not have any other functions I am planning on incorporating this into my design.

The dotted paper I haveused adds a sort of scale to the designs and can represent sizes of differentaspects of the design in relation to others. All designs are annotated to showthe different parts and to briefly describe the design behind the speaker.
  • 39. Initial Sketches Again on this pages I have a page consisting of four different designs that have all been annotated. The graph paper has been used to show a scale of the design, as well as this it also makes the page stand out from the others that have many designs on. The blue paper has been used to ensure that the pencil stands out from the paper without the need of a pen. Most of the designs are shown from more than one angle, the ones that are not are the ones that are understandable from one 3D drawing.

Thedotted paper has been used to use a certainpoint to draw some designs in 3D in greaterdetail that free hand drawing. It has allowedme to show my designs in 3D from specificangles. The squared paper has been used sothat I can sketch my design easily and moreaccurately according to the lines.

On one pages the sketches are rough and colour has been used to represent different materials. The second page has sketches that are draw neater and a pen has been used to go over the edges and make the sketches stand out from the paper. I have used a pencil to shade in certain areas of the speaker and show a simple diversity in colour. All the designs are annotated and most are draw from multiple angles to show the speakers sizes and shapes ate different view points.

Here I have considered two different things. I have thought about making the speaker housing into a more thin curve. This would help the speaker to keep with the thin design of the speaker. I have also considered being able to tilt the speakers backwards, this again will enable the speaker to direct sound and make it moreMy speaker is going to have both a woofer and a tweeter. This is going to spread out. However this would be difficult toenable my speaker to reach high and low frequency sounds. Woofers are do because of the swivel of the speakers. Itbigger than tweeters and thinking about this I have decided that my would make manufacturing much harder andspeaker housings will be two different sizes to show the different may also lead to the speakers not staying in thespeakers. This also helps the speaker to look more organic by making it desired position. Again I would look at theless symmetrical. mechanism in a tripod to see if it would be compatible to do this on my speaker.
  • 44. Design Development This 3D design shows the base that I have chosen from my sketches. The base is more organic than my original design and also will be easier to mould. Here I have considered different designs for the base of the speaker. The 3D design shows my original idea for the base, however I have sketched four different bases of which I will choose one to use. All of the base are using organic design, which shows that I constantly considering my initial specifications. Here I have thought about a range of materials that I could use for the base. I have thought about the properties of each material and used this informationWood wouldn’t be Although aluminium HIP’s is easy to mould to help me make a decision. I have decided to usesuitable for the base would be easy to shape and comes in a variety HIP’s which is a material with a high strength to weightbecause it is not easy and create a hollow of colours.

  • 45. Design Development Heater Because I am using HIP’s for the base of my speaker I am going to vacuum form the material into the shape that I want. Vacuum forming requires a wooden mould to be made of the shape that you want, which is then clamped HIP’s sheet into place above the mould and heated. The mould is then lifted into the softened plastic and the air is sucked out. Vacuum forming can give small details and is very accurate. Lever to lift mould into soften polymer Vacuum switch To join the acrylic to the base I have considered two different methods. I looked at both araldite and self tapping screws. I have listed the advantages and disadvantages of The bottom of the speaker will be an each and have decided to use self oval of acrylic attached to the tapping screws. This is because it bottom of the vacuum formed provides a very strong hold and is mould. I will place the vacuum not permanent which means that formed mould onto the sheet and the base can be removed to repair draw around it as a template, this wires if it is needed. Self tapping will mean that the oval that is cut screws also come in a variety of from the acrylic will fit perfectly sizes to suit any use. onto the bottom of the HIP’s mould. I will use the hegner saw to cut the oval from the acrylic. This will give a fast and accurate cut. I will need to use wet and dry on the edges are cutting to make sure that they are smooth.
  • 46. However, I have now decided I will use theDesign Development hegner saw to cut the slot for the iPod dock. I will use the hegner saw because it is quicker and gives a better cut than a hack saw. The base of the hegner saw can also be tilted to give a 100% accurate cut, this is also due to the very thin blade on the hegner saw which can give finer detail than say the band saw.I have also decided to incorporate an iPod dock intomy speaker base, this is going to improve thefunctionality of the speaker. I also considered using ahack saw to cut the hole for the dock to fit into. I have also sketched out four possible designs for the branches of my speaker. All of which use organic design and will hold two speakers. The material I will use Here I considered the function of being able to for my branches will be steel. I swivel the speakers together so that they become a am going to use steel because it sphere. However I have found faults with this idea. is a very strong material that can The speakers would not be able to swivel together be bent into the shape that I without the branches being able to be push closer want using a bending jig.

