The Audio Products category encompasses various types of electroacoustic transducers--devices which change sound energy into an electrical signal and vice-versa. They are grouped according to their basic function, such as changing sound into an electrical signal (microphones), an electrical signal into sound (speakers), or an electric power source into some manner of noise (buzzers, sirens). Also included are related accessories for such products, such as gaskets and mounting hardware.
