Vibration control device for vibration of gyroscopes.

摘要

A vibration control apparatus capable of setting the frequency of self-oscillating or self-induced vibration of an oscillator to a frequency in near agreement with the mechanical series resonance frequency fs is provided. The apparatus comprises a vibrator having a single piezo-electric element on the side surface of a vibrator member having a resonance point, drive apparatus having signal output terminal that outputs the drive signal of vibrator, and feedback amplifier having signal input terminal and feedback input terminal. The signal input terminal of feedback amplifier is connected to signal output terminal of drive apparatus. The feedback input terminal is connected to one electrode of piezo-electric element. The other electrode of piezo-electric element is connected to ground.
