Voice Coil

A voice coil (consisting of a former, collar, and winding) is the coil of wire attached to the apex of a loudspeaker cone. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it. The term is also used for voice coil linear motors, which produce a larger force and move a longer distance but work on the same principle.

Famous quotes containing the word voice:

    “Bare night is best. Bare earth is best. Bare, bare,
    Except for our own houses, huddled low
    Beneath the arches and their spangled air,
    Beneath the rhapsodies of fire and fire,
    Where the voice that is in us makes a true response....”
    —Wallace Stevens (1879–1955)
