The Company ‘The company was founded in 1961 by Raymond Cooke OBE (1925–1995) and was initially headquartered in a Nissen Hut on the premises of Kent Engineering & Foundry (from where the name KEF is derived) – a metal-working company on the banks of the River Medway, near Maidstone in Kent. Cooke, an ex-BBC Electrical Engineer, was keen to experiment with new materials and technologies in order to create products with superior acoustic quality that could reproduce recordings as natural as the original performance. From the very beginning, the pioneering inventiveness of KEFKEF focuses primarily on the quality of its products. Its products show loudspeakers was undeniable and now for several decades,innovation and include the latest technologies to distinguish themselves audiophiles around the world have revered KEF for itsfrom other companies. I will hope to use these technologies in my audio innovative, high-performance loudspeakers.’product. KEF aims to make their products simplistic in terms of therefunction and colour schemes which I would like to incorporate into my KEF is a company with the primary objective of creatingdesign. The product sold by KEF are top of the range with their target high end, high quality products with vast amounts ofmarkets set to high end purchasers in need of the latest most advance functionality and aesthetical appeal. The Brand has alsoaudio equipment. Although the technology in KEF’s products are far combined innovative design and technologies together toabove other companies the aesthetics in some of the standard speakers solely improve on the performance of its products. Theare lacking in terms of the use of innovative shapes e.g. C Series company has received many awards for its audio systemsspeakers (middle bottom). Although KEF’s simplistic colour schemes especially from their blade loudspeaker which has beenlooks modern they can look too plain however this has been rectified in awarded product of the year in 2012 by electric house as wellKEF’s latest projects such as Blade. as various best buy and highly recommended awards. Through research of the company I have gained knowledge of KEF’s reputation and of what KEF’s aims are. This will help me to design a product that is in keeping with the quality of products currently sold by KEF.

This will help me toexceed these prices. make a product that is suited to KEF’s style.
Technology:KEF has developed new technology which isimproving both the quality and functionality oftheir product making their products unique.The Uni-Q point source drive array gives‘outstanding acoustical clarity and off axisdispersion’. The device helps to spread out thequality of sound so that you do not have to standdirectly in front of the speaker to gain optimumsound quality, the sweet spot is wider. In their flagship Hi-fi speaker blade they have included two set of oppositely facingThis materials is called ACE (Acoustic speakers. A vented coupler system has been included within the speakers to reduce theCompliance Enhancement). The material is a build up of air pressure behind the diaphragm which can damage the speakers and theform of charcoal. It is put inside the loudspeaker sound quality. Also a decupling system has been integrated into the speaker to reduce thecabinet. ACE has small holes in it which act like distortion from the speakers interfering with the diaphragm giving a deeper more dynamicsmall air sacks taking in air helping the bass base tone. The drivers within the speakers create vibration and if unchecked it causes thedriver to ‘breath’ giving improved bass cabinet to resonate creating unwanted sound. To solve the problem the blade speaker hasperformance. its drivers in opposing pairs meaning that the vibrations cancel one another out giving a better sound quality.
Task AnalysisFunction: Multiple speakers could be used for increased sound quality. The portability of thespeakers also needs to be taken into account. The speaker could have iPod/ smart phonedocking capabilities which is becoming ever more popular allowing for more ergonomic control(touch screen on smart phones). Another important focus is what type of speaker it will be e.g.docking station, headphone, Wi-Fi or surround sound. Linked also with functionality is what Through task analysisenvironments the speaker can be put into e.g. outdoors or inside. I have opened up all ofMaterials: the possibilities that IThe materials that can be used need to have good aesthetics. The materials must also be in could use within mykeeping with current KEF products e.g. aluminium and plastics. The materials should be ofhigh quality as the price range of KEF’s products are high. The materials should have design giving me astrength to make the products structure more durable. Also finishes can be added to the wider variety ofmaterial to improve aesthetics and longevity. The materials could be found from far afield for options.more unusual material or sourced locally for a higher quality.Technology: The speakers could incorporate several KEF technology such as ACE orUni- Q to optimise the sound quality of the audio product.Size and environment:Were will the speaker be used? How big will the speaker be? Will the audio product bein the form of headphones or a stereo system? Environment and size are closely linked.For example when designing a bedroom speaker it needs to be of reasonable size toproduce enough sound but not too big to take up too much space.Manufacture: The audio product can be made in several mays. The processes aredependant on the materials being used for example when using metals a forgingmethod will be used however forming will be used for plastics. Mass production, batchproduction and one off production are all manufacturing method that need it be takeninto consideration however KEF often stays with batch production.Energy: The speaker can be powered is many differentways these include: Solar energy, batteries, mains powerand manual power.
Audio product decoding 1 2 3 Within a speaker there is both a permanent and a mobile magnet. The permanent magnet is secured firmly. As an electric current is passed through the coil of the electromagnet its magnetic field is rapidly changed causing it to oscillate between repelling and attracting the permanent magnet. This To produce a fully functional speaker causes the coil to vibrate back various components are needed to and forth. The coil is attached to produce sound.

