Abstract:
Disclosed herein is a linear vibration motor. The motor includes a stator and a vibrator. The stator includes a magnet. The vibrator includes a coil facing the magnet. A weight is coupled to the coil. A PCB is connected to the coil and the stator. An elastic member is coupled to stator and the coil. A damper is provided on the weight at a position facing the elastic member. The damper may be provided between the elastic member and the weight or between the elastic member and the inner surface of a casing. The damper can mitigate metallic high frequency noise attributable to friction between the elastic member and the weight or between the elastic member and the casing. Furthermore, the spatial utilization is increased, thereby enhancing the degree of freedom in designing the linear vibration motor.
