Electromagnetism resultant direction after energization be adjusted to generally facing or substantially backwards to spring center 170.When diamagnetic interference parallel-moving type light
Learn stabilization voice coil motor 100 optical axis 180 it is upward when, the direction of the resultant force can be tilted upward or diagonally downward.Because
Moment arm (the d in such as Fig. 7,8 and 10 of each power1And d3) very small, so torque is also very small, apparent shifting axis will not be made
It tilts, reduces the influence to image edge resolution.Size of current by adjusting each coil 145 and direction can adjust
The size of the resultant force and direction, up to causing focusing (displacement in the directions z) and parallel-moving type optical anti-vibration (displacement in the directions x and y)
Effect.
By taking Fig. 8 as an example, the second magnet 154 acts on the electromagnetic force (F of coil 145t1), the first magnet 152 act on coil
145 electromagnetic force (Fb1) and the resultant force of two electromagnetic forces (be the F in attached drawing 81=Ft1+Fb1).Because of 154 He of the second magnet
The magnetic direction of coil 145 is consistent, so they attract each other, therefore Ft1Direction be generally facing the second magnet 154.On the contrary
The magnetic direction of ground, the first magnet 152 and coil 145 is on the contrary, so they are mutually exclusive, therefore the direction of Fb1 is substantially to carry on the back
To the first magnet 152.
It, can be with resultant force in each coil 145 of independent control by controlling the size of electric current and direction in four coils 145
Size and direction, the translation of both direction (directions x and y, for optical anti-vibration) and one can be made to controlling camera lens along light
The displacement (directions z, for auto-focusing) of axis 180.Because the resultant force size of each coil 145 is very close, own
The direction of total resultant force of coil 145 is balanced with optical axis 180, enables camera lens carrier 140 along optical axis displacement, up to the effect for causing auto-focusing
Fruit.In the above example, described since the position of the size and coil 145 of the first magnet 152 and the second magnet 154 is optimised
Moment arm (the d of two resultant forces1,d3) very small, therefore their torque (τ1=| | F1||×d1,τ3=| | F3||×d3) very small,
The apparent axis that moves will not be made to tilt, the influence to image edge resolution can be reduced.
In addition, in other embodiments, also pressure ring can be omitted.In other embodiments, displacement biography can be further increased
Sensor, such as hall effect sensor allow to drive diamagnetic interference parallel-moving type optical anti-vibration voice coil horse using close-loop control mode
Up to 100, up to cause auto-focusing or optical anti-vibration effect.