BriefI am going to make a speaker that has both organicaesthetics and a high quality of sound. The speakerwill have a organic approach and will useinteresting colours and shapes to make my speakerboth innovative and eye-catching to KEF’s high endbuyers. The speaker will be designed for inside useand will be a small multiple cone speaker. Thespeaker will include several speakers with a similarvibration technology as KEF’s blade speaker. Thetarget audience will be high end purchasersinterested in spending more money for a highquality product. The age group of my product will bebroad and appeal to all ages. The speaker will be asmall compact but powerful unit, similar to KEF’sLS50 and will incorporate new technologiesoptimising its performance. From this page I have gained a greater understanding of what the objectives of my speaker are and what I will do to with it to achieve them.

Target MarketMy target market will be influenced by KEF.KEF speakers offer the highest quality of soundthere is. New technological advancementsmade by KEF have allowed there product to farexceed others. However to install thesetechnologies will come at a price. KEF’s targetaudience is not age specific however thereproduct are high-end, expensive speakers. Thiswould deter a younger audience who wouldtypically have less money to spend, howeverthe quality of sound and advanced technologydraws in customers with more money who arewilling to pay for the best in innovative andmodern sound systems. My target market willbe people aged 20+ which I feel is the optimumage group in which to attract people who canafford to by a high quality speaker. Through analysing my target market I have understood KEF’s target market in greater detail which will prove vital as I will be designing a speaker for KEF which will have a heavy influence on my design. I have chosen to use the same target market as KEF, the high end market.
LINKSFXLogical:Audio products can have various logical uses. The primary objective of a audio product is the sound it creates. These audio products can bein the form of speakers, surround sound, TV speakers, amplifiers for musical instruments, iPod docks and much more.Illogical:The are many ways in which audio products can be used in illogical ways. One is that with flat faced speakers people use them to standthings on which is an illogical use as it may effect sound quality and the speaker is not designed to hold the strain. Another illogical use iswhen people have several audio appliances which provide the same function. People often sit and stand on instrumental amplifiers whichcan damage the amp. The environment in which the audio product is put into is vital. Often people put there speakers on the ground whichis illogical as carpets take most of the sound and the sound is not directed at the hearer. Despite the primary function of a audio productbeing for its sound, people often buy the product just based on its aesthetics. Wires are also illogical as they take up space, do not lookaesthetically pleasing and can be unsafe. Some people choose to have/ design very large speakers which may have good functionalityhowever the space they take up is unpractical.Need:The audio product must be able to produce sound. The audio product must also have a power source that is sustainable as well as beingsafe to use in normal use.Keep:Energy supplied through mains electricity (wires). New technologies will be incorporated into my design as well as innovative, aestheticallypleasing shapes. The speaker will be a suspended speaker. The speaker will incorporate several speakers.Scrap: The standard cuboid shape of many audio products currently on sale. Visible cables will be covered to improve aesthetics and toavoid a tripping hazard. Also I would like to use a greater variety of colour and scrap the standard dull colours used on many currentproducts.From vs. Function:I will try to keep my product as balanced as possible. A similar technique has been adopted by KEF as they have made their product bothfunctional and organic. I feel that both function and form are equally important when designing a product , especially for KEF who arerenowned for both aspects.X-factor:My audio product will be different from other audio products as it will use unusual shapes with unusual materials choices. The speaker willinclude the latest in KEF technology which will make it a unique, interesting and investable product.
Primary and secondaryresearch planQuestionnaire:In this section I will create a questionnaire which will be putout to 20 people involved with the audio product market. Cultural understanding:Their thoughts about audio products will give me primary In this section I will look at a range ofinformation, of which will help me to make decisions on what different cultures and observe how the usematerials I should use, features I should include as well as and feel about audio products.

