Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row elaborates.
As shown in Figures 1 to 4, the utility model discloses a kind of voice coil motor, and it includes what is set gradually from top to down
Yoke plate 1, upper shell fragment 2, support 3, lower shell fragment 4 and pedestal 5, pedestal 5 are in be combined together up and down with yoke plate 1, upper shell fragment 2, support 3
And lower shell fragment 4 is arranged on pedestal 5 and in yoke plate 1, support 3 can be in slip in yoke plate 1, the interior top of the top surface of support 3 and yoke plate 1
Upper shell fragment 2 is set between face, lower shell fragment 4 is set between the bottom surface of support 3 and the top surface of pedestal 5.The outer ring spaced set of the support 3
There are at least two magnetites 6, the pedestal 5 is provided with least two coils 7 of face magnetite 6, the magnetic induction line direction after each energization of coil 7
Magnetic pole with corresponding magnetite 6 is on same longitudinal axis.The periphery spaced set of the support 3 has at least the two of corresponding magnetite 6
Baffle plate 31, a wherein magnetic pole for each magnetite 6 are correspondingly arranged at the bottom surface of baffle plate 31 respectively.
A wherein magnetic pole for each magnetite 6 is fixed on the bottom surface of baffle plate 31, and the present embodiment is fixed on gear with the N poles of each magnetite 6
