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

[0003] For a traditional wireless microphone, a relatively large battery structure needs to be installed in the reserved space inside. Therefore, the bracket of the wireless microphone generally includes a middle-layer substrate, a top cover bracket and a bottom bracket. The top cover bracket and the bottom bracket are distributed on both sides of the middle-layer substrate. The inner cavity formed by the top cover bracket is used to install a sound pickup microphone head, and the inner cavity of the bottom bracket is used to install a battery and control hardware.

[0004] The microphone brackets in the prior art are designed with a split structure to achieve modularization of the microphone structure and facilitate control of production costs, such as CN209545805U and CN215420655U; however, for the microphones with this structure, multiple component assemblies are required during the production process. For example, the assembly of the bottom bracket and the middle-layer substrate, and the assembly of the top cover bracket and the middle-layer substrate. The assembly steps are numerous and time-consuming, and at the same time, there is a certain defective rate for each assembly step, and the accumulation of multiple defective rates leads to a decrease in the overall microphone assembly efficiency.

[0005] The prior art has defects and needs to be improved. Summary of the Utility Model

[0006] In order to solve the defect existing in the current technology that the internal bracket structure of the microphone is designed with a split assembly, resulting in a decrease in the assembly speed and the assembly yield rate of the microphone, the utility model provides a quick-release mounting bracket and a microphone thereof.

[0007] The technical solution provided by the utility model, a quick-release mounting bracket, includes a top cover bracket, a middle-layer substrate and a bottom bracket. The top cover bracket, the middle-layer substrate and the bottom bracket are integrally injection-molded. A control circuit board is fixed on the top cover bracket.

Screw holes are arranged on the bottom bracket for locking the lower shell.

[0010] Preferably, both the upper connecting columns and the lower connecting columns are provided with two, and the two upper connecting columns and the two lower connecting columns are symmetrically arranged on both sides of the central axis of the quick-release mounting bracket.

[0011] Preferably, the electronic control unit includes a power supply and a PCB main board. Fixing holes for the PCB main board are arranged on one side of the PCB mounting board, and symmetric clamping claws are arranged on the other side of the PCB mounting board for clamping the power supply.

Detailed Description of the Preferred Embodiment

[0022] 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 described 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.

[0023] For the convenience of understanding the present utility model, the present utility model will be described in more detail below with reference to the drawings and specific embodiments. The preferred embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are only for the purpose of illustration.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not used to limit this utility model.

[0026] The following provides a detailed description of this utility model in conjunction with the accompanying drawings.

[0027] As Figure 1 and Figure 2 shown, a quick-release mounting bracket includes a top cover bracket 1, a middle layer substrate 2 and a bottom bracket 3. The top cover bracket 1, the middle layer substrate 2 and the bottom bracket 3 are integrally formed by injection molding. A control circuit board 9 is fixed on the top cover bracket 1. There is a sound pickup cavity between the top cover bracket 1 and the middle layer substrate 2, and a microphone assembly 10 is fixed in the sound pickup cavity. An electronic control unit is installed between the middle layer substrate 2 and the bottom bracket 3. The layered setting prevents electromagnetic interference between the microphone assembly and circuit components.

[0028] By setting the top cover bracket 1, the middle layer substrate 2 and the bottom bracket 3 of the quick-release mounting bracket to be integrally formed by injection molding, in this way, compared with the split assembly design of the prior art, the assembly steps of the bracket itself can be omitted, and the assembly efficiency of the microphone can be improved.

[0029] It should be particularly noted that the middle layer substrate 2 divides the quick-release mounting bracket into upper and lower spaces. The upper space is the sound pickup cavity for fixing the microphone assembly 10. The microphone assembly 10 includes a microphone mounting frame 13 and a microphone 14. The microphone 14 is electrically connected to the PCB main board 12 and is fixed in the microphone mounting frame 13 by being clamped. The lower space is used to install the power supply 11. The power supply 11 is connected to the PCB main board 12. The power supply 11 is a lithium battery or other rechargeable battery. The lithium battery supplies power to the microphone, or an external power supply charges the lithium battery through the PCB main board 12. In this way, on-demand power supply is realized. When the microphone is running, if there is a lack of external power supply, the lithium battery supplies power. If there is an external power supply, the external power supply not only charges the lithium battery but also supplies power to the circuit board. When the microphone is in a non-operating state, the external power supply only charges the lithium battery. In this way, multiple usage scenarios of the microphone are realized.

[0030] Preferably, the top cover bracket 1 and the middle layer substrate 2 are integrally formed through an upper connecting column 4, the middle layer substrate 2 and the bottom bracket 3 are integrally formed through a lower connecting column 5, a PCB mounting board 6 is arranged on the lower connecting column 5, and the electronic control unit is fixed on the PCB mounting board 6. In this way, the upper connecting column 4 and the lower connecting column 5 constitute an important structure of the quick-release mounting bracket formed integrally, and at the same time, it does not affect the installation of the electronic control unit inside the microphone.

