Abstract
The present disclosure is applicable to the technical field of loudspeaker and provides a method and apparatus for reducing continuous-wakeup delay of Bluetooth loudspeaker and a Bluetooth loudspeaker. The method for reducing continuous-wakeup delay of Bluetooth loudspeaker includes: resetting a wakeup flag bit to wait for a next wakeup when receiving a stop-recording instruction which is sent by a terminal equipment through a Bluetooth serial port communication protocol; and executing a wakeup-interruption operation again after a preset wakeup keyword is received. According to the present disclosure, time delay under a continuous-wakeup mode can be greatly reduced and a response speed of continuous-wakeup can be improved.
