[0035] Figure 1 and Figure 2 is a schematic diagram of the electronic device of this embodiment. The electronic device can be a 3C electronic consumer product such as earphones, watches, headphones, TWS earphones, bracelets, etc. The electronic device includes a housing 1, a metal decorative part 2, a mounting bracket 3, a conductive part 4, a flexible circuit board 5 and a main circuit board, such as Figure 1 The housing 1 is provided with a cavity 11 inside, and the cavity 11 is used to place the mounting bracket 3, the conductive part 4, the flexible circuit board 5 and the main circuit board.

[0036] like Figure 6 As shown, a first mounting through hole 12 is provided on the housing 1. The metal decorative part 2 is connected in the first mounting through hole 12, which can improve the aesthetics of the electronic device and other quality requirements, such as acoustic performance. When the electronic device is an earphone, the first mounting through hole 12 can be a sound leakage hole, and the metal decorative part 2 is a dustproof net; at this time, the first mounting through hole 12 is used to connect the cavity 11 with the external environment, facilitate the inflow and outflow of external air, balance the internal pressure of the earphone, bring better auditory effects, and improve the acoustic performance of the earphone; the metal decorative part 2 acts as a dustproof net to isolate impurities in the external environment outside the dustproof net, and prevent impurities from entering the cavity and affecting the acoustic performance of the earphone.

[0037] like Figure 2As shown, the mounting bracket 3 is disposed in the cavity 11, and the mounting bracket 3 is relatively fixedly connected to the housing 1 and the corresponding position of the metal decorative part 2. Figure 4 and Figure 5 As shown, the mounting bracket 3 is provided with a first connecting through hole 35. The conductive portion 4 is provided on both sides of the mounting bracket 3 and in the first connecting through hole 35. Figure 2 As shown, the flexible circuit board 5 is arranged on the side of the mounting bracket 3 away from the housing 1, and the flexible circuit board 5 is electrically connected to the metal decorative part 2 through the conductive part 4. The main circuit board is arranged in the cavity 11, and the main circuit board is electrically connected to the flexible circuit board 5. When the electronic device is used or tested, the static electricity generated by the metal decorative part 2 is discharged and conducted to the grounding point of the main circuit board through the conductive part 4 and the flexible circuit board 5, and then introduced into the ground, so that it will not cause damage to other electronic devices in the electronic device, thereby improving the safety of the electronic device.

[0038] like Figure 7 As shown, the conductive part 4 includes a first conductive line 41, a second conductive line 42 and a connecting conductive line 43. The first conductive line 41 is arranged on the surface of the mounting bracket 3 close to the housing 1, and is used to contact and connect with the metal decorative part 2; the second conductive line 42 is arranged on the surface of the mounting bracket 3 away from the housing 1, and is used to be electrically connected with the flexible circuit board 5; the connecting conductive line 43 is arranged on the aperture surface of the first connecting through hole 35, and the two ends are electrically connected to the first conductive line 41 and the second conductive line 42 respectively, so that the static electricity generated by the metal decorative part 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 earth to prevent static electricity from damaging the electronic equipment.

[0039] Exemplarily, 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). That is, metal wiring is made on both side surfaces of the mounting bracket 3 and in the first connecting through hole 35 by using laser direct structuring (LDS), so as to form the first conductive wire 41 and the second conductive wire 42 on both side surfaces of the mounting bracket 3 and form the connecting conductive wire 43 in the first connecting through hole 35.

[0040] The LDS process uses a computer to control the movement of the laser according to the trajectory of the conductive pattern, projects the laser onto the mounting bracket 3, and uses laser laser technology to directly plate metal wires on the mounting bracket 3. The LDS process is used to form the conductive part 4 on both side surfaces of the mounting bracket 3 and in the first connecting through hole 35, for example, including the following steps:

[0041] Injection molding: under a certain temperature and pressure, liquid material is injected into the mold on an injection molding machine to form the mounting bracket 3. The mounting bracket 3 is made of, for example, thermoplastic plastic. Laser: a laser laser process is used to form a circuit on the mounting bracket 3. Electroplating: a 5-8 micron circuit, such as copper, nickel, etc., is electroplated on the surface of the above circuit as the conductive part 4. 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 embodiment of the present application uses the LDS process to form the conductive part on the mounting bracket, so that the connection between the conductive part and the mounting bracket is more stable and not easy to fall off. At the same time, it does not need to occupy the internal space of the electronic device, which is conducive to the miniaturization of the electronic device.

