Abstract
A micromechanical gyroscope and an electronic device are related. The micromechanical gyroscope includes a first movement member, a second movement member, many drive members and a detection member, the first movement member has a first center, with two ends along a second direction oscillating around the first center along a first and a third directions, the second movement member has a second center, with two ends along the first direction oscillating around the second center along the second and third directions. The drive members can drive oscillations of the first and second movement members. The detection member is located above or below the first and second movement members in the third direction, to detect moving distances of the first and second movement members along the third direction. The micromechanical gyroscope can detect angular velocities in two directions simultaneously and perform differential detection to reduce errors, thus expanding application scenarios.
