Abstract
A linear vibrator includes a stator having a housing including a receiving space, a moveable unit received in the receiving space, a coil attached to one of the stator and the moveable unit, a magnet assembly attached to the other of the stator and the moveable unit, an elastic member having one end connecting to the moveable unit and another end connecting to the stator for suspending the moveable unit in the receiving space, and a damping block located between the moveable unit and the elastic member, and deformable by the elastic member during the vibration of the moveable unit within a predetermined vibration amplitude. A boost force is produced by the damping block for accelerating the moveable unit to return to balanced position.
