Magnet group 150 is fixed on the inwall of shell 160, the motionless structure of composition and magnet group 150, shell 160 and base 110 link together.The number of magnet group 150 is identical with the number of coil 145, and each magnet group 150 is all oppositely arranged with a coil 145.In one embodiment, the number of magnet group 150 can be 3,4 or more.Each magnet group 150 comprises the first magnet 152 and the second magnet 154.First magnet 152 and the second magnet 154 are folded on the direction being approximately perpendicular to base 110 to be established.Such as, as shown in Figure 7, the first magnet 152 is arranged on base 110, and the second magnet 154 to be arranged on the first magnet 152 and to contact with shell 160.The magnetic direction of the first magnet 152 and the second magnet 154 is contrary, and namely in the first magnet 152 and the second magnet 154, the magnetic direction of is towards camera lens carrier 140, and another is camera lens carrier 140 dorsad.Shape, the large I of the first magnet 152 and the second magnet 154 adjust according to actual needs, can be the same or different to meet the different needs.First magnet 152 and the second magnet 154 can be magnetite.
Above-mentioned is the concrete structure of diamagnetic interference parallel-moving type optical anti-vibration voice coil motor 100 in one embodiment of the invention, its principle of work of brief description.
As mentioned above, the body 141 of coil 145 and camera lens carrier 140 links together, composition bascule; Magnet group 150, shell 160 and base 110 link together and form motionless structure; Shell fragment 130 connection lens carrier 140 and motionless structure, can form a multivariant mass-spring system.As shown in figs 6-8, multivariant mass-spring system comprises a spring rotation center 170 (claiming spring center afterwards), and when there being a moment to be applied in described system, described system can be rotated around spring center 170; By adjusting the spring constant of each spring in mass-spring system, the position of spring center 170 can be adjusted.By adjusting the position of coil 145 and size shape, and the position of the first magnet 152 and the second magnet 154 and size shape, each coil 145 electromagnetism resultant direction after powered up can be adjusted.
When diamagnetic interference parallel-moving type optical anti-vibration voice coil motor 100 works, as shown in Fig. 7,8 and 10, each coil 145 electromagnetism resultant direction be after powered up adjusted to roughly towards or spring center 170 roughly dorsad.When diamagnetic interference parallel-moving type optical anti-vibration voice coil motor 100 optical axis 180 upwards time, described direction of making a concerted effort can be tilt upward or be tilted to down.Because the moment arm of each power is (as the d in Fig. 7,8 and 10
1and d
3) very little, so moment is also very little, can not makes and significantly move axle, reduce the impact on image edge resolution.By adjusting size of current and the direction of each coil 145, the size of making a concerted effort described in can adjusting and direction, reach the effect causing focusing (displacement in z direction) and parallel-moving type optical anti-vibration (displacement in x and y direction).
For Fig. 8, the second magnet 154 acts on the electromagnetic force (F of coil 145
t1), the first magnet 152 acts on the electromagnetic force (F of coil 145
b1), and two electromagnetic forces (is namely the F in accompanying drawing 8 with joint efforts
1=F
t1+ F
b1).Because the second magnet 154 is consistent with the magnetic direction of coil 145, so they are attracted each other, therefore F
t1direction be roughly towards the second magnet 154.On the contrary, the magnetic direction of the first magnet 152 and coil 145 is contrary, so they are mutually exclusive, therefore the direction of Fb1 is the first magnet 152 roughly dorsad.
By controlling size and the direction of electric current in four described coils 145, independently can control the size of making a concerted effort in each coil 145 and direction, thus control translation (x and the y direction that camera lens can make both direction, for optical anti-vibration), and a displacement along optical axis 180 (z direction, for auto-focusing).Because the size of making a concerted effort of each coil 145 is closely, so the direction of always making a concerted effort of all coils 145 balances with optical axis 180, makes camera lens carrier 140 along optical axis displacement, reach the effect causing auto-focusing.In the above example, due to the first magnet 152 and the size of the second magnet 154 and the position of coil 145 optimised, described two moment arm (d made a concerted effort
1, d
3) very little, therefore their moment (τ
1=|| F

3) very little, can not make and significantly move axle, the impact on image edge resolution can be reduced.
In addition, in other embodiments, also pressure ring can be omitted.In other embodiments, displacement transducer can be increased further, such as hall effect sensor, allow and use close-loop control mode to drive diamagnetic interference parallel-moving type optical anti-vibration voice coil motor 100, reach and cause auto-focusing or optical anti-vibration effect.
A kind of assembly method of this diamagnetic interference parallel-moving type optical anti-vibration voice coil motor 100 of brief description.This assembly method comprises:
Step S200: live wire is formed coil 145 on the wrapping post on camera lens carrier 140 and boss 143;
Step S202: shell fragment 130 is placed on below camera lens carrier 140, and make wrapping post below camera lens carrier 140 through the hole on shell fragment;
Step S204: shell fragment 130 and camera lens carrier 140 are mechanically connected;
Step S206: shell fragment 130 and live wire are carried out circuit connection;
Step S208: pressure ring 120 is placed on 130 sides under shell fragment, and is mechanically connected;
Step S210: be placed on by shell fragment 130 above base 110, is then mechanically connected shell fragment 130 and base 110, then is electrically connected with the conductive part on base 110 by shell fragment 130;
Step S212: magnet group 150 be fixed on the inwall of shell 160, is placed in shell 160 inner, and guarantees that each coil 140 is all relative with a magnet group 150 by camera lens carrier 140;
Step S214: the bottom of shell fragment 130 and the first magnet 152 is mechanically connected.
In step s 200, specifically can use the automatic winding method in Chinese patent CN104052214 by live wire around on the wrapping post on described camera lens carrier 140 and boss 143, composition coil 145.
Diamagnetic interference parallel-moving type optical anti-vibration voice coil motor 100 in one embodiment of the invention and assembly method thereof at least have a little following:
