  • Patent number: 10397685
    Abstract: An earphone (1) is provided that includes a first vibration plate (31) for vibration by a first piezoelectric element (32) and a cylindrically-shaped casing (2) for transmission of the vibration of the first vibration plate (31) to ear canal cartilage. The first vibration plate (31) is disposed inside the casing (2). The earphone (1) has a structure whereby an amount of sound leakage, which is due to transmission of the vibration of the first vibration plate (31) to the air, is low. The ear canal cartilage transmits sound to the eardrum of only one ear, thereby enabling localization of sound. The woofer (3) maintains sound pressure at low frequencies.

  • Patent number: 8901788
    Abstract: Provided is an electric motor driven by an inverter of PWM method, and devised to retard electrolytic corrosion in a bearing. A rotating body of a rotor comprises an outer iron core configuring an outer peripheral portion of the rotating body, an inner iron core configuring an inner peripheral portion connected to a shaft, a dielectric layer disposed between the outer iron core and the inner iron core, a plurality of insertion holes penetrating the outer iron core in the axial direction, and permanent magnets inserted individually in the plurality of insertion holes. It thus becomes possible to increase impedance of the rotor side (inner ring side of bearing) to approximate it to impedance of the stator side (outer ring side of the bearing) to thereby bring high frequency potentials balanced between the inner ring side and the outer ring side of the bearing, so as to provide the electric motor that retards electrolytic corrosion liable to occur in the bearing, and an electric device equipped with the same.
