Abstract
Heat transfer in the voice coil of a dynamic loudspeaker is analyzed in detail with allowance for its design features. The theoretical estimates of the investigated process are corroborated experimentally; it is shown, in particular, that the nature and intensity of heat transfer in the voice coil depends significantly on its position in the magnetic gap of the dynamic speaker. The most favorable regime in this case is conductive heat transfer, when the coil is situated exactly in the gap. Conclusions are drawn as to possible ways of increasing the rate of heat transfer in the voice coil of a dynamic speaker.
