An outer edge of one kind of piezoelectric actuator fixed laser processing and preparation method polycyclic gyroscope

The present invention provides a laser processing the outer edge of the piezoelectric driving fixed polycyclic gyroscope and its preparation method, comprising: a multiple ring resonator containing five to eight ring; a fixed chute supporting multiple ring resonator; located in the a plurality of sets of said plurality of spokes between two adjacent ring resonators for the rings are connected to the multiple ring resonator, the two adjacent spokes at an angle to the position difference; a multiple ring resonator surface electrode; wherein: the multiple ring resonator outermost circle ring is fixed, leaving only the free radial vibration. Electrode of a piezoelectric material, a piezoelectric driving method when the gyro work. Since the present invention is fixed to an outer edge of the multiple ring resonator, the ring electrode is built in the center, with a small, stable structure, sensitive response, etc., with good symmetry, it is possible to achieve high performance.
