[0043] Referring to Figure 1 An embodiment of the present application provides a microphone sealing mechanism, comprising a support 1 and a first sealing member 2. The microphone sealing mechanism is arranged in a mounting shell 3, the mounting shell 3 has a bottom wall 31 and a side wall 32, and the bottom wall 31 and the side wall 32 can cooperate to enclose a space for accommodating components such as the support 1 and the first sealing member 2 of the microphone sealing mechanism.

[0044] The support 1 is arranged on the bottom wall 31, and the first sealing member 2 is in abutting cooperation with the support 1. A containing cavity is enclosed between the first sealing member 2 and the side wall 32, and the microphone assembly 7 can be sealed in the containing cavity.

[0045] Specifically, referring to Figures 1-3 In the embodiment of the present application, the bottom wall 31 is a circular face or an annular face, and the side wall 32 is an annular face. The support 1 and the first sealing member 2 are both provided in plurality, the plurality of supports 1 are spaced around the circumference of the bottom wall 31, and the plurality of first sealing members 2 are arranged one by one on the plurality of supports 1. The FPC soft board 8 is an arc-shaped plate, and the axis of the FPC soft board 8 coincides with the axis of the bottom wall 31. Each microphone assembly 7 on the FPC soft board 8 is sealed in the corresponding containing cavity.

[0046] In summary, when the microphone sealing mechanism of the present application is used, the FPC soft board 8 with the microphone assembly 7 can be installed on the side wall 32, and then the first sealing member 2 is placed on the support 1. The abutting cooperation between the first sealing member 2 and the FPC soft board 8 is realized, so that the microphone assembly 7 can be sealed in the containing cavity.

[0047] The above-mentioned microphone sealing mechanism realizes the abutting cooperation between the first sealing member 2 and the support 1, so that the first sealing member 2 can move towards the side wall 32 when assembled on the support 1, to give a pressing force to the FPC soft board 8 on the side wall 32, so that the FPC soft board 8 is in close contact with the first sealing member 2, and then the microphone assembly 7 on the FPC soft board 8 can be sealed in the containing cavity. The effective sealing of the microphone assembly 7 is realized in the case that the overall structure and assembly process are relatively simple, and the preparation cost is relatively low.

[0048] Referring to Figures 2-4In one of the embodiments, the microphone sealing mechanism further comprises a second sealing member 4, which is arranged on the side wall 32, and a receiving cavity is enclosed between the first sealing member 2 and the second sealing member 4, and the FPC soft board 8 can be clamped between the first sealing member 2 and the second sealing member 4, thereby improving the sealing effect on the microphone assembly 7 on the FPC soft board 8.

[0049] More specifically, the first sealing member 2 is provided with a receiving groove 23 on the side surface thereof facing the side wall 32. That is, in the embodiment of the present application, the second sealing member 4 is arranged on the side wall 32, the first sealing member 2 is provided with the receiving groove 23 on the side surface thereof facing the second sealing member 4, the receiving cavity is enclosed by the receiving groove 23 and the side surface of the second sealing member 4 facing the first sealing member 2, and the microphone assembly 7 on the FPC soft board 8 is sealed by being arranged in the receiving groove 23.

[0050] Referring to Figure 3 , Figures 5-6 In one of the embodiments, the support 1 has a first inclined surface 11 facing the side wall 32, and the first sealing member 2 has a second inclined surface 21 abutting against the first inclined surface 11. Through the cooperation between the second inclined surface 21 of the first sealing member 2 and the first inclined surface 11 of the support 1, the first sealing member 2 can be moved towards the side wall 32 and the second sealing member 4 when assembled on the support 1, so as to provide a pressing force to the FPC soft board 8 between the first sealing member 2 and the second sealing member 4, and the FPC soft board 8 can be clamped by the first sealing member 2 and the second sealing member 4.

[0051] Specifically, referring to Figure 3 and Figure 7 , the first sealing member 2 has a first sealing surface 24 facing the second sealing member 4, and the second sealing member 4 has a second sealing surface facing the first sealing member 2, which is parallel to the first sealing surface 24 to match the shape of the FPC soft board 8.

[0052] More specifically, the first sealing member 2 has the first sealing surface 24 facing the second sealing member 4, and the receiving groove 23 is arranged on the first sealing surface 24. This structure can not only seal the microphone assembly 7 in the receiving groove 23 of the first sealing member 2, but also not affect the assembly of the first sealing member 2 when the microphone assembly 7 is arranged in the receiving groove 23.

