Abstract
(EN)
Provided is a vibration device that can suppress leakage and damping of vibrations. This vibration device 1 is provided with: a vibration element 2 that has a cylindrical vibrator 3 including a first open end face 3a and a second open end face 3b; a support 15, which, when the axial direction is defined as a direction connecting the first open end face 3a and the second open end face 3b of the vibrator 3, extends in the axial direction and supports the vibrator 3; and a connection member 14 that connects the vibrator 3 to the support 15. The vibrator 3 performs breathing vibration so as to generate a first node and a second node at different positions in the axial direction of the vibration element 2 and the connection member 14 is positioned between the first node and the second node.

L'invention concerne un dispositif de vibration qui peut supprimer la fuite et l'amortissement de vibrations. Ce dispositif de vibration 1 est pourvu : d'un élément de vibration 2 qui comprend un vibreur cylindrique 3 comprenant une première face d'extrémité ouverte 3a et une seconde face d'extrémité ouverte 3b ; d'un support 15, qui, lorsque la direction axiale est définie comme étant une direction reliant la première face d'extrémité ouverte 3a et la seconde face d'extrémité ouverte 3b du vibreur 3, s'étend dans la direction axiale et supporte le vibreur 3 ; et d'un élément de liaison 14 qui relie le vibreur 3 au support 15. Le vibreur 3 effectue une vibration de respiration de façon à générer un premier noeud et un second noeud à différentes positions dans la direction axiale de l'élément de vibration 2 et l'élément de liaison 14 est positionné entre le premier noeud et le second noeud.
