ABSTRACT:
A loudspeaker with a voice coil reciprocally disposed in a magnetic gap provided with means for conducting heat outwardly from the gap comprising a flat circular web disposal in abuttment with the magnetic structure and extending between a cylindrical collar which confronts the voice coil former to a circular ring integral with the frame of the loudspeaker and including vanes extending from the web between the collar and ring. The voice coil former is limited to axial motion by a pair of spaced flat disks mounted at their centers on the central pole piece normal to the axis of motion and on the coil former at their perimeters.
