Abstract:
Disclosed herein is a linear vibration motor including: a stator part including a magnet; a vibrator part including a coil facing the magnet to generate electromagnetic force and a printed circuit board having one end coupled to the stator part and the other end coupled to the coil; and an elastic member connecting the stator part and the vibrator part to each other, wherein the stator part further includes a damper facing the vibrator part. The damper is made of a rubber material having lower density in order to alleviate and absorb impact at the time of contact with the vibrator part, thereby making is possible to prevent vibration noise due to residual vibration generated at the time of contact between the vibrator part and the stator part.
