Bluetooth-based playback method and electronic device

An electronic device, wherein the electronic device comprises a first processor, a second processor, a third processor, and a Bluetooth module, the first processor is communicatively connected to the second processor, the second processor is communicatively connected to the third processor, and the third processor is communicatively connected to the Bluetooth module, wherein

• the first processor is configured to copy a coding algorithm, a sound effect post-processing program, and a Bluetooth audio transmission protocol to the second processor;
• the first processor is configured to transmit first to-be-decoded data to the second processor, wherein the first to-be-decoded data is to-be-played audio data;
• the first processor is configured to enter a sleep state;
• the second processor is configured to:
• receive the first to-be-decoded data transmitted by the first processor, and perform decoding, sound effect post-processing, and coding on the first to-be-decoded data to obtain first coded data;
• the second processor is configured to send the first coded data to the Bluetooth module using the third processor;
• and
• the Bluetooth module is configured to:
• convert the first coded data into a first wireless signal, and send the first wireless signal to an external playback device of the electronic device to implement audio playback, wherein
• the electronic device is communicatively connected to the playback device over Bluetooth;
• wherein after the first processor enters a sleep state,
• the first processor is configured to receive a signal indicating that the electronic device receives an incoming call request;
• the first processor is configured to be woken up;
• the first processor is configured to:
• stop audio playback, and retain current audio playback data;
• and
• the first processor is configured to switch to a call voice program.

A non-transitory computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable medium and that, when executed by a processor, are configured to cause an electronic device to:

• copy, by a first processor, a coding algorithm, a sound effect post-processing program, and a Bluetooth audio transmission protocol to a second processor, wherein the electronic device comprises the first processor, the second processor, a third processor, and a Bluetooth module;
• transmit, by the first processor, first to-be-decoded data to the second processor, wherein the first to-be-decoded data is to-be-played audio data;
• enter, by the first processor, a sleep state;
• receive, by the second processor, the first to-be-decoded data transmitted by the first processor, and performing decoding, sound effect post-processing, and coding on the first to-be-decoded data to obtain first coded data;
• send, by the second processor, the first coded data to the Bluetooth module using the third processor;
• and
• convert, by the Bluetooth module, the first coded data into a first wireless signal, and sending the first wireless signal to an external playback device of the electronic device to implement audio playback, wherein the electronic device is communicatively connected to the playback device over Bluetooth;
• wherein after entering, by the first processor, the sleep state, the computer-executable instructions are configured to further cause the electronic device:
• receive, by the first processor, a signal indicating that the electronic device receives an incoming call request;
• wake up the first processor;
• stop, by the first processor, audio playback, and retaining current audio playback data;
• and
• switch to, by the first processor, a call voice program.
