Abstract
An audio data communication method and a wireless audio system are disclosed. The audio data communication method is performed by dual-channel wireless audio equipment that includes a primary audio device, a secondary audio device, and a communication link with an audio source device. The method includes transmitting, by the source device, audio data in a preset time interval to the primary and secondary audio devices. The primary and secondary audio devices generate first feedback information and second feedback information. The first and second feedback information are transmitted to the audio source device based on a Carrier Sense Multiple Access/Collision Avoidance protocol. The disclosed techniques address issues such as information interaction between the primary and secondary audio devices during transmission of the feedback information.
