Tws bluetooth headset under development Bluetooth technology R & D in the 5G era
The application direction of Bluetooth technology is very wide, not only for data transmission, but also the possibility of developing its short-distance positioning. The application of Bluetooth technology on headphones has brought the impact from 2000 to now, and the biggest personal experience is convenience plus intelligence from a development perspective. Bluetooth headsets got rid of the shackles of wire. In 2016, Apple's mobile phone took the lead in canceling the 3.5mm headphone port, which gave the Bluetooth headset a greater momentum for development and the market expansion was self-evident. Entering 2019, TWS true wireless Bluetooth headsets have experienced explosive growth, and with it comes numerous brands of various wireless Bluetooth headsets.
1. In 1994, Ericsson developed Bluetooth technology
The main purpose of Ericsson's R & D for Bluetooth technology is to eliminate the traditional serial data cable (RS-232 interface) and provide better information transmission methods for products.
2. Named Bluetooth by Intel engineers in 1997
In 1997, the term Bluetooth originated from Scandinavian language was proposed by an engineer at Intel and finally named Bluetooth as we know it today.
3. The first wireless Bluetooth headset was launched in 2000
The first Bluetooth headset uses Bluetooth version 1.0, which can only allow voice to be transmitted in mono, and can only meet the needs of calls. It is limited to headphones, and its purpose is only to prevent people from disturbing others when watching movies in the living room.
4. Stereo Bluetooth headset appeared from 2001 to 2010
Bluetooth technology has been continuously improved and improved in the past 10 years, and finally stereo Bluetooth headsets have appeared, mainly headsets (with Bluetooth chips and batteries installed), earbuds have not yet appeared, and the battery life is also difficult for Bluetooth headsets Important constraints.
5. In-ear earphones appeared around 2011
The earplug type earphone connects the earplugs on both sides with a short wire, and inherits the battery and circuit in the earplug, and then adds the wire control function. Lightweight, easy to carry, and has good battery life, which greatly improves the consumer experience. In terms of sound quality, as well as sound delay and endurance, there has been a great improvement. The application of new encoding technology has made the sound quality of Bluetooth headsets reach the level of sound source playback that can support CD specifications or lossless specifications.
6. The first true wireless Bluetooth headset appeared in 2015
The first true wireless Bluetooth headset in 2015 was the W800BT released by Onkyo of Japan at the 2015 IFA show.
Then in 2016 Apple launched Airpods true wireless Bluetooth headset.
7. Update Bluetooth 5.1 version in 2019
In January 2019, the Bluetooth Technology Alliance (SIG), the governing body of Bluetooth, announced that Bluetooth 5.1 now available to developers will bring enhanced positioning services to Bluetooth-enabled devices. Twenty years have passed since 1994, and Bluetooth technology has been continuously improved, and finally there is the current Bluetooth 5.1 version.
Bluetooth technology is still one of the most important technical standards in the field of wireless communication technology today.
From the development history of Bluetooth headsets, the future development of Bluetooth headsets will also be improvements and improvements in improving sound quality, battery life, and sound delay. Of course, the implantation of smart AI in the future headsets will also become more and more common. Our demand for Bluetooth headset functions will become more and more user-friendly. What impact will the arrival of 5G have on the blue headset, and what kind of reform and update will the Bluetooth headset bring to us in 2020, we will wait and see.
