Entries found for search: voice coil

voice coil : The transducer part of a loudspeaker, consisting of a coil of wire mounted on a frame. Variations in the electrical signal passing through the coil cause it to be repulsed from, or attracted to, a fixed magnet in proportion to the frequency and amplitude of the signal. The resulting motion is mechanically transmitted to an attached cone, whose piston effect excites the surrounding air to reproduce recorded sound.
