Title:
共振器と機械的分離モジュールとを含むデバイス
Document Type and Number:
Japanese Patent JP5830091
Kind Code:
B2
Abstract:
The device (10) comprises a cylindrical resonator (R) vibrating in extension-compression along its longitudinal axis (Δ) and having a vibration node (N) in its mid-plane (π), the vibration naturally generating radial extension/compression deformations, and a mechanical decoupling module comprising a hollow cylinder (2) surrounding the resonator and a membrane (1) positioned in the aforementioned mid-plane and rigidly connected to the cylindrical surface of the resonator and to the internal cylindrical surface of the hollow cylinder. The hollow cylinder vibrates in extension/compression in antiphase with the vibration of the resonator, enabling the effects of the radial deformations of the hollow cylinder and of the resonator to compensate each other in an area (ZF) located on the external surface of the hollow cylinder close to the mid-plane.
