Abstract
A method of forming a vibrating gyroscope includes the steps of providing a vibrating body and disposing at least one driving member on the vibrating body so that the at least one driving member is arranged to generate vibration in the vibrating body in a vibrating direction that is substantially perpendicular to an axis of the vibrating body. Then, at least two detection members are disposed on the vibrating body such that the at least two detection members are spaced from each other, located on opposite sides of a plane including the axis and the vibrating direction of the vibrating body, arranged to detect a rotational angular velocity applied to the vibrating body and arranged in a non-parallel relationship relative to each other and in a non-parallel relationship relative to the at least one driving member.