[0031] It should be particularly noted that the PCB mounting board 6 vertically divides the lower space into two parts. One side fixes the lithium battery, and the other side locks the PCB main board 12 with screws. The PCB mounting board 6 can be locked to the lower connecting column 5 with screws. Preferably, the PCB mounting board 6 and the lower connecting column 5 are integrally injection-molded. In this way, not only can the assembly steps of the microphone be reduced, but also the overall stability can be increased.

[0032] Preferably, both the top cover bracket 1 and the middle layer substrate 2 are annular. The annular hole of the top cover bracket 1 provides a clearance position for the control circuit board 9. The microphone assembly 10 passes through the annular hole of the middle layer substrate 2 and is fixed on the middle layer substrate 2. Screw holes are provided on the upper part of the bottom bracket 3 for locking the lower shell 18. The annular top cover bracket 1 can not only fix the control circuit board 9, but also provide a clearance position for the control circuit board, so that there is a position for the electrical components on the control circuit board, and at the same time, it can pass through the flexible circuit board 15.

[0033] It should be particularly noted that the shape of the annular hole of the top cover bracket 1 can be circular, square, or irregular, matching the shape of the control circuit board 9. The shape of the annular hole is not limited here. A stepped groove is arranged above the top cover bracket 1. The control circuit board 9 is placed in the stepped groove above the top cover bracket 1 and the control circuit board 9 is locked with screws. In this way, through the design of the stepped groove, the positioning installation of the control circuit board 9 can be realized, preventing the control circuit board 9 from shifting during installation and improving the installation accuracy.

[0034] A stepped groove is arranged at the edge of the annular hole of the middle layer substrate 2. The bottom of the microphone mounting bracket 13 of the microphone assembly 10 is embedded into the stepped groove of the middle layer substrate 2 from bottom to top and is locked with screws. Further, reinforcing ribs are arranged on the middle layer substrate 2 to increase the stability of the middle layer substrate 2. As a key position connecting the top cover bracket 1 and the bottom bracket 3, the strength of the middle layer substrate 2 affects the stability of the overall quick-release mounting bracket.

[0035] Both the upper connecting column 4 and the lower connecting column 5 can be set to one, which plays a role in connecting the top cover bracket 1 and the bottom bracket 3, making the quick-release mounting bracket form an integral body and reducing the assembly steps.

[0036] Preferably, both the upper connecting column 4 and the lower connecting column 5 are provided in two numbers, and the two upper connecting columns 4 and the two lower connecting columns 5 are symmetrically arranged on both sides of the central axis of the quick-release mounting bracket. In this way, the two upper connecting columns 4 and the two lower connecting columns 5 can increase the stability of the quick-release mounting bracket. Of course, the number of the upper connecting column 4 and the lower connecting column 5 can also be increased as needed. The number of the upper connecting column 4 and the lower connecting column 5 can be set to multiple, for example, the upper connecting column 4 is set to three and evenly arranged on the outer periphery of the top cover bracket 1 and the middle layer substrate 2, and the lower connecting column 5 is set to three and evenly arranged on the outer periphery of the base 19 bracket and the middle layer substrate 2, as long as it does not affect the assembly of other components of the microphone.

[0037] It should be particularly noted that both the upper connecting column 4 and the lower connecting column are set to be flat columns, which can ensure the stability of the quick-release mounting bracket while providing more installation space inside.

[0038] Preferably, on one side of the PCB mounting plate 6, fixing holes for the PCB main board 12 are provided, and on the other side of the PCB mounting plate 6, symmetric claws 7 are provided. The claws 7 are used to hold the power supply 11. In this way, the claws 7 provided on the PCB mounting plate can install the lithium battery on the quick-release mounting bracket together when assembling the microphone. The structure of the claws 7 is more convenient than the way of screw locking or hot melt adhesive fixing.

[0039] It should be particularly noted that, further, positioning pins are provided on the PCB mounting plate 6, and corresponding positioning holes are provided on the PCB main board 12, so that the quick positioning and installation of the PCB main board 12 can be realized. The fixing holes of the PCB main board 12 are provided in four numbers and are arranged around the PCB mounting plate 6.

[0040] Preferably, a through hole 8 is provided on the middle layer substrate 2. The through hole 8 is provided inside and close to the upper connecting column 4. The through hole 8 is used for passing the flexible circuit board 15. The flexible circuit board 15 is used to connect the PCB main board 12 and the control circuit board 9, and the flexible circuit board 15 is attached to the inner side wall of the upper connecting column 4. The flexible circuit board 15 realizes convenient fitting and installation while reducing the space occupation ratio, reducing the interference of sound collection, and making the internal wiring more regular.

[0041] It should be particularly noted that the upper connecting column 4 is set to be a flat column, and the flexible circuit board 15 is attached to the inner side wall of the upper connecting column 4, which can be better fixed. The shape of the through hole 8 is adapted to the shape of the flexible circuit board 15. For example, the through hole 8 is set to be arc-shaped.

