Abstract
An outer end portion A of an edge , which is formed at an interior of an outer periphery thereof, is mounted on an attaching surface which is formed inside an outer peripheral rim of a speaker frame . An outer peripheral surface of the outer end portion A is allowed to abut on the outer peripheral rim of the speaker frame . Also, an attaching screw section of the speaker frame is provided on the attaching surface . The outer end portion A has a wall thickness thicker than the thickness of a screw head of the attaching screw section, and is provided with a notch to avoid the attaching screw section . Therefore, the inside area of the speaker frame can be effectively utilized to obtain enough level of outputted sound pressure. Further, since a gasket is unnecessary for positioning and attaching the edge, the number of parts can be reduced to lead cost-down.
