Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically a fixing structure for microphone windproof cotton. Background Technology

[0002] When microphones are used outdoors or in environments with strong airflow, the direct impact of airflow on the diaphragm will generate significant wind noise. Polyurethane foam is commonly used to suppress this noise.

[0003] The existing fixing method is mainly to directly attach the microphone, relying on the elasticity of the foam to hold the microphone head. Although the operation is simple, after repeated insertion and removal or the influence of lateral wind and shaking, the windproof cotton is prone to loosening, rotating or even falling off, resulting in the failure of protection. Users need to make frequent adjustments, which affects continuous recording.

[0004] To improve the securing effect, some solutions use rubber bands, Velcro straps, or metal clamps for binding. While this increases clamping force, it adds installation steps, and exposed binding parts are prone to snagging clothing and cables. Furthermore, rubber bands are prone to aging and breakage, and Velcro straps shed fibers, causing secondary pollution and increased maintenance costs. Another option is a rigid buckle structure, using plastic clips or metal springs for clamping. While this provides strong clamping force, the numerous parts and thick walls significantly increase the head weight, altering the microphone's center of gravity and placing additional strain on the support. Repeated opening and closing can cause stress concentration points to break, requiring complete replacement and shortening the lifespan. A small number of products use an adhesive-bonded, threaded base, where the bottom of the windproof cotton is glued to the base and then screwed onto the microphone shell via internal threads. While this prevents detachment, the threads must correspond precisely to the microphone diameter, requiring high tolerances and resulting in poor compatibility. Additionally, the adhesive is prone to aging and peeling in damp or low-temperature conditions, and residual adhesive is difficult to clean after disassembly, hindering reuse.

[0005] In summary, existing technologies cannot simultaneously meet the requirements of quick assembly and disassembly, secure and non-loosening, lightweight, universal compatibility, and long lifespan, and urgently need improvement. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fixing structure for microphone windproof cotton, which can stably install the microphone windproof cotton on the microphone and can achieve quick assembly and disassembly.

[0007] To achieve the above objectives, a microphone windproof cotton fixing structure is designed for a microphone with a radial protrusion in the middle, comprising: a fixing base with a through opening for the microphone to pass through, an enclosure structure along the through opening, a horizontal extension on the outer periphery of the enclosure structure, a fixing groove on the upper surface of the horizontal extension, and notches on both sides of the enclosure structure; a quick-release buckle, which has a Z-shaped bending structure and is integrally formed with the fixing base at the notch, including a release handle and a buckle claw, forming a lever system with the release handle as the power arm and the buckle claw as the resistance arm, with the connection point with the fixing base as the fulcrum; the buckle claw includes a downwardly extending elastic arm and a claw at the end of the elastic arm, the claw having a limiting locking platform for engaging or releasing the radial protrusion; and a windproof cotton body having a hollow inner cavity to accommodate the microphone, with the end of the windproof cotton body disposed in the fixing groove.

[0008] Preferably, the present invention further includes: the upper end of the fixing base is provided with an inwardly extending step structure, the lower surface of the step structure abutting against the upper surface of the radial protrusion, so as to restrict the fixing base from moving downward.

[0009] Preferably, the present invention further includes: the fixing base is provided with an avoidance through hole on the outer side of the connection with the quick release buckle, for providing space for the elastic deformation of the quick release buckle.

[0010] Preferably, the present invention further includes: a sinking groove is provided at the lower part of the windproof cotton body, the release handle is engaged in the sinking groove, and the outer side of the release handle abuts against the inner side of the sinking groove.

[0011] Preferably, the present invention further includes: the length of the release handle is greater than the length of the buckle claw, so that the lever system constitutes a force-saving lever.

[0012] Preferably, the present invention further includes: the fixed base is provided with several shock-absorbing structures, including: two notches opened side by side on the upper edge of the fixed base, and a cantilever rack formed between the two notches; an elastic shock-absorbing ring, sleeved on the cantilever rack; the elastic shock-absorbing ring is compressed between the windproof cotton body and the fixed base, and between the fixed base and the microphone, for absorbing rigid vibration.

