Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of microphones, and particularly relates to a loading structure for internal components of a microphone. Background Art
[0002] As a sound pickup component, each part of the microphone has different degrees of influence on the sound pickup function.
[0003] The microphone includes a housing, a microphone head, and an electronic control component. The microphone head and the electronic control component are both arranged in the housing. The microphone head is used for receiving sound, and the electronic control component is used for controlling the operation of the microphone head and transmitting electrical signals. Among them, the electronic control component needs to be fixed in the housing through a mounting bracket.
[0004] In the prior art, the mounting bracket has a frame structure. The traditional mounting method is that the top of the mounting bracket is connected to the housing by screws or buckles, and the whole housing wraps the whole mounting bracket.
[0005] However, the mounting bracket in the prior art has the following problems:
[0006] There is a lack of limit in the middle position of the mounting bracket, which is prone to mechanical vibration, thereby affecting the overall sound pickup effect. Moreover, due to connecting different parts on the inner side wall of the traditional housing, such as the edge of the mounting bracket, the knob adjustment button, the connection part between the housing and the bracket, etc., the forces received by different areas of the housing are different. The traditional housing does not specifically adjust the structure for each part of the components. Instead, it more often blindly piles up materials and thickens them to improve the structural strength, thereby dealing with the force problems of all components. On the one hand, blind piling up of materials leads to an increase in cost. On the other hand, the mass of the whole housing increases, which affects the consumer's hand feeling and also causes a greater burden on the microphone bracket, making it easy to fall from the microphone bracket. Summary of the Utility Model
[0007] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a loading structure for internal components of a microphone to solve the problems raised in the above background art. To achieve the above purpose, the following technical solutions are adopted in the utility model:
[0008] The loading structure for internal components of the microphone includes a housing and a mounting bracket detachably connected to the housing. An installation cavity is arranged in the housing;
[0009] The mounting bracket includes:
[0010] A substrate detachably arranged at one end of the installation cavity;
[0011] A bottom mounting frame arranged on one side of the substrate and clamped with the inner wall of the installation cavity for installing electronic control components;
[0012] The top mounting frame is arranged on the other side of the substrate and located outside the housing for mounting the microphone head.
[0013] Optionally, two limiting card slots are symmetrically arranged on the inner wall of the mounting cavity, and the bottom mounting frame is respectively clamped with the two limiting card slots.
[0014] Optionally, mounting posts are respectively arranged on both sides of the bottom mounting frame, and the two mounting posts respectively correspond to and are clamped with the two limiting card slots one by one.
[0015] Optionally, a plurality of threaded groove columns are equally spaced along the circumferential side of the inner wall of the mounting cavity.
[0016] Optionally, the substrate is respectively threadedly connected with the plurality of threaded groove columns.
[0017] Optionally, a plurality of reinforcing ribs are arranged at intervals along the axial direction of the inner wall of the mounting cavity.
[0018] Optionally, a counterbore is arranged at the end of the inner wall of the mounting cavity.
[0019] Optionally, the substrate abuts against the counterbore.
[0020] Optionally, thickened areas are arranged at the positions of the inner wall of the mounting cavity corresponding to the two limiting card slots.
[0021] Optionally, each limiting card slot is composed of two convex ribs arranged at intervals.
[0022] The beneficial effect compared with the prior art is that with the above scheme, in the present utility model, a bottom mounting frame is arranged on one side of the substrate and a top mounting frame is arranged on the other side to respectively fix the microphone head and the electronic control components, and the bottom mounting frame is limited and fixed by clamping the bottom mounting frame with the inner wall of the mounting cavity. By detachably mounting the substrate on the top of the mounting cavity, the whole mounting bracket is fixed, effectively reducing the pickup interference caused by the mechanical vibration of the mounting bracket;
[0023] By designing the limiting card slot structure, when assembling the mounting bracket, it only needs to push the mounting post along the length direction of the limiting card slot, reducing the installation difficulty;
[0024] By enabling the screws on the bottom plate and the substrate to be locked on the same threaded groove column, the positioning effect is effectively improved, and it is beneficial to concentrate the acting force generated by locking the screws on the protruding threaded groove column. The three threaded groove columns are distributed in a triangular shape structure on the inner wall of the housing. On the one hand, the installation stability of the substrate and the bottom plate is effectively improved. On the other hand, the acting force is distributed on the whole housing through the three threaded groove columns, effectively realizing uniform stress on the housing;
[0025] By evenly circumferentially distributing reinforcing ribs, thickened areas, threaded groove columns, and limiting ribs on the inner wall of the installation cavity at a preset interval, and specifically thickening the design for components with relatively large connection masses, such as the positions of the knob and the button, while improving the structural strength of the housing, the production cost is reduced, and the housing quality will not increase, thus not affecting the consumer's hand feeling and the burden on the microphone bracket.

