FIELD: physics.
SUBSTANCE: invention relates to electrodynamic loudspeakers, namely, to means for reduction of heating of voice coil of loudspeaker. Motor of electrodynamic loudspeaker, including at least one permanent magnet and at least one magnetic field concentrator, for concentration of magnetic field created by permanent magnet, in a magnetic gap, and a voice coil consisting of a frame and winding, located in a magnetic gap, wherein the voice coil has at least one protruding element for heat removal, located on the inner and/or outer surface of the voice coil.
EFFECT: technical result is increase in speaker maximum long-term power.
