The diaphragms (4, 5, 6, 7) are each warped to oscillate due to expansion and contraction of the piezoelectric layer or due to an oscillatory force from the outside. The diaphragms have mutually different resonance frequencies. A casing (2) has an internal space (2C) for accommodating the diaphragms (4, 5, 6, 7) and a fixing part (2D) for fixing a portion of each of the diaphragms (4, 5, 6, 7). The casing (2) transmits oscillations between the diaphragms (4, 5, 6, 7) and the outside via the fixing part (2D)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vibration device","description":"Diaphragms (4, 5, 6, 7) each include laminated layers including a piezoelectric layer.
