MODULE FOR THE MECHANICAL UNCOUPLING OF A RESONATOR HAVING A HIGH QUALITY FACTOR

摘要

The invention relates to a device (10) comprising: a cylindrical resonator (R) vibrating in extension/compression along a longitudinal axis (?) and having a vibration node (N) in the mid-plane (p) thereof, said vibration naturally generating radial extension/compression deformations; and a mechanical uncoupling module comprising a hollow cylinder (2) surrounding the resonator and a membrane (1) disposed in the aforementioned mid-plane and rigidly connected to the cylindrical surface of the resonator and internal cylindrical surface of the hollow cylinder. The hollow cylinder vibrates in extension/compression in phase opposition with the vibration of the resonator, such that the effects of the radial deformations experienced by the hollow cylinder and the resonator offset one another in an area (ZF) located on the external surface of the hollow cylinder close to the mid-plane.
