Abstract: 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.

Abstract: Voice coil body of a loudspeaker is provided at the outer circumferential wall surface with a supporting section. Diameter of the inner circumference of suspension holder is greater than outer diameter of the voice coil body while diameter of the inner circumference of diaphragm is greater than diameter of the inner circumference of suspension holder for facilitating a gluing of the inner circumferential end of suspension holder and the inner circumferential end of diaphragm on the supporting section and to the voice coil body. By so doing, harmonic distortion of a loudspeaker can be further reduced.

Abstract: A high efficiency loudspeaker without a damper is provided. The loudspeaker includes magnetic circuit having a magnetic gap and a voice coil member, which has movable coil, disposed in the magnetic gap of the magnetic circuit. The loudspeaker also includes a diaphragm, whose inner peripheral part is linked with the voice coil member, outside the magnetic gap and a frame linked with an outer peripheral part of the diaphragm via a first edge. An inner peripheral part of a suspension holder is linked with the voice coil member at a linked position which is closer to the magnetic circuit than a linked position of the diaphragm and the voice coil member. An outer peripheral part of the suspension holder is linked with a frame via a second edge. The first edge and the second edge are substantially symmetrical with each other about a median of a first edge and a second edge.
