Step 207, the first voice data is transmitted to mobile terminal by Bluetooth chip by Bluetooth protocol.
The first voice data received is transmitted to mobile terminal by Bluetooth chip by Bluetooth protocol, eventually by movement
First voice data is transmitted to opposite end by the communication protocol of terminal.
Step 208, second audio data is transmitted to Bluetooth chip by mobile terminal by Bluetooth protocol.
When mobile terminal receives the second audio data of opposite end transmission, the second sound for will being received by Bluetooth protocol
Frequency evidence is transmitted to Bluetooth chip.
Step 209, the second transmission link is established, second audio data is sent to CPU via digital processing chip.
After Bluetooth chip receives the second audio data of mobile terminal transmission, second audio data is transmitted as it
Connected digital processing chip.
Digital processing chip establishes the second transmission link after handling second audio data, that is, establishes audio recording
Second audio data is transmitted to universal cpu processor by link.
Step 210, amplitude modulation processing is carried out to second audio data.
Since environment inside car is more noisy in driving conditions, amplitude modulation processing is carried out to the second audio data received, is made
Second audio data is played in playing process with being more than the volume of some threshold value.
Step 211, second audio data is sent to audio player by USB interface to play out
The second audio data received is transmitted to USB interface, is transmitted second audio data by USB transport protocol
To audio player, the voice data of opposite end transmission is passed through audio player plays by final realize.
The transmission method of voice data provided by the embodiments of the present application is gathered by receiving audio collection device and passes through USB
The first voice data that interface transmits；After echo cancellor and noise reduction process is carried out to the first voice data, audio is established
Link is played, the first voice data is sent to Bluetooth chip by digital processing chip, so that Bluetooth chip is led to by bluetooth
First voice data is transferred to mobile terminal by letter technology；By establishing audio recording transmission link, Bluetooth chip is sent
Second audio data is transmitted to CPU by digital processing chip, and sends the second audio data eventually by USB interface
It is played out to audio player.Using this programme, it can be achieved that pluggable Portable Bluetooth car kit phone, adds the choosing of user
Selecting property enhances the security of user's driving while driving communication quality is improved.
