Title:
ACOUSTIC GENERATOR, ACOUSTIC GENERATION DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/050214
Kind Code:
A1
Abstract:
The present invention addresses the problem of flattening frequency characteristics. In order to solve the problem, an acoustic generator according to an embodiment is equipped with a piezoelectric component (exciter) (1) and a film (membranous vibrating body) (3). The piezoelectric component (1) vibrates when an electric signal is input thereto. The film (3), to which the piezoelectric component (1) is joined via a joint material (21), vibrates together with the piezoelectric component (1) as the piezoelectric component (1) vibrates. In addition, the acoustic generator according to the embodiment has voids (21a) inside the joint material (21).
