  • Patent number: 11025149
    Abstract: A linear vibration motor comprising a movable element, having an integrated magnet, and a coil wherein winding parts and are caused to cross lines of magnetic force M1 and M2 of the magnet, where the coil is near to the movable element, and wherein the movable element is caused to vibrate along an axial direction through application of power to the coil, wherein: in the magnet, the direction of magnetization is aligned with the axial direction, and the magnet has two magnet pieces and, lined up in a direction that crosses the axial direction, and that have magnetic poles in mutually opposing directions; and other magnet pieces and, having magnetic poles that are magnetized in a crossing direction, where magnetic poles are in contact with, or near to, the identical magnetic poles of the two opposing magnetic poles on the same end sides of the two magnet pieces.

  • Patent number: 10406559
    Abstract: A vibration actuator having a stationary element; a movable element that is supported elastically so as to enable vibration on the stationary element; and a driving source for causing reciprocating vibration of the movable element in relation to the stationary element, wherein: the movable element comprises an opposed face that opposes an opposing face of the stationary element; a magnetic fluid that has viscosity is filled into a gap between the opposing face and the opposed face and is attracted magnetically to at least either the opposing face or the opposed face; and on the other of the opposing face or the opposed face, a holding region for retaining the magnetic fluid is provided, and a lipophobic surface, for repelling the magnetic fluid is provided so as to surround the holding region.
