Camera module and mobile terminal

A mobile terminal, comprising a controller and a camera module,

• wherein the camera module comprises a base, a guide shaft, a first piezo assembly, a second piezo assembly, and a first optical assembly and a second optical assembly that are successively slidably connected to the guide shaft in an optical axis direction, wherein the guide shaft is fixedly connected to the base;
• the first piezo assembly comprises a first interior surface and a second interior surface that is diametrically opposed to the first interior surface, the first interior surface and the second interior surface co-operatively define an accommodating space, the first optical assembly is disposed within the accommodating space, the first piezo assembly comprises a first stator and a first driven element, the first stator comprises a first piezo element and a first fixing element that are fixedly connected, the first fixing element comprises a first cantilever, and the first cantilever 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 on the guide shaft;
• the second piezo assembly is connected between the base and the second optical assembly, or between the first optical assembly and the second optical assembly, the second piezo assembly comprises a second stator and a second driven element, the second stator comprises a second piezo element and a second fixing element that are fixedly connected, the second fixing element comprises a second cantilever, and the second cantilever is configured to amplify vibration generated by the second piezo element in an energized state, and cooperate with the second driven element to drive the second optical assembly to slide on the guide shaft;
• wherein the first stator and the second stator are electrically connected to the controller, to supply power to the first piezo element and the second piezo element.
