Abstract: A lead wire of a voice coil is wired along the surface of a diaphragm. The lead wire is bent toward a reverse side of the diaphragm at a peripheral edge portion of the diaphragm. The lead wire is led to the interior of a frame. An external terminal is provided to extend from outside to inside the frame. In addition, a connecting portion for connecting the lead wire and the external terminal is provided inside the frame. The connecting portion is prevented from coming into contact with another part and becoming short-circuited.

Abstract: An external magnetic-type speaker apparatus includes a magnetic circuit that is provided with a yoke having a center pole, ring-shaped magnet and plate. The magnetic circuit and the edge of a vibrating plate are attached to a support frame. Ventilation holes are formed in the side surface of the support frame for allowing air inside the apparatus to escape.

Abstract: There is provided a speaker or a speaker system which has no chance of disabled ventilating air in a space enclosed with a voice coil bobbin to outside of the magnetic circuit through a throughhole C formed in a magnetic circuit to communicate with the space enclosed with a voice coil bobbin, even if mounting a speaker between inner surfaces of a casing, because of enabled ventilating air from a space enclosed with a voice coil bobbin to outside of a magnetic circuit through an air path 3c formed in the magnetic circuit to communicate with the throughhole C.
