Abstract: In a wireless microphone system, a master device includes a master device control unit that generates a communication table in which a pair of a carrier wave and a slot which are used for communication with m microphone slave devices are set for one frame period, based on a total number of six carrier waves in a DECT system and n slots constituting one frame period of the DECT system, and k wireless processing units that perform communication using the DECT system with corresponding individual microphone slave devices among m microphone slave devices, based on the generated communication table. The k wireless processing units respectively operate synchronously based on the same clock signal.

Abstract: A sound amplification apparatus includes one or more microphones that convert collected sound into an audio signal and transmit the audio signal by radio and a sound receiving apparatus that receives the audio signal transmitted from the microphone and amplifies and outputs the sound based on the audio signal. The sound receiving apparatus is configured to perform sound output control in an emergency mode upon receiving an emergency signal transmitted in response to operation of an emergency switch of the microphone. With this configuration, it is possible to perform appropriate sound control in a dangerous situation such as intrusion of a suspicious person.

Abstract: One of the plurality of first slave receiving apparatuses which serves as a reference first slave receiving apparatus repeatedly transmits a wireless control signal for controlling synchronization between a first receiving apparatus segment and a second receiving apparatus segment. One of the plurality of second slave receiving apparatuses which serves as a reference second slave receiving apparatus transmits a reference timing signal for performing synchronization in the second receiving apparatus segment including the reference second slave receiving apparatus to the second master receiving apparatus in synchronization with the wireless control signal. The second master receiving apparatus transmits a synchronization timing signal for performing synchronization in the second receiving apparatus segment including the second master receiving apparatus to another one of the plurality of second slave receiving apparatuses in the second receiving apparatus segment including the second master receiving apparatus, in response to the reference timing signal.

Abstract: A wireless microphone system includes: an input device; and a receiver including a processor and a memory storing instructions that, when executed by the processor, cause the receive to perform operations. The operations include: wirelessly communicating with at least one of wireless microphones capable of collecting voices of respective speaking persons and wirelessly transmitting voice signals of the respective voices; receiving a voice signal of a speaking person transmitted from a corresponding one of the wireless microphones; holding voice channel management data generated based on input from the input device and defining a use relationship between voice channels and the wireless microphones, respectively; and audibly outputting the voice signal of the speaking person sent from the corresponding one of the wireless microphones by using, based on the voice channel management data, any one of the voice channels.
