Abstract: A camera module of minimal size but with zoom function includes a zoom assembly, a base, and a fixed focus assembly. The zoom assembly and the fixed focus assembly are fixed in the base. The zoom assembly is driven by piezoelectric element instead of voice coil motor and includes an actuator and an optical unit. The actuator defines a first receiving groove holding the optical unit in place over the first through hole. When powered, the piezoelectric element changes a shape of the optical unit to change a focal length of the zoom assembly. An electronic device including such a camera module is also provided.
