Abstract

To reduce attenuation of vibration in provision of a tactile sensation when both of a piezoelectric element for providing a tactile sensation and a piezoelectric element for transmitting sound are provided to a panel, an electronic device 1 includes a panel 10 , a first piezoelectric element 31 and a second piezoelectric element 32 that are attached to the panel 10 , and a control unit 50 for controlling such that the second piezoelectric element 32 is driven to output sound and, when the panel 10 detects a contact, such that the first piezoelectric element 31 is driven, and that the control unit 50 , when the panel 10 detects the contact, controls such that the second piezoelectric element 32 is driven as well as the first piezoelectric element 31.

First claim

What is claimed is:

1. An electronic device comprising:
a panel;
a housing;
a first piezoelectric element and a second piezoelectric element that are attached to the panel; and
a control unit configured to control such that the second piezoelectric element is driven to output sound and, when the panel detects a contact, to control such that the first piezoelectric element is driven, as well as the second piezoelectric element, wherein
the second piezoelectric element is attached to the panel in a position near a portion of the panel where the panel is attached to the housing, and the first piezoelectric element is attached to the panel in another position farther than the position from the portion.

2. An electronic device comprising:
a panel;
a housing;
a first piezoelectric element attached to the panel for detecting a pressure on the panel;
a second piezoelectric element attached to the panel; and
a control unit configured to control such that the second piezoelectric element is driven to output sound and, when data based on the pressure detected by the first piezoelectric element satisfies a predetermined standard while the panel is detecting a contact, to control such that the first piezoelectric element is driven as well as the second piezoelectric element, wherein
the second piezoelectric element is attached to the panel in a position near a portion of the panel where the panel is attached to the housing, and the first piezoelectric element is attached to the panel in another position farther than the position from the portion.

3. An electronic device comprising:
a panel;
a housing;
a first piezoelectric element for providing a tactile sensation;
a second piezoelectric element for transmitting sound; and
a control unit, wherein
the first piezoelectric element and the second piezoelectric element are attached to the panel,
the control unit, when the panel detects a contact, controls such that the second piezoelectric element is driven as well as the first piezoelectric element, and
the second piezoelectric element is attached to the panel in a position near a portion of the panel where the panel is attached to the housing, and the first piezoelectric element is attached to the panel in another position farther than the position from the portion.

4. The electronic device according to claim 3 , comprising:
a pressure detection unit configured to detect a pressure on a panel, wherein
the control unit, when data based on the pressure detected by the pressure detection unit satisfies a predetermined standard while the panel is detecting the contact, controls such that the second piezoelectric element is driven as well as the first piezoelectric element.
