Abstract
The coil form for a loudspeaker voice coil is made of a material having high thermal conductivity. The coil form is attached to or integrally formed with a highly thermally conductive spider member which resiliently supports the coil form on the frame structure of the speaker, which also has high thermal conductivity. In one embodiment of the invention a heat sink member to facilitate the dissipation of the thermal energy is attached to the speaker frame structure. In an embodiment involving a horn type speaker, the horn element, which is made of a thermally conductive material, is attached to the speaker frame and also functions as a heat dissipator. In this manner, the likelihood of overheating of the speaker voice coil is greatly diminished.
