PROBLEM TO BE SOLVED: To solve a problem associated with speakers for use in various kinds of acoustic equipment, that needs for the enhancement of resistance to input should be met. SOLUTION: The frame 26 of the speaker is composed of a resin with alumina fine particles mixed therein. The frame 26 is thereby enhanced in thermal conductivity, properties of heat radiation, heat resistance, rigidity, and form stability for the enhancement of the resistance to input of the speaker.
