Audio sharing method and device

The embodiment of the invention provides an audio sharing method and device, and relates to the technical field of communication, in the method, an audio source device shares a first group identity analysis key corresponding to a first device group to a shared audio device, and the shared audio device sets the group identity analysis key of each shared playing device as a first group identity analysis key. Each shared playing device joins in a first device group based on a first group of identity analysis keys, then establishes a connection-based synchronous data stream with the audio source device, receives audio data shared by the audio source device, and obtains the control capability of the audio source device and the capability of sending data to the audio source device at the same time; therefore, the audio sharing effect and universality are improved. And secondly, compared with broadcast stream sharing, when the connection-based synchronous data stream is adopted to share the audio data, the delay can
