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:

    O make harmonious mix of voice and string
    To him by whom the skies with clouds are lin’d;
    By whom the rain, from clouds to drop assign’d,
    Supples the clods of summer-scorched fields,
    —Bible: Hebrew Psalm CXLVII (Paraphrased by The Countess of Pembroke)