[0043] like Figure 4 and Figure 5 As shown, 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. Among them, the conductive part 4 is formed in the laser forming area 31 by the LDS process. The two fixing areas 32 are arranged on one 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 this embodiment, annular protrusions 33 are respectively provided at both ends of the mounting bracket 3, and the annular protrusions 33 surround and form a fixing area 32. The annular protrusions 33 are provided with an opening communicating with the laser forming area 31, such as Figure 4 As shown. The fixing area 32 formed by the annular protrusion 33 can better fix the two ends of the flexible circuit board 5, and its shape is adapted to the two end structures of the flexible circuit board 5. The opening of the annular protrusion 33 allows the flexible circuit board 5 to be connected to the mounting bracket 3 as a whole, maintaining flatness and installation stability. The two ends of the flexible circuit board 5 can be pasted in the fixing area 32 by 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 to the conductive part 4 formed in the laser forming area 31 by laser welding or conductive adhesive bonding, thereby realizing the assembly of the flexible circuit board 5 and the mounting bracket 3.

[0045] In this embodiment, the flexible circuit board 5 includes a first flexible portion 51 and a second flexible portion 52 connected to form a T-shape, a microphone 53 and an electronic component 54 are connected to both ends of the first flexible portion 51, and a copper exposed area 55 is provided at one end of the second flexible portion 52 close to the first flexible portion 51. Figure 3As shown. Among them, the two ends of the first flexible part 51 form a rectangular structure, on which a microphone 53 and an electronic component 54 are respectively arranged, which are used to realize specific electronic functions, such as collecting and processing sounds in devices such as phones and watches for voice command recognition, calls, etc. The rectangular structure formed at the two 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 component 54 can be installed flat on the mounting bracket 3. Optionally, the two ends of the first flexible part 51 are attached to the fixed area 32 by glue or pressure-sensitive adhesive. The second flexible part 52 is provided with a copper-exposed area 55 at one end close to the first flexible part 51, and the copper-exposed area 55 is connected and conducted with the second conductive wire 42 of the conductive part 4 by conductive glue or welding, thereby realizing the electrical connection between the conductive part 4 and the flexible circuit board 5. The other end of the second flexible part 52 extends from the bottom of the mounting bracket 3 to the cavity 11, and is electrically connected to the main circuit board, thereby realizing the grounding of the metal decorative parts and improving the safety performance of the electronic equipment.

[0046] like Figure 5 As shown, the mounting bracket 3 also includes two sound pickup holes 34, which are located on one side of the mounting bracket 3 close to the housing 1, and the two sound pickup holes 34 are respectively arranged corresponding to the two fixed areas 32, and a second connecting through hole 36 is arranged between the sound pickup holes 34 and the fixed area 32. When the mounting bracket 3 is fixedly connected to the housing 1, the two sound pickup holes 34 correspond to the first mounting through hole 12, so that the two microphones 53 can pick up sound through the second connecting through hole 36, the sound pickup holes 34, and the first mounting through hole 12. Among them, the sound pickup hole 34 is a long strip structure, which can increase the sound pickup area and improve the sound pickup effect.

[0047] Furthermore, the housing 1 is provided with a second mounting through hole 13, such as Figure 6 The electronic device further comprises an elastic conductive column 6, which is mounted in the second mounting through hole 13. Figure 1 As shown. Among them, the position of the second mounting through hole 13 corresponds to the laser-formed area 31 on the mounting bracket 3, so that the two ends of the elastic conductive column 6 are respectively in contact and electrically connected with the metal decorative part 2 and the conductive part 4 (i.e., the first conductive line 41). 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 housing 1 are fixedly connected, the two can press the two ends of the elastic conductive column 6 to compress it, 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. Conductive silicone and conductive rubber are conductive particles such as glass silver-plated, aluminum silver-plated, and silver evenly distributed in silicon and rubber, and the conductive particles are brought into contact by pressure to achieve good conductive properties.

[0048] In other implementations, the metal decorative part 2 and the conductive part 4 may be connected by bonding with conductive adhesive.

[0049] Furthermore, the inner side of the housing 1 is provided with a plurality of limiting bosses 14 arranged opposite to each other in the height direction and two limiting plates 15 arranged opposite to each other in the lateral direction. The plurality of limiting bosses 14 and the two limiting plates 15 surround and form a mounting area 16. Figure 6 As shown. The first mounting through hole 12 and the second mounting through hole 13 are arranged in the mounting area 16. When the mounting bracket 3 is fixed in the mounting area 16, it can be clamped and fixed by the limiting boss 14 and the limiting plate 15 to prevent the installation position from being wrong. Furthermore, the limiting plate 15 forms a limiting groove 17, and a plug-in block 37 is convexly arranged on the outer side of the mounting bracket 3 to be inserted into the limiting groove 17. Figure 5 and Figure 6 As shown. When the mounting bracket 3 is installed in the mounting area 16, the plug block 37 is inserted into the limiting groove 17, which can further fix the mounting bracket 3 to prevent the mounting bracket 3 from falling. In addition, the mounting bracket 3 can also be glued to the mounting 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 of the electronic device can be made of insulating materials such as plastic and rubber.
