Now, the Bluetooth headset is no longer a rare digital product. To know that a few years ago, the Bluetooth headset were something that many people probably wouldn’t have heard of. Thanks to the development of Bluetooth technology and the popularity of smart phones, the convenience of Bluetooth headset has been more and more attention and use in the ever-changing technology era, .
The concept of Bluetooth was first introduced in 1998. The Bluetooth standard used today is different from today’s band, and the speed of transmission is different from that of today. Bluetooth has been defined as a short – distance radio connection since birth, which coincides with the modern mobile and wireless convenience scene.
However, due to the beginning of the Bluetooth standard is not uniform, price, cost and other issues, for several consecutive years did not develop, or even almost died, until the end of 2005 before bottoming out. This is a certain reason, at this stage, more and more rich entertainment feature phone, especially for the transmission of multimedia data transmission between the mobile phone to mobile phone is particularly important, directly stimulating the development of Bluetooth technology.
Because of this, Bluetooth headsets have been pushed to a greater degree. Anyone who knows a bit about Bluetooth will know that Bluetooth Connections depend on the specific work of Bluetooth protocols. With the accelerated development of Bluetooth, Bluetooth audio transmission protocol A2DP emerges as the times require. The protocol gives the stereo sound of Bluetooth headsets, which are much more pronounced than the mono Bluetooth, which makes it easier to hear.
After several generations, until now the Bluetooth 4.2, Bluetooth technology overall towards faster transmission speed and lower power consumption, higher signal-to-noise ratio and better transmission direction, for data transmission loss of Bluetooth headset is also more and more low, let the song loss when playing more and more close to the effect of a wired headset.
Now Bluetooth headsets can be divided into two broad categories:
One is Bluetooth headset, which is mainly transmitted by mono channel, which is a convenient communication device for business, traffic and so on;
The other is Bluetooth music headsets, which require higher headphones because of the different main transmissions.
Compared to wired headsets, the internal structure of Bluetooth headsets is much more complex. In addition to the Bluetooth chip, you also need to decode the module circuit board, rechargeable battery module, etc., and Bluetooth headset on the market will usually integrate line by wire and microphone call function.
The usual practice is to install a part of the connection line like wired headphones, integrated with line control, microphones, Bluetooth, and batteries. Of course, this part of the volume than the wired headset wire part, so the structure of the headset is a little bit and no communication headset that New problems crop up unexpectedly., the simple lines of beautiful feeling; at the same time, also produced a bilateral unequal, running easy to shake the new problems.
