Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to an electrical connection mechanism and a microphone. Background Art

[0002] The microphone assembly production process is a series of orderly steps used to assemble the various components of the microphone into the final product. These processes include key links such as material preparation, parts assembly, configuration testing, quality control and inspection. An efficient production process can improve production capacity, ensure product quality, and meet market demand.

[0003] The microphone includes a sound pickup mechanism and a control mechanism. The user uses the control mechanism to adjust and control the electrical signal output by the sound pickup mechanism, for example, gain adjustment, monitoring headphone volume adjustment, etc. With the development of science and technology and the increasing demand of the consumer market, existing microphones have also added one-button mute, one-button noise reduction and other functions. In order to cater to consumer usage habits and the overall appearance of the microphone, these functions are mostly designed on the top cover of the microphone.

[0004] In order to reduce the size of the microphone, the button circuit designed on the top cover and used for effects such as microphone closure and noise reduction needs to be electrically connected to the control mechanism, such as power supply, MCU signal feedback, etc. Therefore, the top cover circuit and the control mechanism need to be electrically connected through a transmission wire.

[0005] However, the transmission wire has a certain volume, and directly hanging it in the pickup cavity will have a certain interference effect on the pickup effect, which is not conducive to the stable presentation of the pickup effect; and the transmission wire needs to be perforated in the pickup cavity to facilitate its extension to the preset position. The perforated structure will cause the pickup cavity to be affected by mechanical noise from the outside or the control mechanism. Utility Model Content

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not used to limit this application.

[0032] First, as Figure 1-2 As shown, the utility model discloses an electrical connection mechanism, including: a middle connecting ring 1, a top cover connecting ring 2 and a bottom connecting frame 3, a microphone bracket 4 is installed on the middle connecting ring 1, and a microphone 5 is installed on the microphone bracket 4, the top cover connecting ring 2 and the bottom connecting frame 3 are respectively arranged on the upper and lower sides of the middle connecting ring 1, the top cover connecting ring 2 and the middle connecting ring 1 are parallel to each other, and are connected by a connecting column 6, and a pickup cavity is formed between the top cover connecting ring 2 and the middle connecting ring 1, and the microphone 5 is located in the pickup cavity, a control unit 7 is installed on the top cover connecting ring 2, and a The PCB control board 8 and the FPCB 9 are mounted on the connecting column 6 and are electrically connected to the control unit 7 and the PCB control board 8, respectively. This can reduce the space occupied by the FPCB 9 in the sound pickup cavity and weaken the spatial impact of the FPCB 9 on the sound pickup cavity. At the same time, the signal transmission efficiency between the control unit 7 and the PCB control board 8 is guaranteed. The traditional transmission wire is replaced with the FPCB 9, which solves the technical problem in the prior art that the transmission wire has a certain volume and is directly suspended in the sound pickup cavity, which will have a certain interference effect on the sound pickup effect and is not conducive to the stable presentation of the sound pickup effect.

[0033] In one embodiment, Figure 1 、 3 As shown, the central connecting ring 1 is provided with an FPCB through-hole 10 for the FPCB 9 to pass through, facilitating the connection between the FPCB 9 and the control unit 7 on the top cover connecting ring 2 and the PCB control board 8 on the bottom connecting frame 3. In this embodiment, the control unit 7 may be a button for providing an indication signal to the PCB control board 8 or an indication structure driven by the PCB control board 8. Integrating the control unit 7 into the microphone's top cover makes it more easily visible and accessible to the user, effectively improving the microphone's ease of operation.

[0034] It is worth noting that the traditional microphone control parts are mostly integrated on the side walls of the microphone housing, such as gain adjustment, volume adjustment, etc. With the development of science and technology, microphones are gradually equipped with functions such as one-button microphone mute, sound pickup and noise reduction. The microphone mute function and noise reduction on function in the existing technology are mostly integrated in the terminal application of the electrically connected microphone, which is not convenient to use. The electrical connection structure provided in the embodiment of the present invention separates the control unit and the PCB control board controlled by the control unit at the top and middle position of the microphone, effectively utilizing the overall space of the microphone, realizing structural optimization, and helping to improve the practicality of the microphone.

[0035] In one embodiment, Figure 1 、 3 As shown, the microphone bracket 4 can seal the FPCB through hole 10.

[0036] Specifically, when the microphone bracket 4 is installed on the middle connecting ring 1, the microphone bracket 4 fits tightly on the FPCB through hole 10, effectively sealing the FPCB through hole 10, and having the effect of sound insulation and noise reduction of the pickup cavity.

[0037] In one embodiment, Figure 3 As shown, the inner hole of the middle connecting ring 1 is formed as a microphone mounting hole 11 for mounting the microphone bracket 4.

