Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation to the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0044] As Figures 1 to 10 shown, an embodiment of the present invention provides a microphone structure, including: an assembly structure member 10, a sealing elastic member 20, a microphone device 30, a sealing support member 40, a connecting member 50, a threaded part 60, and a fixing part 70; the assembly structure member 10 has a through sound pickup hole 11; the two ends of the microphone device 30 are respectively a sound pickup end 31 and a mounting end 32, and the sound pickup end 31 is communicated with the sound pickup hole 11; the sealing elastic member 20 is clamped between the sound pickup end 31 and the assembly structure member 10, and is internally communicated with the sound pickup end 31 and the sound pickup hole 11 respectively; the threaded part 60 is rotatably arranged on the fixing part 70, and one end is matched with the connecting member 50; the sealing support member 40 is in abutting cooperation with the connecting member 50 and covers the outside of the mounting end 32; wherein, by rotating the threaded part 60, the connecting member 50 is driven to move towards the assembly structure member 10 to sequentially compress the sealing support member 40 and the sealing elastic member 20.

[0045] The utility model realizes the adjustment of the tight sealing degree between the sealing elastic member 20 and the sealing support member 40 with a simple structure by the cooperative work of the connecting member 50, the threaded member 60 and the fixing member 70, and also ensures that the sealing elastic member 20 and the sealing support member 40 will not become loose during long-term use, thus ensuring the reliable sealing of the microphone device 30; by arranging the sealing elastic member 20 to be in sealing cooperation with the sound pickup end 31 and the assembly structure member 10 respectively, the reliable sealing of the sound pickup end 31 is ensured; by arranging the interior of the sealing elastic member 20 to be communicated with the sound pickup end 31 and the sound pickup hole 11 respectively, the reliable sound pickup of the microphone device 30 for external sounds is ensured; by arranging the sealing support member 40 to be in abutting cooperation with the connecting member 50 and covering the outside of the installation end 32, the sealing of the installation end 32 is realized, and combined with the sealing elastic member 20, the all-round reliable sealing of the microphone device 30 is realized, so that the microphone device 30 has good airtightness, and further improves the accuracy of sound source localization and echo cancellation of the microphone device 30 in terms of structure, and can exclude the interference of external noises to the microphone device 30, ensuring the precise and reliable operation of the microphone device 30; in actual use, it is found that when using the microphone structure proposed by the utility model, the airtightness of the microphone device 30 can reach more than 20 dB, and external sounds can basically only enter from the sound pickup hole 11, so that the microphone device 30 can more clearly identify the sound source; the structure of the utility model is simple and the cost is low, which is convenient for assembly and subsequent maintenance, and is suitable for large-scale popularization and use on electronic devices.

[0046] It should be noted that: in a specific embodiment of the utility model, the assembly structure member 10 and the fixing member 70 are relatively fixedly arranged; the connecting member 50 is movably arranged on the fixing member 70, and the sealing support member 40 can directly or indirectly apply pressure to the sealing elastic member 20.

[0047] In addition, in the utility model, two technical solutions can be selected. The first technical solution is Figure 1 and 5 as shown in the figure, that is, the threaded member 60 is rotatably arranged on the fixing member 70 and abuts against the fixing member 70. One end of the threaded member 60 with threads is in threaded transmission cooperation with the connecting member 50. By rotating the threaded member 60, the connecting member 50 is driven to approach or move away from the fixing member 70; the second technical solution is that the threaded member 60 is in threaded cooperation with the fixing member 70, and the end close to the connecting member 50 does not have threads and directly abuts against the connecting member 50. By rotating the threaded member 60, the distance that the threaded member 60 extends into the fixing member 70 (for example: the installation cavity 90) is adjusted, and then the connecting member 50 is pushed away from the fixing member 70.

