Claims

[Scope of Claim for Utility Model Registration] In a moving coil speaker in which a voice coil is arranged in the gap of an external magnetic circuit made of an electrically insulating magnet, a coil bobbin part and a coil bobbin part extending in the inner circumferential direction from the upper end of the coil bobbin part. The adhesion margin part and the suspension part extending in the outer circumferential direction from the lower edge of the coil bobbin part are integrally molded, and a voice coil is formed in the coil bobbin part, and the suspension is arranged so that the voice coil is located at the center of the gap. 1. A structure of a speaker, characterized in that a diaphragm with a suspension is supported on a part inside a magnetic circuit, and a diaphragm with a suspension is attached to an adhesive part outside the magnetic circuit.
