Abstract
A first diaphragm resonantly vibrates in a phase opposite to a phase of a unimorph piezoelectric vibrator in a direction orthogonal to the first diaphragm. A dimension in a longitudinal direction inside at least one frame body is four or more times a dimension in a lateral direction orthogonal to the longitudinal direction inside the at least one frame body. A second diaphragm is located in a region between both edges in the lateral direction of an inner peripheral surface of the at least one frame body as viewed in the direction orthogonal to the first diaphragm, and average distances in the lateral direction between edges in the lateral direction of the inner peripheral surface of the at least one frame body and edges in the lateral direction of the second diaphragm are one sixth or less the dimension in the lateral direction inside the at least one frame body.
