1. A Bluetooth speaker control method, applicable to a mobile terminal, wherein the Bluetooth speaker control method comprises following steps:
acquiring an audio information;
parsing the audio information;
constructing multiple sound channels through an audio manager in a system framework of the mobile terminal;
constructing multiple virtual Bluetooth audio transmission model protocol channels through a Bluetooth protocol stack of the mobile terminal;
correspondingly connecting the virtual Bluetooth audio transmission model protocol channels with multiple external Bluetooth speakers;
transmitting parsed audio information to the multiple sound channels in the audio manager;
playing the audio information in the multiple sound channels through the multiple external Bluetooth speakers;
directly measuring and adjusting a delay time on the mobile terminal by virtually creating a corresponding number of A2DP protocol channels through the Bluetooth protocol stack to connect with the multiple external Bluetooth speakers; and
conducting audio playback tests for the multiple external Bluetooth speakers individually, and using a microphone of the mobile terminal to capture sound and obtain a corresponding delay time for the multiple external Bluetooth speakers.
