Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment 1
As it is shown in figure 1, the carrier 2 of a kind of voice coil motor, the centre of described carrier 2 is cylindrical hollow structure, uses
In carrying camera lens, the top of described carrier 2 is provided with the first dust ring 21 and prevents with being positioned at second outside described first dust ring 21
Dirt ring 22, is formed with the first groove 24 between described first dust ring 21 and the second dust ring 22.
First dust ring 21 is set on the top of carrier 2 and the second dust ring 22 can lengthen voice coil motor top enters dirt
Path, strengthens the dust-proof effect on voice coil motor top.
The bottom of described carrier 2 is provided with the 3rd dust ring 23.
Arrange in the bottom of carrier 2 that the 3rd dust ring 23 can lengthen voice coil motor bottom enters dirt path, strengthens voice coil loudspeaker voice coil
The dust-proof effect of motor bottom.
Embodiment 2
As Figure 1-4, a kind of voice coil motor, including base 1 and be arranged on described base 1 such as institute in embodiment 1
The carrier 2 stated, the outside of described carrier 2 is provided with coil 3, and the outside of described coil 3 is provided with magnet assembly 4.
