Audio transmission method and audio playing system

Abstract

The invention provides an audio transmission method, which comprises the following steps that: a special switching device respectively marks an identifier 1, an identifier 2,... and an identifier N for certain audio data, and repeatedly sends the audio data with the identifiers 1, 2,... and N to a first playing device, a second playing device,... and an Nth playing device in turn; when the first playing device receives the audio data with the identifier 1, an ACK data packet is returned to the special switching device; and when the second playing device receives the audio data with the identifier 2, an ACK data packet is returned to the special switching device,..., when the Nth playing device receives the audio data with the identifier N, an ACK data packet is returned to the special switching device, and N is greater than or equal to 2. According to the audio transmission method, the delay of different playing devices can be effectively reduced, and low-delay communication between the intelligent device and the playing device is realized.

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
