1. An electronic device comprising:
- a piezoelectric element;
a panel supporting the piezoelectric element;
a display unit attached by the panel;
a housing holding the panel, wherein the electronic device generates vibration sound that is transmitted by vibrating a part of a human body in contact with the panel and air-conducted sound by bending the panel directly by the piezoelectric element; and
a buffer material between an inner surface of the display unit that is opposite to a surface of the display unit that the panel is attached and an inner surface of the housing that is opposite to a side of the panel facing the display unit,wherein the piezoelectric element is elongated in shape and has a length longer than a width thereof, and the buffer material is disposed outwards of outermost edges of the piezoelectric element in a longitudinal direction along a length direction of the piezoelectric element.

Abstract
The electronic device can effectively suppress a reduction in sound pressure and an increase in the distortion factor. The electronic device (1) includes a piezoelectric element (30), a panel (10) supporting the piezoelectric element (30), and a housing (60) holding the panel (10). The electronic device (1) causes the panel (10) to generate air-conducted sound and vibration sound that is transmitted by vibrating a part of a human body. A buffer material (90) is disposed between the panel (10) and the housing (60).
