ABSTRACT:
A digital camera module (100) with an auto-focusing function is adapted for use in a foldable electronic device. The digital camera module includes a lens mount (10), a lens barrel (20), a voice coil actuator (40), and an image pick-up module (50). The lens barrel receives at least one lens (24) therein and is mounted on/in the lens mount. The lens barrel is made of a composite material including a magnetic metallic nano-powder. The voice coil actuator is adapted for cooperating with the lens barrel to form a magnetic loop. The image pick-up module is disposed under the lens mount and is configured for receiving an image from the at least one lens and converting that image to an electrical signal.
