Abstract
Various embodiments provide a Bluetooth-based playback method and an electronic device. In those embodiments, a first processor copies a coding algorithm, a sound effect postprocessing program, and a Bluetooth audio transmission protocol to a second processor, transmits first to-be-decoded data to the second processor, and enters a sleep state. The second processor receives the first to-be-decoded data, performs decoding, sound effect post-processing, and coding on the first to-be-decoded data to obtain first coded data, and sends the first coded data to a Bluetooth module using a third processor. The Bluetooth module converts the first coded data into a first wireless signal, and sends the first wireless signal to an external playback device to implement audio playback. 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.
