Abstract
The present invention provides a micromachined gyroscope, including: a base; an anchor point fixed to the base; a number of vibration structures; and a drive structure used for driving the vibration structure to vibrate in a x-y plane along a ring direction. The drive structure includes at least four groups arranged at intervals along the ring direction and symmetrical about an x axis and a y axis. The micromachined gyroscope works in two vibration modes interchanging with each other, including a driving mode status working in a first mode status and a testing mode status working in a second mode status. By virtue of the configuration described in the invention, the micromachined gyroscope can realize three-axis detection at the same time, and greatly improves the quality utilization rate of the vibration structure.
