Abstract
A compact camera module includes multiple hollow cylinders, a voice coil motor and a torsion spring. An intervening cylinder is mounted on a base. An upright rail is disposed on the intervening cylinder and perpendicular to a support plane of the base. An inner cylinder has a zoom lens inside and at least one moving component, wherein the inner cylinder is disposed in a hollow space of the intervening cylinder and the moving component slides within the upright rail. An outer cylinder is disposed around the intervening cylinder. The outer cylinder has a sloping rotational rail supporting the moving component. A wire coil is secured around the outer cylinder. A torsion spring encircles the outer cylinder and is secured to the base and the wire coil at two ends. A magnet-generating device is disposed around the wire coil and secured on the base.
