Document Type and Number:
WIPO Patent Application WO/2014/097863
Kind Code:
A1
Abstract:
[Problem] To obtain excellent acoustic pressure frequency characteristics.
[Solution] This acoustic generator is provided with a frame body (10), a diaphragm (20) fixed to the frame body (10), and a piezoelectric vibration element (30) as an exciter, said vibration element being provided on the diaphragm (20). When the frame body (10) is cut by a plane perpendicular to a main surface of the diaphragm (20), the frame body (10) has a portion where the width of the frame body is uneven in the thickness direction.