[0013] Preferably, the present invention further includes: a guide slope is provided at the lower end of the hook, and during the process of the fixed seat sleeve moving towards the microphone, the guide slope slides in contact with the radial protrusion to form a friction pair with low friction force.

[0014] Preferably, the present invention further includes: the lower end of the release handle is provided with an inwardly bent portion, the release handle is connected to the buckle claw through the bent portion, and the bent portion and the buckle claw are arranged radially offset to form a lever system with a longer power arm.

[0015] Preferably, the present invention further includes: in the locked state, the upper surface of the limiting plate abuts against the lower surface of the radial protrusion to restrict the fixing seat from coming off upward; in the disassembled state, pressing the release handle causes the hook to open outward, thereby releasing the engagement with the radial protrusion.

[0016] Preferably, the present invention further includes: a first wedge-shaped reinforcing rib provided on the inner side of the release handle, and a second wedge-shaped reinforcing rib provided on the outer side of the buckle claw, for improving the rigidity of the quick release buckle.

[0017] Compared with the prior art, the advantages of this utility model are: This invention utilizes a lever mechanism between a fixed base and a quick-release buckle to allow the windproof cotton body to be quickly locked or released on the microphone with a single hand press, eliminating the need for rotation or binding and avoiding additional tools, thus improving operational efficiency in continuous recording scenarios. When locked, the limiting plate and radial protrusion abut against each other vertically, while the stepped structure simultaneously restricts downward movement, forming a bidirectional limiting effect. Even under lateral wind force or severe microphone shaking, the fixed base remains in place, preventing loosening, rotation, and detachment. The windproof position is always aligned with the diaphragm center, ensuring stable and consistent wind noise suppression. The shock-absorbing ring is compressed between the windproof cotton, the fixed base, and the microphone, converting rigid vibrations such as hand friction and low-frequency impacts into elastic micro-displacement, significantly reducing noise transmission and improving recording purity. The guiding slope minimizes resistance during installation; the avoidance through-hole provides space for the buckle's elastic deformation, ensuring that the stress on the elastic arm remains below the material's yield limit after tens of thousands of openings and closings, extending service life. The release handle is hidden within a recessed groove, with a smooth transition between its outer side and the windproof cotton outline, resulting in a clean appearance and preventing accidental contact. With fewer overall parts and a one-piece injection-molded mounting base, the microphone's center of gravity remains almost unchanged, and its impact on the cantilever bracket's load is negligible. The bottom of the windproof cotton is glued or press-fitted into the mounting slot, allowing for repeated replacement. Residual adhesive is only present at the bottom of the slot, minimizing cleaning area and facilitating maintenance. These features collectively address the problems of slow assembly / disassembly, easy loosening, short lifespan, and poor compatibility in existing technologies, achieving a comprehensive performance improvement in terms of speed, stability, lightweight design, and long lifespan.

[0019] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0020] This utility model's microphone windproof cotton fixing structure is suitable for microphones 11 with radial protrusions 12 in the middle, such as... Figures 1 to 9 As shown, it mainly includes a fixing base 30, a quick-release buckle 41, and a windproof cotton body 21. The components work together to achieve stable installation and quick disassembly of the windproof cotton. The specific structure and assembly relationship are as follows: The direction facing the microphone 11 is the inside, and the direction away from the microphone 11 is the outside.

[0021] The mounting base 30, as the core load-bearing component, is made of special plastic through one-piece injection molding, which not only ensures structural strength but also effectively controls the overall weight, hardly changes the original center of gravity of the microphone, and has a negligible impact on the load of the cantilever bracket.

