Abstract
In order to suppress reduction in vibration due to interference by use of a simple structure, a display input device (6) includes: a display portion (62); a touch panel (63) that is provided on an upper surface of the display portion (62) and detects a position of a touch operation; a plurality of piezoelectric elements (651 to 656) provided in a divided manner on a front surface and a back surface of the touch panel (63); and a drive portion (64) that drives the piezoelectric elements (651 to 656) in accordance with a touch operation on the touch panel (63), thereby to vibrate the touch panel (63).
Claims7
A display input device comprising:
- a display portion;
- a touch panel provided on an upper surface of the display portion and configured to detect a position of a touch operation;
- a plurality of piezoelectric elements provided in a divided manner on a front surface and a back surface of the touch panel;
- and
- a drive portion configured to drive the piezoelectric elements in accordance with a touch operation on the touch panel, thereby to vibrate the touch panel.
A touch panel device comprising:
- a display portion configured to display a screen;
- a plurality of elastic members provided on an upper surface of the display portion;
- a touch panel fixed to upper surfaces of the plurality of elastic members;
- and
- a plurality of piezoelectric elements configured to vibrate the touch panel, wherein
- the upper surfaces of the plurality of elastic members are set to have heights at two or more levels, and the touch panel is fixed in a curved state.
