Title:
ACOUSTIC GENERATOR, ACOUSTIC GENERATION DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2014072711
Kind Code:
A
Abstract:

To provide an acoustic generator in which sound quality can be improved by preventing frequency variations of sound pressure as much as possible by reducing a difference between a resonance peak and a dip in frequency characteristics of sound pressure, an acoustic generation device and an electronic apparatus.

The acoustic generator comprises a vibrator in the shape of a thin plate and an exciter provided on the vibrator. The vibrator includes, on the surface where the exciter is provided, a first region and a second region in which an interval of nodes of standing waves of vibration is different from an interval of nodes of standing waves of vibration in the first region.