[0022] The mounting base 30 has a through opening 32, the size of which is adapted to the outer diameter of the radial protrusion 12 of the microphone 11, allowing the microphone 11 to pass through smoothly and ensuring a good fit. A surrounding structure 31 is provided along the through opening 32, arranged in a ring shape, which can wrap around the outer periphery of the radial protrusion 12 of the microphone 11 to a certain extent, improving the stability after assembly. A horizontal extension 35 is provided on the outer periphery of the surrounding structure 31, and a fixing groove 36 is formed on the upper surface of the horizontal extension 35. The shape of the fixing groove 36 matches the end of the windproof cotton body 21, used to accommodate and fix the bottom of the windproof cotton body 21. The bottom of the windproof cotton body 21 can be connected to the fixing groove 36 by special adhesive bonding or interference fit. Adhesion ensures reliable connection, while interference fit facilitates subsequent replacement of the windproof cotton body 21, and residual adhesive only exists at the bottom of the fixing groove 36, resulting in a small cleaning area and convenient maintenance.

[0023] The enclosure structure 31 has symmetrical buckle mounting notches 37 on both sides. The quick release buckle 41 is set at the notch 37 of the enclosure structure and is integrally injection molded with the fixing seat 30, which reduces the number of parts, simplifies the assembly process, and improves the integrity and durability of the structure.

[0024] The quick-release buckle 41 has a Z-shaped bending structure, including a release handle 42 and a buckle claw 45. With the connection point 41 with the fixed base 30 as the fulcrum, it forms a lever system where the release handle 42 is the power arm and the buckle claw 45 is the resistance arm. To achieve effortless operation, the length of the release handle 42 is greater than the length of the buckle claw 45, making the lever system a force-saving lever, allowing the user to complete locking or releasing actions with relatively small pressing force. The lower end of the release handle 42 has an inwardly bent portion 43, through which the release handle 42 connects to the buckle claw 45. The bent portion 43 and the buckle claw 45 are radially offset, further extending the power arm length and optimizing the force-saving effect of the lever, ensuring easy one-handed operation. The lower end of the release handle 42 has an integrally formed inwardly bent portion 43, which causes the release handle 42 and the buckle claw 45 to form a preset angle in the radial direction, rather than a straight connection. Compared to the straight release handle structure without bends, in this structure, the connection 41 between the quick release buckle 41 and the fixed base 30 is used as the fulcrum. The length of the power arm from the point of force application of the release handle 42 to the fulcrum is changed from the single line segment length of the traditional straight release handle to a zigzag path length formed by the release handle 42 segment and the bend 43 segment. That is, this zigzag path can be equivalently regarded as the length of the hypotenuse corresponding to the point of force application of the release handle 42 in a triangular structure with the fulcrum (connection 41), the point of force application of the release handle 42, and the connection point between the bend 43 and the buckle claw 45 as vertices. By utilizing the angled design formed by the bending portion 43, the actual working length of the power arm is effectively extended without increasing the overall radial dimension of the fixed base 30. This makes the lever system consisting of the release handle 42, the latch 45, and the connection 41 more effective in saving effort. Users only need to apply a small amount of pressure to drive the elastic arm 46 of the latch 45 to undergo elastic deformation, thereby releasing the limiting plate 48 of the latch 47 from the radial protrusion 12 of the microphone 11. This further optimizes the ease of disassembly and assembly of the windproof cotton body 21. At the same time, the recessed groove 23 at the bottom of the windproof cotton body 21 conceals the release handle 42, avoiding accidental contact caused by the outward protrusion of the bending portion 43 and the release handle 42, and ensuring the neatness of the overall structural appearance.

[0025] Preferably, the outer wall of the release handle 42 can be connected to the windproof cotton body 21 by means of glue or ultrasonic welding, so that the windproof cotton body 21 and the fixing seat 30 are fixed as an integral structure, and the integral structure of the windproof cotton body 21 and the fixing seat 30 and the microphone 11 are detachable assembly structures.

