The Walkman ® or tocapaseo is a stereo audio
Portable launched by the Japanese company Sony in 1979.
The first model was the TPS-L2. From this model and its
subsequent revisions, Sony sold millions of units, but when
it appeared, few could afford one due to its high price.
The walkman allowed to get quality sound, similar to a home
stereo, without being so bulky. The wide dissemination of
walkman also radically changed the business of the turntable and
gave the first blow to the vinyl record, as the cassette was easier
to play and more economical
Andreas Pavel, German-Brazilian inventor, is credited with the
invention of the first portable stereo audio in 1972. Pavel studied
philosophy and participated in several intellectual and creative
movements, was a great lover of music and the fact that constantly
displace led him to devise the "belt stereo". During the military
dictatorship, he was exiled in Europe, tried to sell his idea to
several companies but these did not see your idea with favor and
Pavel finally patenting his invention.
Sony began negotiations with Pavel about the copyright of the
invention, and recognized, in 1986, which would be paid royalties
for his invention, without recognizing intellectual property.
Interestingly, as they told the founders of Sony, its creation was due
to a warm morning in 1979, Masura Ibuka (one of the founders of
Sony) she wanted to listen to music while running, so I
immediately looked for ways to turn their ambitions. To do this,
extracted the recording circuit and placed a tape recorder stereo
amplifier with headphones.
In the early '80s, Sony, Toshiba, Aiwa, Panasonic and Sanyo were
the main producers of these devices, the user benefit was
remarkable: for the first time anyone could go out and listen to your
music favorite anywhere. Each manufacturer literally snapped his
head to find the most suitable name to an artifact as attractive as
eccentric. No brand wit surpassed Sony, whose Walkman was
positioned as the global benchmark appellation. While Sony's
marketed under the brand name "Walkman", Toshiba opted for
"Stereo Walky" and Panasonic "Stereo-To-Go".
The Sony Walkman is considered the greatest technological
invention of the last 50 years.
Besides being able to listen to the radio, the
Walkman was also the ability to play music
by inserting a cassette in the Walkman.
Young people began to purchase their portable players for $ 150.
Competition also put into circulation disposable products that did
not exceed $ 20, but the audio quality was low or negligible.
