Title
(EN) MEMS gyroscope and electronic product
(ZH) 一种MEMS陀螺仪及电子产品
Abstract
(EN) The utility model provides an MEMS gyroscope and an electronic product.The MEMS gyroscope comprises a substrate, a first annular piece, a second annular piece, a connecting assembly, a fixing piece, a second spoke and an electrode assembly, and the electrode assembly drives the first annular piece and the second annular piece to vibrate in the first direction and the second direction which are perpendicular to each other. And the vibration displacement of the first annular piece and the second annular piece in the direction that the included angle between the first annular piece and the first direction is 45 degrees or the included angle between the first annular piece and the second annular piece is 135 degrees is detected, the sensitivity of the gyroscope is improved through the characteristic that the geometric structure of the annular gyroscope is highly symmetrical, meanwhile, the rigidity is higher, the modal frequency is higher, and the anti-vibration characteristic is improved.
(ZH) 本实用新型提供了一种MEMS陀螺仪及电子产品,MEMS陀螺仪包括基底、第一环形件、第二环形件、连接组件、固定件、第二辐条及电极组件,通过电极组件驱动第一环形件及第二环形件沿相互垂直的第一方向和第二方向振动,并检测第一环形件及第二环形件沿与第一方向的夹角呈45度方向或与第一方向的夹角呈135度方向的振动位移,利用环形陀螺仪几何结构高度对称的特征,提高陀螺仪的灵敏度,同时具有更大的刚度,更高的模态频率,提高抗振动特性。
