[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a microphone, including a bracket 2, a threaded fastener 3 and a top cover 1. A connecting ring 21 is provided at the top end of the bracket 2. A connecting hole 22 is provided on the connecting ring 21 and passes through the length direction of the microphone. A threaded blind hole 14 connected to the connecting hole 22 is provided on the side of the top cover 1 facing the bracket 2.

[0029] The threaded fastener 3 passes through the connecting hole 22 and is threadedly connected to the threaded blind hole 14 .

[0030] Since the threaded blind holes 14 are formed on the back of the top cover 1, when installing the top cover 1 on the bracket 2, it is only necessary to flip the bracket 2 upside down on the top cover 1, and the threaded fasteners 3 pass through the connecting holes 22 on the connecting ring 21 from the side of the connecting ring 21 to connect with the threaded blind holes 14. Compared to the prior art, in which the screw holes are formed on the top of the top cover 1, the top cover 1 is installed upright on the bracket 2, and the screws pass through the top side of the top cover 1 to the bracket 2, requiring a decorative plate to be provided on the top cover 1 to cover the threaded holes, the threaded blind holes 14 in this application are formed on the back of the top cover 1, and the threaded fasteners 3 are hidden on the back of the top cover 1. Therefore, there is no need to provide a decorative plate, achieving structural optimization, reducing costs, and reducing the size of the microphone.

[0031] In the microphone of the present invention, since the threaded blind hole 14 is provided on the side of the top cover 1 near the bracket 2, when installing the top cover 1 on the bracket 2, it is only necessary to flip the bracket 2 upside down onto the top cover 1, and the threaded fastener 3 passes through the connecting hole 22 on the connecting ring 21 from the side of the connecting ring 21 to connect with the threaded blind hole 14. Compared to the prior art, in which the screw hole is formed on the top of the top cover 1, and a decorative plate is required on the top cover 1 to cover the screw hole, the threaded blind hole 14 in the present application is formed on the back of the top cover 1, and the threaded fastener 3 is hidden on the back of the top cover 1. Therefore, the need for a decorative plate is eliminated, achieving structural optimization and reducing costs.

[0032] In one embodiment, if Figure 2 and Figure 5 As shown, there are two connecting holes 22, which are arranged opposite to each other along the radial direction of the connecting ring 21. Correspondingly, there are two threaded blind holes 14, which correspond to the two connecting holes 22 in a one-to-one manner.

[0033] In one embodiment, the threaded fastener 3 is a screw.

[0034] In other embodiments, the threaded fastener 3 may include a screw and a nut.

[0035] In one embodiment, a circumferential positioning structure is provided between the top cover 1 and the bracket 2 , and the circumferential positioning structure is used to limit the circumferential movement of the bracket 2 relative to the top cover 1 .

[0036] After the bracket 2 is buckled upside down on the top cover 1 with the connecting hole 22 aligned with the threaded blind hole 14, the circumferential positioning structure limits the circumferential movement of the bracket 2, which is beneficial for the preliminary positioning of the bracket 2 and the top cover 1, improves the preliminary positioning efficiency of the top cover 1 and the connecting ring 21, and is beneficial for locking the threaded fastener 3.

[0037] In one embodiment, if Figure 2 and Figure 4 As shown, the top cover 1 includes a cover plate 11 and a limiting protrusion 12 connected to the outer edge of the cover plate 11 . The inner end surface of the cover plate 11 and the inner wall surface of the limiting protrusion 12 together form an inner cavity of the top cover 1 .

[0038] The threaded blind hole 14 is provided on the cover plate 11 , the circumferential positioning structure is a hook 16 provided on the limiting protruding ring 12 , and the connecting ring 21 is inserted into the inner cavity of the top cover 1 and engaged with the hook 16 .

[0039] It only needs to arrange the hook 16 on the top cover 1, which has a simple structure and is easy to install.

[0040] In one embodiment, if Figure 4 As shown, two hooks 16 are provided, and the two hooks 16 are arranged opposite to each other along the radial direction of the connecting ring 21 .

[0041] In one embodiment, if Figure 4 As shown, a guide surface is provided on the side of the hook 16 close to the connecting ring 21 , and the guide surface is inclined toward the side close to the cover plate 11 , for guiding the connecting ring 21 to engage with the hook 16 .

[0042] In one embodiment, if Figure 4 As shown, a screw hole column 15 protruding toward the bracket 2 is provided on the side of the top cover 1 facing the bracket 2, and a threaded blind hole 14 is provided on the screw hole column 15 to reduce the thickness of the rest of the top cover 1 and improve the sensitivity of the touch buttons on the top cover 1.

[0043] In one embodiment, if Figure 2 and Figure 3 As shown, a positioning groove 23 is provided near the opening of the threaded blind hole 14 in the connection hole 22. The shape of the positioning groove 23 matches the shape of the screw hole column 15, and the screw hole column 15 is restrained in the positioning groove 23. After the bracket 2 is buckled onto the top cover 1 and the screw hole column 15 is aligned and inserted into the positioning groove 23, the positioning groove 23 can restrict the movement of the screw hole column 15 to achieve preliminary positioning, which facilitates the smooth passage of the threaded fastener 3 through the connection hole 22 and into the threaded blind hole 14.