[0026] The latching claw 45 includes a downwardly extending elastic arm 46 and a claw 47 located at the end of the elastic arm 46. The top of the claw 47 is provided with a limiting plate 48 that is adapted to the radial protrusion 12 of the microphone 11, for engaging or releasing with the lower edge of the radial protrusion 12. The lower end of the claw 47 is provided with a guide slope. During the process of the fixing seat 30 being fitted onto the microphone 11, the guide slope slides in contact with the radial protrusion 12, forming a low-friction friction pair, which effectively reduces the assembly resistance and allows the fixing seat 30 to be smoothly fitted into the designated position without the need to apply a large additional force.

[0027] The upper end of the fixed seat 30 is provided with an inwardly extending step structure 33. When the fixed seat 30 is fitted into place, the lower surface of the step structure 33 abuts against the upper surface of the edge of the radial protrusion 12, which can restrict the fixed seat 30 from moving downward, and achieve bidirectional limiting in conjunction with the limiting plate 48.

[0028] In the locked state, the upper surface of the limiting plate 48 is in close contact with the lower surface of the radial protrusion 12, preventing the fixing seat 30 from coming off upward. This two-way limiting structure can ensure that the fixing seat 30 remains in place even under the action of lateral wind or violent shaking of the microphone, preventing the windproof cotton from loosening, rotating and falling off, so that the windproof position is always aligned with the center of the diaphragm, ensuring a stable and consistent wind noise suppression effect.

[0029] In the disassembled state, the user presses the release handle 42, using the connection 41 as a fulcrum to drive the latch claw 45 to open outward, thereby releasing the engagement between the limiting plate 48 and the radial protrusion 12. At this time, the user can pull the fixing base 30 upward to complete the disassembly. The operation is convenient and efficient, requiring no additional tools, and significantly improving the operational efficiency in continuous recording scenarios.

[0030] The horizontal extension 35 of the fixing base 30 is provided with a clearance through hole 34 on the outer side of the connection between the fixing base 30 and the quick release buckle 41. The clearance through hole 34 provides sufficient space for the elastic deformation of the quick release buckle 41, avoids interference between the elastic arm 46 and the fixing base 30 during the deformation process, and ensures that the stress of the elastic arm 46 is always lower than the material yield limit after 10,000 opening and closing cycles, effectively extending the service life of the quick release buckle 41 and improving the durability of the entire fixing structure.

[0031] The windproof cotton body 21 has a hollow inner cavity 22 to accommodate the microphone 11. The size of the hollow inner cavity 22 is adapted to the head of the microphone 11, ensuring that the windproof cotton body 21 can accurately cover the microphone head and achieve the best windproof and noise reduction effect. A recessed groove 23 is provided on the lower inner side of the windproof cotton body 21. The release handle 42 is fitted into the recessed groove 23, and the outer side of the release handle 42 abuts against the inner side of the recessed groove 23. This design allows the release handle 42 to be hidden inside the recessed groove 23, with a smooth transition between the outer side and the outer contour of the windproof cotton body 21. This not only makes the overall appearance neat and beautiful but also effectively prevents accidental dislodgement of the windproof cotton due to accidental contact with the release handle 42 during use, improving the reliability of use. Preferably, the upper part of the release handle 42 can also be partially inserted into the windproof cotton body 21 and glued together, increasing the bonding strength between the quick-release buckle 41 and the windproof cotton body 21.

[0032] To further improve the rigidity and structural stability of the quick-release buckle 41, a first wedge-shaped reinforcing rib 44 is provided on the inner side of the release handle 42, and a second wedge-shaped reinforcing rib 49 is provided on the outer side of the buckle claw 45. The reinforcing ribs can disperse stress and prevent the quick-release buckle 41 from breaking or deforming during repeated opening and closing, ensuring its structural integrity for long-term use. Preferably, the first wedge-shaped reinforcing rib 44 and the second wedge-shaped reinforcing rib 49 are several ribs with an inclined structure. The ribs of the first wedge-shaped reinforcing rib 44 are connected to the release handle 42 and the bending part 43 respectively, and the ribs of the second wedge-shaped reinforcing rib 49 are connected to the buckle claw 45 and the bending part 43 respectively, so as to strengthen the structural strength of the bending part 43 and prevent excessive shearing and tearing forces on the bending part 43 due to the deformation of the release handle 42 and the buckle claw 45, thereby strengthening the structural strength of the quick-release buckle 41.

