A portable music player is a consumer electronics device that allows users to listen to recorded music on the go. It is battery powered, and in some cases, accommodates the use of headphones for personal listening. Some early music players did not store music, but rather played music stored on other media.
From phonograph to record player
The first successful attempt to record sound signals was achieved in the late 1850s by Edouard-Leon Scott de Martinville who invented the first sound transcription device, called the phonautograph. It was able to record music, but did not support audio playback.
Inventor Thomas Edison furthered the work done with this technology with the invention of the phonograph which pioneered recording and playback, and paved the way for future innovations.
Flat discs, much like LP records, were used just over 10 years later on the gramophone, marking the start of the rise of the music industry. The gramophone operated on a hand-crank. In 1925, electric record players were introduced to the market.
Although it did not contain recorded music, the first portable transistor radio debuted in 1954. Called the Regency TR -1 radio, this device was available in a variety of colors and featured an analog tuner.
Among the first attempts at taking recorded music outside of the home for personal use was in 1965 with 8- track tapes that are played back in the car.
However, in 1962 the KLH Model 11,, developed by Henry Kloss, was the first transistorized stereo system that ran on A/C power. It featured a record player, amplifier, and speakers that folded together easily for the purpose of transporting the system. While these devices were not portable by today’s standards, they are major milestones in the evolution of the portable music device.

|2007 – 2008||iPod Touch,, incorporates applications and touch screen|
As with any electronics, technology advances often result in more capabilities in a smaller overall package, as is the case with music players of today.
Portable Cassette Players
The Sony Walkman revolutionized the industry with its introduction into the market in 1979 in Japan. The self-contained portable music system, which came with lightweight headphones, played cassette tapes and was capable of Hi-Fi stereo sound.
Although early versions were a little bulkier, the refined Walkman was considered innovative due in large part because of its size, as it measured only slightly larger than the cassette tape itself and ran on AA batteries. Several companies were quick to adopt this technology and came out with competing products.
The use of cassette tapes for portable cassette players was innovative, as the media was less bulky than 8-track tapes and users were able to move from song to song more easily. Some portable cassette tape players also had the ability to play AM/FM radio.
Portable CD Players
In 1983, Sony partnered with Philips to create the D-50 which became commonly known as the Discman . It played compact discs and was the first portable digital music player. The Discman certainly made music portable, but it was less comfortable due to its larger size. Users were also limited to the number of songs that could be contained on one disc.
The Discman was just slightly larger than a CD case. Over the coming years, discs became smaller and music players became lighter, more compact, and pocket-sized.
The other issue with portable CD players was that if bumped or jarred in any way, the laser beam orientation system could be affected, causing it to skip music. This issue was later addressed by creating a buffer which was used to read ahead and store music. If the disc skipped, the device would pull data from the buffer to continue the music until the buffer was empty. Eventually, anti-skip technology was developed.
The rise of CDs signaled the end of cassette technology in the late 1980s, as CDs produced higher quality sound and the ability to easily skip tracks rather than forwarding or rewinding tape.
The MP3 file format uses a compression algorithm that reduces the amount of data needed to store audio track information. The average size of an MP3 file is one-tenth the size of a file on CD.
In 1999, the MPMan was the first flash MP 3 player to be released, allowing high quality digital music recordings that do not skip when played to be transferred from computers to portable players. Developed by Korean company SaeHan Information Systems and imported to the U.S. by Eiger Labs, the player featured 32 MB of RAM and held an average of 32 minutes of music. It ran on a rechargeable NiMH battery pack and used solid-state memory.
As technology advanced, MP3 devices became smaller, sleeker, able to hold more data, and more functional. Some of today’s MP3 players include the ability to play video as well as audio.
The first entry into this market from Apple was the iPod in 2001. The iPod Classic combined 5 GB of hard drive space with a rechargeable battery pack. While it operated much like MP3 players introduced before it, it had a sleeker design and a unique and simple navigation system.
iPods initially only worked with Macintosh computers, and the only way to import music to the player was from one’s own CDs or downloads from the Internet. In 2003, iTunes was launched, allowing users to legally download songs for a fee per track. Soon after, Apple introduced a Windows-compatible version of iTunes, widening the reach to more users.
Over the years, Apple continued to release smaller and sleeker versions of their portable music players, such as the Nano,, Shuffle,, and iPod Touch . Ultimately, Apple combined the functionality of its music players with cellular phone functionality with the introduction of the iPhone .
Portable music players have undergone an interesting evolution since the beginnings as a transistor radio. That device, however, was the start of a major revolution in the music industry. People were no longer tied to their home or cars to enjoy their favorite music.
Music players followed the trend in music, as media such as cassette tapes, CD players, and flash memory evolved. The sound quality and consistency of music played also evolved with the technology, as well as the ability to carry more varied music in a smaller device. The interface has also evolved, from tuner wheels on radios, to function buttons on portable cassette and CD players, to touchscreen technology used on many digital audio players today.
Today’s portable music players include additional features and functionality, such as the ability to record and play back video, take pictures, and more. In the case of Apple, the combining of music technology into their iPhone allows users to carry one device that allows them to carry their entire music library with their cellular phone. And of course there is Google Glass which will bring us the future of portable
