Contemplated planar magnetic induction transducers comprise a driver portion that provides a static magnetic field and a dynamic magnetic field to an electrically conductive sound producing membrane to thereby induce a current in the membrane that operates as a voice coil. Most typically, the dynamic magnetic field is produced by a coil that surrounds the magnet, and the membrane is floating above the driver portion. In especially preferred aspects, the sound producing membrane is physically independent from the driver portion and can be separately installed from the driver portion.
