Stereobelt
From Wikipedia, the free encyclopedia
An ancestor of modern-day personal audio devices such as the iPod, the Stereobelt was a portable personal stereo audiocassette player invented in the year 1972 by the German Andreas Pavel.
A former television executive and book editor, Pavel invented the Stereobelt to "add a soundtrack to real life" by allowing the user to play high-fidelity music through headphones while participating in daily activities.
The initial test of the device took place in February 1972 in St. Moritz, Switzerland, when Pavel pushed the play button to start the song "Push Push" by Herbie Mann and Duane Allman. Pavel experienced a "floating" sensation as he listened to the music and watched the mountain snow fall, realizing that his new device could provide "the means to multiply the aesthetic potential of any situation."
Pavel approached electronics manufacturers such as ITT, Grundig, Yamaha and Philips with his invention, but the companies felt the public would never wear headphones in public for listening to music.
Frustrated with his lack of progress, and learning that it was important to protect his idea, Pavel finally filed a patent for the Stereobelt in Italy in 1977, followed by with patent applications in the U.S., Germany, the United Kingdom and Japan by the end of 1978.
Sony began selling the very similar Walkman personal stereo in 1979. In negotiations that began in 1980 and ended in 1986, Sony agreed to pay Pavel limited royalties for the sales of certain Walkman models sold in his home country of Germany only.
A second round of legal battles between Pavel and Sony that began in 1989 in Great Britain ended when the case was dismissed in 1996, leaving Pavel to pay more than $3 million in court costs.
Finally in 2003, with Pavel threatening to file infringement lawsuits in the other territories where he holds patents, Sony agreed to settle out of court. The settlement was reported to be a cash payment of over $10,000,000 and ongoing royalties of the sale of certain Walkman models.