[0036] As Figures 1-3 shown, an embodiment of the present utility model is: the internal component loading structure of the microphone, which includes a housing 1 and a mounting bracket 2 detachably connected to the housing 1. An installation cavity is provided inside the housing 1; the mounting bracket 2 includes: a substrate 3, a bottom mounting frame 4 and a top mounting frame 5. The substrate 3 is detachably arranged at the top end of the installation cavity; the bottom mounting frame 4 is arranged on one side of the bottom end of the substrate 3 and is clamped with the inner wall of the installation cavity for mounting the electronic control component 6; the top mounting frame 5 is arranged on one side of the top end of the substrate 3 and is located outside the housing 1 for mounting the microphone head 7.
[0037] It can be understood that by arranging the bottom mounting frame 4 on one side of the substrate 3 and the top mounting frame 5 on the other side, the microphone head 7 and the electronic control component 6 are respectively fixed. By clamping the bottom mounting frame 4 with the inner wall of the installation cavity, the bottom mounting frame 4 is limited and fixed. By detachably mounting the substrate 3 at the top end of the installation cavity, the whole mounting bracket 2 is fixed, effectively reducing the pickup interference caused by the mechanical vibration of the mounting bracket 2.
[0038] In one embodiment, as Figures 4-5 shown, two limiting slots 8 are symmetrically arranged on the inner wall of the installation cavity, and the bottom mounting frame 4 is respectively clamped with the two limiting slots 8.
[0039] Specifically, a limiting slot 8 is arranged on each of the left and right sides of the inner wall of the installation cavity. The two limiting slots 8 are both distributed along the length direction of the installation cavity. The two sides of the bottom mounting frame 4 respectively correspond to and are clamped with the two limiting slots 8. During assembly, the two sides of the bottom mounting frame 4 are respectively corresponding to the two limiting slots 8, and are pushed along the length direction of the limiting slots 8 to move the bottom frame to a preset position, and then the bottom mounting frame 4 can be fixed.
[0040] In one embodiment, as Figure 3As shown, mounting posts 41 are respectively provided on both sides of the bottom mounting frame 4, and the two mounting posts 41 respectively correspond to and are snap-fitted with the two limit card slots 8; it can be understood that the distance between the outer walls of the two mounting posts 41 is close to the width of the mounting cavity, and the thickness of the mounting post 41 is close to the width of the limit card slot 8. The PCB board 61 of the electronic control component 6 is arranged on the bottom mounting frame 4 between the two mounting posts 41, and the thickness of the mounting post 41 is greater than the thickness of the PCB board 61, so that the PCB board 61 can be protected during installation, disassembly and use.
[0041] In one embodiment, as Figure 2 shown, there are two PCB boards 61, which are respectively detachably arranged on both sides of the bottom mounting frame 4.
[0042] In one embodiment, as Figures 4-5 shown, a plurality of threaded groove columns 9 are equally spaced at intervals on the circumferential side of the inner wall of the mounting cavity.
[0043] In this embodiment, the number of the threaded groove columns 9 is three, and the three threaded groove columns 9 are evenly distributed on the inner wall of the housing 1 around the central axis of the mounting cavity, and the length direction of each threaded groove column 9 is the same as the length direction of the mounting cavity.
[0044] In one embodiment, as Figure 2 、 4 、5 shown, the substrate 3 is respectively threadedly connected with a plurality of the threaded groove columns 9.
[0045] It can be understood that three screw holes are respectively provided on the substrate 3 corresponding to the three threaded groove columns 9, and the substrate 3 is respectively connected to the tops of the three threaded groove columns 9 by three screws.
[0046] In one embodiment, it further includes a bottom plate 10. Openings are provided at both ends of the mounting cavity to facilitate the installation of different electronic control components 6 from different opening directions. The bottom plate 10 is detachably arranged at one end of the housing 1 away from the substrate 3 for covering the opening at one end of the mounting cavity away from the substrate 3.
[0047] In one embodiment, screw holes are respectively provided on the bottom plate 10 corresponding to the three threaded groove columns 9, and the bottom plate 10 is respectively fixed to the bottoms of the threaded groove columns 9 by three screws.
