Disclosed herein is a linear vibration motor. A stator includes a coil which forms a magnetic field using an external power applied thereto. A vibrator includes a magnet which faces the coil, and a yoke which has a coupling part. The magnet is coupled to the coupling part. An elastic member has a first end coupled to the stator, and a second end coupled to the yoke. The elastic member elastically supports linear vibration motion of the vibrator. The coupling part has a plurality of openings therein so that an electromagnetic force generated by electromagnetic induction of the magnet and the coil leaks out through the openings.
