Реферат: Loudspeaker components, and loudspeakers made with such components, are embedded with directionally thermally conductive fibers, such as pitch-based carbon fibers. The fibers are arranged so that they conduct heat away from the voice coil to the speaker frame or a dedicated heat sink. The components that can have thermally conductive fibers embedded in them include the former tube, the voice cone, and the spider.
