B2 and B3 respectively indicates different encoding rates.According to default mapping table, search the signal strength it is corresponding be greater than or
It is the target code rate equal to the encoding rate of preset threshold.That is, obtain electronic equipment and audio-frequence player device it
Between bluetooth signal strength after, the corresponding signal strength A of the signal strength in default mapping table is searched, with signal strength
The corresponding encoding rate B of A is as the corresponding target code rate of the signal strength.
In addition, signal strength can be a specific value, and it is strong to be also possible to a signal in default mapping table
Spend section.Such as A1, A2 and A3 can be respectively different intensity values in Fig. 4, can also be respectively different intensity intervals.
If signal strength is a specific value in default mapping table, acquisition electronic equipment and the audio-frequence player device it
Between bluetooth signal intensity after, it is strong the signal most solved with the signal strength size can be searched in default mapping table
Degree.If signal strength is a section in default mapping table, obtaining between electronic equipment and the audio-frequence player device
Bluetooth signal intensity after, the section where the signal strength being searched in default mapping table.
As an implementation, it can be, pre-establish and be stored with the pass of the function between signal strength and encoding rate
System is strong according to the signal in the case where detecting the bluetooth signal intensity between electronic equipment and the audio-frequence player device
Degree and the functional relation of storage, calculate the corresponding encoding rate of the signal strength, as target code rate.
Step S240: the encoding rate of the audio data is adjusted to the target code rate more than or equal to preset threshold.
Step S250: after handling the audio data according to the target code rate, the audio data is passed through described
Bluetooth module is transmitted to the audio-frequence player device.
It is corresponding with signal strength and be greater than or equal to pre- by this is adjusted to the encoding rate that audio data encodes
If the target code rate of threshold value.When being encoded audio data, encoded with the target code rate, by audio data
Being encoded to can be by the coding file of Bluetooth transmission, and meets the transmittability under current signal strength, so as to be transferred to
The coding file of audio-frequence player device does not generate Caton when audio-frequence player device is decoded and played, and under current signal strength
The best sound quality that can be obtained.
In this step, in the case where WiFi module is not in working condition, with it is corresponding with signal strength, be greater than or
Target code rate equal to preset threshold uses up audio data to realize coding rate audio data as high as possible
In the case where sound quality that may be good, broadcasting not Caton of the corresponding music of audio data in audio-frequence player device.
In the present embodiment, it can determine that target is compiled according to the bluetooth signal intensity between electronic equipment and audio-frequence player device
Code rate, with more meet the target code rate of current signal strength to audio data carry out coded transmission to audio-frequence player device into
Row plays, and obtains and preferably plays sound quality.
In the embodiment of the present application, more than or equal to the encoding rate more than one of preset threshold, due to different types of sound
Frequency evidence, continuity and sound quality to transmission require may be different, in the case where WiFi module is not in working condition, mesh
Mark encoding rate is specifically adjusted to how much can also determine according to the data type of audio data.Specifically, Fig. 5 is referred to, the party
