Multimedia system

The invention provides a multimedia system. The multimedia system comprises a plurality of transmission devices and a receiving end device. Each of the plurality of transmission devices has a microphone. The receiving end device is coupled to a plurality of transmission devices. When the microphone of one of the plurality of transmission devices is enabled, the receiving end device outputs at least one control signal to at least another one of the plurality of transmission devices so as to disable the microphone of at least another one of the plurality of transmission devices. 本发明提出一种多媒体系统。多媒体系统包括多个传输设备以及接收端装置。多个传输设备分别具有麦克风。接收端装置耦接多个传输设备。当多个传输设备的其中一个的麦克风被致能时，接收端装置输出至少一控制信号至多个传输设备的至少其中另一个，以禁能多个传输设备的至少其中另一个的麦克风。
