This paper proposes a voice coil motor (VCM) with a novel electromagnetic structure for smartphone OZ actuators, and the advantages of this novel design are its long displacement, compact size, and more powerful and stable Lorentz force. These advantages are achieved by the novel electromagnetic structure that consist of L-shape coils. Its performances were verified by a laboratory-built prototype, and the experimental results (Lorentz force FVCM, response time, and zoomed images) can prove the proposed VCM actuator is feasible and vigorous.
