ABSTRACT:
A double cone-type loudspeaker which comprises a subcone made of highly heat-conductive material, attached to the front of the main cone and to a voice coil bobbin made of highly heat-conductive material. Heat generated in the coil portion of the voice coil travels directly to the bobbin portion and subcone, and is released to the front of the speaker. Consequently, a double cone-type loudspeaker with high maximum input power and high heat radiating capability is achieved.