[0048] As Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the microphone structure further includes a circuit board 80. The microphone device 30 is disposed on the circuit board 80 and electrically connected to the circuit board 80. The mounting end 32 is located on the side of the circuit board 80 facing the sealing support 40. The circuit board 80 is in abutting cooperation with the sealing support 40 and the sealing elastic member 20 respectively. The sealing support 40 has a sealing cavity 41 inside, and the mounting end 32 is located in the sealing cavity 41. Wherein, the sealing support 40 applies pressure to the sealing elastic member 20 through the circuit board 80 to compress the sealing elastic member 20.

[0049] By setting the circuit board 80 to be in abutting cooperation with the sealing support 40 and the sealing elastic member 20 respectively, not only can the sealing support 40 apply pressure to the sealing elastic member 20 through the circuit board 80 to compress the sealing elastic member 20 and the sealing support 40 respectively, but also the reliable operation of the microphone device 30 is ensured. By setting the sealing cavity 41, reliable sealing around the mounting end 32 of the microphone device 30 is achieved, and thus the microphone device 30 has good airtightness.

[0050] In a specific embodiment of the present invention, the circuit board 80 adopts a PCB circuit board, and the microphone device 30 is fixed on the PCB circuit board by a soldering circuit method to achieve reliable electrical connection with the circuit board 80.

[0051] As Figure 3 and Figure 5 shown, an installation cavity 90 is formed between the assembly structure member 10 and the fixing member 70. The sealing elastic member 20, the microphone device 30, the sealing support 40, and the connecting member 50 are respectively located in the installation cavity 90. One end of the threaded member 60 away from the threaded cooperation with the connecting member 50 is a rotating end 61, and the rotating end 61 passes through the fixing member 70 and extends to the outside of the installation cavity 90. Wherein, by rotating the rotating end 61, the connecting member 50 and the sealing support 40 are driven to approach or move away from the assembly structure member 10.

[0052] By setting the sealing elastic member 20, the microphone device 30, the sealing support 40, and the connecting member 50 to be respectively located in the installation cavity 90, reliable protection and centralized storage of the sealing elastic member 20, the microphone device 30, the sealing support 40, and the connecting member 50 are achieved. Furthermore, the overall microphone structure proposed by the present invention tends to be miniaturized and is more suitable for use on electronic devices (such as: tablet devices). By setting the rotating end 61 to pass through the fixing member 70 and extend to the outside of the installation cavity 90, it is convenient for the staff to manually operate the rotating end 61.

[0053] In a specific embodiment of the present invention, the assembly structure member 10 and the fixing member 70 can be respectively cooperated with an external housing to form a closed installation cavity 90, thereby further ensuring the airtightness of the microphone device 30.

[0054] AsFigure 1 , Figure 2 , Figure 3 and Figure 10 As shown in Figure 10 , the microphone structure further includes a rotating handle 100, which is detachably connected to the rotating end 61 and is used to drive the rotating end 61 to rotate; as Figure 9 shown, the threaded member 60 includes a threaded section 62, a stepped section 63, and a rotating section 64 that are sequentially connected along the axial direction. The threaded section 62 has an external thread for threaded cooperation with the connecting member 50. The stepped section 63 is located in the installation cavity 90 and is in abutting cooperation with the inner wall of the fixing member 70 to axially limit and seal the elastic member 20. The rotating section 64 passes through the fixing member 70 and extends to the outside of the installation cavity 90, and the rotating end 61 is located on the rotating section 64.

[0055] By setting the rotating handle 100 to be detachably connected to the rotating end 61, it is not only convenient for the staff to manually adjust the rotation of the rotating end 61, but also the rotating handle 100 can be quickly disassembled after the overall assembly of the microphone structure is completed, avoiding the rotating handle 100 occupying extra space, and thus the space occupied by the microphone structure proposed by the present utility model can be further reduced.

[0056] In a specific embodiment of the present utility model, when the rotating handle 100 does not need to be disassembled, as Figure 9 and Figure 10 shown, the mating groove 101 on the rotating handle 100 can be set to be in interference fit with the rotating end 61 to prevent the rotating handle 100 from disconnecting from the rotating end 61.

