Patent ID: 8380131

Claim:
A frequency selection system comprising: a wireless microphone including a microphone element for receiving sound and outputting a corresponding audio signal, and a transceiver device electrically coupled to said microphone element for wireless transmission of the audio signal and configuration communication, said transceiver device having a first communication unit operable to receive a frequency code, a wireless transmission unit operable to wirelessly transmit the audio signal received from said microphone element using a wireless transmission frequency that corresponds to the frequency code received by said first communication unit, a first microprocessor operable to wirelessly send a command code through said first communication unit, to receive the frequency code through said first communication unit, and to drive said wireless transmission unit such that the wireless transmission frequency used thereby to transmit the audio signal corresponds to the frequency code received from said first communication unit, and a first operable part that is operable to drive said first microprocessor to send the command code and to receive the frequency code; and a receiver that includes a second communication unit for wirelessly receiving the command code from said first communication unit and wirelessly sending the frequency code to said first communication unit, a receiving unit for wirelessly receiving the audio signal transmitted from said wireless transmission unit using the wireless transmission frequency corresponding to the frequency code, a frequency selection unit for selecting the wireless transmission frequency, said frequency selection unit being drivable to control said wireless receiving unit to use the selected wireless transmission frequency to receive the audio signal, and a second microprocessor for driving said frequency selection unit to select the wireless transmission frequency in response to receipt of the command code received by said second communication unit from said first communication unit, for generating the frequency code in such a manner that the frequency code corresponds to the selected wireless transmission frequency, and for sending the frequency code to said first communication unit through said second communication unit.
