Description

Technical Field

[0001] The utility model relates to the technical field of gyroscopes, in particular to a dual-axis micro-mechanical gyroscope. Background Art

[0002] A micromechanical gyroscope is a gyroscope manufactured based on micromechanical technology. Since there is no need to integrate rotating parts inside, but instead a vibrating micromechanical component made of silicon is used to detect angular velocity, micromechanical gyroscopes are very easy to miniaturize and mass-produce, and have the characteristics of low cost and small size. Dual-axis micromechanical gyroscopes include types that can detect pitch and roll directions, as well as types that can detect pitch and yaw directions. However, dual-axis micromechanical gyroscopes are easily affected by high-frequency vibrations when in use, resulting in a decrease in the accuracy of the gyroscope.
