[0024] The following is the content of the first aspect of this utility model:
[0025] Please refer to Figures 1 to 4 In this embodiment, the present invention provides an earphone sound guiding structure, which includes a housing 1, an FPC component 2, a microphone 3 and a bracket 4; a cavity 11 is formed inside the housing 1, and a sound guiding channel 12 communicating with the outside is provided on the housing 1; a mounting groove 13 communicating with the sound guiding channel 12 is provided inside the housing 1.
[0026] Among them, the housing 1 is part of the cavity shell of the earphone and is used to house the components in the earphone. The FPC part 2 is the load-bearing connector of the components in the earphone. The bracket 4 is used to help fix the components in the housing 1 and can adjust the output sound effect in the housing 1 to a certain extent. The sound guide channel 12 is the channel for the microphone 3 to collect external sound from the housing 1.
[0027] Specifically, a limiting groove 14 is formed in the mounting groove 13; a sound guide 22 is provided on the FPC component 2; a limiting member 24 is formed on the sound guide 22; the sound guide 22 is installed in the mounting groove 13, the limiting member 24 is disposed in the limiting groove 14, and the limiting member 24 abuts against the side wall of the limiting groove 14; the microphone 3 is disposed on the sound guide 22 and located in the mounting groove 13; the bracket 4 is disposed in the cavity 11 and abuts against the limiting member 24.
[0028] The limiting groove 14 is a structure within the mounting groove 13 used to assist in constraining the degrees of freedom of the sound guide 22, and the limiting member 24 is a structure provided on the sound guide 22 to cooperate with the limiting groove 14 to constrain the degrees of freedom of the sound guide 22. The sound guide 22 is a carrier part on the FPC component 2 used for electrically connecting the microphone 3.
[0029] After the microphone 3 is installed onto the sound guide 22 on the FPC component 2, the sound guide 22 is installed into the mounting groove 13 inside the housing 1. The sound guide 22 covers the sound guide channel 12 communicating with the mounting groove 13. The limiting member 24 on the sound guide 22 is disposed in the limiting groove 14 inside the mounting groove 13. Then, the bracket 4 is installed into the cavity 11, and the bracket 4 abuts against the limiting member 24. Under the tension of the FPC component 2, the FPC component 2 pushes the limiting member 24 on the sound guide 22 to abut against the side wall of the limiting groove 14. The side wall of the limiting groove 14 applies a first force to the limiting member 24. At the same time, the bracket 4 abuts against the limiting member 24 and applies a second force to the limiting member 24. Under the combined action of the first force and the second force, the limiting member 24 has a tendency to move towards pressing against the mounting groove 13, thereby enabling the sound guide 22 to be stably installed in the mounting groove 13 and cover the sound guide channel 12, so that the microphone 3 on the sound guide 22 can be flat against the cavity 11 of the housing 1, which can effectively prevent the FPC part 2 from tilting up and thus affecting the sound reception effect of the microphone 3.
[0030] It is understandable that by setting mutually cooperating limiting grooves 14 and limiting members 24 on the mounting groove 13 and FPC component 2 respectively, and using the support 4 to push against the limiting member 24, the sound guide 22 can be more firmly pressed into the mounting groove 13 with a relatively simple structure, thereby making the microphone 3 flat inside the housing 1 and sealing the sound guide channel 12. At the same time, the overall structure is relatively simple, which is conducive to the assembly of the internal components of the housing 1, so as to improve the convenience and efficiency of assembly.
[0031] Furthermore, in one embodiment, please refer to Figure 2 A guide portion 15 is formed on one side of the mounting groove 13, and limiting grooves 14 are provided on both sides of the mounting groove 13. The guide portion 15 is used to assist in the installation of the sound guide portion 22 so that the FPC part 2 generates the required tension.
[0032] Specifically, the guide portion 15 can be an arc-shaped guide block or a guide arc surface, which can be selected according to the actual design requirements. During the process of installing the sound guide portion 22 into the mounting groove 13, the sound guide portion 22 can be installed along the arc of the guide portion 15, thereby creating a corresponding arc on the FPC part 2 at the position of the guide portion 15, thereby generating the required tension on the FPC part 2, thereby pushing the limiting member 24 on the sound guide portion 22 to abut against the side wall of the limiting groove 14.
