[0053] In order to better understand the above technical solution, the example embodiments of the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited to the exemplary embodiments described here.

[0054] In general, the microphone vibration damping bracket disclosed in the present application has one end for supporting the microphone and the other end for being fixedly mounted on the PCB circuit board. Moreover, after installation, the microphone vibration damping bracket can make the sensing diaphragm of the microphone be vertically arranged with the PCB circuit board, so as to better solve the vibration problem of the PCB circuit board.

[0055] Figure 1 This is a schematic diagram of the exploded structure of the sound pickup device. Figure 2 This is a schematic diagram of the structure of the microphone vibration reduction bracket. Figure 1 , Figure 2 An embodiment of the present application discloses a microphone vibration reduction bracket, which includes a bearing portion 10 and a plug-in portion 20. The bearing portion 10 includes a bearing slot 11 for bearing a microphone 100. The height direction of the bearing slot 11 is arranged along a first direction X, so that after being placed in the bearing slot 11, the sensing diaphragm of the microphone 100 is arranged perpendicular to the first direction X; the plug-in portion 20 extends from the bearing portion 10 along the first direction X; wherein the plug-in portion 20 is used to be plugged into and fixed to an end of a PCB circuit board 200, so that the sensing diaphragm is arranged perpendicular to the PCB circuit board 200.

[0056] Specifically, the bearing part includes a bearing groove, which is, for example, cylindrical, and the height direction or depth direction of the bearing groove is arranged along the first direction; the microphone, such as an electret microphone, is usually a cylindrical structure; in this way, when the microphone is placed in the bearing groove, the sensing diaphragm of the microphone (such as an electret diaphragm) is arranged perpendicular to the first direction.

[0057] Specifically, the plug-in portion is connected to the bearing portion and extends along the first direction, and then the other end of the plug-in portion is used to be plugged into and fixed to the circumferential end of the PCB circuit board; Figure 1 It can be seen that, in this way, the microphone can be suspended relative to the PCB circuit board; and the sensing diaphragm of the microphone is vertically arranged to the PCB circuit board, or in other words, the plane where the sensing diaphragm of the microphone is located is vertically arranged to the plane where the PCB circuit board is located.

[0058] It can be understood that sound waves are usually longitudinal waves. When the PCB circuit board vibrates due to buttons, etc., most of the noise caused by the vibration will propagate in a direction perpendicular to the PCB circuit board. The microphone vibration reduction bracket of this embodiment arranges the sensing diaphragm of the microphone to be perpendicular to the PCB circuit board. In this way, the suspended microphone sensing diaphragm will greatly reduce or will not pick up the above-mentioned noise, thereby reducing the risk of noise being picked up and well solving the vibration filtering problem of the PCB circuit board.

[0059] In addition, see Figure 4 It should also be noted that the length of the plug-in part in the microphone vibration reduction bracket affects the keep-out distance M between the microphone and the PCB circuit board. That is to say, by adjusting the length of the plug-in part, a sufficient keep-out distance M on the microphone pickup path can be set, thereby ensuring a better pickup effect.

[0060] Continue to view Figure 1 , Figure 2 , Figure 1 , Figure 2 A structure is provided in which a pair of plug-in parts are arranged in pairs on opposite sides of a load-bearing part; of course, in other embodiments, it can be understood that only one plug-in part may be provided, and one plug-in part may be provided in the middle position of one end of the load-bearing part; or there may be other structural forms, which are not limited in this embodiment.

[0061] An embodiment of the present application provides a microphone vibration reduction bracket and a sound pickup device, wherein the microphone vibration reduction bracket includes a bearing portion and a plug-in portion, wherein the bearing portion is provided with a bearing groove for bearing a microphone, and the height direction of the bearing groove is arranged along a first direction, so that after the microphone is placed in the bearing groove, the sensing diaphragm of the microphone is arranged perpendicular to the first direction; and the plug-in portion extends from the bearing portion along the first direction, so that after the plug-in portion is plugged into the end of a PCB circuit board, the sensing diaphragm of the microphone is arranged perpendicular to the PCB circuit board.

[0062] In this way, it can be understood that, considering that sound waves are usually longitudinal waves, the noise caused by vibration of the PCB circuit board due to buttons, etc. will mostly propagate in a direction perpendicular to the PCB circuit board. In this embodiment, the sensing diaphragm of the microphone is set vertically to the PCB circuit board through a vibration-damping bracket, which can minimize the microphone's pickup of noise caused by vibration of the PCB circuit board, and effectively solve the microphone's vibration filtering problem.

