Brief description of the drawings
Fig. 1 is double schematic diagrames for taking the photograph voice coil motor provided by the utility model；
Fig. 2 is that double shown in Fig. 1 take the photograph the set of permanent magnets of voice coil motor and the schematic diagram of the sense of current.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of pair is taken the photograph voice coil motor, including first base 1, second base 2 and shell 3, first bottom
Seat 1 and second base 2 are set up in parallel, and the shell 3 is set in the first base 1 and second base 2 empty to form installation
Chamber；First mover, the second mover and set of permanent magnets are installed, first mover is arranged on described first in the installation cavity
On base 1, second mover is arranged in the second base 2, and the set of permanent magnets is distributed in first mover and
The surrounding of two movers.
This pair is taken the photograph voice coil motor and is respectively used to using the first base 1 and second base 2 being set up in parallel described in carrying
First mover and the second mover, it is split type, and the first base 1 and between the first base 1 and second base 2
Two bases 2 are the existing bases for singly taking the photograph voice coil motor, and producer can be by the first base 1 or second base 2, first
Mover or the second mover and camera lens etc. are changed, and are taken the photograph module to produce the double of different shooting effects, are improved compatibility
And usage experience.
The He of the first perforate 31 for corresponding respectively to first mover and the second mover is offered on the top surface of the shell 3
Second perforate 32.
First mover include be arranged in the first base 1 first vector 4, set be connected to it is described first carry
First time shell fragment 5, setting between body 4 and first base 1 are connected to first between the first vector 4 and the top surface of shell 3
