Patent ID: 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.
