    摘要: Loudspeaker (20) has frame (5), magnetic circuit (1), voice coil (2), diaphragm (3), first combination (12a) and second combination (12b). First combination (12a) and second combination (12b) are both provided closer to magnetic circuit (1) than diaphragm (3), the inner rims of which are connected to voice coil (2) while the outer rims are to frame (5). First combination (12a) has first damper (10a) and first edge (11a) wherein first edge (11a) has first edge protrusion (21a) protruding in a direction toward diaphragm (3) or in a direction opposite to diaphragm (3). Second combination (12b) has second damper (10b) and second edge (11b) wherein second edge (11b) has second edge protrusion (21b) protruding in an opposite direction to the protruding direction of first edge protrusion (21a). This structure obtains loudspeaker (20) that distortion is suppressed and weight reduction is easy for an excursion part thus improved in driving efficiency.

    摘要: An uncured fluid adhesive is charged into a groove surrounding the outer circumference of a voice coil so that the inner circumferential edge of a diaphragm is immersed in the adhesive. The cured adhesive securely bonds the diaphragm to the voice coil, and thus the diaphragm can be driven at high output.
