Multi-channel speaker system and a connection system thereof

A multi-channel speaker system comprising:

• a plurality of speakers;
• a main audio body with an analog audio signal generating circuit that is configured to generate a plurality of analog signals for operating the plurality of speakers;
• a serial audio signal circuit configured to generate a single serial digital audio signal by synthesizing the plurality of analog signals that are generated by the analog audio signal generating circuit;
• and
• a plurality of audio signal separating circuits, a number of which corresponds to a number of the plurality of speakers, the audio signal separating circuit receiving the serial digital audio signal generated by the serial audio signal circuit and separating a corresponding digital signal, and the audio signal separating circuit converting the separated digital signal to an analog signal,
• wherein the serial audio signal circuit comprises
• an analog/digital converter for receiving the plurality of analog signals from the audio signal generating circuit and converting the analog signals respectively to digital signals,
• a multi-channel control signal synthesizer for synthesizing the digital signals into a single digital signal,
• a clock generator for providing a respective reference clock for the synthesized digital signal,
• a digital signal synthesizer for synchronizing each of the digital signals in response to the reference clock generated by the clock generator, and
• a serial signal outputting member for converting the synchronized digital signal to a serial digital audio signal,
• and wherein the audio signal separating circuit comprises
• a multi-channel separator SD for separating a digital signal corresponding to the respective speaker from the serial digital audio signal input through a wire, and
• a digital/analog converter for converting the separated digital signal to an analog signal.
