Description
Technical field
The present invention relates to bluetooth headset technical field more particularly to a kind of bluetooth headsets.
Background technique
Bluetooth headset exactly applies Bluetooth technology in hands-free headsets, allows user that can exempt leading for irritating electric wire
It stumbles, the easily call in various ways of comfortable ground.It has been always the good of Mobile Commerce race raising efficiency since bluetooth headset comes out
Tool.
Present market bluetooth headset is broadly divided into two major classes: "true" is wireless and "false" is wireless, and so-called is very wirelessly exactly similar
Product as apple AirPods, Meizu wireless headset, being truly realized does not have any connection line.And false is then wirelessly similar neck
Circle hangs that of earphone, or headphone, is still connected by earphone cable between the ear of left and right, and such product is at most only
It can be referred to as " I tech clip S ".
Existing "true" wireless Bluetooth headsets, when in use, earphone play music with stereosonic sound channel mode, by audio
It is divided into L channel and right channel is respectively allocated to two earphones, solid can be enjoyed for ears all wear the user of earphone
The hearing enjoying of sound, but when user only wears an earphone, earphone still play stereo, will lead to what user heard
This is the sound of a sound channel.
Summary of the invention
The purpose of the present invention is to provide a kind of bluetooth headsets, have stereo turn when user only uses an earphone
Shift to the advantages of monophonic mode plays audio.
Above-mentioned purpose of the invention has the technical scheme that
A kind of bluetooth headset, including the first earphone, the second earphone, bluetooth module, processing module and audio-frequency module, further include distance
Sensing module for detecting the distance between the first earphone and the second earphone, and is converted into distance signal and is sent to processing module；
When the processing module judges that the distance between the first earphone and the second earphone are greater than pre-determined distance according to distance signal, mould is handled
Block controls audio-frequency module and the sound channel of audio is adjusted to monophonic from stereo.
Further, the Distance-sensing module includes receiver and transmitter.
Further, further include clock module, be used for timing.
Further, the method for the distance between described Distance-sensing module test earphone specifically: in the first earphone
Processing module control transmitter issues detection signal, and clock module starts timing this record time started simultaneously, in the second earphone
When receiver receives detection signal, the processor control transmitter of the second earphone issues feedback signal, the receiver of the first earphone
After receiving feedback signal, clock module stops timing and records dwell time, according to the difference of time started and dwell time
It obtains and propagates duration, the distance between the first earphone and the second earphone are equal to the one of the product for propagating duration and signal velocity
Half.
Further, when the distance between the first earphone and the second earphone is not detected in Distance-sensing module, mould is handled
Block controls audio-frequency module and the sound channel of audio is adjusted to monophonic from stereo.
Further, when the first earphone does not receive the audio signal of player transmission and the second earphone receives audio
When signal, requested by bluetooth module to the forwarding that the second earphone transmits and receives audio signal, when the bluetooth module of the second earphone
When receiving forwarding request, the bluetooth that the audio signal received is forwarded to the first earphone by bluetooth module of bluetooth module
Module.
In conclusion the invention has the following advantages:
Bluetooth headset of the invention will play the mode of audio from stereo switching when user only uses single earphone and listens audio
When to monophonic, to make user when listening audio using single earphone, it still is able to listen to complete audio.

Specific embodiment
Below in conjunction with attached drawing, the technical solution of the embodiment of the present invention is described.
A kind of bluetooth headset, as shown in Figure 1, including the first earphone 1 and the second earphone 2, not over number between the two
It is connected according to line.Belong to "true" wireless headset.
As shown in Fig. 2, being provided with bluetooth module 3, processing module 4, clock module in the first earphone 1 and the second earphone 2
7, audio-frequency module 5, Distance-sensing module 6 and clock module 7.Bluetooth module 3 is for the data transmission between player.Processing
Module 4 is handled and is issued for receiving data, to data control instruction.Distance-sensing module 6 is for detecting the first earphone 1
The distance between second earphone 2, and be converted into distance signal and be sent to processing module 4.Clock module 7 is used for timing.Distance
Sensing module 6 includes receiver 61 and transmitter 62.In an embodiment of the present invention, pass through between receiver 61 and transmitter 62
Electromagnetic wave carries out model transmission.The method of the distance between 6 test earphone of Distance-sensing module specifically: in the first earphone 1
4 control transmitter 62 of processing module issues detection signal, and clock module 7 starts this record of timing time started, the second earphone simultaneously
When receiver 61 in 2 receives detection signal, the processor control transmitter 62 of the second earphone 2 issues feedback signal, the first ear
After the receiver 61 of machine 1 receives feedback signal, clock module 7 stops timing and simultaneously records dwell time, according to the time started with
The difference of dwell time, which obtains, propagates duration, and the distance between the first earphone 1 and the second earphone 2 are equal to propagation duration and signal passes
Broadcast the half of the product of speed.That is s=v t/2.Wherein, s is distance；V be electromagnetic wave propagation speed, about 3 × 108m/s；t
To propagate duration.
As shown in figure 3, when Distance-sensing module 6 is able to detect that the distance between the first earphone 1 and the second earphone 2
When, distance signal is sent to processing module 4 by Distance-sensing module 6, and processing module 4 judges the first earphone 1 according to distance signal
When the distance between second earphone 2 is greater than pre-determined distance, processing module 4 controls audio-frequency module 5 for the sound channel of audio from solid
Sound is adjusted to monophonic.
As shown in figure 4, when the distance between the first earphone 1 and the second earphone 2 have exceeded the measurement of Distance-sensing module 6 away from
From when that is, Distance-sensing module 6 can not detect the distance between the first earphone 1 and the second earphone 2, processing module 4 controls audio
The sound channel of audio is adjusted to monophonic from stereo by module 5.
As shown in figure 5, bluetooth headset of the invention, has exceeded the audio signal between player in a wherein earphone
Transmission range and another earphone without departing from audio signal transmission apart from when.The earphone of the audio signal still received can be passed through
As relaying, audio signal is sent to by the earphone without departing from audio signal transmission distance by bluetooth.
Specifically, when the first earphone 1 does not receive the audio signal of player transmission and the second earphone 2 receives audio
When signal, requested by bluetooth module 3 to the forwarding that the second earphone 2 transmits and receives audio signal, when the bluetooth mould of the second earphone 2
When block 3 receives forwarding request, the audio signal received is forwarded to the first earphone 1 by bluetooth module 3 by bluetooth module 3
Bluetooth module 3.In one embodiment, when user not only wants to listen audio, but also immovable player, the position of user with
When the distance of player has exceeded the transmission range of bluetooth, one of earphone can be placed on to the maximum distance that can receive audio
As relaying, another earphone is worn on ear.User can be in the double-wide of the critical distance of the transmission of bluetooth in this way
Inside listen to audio.