[0063] In other words, compared with the related solutions in which a vibration-damping bracket is used to set the sensing diaphragm of the microphone parallel to the PCB circuit board, the microphone vibration-damping bracket of this embodiment can set the sensing diaphragm of the microphone vertically to the PCB circuit board after installation, thereby better filtering out the noise caused by vibration of the PCB circuit board and ensuring the sound pickup effect of the microphone.

[0064] Regarding the specific structure of the above-mentioned plug-in portion 20, in a possible implementation manner, the plug-in portion 20 includes an elastic arm 21 and an elastic column 22; wherein the elastic arm 21 extends along the first direction X, one end of the elastic arm 21 is connected to the bearing portion 10, and the other end of the elastic arm 21 is connected to the elastic column 22; the axial direction of the elastic column 22 is perpendicular to the plane where the PCB circuit board 200 is located, and the elastic column 22 is used to be plugged in and fixed to the end of the PCB circuit board 200.

[0065] Specific reference Figure 2 The plug-in portion includes an elastic arm extending along a first direction and an elastic column extending along a second direction, wherein the second direction is perpendicular to the first direction, that is, perpendicular to the plane where the PCB circuit board is located; then, the plug-in portion is specifically plugged and fixed to the circumferential end of the PCB circuit board through the elastic column at the end.

[0066] It can be understood that, through the above arrangement, the elastic column forms a first-level vibration reduction structure for the PCB circuit board, and the elastic arm forms a second-level vibration reduction structure for the PCB circuit board; in other words, the elastic column and the elastic arm can reduce vibration for the PCB circuit board from two directions perpendicular to each other, and the vibration reduction effect is obvious.

[0067] Regarding the specific plug-in structure of the elastic column 22, in a specific embodiment, along the axial direction, the elastic column 22 includes a first limiting portion 221, a second limiting portion 222, and an elastic connecting portion 223 located between the first limiting portion 221 and the second limiting portion 222; wherein, the diameter of the elastic connecting portion 223 is smaller than the diameter of the first limiting portion 221, and the diameter of the elastic connecting portion 223 is smaller than the diameter of the second limiting portion 222, so that after the elastic connecting portion 223 is inserted into the plug-in slot 201 at the end of the PCB circuit board 200, the first limiting portion 221 and the second limiting portion 222 are elastically abutted against two opposite surfaces of the PCB circuit board 200 respectively.

[0068] First see Figure 3 A plug-in slot 201 may be provided at a circumferential end of the PCB circuit board 200 . The plug-in slot 201 extends inward from the circumferential end of the PCB circuit board 200 , and a limiting circular hole 2011 is formed at the end of the plug-in slot 201 .

[0069] Then, return to Figure 2In this embodiment, the elastic column can be specifically set as a three-section structure, that is, the diameter of the middle section (elastic connecting part 223) is smaller than the diameters of the upper and lower sections (the first limiting part 221 and the second limiting part 222), wherein the diameters of the upper and lower sections (the first limiting part 221 and the second limiting part 222) can be equal; or in other words, in this embodiment, a ring-shaped groove can be formed by reducing the diameter of the middle section (elastic connecting part 223) of the elastic column.

[0070] It can be understood that, in this way, the elastic column 22 can use the elastic connecting part 223 of the middle section to be inserted into the above-mentioned plug-in slot 201. When inserted, the elastic connecting part 223 will first be squeezed forward in the path of the plug-in slot 201, and then the stress will be released at the limiting circular hole 2011 at the end of the plug-in slot 201, and the elastic column 22 will be embedded in the PCB circuit board 200; at this time, it can be understood that the first limiting part 221 and the second limiting part 222 can be elastically abutted against the two opposite surfaces of the PCB circuit board 200 respectively.

[0071] Here, it should be noted that the middle section mentioned above does not mean that the elastic connection part is located in the middle of the elastic column in the height direction, but only means that it is located between the upper and lower sections.

[0072] In a specific embodiment, it can be understood that in order to ensure the stability of the insertion, the height of the elastic connection part 223 (i.e., the length along the second direction Y) should not be greater than the thickness of the PCB circuit board 200; for example, if the thickness of the PCB circuit board 200 is 5 mm, then the height of the elastic connection part 223 can be slightly less than 5 mm, for example, 4 mm.