[0033] The mounting base 30 also features several shock-absorbing structures, specifically including two shock-absorbing notches 51 arranged side-by-side on the upper edge of the mounting base 30. The surrounding structure 31 between the two shock-absorbing notches 51 forms a cantilever rack 52, on which an elastic shock-absorbing ring 53 is fitted. The elastic shock-absorbing ring 53 is made of rubber and has good elasticity and shock absorption performance. After assembly, the elastic shock-absorbing ring 53 is compressed between the windproof cotton body 21 and the mounting base 30, and between the mounting base 30 and the microphone 11. This converts rigid vibrations such as hand friction and low-frequency collisions into elastic micro-displacements, significantly reducing the transmission of vibration noise to the diaphragm, effectively improving recording purity, and further optimizing the windproof noise reduction effect.

[0034] The assembly process of this utility model is as follows: First, the fixed base 30 and the windproof cotton body 21 are assembled. The bottom of the windproof cotton body 21 is aligned with the fixing groove 36 of the fixed base 30. The two are firmly connected by special glue or interference fit to ensure reliable connection and avoid relative displacement between the windproof cotton body 21 and the fixed base 30 during use. Next, the overall structure is assembled with the microphone 11. Holding the fixing base 30, its through hole 32 is aligned with the head of the microphone 11, and it is slowly put down. During this process, the guide slope at the lower end of the hook 47 slides into contact with the radial protrusion 12 of the microphone 11. Under the guidance of the guide slope, the elastic arm 46 elastically deforms outward. As the fixing base 30 continues to move downward, when the lower surface of the step structure 33 abuts against the upper surface of the radial protrusion 12, the fixing base 30 reaches the preset assembly position. At this time, the elastic arm 46 resets under its own elasticity, and the limiting plate 48 of the hook 47 abuts against the lower surface of the radial protrusion 12, completing the locking action. The entire assembly process does not require additional tools and can be completed quickly with one hand, making the operation simple and efficient.

[0035] The disassembly process of this utility model is as follows: When it is necessary to disassemble the windproof cotton, the user pinches the sides of the windproof cotton body 21 near the bottom with his / her fingers. At this time, the fingers will press the release handle 42 hidden in the sink 23. The release handle 42 rotates with the connection 41 with the fixed seat 30 as the fulcrum, which drives the bending part 43 and the buckle claw 45 to rotate outward. The elastic arm 46 undergoes elastic deformation again, and the limiting plate 48 disengages from the lower surface of the radial protrusion 12, releasing the limitation on the fixed seat 30. Then, gently pull the windproof cotton body 21 upward to drive the fixed seat 30 to detach from the microphone 11, completing the disassembly. The entire disassembly process does not require additional tools, is easy to operate, and will not cause damage to the microphone 11 or the windproof cotton body 21. After disassembly, the fixed seat 30 and the windproof cotton body 21 remain connected, which is convenient for subsequent reassembly and use.

[0036] This invention utilizes the lever cooperation between the fixing base 30 and the quick-release buckle 41 to achieve rapid locking and releasing of the windproof cotton body 21, eliminating the rotation or binding actions required in traditional fixing methods and significantly improving operational efficiency. The bidirectional limiting structure ensures stable installation of the windproof cotton, effectively preventing loosening, rotation, and detachment. The shock-absorbing structure reduces vibration noise transmission and improves recording quality. The concealed release handle 42 design ensures a clean appearance and prevents accidental contact. The one-piece injection-molded fixing base 30 reduces the number of parts, controls overall weight, and facilitates maintenance. These technical features work synergistically to solve many problems existing in the prior art, achieving comprehensive performance improvements in quick assembly / disassembly, stable anti-loosening, lightweight design, universal compatibility, and long service life, thus possessing broad application prospects.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the protection scope of this utility model.
