SPEAKER SYSTEM

摘要

PROBLEM TO BE SOLVED: To enhance a heat radiating effect of a heat generated by a voice coil and to improve resistance to input of the speaker. SOLUTION: A radiation layer 14 is formed to a part of a voice coil 2 whose heat radiation is made conventionally rely upon air convection, heat generated by the voice coil 2 is converted into an infrared ray and then radiated. Thus, the heat transfer speed is increased and the cooling effect of the voice coil 2 is promoted so as to improve resistance to input of the speaker in this speaker system.