[0038] Specifically, the inner hole of the middle connecting ring 1 matches the bottom end of the microphone bracket 4, so that the bottom end of the microphone bracket 4 can be installed in the inner hole of the middle connecting ring 1. There is no need to set up an additional mounting structure of the microphone bracket 4 on the middle connecting ring 1. The structural strength of the middle connecting ring 1 can be improved, while avoiding the impact on the space of the pickup cavity and facilitating the assembly of the microphone bracket 4.

[0039] In one embodiment, Figure 1 As shown, the bottom end of the microphone bracket 4 is snap-fitted to the microphone mounting hole 11 , which facilitates the assembly of the microphone bracket 4 .

[0040] In one embodiment, the microphone bracket 4 is integrally formed of an elastic material, such as silicone; after the assembler overcomes the material elasticity of the microphone bracket 4 and installs the microphone bracket 4 in the inner hole of the middle connecting ring 1, the microphone bracket 4 recovers its shape and is tightly clamped on the inner hole of the middle connecting ring 1; the elastic material structure also has a certain buffering effect on the internal noise of the pickup cavity, thereby preventing the microphone bracket from being affected by sound waves and generating mechanical vibration, which leads to damage to the sound pickup effect.

[0041] In one embodiment, Figure 4As shown, the microphone bracket 4 includes a snap-fit ​​seat 41, a connecting portion 42 and a microphone mounting portion 43. The snap-fit ​​seat 41 is snap-fitted to the inner hole of the middle connecting ring 1 and is used to seal the FPCB through hole 10. The connecting portion 42 is arranged on one side of the snap-fit ​​seat 41 and extends toward the side of the top cover connecting ring 2. The microphone mounting portion 43 is arranged at one end of the connecting portion 42 away from the snap-fit ​​seat 41, and the microphone 5 is mounted in the microphone mounting portion 43. In this embodiment, the snap-fit ​​seat 41, the connecting portion 42 and the microphone mounting portion 43 are all made of silicone material. The connecting portion 42 is provided with a snap-fitting groove structure, and the connecting portion 42 is clamped in the inner hole of the middle connecting ring through the snap-fitting groove, and the bottom notch edge and / or the top notch edge of the snap-fitting groove extend toward the FPCB through-hole 10 until the PFCB through-hole 10 is covered; the elastic properties of the connecting portion 42 achieve stable sealing of the FPCB through-hole 10, which is beneficial for preventing mechanical noise below the middle connecting ring from being transmitted to the pickup cavity. At the same time, not only can the FPCB through-hole 10 be sealed, but the elastic properties also facilitate the installation of the microphone bracket 4.

[0042] In one embodiment, Figure 4 As shown, the clamping seat 41 includes an upper plate 411, a lower plate 412 and a connecting seat 413. The upper plate 411 and the lower plate 412 respectively correspond to the upper edge and the lower edge of the clamping groove of the connecting portion 42. The upper plate 411 and the lower plate 412 are respectively arranged on both sides of the connecting seat 413. The connecting seat 413 matches the inner hole of the middle connecting ring 1. When the connecting seat 413 is located in the inner hole of the middle connecting ring 1, the upper plate 411 and the lower plate 412 are respectively tightly fitted with the two sides of the middle connecting ring 1 to ensure the stability of the microphone bracket 4.

[0043] The upper plate and / or the lower plate extend in the direction of the connecting column until they cover the FPCB through-hole located on one side of the microphone mounting hole. During the installation process, the operator linearly inserts the FPCB into the FPCB through-hole and then installs the microphone bracket in the microphone mounting hole. In this way, the upper plate and / or the lower plate can press the FPCB against the opening of the FPCB through-hole. The end of the FPCB close to the FPCB through-hole is bent and deformed to adapt to the shape of the upper plate and / or the lower plate. However, due to the flexibility of the FPCB, the signal transmission function of the FPCB can still operate normally even if it is greatly bent and deformed. At the same time, the microphone bracket can seal the FPCB through-hole.

[0044] For example, in this embodiment, the upper plate 411 and the lower plate 412 are both disc-shaped, and the diameters of the upper plate 411 and the lower plate 412 are both larger than the diameter of the inner hole of the middle connecting ring 1 .

[0045] like Figure 4As shown, the diameter of the lower plate 412 is larger than the diameter of the upper plate 411. When the edge of the lower plate 412 is tightly fitted with the lower end face of the middle connecting ring 1, the lower plate 412 tightly closes the FPCB through hole 10, and the FPCB9 is squeezed and bent by the lower plate 412 and extends to the space below the middle connecting ring 1, effectively sealing and sound insulation. Based on the soft characteristics of the FPCB9, the clamping seat 41 can significantly bend the FPCB9 that penetrates under the middle connecting ring 1, thereby achieving efficient sealing of the FPCB through hole 10. At the same time, the FPCB9 is thin in thickness and highly deformable, and will not cause a large gap between the clamping seat 41 and the middle connecting ring 1, so that the inner hole of the clamping seat 41 and the middle connecting ring 1 further fits.