[0057] As Figure 1 , Figure 2 and Figure 5 shown, the fixing member 70 has a limiting groove 71; the connecting member 50 has a limiting protrusion 51, at least a part of the limiting protrusion 51 extends into the limiting groove 71, and is in limiting and guiding cooperation with the inner wall of the limiting groove 71; the limiting protrusion 51 has a threaded hole 52, and the threaded end of the threaded member 60 passes through the limiting groove 71 and at least a part of it is inserted into the threaded hole 52 to be in threaded driving cooperation with the threaded hole 52; or, the connecting member 50 has a limiting groove 71; the fixing member 70 has a limiting protrusion 51, at least a part of the limiting protrusion 51 extends into the limiting groove 71, and is in limiting and guiding cooperation with the inner wall of the limiting groove 71; the bottom wall of the limiting groove 71 has a threaded hole 52, and the threaded end of the threaded member 60 passes through the limiting protrusion 51 and at least a part of it is inserted into the threaded hole 52 to be in threaded driving cooperation with the threaded hole 52.

[0058] By setting the limiting protrusion 51 to be in limiting and guiding cooperation with the inner wall of the limiting groove 71, the reliability and smoothness of the relative movement between the fixing member 70 and the connecting member 50 are ensured.

[0059] AsFigure 1 , Figure 2 and Figure 5 As shown in Figure 1 , Figure 2 and Figure 5 , under the condition that the connecting piece 50 has a limiting protrusion 51, there is a cavity 53 inside the connecting piece 50, and the cavity 53 communicates with the threaded hole 52 for accommodating the part of the threaded piece 60 passing through the threaded hole 52; under the condition that the connecting piece 50 has a limiting groove 71, there is a cavity 53 inside the connecting piece 50, and the cavity 53 communicates with the threaded hole 52 for accommodating the part of the threaded piece 60 passing through the threaded hole 52.

[0060] By providing the cavity 53, not only the part of the threaded piece 60 passing through the threaded hole 52 is effectively accommodated, but also the overall weight of the connecting piece 50 is significantly reduced, effectively saving costs and facilitating processing and forming.

[0061] As Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown in Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the sealing elastic member 20 includes a fixing portion 21, a protruding portion 22 and a suction cup portion 23; the suction cup portion 23 is sleeved outside the protruding portion 22 or the fixing portion 21; the protruding portion 22 is fixedly connected to the fixing portion 21 and at least a part of it extends into the inside of the suction cup portion 23; one end of the fixing portion 21 away from the protruding portion 22 is in sealing cooperation with the sound pickup end 31; there is a microphone through hole 24 inside the sealing elastic member 20, and the microphone through hole 24 penetrates through the fixing portion 21 and the protruding portion 22 and is respectively communicated with the sound pickup end 31 and the sound pickup hole 11 at both ends; wherein, when the sealing elastic member 20 is in a compressed state, the part of the protruding portion 22 extending into the inside of the suction cup portion 23 is in abutting cooperation with the assembly structural member 10, and the suction cup portion 23 expands under pressure and is in abutting cooperation with the assembly structural member 10.

[0062] By providing that at least a part of the protruding portion 22 extends into the inside of the suction cup portion 23, the part of the protruding portion 22 extending into the inside of the suction cup portion 23 can be in abutting cooperation with the assembly structural member 10, effectively forming a first sealing structure; by providing the suction cup portion 23, a second sealing structure is effectively formed; through the above two sealing structures, the airtightness of the microphone device 30 is further improved.

[0063] As Figure 7 and Figure 8As shown, the sealing elastic member 20 is an integral structure and is made of silicone material or rubber material; the fixing portion 21 and the protruding portion 22 are cylindrical structures, and the suction cup portion 23 is an annular umbrella-shaped structure. The opening with the largest dimension on the annular umbrella-shaped structure faces the assembled structural member 10, so that when the sealing elastic member 20 is in a compressed state, the suction cup portion 23 unfolds in a ring shape; the microphone structure further includes a circuit board 80, and the microphone device 30 is arranged on the circuit board 80 and is electrically connected to the circuit board 80; one end of the fixing portion 21 away from the protruding portion 22 is fixedly connected to the circuit board 80 by an adhesive method; the circuit board 80 has a mounting groove 81, and at least a part of one end of the fixing portion 21 away from the protruding portion 22 extends into the mounting groove 81 and is in limit fit with the inner wall of the mounting groove 81.

