Abstract
Examples are disclosed herein that relate to linear magnetic actuators in camera devices. One example provides a camera device comprising an optical sensor, a lens positioned a variable distance away from the optical sensor, a linear magnetic actuator having a coil and a magnet configured for linear relative movement upon driving of current, and an actuator coupling structure. The actuator coupling structure couples the linear magnetic actuator to the lens, such that the lens moves in response to the movement of the linear actuator.
