Problems solved by technology

[0004] However, the above-mentioned audio playback device has at least the following disadvantages: the audio playback device must communicate with the operating system of the host through the host connector for data transmission, and if data transmission needs to be performed between two or more audio playback devices, it must be transmitted through The host connector and the host can be completed, so it is separated from the host connector, the host and the operating system to directly realize the data transmission between two or more audio playback devices, which is inconvenient to use
