Document Type and Number:
Japanese Patent JP5962848
Kind Code:

Abstract:
A piezoelectric blower includes an outer casing and a blower main body. The outer casing houses the blower main body. The blower main body includes a top plate, side plate, first vibrating plate, piezoelectric element, intermediate plate, second vibrating plate, side plate, and bottom plate and has a structure in which they are laminated in sequence. The top plate, side plate, and first vibrating plate define a columnar first blower space. The second vibrating plate, side plate, bottom plate define a columnar second blower space. The distance from a neutral plane of the piezoelectric element in the thickness direction to a surface of the second vibrating plate, the surface being near the piezoelectric element, is longer than the distance from the neutral plane to a surface of the first vibrating plate, the surface being near the piezoelectric element.
