Body extends to down be bent to form；
The lower cover includes the flat lid of a rectangle, offers a third through-hole in the middle part of the flat lid, should
Third through-hole and second through-hole are coaxially disposed；Wherein, the surrounding recess of the lower cap upper surface, it is fixed to form a rectangular ring
Position slot, the yoke are inserted into the cyclic annular locating slot with the bottom of its four side plate, and the inside patch of each side plate
The cell wall for closing the cyclic annular locating slot, reaches the assembly of the yoke Yu the lower cover；
Each side plate passes through viscose with the binding site of the cyclic annular locating slot and connect, reach the yoke with it is described
The positioning of lower cover.
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.
5. in above scheme, the binding site includes the bottom of each side plate and the slot bottom of the cyclic annular locating slot
Contact position further includes the inside and the contact position of the cell wall of the cyclic annular locating slot of each side plate.
6. in above scheme, the ring-type locating slot is located at the outer most edge of the lower cap upper surface, ring-type positioning is constituted
Slot only includes the cell wall of side inwardly.
The working principle and advantage of the utility model are as follows：
Compared to existing technologies, the utility model：
One, by designing a novel voice coil motor, elastic slice on the one hand after motor energization, can pass through without precompression
The effect of electromagnetic force is moved upwardly or downwardly, and another aspect motor is not necessarily to overcome during exercise the precompression of elastic slice to do work, thus
