Abstract
The technology of this application relates to a voice coil motor, a camera module, and an electronic device. The voice coil motor includes a base, a slide rail assembly, disposed in front and rear directions, a movable base, configured to carry a first lens and slidably disposed on the base through the slide rail assembly, and a first electromagnetic drive assembly and a second electromagnetic drive assembly, configured to supply driving force to the movable base, to drive the movable base to slide in the front and rear directions of the base. The first electromagnetic drive assembly and the second electromagnetic drive assembly are respectively disposed on two sides of the slide rail assembly.