[0064] By setting the sealing elastic member 20 as an integral structure and using silicone material or rubber material, it is not only convenient for the processing and forming of the sealing elastic member 20, but also ensures that the sealing elastic member 20 has reliable sealing performance; by setting the opening with the largest dimension on the annular umbrella-shaped structure to face the assembled structural member 10, the sealing elastic member 20 can gradually unfold in a ring shape under pressure, thereby effectively expanding the sealing area; by setting the mounting groove 81, it is further convenient for the precise installation of the sealing elastic member 20.

[0065] As Figure 1 and Figure 3 As shown, the connecting member 50 has a first guiding post 54, and the fixing member 70 has a first guiding hole 72. At least a part of the first guiding post 54 is inserted into the first guiding hole 72 and is in limit fit with the first guiding hole 72; the extending directions of the first guiding post 54 and the first guiding hole 72 are respectively parallel to the relative movement direction of the connecting member 50 and the fixing member 70; alternatively, the connecting member 50 has a first guiding hole 72, and the fixing member 70 has a first guiding post 54.

[0068] By setting the above three alternative parallel technical solutions, the positioning and fitting accuracy among the connecting member 50, the sealing and supporting member 40, and the circuit board 80 is further improved.

[0069] In a specific embodiment of the present utility model, an adhesive tape (for example: at the position marked 21 in Figure 8 an adhesive tape can be pasted on the plane) is adhered to the back surface of the sealing elastic member 20 for fixed installation in the installation groove 81 of the circuit board 80.

[0070] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a microphone device 30, a sound pickup hole 11, and a sealing elastic member 20 form a set of sound pickup components. There are multiple sets of sound pickup components, which are arranged at intervals; the microphone structure further includes a circuit board 80 and a main electrical connector 110. The microphone devices 30 in the multiple sets of sound pickup components are arranged at intervals on the circuit board 80 and are respectively electrically connected to the main electrical connector 110 through the circuit board 80; the main electrical connector 110 is used for electrical connection with an external terminal; the sealing support member 40 has a protection cavity 43 inside, and the main electrical connector 110 is located in the protection cavity 43.

[0071] By arranging multiple sets of sound pickup components, a microphone array is formed. Then, through the cooperative work of the multiple microphone devices 30 and in combination with existing positioning and recognition algorithms and noise reduction algorithms, the microphone structure can more clearly identify the source and location of external sounds and can eliminate noise from the picked-up sounds.

[0072] It should be noted that: in a specific embodiment of the present invention, as Figure 1 、 Figure 3 and Figure 5 shown, the threaded section 62 of the threaded member 60 passes through the opening on the fixing member 70 and is in threaded driving connection with the threaded hole 52 on the limiting protrusion 51. The rotating handle 100 is fixed on the rotating end 61, and the stepped section 63 abuts against the inner wall of the limiting groove 71 to transmit force; the circuit board 80 and the multiple microphone devices 30 are completed by welding and encapsulation, so that there is a good connection between the circuit board 80 and the multiple microphone devices 30; as Figure 8 shown, the fixing portion 21 of the sealing elastic member 20 is adhesively fixed in the corresponding mounting groove 81 on the circuit board 80 through back glue; after the threaded member 60 is assembled, the connecting member 50 is adhesively fixed to the sealing support member 40 through back glue, and then the circuit board 80 is adhesively connected to the sealing support member 40 correspondingly to achieve overall assembly; the back glue layer at the bonding position will further prevent external noise from entering the microphone device 30 from all directions, effectively improving the airtightness of the microphone device 30.

