Abstract
Some embodiments include a camera voice coil motor (VCM) actuator that includes an additive coil structure for shifting a lens along one or multiple axes. The additive coil structure may include a base portion configured to couple with a lens carrier and at least partially surround a perimeter of the lens carrier. In various examples, the additive coil structure may include folded portions that individually include a respective coil that is located proximate a respective magnet. According to various embodiments, the additive coil structure may be formed using an additive process.