[0053] That is, the arrangement of the receiving groove 23 can prevent the microphone assembly 7 from touching the side surface of the first sealing member 2 facing the bottom wall 31 when arranged in the receiving groove 23, thereby avoiding affecting the assembly of the first sealing member 2.

[0054] In summary, the microphone sealing mechanism of the present application can be assembled with the FPC soft plate 8, and the FPC soft plate 8 can be first attached to one side of the second sealing member 4, then the first sealing member 2 is placed on the bracket 1, and the first sealing member 2 is guided by the first inclined surface 11 to move towards the second sealing member 4 until the other side of the FPC soft plate 8 is abutted, so as to achieve the fastening and clamping of the FPC soft plate 8. The above-mentioned microphone sealing mechanism can move the first sealing member 2 towards the second sealing member 4 when assembled on the bracket 1 through the cooperation between the second inclined surface 21 of the first sealing member 2 and the first inclined surface 11 of the bracket 1, so as to provide a pressing force to the FPC soft plate 8 between the first sealing member 2 and the second sealing member 4, so that the FPC soft plate 8 can be fastened and clamped by the first sealing member 2 and the second sealing member 4, and the microphone assembly 7 on the FPC soft plate 8 can be sealed inside the accommodating cavity. The overall structure and assembly process are relatively simple, and the preparation cost is relatively low.

[0055] Referring to Figures 2-3 In one embodiment, the first sealing member 2 is connected to the bracket 1 by the fixing member 13 to ensure the stability of the first sealing member 2 on the bracket 1. Since the first sealing member 2 can be fixed to the bracket 1 by only the fixing member 13 after being assembled in place, the assembly structure and process of the present application are simple, and the preparation cost is saved.

[0056] Specifically, the fixing member 13 is arranged on the bracket 1 and the first sealing member 2 and detachably connected to the bracket 1 and the first sealing member 2. The detachable connection enables the components to be quickly detached and installed when maintenance or replacement is required, reduces maintenance time and cost, and makes the assembly simpler and more intuitive, which is convenient for the assembly personnel to operate.

[0057] More specifically, the fixing member 13 is a screw, and the fixing member 13 is arranged on and screwed to the bracket 1 and the first sealing member 2 to achieve the connection between the bracket 1 and the first sealing member 2 while enabling the bracket 1 and the first sealing member 2 to be detachable. In addition, since the first sealing member 2 can be fixed to the bracket 1 by only one screw after being assembled in place, the assembly structure and process of the present application are simple, and the preparation cost is saved.

[0058] Referring to Figure 3 and Figure 6 In one embodiment, the bracket 1 further has a first positioning surface 12 intersecting the first inclined surface 11, and the first sealing member 2 has a second positioning surface 22 intersecting the second inclined surface 21, and the second positioning surface 22 abuts against the first positioning surface 12. The second positioning surface 22 and the first positioning surface 12 can ensure the accurate position of the first sealing member 2 on the bracket 1 and prevent the first sealing member 2 from shifting or shaking during the fixing process of the fixing member 13, so as to fix the first sealing member 2 and the bracket 1 by the fixing member 13.

[0059] Specifically, the first sealing member 2 is sleeved on the support 1 to increase the contact area between the first sealing member 2 and the support 1 and improve the stability between the first sealing member 2 and the support 1. When the first sealing member 2 is assembled, the second inclined surface 21 gradually contacts and slides on the first inclined surface 11 until the second positioning surface 22 abuts against the first positioning surface 12.

[0060] Referring to Figures 6-8 In one embodiment, the first sealing member 2 has two reinforcing walls 25 on opposite sides of the second inclined surface 21, and the support 1 has two opposite side portions 14, each of which has the first inclined surface 11 formed thereon, and the two reinforcing walls 25 are respectively attached to the two side portions 14. The above structure can realize the assembly of the first sealing member 2 on the support 1, and the reinforcing walls 25 and the side portions 14 can not only guide the first sealing member 2, but also increase the contact area between the first sealing member 2 and the support 1 and improve the stability between the first sealing member 2 and the support 1.

