Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/153828
Kind Code:
A1
Abstract:
The present invention reduces the amount 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). The electronic device (1) uses the diaphragm (10) to transmit vibration sounds by vibrating part of a human body. The piezoelectric element (30) is vibrated using a processed sound signal comprising a playback sound signal with at least some of frequency components exceeding a prescribed threshold either removed or attenuated.
