Low-power-consumption one-to-two Bluetooth headset

Abstract

The invention provides a low-power-consumption one-to-two Bluetooth headset. The Bluetooth headset comprises a main headset and a secondary headset, wherein a first Bluetooth chip is embedded into the main headset; the main headset comprises a first Bluetooth physical layer; a second Bluetooth chip is embedded into the secondary headset; the secondary headset comprises a second Bluetooth physical layer; the first Bluetooth physical layer comprises a first 2.4GHz radio-frequency module and a first 10MHz radio-frequency module; the second Bluetooth physical layer comprises a second 10MHz radio-frequency module which has the same structure as the first 10MHz radio-frequency module, and a second 2.4GHz radio-frequency module which has the same structure as the first 2.4GHz radio-frequency module; the first 2.4GHz radio-frequency module communicates with audio playing equipment; and the first 10MHz radio-frequency module and the second 10MHz radio-frequency module perform microwave communication, and are used for switching microwaves between 2.4GHz and 10MHz. The first Bluetooth chip in the main headset communicates with the second Bluetooth chip in the secondary headset through a Bluetooth protocol, and 2.4GHz radio frequency is switched to 10MHz radio frequency through the main headset, thereby effectively lowering the power consumption, and effectively prolonging the service time of the headset.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a low-power consumption one-to-two Bluetooth headset. Background technique [0002] With the progress of society and the improvement of people's living standards, earphones and speakers have become indispensable daily necessities in people's lives. Traditional wired headphones are connected to playback devices through wires, but they restrict the wearer's movement, especially in sports situations. Ordinary Bluetooth headsets cancel the connection between the headset and the playback device, but there is still a connection between the left and right ears. True Wireless Stereo (TWS) headphones and speakers came into being. [0003] The working principle of the existing TWS earphones is that the main earphone is connected to the playback device and the auxiliary earphone at the same time through the Bluetooth one-to-two technology. The audio data of the other channel is sen...

Problems solved by technology

[0004] Due to the serious interference on the 2.4GHz working frequency band of Bluetooth, for example, the WiFi signal in the same frequency band will occupy a large bandwidth, and the structure of the human head will seriously attenuate the 2.4GHz signal between the left and right ears, which will cause The air signal quality deteriorates during the interval, which eventually leads to stuttering or increased delay
