Abstract
A haptic feedback device for a portable terminal. The haptic feedback device includes an input member, a vibration member that passes through the input member, and serves as a rotation axis of the input member, and a piezo actuator in contact with the vibration member. As the input member rotates or pivots with respect to the rotation axis, the piezo actuator actuates to vibrate the vibration member.
Claims9
A haptic feedback device for a portable terminal, the haptic feedback device comprising:
- an input member;
- a vibration member that passes through the input member, and serves as a rotation axis of the input member;
- and
- a piezo actuator in contact with the vibration member,
- wherein as the input member rotates or pivots with respect to the rotation axis, the piezo actuator actuates to vibrate the vibration member, and
- wherein the vibration member vibrates in a straight-line reciprocating movement along the rotation axis.

A haptic feedback device for a portable terminal, the haptic feedback device comprising:
- an input member;
- a vibration member that passes through the input member, and serves as a rotation axis of the input member;
- a stopper located at an end of the vibration member;
- and
- a piezo actuator in contact with the vibration member at an opposite end of the vibration member;
- wherein, as the input member rotates or pivots with respect to the rotation axis, the piezo actuator actuates to vibrate the vibration member, and the input member is guided by the vibration member to perform straight-line movement between the piezo actuator and the stopper.