This is because one very shiny finish which is what I highlighted in green is the one speaker will be higher than the other and also one is want for my branches. that I have chosen to be my final smaller than the other. branch design. The design isn’t symmetrical like my original design and is more organically designed. I have however reversed the design and made the left pole shorter than the right.
  • 47. Development Checkpoint 1 All of the changes that I have made to the aesthetics of my speaker make it fit into the organic design path even more. I have changed my speaker from being symmetrical to beAesthetics asymmetrical, which is a more organic approach because itFollowing KEF’s previous designs which all follow an organic design path with represents the uncertainty offlowing shapes and natural looking materials, I will design a speaker that fits with natural objects. All of thethis. The speaker will have no sharp edges or points and feature curves different designs that I havethroughout its design. considered have all been organic so I have constantly been considering different shapes, they also all feature flowing shapes with no sharp edges. The changes and designs I have done all fit with my initial specification.CostThe cost of the product depends on the range that thespeaker is entered into and the materials and technology used In the first section of myin it. KEF’s high quality innovations and technologies increase development I have coveredprice rapidly along with their high quality and expensive materials that will be used inmaterials.

I will try and follow materials used by KEF andthem in using high quality materials and components to decided on HIP’s which fits withensure my speaker truly fits with KEF. my initial specification of using high quality materials.
  • 48. Development Checkpoint 1 I have gone further than only considering the functions that I listed in my initial specification and also considered ways in which the easeFunction of use could be improved for the user and also ways in which theKEF speakers previously have not served any other functions than to play music. speaker could be more useful. IWith the expanding market of speakers featuring iPod and iPhone docks I am have incorporated an iPod dock intogoing to incorporate this into my design to bring KEF into the market so that they my design which I listed in mycan get a larger customer base. specification and have also decided to use the function of being able to twist the speakers so that they can point in different directions. I have decided not to use the other functions I considered because it wouldnt fit right with the speaker design and would complicate the usability.SafetySafety will play a part in design but shouldn’t be a major issue because using the Even throughout myorganic designs their will be no sharp edges or corners. The product will be used changes I have beenin a home environment where there may be children so it must be stable and considering the safety of thewiring should not come lose. speaker. There will be no edges that could harm the user as all of the components for my speaker do not have sharp edges. I will be considering the safety through the rest of my development process. I have followed this from my initial specification.
  • 49. Development Checkpoint 1MaterialsAll of the speakers produced by KEF feature the highest quality materials. KEFdoes not have a large range of different materials used to construct itsspeakers, the main materials used are stainless steel, plastic and wood. Thecabinet inside KEF speakers is plastic, this allows easy construction and tight fits sothere will be no vibration. I am going to focus on using these materials and useplastic as the inside cabinet for the speaker. I have decided to use HIP’s for the base of my speaker and also for the speaker housing. The use of plastic for the speaker housing will reduce vibrations and therefore improve sound quality and it is also what KEF use for the cabinets inside of their speakers. The branches of my speaker will be made of stainless steel or aluminium which again is one of the three main materials used by KEF. The only material that I will not be using in my design that is used by KEF is wood, however, I have considered using it. I will develop and consider the materials more throughout the rest of my development.
  • 50. Design Development I have considered three different materials for my bending jig and these are wood, metal and plastic. I have I have decided to create a bending jig chosen to use wood without having to that I will use to bend my poles research into the materials properties around. This not only makes the further. This is because I know that process quicker and easier for wood is easy to mould and is strong bending them it also means that I and is also easy to adjust very slightly. could bend the poles over and over These are the properties that have again to the same angle every time. made me choose wood over metal or plastic. My jig will be made by cutting the corners off of an MDF block to form the basic oval shape. I will then use the belt sander, sand paper and files to finish the edges and get them to the exact angle that I want. I will then use the first finished oval to create other ovals. I will do this by using it as a template and drawing around it and cutting out the other ovals. The ovals will then be glued together using PVA to create a firm hold. The ovals will be need to be finished once the glue has dried to ensure that the edges are smooth and flat.
