Claim 1:
2. 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 anti-phase; the drive electrode drives the third weight and the fourth weight to swing in anti-phase; the swing of the first weight and the swing of 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 an overturn of the second weight are in same phase; an overturn of the third weight and an overturn of the fourth weight are in same 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 overturning movements around their respective 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 and the overturn of the second weight are in anti-phase; the overturn of the third weight and the overturn from 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 an angular velocity that is perpendicular to both the first axis and the third axis of the second axis, the four weights all move along the first axis; the movement of the first weight and the movement of the second weight are in same phase; the movement of the third weight and the movement of the fourth weight are in same phase; the movement of the first weight and the movement of the third weight are in anti-phase.
