Abstract: The present disclosure provides a vibration device, including a stator, an eccentric wheel and an electromagnetic driving assembly. The eccentric wheel rotates around a rotating shaft relative to the stator. The electromagnetic driving assembly includes at least one magnetic element and an induction coil. The at least one magnetic element is disposed on the eccentric wheel. The induction coil corresponds to the magnetic element, and the induction coil is disposed on the stator. When a current is applied to the induction coil, the induction coil acts with the magnetic element to generate an electromagnetic force to drive the eccentric wheel to rotate around the rotating shaft, so that the vibration device generates a vibration. The rotating shaft is disposed on the stator.
