Zusammenfassung: | The invention provides an angular velocity sensor and a combined angular velocity sensor, and belongs to the technical field of sensors. At a first pre-designed frequency, the first pair of vibration modules moves synchronously and reversely. The second pair of vibration modules moves synchronously and reversely at a second pre-designed frequency in the direction of sensing mode movement. The drive mode mechanical amplification structure elastically couples the first pair of vibration modules to the motion frame to amplify motion of the first vibration module in its drive mode direction. The sensing mode mechanical amplification structure elastically connects the first pair of vibration modules and the second pair of vibration modules to amplify the movement of the first vibration module caused by the Coriolis force. Wherein the direction of the driving mode movement of the first pair of vibration modules is perpendicular to the direction of the movement of the movement frame, and the direction of the sensing |
