Gramophone - a creation and great invention, a machine that turned on the sound of the "past", yes, it is the famous American inventor - Thomas Alva Edison invented in 1877, since then, the era of music can only be listened to in the Grand Theater is over, an era of listening to music at home has arrived, the gramophone is also known as one of the greatest inventions of the 199th century (telephone, electric light)
In 1877, Edison built the first gramophone in human history and began to store media. From the original tin foil roller and steel needle playback, resulting in each drum can only be played a few times before wearing, to modern laser audio and video storage software DVD, has shown unparalleled audio and video realm in the 21st century. In the past hundred years, continuous innovation,
20th century: Vinyl record players swept the world for decades. Vinyl: LP/long play, a stereo black celluloid textured dense-grained record.
1958: Iohn C Koss's team invented the world's first portable stereoscopic phonograph, connected to headphones to listen to music.
1972: Andreas Pavel, a German-Brazilian, built the prototype of the "Walkman" with "portable tape playback system" and "headphones", and in 1978 applied for a patent and became the "inventor of the portable music device concept".
March 8, 1979: Philips of the Netherlands demonstrates a digital music playback system based on laser CD-ROM CD.
July 1, 1979: The TPS-L2, the world's first portable tape player for the Sony Walkman, is born. The first TPS-L2 hatch had Stereo printed on it, not a Walkman. It was unified as the Walkman at the end of 1980. The Walkman sold 1 million units in the first year, 50 million units in the first decade, and 100 million units in the next three years. Sony demanded that Andreas Pavel give up his status as the "inventor of the portable music device concept" and continued a 25-year tug-of-war before the two sides reached a settlement in 2003. Sony, Panasonic, Aihua and other manufacturers have been selling for almost 20 years.
October 1982: Sony introduces the WM-7 using auto-tape, repeating and noise reduction for the first time
February 1983: Sony's first sporty waterproof Walkman WM-F5 is launched
October 23, 2001: Apple introduces the first generation of iPods, 5G large capacity + palm size and easy to control, making the $399 player a hit, ending the 20-year dominance of the Sony Walkman portable tape player.
However, the pace of exploration never stops. While the music player is iterating and developing rapidly, another technology is also developing rapidly.
We talked about the development process and working principle of Bluetooth in previous literature, and Bluetooth evolved step by step from the initial military communication to LE ultra-low energy Bluetooth audio transmission. Bluetooth audio is growing rapidly,
When Bluetooth and music players collide together at a certain point in time, an epoch-making product was born again, Bluetooth headphones (speakers), from only supporting mono to today's true wireless (TWS) headphones, from only supporting very low sound quality to today's LHDC Hi-Res, which means walking into everyone's side to replace people's last half-meter cable (headphone cable),
Now the music playback equipment has entered the Bluetooth era, but in the past for a long time, the birth of a variety of large, large and small speakers, and we know that Bluetooth is only a communication technology that spreads audio, can only change the way of music transmission, and can not change the music itself, since Bluetooth can be installed in new equipment, of course, you can also upgrade the equipment, only need a small Bluetooth box to connect to the mobile phone or computer, you can output audio to the old speaker through the cable,
Because iPod has amazing sales in the world, and the major speakers have also launched iPod socket desktop speakers, according to incomplete statistics sales of hundreds of millions of units, among which the more prominent manufacturers are Bose, JBL, Sony, YAMAHA, Philips, B&W, etc., there are still many speakers placed on our desktop or a corner, in the era of Bluetooth audio domination, if we continue to use the old equipment seems a little out of step with the times, if discarded and reluctant, After all, the price of iPod audio was not cheap, and the sound quality was incomparable with today's Bluetooth audio,
The iPod jack speaker is connected to the iPod through the 30-pin jack to transmit audio, which makes it easier for us to upgrade the speaker, just design a Bluetooth box of the same size as the iPod, and the box is equipped with a 30-pin output jack to connect with the speaker, so that you can plug and play like the iPod, easily get streaming music, and you can also remotely control the song/adjust the volume and turn off the music through the mobile phone. This can not only revive our old devices, but also make the control simpler, the disadvantage is that the sound quality is slightly inferior to the iPod, but the maturity of Bluetooth lossless transmission makes this gap no longer so obvious.
Fanxoo will explore more about the use of the Bluetooth Audio with you，and if you have a better discovery, please share it with us. Thank you ！
