  • Vibration unit having a piezoelectric element as the vibration source
    Patent number: 11323046
    Abstract: In a vibration unit, a piezoelectric element enters an internal space of a through hole; and thereby, a second case member can be arranged proximate to a first case member. Therefore, a thickness of the vibration unit can be reduced, namely, a height of the vibration unit can be reduced. As described above, since the thickness of the vibration unit is reduced, a size of the vibration unit can be reduced.
    Type: Grant
    Filed: September 13, 2018
    Date of Patent: May 3, 2022
    Assignee: TDK CORPORATION
