<P>PROBLEM TO BE SOLVED: To provide a vibration actuator in which a single magnetic pole is magnetized reliably and easily in the radial direction of a magnet, and down-sizing is promoted easily so as to reduce the diameter of the enclosure. <P>SOLUTION: The cylindrical magnet 4 of a vibration actuator 1 consists of magnet portions 4A, 4B magnetized in the radial direction and divided into multiple portions, and since the adjoining magnet portions 4A, 4B have different poles in the direction of a vibration axis L, the poles do not repel when bonding the magnet portions 4A, 4B, which are thereby bonded easily. When the magnet 4 is configured in this manner, a coil 3 consists of coil parts 3A, 3B divided into a plurality of parts corresponding to the magnet portions 4A, 4B in the direction of the vibration axis L, and the winding direction of the winding of the adjoining coil parts 3A, 3B is reversed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
