    摘要： A magnetic circuit for a loudspeaker includes a magnet and a top plate. The magnet is made of a bonded magnet. The magnet and the top plate are configured to satisfy at least one of conditions that an inner diameter of the magnet is identical to an inner diameter of the top plate, and that an outer diameter of the magnet is identical to an outer diameter of the top plate. This configuration eliminates a wasted space inside the magnetic circuit, and protrusion of the magnet to outside, hence providing a light and efficient magnetic circuit.

    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： A loudspeaker comprising at least one magnet 27, a yoke 24 fixed to a bottom surface of the magnet, a flat plate 26 fixed on an upper surface of the magnet, a magnetic circuit 29 having a magnetic gap 28 formed between the plate and the yoke, and a flat diaphragm 23 provided with a coil 21 disposed above the magnetic gap. The magnet has a width greater than that of the plate, and at least a part of the upper surface of the magnet is exposed so that it directly faces the diaphragm. According to the structure of the present invention, a larger volume magnet can be used without increasing the size of the magnetic circuit. Furthermore, as magnetic flux can be concentrated in an upper region of the magnetic gap, the magnetic circuit becomes efficient and compact. Thus a compact and high-efficiency loudspeaker for high frequency sound reproduction can be provided.

    摘要： A loudspeaker includes a magnetic circuit comprising a center plate, first and second magnets disposed respectively on a lower surface and an upper surface of the center plate and magnetized to be repulsive to each other, an under plate disposed at a lower surface of the first magnet, and a yoke. The loudspeaker further comprises a voice coil, a diaphragm, an edge coupled with the outer circumferential edge of the diaphragm, and a frame. The above-described magnetic circuit further comprises a top plate disposed on an upper surface of the second magnet. Both of the second magnet and the top plate have a ring shape, the inner and the outer diameters of the second magnet and the top plate being substantially the same. Outer diameters of the second magnet and the top plate are smaller than that of the center plate, and the center plate is provided on its upper surface with a protrusion for positioning of the second magnet. A compact loudspeaker having a sufficient driving force can be provided in accordance with the present invention.
