Abstract
Provided is a linear vibration motor having a structure requiring less space and also having good responsiveness. This linear vibration motor is characterized by having a mover having weights affixed on the longitudinal end side of a pair of long magnets; a coil provided in a long shape in the longitudinal direction of the pair of magnets and driving and reciprocating the mover in the transverse direction by a magnetic action produced by the conduction of electricity; a base to which the coil is affixed; and an elastic member elastically deformed by the reciprocation of the mover.
Claims9
A linear vibration motor comprising:
- a movable element securing a weight body to a lengthwise-direction end portion side of a pair of long magnets;
- a coil, provided in a long shape along the lengthwise direction of the pair of magnets, reciprocatingly driving the movable element, in the short direction, through magnetism when power is supplied;
- a substrate whereon the coil is secured;
- and
- an elastic member that undergoes elastic deformation through the reciprocating motion of the movable element.
