That is to say, when audio data needs to be shared to a plurality of audio playing devices, only the first audio playing device needs to share link information to the second audio playing device, and connection between the second audio playing device and the terminal device does not need to be specially established. Compared with the prior art that the connection between the terminal equipment and the plurality of audio playing equipment is established by depending on the terminal equipment, and the audio playing equipment is respectively sent to the plurality of audio playing equipment through a plurality of paths, the method and the device do not need a user to operate on the terminal equipment side, and can reduce the power consumption of the terminal equipment.

In some embodiments, a trigger instruction may be input through a physical key or a virtual control on the first audio playback device to start an information synchronization function of the first audio playback device, so that the first audio playback device enters an information synchronization state. Similarly, a trigger instruction may also be input through a physical key or a virtual control on the second audio playing device to start the information synchronization function of the second audio playing device, so that the second audio playing device enters an information synchronization state.
In some optional embodiments, the number of the second audio playing devices may be multiple, when the number of the second audio playing devices is multiple, the information synchronization functions of the multiple second audio playing devices may be simultaneously turned on, or only part of the information synchronization functions of the second audio playing devices may be turned on, and in the implementation process, the information synchronization function of the corresponding second audio playing device may be turned on as needed.
In the embodiment of the present disclosure, after the information synchronization functions of the first audio playing device and the second audio playing device are both turned on, the first audio playing device starts broadcasting the link information again. Therefore, the possibility that the first audio playing device broadcasts the link information when the first audio playing device is unnecessary can be reduced, and the power consumption of the first audio playing device is further reduced.
In some optional embodiments, the broadcasting the link information when the information synchronization function of the first audio playing device and the information synchronization function of the second audio playing device are both turned on includes:

and broadcasting the link information when detecting that a second audio playing device which starts the information synchronization function exists in the preset range.
Here, the first trigger instruction may be input based on a physical key of the first audio playing device, for example, the first key may be provided on the first audio playing device, and the first trigger instruction may be input by pressing the first key for a long time, so as to start the information synchronization function of the first audio playing device. In other embodiments, the first trigger instruction may also be input by clicking the first key, for example, by clicking, double clicking, or the like the first key.

In the embodiment of the disclosure, when the set duration is exceeded, the first audio playing device is controlled to exit the synchronization state, and the broadcast link information is stopped, so that compared with a continuous detection operation, the power consumption of the first audio playing device can be reduced.
Since the first audio playing device and the second audio playing device are both short-distance communication devices, in the embodiment of the disclosure, after the information synchronization functions of the first audio playing device and the second audio playing device are both turned on, the first audio playing device does not directly broadcast the link information, but further determines whether the second audio playing device is within a preset range, and when the second audio playing device is within the preset range, the first audio playing device starts to broadcast the link information again. Therefore, the possibility that the first audio playing device broadcasts the link information when the first audio playing device is unnecessary can be reduced, and the power consumption of the first audio playing device is further reduced.

In an example scenario, if a first audio playing device is in a process of establishing a wireless communication connection with a terminal device and the terminal device is broadcasting an air audio, the first audio playing device may obtain link information between the first audio playing device and the terminal device in real time to obtain latest link information, and share the link information obtained in real time to a second audio playing device.
In another exemplary scenario, after the first audio playback device establishes a wireless communication connection with the terminal device, link information with the terminal device may be acquired and added to the historical link information list. Therefore, when the first audio playing device needs to share the link information with the second audio playing device, the link information corresponding to the terminal device can be directly obtained from the historical link information list, and the link information is broadcasted, so that the information interaction speed and efficiency can be improved.
In some optional embodiments, the link information includes: a link key; the link key is used for:

In some alternative embodiments, the over-the-air audio to be broadcast may be encrypted directly using the link key. In other alternative embodiments, a temporary Encryption Key (Encryption Key) may also be generated based on a random number exchanged by the link Key before the link Key communicates with the first audio playing device and the terminal device, and the air audio to be broadcast is encrypted by the temporary Encryption Key. Wherein the temporary encryption key may be used to encrypt data in both directions.
When the over-the-air audio to be broadcast is a temporary encryption key, the temporary encryption key may be added to the link information and the link information with the temporary encryption key may be broadcast.
In other embodiments, when the link keys of the first audio playing device and the terminal device are matched, it indicates that the first audio playing device is an authentication device of the terminal device, where the link keys of the first audio playing device and the terminal device are matched, including: the link keys of the first audio playing device and the terminal device are the same.
