  • Publication number: 20190364366
    Abstract: In an electroacoustic converter, a dome-shaped diaphragm having anisotropy in rigidity is formed by shaping fiber reinforced plastic having anisotropy in fiber orientation. A voice coil bobbin, in a hollow cylindrical shape, on which a voice coil is wound is linked to the outer edge of the diaphragm so that the shape of the linked portion becomes circular when viewed in the axial direction of the diaphragm. The diaphragm vibrates due to an electromagnetic action by a magnetic flux that is generated in a magnetic circuit and flows in the voice coil and the current of an audio signal flowing in the voice coil.

  • Patent number: 10462555
    Abstract: An opening portion is formed along an outer peripheral edge of a diaphragm in a second casing portion partitioned by the diaphragm. In the opening portion, a plurality of fins is arranged at regular intervals, and an air passage is formed between every adjacent two of the fins. The fin and the air passage are formed so as to be at an angle to a corresponding imaginary line that extends from the vibration center line of the diaphragm in the radial direction. By forming each of the air passages obliquely, noise generated by an air flow due to sound pressure is reduced.

  • Patent number: 9908216
    Abstract: A method of manufacturing a grinding wheel, and a grinding wheel. After a first overcoat layer is formed on each of CBN abrasive grains, a second overcoat layer that is plastically deformed under a pressure lower than a pressure under which the first overcoat layer is deformed, is formed on the outer side of the first overcoat layer to manufacture coated abrasive grains. The coated abrasive grains are subjected to pressure-molding to be formed into a prescribed shape under a pressure that is equal to or higher than a pressure under which the second overcoat layer is plastically deformed. The second overcoat layers are deformed and flow to form a molded material having a structure in which the first overcoat layers contact each other, and the flowing second overcoat layers are moved into clearances between the coated abrasive grains.
