Document Type and Number:
Japanese Patent JP4892612
Kind Code:
B2
Abstract:
A speaker device where the dip in the middle sound range is reduced, which provides reproduced sound of comparatively high quality, and provides reproduced sound of comparatively high sound pressure. In the speaker device, a support member for a speaker vibrator is adopted for an edge. The speaker device has a movable part (85) having bent parts, or more specifically, having a top bent part, an inner bent part, and an outer bent part. Because the movable part (85) is formed such that the top bent part is positioned closer to the radial center of the speaker device than the radial center between the inner bent part and the outer bent part, the edge (8) has comparatively high rigidity. Consequently, the dip in the middle sound range can be reduced by a simple structure without forming, for example, a damping agent layer and a resin layer on the support member for a speaker vibrator.
