Abstract
An integrated structure of auto focus (AF) and optical image stabilizer (OIS) mechanisms includes a lens holder, a frame, magnets, suspension elements, and a driver board. The lens holder has an AF coil disposed outside thereof and is suspended in the frame. The inner edges of the sidewalls of the frame are close to but do not contact the outer edge of the AF coil. The magnets are disposed between the frame and the lens holder and correspond to the outer edge of the AF coil, for driving the lens holder back and forth along an optical axis (i.e. the Z axis). The suspension elements suspend the frame in the direction of the optical axis. The driving board has fine pattern coils each corresponding to one of the magnets, for driving the frame laterally (i.e. along the X-axis and/or Y-axis) with respect to the optical axis.
