The magnetic body 43 may be located between the outer member 41 and the seal 45. The magnetic body 43 includes a material that can be attracted by a magnetic field, and the material that can be attracted by a magnetic field includes iron, cobalt, nickel, etc., and the magnetic body 43 may be a steel sheet, a neodymium-iron-boron magnet 31, etc., and the first magnetic force generated by the magnet 31 attracts the magnetic body 43, thereby fixing the exterior assembly 40 to the housing 10.

The sealing member 45 is located at a side of the magnetic body 43 facing away from the exterior member 41, and the sealing member 45 can be used to prevent external moisture and dust from entering the inside of the terminal device 100.

The terminal device 100 further includes a spring 70, and the coil 33 is electrically connected to the circuit board 60 through the spring 70.

The process of installing and removing the exterior component 40 of the terminal device 100 provided in the present embodiment is described in detail below.

When the appearance component 40 needs to be installed, the appearance component 40 is placed in the decoration 20, the magnet 31 adsorbs the magnetic body 43 in the appearance component 40 under the action of the first magnetic force, at this time, the coil 33 is in an unoperated state, that is, the coil 33 does not generate the second magnetic force, and the installation and fixing of the appearance component 40 can be completed, no glue is required, and the installation process is simple.

When the terminal device 100 is a perfect terminal product, the first magnetic force generated by the magnet 31 in the magnetic assembly 30 attracts the magnetic body 43 in the appearance assembly 40, thereby fixing the appearance assembly 40, and the coil 33 is in the inactive state, i.e. the coil 33 does not generate the second magnetic force.

When the appearance assembly 40 needs to be disassembled, the processor 90 controls the current flowing through the coil 33 by the circuit board 60, the coil 33 is in an operating state, and generates a second magnetic force which is repulsive to the first magnetic force, so that the adsorption force of the first magnetic force to the magnetic body 43 is reduced or eliminated, and the appearance assembly 40 is not damaged. Specifically, referring to fig. 7, magnet 31 has an inherent first magnetic force, wherein the side of magnet 31 facing away from appearance element 40 is N-pole and the side facing toward appearance element 40 is S-pole; the current is applied to the coil 33, so that a second magnetic force is generated in the coil 33, and the coil 33 faces the N pole on one side of the appearance component 40, and faces the S pole on the other side of the appearance component 40. That is, the directions of the first magnetic force and the second magnetic force are just opposite, so that the adsorption force of the first magnetic force to the magnetic body 43 is reduced or counteracted. After the exterior assembly 40 is disassembled, the current flowing through the coil 33 is disconnected.

In the process of fixing the appearance component 40 on the decoration 20, the assembly is convenient, and a complicated dispensing process is not needed. When the exterior component 40 is fixed to the decorative piece 20, the exterior component 40 is attracted by the first magnetic force of the magnet 31 without providing additional energy for fixing the exterior component 40. When the appearance component 40 needs to be disassembled, the disassembly can be completed only by generating a second magnetic force which is repulsive to the first magnetic force through the coil 33, and the disassembly process is simple and convenient; meanwhile, the disassembly process is nondestructive disassembly, namely, each element of the disassembled terminal equipment 100 is intact, so that the damage of the disassembled element caused by glue adhesion in the related technology is avoided; and the energy consumption in the disassembly process is low.

The above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present application.
