Abstract
A haptic feedback actuator includes: a vibration plate provided on one surface of a haptic device and transferring vibration; and an actuator provided such that the vibration plate is interposed between the actuator and the haptic device and excited according to a change in the contact pressure of the haptic device to generate vibration.
Claims18
A haptic feedback actuator comprising:
- a vibration plate provided on one surface of a haptic device and transferring vibrations;
- and
- an actuator provided such that the vibration plate is interposed between the actuator and the haptic device and excited according to a change in the contact pressure with the haptic device to generate vibrations.
The actuator of claim 6, wherein the actuator is a piezo-actuator or a polymer actuator.
A haptic feedback device comprising:
- a display panel provided as a haptic device requiring vibrations;
- an actuator excited according to a change in contact pressure with the display panel to generate vibrations;
- and
- a vibration plate disposed between the display panel and the actuator and amplifying vibrations generated from the actuator to transfer the amplified vibrations to the display panel.
