Claim 2:
3. The three-axis micromachined gyroscope as described in claim 1, wherein the drive electrode drives the first weight and the second weight to swing in same phase; the drive electrode drives the third weight and the fourth weight to swing in same phase; wherein, the swing of the first weight and the third weight are in anti-phase;
when the three-axis micromachined gyroscope receives the angular velocity in the first axis direction, the four weights all rotate around the second axis; an overturn of the first weight and the overturn of the second weight are in anti-phase; an overturn of the third weight and the overturn of the fourth weight are in anti-phase; the overturn of the first weight and the overturn of the third weight are in anti-phase;
when the three-axis micromachined gyroscope receives the angular velocity in the second axis direction, the four weights all perform a overturning movement around the flip axis; the flip axis passes through the swing center of the weight and is parallel to the first axis; the overturn of the first weight is in same phase with the overturn of the second weight, and the overturn of the third weight is in same phase with the overturn of the fourth weight; the overturn of the first weight and the overturn of the third weight are in anti-phase;
when the three-axis micromachined gyroscope receives an angular velocity that is perpendicular to the third axis direction of the first axis and the second axis at the same time, the four weights all move in the direction of the first axis; the movement of the first weight and the movement of the second weight are in anti-phase; the movement of the third weight and the movement of the fourth weight are in anti-phase; the movement of the first weight and the movement of the third weight are in anti-phase.
