When the coil 29 is energized to generate a magnetic field, the magnetic field of the magnetic portion 23 itself repels the effect, and the base 21 is pushed to be displaced, so that the magnetic member 28 and the magnetic conductive member 22 are attracted together. When a positive voltage current passes through the coil 29, the magnetic force pushes the base 21 forward (in the direction of arrow 60), causing the magnetic element 28 to attract the magnetically permeable element 22, which will stabilize the lens 3, and when the negative voltage current passes through the coil 29 At this time, the magnetic force pushes the base 21 backward (in the direction of the arrow 61), so that the magnetic element 28 and the magnetic conductive element 22 attract each other to achieve the focusing operation, and the focus of the micro lens becomes the two-stage driving focus. As shown in FIG. 4 , the multi-segment focusing structure of another embodiment includes a pedestal 41 , a plurality of magnetic guiding elements 42 , a plurality of magnetic parts 43 , a frame 44 , and a front cover 45 . A bottom cover 46, a housing 47 and a plurality of elastic members 48. The base 41 has a plurality of magnetic elements 49, a coil 50 and a lens 51. The base 41 is disposed at the center of the frame 44. The lens 51 is mounted at the center of the base 41. The coil 50 is coated on the base. Around the seat 41, the magnetic element 49 is disposed on the frame 44 and is located one behind and behind the base 41. The magnetic conductive component 42 is disposed on the front cover 45 and the bottom cover 46, and is located in front of and behind the magnetic component 49 and the elastic component 48, and maintains a section that cannot mutually absorb M316412. The magnetic component 43 is disposed around the frame 44. So that it is just in place, and the surrounding and 'severing-segment can make the electric field have a fixed distance of effect. The rear side and the elastic member 48 are electrically conductive materials, and are disposed before the frame 44, and the element 42 and the miscellaneous member 49n cover all of the members, but the lens 51 can be exposed according to the situation. Power-on is a schematic cross-sectional view of Figure 4. When the coil 50 2 is in contact with the magnetic field of the magnetic portion 43 itself, the displacement is purely generated, so that the impurity element 49 and the guide member 42 can be together. In addition, the elastic member 48 forms a conduction loop with the coil 5, and the base 41 can be fixed at any position. When the current of -5^正€>1 passes through the coil 5G, the magnetic force pushes the base 41 forward (the arrow causes the magnetic element 49 to attract the magnetic conductive element 42, which will stabilize the lens 51, although the negative voltage current passes through the coil At 5 ,, the magnetic push base is moved backwards (in the direction of arrow 63)' by the elastic force of the elastic member 48, and can be moved to any position; when the current of the negative electric dust is applied through the coil 50, the magnetic force pushes the base 41 backward ( In the direction of the arrow 63), the magnetic element 49 is attracted to the magnetic conductive element 42 to achieve the focusing motion, so that the focus of the micro lens is transmitted through the design of the elastic element 48 to achieve three-stage driving-focusing. The pedestal 2 of the multi-stage focus driving structure is composed of a magnetic member, and there is no trouble that it is detached due to insufficient magnetic force; and the pedestal 2 and the magnetic member 28 are laterally fixed. On the frame 24 and the material, there will be no problem of dust generated by friction; in addition, after completing each segment of the focusing action, the power can be turned off to achieve the effect of power saving and low power. Using the techniques disclosed above, For a design that is different from the well-known person's ability to improve the overall use value, and before the application is not seen in the publication or public use, 'Cheng has met the requirements of the new patent, and filed a new M316412 patent application according to law.
