Document Type and Number:
WIPO Patent Application WO/2013/172018
Kind Code:
A1
Abstract:
Provided is an electronic device by which decline of acoustic pressure and increase of distortion can be effectively minimized. The device is provided with a piezoelectric element (30), a panel (10) supporting the piezoelectric element (30), and a chassis (60) for retaining the panel (10). In this electronic device (1), in which air-conducted sound and vibration sound transmitted by vibration of part of the body are generated by the panel (10), cushioning materials (90) are arranged between the panel (10) and the chassis (60).
