Abstract: The present application discloses a camera module that includes a base, a guide shaft, a first piezo assembly, a second piezo assembly, a first optical assembly, and a second optical assembly. The first piezo assembly includes a first stator and a first driven element. The first stator includes a first piezo element and a first fixing element. A first cantilever of the first fixing element is configured to amplify vibration generated by the first piezo element in an energized state, and cooperate with the first driven element to drive the first optical assembly to slide. The second piezo assembly includes a second stator and a second driven element, and the second stator includes a second piezo element and a second fixing element. A second cantilever of the second fixing element cooperates with the second driven element to drive the second optical assembly to slide.
