A vibrator designed to be integrated into a portable electronic device as part of a haptic alert device has a linear electric motor that is coupled to actively drive a moveable weight in back-and-forth directions to produce the desired vibration. A lock mechanism has a restraining member that is biased into a lock position, which prevents the moveable weight from moving in the back-and-forth directions when the vibrator is inactive. The lock mechanism may be controlled by a second electric motor.
