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:

    It is singular to look round upon a country where the dreams of sages, smiled at as utopian, seem distinctly realized, a people voluntarily submitting to laws of their own imposing, with arms in their hands respecting the voice of a government which their breath created and which their breath could in a moment destroy!
    Frances Wright (1795–1852)
