Abstract

There is provided a haptic feedback device and an electronic device having the same. The haptic feedback device includes a display panel receiving contact pressure applied thereto; an actuator generating vibrations so as to give different types of haptic feedback according to a change in the contact pressure applied to the display panel; a support plate supporting the actuator; a bonding portion provided between an end portion of the actuator in a lengthwise direction thereof and the support plate so as to fix the actuator to the support plate; and a vibration space expanding portion formed to be recessed in a portion of the support plate corresponding to the actuator.

Claims

1. A haptic feedback device comprising:

a display panel receiving contact pressure applied thereto;

an actuator generating vibrations so as to give different types of haptic feedback according to a change in the contact pressure applied to the display panel;

a support plate supporting the actuator;

a bonding portion provided between an end portion of the actuator in a lengthwise direction thereof and the support plate so as to fix the actuator to the support plate; and

a vibration space expanding portion formed to be recessed in a portion of the support plate corresponding to the actuator.

2. The haptic feedback device of claim 1, wherein the vibration space expanding portion has a depth equal to half of an amplitude of the actuator.

3. The haptic feedback device of claim 1, wherein the vibration space expanding portion has a uniform depth.

4. The haptic feedback device of claim 1, wherein the vibration space expanding portion has an inclined bottom surface.

5. The haptic feedback device of claim 1, wherein the actuator is a piezo actuator or a polymer actuator.

6. An electronic device comprising:

a case having an internal space formed therein; and

a haptic feedback device accommodated to be disposed within the case, the haptic feedback device comprising;

a display panel receiving contact pressure applied thereto;

an actuator generating vibrations so as to give different types of haptic feedback according to a change in the contact pressure applied to the display panel;

a support plate supporting the actuator;

a bonding portion provided between an end portion of the actuator in a lengthwise direction thereof and the support plate so as to fix the actuator to the support plate; and

a vibration space expanding portion formed to be recessed in a portion of the support plate corresponding to the actuator.

7. The electronic device of claim 6, wherein the vibration space expanding portion has a depth equal to half of an amplitude of the actuator.

8. The electronic device of claim 6, wherein the vibration space expanding portion has a uniform depth.

9. The electronic device of claim 6, wherein the vibration space expanding portion has an inclined bottom surface.

10. The electronic device of claim 6, wherein the actuator is a piezo actuator or a polymer actuator.
