Abstract: A microphone head device includes a base unit, a microphone head unit and a connecting rod unit. The microphone head unit is disposed on the base unit, and includes a microphone head seat and a dynamic subunit mounted on the microphone head seat. The dynamic subunit includes a mounting seat, a first magnetic member disposed on the mounting seat, a coil surrounding the first magnetic member, and a vibrating plate disposed over the first magnetic member and connected to the coil. The connecting rod unit extends in an up-down direction through the first magnetic member, the mounting seat and the microphone head seat such that the first magnetic member, the mounting seat and the microphone head set are separably secured.

Abstract: A microphone includes a main body surrounding a longitudinal axis that extends in a top-bottom direction, a battery holder mounted to the main body, and a protective cover. The protective cover has a cover body pivotally connected to and openably covering the battery holder for retaining a battery therein, and a positioning unit connected to the cover body. The protective cover is pivotable about a pivot axis transverse to the top-bottom direction to turn upward and downward and to move between a closed position, where the positioning unit engages the battery holder, and an opened position, where the positioning unit is disengaged from the battery holder in a direction transverse to the top-bottom direction.

Abstract: A wireless microphone system includes a microphone and a receiver. The microphone converts sound into audio data, and wirelessly transmits a carrier signal that contains the audio data via a microphone channel. The receiver receives the carrier signal via a receiver channel that matches the microphone channel, and automatically and repeatedly sweeps a plurality of wireless channels. The receiver selects at least one wireless channel that is free of interference to serve as a communication channel, transmits to the microphone a channel switching instruction for causing the microphone to set the communication channel as the microphone channel, and sets the communication channel as the receiver channel.

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 microphone includes a base seat, a tube unit connected the base seat, a sound head, and a cable. The base seat includes a surrounding wall that is formed with at least one through hole, and a base wall that cooperates with the surrounding wall to define a receiving space therebetween, and that has a conical surface for reflecting sound waves toward the through hole. The sound head is disposed in the receiving space, and is spaced apart from the base wall of the base seat. The cable is electrically connected to the sound head and extends through the tube unit.

Abstract: A microphone fixing device is adapted for fixing a microphone to a sound-producing object. The microphone includes a head and a cable electrically connected to the head. The microphone fixing device includes a fixing unit, a buffer seat and a supporting seat. The fixing unit is adapted to be mounted to the sound-producing object, and is formed with at least one cable groove that is adapted for retaining a portion of the cable of the microphone. The buffer seat is mounted on the fixing unit, is spaced apart from the at least one cable groove, and includes at least one resilient wall. The supporting seat is removably mounted on the resilient wall of the buffer seat, and is adapted for supporting the head of the microphone thereon.

Abstract: An antenna device includes: an upright antenna rod connected electrically to and extending upward from a connector; an outer casing mounted on the connector for covering the antenna rod; and a conductive member disposed in the outer casing. The conductive member has an intermediate connecting portion connected electrically to a top of the antenna rod, and two spaced apart sensing portions extending respectively and downward from opposite sides of the intermediate connecting portion toward the connector such that the antenna rod is disposed between the sensing portions.
