Abstract
A linear vibration motor according to an aspect of the invention may include: a case having a cavity to receive a mass therein; a movable part generating a magnetic field inside the case and moving in a transverse direction while being secured to the mass; a coil part generating a force, by which the mass performs a linear reciprocating motion, by interaction with the magnetic field generated from the movable part upon receiving power; and a support plate dividing the cavity in which the coil part is mounted to face the movable part.