This willhelp me when constructing the internal structure of myspeaker.
Mood Customer ProfilingBoard My product will be heavily influenced by the target audience I am aiming at. Understanding my customer is vital, and will help me make important decisions around issues such as price, aesthetics, and function. Customers interested in buying my product will be interested in buying the highest quality speaker possible and will be willing to spend a reasonable amount of money to get it. I will be aiming my product at the high end market. I will use high quality materials and new technologies to optimise performance and give the customer a functional and aesthetically pleasing speaker which represents them. My speaker will be designed to fit into many different environments which are suited to the customer.From this mood board I can see that I want to have an organicapproach to my design. I want my speaker to be unique andmultifunctional like some of the speakers I have shown. In themood board I have also shown some pictures of things relatingto the design ideas I have which are related to my chosenenvironment.

Access FM of Secondary Product Aesthetics: The speaker has an organic design. It uses unusual shapes to make it look both unusual but natural. The design is meant to illustrate a tree with each speaker being a birds nest. The simplistic colours look modernistic and help to allow the design to blend into many different environments. Cost: The speakers can be bought individually or as a set depending on the needs of the user. The speakers are aimed at the higher end of the market due to their style, functionality and high quality finish. Customer: Due to their high price only people interested in buying a very high quality speaker would be interested in purchasing the speaker. Environment:Function: The speaker can be put into several different environments as I have alreadyThese speakers are highly functional due to their high said due to its very adaptable colour scheme.

There is a handle incorporated into the amplifier to allow it to be more poratble. This is very useful as the amplifier is heavy and if dropped could suffer serious damage.
Product disassemblyThis is the Ted Baker speaker I dissembled for my product disassembly. As you can see from the 2 images above the speakersfold outwards into two halves each with a speaker compartment. They are allowed to do so by the hinge shows in the right mostphoto. The sound is able to spread out by this method and the noise can be changed depending on how far open the speaker is.The speaker can rest open due to the flat edge of the base of the speaker shown in the middle right photo. An inlay has beenmade to host the cable which connects to an mp3 player or iPod. On the frontal face small holes (probably laser cut) have beencut to allow the sound to pass through.Here you can see the first stage of the disassembly. The backs of the speaker were held on to the front plates by 3 screws. Afterunscrewing these the back plates came off leaving the magnet, the diaphragm and the copper wiring on show. This is shown in thecentral photo. These components were hold on to the frontal face by screws and a resin which was very strong.

Research ReportIn my research I have done a several pieces of primary and secondary research. The primary research which I have carried out hasbeen a questionnaire, a product disassemble, an existing design analysis, Product interaction and an environmental snapshot. Eachhas provided me with key finding that will help me in the design of my speaker. My secondary research has also helped me greatly.The secondary research I have carried out is a mood board, customer profiling, ACESS FM of secondary product and culturalresearch.What I found out and am carrying forwardQuestionnaire:The questionnaire has helped me to gage a suitable price range between £10-80 for my product as well as a suitable environment to put thespeaker in and the best style to go for which from my result is organic.Product disassembly:This has helped me to find out exactly what procedures have been put in place to make sure the speaker is secure and safe for use and hastaught me how a speaker is held together.Product interaction:Through looking at a product first hand and witnessing its features and how it feels I now know what makes a audio product user friendlywhich will help me to incorporate similar features into my design.Existing design analysis:This section has helped me to decide what features I should include within my design and how they will effect the speakers usability. I havedecided to incorporate a form of acoustical amplifier within my design to enhance sound quality.Environmental snapshot:Through looking at the environment around the speaker it has helped me to see what logical and illogical uses I use my speaker for. With thisin mind I will design a speaker which enhances the logical features and tries to deter those illogical uses which may damage the speaker.Mood board , Customer profiling and cultural research:These secondary research techniques have helped me create an image of the audience I am aiming my product at which will help medramatically when designing my speaker. I now know that my target market is higher class people who use their products on a regular basiswho live in urban areas and are willing to pay a decant amount of money for a high quality, durable speaker.ACESS FM of secondary product:Looking at another product across the ACESS FM range has helped me to understand why a speaker is designed I the way it is to meet theneeds of all of the aspects. I now have a greater understand of what makes a good speaker and have decided to incorporate the hangingspeaker idea into my design.
DevelopmentThe design that I have chosen to use for my audio product is shownabove. The design incorporates a range of materials, shapes andaesthetics which epitomizes an organic, natural design. The designis wall mountable and has been influenced by the shape of a fireflywhich fits my brief of creating a nature based design. The back of my design, that will be attached to the wall, will be made of a green transparent plastic. I will use techsoft 2D design to create a template which will be sent to a laser cutter to be cut out. The template will be etched to form the leaf like structure which is intended to add to the organic nature of my design. The back face will have Magnets incorporated, held in place by resin so that the speaker can be mounted onto any wall that has a magnetic dock. The housing of the speaker will be located at the base of the design. The base will be made of oak and will incorporate all of the controls including the volume and power switch. I will create the oak base using multiple layers of oak sheet held together using PVA glue. Using a milling machine, the base will be hollowed for the speaker housing.
Aluminium Aluminium is a silvery white metal made of bauxite. When mixed with other elements aluminium alloys can be created with several good properties: It doesn’t corrode- due to passivation(aluminium oxide layer) Useful for if the speaker is in damp conditions (Bathroom/ kitchen) Has a low density making it lightweight. Good for the speakers portability as well as reducing the force put onto the magnets holding the speaker to the wall and to the pop rivets holding the wings in place. It is soft, ductile and malleable Meaning that the wings can be easily cold forged into shape around an MDF mould. It is durable Meaning the speaker will have longevity and the constant pivot of the wings will not damage the wings. Easily joined Aluminium can be joined using all the normal methods available such as welding, soldering, adhesive bonding and riveting. Non-toxic Aluminium is not poisonous and is therefore highly suitable for the preparation and storage of food.
Here is an illustration of how the base of my design will bemade up of several layers of MDF stuck together usingPVA. I will then clamp the template into position while itdries. I will use sandpaper to smooth and round the edgesonce the glue has set. Then using an electric drill I will cutout the grooves in which the metal threads for the wingscan be put into. An illustration of how the wing template will be made is shown to the left. I will sand the shape down until smooth to create an organic/ ergonomic shape then cold forge the aluminium around it.
LED’sThe base of my design will incorporateLED’s. These will help with both theaesthetics and usability of my design.Aesthetically it will help to make thedesign more similar to a fire fly as wellas this the light will make the speakermuch more usable in low lightconditions. To make my speaker capable to play music I have decided to include a docking station in my design. You can connect any device that has a 3.5mm audio jack to The Dock the speaker. This includes the Apple iPhone / iPad / iPod, any other MP3 Player. The speaker I will be using in my design is a 4” shielded bass/mid woofers which will provide me with a very good sound quality, without taking up too much space, looking out of place or using up too much energy.

