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:
“When the Church of Jesus
Shuts its outer door,
Lest the roar of traffic
Drown the voice of prayer:
May our prayers, Lord, make us
Ten times more aware
That the world we banish
Is our Christian care.”
—Frederick Pratt Green (b. 1903)
