Abstract: An audio synchronization playback method includes: obtaining, by the primary playback device, target audio data; sending, by the primary playback device, the target audio data to at least one secondary playback device for playback; synchronizing, by the primary playback device, local time of the primary playback device with local time of the reference clock device based on a target audio synchronization signal in response to receiving the target audio synchronization signal and obtaining, by the primary playback device, reference playback timestamp of the target audio synchronization signal; where the target audio synchronization signal is a periodic signal sent by the reference clock device, and the reference clock device is the primary playback device or one secondary playback device of the preset quantity of secondary playback devices; and starting, by the primary playback device, playback from a target audio data frame corresponding to the reference playback timestamp.
