ABSTRACT:
A wind noise and vibration noise reducing microphone arrangement is formed in a bullet-shaped housing (12) having a rounded front portion (13) and a flat rear portion (15). The rear portion is substantially perpendicular to the side portions (14) and contains a transducer (10) facing in the opposite direction from the forward portion. The transducer is mounted to the housing with an elastomeric member (25) that also serves as a seal between the transducer and the housing. The elastomeric member also reduces vibrations transmitted to the microphone. A mounting means (30) is attached to the housing. The mounting means has a vibration isolation member (32) to reduce vibrations transmitted to the housing. The mounting means can be an aerodynamic pedestal attached to the housing, with an elastomeric member attached to the pedestal to reduce vibrations. The pedestal is attached to a vehicle such as a bicycle (6), motorcycle, glider, or boat, and the elastomeric member reduces the vibration transmitted from the vehicle to the housing. The microphone arrangement is connected to a radio transmitter (4) mounted on the bicycle, and transmits the rider's voice to another remote radio receiver.
