Microphones Microphones are available at Kynix Electronics. Kynix offers inventory, pricing, & datasheets for Microphones. Microphones are used in many applications such as telephones, hearing aids, public address systems for public events, motion picture production, and live, two-way radios, megaphones, radio and television broadcasting, and in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic checking or knock sensors. Microphones are transducers which detect sound signals and produce an electrical image of the sound, i.e., they produce a voltage or a current which is proportional to the sound signal. The most common microphones for musical use are dynamic, ribbon, or condenser microphones. Besides the variety of basic mechanisms, microphones can be designed with different directional patterns and different impedances. To know more, please view our large section of Microphones below.
