Abstract

This application provides a mobile terminal including a first magnet and a second magnet. At least a part of the first magnet and at least a part of the second magnet are disposed in the accommodating space. The first magnet is disposed on a back facet of the display module, the second magnet is disposed on the middle frame, and positions of the first magnet and the second magnet are disposed opposite to each other. The first magnet is a coil, and the second magnet is a main magnet; or the first magnet is a main magnet, and the second magnet is a coil. The main magnet is a Halbach array, and the main magnet generates a unilateral magnetic field on a side opposite to the coil.

Claims (46)

1. A mobile terminal, comprising:

a middle frame and a housing;

a display module disposed on the middle frame, wherein an accommodating space is formed between the display module and the middle frame; and

a first magnet and a second magnet, wherein at least a part of the first magnet and at least a part of the second magnet are disposed in the accommodating space; and

the first magnet is disposed on a back facet of the display module, the second magnet is disposed on the middle frame, and positions of the first magnet and the second magnet are disposed opposite to each other, wherein

the first magnet is a coil, and the second magnet is a main magnet; or the first magnet is a main magnet, and the second magnet is a coil; and

the main magnet is a Halbach array to generate a unilateral magnetic field on a side opposite to the coil.

2. The mobile terminal according to claim 1 , wherein a part of the main magnet is embedded in a closed region wound by a wire of the coil.

3. The mobile terminal according to claim 2 , further comprising:

an auxiliary magnet located on a same side as of the main magnet;

a gap formed between the auxiliary magnet and the main magnet, wherein a part of the coil is located in the gap between the auxiliary magnet and the main magnet.

4. The mobile terminal according to claim 2 , further comprising a washer, wherein

when the first magnet is the main magnet, the washer is located on a surface of a side of the main magnet that is away from the display module; or

when the second magnet is the main magnet, the washer is located on a surface of a side of the main magnet that is away from the middle frame.

5. The mobile terminal according to claim 2 , further comprising a magnetic bowl to carry the main magnet, wherein

when the second magnet is the main magnet, the magnetic bowl is located on a surface of a side of the main magnet that is away from the display module.

6. The mobile terminal according to claim 1 , wherein the main magnet is located outside a closed region wound by a wire of the coil; and

opposite surfaces of the main magnet and the coil are parallel.

7. The mobile terminal according to claim 6 , further comprising:

an auxiliary magnet located on a same side as of the coil, wherein the auxiliary magnet is embedded in the closed region wound by the wire of the coil.

8. The mobile terminal according to claim 7 , wherein opposite sides of the auxiliary magnet and the main magnet are a same magnetic pole.

9. The mobile terminal according to claim 6 , further comprising a magnetic conductive plate, wherein

when the first magnet is the main magnet, the magnetic conductive plate is located on a surface of a side of the main magnet that is away from the display module, or the magnetic conductive plate is located on a surface of a side of the auxiliary magnet that is away from the middle frame; or

when the second magnet is the main magnet, the magnetic conductive plate is located on a surface of a side of the main magnet that is away from the middle frame, or the magnetic conductive plate is located on a surface of a side of the auxiliary magnet that is away from the display module.

10. The mobile terminal according to claim 6 , further comprising a coil magnetic shield, wherein

all surfaces other than at least a surface of a side of the coil facing the main magnet are wrapped by the coil magnetic shield.

11. The mobile terminal according to claim 10 , further comprising a first magnetic shield, wherein

all surfaces other than a surface of a side of the main magnet facing the coil are wrapped by the first magnetic shield.

12. The mobile terminal according to claim 1 , wherein the main magnet comprises a first main magnet part and a second main magnet part that is annular and nested on the first main magnet part, wherein

a magnetic pole direction of the second main magnet part is perpendicular to a magnetic pole direction of the first main magnet part.

13. The mobile terminal according to claim 1 , further comprising:

a support disposed on a surface of a side of the middle frame that is away from the display module;

a hole disposed on the middle frame, wherein

at least a part of the second magnet is located in the hole on the middle frame, and

the second magnet passes through the hole on the middle frame and is disposed on the support.

14. The mobile terminal according to claim 13 , further comprising a spring plate and a support block located in the hole on the middle frame, wherein

the spring plate is located between the second magnet and the support, and the spring plate is connected to the second magnet; and

the support block is disposed between the spring plate and the support, and an upper surface and a lower surface of the support block are respectively connected to the spring plate and the support.

15. The mobile terminal according to claim 1 , further comprising a spring plate and a support block, wherein

the spring plate, the support block, the first magnet, and the second magnet are all located in the accommodating space;

the spring plate is located between the second magnet and the middle frame, and the spring plate is connected to the second magnet; and

the support block is disposed between the spring plate and the middle frame, and an upper surface and a lower surface of the support block are respectively connected to the spring plate and the middle frame.

16. The mobile terminal according to claim 1 , further comprising a support plate including

an upper surface connected to the display module; and

a lower surface connected to the first magnet, wherein

an area of the upper surface of the support plate is larger than an area of a surface of a side of the first magnet that is close to the support plate.