[0046] In one embodiment, Figure 1 As shown, the FPCB9 is bonded to the side wall of the connecting column 6. The FPCB9 is attached to the side wall of the connecting column 6 by gluing, which can be easily achieved by operators or special jigs, which is conducive to improving the rapid installation of the signal transmission structure.

[0047] In one embodiment, the side wall of the connecting column 6 is provided with a plane, and the FPCB 9 can be directly adhered to the plane of the side wall of the connecting column 6, thereby reducing the space occupied by the FPCB 9 and weakening the spatial impact of the FPCB 9 on the pickup cavity.

[0048] In one embodiment, a groove that matches the shape of the FPCB9 is provided on the side wall plane of the connecting column 6, the bottom wall of the groove is coated with glue, the FPCB9 is bonded in the groove, the thickness of the groove is the same as the thickness of the FPCB9, and the groove is connected to the FPCB through hole 10; the FPCB9 is installed in an embedded structure, which can achieve the maximum structural optimization effect and further prevent the FPCB from affecting the efficiency of sound wave transmission in the pickup cavity.

[0049] In one embodiment, Figure 3 As shown, a PCB mounting plate 12 for mounting the PCB control board 8 is provided on the bottom connecting frame 3 .

[0050] Specifically, the bottom connecting frame 3 includes a base, two support columns and a PCB mounting plate 12. The base is connected to the middle connecting ring 1 through the two support columns, and the base and the middle connecting ring are parallel to each other. The PCB mounting plate 12 is arranged between the two support columns, and the PCB control board 8 is installed on the PCB mounting plate 12. This not only facilitates the assembly of the PCB control board 8, but also facilitates the connection between the FPCB 9 and the PCB control board 8, and can make the PCB control board 8 have a shock-resistant effect.

[0051] In one embodiment, Figure 1-3As shown, there are two connecting columns 6, which are symmetrically distributed on both sides of the middle connecting ring 1. The two connecting columns 6 serve as the overall support of the top cover connecting ring, the top cover and the control unit, effectively realizing the force distribution of the top cover connecting ring, and preventing the top cover connecting ring and / or a single set of connecting columns from being deformed due to uneven force, thereby improving the structural strength of the electrical connection mechanism.

[0052] In one embodiment, Figure 5 As shown, the bottom connecting frame 3 has a reserved battery cavities 13 for accommodating batteries, facilitating later battery installation. Furthermore, the batteries are isolated from the bottom connecting frame 3 and the PCB mounted thereon, effectively preventing heat generated by the batteries during operation from being directly transferred to the bottom connecting frame 3 and PCB via heat transfer, thereby reducing the impact of battery heat on the PCB and the bottom connecting frame.

[0053] In one embodiment, Figure 5 As shown, the central connecting ring 1 is provided with reinforcing ribs 14 on one side near the bottom connecting frame 3. The use of reinforcing ribs helps to improve the structural strength of the central connecting ring and effectively prevents deformation of the central connecting ring. The number of reinforcing ribs is multiple, and the multiple groups of reinforcing ribs are staggered. This helps to eliminate the internal stress generated by the central connecting ring after being subjected to force, prevent the central connecting ring from accidentally deforming, and improve the stability of the entire electrical connection structure.

[0054] Specifically, a plurality of reinforcing ribs 14 are evenly distributed on the bottom surface of the middle connecting ring 1 to improve the structural strength of the middle connecting ring 1 .

[0055] In a second aspect, the utility model discloses a microphone, comprising the above-mentioned electrical connection mechanism.

[0056] The utility model connects the top cover connecting ring and the middle connecting ring through the connecting column to form a sound pickup cavity, and directly adheres the FPCB to the side wall of the connecting column, thereby reducing the space occupied by the FPCB and weakening the spatial impact of the FPCB on the sound pickup cavity, improving the installation efficiency while ensuring the signal transmission efficiency, and solving the technical problem in the prior art that the transmission wire has a certain volume and is directly suspended in the sound pickup cavity, which will have a certain interference effect on the sound pickup effect and is not conducive to the stable presentation of the sound pickup effect; and the FPCB through-hole is tightly covered by the clamping seat of the microphone bracket, effectively ensuring the sealing of the sound pickup cavity, having the effect of sound insulation and noise reduction, and solving the problem that the perforated structure of the transmission wire will cause the sound pickup cavity to be affected by mechanical noise from the outside or the control mechanism.

[0057] It should be noted that the above-mentioned technical features are further combined with each other to form various embodiments not listed above, which are all deemed to be within the scope of the description of the present utility model; and, for ordinary technicians in this field, they can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the present utility model.
