ABSTRACT:
An improvement is provided in a loudspeaker having a current carrying coil disposed in the flux gap of a permanent magnet and carrying current to drive the coil and an associated sound diaphragm. The coil is substantially longer than the thickness of the flux gap and has an exposed conductive surface. Contacts are mounted near each side of the flux gap and slidably engage the coil surface to supply current to a limited portion of the coil situated in the flux gap, irrespective of movement of the coil.