[0042] In a preferred embodiment, the spacing between the two upper connecting posts 4 is smaller than the spacing between the two lower connecting posts 5, and the integrated steel mesh 16 is sleeved around the outer periphery of the two upper connecting posts 4, covering the sound pickup cavity. The use of closely spaced upper connecting posts 5 facilitates providing an adequate installation environment for the integrated steel mesh 16. Furthermore, the outer diameter of the top cover bracket 1 is smaller than the inner diameter of the integrated steel mesh 16. Combined with the closely spaced design of the upper connecting posts 5, the integrated steel mesh 16 can be moved along the direction of the upper connecting posts 5 to cover the entire sound pickup cavity during installation, further enhancing installation convenience.

[0043] It should be noted that the distance between the two upper connecting columns 4 is smaller than the distance between the two lower connecting columns, so that the diameter of the upper space and the lower space after being covered with the integrated steel mesh 16 are the same, and the main body of the microphone presents a columnar shape with the same diameter.

[0044] Furthermore, a sponge is provided between the integrated steel mesh 16 and the quick-release mounting bracket. The integrated steel mesh 16 is provided in a cylindrical shape, with notches provided on the circumference of the top and bottom. Corresponding protrusions are provided on the middle substrate 2, which match the bottom notches of the integrated steel mesh 16. A top cover 17 is provided on the top cover bracket 1, and the top cover 17 is also provided with a protrusion that matches the top notch of the integrated steel mesh 16. The top cover 17 is screwed to the top cover bracket 1, and the control circuit board 9 is also screwed thereto. In this way, not only the positioning and installation of the integrated steel mesh 16 is achieved, but also the top cover 17 and the control circuit board 9 can be locked at once, reducing the assembly steps and increasing convenience.

[0045] like Figure 2 and Figure 3 As shown, a microphone includes a quick-release mounting bracket, a microphone assembly 10, a power supply 11, a PCB mainboard 12, a control circuit board 9, a flexible circuit board 15, an integrated steel mesh 16, a top cover 17 and a lower shell 18. The microphone assembly 10, the power supply 11, the PCB mainboard 12, the control circuit board 9, and the flexible circuit board 15 are all fixed in the quick-release mounting bracket. The integrated steel mesh 16 is sleeved on the outside of the upper part of the quick-release mounting bracket and locked by the top cover 17. The lower shell 18 is sleeved on the outside of the lower part of the quick-release mounting bracket and is locked to the bottom bracket 3 by screws.

[0046] It should be noted that the bottom of the lower housing 18 has a clearance hole for passing an external connector soldered to the PCB 12. A circular hole is also provided on the side wall of the lower housing 18 for passing a knob soldered to the PCB 12. The external connector is located at the bottom of the microphone to avoid cluttering the wiring harness and prevent it from being knocked off.

[0047] In a preferred embodiment, the microphone is snap - connected to the support base. The support base includes a base 19, a vertical arm 20, a rotating shaft 21, and a snap - ring 22. The vertical arm 20 is fixed to the base 19. The top end of the vertical arm 20 is connected to the snap - ring 22 through the rotating shaft 21, and the microphone is snap - connected within the snap - ring 22.

[0048] It should be specifically noted that multiple slots are provided on the inner ring of the snap - ring 22, and elastic ropes are arranged on the slots. The elastic ropes are tightly connected to the lower housing 18 of the microphone to achieve the fixation of the microphone. Preferably, four slots are provided and are evenly distributed on the inner circumference of the snap - ring 22. The pitching angle of the microphone can be adjusted by loosening the rotating shaft 21 of the microphone, and then the rotating shaft 21 is locked for fixation.

[0049] In a preferred embodiment, a spray - proof net 23 is vertically arranged on the snap - ring 22, and the spray - proof net 23 is used to prevent the user from spraying the microphone.

[0050] It should be specifically noted that a ring groove is provided on one side of the snap - ring 22 relative to the rotating shaft 21. A clamping member is provided at the bottom of the spray - proof net 23, and the clamping member cooperates with the ring groove to achieve the snap - connection of the spray - proof net 23. The spray - proof net 23 is arranged in an arc shape, and the arc of the spray - proof net 23 in the clamped position is the same, maintaining the consistency of the arc as a whole.

[0051] During the assembly of the microphone, first place the top cover 17 upside - down on the installation operation surface, then set the quick - release mounting bracket upside - down so that the top - cover bracket 1 is aligned with the top cover 17 downward, and then lock the top - cover bracket 1 and the top cover 17; the PCB main board 12 can be installed on the PCB mounting board 6 before or after locking;

[0052] Then, the integrated steel mesh passes through the bottom bracket, the middle substrate, and the top - cover bracket in sequence along the length direction of the mounting bracket until it is positioned and snap - connected to the limit slot on the top cover, that is, covering the entire sound - pickup cavity, sleeving the lower housing 18, and locking it with screws, and is integrally snap - connected to the snap - ring 22 of the support base. In the prior art, when installing the microphone from the lower housing to the top cover and finally locking the top cover, in order to cover the screw holes on the top, a decorative plate needs to be added. The inverted installation method of this application, compared with the prior art, reduces the installation of the decorative plate, reduces the installation steps, saves materials, and also ensures the aesthetics of the microphone.

[0053] It should be noted that the above - mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as within the scope described in the specification of the present utility model; and for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present utility model.
