In the present creation, the plurality of drive coils 14a, 14b, 14e, 14d and the plurality of permanent magnets 16a, 16b, 16e, 16d, 16e, 16f substantially constitute a set of electromagnetic drive mechanisms, and the yokes 13a, 13b, 13c, 13d provides a function of guiding magnetic force; wherein one of the driving coils and the permanent magnets is combined and annularly distributed around the lens carrier, and the other is coupled and ring-shaped. The lens is mounted on the housing, and by applying a predetermined current to the driving coils, the lens carrier can be rotated relative to the housing. In this embodiment, the 12 M336455 multi-segment lens driving module ίο includes four sets of the driving coils 14a, 14b, 14c, 14d and corresponding to the four sets of the yokes 13a, 13b, 13c, 13d, respectively. And electromagnetic induction with the permanent magnet 16. The permanent magnet 16 system further includes six groups 16a, 16b, 16c, 16d, 16e, 16f, and an average annular distribution is embedded around the lens carrier 15. Due to the alternating change of the input current directions of the respective drive coils 14a, 14b, 14c, 14d, the permanent magnets 16a, 16b, 16c, 16d, 16e, 16f and the set of irons 13a, 13b, 13c, 13d can be respectively arranged. Producing a phenomenon of homopolar repulsion or heteropolar attraction of different magnetic properties (N pole or S pole), the lens carrier 15 is reciprocally displaced in the accommodating space 118 along the central axis 50 direction, thereby The reciprocating linear displacement of the lens carrier 15 in a six-segment position is achieved. When the driving coils 4a, 14b, 14c, 14d are not subjected to current, they may be separated from the yokes 13a, 13b, 13c, 13d by the permanent magnets 6a, 16b, 16e, 16d, 16e, 16f, respectively. Attraction, the lens carrier 15 is attracted to a predetermined position to make it difficult to shake. Similarly, when the lens carrier 15 is moved to other respective segments, the current input by the driving coils 14a, 14b, 14c, and 14d can be cut off after the displacement conversion of any of the segments is completed, and respectively The permanent magnets 16a, 16b, 16c, 16d, 16e, 16f and the magnetic forces between the irons 13a, 13b, 13c, and 13d are attracted to each other to achieve a power saving function.
