AI Technical Summary
Conventional lens actuators face limitations in miniaturization, weight reduction, and efficiency due to the use of thin magnets with assembly errors, magnetic field leakage, and heat dissipation issues, which affect autofocus and image stabilization performance.
A magnetic flux generating component comprising first and second magnetic parts with opposite magnetization directions on the same plane, integrated with a soft magnetic material to concentrate magnetic flux and enhance driving force, and a sensor and actuator design that utilizes this component for precise position and orientation control.
The solution provides a small, lightweight, and highly efficient actuator with improved magnetic flux density, reduced magnetic leakage, and enhanced responsiveness for autofocus and image stabilization, enabling precise feedback control and miniaturization.