[0044] In one embodiment, if Figure 3 As shown, the screw hole column 15 is cylindrical, and the positioning groove 23 is a circular groove adapted to the shape of the screw hole column 15. When the circular screw hole column 15 is inserted into the positioning groove 23, there is no need to distinguish the insertion direction, which facilitates the screw hole column 15 to be inserted into the positioning groove 23.

[0045] In other embodiments, the screw hole column 15 may be a prism or a frustum.

[0046] In one embodiment, if Figure 5 As shown, a recessed groove 24 is provided at the opening of the connecting hole 22 facing away from the threaded blind hole 14 , and the recessed groove 24 is used to accommodate the end of the threaded fastener 3 to prevent the end of the threaded fastener 3 from being exposed to the outside and interfering with other parts in the microphone.

[0047] In one embodiment, the recessed groove 24 is a U-shaped groove having an opening extending through the radially outer sidewall of the connecting ring 21. After the integral bracket 2 is injection molded, the recessed groove 24 needs to be machined. During machining, the recessed groove 24 can be machined horizontally from the side of the connecting ring 21. Compared to machining from the direction of screw tightening, the recessed groove 24 is free from other structures on the side of the connecting ring 21, leaving more space and fewer limitations. This prevents mechanical interference of the recessed groove 24 with other structures on the bracket 2.

[0048] In one embodiment, if Figure 2As shown, it also includes a touch circuit board 4 and a conductive spring 5. The touch circuit board 4 and the conductive spring 5 are installed in the inner cavity of the top cover 1. A touch area 13 is provided on the top cover 1. One end of the conductive spring 5 abuts against the inner surface of the touch area 13, and the other end of the conductive spring 5 abuts against the touch circuit board 4 and is electrically connected to the touch circuit board 4.

[0049] When the touch area 13 is pressed, the conductive spring 5 is compressed to trigger the corresponding function of the microphone.

[0050] Specifically, after the touch area 13 is subjected to force, the pressure is transmitted to the conductive spring 5, triggering the corresponding function. If the user mistakenly operates the part outside the touch area 13, the touch area 13 is not subjected to force or the pressure is relatively small, and the corresponding function cannot be triggered. The setting of the conductive spring 5 can improve the operation sensitivity of the touch area 13.

[0051] Because the top cover 1 is closer to the sound pickup cavity within the bracket 2, the touch buttons can avoid mechanical noise, which affects the sound pickup effect. In addition, the top cover 1 in this application omits the decorative plate, which facilitates the transmission of pressure from the touch area 13 to the conductive spring 5 to trigger the corresponding function when it is pressed, thereby increasing the sensitivity of the touch area 13.

[0052] In one embodiment, two touch areas 13 are provided, namely a silent touch area and a microphone noise reduction touch area, and two conductive springs 5 ​​are provided, namely a first conductive spring and a second conductive spring.

[0053] One end of the first conductive spring abuts against the inner surface of the mute touch area, and the other end of the first conductive spring is electrically connected to the touch circuit board 4. When the mute touch area is pressed, the first conductive spring is compressed to trigger the mute function of the microphone.

[0054] One end of the second conductive spring abuts against the inner surface of the noise reduction touch area 13, and the other end of the second conductive spring is electrically connected to the touch circuit board 4. When the noise reduction touch area 13 is pressed, the second conductive spring is compressed to trigger the noise reduction function of the microphone.

[0055] In other embodiments, the touch area 13 may be a mute touch area or a microphone noise reduction touch area. When the mute touch area is pressed, the conductive spring 5 is compressed to trigger the mute function of the microphone.

[0056] When the microphone noise reduction touch area is pressed, the conductive spring 5 is compressed to trigger the noise reduction function of the microphone.

[0057] In one embodiment, if Figure 4As shown, a support protrusion 17 protruding toward one side of the bracket 2 is provided on the inner end surface of the top cover 1, and the support protrusion 17 abuts the end surface of the connecting ring 21 to form an installation space for accommodating the touch circuit board 4 between the connecting ring 21 and the inner end surface of the top cover 1.

[0058] In one embodiment, the support protrusion 17 includes a plurality of ribs spaced apart along the circumference of the limiting protrusion ring 12 . The ribs connect the inner wall surface of the limiting protrusion ring 12 and the inner end surface of the cover plate 11 . The ribs support the end surface edge of the connecting ring 21 .

[0059] In one embodiment, if Figure 4 As shown, a guide groove 18 is provided on the inner end surface of the top cover 1 at a position corresponding to the touch area 13 , and the conductive spring 5 is installed in the guide groove 18 . The guide groove 18 is used to guide the deformation of the conductive spring 5 .

[0060] In one embodiment, a guide cylinder is provided on the inner end surface of the top cover 1 and protrudes toward the side close to the bracket 2 , and the inner hole of the guide cylinder forms the guide groove 18 .

[0061] In other embodiments, the circumferential positioning structure may include a positioning column arranged on the inner end surface of the cover plate 11 and a positioning hole arranged on the connecting plate. The positioning column extends along the inverted direction of the bracket 2. When the bracket 2 is inverted on the top cover 1, the positioning column is inserted into the positioning hole.

[0062] In other embodiments, the sink 24 may be circular, and the sink 24 only has an opening facing one side of the bracket 2 .

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