[0073] As Figure 6 shown, the present invention provides an electronic device. The electronic device includes the above-mentioned microphone structure; the electronic device further includes a display screen 120, and the orientation of the sound pickup hole 11 of the assembly structure member 10 is the same as the display direction of the display screen 120.

[0074] By setting the orientation of the sound pickup hole 11 of the assembly structure member 10 to be the same as the display direction of the display screen 120, the sound source localization accuracy of the microphone structure and the quality of the picked-up sound are further improved.

[0075] Now, the specific working process and principle of the present invention are described in detail as follows:

[0076] As Figure 2, Figure 3 and Figure 5 As shown in Figure 3 and Figure 5 , the circuit board 80 carrying the microphone device 30 is fixed between the assembly structure member 10 and the sealing support member 40. At this time, when the rotary handle 100 is rotated, the threaded member 60 drives the connecting member 50 to move towards the assembly structure member 10, compressing the sealing support member 40 and the circuit board 80. The circuit board 80 transmits the pressure to the sealing elastic member 20, driving the protruding portion 22 and the suction cup portion 23 to be respectively pressed against the assembly structure member 10. The circular umbrella-shaped structure on the suction cup portion 23 unfolds, and a sealed space is formed between it and the inner wall of the assembly structure member 10. Thus, the protruding portion 22 and the suction cup portion 23 together form two sealing layers, and the sealing of the entire microphone structure is completed, effectively ensuring the airtightness of the microphone sound channel and isolating external noise from entering the microphone sound channel from the side of the microphone device 30;

[0077] Sound source localization process: Multiple microphone devices 30 form an array. The sound sizes and reception times received through multiple sound pickup holes 11 are different. By processing the sound size and reception time data and using existing localization algorithms, the pronunciation position of the sound can be determined; In the present utility model, the airtightness of the microphone channel is very good, preventing sound from entering different microphone devices 30 from the side of the microphone device 30, thus ensuring the accuracy of the determination result.

[0078] Echo cancellation process: In the present utility model, the airtightness of the microphone channel is very good, and sound-absorbing materials can be used to absorb more echoes structurally, preventing the echoes from being received by the microphone device 30 again, and thus realizing partial or complete cancellation of the echoes.

[0079] In summary, the present utility model provides a microphone structure and an electronic device. By arranging the cooperation of the connecting member 50, the threaded member 60 and the fixing member 70, the present utility model not only realizes the adjustment of the tight sealing degree of the sealing elastic member 20 and the sealing support member 40 with a simple structure, but also ensures that the sealing elastic member 20 and the sealing support member 40 will not become loose during long-term use, thereby ensuring the reliable sealing of the microphone device 30; by arranging the sealing elastic member 20 to be hermetically sealed with the sound pickup end 31 and the assembly structural member 10 respectively, the reliable sealing of the sound pickup end 31 is ensured; by arranging the interior of the sealing elastic member 20 to be communicated with the sound pickup end 31 and the sound pickup hole 11 respectively, the reliable sound pickup of the microphone device 30 for external sounds is ensured; by arranging the sealing support member 40 to be in abutting cooperation with the connecting member 50 and covering the outside of the mounting end 32, the sealing of the mounting end 32 is realized, and combined with the sealing elastic member 20, the all-round reliable sealing of the microphone device 30 is realized, so that the microphone device 30 has good airtightness, thereby improving the accuracy of sound source localization and echo cancellation of the microphone device 30 in terms of structure, and can exclude the interference of external noises on the microphone device 30, ensuring the precise and reliable operation of the microphone device 30; in actual use, it is found that when using the microphone structure proposed by the present utility model, the airtightness of the microphone device 30 can reach more than 20 dB, and external sounds can basically only enter from the sound pickup hole 11, so that the microphone device 30 can more clearly identify the sound source; the structure of the present utility model is simple and the cost is low, which is convenient for assembly and subsequent maintenance, and is suitable for large-scale promotion and use on electronic devices.
