[0024] The following is the content of the first aspect of the present invention:

[0025] Please refer to Figures 1 to 4 In this embodiment, the present invention provides an earphone sound guide structure, which includes a shell 1, an FPC component 2, a microphone 3 and a bracket 4; a cavity 11 is formed in the shell 1, and a sound guide channel 12 connecting the cavity 11 with the outside is provided on the shell 1; a mounting groove 13 connecting the sound guide channel 12 is provided in the shell 1.

[0026] Among them, the shell 1 is a part of the cavity shell of the earphone, which is used to accommodate the components in the earphone. The FPC component 2 is a load-bearing connector for the components in the earphone. The bracket 4 is used to assist in fixing the components in the shell 1 and can adjust the sound output effect in the shell 1 to a certain extent. The sound guide channel 12 is a channel for the microphone 3 to collect external sound of the shell 1.

[0027] Specifically, a limiting groove 14 is formed in the mounting groove 13; a sound guide portion 22 is provided on the FPC component 2; a limiting member 24 is formed on the sound guide portion 22; the sound guide portion 22 is installed in the mounting groove 13, the limiting member 24 is arranged in the limiting groove 14, and the limiting member 24 abuts against the side wall of the limiting groove 14, the microphone 3 is arranged on the sound guide portion 22, and is located in the mounting groove 13; the bracket 4 is arranged in the cavity 11, and abuts against the limiting member 24.

[0028] The limiting groove 14 is a structure in the mounting groove 13 for assisting in restricting the freedom of the sound guide 22, and the limiting member 24 is a structure provided on the sound guide 22 for cooperating with the limiting groove 14 to restrict the freedom of the sound guide 22. The sound guide 22 is a bearing part on the FPC part 2 for electrically connecting the microphone 3.

[0029] After the microphone 3 is mounted on the sound guide part 22 on the FPC component 2, the sound guide part 22 is mounted in the mounting groove 13 in the housing 1, the sound guide part 22 covers the sound guide channel 12 connected to the mounting groove 13, the stopper 24 on the sound guide part 22 is set in the stopper 14 in the mounting groove 13, and then the bracket 4 is mounted in the cavity 11, and the bracket 4 abuts against the stopper 24. Under the tension of the FPC component 2, the FPC component 2 pushes the stopper 24 on the sound guide part 22 to abut against the side wall of the stopper 14, and the side wall of the stopper 14 applies a first force to the stopper 24, and at the same time, the bracket 4 abuts against the stopper 24 and applies a second force to the stopper 24. Under the combined action of the first force and the second force, the limiting member 24 has a tendency to move toward being pressed into the mounting groove 13, so that the sound guide portion 22 can be stably installed in the mounting groove 13 and cover the sound guide channel 12, so that the microphone 3 on the sound guide portion 22 can be flatly attached to the cavity 11 of the shell 1, which can effectively prevent the FPC component 2 from warping up, thereby affecting the sound reception effect of the microphone 3.

[0030] It can be understood that by respectively providing a limit groove 14 and a limit member 24 that can cooperate with each other on the installation groove 13 and the FPC component 2, and then utilizing the supporting effect of the bracket 4 on the limit member 24, the sound guide part 22 can be pressed more firmly into the installation groove 13 with a relatively simple structure, thereby achieving the microphone 3 being flat against the inside of the shell 1 and playing the role of sealing the sound guide channel 12. At the same time, the overall structure is relatively simple, which is conducive to the assembly of components inside the shell 1, so as to improve the convenience and efficiency of assembly.

[0031] Further, in one embodiment, please refer to Figure 2 A guide portion 15 is formed on one side of the installation slot 13, and the limiting slots 14 are arranged on both sides of the installation slot 13. The guide portion 15 is used to assist the installation of the sound guide portion 22 so that the FPC component 2 generates the required tension.

[0032] Specifically, the guide portion 15 can be a guide block with an arc, or a guide arc surface, which can be selected according to the actual design requirements. In the process of installing the sound guide portion 22 into the installation groove 13, the sound guide portion 22 can be installed along the arc of the guide portion 15, so that the FPC component 2 can generate a corresponding arc at the position where the guide portion 15 is located, and the FPC component 2 can generate the required tension, thereby pushing the limiter 24 on the sound guide portion 22 to abut against the side wall of the limiter groove 14.

[0033] Please refer to Figure 3The FPC component 2 includes a main body 21, a sound guide 22 and an electrical connection 23; the sound guide 22 is arranged at one end of the main body 21, and the electrical connection 23 is arranged at the other end of the main body 21. The main body 21 is the main part of the FPC component 2 structure, and the electrical connection 23 is a connection structure for the power input of the FPC component 2, which can provide power to the components connected to the FPC component 2.

