Audio transmission method and audio playback system

Abstract

The present invention provides an audio transmission method, which includes the following steps: a special switching device respectively marks a certain audio data with an identifier 1, an identifier 2, ..., an identifier N, and alternately marks the audio data with an identifier 1, an identifier 2,..., an identifier The audio data of N is repeatedly sent to the first playback device, the second playback device, ..., the Nth playback device; when the first playback device receives the audio data with the identifier 1, it returns an ACK data to the dedicated switching device packet; when the second playback device receives the audio data with the identifier 2, it returns an ACK data packet to the dedicated transfer device, ..., when the Nth playback device receives the audio data with the identifier N, it returns an ACK packet to the dedicated transfer device Return an ACK packet, where N≥2. The audio transmission method of the present invention can effectively reduce the delay of different playback devices, and realize low-delay communication between the smart device and the playback device.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an audio transmission method and an audio playback system. Background technique [0002] With the progress of society and the improvement of people's living standards, people pursue wireless life, and wireless multi-speaker systems have become people's daily necessities. Wireless speaker equipment gets rid of the shackles of wires, and realizes true wireless connection between different speakers. It has the advantages of flexibility and convenience, and different speakers can play in different spaces. [0003] However, in the prior art, wireless multi-speakers are still connected through Bluetooth, and it is difficult to realize an effective connection between speakers with large spans. Moreover, forwarding audio in the form of Bluetooth broadcasting is prone to errors in forwarding data. The audio received by the speaker device has the disadvantages of large dela...

AI Technical Summary

Problems solved by technology

[0003] However, in the prior art, wireless multi-speakers are still connected through Bluetooth, and it is difficult to realize an effective connection between speakers with a large span.

In addition, the audio is forwarded in the form of Bluetooth broadcasting, and the forwarding data is prone to errors. The audio received by the speaker device has a large delay and Bluetooth interference, which can easily lead to a sense of stuttering, and the reliability of the connection between multiple speakers is poor.

[0004] Therefore, in order to solve the problem of large time delay between wireless speakers in the prior art, an audio transmission method and an audio playback system are needed
