New Description: [New Technology Field] This creation is a lens actuator, especially an actuator that can be applied to the lens drive of a miniature image capture module. [Prior Art] y—The pre-held device is equipped with an image capture module, which is accompanied by a product market that requires better performance and smaller size for handheld devices. The higher quality and miniaturization of the dual importance of the improvement of the quality of the enamel 'on the one hand is to improve the quality of the arsenal, the handheld device group market trend by the VGA level of 3G million, gradually increase megapixels, two million, Three million vegans, even toward higher levels of the four or five. In addition to the improvement of the element, the clarity of the image is taken into consideration. So the handheld device is also imaged by the fixed focus. The focus is not π = 2 (the fourth) is based on the image of the object to produce clear = r In the film "Qing, the movement method of head movement is: 隹 in the tender linear actuation, etc. Two electric actuation and voice coil type setting = another combination of the image capturing module to make the electromagnetic field and the second expansion Ii There is an opportunity to reduce the overall size of the image capture module. However, at the same time, in order to obtain sufficient actuation force to drive the lens M320096 to move, a better magnetic circuit design is needed, so that a limited magnetic source can be effectively utilized to generate sufficient actuation force. The first picture of Mai Kao is a schematic diagram of the magnetic circuit structure of the conventional voice coil motor.

The magnetic circuit component of the conventional voice coil motor 1 provides a closed magnetic circuit for generating magnetic lines of force 15. The magnetic line 15 is driven by two non-ring type magnets (1) and (1) = surface, and is turned by the two non-ring type surface yokes 121, 122 to the inner annular wall of the bottom iron 13 by the air gap 14, and then via the bottom iron u $ Guided back to the lower surface of the two acyclic magnets (1), 112. The design utilizes two non-ring surface irons (2), 122 as the guide for the 112 divergent magnetic field lines 15 and achieves the effect of the magnetic field lines 5 to generate sufficient actuation force. The voice coil motor 1 just mentioned needs to use the light iron to guide the magnetic line 15 to the passing coil (not labeled) to achieve the effect of the actuation, the difficulty of the tooth, and at the same time, it is also limited; and he also has a bottleneck in the small 5L. .
