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.

Abstract: A speaker has a diaphragm (16) and a suspension holder (19) supporting the diaphragm from the back surface of the diaphragm. The diaphragm has a bent section (21) disposed between its outer periphery and its inner periphery, with the portion to the outer periphery having a conical shape. The diaphragm is coupled to the suspension holder at the bent section. This configuration can omit a damper that causes nonlinearity and asymmetry of suspension, to reduce the harmonic distortion of the speaker and improve the power linearity and the performance of the speaker. The diaphragm can have a flat configuration at its inner peripheral portion, can be secured with sufficient rigidity, and can be rigidly secured to a frame of the sneaker. This can reduce the thickness of the diaphragm and enable formation of a smaller, low profile sneaker can be realized.

Abstract: A speaker includes a frame, a diaphragm fixed through a first edge, a voice coil, a magnetic circuit and a suspension holder fixed through a second edge. The first and the second edges are substantially symmetrical in shape with respect to the space between them and the inner periphery of the suspension holder and the inner periphery of the diaphragm are fixed to a part outside of the magnetic gap of the voice coil. Furthermore, the magnetic circuit has a magnet provided outside of the bottom of the frame with its outer periphery extending at least beyond the center of the second edge. The magnetic gap of the magnetic circuit is pushed into the frame past the bottom of the frame. The speaker provides lower distortion and increased audio output.

Abstract: A loudspeaker has a configuration in which edge diameter in the cross section of second edge coupled to suspension holder is set to be larger than edge diameter in the cross section of first edge coupled to diaphragm. With such a configuration, a loudspeaker with reduced harmonic distortion is provided.
