Soft magnetic materials is high-permeability material, and initial permeability is more than 500, sets interior atoms to arrange by manufacturing process
Cloth so that its maximum permeability can be more than 5000.In the utility model embodiment, magnetic conductivity is relative permeability, immeasurable
Guiding principle.
Soft magnetic materials is the change that can respond rapidly to external magnetic field, and is the material of energy low-loss acquisition high magnetic flux density
Material, easily can both be magnetized by externally-applied magnetic field, and easily demagnetization.Therefore, soft magnetic materials have larger initial permeability with
And maximum permeability is higher, coercivity H is smaller, and saturation induction density Ms is higher, and power consumption P is relatively low, and high stability etc. is excellent
Point.In general coercivity HC is less than 100A/m., can be preferable as magnetic shielding device because soft magnetic materials has above-mentioned advantage
Realize magnetic screen.
When the magnetic shielding device 14 has multiple soft magnetic materials housings, multiple soft magnetic materials housings are successively
Nesting, there is gap between the two neighboring soft magnetic materials housing.Optionally, the soft magnetic materials housing be silicon steel housing or
It is permalloy housing.The number of soft magnetic materials housing can be set according to demand, such as set 2 or 3, or it is any more
It is individual.
When the magnetic shielding device 14 has a soft magnetic materials housing, its structure is as shown in Fig. 2 Fig. 2 is this practicality
The structural representation for another magnetic shielding device that new embodiment provides, magnetic shielding device shown in Fig. 2 have a soft magnetism material
Material shell body 141, on substrate 11, the soft magnetic materials housing 141 has cavity 31.
When the magnetic shielding device 14 has multiple soft magnetic materials housings, its structure is as shown in figure 3, Fig. 3 is this practicality
The structural representation for another magnetic shielding device that new embodiment provides, magnetic shielding device shown in Fig. 3 have multiple soft magnetism materials
Material shell body 141, on substrate 11, the soft magnetic materials housing 141 has cavity 31.Multiple soft magnetic materials housings 141 are successively
Nesting, there is gap between the two neighboring soft magnetic materials housing 141.In Fig. 3 illustrated embodiments, the magnetic shielding device
With two soft magnetic materials housings 141.
The magnetic shielding device 14 using and magnetic shielding principle, the side wall of soft magnetic materials housing 141 with cavity 31
Air can regard magnetic circuit in parallel as, because the relative permeability of air is close to 1, and the side wall of soft magnetic materials housing 141
Magnetic conductivity it is larger, so the magnetic resistance of empty chamber air is more much bigger than the magnetic resistance of the side wall of soft magnetic materials housing 141.So,
The overwhelming majority will be along soft magnetism material in the magnetic induction flux in the magnetic field of two camera modules of the both sides of magnetic shielding device 14
The side wall of material shell body 141 is by the way that and then the magnetic flux in cavity is seldom, realizes magnetic screen, avoids two shootings of both sides
Magnetic disturbance between head mould group, improves image quality., can be by individual when with multiple soft magnetic materials housings 141
The soft magnetic materials housing 141, the magnetic flux leaked into cavity 31 masking again and again.
In the utility model embodiment, in first camera module 12 and the line of the second camera module 13
On direction, the thickness of the magnetic shielding device 14 is more than 0.2mm.The thickness of the magnetic shielding device 14 is bigger, its magnetic screen effect
Fruit is better, and the specific thickness of the magnetic shielding device 14 can take into account value with local Magnetic Shielding Effectiveness and small product size,
Its specific thickness is not limited in the utility model embodiment.
In the utility model embodiment, first camera module 12, the second camera module 13 and described
Magnetic shielding device 14 is located at the same side of a substrate 11.First camera module 12 and the second camera module 13
Permanent magnet is respectively provided with, on the direction of the substrate 11, the height of the magnetic shielding device 14 is not less than the permanent magnetism
The height of body so that the permanent magnet is located in the magnetic shielding device 14 in the upright projection of the magnetic shielding device 14, makes
The magnetic line of force for obtaining permanent magnet mainly concentrates that last described surface of magnetic shielding device 14, to avoid leakage magnetic field, ensures magnetic cup
Cover effect.
In Fig. 1-Fig. 3 illustrated embodiments, the first camera module 12 and the common substrate 11 of second camera module 13, tool
Body, the first camera module 12 and second camera module 13 can share a large-sized substrate 11.
With reference to figure 4, Fig. 4 is a kind of sectional drawing for dual camera module that the utility model embodiment provides, double shown in Fig. 4
In camera module, support 51 is fixed with the substrate 11, the support 51, which has, to be used to accommodate the first camera module 12
First chamber Q1 and second chamber Q2 for accommodating second camera module 13；Wherein, the magnetic shielding device 14 is solid
Fixed on the bracket 51.
In dual camera module shown in Fig. 4, the first camera module 12 and second camera module 13 are respectively adopted one
The substrate 11 of small size, is interfixed by support 51.The magnetic shielding device 14 is fixed on away from one end of the substrate 11
On support 15, in order to realize magnetic screen to the permanent magnet in camera module using the magnetic shielding device 14 of reduced size, this
It is because permanent magnet typically has a certain distance with substrate 11 in camera module so that magnetic shielding device 14 deviates from the base
One end of plate 11 is fixed on support 15, and magnetic shielding device 14 can be caused towards between one end of the substrate 11 and substrate 11
With gap, the size of reduction magnetic shielding device 14.
