The Regency TR-1 was the first portable audio device made for commercial purchase in 1953, by I.D.E.A. The TR-1 was a small portable radio receiver, it was called the transistor radio because the technology it used was transistor-based circuitry. which meant you could listen to the radio while mobile. It had an AM and FM tuner, and came in a variety of colors. The price for the TR-1 was $49.95, but that was over 50 years ago, in today’s dollars it would be equivalent to around $325, so the TR-1 was quite expensive.
The KLH was the first portable stereo developed by Henry Kloss in 1962. The KLH was a record player, amplifier, and two speakers all folded up into a “suitcase” that you could easily transport.
In 1979, Sony introduced the first portable music player, the TPS-L2 Walkman. The Walkman went on sale in Japan in July 1979 and almost a year later it was introduced in the U.S. In the UK, it came with stereo playback and two mini headphone jacks, allowing two people to listen at the same time. The Walkman had a &quot;hotline&quot; button which activated a small built-in microphone, partially overriding the sound from the cassette, and allowing one user to talk to the other over the music without removing their headphones.
The Walkman was popular for audio until the late 1980’s when the portable CD player entered the market and took over popularity. In 1984 Sony introduced the D-50, which was the first portable digital music player on the market. The CD player allowed you to skip from one track to the next by the click of a button, which was so much more efficient then rewinding and fast-forwarding a cassette tape. Also CD’s had better sound quality and were not subject to tape damage that cassettes were. The compact disk was the new technology and the cassette tape was soon to be forgotten. Although CD’s were more practical then the cassette tape, CD’s still had flaws; CD’s were prone to scratches which would affect audio playback, and until anti-skip technology, CD’s often skipped when the laser readers inside were shaken. So even though the CD player became the dominant choice for portable music, the Walkman was still popular for athletes until anti-skip technology was introduced.
The Mini-Disc player, a compact, much smaller version of the portable CD player. The Mini-Disc player has CD-quality audio while being about half the size of a portable CD player, which made it an upgrade from the portable CD player. They come in a plastic caddy, protecting the disc's surface from dust and scratches. The players are able to playback and record Mini-Discs from digital and analogue sources, such as live audio from their microphone inputs. So with the Mini-Disc player having all these features plus being so compact, today being not much larger than the mini-discs themselves, they became much more popular than the portable CD player.
The MPMan was the first MP3 player introduced to the market in 1998. The MPMan was made by a Korean company named SaeHan Information Systems, and was imported into the United States by Eiger Labs. It had 32MB of RAM which is equivalent to about 32 minutes of music. The RAM was expandable to 64MB but you had to send it back to Eiger. Although it only had 32MB of memory which compared to audio devices today is not a lot, it had 9 hours of battery life which is still better than many players even today.
there are multiple options when it comes to using dictation devices and software. Devices like those pictured have their own internal memory that allow you to record a variety of media and can also double as a mass storage device providing a multifunctional alternative to things like usb keys. Dictation software is also very convenient, allowing automatic transcription for those who are not advanced at typing, those who can speak their ideas faster than they can type them or simply need to keep their hands free while making notes. NHC software and Nuance both provide programs of note, namely the Dragon NaturallySpeaking series.
with the use of cell phones being so popular now, we basically walk around with a mini computer in our pocket. so naturally, you should be able to do everything you would be able to do on a lap or desktop while mobile. being the multi purpose device that they now are it makes sense to consider a cell phone a portable audio device because they have the ability to record and playback audio, you can purchase music via mobile data, and even use them as a dictation device with downloadable apps that are available bringing up once again the dragon software which is actually available for different mobile platform making it easy to speak and have your words instantly turned into emails, notes, or text messages.
In over 50 years portable audio devices have evolved from basic transistor radios to the contemporary media devices we have today and Undoubtedly many more advances are yet to come.
