Sony Walkman
is a brand of portable audio players manufactured by Sony since 1979. It was originally introduced as a portable cassette player and later expanded to include a range of portable audio products. Since 2011, the brand has referred exclusively to digital flash memory players. The Walkman became widely popular during the 1980s for its portable design and private listening experience. It influenced popular culture by promoting individualized music consumption and supporting activities such as aerobics. Its widespread use gave rise to the "Walkman effect," a term describing how portable music devices and headphones allow listeners to control their sonic environment. In 1986, "Walkman" was added to the Oxford English Dictionary, and in some markets the term became a genericized trademark for portable audio players. The Walkman also contributed to the widespread adoption of the Compact Cassette format, which surpassed vinyl record sales in 1983. Sony sold approximately 220 million ...

MiniDisc
MiniDisc (MD) is an erasable magneto-optical disc-based data storage format offering a capacity of 60, 74, or 80 minutes of digitized audio. Sony announced the MiniDisc in September 1992 and released it in November of that year for sale in Japan and in December in Europe, North America, and other countries. The music format was based on ATRAC audio data compression, Sony's own proprietary compression code. Its successor, Hi-MD, would later introduce the option of linear PCM digital recording to meet audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan and found moderate success in Europe. Although it was designed to succeed the cassette tape, it did not manage to supplant it globally. By March 2011, Sony had sold 22 million MD players, but discontinued further development. Sony ceased manufacturing and sold the last of the players by March 2013. On January 23, 2025, Sony announced they would end the production of recordable MD media ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akio Morita

Morita's family was involved in sake, miso and soy sauce production in the village of Kosugaya (currently a part of Tokoname City) on the western coast of Chita Peninsula in Aichi Prefecture since 1665.

Wasei-eigo
are Japanese-language expressions that are based on English words, or on parts of English phrases, but do not exist in standard English, or do not have the meanings that they have in standard English. In linguistics, they are classified as pseudo-loanwords or pseudo-anglicisms. Definition and examples ''Wasei-eigo'' words, compound words and portmanteaus are constructed by Japanese speakers on the basis of loanwords derived from English and embedded into the Japanese lexicon with refashioned, novel meanings diverging significantly from the originals.Miller, L.

Personal Stereo
A personal stereo, or personal cassette player, is a portable audio player for cassette tapes. This allows the user to listen to music through headphones while walking, jogging or relaxing. Personal stereos typically have a belt clip or a shoulder strap so a user can attach the device to a belt or wear it over their shoulder. Some personal stereos came with a separate battery case. History The Sony Walkman was released in 1979, created by Akio Morita, Masaru Ibuka (the co-founders of Sony) and Kozo Ohsone. It became a popular and widely imitated consumer item in the 1980s. In everyday language, ''walkman'' became a generic term, referring to any personal stereo, regardless of producer or brand. The spread of personal stereo devices contributed to tape cassettes outselling vinyl records for the first time in 1983. The introduction of the personal stereo coincided with the 1980s aerobics vogue, making it very popular to listen to music during workouts. Moreover, the prevalence o ...

He is credited with spurring the development of the compact disc (CD) as a commercially viable audio format. Biography Early career Ohga was born in Numazu, Shizuoka.

As a young man, Ohga aspired to be a professional opera singer, and went on to read at the prestigious Tokyo National University of Fine Arts and Music, graduating in 1953. His relationship with Sony began when he wrote a highly critical letter to Tokyo Tsushin Kogyo KK (also known as Totsuko and later as Sony), complaining about their tape recorder's many failings, which got him noticed by Masaru Ibuka, Akio Morita and other Totsuko executives. Because of his insight into music and technology, the company hired him as a part-time consultant. Ohga went on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock (mechanics)
In mechanics and physics, shock is a sudden acceleration caused, for example, by impact (mechanics), impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity). The unit ''g'' (or ''g'') represents multiples of the standard acceleration of gravity and is conventionally used. A shock pulse can be characterised by its peak acceleration, the duration, and the shape of the shock pulse (half sine, triangular, trapezoidal, etc.). The shock response spectrum is a method for further evaluating a mechanical shock. Shock measurement Shock measurement is of interest in several fields such as *Propagation of heel shock through a runner's body *Measure the magnitude of a shock need to cause damage to an item: fragility. *Measure shock attenuation through athletic flooring *Measuring the effectiveness ...

Stereobelt
The Stereobelt was a personal stereo player devised by Andreas Pavel, a former television executive and book editor. Pavel filed a patent of invention for his portable music player in Italy in 1977, and adopted the same protective steps in Germany, United Kingdom, United States, and Japan. He sought royalty fees and later commenced legal proceedings against Sony Corporation after the Walkman released commercially in 1979, believing the electronics manufacturer had infringed his intellectual property. Judges ruled against him, revoking the patent, stating his concept was "not significantly inventive". Background and history A former television executive and book editor, Pavel devised the Stereobelt to allow the wearer to play high-fidelity music through headphones while participating in daily activities. He states the initial test of prototype hardware took place in February 1972 in St. Moritz, Switzerland. After he pushed the play button to start the song Push Push by Herb ...

Phonograph Record
A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm, giving it the nickname "78s" ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing the old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs pla ...
