Abstract

An elastic vibration plate (110) is divided into a plurality of elastic vibrating regions (112) through slits (111) having a predetermined shape, a plurality of piezoelectric vibrators (120) which are individually mounted on at least some of the plurality of elastic vibrating regions (112) on the elastic vibration plate (110) undergo elastic vibration due to application of an electric field. Therefore, it is possible to vibrate the plurality of elastic vibrating regions (112) on a single elastic vibration plate (110) using the plurality of piezoelectric vibrators (120). Therefore, it is possible to adjust the peak value and the like of the oscillation frequency at will in each of the plurality of elastic vibrating regions.
