Abstract

An electronic device includes a haptic touch panel including a touch surface, a housing, a counter mass, an actuator and an elastic plate. The actuator is connected to the haptic touch panel. The elastic plate includes a first portion connected to the haptic touch panel, a second portion connected to the counter mass, and a third portion connected to the housing.

Claims

1. An electronic device comprising:

a haptic touch panel including a touch surface;

a housing;

a counter mass;

an actuator connected between the haptic touch panel and the counter mass for moving the haptic touch panel and the counter mass relative to the housing in opposite directions; and

an elastic plate comprising a first portion connected to the haptic touch panel, a second portion connected to the counter mass, and a third portion connected to the housing.

2. The electronic device according to claim 1, wherein the elastic plate further comprises a first elastic member connected between the first portion and the third portion, and a second elastic member connected between the second portion and the third portion.

3. The electronic device according to claim 2, wherein the first portion, the third portion and the first elastic member are disposed in the same plane.

4. The electronic device according to claim 3, wherein the elastic plate has a first separating slot separating the first elastic member from the third portion.

5. The electronic device according to claim 2, wherein the second portion, the third portion and the second elastic member are disposed in the same plane.

6. The electronic device according to claim 5, wherein the elastic plate has a second separating slot separating the second elastic member from the second portion.

7. The electronic device according to claim 2, wherein the first portion and the third portion are disposed in different planes.

8. The electronic device according to claim 7, wherein the first elastic member comprises a first folded portion, a second folded portion and a first connecting portion between the first folded portion and the second folded portion, and the first folded portion and the second folded portion are located on different levels along a direction vertical to the touch surface of the haptic touch panel.

9. The electronic device according to claim 2, wherein the second portion and the third portion are disposed in different planes.

10. The electronic device according to claim 9, wherein the second elastic member comprises a third folded portion, a fourth folded portion and a second connecting portion between the third folded portion and the fourth folded portion, and the third folded portion and the fourth folded portion are located on different levels along a direction vertical to the touch surface of the haptic touch panel.

11. The electronic device according to claim 2, wherein the first elastic member and the second elastic member are formed of leaf springs.

12. The electronic device according to claim 1, wherein movements of the haptic touch panel and the counter mass generated by the actuator are in a direction vertical to the touch surface of the haptic touch panel.

13. The electronic device according to claim 1, wherein movements of the haptic touch panel and the counter mass generated by the actuator are in a direction horizontal to the touch surface of the haptic touch panel.

14. The electronic device according to claim 1, wherein the actuator is a piezoelectric actuator or a magnetic actuator.
