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 acurrent 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.
Claims20
A tactile feedback mechanism, comprising:
- a fixed portion;
- a first movable portion, moving relative to the fixed portion;
- a first driving assembly, driving the first movable portion to move along a first direction relative to the fixed portion;
- a second movable portion, moving relative to the fixed portion and the first movable portion;
- and
- a second driving assembly, driving the second movable portion to move along a second direction relative to the fixed portion;
- wherein the first direction and the second direction are different;
- wherein the first movable portion and the second movable portion do not interfere with their respective movements.
