Four translation coils are set evenly, and the magnetite is 4 pieces, are arranged in correspondence with yoke with the translation coil position respectively
On four inwalls, it is identical towards the polarity of focusing coil side.Two translation coils series connection or each flat on diagonal
Move coil separate.
Additionally, the support of the present invention can mitigate the weight of member of translational using the plastic rubber bracket of lighter in weight.
The voice coil motor of the present invention is OIS motors, and by five fitting coils four magnetites around coil are assemblied in, can
Realize that the focusing to camera lens and controllable levels are moved, and the voice coil motor production part is few, production yield is high, is carrying out translation fortune
When dynamic, due to moving component it is few and very light, therefore low in energy consumption, volume production preferably.
Description of the drawings
Below, the present invention is described in detail for control accompanying drawing and preferred embodiment, wherein：
Fig. 1 is the explosive view of the present invention；
Fig. 2 is the sectional view of the present invention.
Specific embodiment
Invention is described in detail with reference to the accompanying drawings and examples.It should be appreciated that the explanation to specific embodiment
Only to explain technical scheme proposed by the present invention, and the non-limiting present invention.
Fig. 1, Fig. 2 give one embodiment of the invention, and in this embodiment, the voice coil motor of the present invention includes：Lower cover
10th, metal yoke 1, the lens mount 3 with camera lens, magnetite 9, focusing coil 5, translation coil 6, fixing device, fixing device is used for
Fixed mirror headstock, it is limited in lens mount 3 in a plane of optical axis, and drives lens mount 3 to carry out in the plane
Translational motion.Fixing device includes support 7, suspension 4 and spring leaf.
Lens mount 3 is set with focusing coil 5 near the periphery of the one end of lower cover 10, and the periphery of the other end is arranged evenly and at intervals
Four translation coils 6, magnetite 9 is provided with 4 pieces, be arranged in correspondence with four inwalls in yoke with translation coil 6 position respectively
On, it is identical towards the polarity of focusing coil 5 side.Two coils that translation coil 6 is located on diagonal can connect, or
Four translation coils 6 can also be separate.
Support 7 has a cavity, and in the cavity of support 7, the one end near yoke is by upper spring leaf 2 for lens mount 3
Fix with the upper end of support 7, the one end near lower cover 10 is fixed by lower spring piece 8 with the lower end of support 7, the side of the surrounding of support 7
The position of face correspondence translation coil 6 is provided with opening, will not stop the interaction of each coil and magnetite 9, and support 7 is away from upper lid
One end, is connected by the traction of suspension 4 with lower cover 10.Suspension 4 is used for the motion of control focusing part-structure, and it can be adopted bullet
