    摘要: A second piezoelectric vibrator (30) is located in a hollow portion (21) of the first piezoelectric vibrator (20) when seen in a plan view. A support (40) is a frame-shaped member, and the inside surface thereof supports the edge of a vibration member (10). The fundamental resonance frequency of the first piezoelectric vibrator (20) is lower than the fundamental resonance frequency of the second piezoelectric vibrator (30). In addition, the second piezoelectric vibrator (30) overlaps a loop of vibration generated in the vibration member (10) when the first piezoelectric vibrator (20) is driven at the fundamental resonance frequency. Preferably, the center of the second piezoelectric vibrator (30) overlaps the center of a loop of vibration generated in the vibration member (10) by the first piezoelectric vibrator (20).

    摘要: 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.
