Abstract
An image stabilizer includes a stationary frame with four sidewalls, a moveable frame including four side panels, magnets, a plurality of fine pattern coils, and a resilient plate holding the moveable frame in the stationary frame. Each sidewall includes a receiving hole, a support portion received in the receiving hole, and a raised engagement portion extending from the support portion. The magnets are fixed on the side panels. The fine pattern coils are fixed in the receiving holes and aligned with the magnets and compensate for vibration and movement of the device to which it is affixed. The resilient plate is configured for returning the moveable frame to a resting position when a power supply is cut off.
