Title:
ACOUSTIC GENERATOR, ACOUSTIC GENERATION DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/024756
Kind Code:
A1
Abstract:
Provided are: an acoustic generator that can generate high-quality acoustics having low frequency-dependent variability in sound pressure; and an acoustic generation device and electronic apparatus that use the acoustic generator. The acoustic generator is provided with a frame, an oscillation body provided to the inside of the frame, and a piezoelectric oscillating element provided on the oscillation body. The oscillation body has a composite structure resulting from the lamination of a first portion on a thin plate and a second portion on the thin plate each having a different elastic modulus.