[0061] To further improve the guiding effect of the first sealing member 2 and ensure the stability of the first sealing member 2 when moving on the first inclined surface 11, in one embodiment, the microphone sealing mechanism further comprises a first positioning member 5 and a second positioning member 6 arranged on the side wall 32, and the first positioning member 5 and the second positioning member 6 are respectively arranged on two opposite sides of the first sealing member 2.

[0062] When the first sealing member 2 is assembled, the two opposite sides of the first sealing member 2 respectively contact the first positioning member 5 and the second positioning member 6, and the contact area between the first positioning member 5 and the first sealing member 2 gradually increases as the distance between the first sealing member 2 and the bottom wall 31 decreases, and the contact area between the second positioning member 6 and the first sealing member 2 gradually increases as the distance between the first sealing member 2 and the bottom wall 31 decreases.

[0063] Referring to Figure 2 In one embodiment, the second sealing member 4 is a foam which is adhered to the side wall 32. The foam can realize the adhesion, sealing and buffering between the mounting shell 3 and the FPC soft board 8. More specifically, the first sealing member 2 comprises a foam, a mesh cloth and a double-sided adhesive tape, the foam is attached to the side wall 32, the mesh cloth is arranged between the foam and the double-sided adhesive tape, and the side of the FPC soft board 8 away from the microphone assembly 7 is attached to the double-sided adhesive tape.

[0064] The above structure can effectively prevent gas, liquid or other pollutants from entering the gap between the FPC soft board 8 and the shell through the good sealing performance of the foam glue. And through the buffering and shock absorbing effect of the foam glue, the FPC soft board 8 is protected from external force impact during use. The mesh structure of the mesh cloth provides a larger contact area, enhances the adhesion of the glue, ensures the firm adhesion between the sealing foam and the double-sided adhesive, and further ensures the firm adhesion of the sealing foam between the mounting shell 3 and the FPC soft board 8.

[0065] Referring to Figures 5-6 According to another aspect of the present application, an electronic device is provided, which comprises a mounting shell 3, a microphone assembly 7 and the microphone sealing mechanism of any one of the above embodiments, the microphone assembly 7 being arranged in the microphone sealing mechanism to achieve sealing of the microphone assembly 7 by the microphone sealing mechanism.

The mounting shell 3 has a bottom wall 31 and a side wall 32, which can cooperate to enclose a space for accommodating components such as the bracket 1 and the first sealing member 2 of the microphone sealing mechanism.

[0067] The bracket 1 is arranged on the bottom wall 31, and the first sealing member 2 is in abutting contact with the bracket 1. A containing cavity is enclosed between the first sealing member 2 and the side wall 32, and the microphone assembly 7 can be sealed in the containing cavity.

[0068] Referring to Figures 1-3 In one embodiment, the microphone sealing mechanism is multiple groups, the number of microphone assemblies 7 corresponds to the microphone sealing mechanism, and each microphone assembly 7 is arranged on the FPC soft board 8, and the FPC soft board 8 is arranged on the side wall 32 of the mounting shell 3.

[0069] Specifically, the bottom wall 31 of the mounting shell 3 is a circular face or an annular face, and the side wall 32 is an annular face. The bracket 1 and the first sealing member 2 are both provided with multiple, the multiple brackets 1 are spaced around the circumference of the bottom wall 31, and the multiple first sealing members 2 are arranged one by one on the multiple brackets 1. The FPC soft board 8 is an arc-shaped board, and the axis of the FPC soft board 8 coincides with the axis of the bottom wall 31, and each microphone assembly 7 on the FPC soft board 8 is sealed in the corresponding containing cavity.

[0070] Referring to Figure 5 The mounting shell 3 is provided with a sound hole 9 corresponding to each microphone sealing mechanism, so that the sound emitted by the microphone assembly 7 located in the microphone sealing mechanism can be smoothly transmitted out.

[0071] In summary, the electronic device, through the abutting and pressing cooperation between the first sealing member 2 and the support 1 of the microphone sealing mechanism, the first sealing member 2 can move to the direction close to the side wall 32 when assembled on the support 1, so as to give a pressing force to the FPC soft board 8 located on the side wall 32, so that the FPC soft board 8 is in close contact with the first sealing member 2, and then the microphone assembly 7 on the FPC soft board 8 can be sealed in the accommodating cavity, and the effective sealing of the microphone assembly 7 is realized under the conditions that the overall structure and the assembly process are relatively simple, and the preparation cost is relatively low.
