Problems solved by technology

Since the audio source device can only receive feedback information from one audio device, an additional link is usually established between the master audio device and the slave audio device, and one of the audio devices sends the feedback information agreed by both parties to the audio source device, but The above approach makes information exchange and operation complex between the master audio device and the slave audio device

Abstract

The invention discloses an audio data communication method and a wireless audio system. The audio data communication method is applied to a dual-track wireless audio device, the dual-track wireless audio device comprises a master audio device and a slave audio device, and a communication link is arranged between the master audio device and a sound source device; the audio data communication method comprises the following steps: a sound source device sends audio data in a preset time period; the main audio equipment and the slave audio equipment respectively receive audio data; according to the receiving condition of the audio data, the master audio device and the slave audio device generate first feedback information and second feedback information respectively; and based on a carrier sense multiple access (CSMA)/CA protocol with collision avoidance, the master audio device sends the first feedback information to the sound source device, or the slave audio device sends the second feedback information to the sound source device. According to the invention, the problems of information interaction and complex operation between the main audio equipment and the slave audio equipment when the feedback information is sent in the prior art can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an audio data communication method and system. Background technique [0002] With the increasing maturity of Bluetooth communication technology, audio equipment (including speakers, earphones, etc.) has achieved rapid development from wired to wireless. Among them, the wireless audio equipment with two channels of left and right not only has the advantages of wireless connection and portability, but also can provide a three-dimensional and full sound field effect, which is deeply loved by people and has been more and more widely used. [0003] Due to the characteristics of Bluetooth Piconet, the point-to-point communication mechanism is mainly used between devices; in order to ensure that the two audio devices (one master and one slave) in the two-channel wireless audio device can receive the audio data sent by the audio source device, the commonly used methods are ...
