PURPOSE: A linear vibration motor is provided to easily correct frequencies by multi points laser welding a case and an elastic member. CONSTITUTION: A case(110) protects an embedded part from outside. An elastic member(120) is fixed at the upper corner part of the inner part of the case and supports vertical vibration of the vibrator. The elastic member is fixed by laser welding(A) performed from the outside of the case. A bracket(130) is fixed at the lower part of the case. A circuit board(140) is mounted on the upper part of the bracket.
