    摘要: A circuit board comprising a composite resin and a metal plate, the metal plate forming circuit patterns. The composite resin comprises 70-95 parts by weight of inorganic filler, and 5-30 parts by weight of a resin composition including a thermosetting resin and a hardener. The metal plate is surface treated to reinforce the adhesion at least at one surface contacting with the composite resin. The composite resin fills spaces between the circuit patterns, and the composite resin composition and the metal plate form a plane at a side of the metal plate for mounting components. Since the resin composition including the inorganic filler is also present in the spaces between circuit patterns of a metal plate, heat dissipation characteristic of the circuit board is extremely high, and is suited for electronic apparatus containing heat generating parts such as power circuit.

    摘要: A bond magnet according to the present invention is anisotropic, and a magnetic field is oriented from a lowest edge of side surface of the bond magnet toward an upper section of side surface of the bond magnet. Further, the bond magnet is configured such that the upper section of side surface of the bond magnet is disposed closer to a yoke side surface of a yoke than the lower side surface of the bond magnet is, and the upper section of side surface of the bond magnet faces against the yoke side surface. With this, a magnetic gap is provided between the upper section of side surface of the bond magnet and the yoke side surface. Thus, it is possible to improve a magnetism characteristic of the bond magnet, and to achieve both of magnetic efficiency and productivity of a magnetic circuit for a speaker.

    摘要: The present invention relates to an electromagnetic electro-acoustic transducer to be used for generating an incoming indicator tone for mobile phones and the like. A resin magnet 11 is formed with a hard magnetic material and a soft magnetic material, the lowest resonant frequency can be easily set by changing the magnetic flux density in a magnetic gap by changing the compound ratio of the soft magnetic material, a high magnetic flux density is attained by increasing the magnetic permeability of the resin magnet 11 with the soft magnetic material, thus achieving a smaller size as well as a higher sound pressure through an increase in the driving force exerted to the diaphragm.