Specification checkpointThe design I have created is highly functional. So far in my development I have shown how LEDscould be incorporated into my design for use in the dark which also improves on the aesthetics andthe idea of a firefly. I have also shown were the dock of my speaker will be situated. The speaker isalso portable and can be mounted anywhere in the house using a set of magnets which is what Isaid it needed from my initial specification. The wings also help to add to the acoustics of mydesign as they are adjustable to allow different measures of sound to escape. The materials I will be using in my design include aluminium for the wings, transparent acrylic for the back and an oak base to house the speakers. These materials replicate the high quality that KEF uses in its products. I have also altered the aesthesis of the design to make it look more organic and bug like. The design uses simple organic colours such as green as well as natural materials such as oak. The speaker is designed for inside use and can be placed around the house using magnets. The speaker is wall mounted and takes up little living space which is the main motivation in it being wall mounted. The speaker will not look out of place due to its natural, subtle, transparent colours which will help to incorporate the speaker into its surroundings. The safety of my design has been considered throughout my development and there are now no safety issues. There are no small components which can be swallowed nor any sharp edges which could be hazardous to the user especially at head height.
The wings will be made from aluminium. To create them I The back of the design will be made in a similar way to thewill make an MDF mould.

Front Plate The front plate and rim of my design will be made out of mirrored plastic. Both will be cut on a laser cutter and will be held on by self tapping screws. An indent will be made in the oak and then the screws will be ‘threaded’ into the wood using a Philips screwdriver. The speaker will fit into the oak housing and will be held in place by the plastic rim.Anthropometrics and ErgonomicsOn this page I will consider how my design could be developed to be more ergonomicand anthropometric.The volume buttons of my design will have a 2cm diameter.

The holes will be cut by a laser cutter and indents will be will be drilled into the wooden base so that it will be easier to thread the crews in. The reason for using self tapping screws is that they provided a very strong grip due to the thread they create which is essential as the speaker needs to be strong at this point to hold the speaker firmly onto the wall.
The Acrylic back plate will be attached to the oak base using an adhesive. I will have a strip of acrylic and will cover one side In adhesive. I will then place this along the joint line to hold the two materials together.Digital clock Another feature that I could Include Is a digital clock which would make my product multifunctional. Although it is a nice feature It is not in my design specification and is therefore not too important. To add to this the MP3, iPod, IPhone etc. All have time displays on them anyway making the use of a digital clock pointless.
