Abstract: An electronic device may include a lens module with a tunable lens. The tunable lens may include multiple adjustable fluid-filled bladders distributed around the periphery of the tunable lens. Fluid may be selectively added to and removed from each adjustable fluid-filled bladder to control a displacement of a lens element at a given position along the periphery. The fluid may be added to and removed from the adjustable fluid-filled bladders by fluid-controlling components. The fluid-controlling components may be positioned locally within a ring-shaped chassis portion and adjacent to a respective bladder or may be consolidated in an additional chassis portion and connected to the bladders using fluid channels through the ring-shaped chassis portion. The fluid-controlling components may include stepper motors with two subassemblies that each have a ring-shaped magnet between two coils.

Abstract: An electronic device may include a lens module with a tunable lens. The tunable lens may include a flexible lens element and a lens shaping structure attached to the flexible lens element. The lens shaping structure may include a plurality of tabs that are each coupled to a respective actuator. The actuator may have a slot that receives the tab of the lens shaping structure and moves the tab up and down along an axis of displacement. The actuator may include two motor subassemblies that each have a ring-shaped magnet between two coils. The actuator may include a housing, a screw that is rotated by the motor subassemblies, a guide rod, and a nut with openings aligned with both the screw and the guide rod. The actuator may include a homing sensor with an electrode on the nut and at least one electrode on the housing.