[0048] It can be understood that the length of the threaded groove column 9 is equal to the length of the housing 1. The screws on the bottom plate 10 and the base plate 3 can be locked on the same threaded groove column 9, effectively improving the positioning effect. Moreover, the bottom plate 10 and the base plate 3 are respectively locked on the same threaded groove column 9 by screws, which is beneficial to concentrating the acting force generated by the screw locking on the protruding threaded groove column 9. On the one hand, the installation stability of the base plate 3 and the bottom plate 10 is effectively improved. On the other hand, the acting force is distributed on the entire housing 1 through the three groups of threaded groove columns 9, effectively achieving uniform stress on the housing 1.
[0049] In one embodiment, as Figure 2 shown, it further includes an upper shell 11, and the upper shell 11 is sleeved on one end of the housing 1 away from the bottom plate 10.
[0050] In one embodiment, as Figures 4-5 shown, a plurality of reinforcing ribs 12 are arranged at intervals along the axial direction of the inner wall of the installation cavity to improve the structural strength of the housing 1.
[0051] In one embodiment, as Figure 4 shown, a counterbore 13 is provided at the end of the inner wall of the installation cavity.
[0052] Specifically, the lengths of the reinforcing ribs 12, the threaded groove columns 9, and the limit card slots 8 are all equal and slightly less than the length of the housing 1. The ends of the reinforcing ribs 12, the threaded groove columns 9, and the limit card slots 8 are respectively in the same plane as the counterbore 13.
[0053] In one embodiment, as Figures 3-4 shown, the base plate 3 abuts against the counterbore 13 at the top of the installation cavity to limit the base plate 3 during installation. After the base plate 3 is fixed, the whole base plate 3 is located in the installation cavity. It can be understood that the bottom counterbore 13 is used to abut against the bottom plate 10, so that the bottom surface of the bottom plate 10 and the bottom end surface of the installation cavity are in the same plane, protecting the base plate 3 and the bottom plate 10 while improving the overall integration of the exterior of the microphone.
[0054] In one embodiment, as Figures 4-5 shown, thickened areas 14 are provided at the positions of the inner wall of the installation cavity corresponding to the two limit card slots 8.
[0055] Specifically, the inner wall of the installation cavity where the two limit card slots 8 are located is designed with thickening to improve the structural strength of the housing 1.
[0056] In one embodiment, as Figure 4 shown, each limit card slot 8 is composed of two spaced convex ribs 81, and both of the two limit convex ribs 81 are located on the thickened area 14 to improve the structural strength of the limit card slot 8.
[0057] In one embodiment, as Figure 5As shown, the reinforcing ribs 12, thickening areas 14, threaded groove columns 9 and limiting convex ribs 81 are evenly circumferentially distributed on the inner wall of the installation cavity at preset intervals, and thickening design is specifically carried out for the components with larger connection mass, such as the positions of the knob and the button. While improving the structural strength of the housing 1, the production cost is reduced, and the quality of the housing will not increase, which will not affect the consumer's hand feeling and the burden on the microphone bracket.
[0058] In this application, a bottom mounting frame 4 is arranged on one side of the substrate 3, and a top mounting frame 5 is arranged on the other side. The microphone 7 and the electronic control component 6 are respectively fixed. By clamping the bottom mounting frame 4 with the inner wall of the installation cavity, the bottom mounting frame 4 is limited and fixed. By detachably mounting the substrate 3 at the top of the installation cavity, the whole mounting bracket 2 is fixed, effectively reducing the pickup interference caused by the mechanical vibration of the mounting bracket 2.
[0059] By designing the structure of the limiting card slot 8, when assembling the mounting bracket 2, it is only necessary to push the mounting column 41 along the length direction of the limiting card slot 8, reducing the installation difficulty.
[0060] By enabling the screws on the bottom plate 10 and the substrate 3 to be locked on the same threaded groove column 9, the positioning effect is effectively improved, and it is beneficial to concentrate the acting force generated by the screw locking on the protruding threaded groove column 9. The three threaded groove columns 9 are distributed in a triangular structure on the inner wall of the housing 1. On the one hand, the installation stability of the substrate 3 and the bottom plate 10 is effectively improved. On the other hand, the acting force is distributed on the whole housing 1 through the three threaded groove columns 9, effectively realizing uniform stress of the housing 1.
[0061] By setting the thickening area 14, while improving the structural strength of the housing 1, the production cost is controlled, effectively improving the market value of the microphone.
[0062] It should be noted that the above technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as the scope recorded in the description of the present utility model; and for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all these improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
