Patent number: 11944999Abstract: A vibration device includes a bimorph type piezoelectric element having a first main surface and a second main surface facing each other and a vibration member bonded to the second main surface of the piezoelectric element. The piezoelectric element has a first active region disposed closer to the first main surface between the first and second main surfaces and a second active region disposed closer to the second main surface than the first active region between the first and second main surfaces. When a force generated in the first active region is F1, a force generated in the second active region is F2, and a force by which the vibration member restrains the second active region is Fr, F2?F1?Fr is satisfied.Type: GrantFiled: February 21, 2019Date of Patent: April 2, 2024Assignee: TDK CORPORATIONInventors: Yoshiki Ohta, Hideya Sakamoto, Kazushi Tachimoto, Yoshikazu Shimura, Tetsuyuki Taniguchi, Akihiro Takeda
