| Zusammenfassung: | A piezoelectric vibration device, including a rigid structure with a first surface and a second surface opposite to the first surface, and a piezoelectric ceramic structure bonded on the second surface through adhesive, wherein the piezoelectric ceramic structure is provided with at least a hole to increase the amplitude of first surface by adjusting the shape or size of the hole, and the hole area of piezoelectric ceramic structure is smaller or equal to half the total area of adhesive surface between the piezoelectric ceramic structure and the rigid structure plus the hole area. |
