摘要： Disclosed herein is a vibration generator which is used to embody vibration for signal reception indication or a haptic function of wireless communication devices such as mobile phones. The vibration generator includes a casing which has a space therein, a stator which is provided in the casing and is provided with a coil along which current flows, a vibrator which is provided in the casing and is horizontally moved by electromagnetic force, an elastic body which is fixed at a first end thereof to the casing and fixed at a second end thereof to the vibrator, and a residual vibration reducer which is provided between the vibrator and the casing to absorb vibration of the vibrator. Therefore, after the vibration of the vibrator is stopped, the time it takes to stop movement of the vibrator can be markedly reduced.
