    摘要： A speaker includes a diaphragm, a frame accommodating the diaphragm and an edge attached to an outer periphery of the diaphragm as well as to an inner periphery of the frame so as to retain the diaphragm within an interior of the frame. The edge has a thickness which is smallest at substantially a central portion between the diaphragm and the frame and the vicinity thereof, and increases toward the diaphragm and the frame.

    摘要： A piezoelectric loudspeaker includes: a piezoelectric vibrator including a diaphragm and a piezoelectric member provided on at least one face of the diaphragm, the diaphragm being vibrated by the piezoelectric member; a frame for supporting the piezoelectric vibrator; and a visco-elastic member provided on at least one face of the piezoelectric vibrator. The visco-elastic member is disposed in a substantial center of the piezoelectric vibrator. The visco-elastic member has a bottom face area which accounts for about 11% to about 80% of a bottom face area of the diaphragm.

    摘要： A loudspeaker includes a diaphragm, an edge, and a voice coil. The diaphragm includes a groove having a concave cross section. Also, the diaphragm is in a horizontally or vertically elongated shape. The edge is coupled to an outer circumference of the diaphragm, and has a roughly half-round shaped cross section. The voice coil is bonded to the groove. The voice coil is thicker than a depth of the groove. Also, the voice coil has a cross section in which a dimension in a direction along a plane of the diaphragm is longer than a dimension in a direction perpendicular to the plane of the diaphragm.

    摘要： The loudspeaker includes: a frame; a magnetic circuit portion; a diaphragm transmitting air vibration; a cylindrical voice coil bobbin connected to the diaphragm; a voice coil fixed to an outer peripheral portion of the voice coil bobbin; and a damper holding the voice coil in such a manner that the voice coil is capable of vibrating in a magnetic gap formed between an annular top plate and a center pole included in the magnetic circuit portion. The damper includes a flat portion which has a hole for passing the voice coil bobbin therethrough at its center, and a plurality of roll structures connected to a periphery of the flat portion and having a cross-section including a bent periphery. Each of the plurality of roll structures is fixed to the frame, and the hole of the flat portion is fixed to an outer peripheral surface of the voice coil bobbin.
