Summary of Multi Zone Audio Technology

The zone selector connects the audio source through the audio interface and the control interface, uses the coaxial line as the transmission line through the interface module of the central control terminal, and uses the star-shaped topology structure to connect the main speakers of each terminal separately.

The zone selector discloses an audio playback system based on regional distributed speakers, which include audio source and audio control equipment at the central control terminal, main speaker and multiple speakers at the terminal. Zone selector equipment connects audio source through audio interface and control interface, and connects each audio source through coaxial line through the interface module of the central control terminal, using star-shaped topology structure to connect each audio source separately. There are three main speakers located at the terminal, the main speaker connects multiple sub-speakers to form multi-channel audio playback equipment, and the coaxial line transmits three kinds of signals, namely, audio, control and power. The invention has the advantages of easy construction, multi-channel audio playback, good sound quality, good user experience, stable transmission of audio data stream, strong anti-interference, and avoiding the influence of signal jitter on sound quality, and has broad application prospects.
