    摘要: [Problems]
    To accurately tune the vibration frequency of a suspension during assembly.
    [Means for solving problems]
    Secured positions 3e where a magnetic circuit part 2 is secured to a suspension 3 are provided near to each other. From among the secured positions 3e, secured positions 3e suitable for the characteristics of a suspension 3 to be mounted and the weight of a magnetic circuit part 2 are selected and secured to each other. Thus, the distance between the securing position and the central position of vibration of a suspension 3 and a housing 1 can be changed to tune the frequency to the desired value.

    摘要: In an electroacoustic transducer of the present invention, a casing supports a diaphragm, a drive coil is provided on the diaphragm, a first magnetic structure has a first space in a center thereof provided within the casing such that a center axis penetrates the first space, and a second magnetic structure has a second space in a center thereof provided within the casing on a side opposed to the first magnetic structure with respect to the diaphragm, such that the center axis penetrates the second space. The first magnetic structure is oriented such that a magnetization direction thereof is parallel to the center axis. The second magnetic structure is oriented such that a magnetization direction thereof is opposite to the magnetization direction of the first magnetic structure.

    摘要: Disclosed is a speaker with a built-in direct current motor for selectively generating sound and vibration, which includes: a speaker part, a direct current motor part, and a frame (160). The speaker part has a yoke (150) having a hole formed at the center thereof, a first ring-shaped magnet (140) mounted on the top surface of the peripheral portion of the yoke, a ring-shaped upper plate (130) mounted on the top surface of the first magnet, a vibration plate (110) fixedly mounted to the top surface of the upper plate at the circumferential end thereof, and a generally cylindrical voice coil (120) attached to the bottom surface of the vibration plate. The direct current motor part has a lower plate (240) coupled to the bottom surface of the peripheral portion of the yoke, a flexible printed circuit board disposed on the lower plate, a second ring-shaped magnet (230) mounted on the top surface of the lower plate, a rotary shaft (210) positioned one end thereof on the hole of the yoke and positioned the other end thereof on the hole of the center of the flexible printed circuit board, and an eccentric rotor (220) rotatably mounted on the rotary shaft. According to the present invention, sound or/and vibration is/are selectively outputted from portable equipment such as a cellular phone requiring a vibration function.

    摘要: Pour réduire les effets de champs électromagnétiques perturbateurs intenses sur un haut-parleur (3) d'un téléphone mobile (1), on munit le haut-parleur de deux bobines (18, 20) : une première bobine haute impédance sert à exciter le haut-parleur pour une écoute discrète, une deuxième bobine basse impédance sert à exciter le haut-parleur pour une écoute mains libres. On montre qu'on réduit des effets néfastes de but sans consommer excessivement d'énergie électrique.
