[0038] As shown in the figure, Figure 7 The conductive part 4 includes a first conductive wire 41, a second conductive wire 42 and a connecting conductive wire 43. Among them, the first conductive wire 41 is arranged on the surface of the mounting bracket 3 close to the shell 1, used for contact connection with the metal decoration 2; the second conductive wire 42 is arranged on the surface of the mounting bracket 3 away from the shell 1, used for electrical connection with the flexible circuit board 5; the connecting conductive wire 43 is arranged on the aperture surface of the first connecting through hole 35 and the two ends are respectively electrically connected with the first conductive wire 41 and the second conductive wire 42, so that the static electricity generated by the metal decoration 2 can be conducted to the flexible circuit board 5 through the conductive part 4, and the flexible circuit board 5 is conducted to the grounding point of the main circuit board, thereby being introduced into the ground, avoiding damage to the electronic device caused by static electricity.

[0039] For example, the conductive part 4 is formed on both sides of the mounting bracket 3 and in the first connecting through hole 35 by using laser direct structuring (LDS) technology. That is, the laser direct structuring (LDS) technology is used to make metal wiring on both sides of the mounting bracket 3 and in the first connecting through hole 35, so as to form the first conductive wire 41, the second conductive wire 42 on both sides of the mounting bracket 3 and the connecting conductive wire 43 in the first connecting through hole 35.

[0040] The LDS process is to control the movement of laser by computer according to the track of conductive pattern, project laser onto the mounting bracket 3, and directly form metal wires on the mounting bracket 3 by using laser technology. The conductive part 4 is formed on both sides of the mounting bracket 3 and in the first connecting through hole 35 by using LDS process, for example, including the following steps:

[0041] The mounting bracket 3 is formed by injection molding, in which liquid material is injected into a mold under certain temperature and pressure on an injection molding machine. The material of the mounting bracket 3 is, for example, thermoplastic plastic. The mounting bracket 3 is formed with a circuit by laser engraving. The circuit, such as copper, nickel, etc., is electroplated on the circuit surface to form the conductive part 4 with a thickness of 5-8 microns. Finally, the mounting bracket 3 with the conductive part 4 formed on the surface is assembled in the housing 1.

[0042] The electronic device provided in the embodiments of the present application forms the conductive part on the mounting bracket by the LDS process, so that the conductive part is more stable in connection with the mounting bracket and is not easy to fall off, and the internal space of the electronic device is not occupied, which is beneficial to the miniaturization of the electronic device.

[0043] As shown in Figure 4 and Figure 5 , the mounting bracket 3 includes a laser forming area 31 and two fixing areas 32. The first connecting through hole 35 is arranged in the laser forming area 31, and the two fixing areas 32 are arranged on both sides of the laser forming area 31. The conductive part 4 is formed on the laser forming area 31 by the LDS process. The two fixing areas 32 are arranged on the side of the mounting bracket 3 close to the flexible circuit board 5, and the two fixing areas 32 are used to fix the flexible circuit board 5.

[0044] In the embodiment, the two ends of the mounting bracket 3 are respectively provided with annular protrusions 33, and the annular protrusions 33 surround to form the fixing areas 32. The annular protrusions 33 are provided with openings communicating with the laser forming area 31, as shown in Figure 4 . The fixing areas 32 formed by the annular protrusions 33 can better fix the two ends of the flexible circuit board 5, and the shape thereof is adapted to the structure of the two ends of the flexible circuit board 5. The openings of the annular protrusions 33 enable the flexible circuit board 5 to be connected on the mounting bracket 3 as a whole, so as to maintain the flatness and stability of the mounting. The two ends of the flexible circuit board 5 can be pasted in the fixing areas 32 by using glue or pressure-sensitive adhesive, and the part of the flexible circuit board 5 corresponding to the laser forming area 31 can be fixedly connected and electrically connected with the conductive part 4 formed on the laser forming area 31 by laser welding or conductive adhesive, so as to realize the assembly of the flexible circuit board 5 and the mounting bracket 3.

[0045] In the embodiment, the flexible circuit board 5 includes a first flexible part 51 and a second flexible part 52 connected to form a T shape. The first flexible part 51 is respectively connected with a microphone 53 and an electronic component 54 at two ends thereof. The second flexible part 52 is provided with a copper exposure area 55 close to one end of the first flexible part 51, as shown in Figure 3As shown in the figure. Among them, the first flexible part 51 forms a rectangular structure at both ends, and a microphone 53 and electronic components 54 are arranged on it respectively, which can realize specific electronic functions, such as collecting sound and processing in devices such as phones, watches, etc. Voice command recognition, call, etc. The rectangular structure formed at both ends of the first flexible part 51 is consistent with the shape of the fixed area 32 formed by the annular protrusion 33, so as to ensure that the first flexible part 51 provided with the microphone 53 and the electronic components 54 can be installed flat on the mounting bracket 3. Alternatively, the first flexible part 51 is pasted in the fixed area 32 by glue or pressure-sensitive adhesive. The second flexible part 52 is provided with a copper exposed area 55 near one end of the first flexible part 51, and the copper exposed area 55 is connected in conduction with the second conductive wire 42 of the conductive part 4 through conductive glue or welding, so as to realize the electrical connection between the conductive part 4 and the flexible circuit board 5. The other end of the second flexible part 52 extends into the cavity 11 from below the mounting bracket 3 and is electrically connected with the main circuit board, so as to realize the grounding of the metal decorative part and improve the safety performance of the electronic device.

[0046] As shown in the figure, Figure 5 The mounting bracket 3 also includes two pickup holes 34 located on the side of the mounting bracket 3 close to the shell 1, and the two pickup holes 34 are arranged correspondingly with the two fixed areas 32, and a second connecting through hole 36 is arranged between the pickup hole 34 and the fixed area 32.

Preferably, the length of the elastic conductive column 6 is slightly longer than the depth of the second mounting through hole 13, so that after the mounting bracket 3, the metal decorative part 2 and the shell 1 are fixedly connected, the two ends of the elastic conductive column 6 can be pressed to be compressed, so as to ensure that the elastic conductive column 6 always maintains contact and electrical connection with the metal decorative part 2 and the conductive part 4. The material of the elastic conductive column 6 is conductive silicone or conductive rubber. The conductive silicone or conductive rubber uniformly distributes conductive particles such as silver-coated glass, silver-coated aluminum and silver in silicone or rubber, and makes the conductive particles contact through pressure to achieve good conductivity.

[0049] Further, the housing 1 is provided with a plurality of limiting bosses 14 arranged in the height direction and two limiting plates 15 arranged in the lateral direction, and the plurality of limiting bosses 14 and the two limiting plates 15 form an installation area 16, as shown in Figure 6 The first installation through hole 12 and the second installation through hole 13 are arranged in the installation area 16.

In addition, the mounting bracket 3 can be pasted with glue in the installation area 16. The structure of the housing 1 and the structure of the mounting bracket 3 can ensure the relative position relationship between the structures and the stability of the connection when the mounting bracket 3 is assembled with the housing 1.

[0050] In order to further improve the safety performance of the electronic device, the housing 1 and the mounting bracket 3 can be made of insulating materials such as plastic and rubber.
