AUDIO DATA SYNCHRONIZATION METHOD AND DEVICE

WIPO Patent Application WO/2020/133183

A1

Disclosed are an audio data synchronization method and device, which relate to the field of short-distance communications. When a wireless connection is established between a mobile phone and a plurality of Bluetooth devices, play-level synchronization of audio data between the plurality of Bluetooth devices is realized. The method comprises: an electronic device sending, by means of a first CIS of a CIG, a data packet to a first earbud that establishes a wireless connection with the electronic device, and sending, by means of a second CIS of the CIG, the data packet to a second earbud that establishes a wireless connection with the electronic device, wherein the data packet comprises: audio data, an audio timestamp of the data packet and an initial Bluetooth timestamp; the initial Bluetooth timestamp is a Bluetooth timestamp of a first data packet transmitted after the electronic device establishes the first CIS with the first earbud and establishes the second CIS with the second earbud; the audio timestamp and the initial Bluetooth timestamp are used for the first earbud and the second earbud to determine a CIG play point; and the CIG play point is a time point at which the first earbud and the second earbud play the audio data.