  • 51. Design Development My original thoughts for the branches were that I would use solid poles to add strength to my design. I have however now decided to use hollow poles which will be much easier and more practical than using solid poles. Using hollow poles allows the wires to be easily thread through the poles because trying to drill a hole all the way through solid poles would have been impossible. It also will make the poles easier to bend around my jig. It will also bring the weight of the speaker down and mean that the speaker will be more stable.My original design of joining the speaker housing to the brancheswas to use the lathe and make one end of the poles thinner so thatit could be put through a hole on the bottom of the speakerhousing. I would also have threaded the top so that it could bebolted on the inside of the speaker housing. However, this is notpossible when using hollow poles. Joining this way enables the Because the poles are now hollow I am going to insert a threaded piece of metal intofunction of being able to swivel the speakers. the end of the hollow pole. This will still mean that it is thinner than the pole and so can have the speaker housing rest on it. I will use the pillar drill to drill a hole though the insert so that wires can still be threaded through the poles.
  • 52. Design Development I have thought about the way that the speaker will sit on top of the pole and have realised that the pole may stick out at the front slightly. I have no decided to have a small flat area that will enable the speaker to sit flat on the pole without causing the pole to protrude at the front. I have considered three different materials for the housing of the speaker. These materials are HIP’s, aluminium and wood. I have listed the strengths and weaknesses of each material below. I have decided to use HIP’s because it is self coloured and is the easiest of the materials to form into the bowl shape that I want. It is also a strong material and has a shiny finish without the need to finish and polish.I have decided that the easiest way to form the hollow bowl shape that I need fromHIP’s would be to vacuum form it over a wooden mould. Vacuum forming is a veryquick process and is easy to do. It can also get very fine details, although I do notneed any fine details for my design. The mould for my vacuum forming will be made from MDF. This is a man made board that is easy to shape. I will need to glue sheets of MDF together using PVA to get the height that I need for my bowl.
  • 53. Design Development The vacuum forming process involves heating the HIP sheet and then lifting the wooden mould into the softened polymer. A vacuum is then used to remove all of the air around the mould, this causes that plastic to take the shape of the mould. To help secure the speakers into the bowls I have decided to use a small acrylic ring that will be secured inside of the bowl. This ring will give the speaker something else to attach to and make it more securely attached.I have decided to use acrylic to make the ringbecause it is a strong material and can belaser cut, this is a CNC machine which givesextremely accurate cuts using a laser. This willmean that my ring will be the exact size that Ineed it. I have considered both screws and araldite to secure in the ring however, I am going to use araldite to secure my ring into the bowl. I am using araldite because it is very easy to apply and doesn’t require a lot to get the full strength hold. Araldite creates an extremely strong hold which joins plastics by creating another layer of plastic between the two plastics.
  • 54. Design Development I have thought about two different materials that I could use for this ring, these are acrylic and aluminium. Both materials would suit my speaker but I have decided to use acrylic. This is because it is easier to shape accurately and also easier to join. The acrylic will also help make the speaker seem like it is one piece with the bowl because it is self coloured.I have also decided to have another ring that will be placed around the outside of thespeaker once it has been secured into the bowl. This ring is going to hide any evidenceof joining and also make the speaker seem more like it is one piece with the bowl it issecured into. The ring will also make the speaker more securely joined with the bowl. I will use araldite to secure the ring because it is the strongest way of joining two plastic without having to damage the plastics or waste material in some way. Araldite also dries clear which will mean that the joining of this ring will be invisible.
  • 55. Development Checkpoint 2 In the second part of my development aesthetics has been a minor changeable area and therefore has minimal change. TheAesthetics changes show that the speaker follows my initial specifications by having flowing shapesFollowing KEF’s previous designs which all follow an organic design path with and no sharp edges. The only change that Iflowing shapes and natural looking materials, I will design a speaker that fits with have made to keep with this in the second partthis. The speaker will be large with no sharp edges or points and feature curves of my development is that change regardingthroughout its design. the way that the speaker sits on the top the poles. I realised that the pole would protrude from the front of the speaker slightly and be a sharp edge. So I changed this so that the bowl has a small flat area for the pole to join onto, This removes the sharp edge.Cost Materials and processes have beenThe cost of the product depends on the range that the speaker is entered into and developed further in the second part ofthe materials and technology used in it. KEF’s high quality innovations and my development. The materials I amtechnologies increase price rapidly along with their high quality and expensive using have all been thought about andmaterials.

The processes I am going to use to shape and form the materials are not expensive processes and are quick and easy to do.
  • 56. Development Checkpoint 2 The safety aspects that I have considered in the second part of my development have been to do with the way in which the components of the speaker are joined together. I have developed areas such as the way inSafety which the speaker will attach to the bowl to ensure that the speaker is held in securely by two rings. The ringsSafety will play a part in design but shouldn’t be a major issue because using the however are not only for extra safety they are also thereorganic designs their will be no sharp edges or corners. The product will be used to add aesthetic appeal to the design.

