Abstract: The method for processing data of Bluetooth speaker includes: running a first program firmware before the Bluetooth speaker is awakened; awakening the Bluetooth speaker after detecting wake-up information by the first program firmware, and caching received speech data by the first program firmware; establishing connection with a terminal device, and transmitting the speech data to the terminal device; and switching from the first program firmware to the second program firmware for operation if a request for re-establishing connection from the terminal device is received after current connection with the terminal device is disconnected, and receiving speech data fed back by the terminal device through the second program firmware, and playing the speech data fed back by the terminal device. The present application can increase the space for storing speech data when the size of the storage space of a system is fixed, thereby caching more speech data.

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.
