Abstract

A mobile electronic device includes: a housing that includes an opening part; a display part that includes a display area and that is disposed inside the housing, wherein the display area is visible from the outer section of the housing through the opening part; a touch panel that is stacked and disposed on the outer side of the housing facing the display area of the display part, and that is exposed to the outer section of the housing; and a vibration part that is disposed in the touch panel in the area that is on the outer circumferential side of the display part in the planar direction of the touch panel.

Claims

1. A mobile electronic device, comprising:

a housing that comprises an opening part;

a display part that comprises a display area and that is disposed inside the housing, wherein the display area is visible from the outer section of the housing through the opening part;

a touch panel that is stacked and disposed on the outer side of the housing facing the display area of the display part, and that is exposed to the outer section of the housing;

a vibration part that vibrates, the vibration part disposed in the touch panel in the area that is on the outer circumferential side of the display part in the planar direction of the touch panel;

a first elastic member that is disposed between the touch panel and the housing, wherein the first elastic member is disposed at a position overlapping the surrounding section of the opening part for the housing in the stacking direction of the display part and the touch panel; and

a second elastic member that is disposed between the display part and the touch panel;

wherein the display part comprises a non-display area that is adjacent to the display area, the non-display area overlaps with the surrounding section of the opening part of the housing in the stacking direction, and the second elastic member is disposed between the non-display area and the touch panel.

2. The mobile electronic device according to claim 1, wherein the vibration part, in the stacking direction of the display part and the touch panel, are disposed on the surface of the inner side of the housing of the touch panel.

3. The mobile electronic device according to claim 2, wherein the display part and the vibration part are disposed in the planar direction and side by side to each other in the inner section of the housing.

4. The mobile electronic device according to claim 2, wherein the thickness of the vibration part is thinner than the thickness of the display part in the stacking direction of the display part and the touch panel.

5. The mobile electronic device according to claim 1, wherein the vibration part is disposed at a position overlapping the surrounding section of the opening part in the stacking direction of the display part and the touch panel.

6. The mobile electronic device according to claim 1, wherein the first elastic member is a member having waterproof properties and/or dust resistance.

7. The mobile electronic device according to claim 1, further comprising:

the first elastic member that is disposed between the touch panel and the housing; and

the second elastic member that is disposed between the display part and the touch panel, wherein an elastic modulus of the second elastic member is larger than an elastic modulus of the first elastic member.

8. The mobile electronic device according to claim 7, wherein:

the touch panel is a capacitance type touch panel.

9. The mobile electronic device according to claim 1, wherein:

the touch panel comprises;

an operating area that faces the display area of the display part;

a non-operating area that is adjacent to the operating area;

a supply conducting wire that is disposed in the non-operating area, and that supplies the electric power to the vibration part; and

a ground pattern that divides the operating area and the non-operating area.

10. The mobile electronic device according to claim 9, wherein:

the non-operating area of the touch panel overlaps with the surrounding section of the opening part of the housing in the stacking direction.

11. The mobile electronic device according to claim 1, further comprising

a circuit board that is disposed on the opposite side from the touch panel in the stacking direction with respect to the display part,

wherein the circuit board comprises a supply conducting wire that supplies electric power to the vibration part.

12. The mobile electronic device according to claim 11, further comprising a magnetic sheet that is disposed between the touch panel and the vibration part.

13. The mobile electronic device according to claim 1, wherein:

the touch panel is a capacitance type touch panel.
