[0043] refer to figure 2 , 3 , 4, the lens driving mechanism 3 using electromagnets of the present embodiment comprises: a coil 31, a plurality of electromagnets 32, and the present embodiment is to use four electromagnets 32, and matching conductive sheets 33, coil electrodes 34. Electromagnet electrodes 35, etc.; wherein the plurality of electromagnets 32 are illustrated but not limited to four electromagnets 321-324, such as three electromagnets can be designed; The iron electrodes 351-354 are illustrated as examples but not limited, for example, they can be designed as a magnet electrode (the anti-vibration function cannot be achieved at this time). When in use, through the camera's controller (such as Figure 4 The controller 37) can control the output of the same or different direction (inflow or outflow) or the magnitude of the current, respectively input each electromagnet 32 (321 ~ 324) through the electromagnet electrode 35 (351 ~ 354); wherein, the coil 31 Sle...

[0048] refer to Image 6 , 7 , 8, the lens drive mechanism 3 using electromagnets in this embodiment includes: a coil 31, a plurality of electromagnets 32, and four electromagnets 32 are used in this embodiment. Wherein, the coil 31 is sheathed and fixed on the lens sleeve 22, and the ring body of the coil 31 relatively forms an outwardly protruding flange structure on the ring periphery of the lens sleeve 22, such as Image 6 , 7 As shown, that is, the coil 31 can be designed as a flat and wide shape to form a lower edge surface 311 with an appropriate radial width; At the lower edge surface 311 of the coil 31, and the electromagnet core 36 of each electromagnet 32 has a long arc section 362 to the arc of the lower edge surface 311 of the coil 31, and the long arc section 362 of the electromagnet core 36 The end is a corner to form a short vertical section 363, so that the end section 364 can face the lower edge surface 311 of the coil 31 vertically upwards; The number ...

[0053] refer to Figure 10 , 11 As shown, the lens drive mechanism 3 using electromagnets in this embodiment includes: a coil 31 and a plurality of electromagnets 32; wherein, the several electromagnets 32 (321-324) are arranged at intervals of 90 degrees at equal angles (three When two electromagnets 32 are promptly arranged with equiangular 120 degree intervals) are arranged on the outer edge surface 313 place near this coil 31, wherein, for reaching best effect, this coil 31 can be designed as long and narrow shape. The electromagnet core 36 of each electromagnet 32 (321~324) has a long arc section 365 with respect to the arc of the outer edge surface 312 of the coil 31 ring body, so as to reduce the occupied area of the electromagnet, and the electromagnet core The end of the long arc section 365 of 36 is a corner to form a short radial section 366, so that its end section 367 turns from the tangential direction to the radial direction to face the outer edge surface 3...
