Abstract: A microphone head device includes a microphone head, a mount and a vibration-absorbing unit. The mount includes amount ring surrounding the microphone head, and a plurality of annularly spaced-apart support rods projecting axially from the mount ring. The vibration-absorbing unit includes a surrounding body sleeved fittingly on the microphone head and having one end inserted between the microphone head and the mount ring, and a plurality of annularly spaced-apart hollow posts connected to the surrounding body and sleeved respectively on the hollow posts.

Abstract: A frequency selection system includes a wireless microphone and a receiver. The wireless microphone includes a microphone element for receiving sound and outputting a corresponding audio signal, and a transceiver device electrically coupled to the microphone element for wireless transmission of the audio signal and configuration communication. The transceiver device has a first communication unit operable to receive a frequency code. The transceiver device also includes a wireless transmission unit operable to wirelessly transmit the audio signal received from the microphone element using a wireless transmission frequency that corresponds to the frequency code received by the first communication unit. The receiver includes a second communication unit for wirelessly receiving a command code from the first communication unit and wirelessly sending the frequency code to the first communication unit.
