Abstract
There is provided a haptic feedback device. The haptic feedback device may include a case, a vibration member installed in the case, to vibrate, a vibration element formed in the vibration member, to generate vibrations, and a first impact absorbing member preventing a collision between the vibration member and the case.
Claims14
A haptic feedback device, comprising:
- a case;
- a vibration member disposed in the case and configured to vibrate;
- a vibration element disposed in the vibration member and configured to generate vibrations;
- a mass member attached to the vibration member;
- a first impact absorbing member configured to prevent a collision between the vibration member and the case when the vibration member is excessively vibrated by external force;
- and
- a second impact absorbing member attached to the mass member to prevent a collision between the mass member and the case,
- wherein both ends of the vibration member are directly fixed to the case such that the vibration member transmits the vibrations to the case, and the vibration element is disposed on a first surface of the vibration member, and the mass member is disposed directly on a second surface of the vibration member,
- wherein the first impact absorbing member is respectively disposed in the vibration member and in the case,
- wherein the vibration member includes a first plate member and a second plate member, and
- wherein the second plate member extends from a side surface of the first plate member, and is bent in a direction perpendicular to a plane of the first plate member.
