Abstract
A bidirectional microphone system is disclosed, including a base station, a wireless microphone and an external control device. A bidirectional wireless communication may be performed between the wireless microphone and the base station. The external control device is connected to the wireless microphone for controlling the wireless microphone via at least one push button on the external control device. The external control device is also provided with light-emitting elements to show the function or status of the wireless microphone. The wireless microphone is provided with a global positioning system or a G-sensor for locating the coordinates of the wireless microphone under different situations. When the wireless microphone is in an emergency and located beyond the wireless communication range, the wireless microphone emits a high-power pulsed radio frequency signal for antenna of the base station to locate the position of the wireless microphone.
