摘要
PURPOSE: The system for a digital wireless microphone, a simultaneous interpretation, and a conference is provided to enable the communication without a noise and an interference between the microphone for a transmission part and the receiver for a reception part, to offer the communication via several channels in the same area, by making an existing wired system wireless. CONSTITUTION: A microphone device(100) includes a control circuit(101), a frequency synthesizer(102) for modulating the transmission signal inputted via a microphone and the data output from the control circuit(101), and a transmission circuit(103) for sending out the signal modulated by the frequency synthesizer(102) as a radio signal with a band of 900MHz. An interpreter microphone device(200) includes a control circuit(201), a receiver circuit(202), a frequency synthesizer(203) and a transmitter circuit(204). A wireless microphone receiver(300) includes a receiver circuit(301), a control circuit(302), a frequency synthesizer(303), and an interface part(304) for communicating with an audio output device(500). An interpreter receiver(400) includes a receiver circuit(401), a frequency synthesizer(402) and a control circuit(403).
