Driving mechanism

A driving mechanism comprises a fixed part, a movable part used for bearing an optical element, and a driving assembly. The movable part can move relative to the fixed part, and the movable part has afirst resonance frequency relative to the fixed part. The driving assembly is used for driving the movable part to reciprocate in an angle range relative to the fixed part. 一种驱动机构，包括一固定部、用以承载一光学元件的一活动部以及一驱动组件。前述活动部可相对于前述固定部运动，且前述活动部相对于前述固定部具有一第一共振频率。前述驱动组件用以驱使前述活动部相对前述固定部于一角度范围内往复地运动。
