Abstract
A user terminal, a method for playing audio data via Bluetooth, and a digital signal processor are provided. The method includes: a digital signal processor receiving a basic packed data template from an application processor; a SBC module coding audio source data to obtain the audio data packet; the digital signal processor implementing a data packing to the audio data packet based on the basic packed data template, to obtain a packed audio data packet; the digital signal processor implementing dividing and packing to the packed audio data packet to obtain a data packet to be sent; and the digital signal processor sending the data packet requested to be sent to a Bluetooth controller via a PCM interface between the digital signal processor and the Bluetooth controller. Accordingly, the digital signal processor instead of the application processor is employed to achieve audio play, thus reducing power consumption.
