In the embodiment of the present application, Bluetooth protocol, proprietary protocol or other lives can be passed through with other equipment such as electronic equipments
The earphone that order etc. is established bluetooth connection, and carried out data transmission, is defined as bluetooth headset, such as TWS (True Wireless
Stereo) earphone, TWS Plus earphone etc..
One electronic equipment can be attached with a bluetooth headset by Bluetooth protocol, can also pass through in parallel or string
The mode of connection is connected to two bluetooth headsets.Wherein, mode in parallel is, as shown in Figure 1, electronic equipment 600 is according to bluetooth
Agreement directly carries out bluetooth connection with bluetooth headset A and bluetooth headset B simultaneously；Concatenated mode is, as shown in Fig. 2, electric
Sub- equipment 600 is with one of bluetooth headset A bluetooth connection, the bluetooth headset A bluetooth connection again with electronic equipment bluetooth connection
To another bluetooth headset B.
When electronic equipment 600 connects a bluetooth headset, when carrying out audio broadcasting, the indigo plant is sent by audio data
Tooth earphone plays；When electronic equipment 600 connects two bluetooth headsets, audio number can be sent simultaneously to two bluetooth headsets
According to playing out two bluetooth headsets.Wherein, when electronic equipment 600 connects two bluetooth headsets, if side in parallel
Formula, then electronic equipment 600 directly can send two bluetooth headsets for audio data simultaneously；If concatenated mode, then may be used

Wireless bluetooth headset is not connected with power supply, if the electricity up time after charging is too short, will increase filling for user
Electric frequency reduces the usage experience of user.Either, it is used after user's charging in the case where that can not charge, very using the time
Then because low battery is not available in the case where short, and user can not charge at this time, reduce the usage experience of user.Cause
This, needs that bluetooth headset is made to have electricity-saving function.
Inventors discovered through research that the data volume of bluetooth headset processing is bigger, the data volume of such as transmission is bigger, solves yardage
Bigger etc. according to the bigger and played data amount of amount, the electricity of consumption is bigger.Therefore, the feelings played in the sound for guaranteeing to need to play
Under condition, the data processing amount of bluetooth headset is reduced to a certain extent, bluetooth headset can more power saving.
And audio data is carried out bluetooth volume when passing through blue tooth transmission audio frequency data with certain encoding rate by electronic equipment
It is sent to bluetooth headset after code, encoding rate is lower, and the data after coding are smaller, and the received data of bluetooth headset are smaller, needs
The data for decoding and playing are smaller.By taking mp3 file as an example, mp3 file is decoded as PCM (Pulse Code by electronic equipment
Modulation) file, then by PCM document No. be the file that can be transmitted by bluetooth, such as AAC (Advanced
Audio Coding, Advanced Audio Coding), SBC (Sub-band coding, sub-band coding) etc..It is being by PCM document No.
When by the file of Bluetooth transmission, encoding rate is higher, i.e., the coding of higher code rate, and the data after coding are bigger；Encoding rate

Or when being equal to default electricity, then the mode for turning down audio data coding rate can be, and the encoding rate of audio data can be adjusted
To less than preset threshold.
Wherein, which, which can be, is arranged by system and is stored, and is also possible to by user setting.User setting can be with
It is to be arranged under set interface in advance, is also possible to user and is configured or changes currently.For example, default being provided with
In the case where threshold value, the encoding rate of audio data is adjusted to the encoding rate less than preset threshold, if being transferred to bluetooth headset
Audio data normal play, user think low battery of the sound quality without influence or bluetooth headset, and user can be again by default threshold
Value is turned down.If the audio data for being transferred to bluetooth headset plays, sound quality loss is excessive, and user can also be appropriate by preset threshold
It is turned up.To which user can turn down and be turned up operation by result of broadcast combination preset threshold, and searching out one makes audio
The encoding rate that data point reuse arrives is as small as possible and influences on the sound quality of audio data as unobvious as possible.
Step S130: after the audio data is handled according to encoding rate adjusted, it is transmitted to the bluetooth headset.
Electronic equipment is handled audio data according to the encoding rate adjusted.Specifically, can be according to the coding
Rate is encoded to be sent to the audio data of bluetooth recently by bluetooth, and the audio data after coding is passed through bluetooth mould
Block is transmitted to bluetooth headset in a manner of Bluetooth transmission.
For example, electronic equipment plays out the corresponding music of MP3 music file by bluetooth headset.By mp3 file
It is decoded as PCM file, then the PCM document No. can be passed through the coding text of Bluetooth transmission by the encoding rate by adjusting after
The coding file is passed through Bluetooth transmission to bluetooth headset by part.After bluetooth headset receives the coding file, to the coding file
It is played after decoding.
In the embodiment of the present application, it is adjusted according to the electricity for the bluetooth headset for being connected to electronic equipment to bluetooth headset and is transmitted
The encoding rate of audio data the encoding rate of audio data is adjusted to default threshold when electricity is less than or equal to default electricity
Value, by after audio data coding, to be sent to bluetooth headset by preset threshold.So that the data volume that bluetooth headset receives is more
Small, data volume to be treated is then smaller, to realize the saving of electrical quantity of bluetooth headset.
Encoding rate method of adjustment provided by the embodiments of the present application is then obtained when electronic equipment is connected to a bluetooth headset
The electricity for this earphone that the electricity for the bluetooth headset got is attached to, the electricity for determining the earphone are less than preset threshold