[0033] Please refer to Figure 3 The FPC component 2 includes a main body 21, a sound guide 22, and an electrical connection 23. The sound guide 22 is located at one end of the main body 21, and the electrical connection 23 is located 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 the connection structure for power input to 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, with symmetrical grooves formed at one end of the main body 21, and the sound guide 22 may be disposed in the aforementioned grooves. It is understood that by setting the main body 21 into a symmetrical structure and forming grooves at one end of the main body 21 for accommodating the sound guide 22, the ease of installation of the FPC component 2 and the sound guide 22 can be improved.
[0035] Please refer to Figure 4 The bracket 4 has a clearance groove 41, within which a stop member 42 is formed for abutting against the limiting member 24. The clearance groove 41 provides space for the microphone 3 mounted on the sound guide 22 and also assists in the installation of the bracket 4 to some extent. The stop member 42 abuts against the limiting member 24 to restrict its degree of freedom.
[0036] Specifically, after the bracket 4 is installed into the cavity 11, the mounting groove 13 in the housing 1 is located in the clearance groove 41, the abutment 42 is located in the limiting groove 14 and abuts against the limiting member 24 to apply pressure to the limiting member 24, thereby restricting the degree of 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 processing difficulty of the bracket 4, while providing relatively more clearance space for the bracket 4.
[0038] It is understandable that by opening the clearance groove 41 on the bracket 4, the microphone 3 can be effectively avoided, thereby optimizing the stacking structure of the components inside the housing 1 and reducing the size of the headphones to a certain extent. At the same time, by setting the abutment 42 in the clearance groove 41, it is possible to visually observe whether the abutment 42 is set in the limiting groove 14 when installing the bracket 4, thereby improving the efficiency and convenience of installing the bracket 4.
[0039] Furthermore, the number of limiting grooves 14 and limiting members 24 affects the stability of the constraint on the sound guide 22. In a preferred embodiment, there are two limiting grooves 14 and two limiting members 24. It is easy to understand that by setting the number of limiting grooves 14 and two limiting members 24, the production cost can be reduced while ensuring the stability of the constraint force on the FPC part 2 under the interaction of the limiting grooves 14 and the limiting members 24, and ensuring the efficiency of assembly between the limiting grooves 14 and the limiting members 24.
[0040] Furthermore, 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 22 and the mounting groove 13. Specifically, the tuning mesh is adhered to the mounting groove 13. It is understood that by providing the tuning mesh, waterproofing and dustproofing 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 [link / reference]. 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 part 22 of the FPC part 2 is glued into the mounting groove 13, the main body part 21 of the FPC part 2 is glued into the first groove 16 of the housing 1, and then the bracket 4 is installed into the first groove 16 of the housing 1 so that the abutment 42 abuts against the limiting member 24 located in the limiting groove 14. Finally, the bracket 4 is fixed into the second groove 17 by applying glue.
[0043] For further details, please refer to... Figures 2 to 4 In a preferred embodiment, a positioning post 18 is provided inside 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 readily understood that the cooperation between the positioning post 18 and the first positioning hole 25 enables rapid positioning and installation between the housing 1 and the FPC component 2, thereby improving the efficiency and convenience of installing the FPC component 2; similarly, the cooperation between the positioning post 18 and the second positioning hole 43 enables rapid positioning and installation between the housing 1 and the bracket 4, thereby improving the efficiency and convenience of installing the bracket 4.
[0044] In summary, this utility model, by setting mutually cooperating limiting grooves 14 and limiting members 24 on the mounting groove 13 and FPC component 2 respectively, and then using the supporting bracket 4 to abut the limiting member 24, can achieve the sound guide part 22 being pressed into the mounting groove 13 with a relatively simple structure, thereby realizing that the microphone 3 is flatly attached to the inside of the housing 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 the internal components of the housing 1, thereby improving the convenience and efficiency of assembly.
[0045] The second aspect of this utility model also provides an earphone, which includes the earphone sound guiding structure in the foregoing embodiment. The overall structure of the earphone sound guiding structure is relatively simple. While improving the convenience and efficiency of assembly, it allows the microphone 3 on the FPC part 2 to be flat against the shell 1 and serves to seal the sound guiding channel 12.
[0046] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the contents of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
