| description | To provide a piezoelectric device which enables further reduction of sound reverberation of ultrasonic components.SOLUTION: A piezoelectric device 1 includes a case 10, a piezoelectric element 20, and a cushioning material 60. The case 10 defines a storage space. The piezoelectric element 20 is disposed in the storage space. The cushioning material 60 includes an air bubble structure 61. The cushioning material 60 is disposed on the piezoelectric element 20 while compressed to the piezoelectric element 20.SELECTED DRAWING: Figure 4
【課題】超音波成分の残響をより一層低減する圧電デバイスを提供すること。【解決手段】圧電デバイス１は、ケース１０と、圧電素子２０と、緩衝材６０と、を備えている。ケース１０は、収容空間を画成している。圧電素子２０は、収容空間内に配置されている。緩衝材６０は、気泡構造体６１を含んでいる。緩衝材６０は、圧電素子２０に向けて圧縮された状態で、圧電素子２０上に配置されている。【選択図】図４ |
