Honeycomb Disc Vibrating Top

Abstract

The invention provides a honeycomb-shaped disc-shaped vibrating gyro which comprises a harmonic oscillator and electrodes arranged in or / and outside the harmonic oscillator. The harmonic oscillator is in a disc shape which is overall in axisymmetry. The center of the disc-shaped harmonic oscillator is an anchoring point used for fixing the whole harmonic oscillator, and a circle of round harmonic rings are arranged on the outer edge of the disc-shaped harmonic oscillator. The structures for connecting the harmonic rings and the anchoring point are honeycomb-shaped frames which are distributed periodically in the circumferential direction and are in a honeycomb topology shape, a plurality of rings of hexagonal holes distributed periodically in the circumferential direction are formed in the honeycomb-shaped frames, and the whole honeycomb-shaped frames and a circular ring form a harmonic structure of the harmonic oscillator. The electrodes used for conducting driving, detecting and controlling can be arranged inside or outside the harmonic oscillator or arranged inside and outside the harmonic oscillator at the same time. The honeycomb-shaped disc-shaped vibrating gyro has the advantages that large harmonic mass is achieved, the number of driving electrodes is large, the detection capacitance area is large, and the number of control electrodes is large.

Description
