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 we read a story, we inhabit it. The covers of the book are like a roof and four walls. What is to happen next will take place within the four walls of the story. And this is possible because the story’s voice makes everything its own.”
—John Berger (b. 1926)
