Description

technical field [0001] The invention relates to a voice broadcasting system, and mainly relates to an interactive network voice broadcasting system. Background technique [0002] Traditional campus broadcasts generally use audio or FM. Audio broadcasting is affected by factors such as voltage, power, impedance, etc., the transmission distance is short, the frequency is low, it is easy to be interfered, the system expandability is poor, the cost of cable layout is high, and it also affects the beauty of the building. Aging and frequency shift can also cause signal distortion. The controllable intelligent broadcast based on audio and FM transmission is limited by the transmission method, and can only be controlled in a partitioned and grouped manner. At the same time, due to the lack of an independent program source, the broadcast terminal cannot meet the individualized teaching application requirements. Today, when language teaching tends to be more practical, it is requir...
