Abstract

This paper presents the improvement of an asymmetric actuator for optical image stabilization in a mobile phone camera. The required specification was defined from typical hand vibrations. The actuator was designed to have an asymmetric shape to reduce its size, but this design caused several problems. These problems were analyzed, and a new electromagnetic component design that solved these problems was proposed. Detailed dimensions of proposed design were obtained through the design of experiments procedure. Simulation results show that the final model exhibited sufficient performance to satisfy the required specification.
