A linear vibrator includes a stator having a housing including a receiving space therein, a moveable unit, an elastic member suspending the moveable unit in the receiving space, and a protection member located between the stator and the moveable unit. The protection member forms a first bevel along a vibration direction of the moveable unit, one of the stator and the moveable unit includes a second bevel corresponding to the first bevel. The second bevel keeps a distance from the first bevel for rubbing each other when the linear vibrator falls.
