Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/153827
Kind Code:
A1
Abstract:
The present invention makes it difficult to discern the content of sound escaping from a diaphragm that is vibrated by a piezoelectric element. This electronic device (1) is provided with a piezoelectric element (30) and a diaphragm (10) that is vibrated by said piezoelectric element (30). Said diaphragm (10) produces air-conducted sounds and vibration sounds. Said vibration sounds are transmitted by way of part of a human body being vibrated. This electronic device (1) is also provided with an air-conducted-sound attenuation part that makes some or all of the air-conducted sounds difficult to hear.