[0073] In addition, combined with the above-mentioned fact that the elastic connection part 223 will be squeezed forward in the path of the plug-in slot 201, the diameter of the elastic connection part 223 should be greater than the width of the plug-in slot 201 on the PCB circuit board 200. It can be understood that the greater than here should be understood as slightly greater than. For example, the diameter of the elastic connection part 223 is 10 mm. At this time, the width of the plug-in slot 201 on the PCB circuit board 200 can be set to 9.5 mm, etc.

[0074] Regarding the specific structure of the above-mentioned plug-in portion 20, in another possible implementation manner, see Figure 1 and 2A pair of plug-in parts can be arranged in pairs on opposite sides of the bearing part, and the plug-in parts (specifically, the elastic arms mentioned above) can be in an arc shape extending along the first direction X. Then, a reinforcing rib 23 extending along the first direction X can be provided on the inner side of the plug-in part 20 (specifically, the elastic arms 21 mentioned above); wherein, along the second direction Y perpendicular to the plane where the PCB circuit board 200 is located, the reinforcing rib 23 can usually be located in the middle position of the plug-in part 20, or in other words, located in the middle position in the width direction of the plug-in part, to ensure the elastic suspension effect.

[0075] In addition, combined with the above-mentioned elastic column 22 that needs to be inserted into the above-mentioned plug-in slot 201 using the elastic connecting part 223, in order to ensure a smooth insertion process, it can be understood that along the second direction Y perpendicular to the plane where the PCB circuit board 200 is located, the reinforcing rib 23 should be staggered with the elastic connecting part 223, or in other words, along the width direction of the plug-in part 20, the reinforcing rib 23 should be staggered with the elastic connecting part 223 to prevent the reinforcing rib from blocking the PCB circuit board 200 during the insertion process.

[0076] Please combine the specific Figure 2 To ensure the above-mentioned staggered arrangement, it can be seen that the elastic connection portion 223 can be located at a lower middle position in the height direction of the elastic column 22, and of course, can also be located at a higher middle position.

[0077] In one possible implementation, a pair of plug-in portions may be arranged in pairs on opposite sides of the bearing portion, and a cable opening 12 is provided at one end of the bearing portion 10 close to the plug-in portion 20 , for allowing a cable connecting the microphone 100 and the PCB circuit board 200 to pass through.

[0078] That is to say, a cable opening can be set at one end of the bearing portion facing the plug-in portion. In this way, combined with the arrangement of a pair of plug-in portions located on opposite sides of the bearing portion, the cable of the microphone can pass through the cable opening and be connected to the PCB circuit board. At this time, the cable can pass through the middle of the pair of plug-in portions, or in other words, the cable can be routed from the inside of the microphone vibration damping bracket without having to be routed from the outside of the microphone vibration damping bracket.

[0079] In addition, to facilitate installation of the microphone, an opening may be provided at one end of the carrying portion facing away from the plug-in portion to facilitate placement of the microphone into the carrying slot.

[0080] In a possible implementation manner, the bearing portion 10 and the plug-in portion 20 may be made of, for example, silicone material and may be integrally formed.

Of course, according to actual needs, the PCB circuit board can also be installed with two or more microphone vibration reduction brackets.

[0083] In one possible implementation, a plug-in slot 201 is provided at the end of the PCB circuit board 200, and the plug-in slot 201 is used for plugging in the elastic connection part 223 of the plug-in part 20, and the elastic connection part 223 extends in a direction perpendicular to the plane where the PCB circuit board 200 is located; wherein the plug-in slot 201 extends inward from the circumferential end of the PCB circuit board 200, and a limiting circular hole 2011 is formed at the end of the plug-in slot 201.

[0084] In one possible implementation, the device housing includes a handheld shell 300 and a top cover 400; wherein the handheld shell 300 extends along a first direction X, a PCB circuit board 200 is installed inside the handheld shell 300, and the top cover 400 is used to cover one end of the handheld shell 300 along the first direction X; and an elastic support member 500 is provided on the inner side of the top cover 400, and the elastic support member 500 is, for example, a PU sponge net, so that when the handheld shell 300 is shaken, the elastic support member 500 is used to abut against the microphone vibration reduction bracket. At the same time, the microphone vibration reduction bracket can adjust the position of the microphone 100 through its own elastic arm, so that the microphone 100 as a whole is still in a suspended state.