[0034] In a preferred embodiment, the main body 21 may be symmetrical, and a symmetrical groove is provided on one end of the main body 21, and the sound guide 22 may be disposed in the aforementioned groove. It is understandable that by providing the main body 21 with a symmetrical structure and providing a groove for accommodating the sound guide 22 on one end of the main body 21, the convenience of installing the FPC component 2 and the sound guide 22 can be improved.

[0035] Please refer to Figure 4 The bracket 4 is provided with an avoidance groove 41, and a resisting member 42 for resisting the limiter 24 is formed in the avoidance groove 41. The avoidance groove 41 can be set to avoid the accommodating space of the microphone 3 on the sound guide 22, and can assist the installation of the bracket 4 to a certain extent. The resisting member 42 is used to resist the limiter 24 to restrict the freedom of the limiter 24.

[0036] Specifically, after the bracket 4 is installed in the cavity 11, the installation groove 13 in the shell 1 is located in the avoidance groove 41, and the abutting member 42 is located in the limiting groove 14 and abuts against the limiting member 24 to apply pressure to the limiting member 24, thereby constraining the freedom of the limiting member 24.

[0037] In a preferred embodiment, the bracket 4 is a U-shaped bracket. It is easy to understand that the U-shaped bracket can relatively reduce the difficulty of processing the bracket 4 and provide relatively more avoidance space for the bracket 4.

[0038] It can be understood that by opening the avoidance groove 41 on the bracket 4, the microphone 3 can be effectively avoided to optimize the stacking structure of the components in the shell 1, thereby reducing the volume of the earphone to a certain extent. At the same time, the push-up member 42 is arranged in the avoidance groove 41. When installing the bracket 4, it can be intuitively observed whether the push-up member 42 is arranged in the limit groove 14, thereby improving the efficiency and convenience of the installation of the bracket 4.

[0039] Furthermore, the number of the limiting grooves 14 and the limiting members 24 will affect the stability of the constraint on the sound guide 22. In a preferred embodiment, the number of the limiting grooves 14 and the limiting members 24 are both two. It is easy to understand that setting the number of the limiting grooves 14 and the limiting members 24 to two can ensure the stability of the constraint force on the FPC part 2 under the interaction between the limiting grooves 14 and the limiting members 24, reduce the production cost, and ensure the assembly efficiency between the limiting grooves 14 and the limiting members 24.

[0040] Furthermore, in order to improve the quality of the sound collected by the microphone 3 through the sound guide channel 12, in a preferred embodiment, a tuning mesh is provided between the sound guide portion 22 and the mounting groove 13. Specifically, the tuning mesh is bonded to the mounting groove 13. It can be understood that by providing the tuning mesh, waterproof and dustproof can be effectively achieved, and at the same time, the sound collected by the microphone 3 through the sound guide channel 12 can be effectively adjusted.

[0041] For further information, please refer to Figure 2 In one embodiment, a first groove 16 for mounting the FPC component 2 is formed in the housing 1 , and a second groove 17 for mounting the bracket 4 is formed in the housing 1 .

[0042] Specifically, after the sound guide portion 22 of the FPC component 2 is bonded into the installation groove 13, the main body 21 of the FPC component 2 is bonded into the first groove 16 of the shell 1, and then the bracket 4 is installed in the first groove 16 of the shell 1, so that the abutting member 42 abuts against the limiting member 24 located in the limiting groove 14, and finally the bracket 4 is fixed in the second groove 17 by gluing.

[0043] For further information, please refer to Figures 2 to 4 In a preferred embodiment, a positioning column 18 is provided in the housing 1, a first positioning hole 25 is provided on the FPC component 2, and a second positioning hole 43 is provided on the bracket 4. It is easy to understand that through the cooperation between the positioning column 18 and the first positioning hole 25, the housing 1 and the FPC component 2 can be quickly positioned and installed, thereby improving the efficiency and convenience of installing the FPC component 2; through the cooperation between the positioning column 18 and the second positioning hole 43, the housing 1 and the bracket 4 can be quickly positioned and installed, thereby improving the efficiency and convenience of installing the bracket 4.

[0044] In summary, the present invention respectively arranges a limit groove 14 and a limit member 24 that can cooperate with each other on the installation groove 13 and the FPC part 2, and then utilizes the supporting effect of the bracket 4 on the limit member 24, so that the sound guide part 22 can be pressed into the installation groove 13 with a relatively simple structure, thereby realizing that the microphone 3 is flatly attached to the shell 1 and plays the role of sealing the sound guide channel 12. At the same time, the overall structure is relatively simple, which is conducive to the assembly of components inside the shell 1, so as to improve the convenience and efficiency of assembly.

[0045] The second aspect of the present invention also provides an earphone, which includes the earphone sound guide structure of the aforementioned embodiment. The overall structure of the earphone sound guide structure is relatively simple. While improving the convenience and efficiency of assembly, the microphone 3 on the FPC component 2 can be flatly attached to the shell 1 and play the role of sealing the sound guide channel 12.

[0046] The above are only partial or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
