In addition, there are many wireless speakers in the market. Wireless speakers include WIFI wireless speakers, 2.4G / 5G wireless speakers and Bluetooth speakers according to wireless communication methods. However, it is difficult to integrate the above-mentioned advanced audio and video players and wireless speakers to form a complete stereo playback. system

[0003] The existing Chinese patent with the application number 201110392079.3 discloses a wireless network audio system. By setting two speakers to achieve the effect of 2.0 stereo channels, it provides users with a wireless network audio system with a perfect stereo listening experience. However, the wireless network The sound system has limited functions, does not support 5.1-channel and 7.1-channel, and does not support HDMI audio input processing, which is poor in flexibility and cannot meet people's higher demand for stereo playback
