Abstract

The embodiment of the invention provides a prompt message synchronization method which is applied to a TWS Bluetooth headset. The method comprises the steps of when a master headset receives prompt messages sent by sound source equipment, based on a first moment when the prompt messages are received, clock offset and jitter information between the master headset and a slave headset, and preset preparation duration when the slave headset plays the prompt messages, a first playing moment is determined; the master handset sends a prompt information packet to the slave handset, the prompt information packet comprises the prompt information and playing time indication information, wherein the playing time indication information is used for indicating the slave handset to play the prompt information at the first playing time; and the master handset determines a second playing moment based on the first playing moment and the clock offset between the master handset and the slave handset, and plays the prompt information at the second playing moment. According to the embodiment of the invention, the master handset and the slave handset can play the prompt information at the same time point, and it is guaranteed that the prompt information output between the master handset and the slave handset can be kept synchronous.

Description

technical field [0001] The embodiments of the present application relate to the technical field of bluetooth earphones, and in particular to a method and device for synchronizing prompt information. Background technique [0002] Due to its true wireless structure, the True Wireless Stereo (TWS for short) Bluetooth headset completely abandons the trouble of wiring and has various ways of use, and has become more and more popular among users. [0003] During the use of the audio source device, it is generally accompanied by some specific prompt information, so that the user can accurately grasp its working status. After the TWS Bluetooth headset is wirelessly connected to the audio source device, the prompting methods of the above prompt information usually include single-ear prompting and binaural prompting. [0004] Among them, in the single-ear prompt mode, only the main earphone of the TWS Bluetooth headset outputs the prompt sound, so the stereo effect cannot be achieved...
