1. An autofocus lens module, comprising:
- a holder defining a space;
a barrel positioned in the space of the holder;
a first post extended from an outer surface of the barrel;
a first spring connecting adjacent ends of the barrel and the holder such that the barrel is maintained in the holder; and
a first piezoelectric actuator fixed on an internal surface of the holder and being capable of deforming along a central axis of the holder, the first piezoelectric actuator coupled with the first post so as to move the barrel along the central axis of the holder.
