The magnetite stated in yoke is correspondingly arranged；Also, when the coil is not powered on, the upper elastic slice and the lower elastic slice are equal
Planar deformation may be not present in horizontal；
The yoke and pedestal assembly position, and define to form an assembly space between the two；The carrier passes through two bullets
Piece is flexibly positioned in the assembly space on the thickness direction of voice coil motor.
Related content in above-mentioned technical proposal is explained as follows：
1., can by the combination assembling form of the first assembly and this two assembly of the second assembly in above scheme
It improves the assembly efficiency of voice coil motor and improves the yields of product.
2. in above scheme, " when the coil is not powered on, the upper elastic slice and the lower elastic slice are in horizontal put down
Deformation may be not present in planar ", therefore elastic slice is without precompression, it, can be upward by the effect of electromagnetic force on the one hand after motor energization
Or move downward, another aspect motor is not necessarily to overcome during exercise the precompression of elastic slice to do work, so as to reach rapid focus
Effect.
3. in above scheme, the contact portion of the first elastic tip of the lower end surface of the pedestal and the lower elastic slice is plane,
There is no the structures that such as boss makes lower elastic slice generation predeformation in this way.
4. in above scheme, there is a gap between the magnetite and the lower elastic slice.
The working principle and advantage of the utility model are as follows：
A kind of voice coil motor with new function of the utility model, in above-below direction by the first assembly and the second assembly
Assembling positions；First assembly includes yoke, magnetite and upper elastic slice；Second assembly includes carrier, coil, lower elastic slice
And pedestal；Through-hole is equipped in the pedestal of carrier, the bonding of pedestal upper surface positions the second elastic tip of upper elastic slice；Pedestal lower end surface
Bonding positions the first elastic tip of lower elastic slice, and the second elastic tip of lower elastic slice is positioned at pedestal top；The winding of carrier periphery is wired
Circle, coil are correspondingly arranged with magnetite；When coil is not powered on, upper elastic slice and lower elastic slice are in that horizontal planar change may be not present
Shape.
Compared to existing technologies, the utility model is by designing a novel voice coil motor, and elastic slice is without precompression, and one
Aspect can be moved upwardly or downwardly after motor energization by the effect of electromagnetic force, and another aspect motor is not necessarily to gram during exercise
The precompression acting of elastic slice is taken, so as to achieve the effect that rapid focus.
Therefore, the utility model preferably meets the requirement of user, improves the use feeling of user, and more save
Electricity extends the stand-by time of equipment.