All of the components should also be securely joined aesthetics like on so many products today, but theytogether so that they do not come lose over time. compliment the aesthetics. I have also developed the way in which the speaker housing is attached to the poles, not only to make sure they are securely attached but to enable other functions that I have developed.MaterialsAll of the speakers produced by KEF feature the highest quality materials. KEFdoes not have a large range of different materials used to construct its The materials I am considering for all areas ofspeakers, the main materials used are stainless steel, plastic and wood. The my speaker are the three main materials that Icabinet inside KEF speakers is plastic, this allows easy construction and tight fits so listed in my initial specifications. This isthere will be no vibration. I am going to focus on using these materials and use because I want my speaker to fit with KEF asplastic as the inside cabinet for the speaker. much as possible. The casing for my speakers is plastic which I also said in my initial specifications that I would do because KEF do this and also because it stops any vibrations which would interfere with the sound. I am using two of the three main materials in my speaker, these being plastic and steel.
  • 57. Design Development Because I am now using two I have developed and tested different ways different sized speaker I have that the two poles can be joined together decided I am going to use a and have decided to join them in the way woofer and a tweeter. This is that I have shown below. The shorter pole going to enable my speaker to will be filed so that it has an indent that reach high and low frequency can fit around the longer pole and be sounds as well as being joined. asymmetrical which is an organic style of design.I will be using the brazing process to join the twometals together. Brazing is a much neater process thanwelding and uses a very thin flame to melt brass whichwill join two metals together. The thin flame makes theprocess more accurate than welding and is also one ofthe neatest ways of joining two metals. I am trying toachieve a look that makes the two poles seem like onecontinuous metal, this is why I have chosen brazingover other methods such as welding. After filing the pole inwards the outside edges of the indent will need to be filed so that they can be filled with brass that will then be melted to secure the two poles together. This indent means that the brazing will not cause a bump on the metal like welding often does but will join the metals so they look like one continuous metal.
  • 58. Design Development To enable all of the wires to thread through the poles I will need to drill a hole into the longer pole under the joint of the smaller pole. This allows all wires to thread to all speakers from the base. I After all of the filing has been done I will fill the will drill this hole using gap with brass which I will then heat using an the pillar drill to ensure oxy acetylene torch. This will cause the brass to that the hole is drilled as melt and fill this gap and join the two metals neatly as possible and in together permanently. exactly the right position.I have decided to add controlbuttons for the iPod dock ontothe base of my speaker. I haveconsidered two differentmaterials for the buttonswhich are plastic and rubber. I have decided to use rubberbecause it gives more grip for the user. The best place for thebuttons to be is on the base because the speaker is abookshelf and desk speaker so the base is the ideal height foreasy access to the buttons. The holes for the buttons will be marked with a pen to ensure that the hole is cut in the correct position and at the right size. I will use a hand drill to drill four small holes, one in each corner of the marking. I will then use the hegner saw to cut the hole out between the holes. The hegner saw is the best machine to use because it has the thinnest blade that can be removed and put through the first hole. It is also very quick and accurate.
  • 59. Design Development I will secure the base to the poles in the same way that I am securing the speaker housing to the poles. I hole will be drilled in the top of the base for the pole to insert into. Self adhesive cable clips will be used to secure the wires inside of the base. This ensures that the wires will not come lose and also that the user does not have to deal with lots of wires. The only wire that will come out from the speaker base is the three pin power cable.The pole will need to have the same threaded insert at the bottom aswell as at the top. This is going to allow the pole to set on the base andbe bolted on the inside. I will also use an epoxy resin on the inside ofthe base to secure the pole so that it cannot be turned or swivelled likethe speakers.

The cable clips are not a permanent hold and can be loosened so that wires can be moved or repaired if needed. I have also developed the way in which the two poles will be joined together. This is possibly the most important joint in the whole speaker because if this fails the speaker will break and it will also damage surrounding objects so I had to consider many different methods of joining this but have decided on brazing because it gives a strong hold and also the neatest finish.MaterialsAll of the speakers produced by KEF feature the highest quality materials.

  • 62. Final Design
  • 63. Final DesignHere I have placed 3D models of my final design into differentenvironments similar to the environment in which my speaker has beendesigned for. The environments that I have placed my speaker are allcontemporary living rooms, this is because this is where I havedesigned my speaker to be placed and where the speaker wouldcompliment the surrounding furniture most. Although I am usingorganic design within my speaker design, after researching into organicdesign further I have found that it is similar to contemporary design.This is because both styles have flowing curves and rounded shapes.This is why I have decided that my speaker is going to be designedaround other contemporary styles as well as being organic.Contemporary styles use organic materials and usually feature onevibrant colour within a room or object. This is what I am doing in myspeaker by using the blue speaker housings.
