Abstract
Disclosed herein are a driving mechanism, a camera module and an electronic device. The driving mechanism includes: a driving component, a movable assembly, and a fixed assembly, wherein the driving component includes an elastic conductor element, a closed circuit, and a magnetic element; wherein the closed circuit is located in a magnetic field generated by the magnetic element, and is configured to communicate with the elastic conductor element to generate an electromagnetic force for overcoming an elastic force of the elastic conductor element; and wherein the elastic conductor element is fixedly connected with the fixed assembly, and is abutted against the movable assembly; and the elastic conductor element is configured to drive the movable assembly to move relative to the fixed assembly during a focusing function in response to determining that the electromagnetic force is greater than the elastic force of the elastic conductor element.
