Description

Technical Field

[0001] This utility model relates to the field of audio acquisition equipment technology, and in particular to a real-time intelligent voice microphone based on noise reduction technology. Background Technology

[0002] As a key audio device that converts sound signals into electrical signals, the structural stability of a microphone directly affects the signal acquisition quality. With the increasing prevalence of mobile conferencing, outdoor recording, and other scenarios, higher demands are being placed on the microphone's anti-interference capabilities and connection reliability.

[0003] In the prior art, such as the patent with announcement number CN221177886U, a deep noise reduction smart voice microphone is disclosed, in which the bottom shell and the microphone body are detachably connected through an internal threaded connection part, an external threaded connection part and a spring positioning pin.

[0004] However, this single locking structure has obvious limitations in practical use: the spring positioning pin is easily separated from the limiting hole by vibration or external force, causing the bottom shell to loosen. This not only reduces the overall stability of the microphone, but may also introduce noise due to the relative displacement of the components, affecting the clarity of audio acquisition. This problem is more prominent in complex scenarios such as mobile or outdoor environments.

[0005] Therefore, there is an urgent need for a real-time intelligent voice microphone based on noise reduction technology that can achieve multiple locking and improve connection stability. Summary of the Invention

[0008] As a preferred technical solution, the upper structure includes a microphone body and an inner ring sleeve. The inner ring sleeve is integrally formed on the bottom of the microphone body. The outer surface of the inner ring sleeve is threadedly connected to the inner wall surface of the middle ring sleeve. The cavity is opened on the microphone body, and the microphone body has a through hole for the positioning post to pass through.

[0009] As a preferred technical solution, an annular gap is formed between the inner ring sleeve and the microphone body, allowing the middle ring sleeve to be inserted. The two sides of the through hole cavity are respectively connected to the annular gap and the cavity. A positioning step is provided at the upper part of the annular gap cavity.

[0010] As a preferred technical solution, the snap-fit ​​component includes an outer ring sleeve and a protrusion.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-7 This utility model provides a real-time intelligent voice microphone based on noise reduction technology, including an upper structure 100 and a lower structure 200, with a docking structure 300 between the upper structure 100 and the lower structure 200. The lower structure 200 includes a handle 210 and a connector 220. The handle 210 is detachably connected to the bottom of the upper structure 100 via the docking structure 300, and the connector 220 is located at the top of the handle 210. The connector 220 includes a central ring 221 integrally formed on the top of the handle 210. The docking structure 300 includes a snap-fit ​​member 310 and a locking member 320. The snap-fit ​​member 310 is movably disposed on the outer surface of the connector 220 to achieve a limiting connection between the upper structure 100 and the lower structure 200, and the locking member 320 is located at the top of the handle 210. On the upper structure 100, a locking connection is achieved between the upper structure 100 and the snap-fit ​​member 310. The locking member 320 includes a cavity 321 on the upper structure 100. A spring 322 is fixedly connected to one side of the cavity 321. A positioning post 323 is fixedly connected to one end of the spring 322. One end of the positioning post 323 extends through the outer side of the cavity 321. A slot 324 adapted to the middle ring sleeve 221 is opened at the bottom of its surface. The top of the middle ring sleeve 221 is inserted into the cavity of the slot 324. The insertion and engagement of the middle ring sleeve 221 and the slot 324, combined with the locking effect of the snap-fit ​​member 310 and the locking member 320, forms a multiple lock, which solves the problem of easy loosening of the single locking structure and provides a structural basis for the overall connection stability.

[0020] It should be noted that the working principle of the microphone body 110 is consistent with that of a deep noise-reducing intelligent voice microphone disclosed in the existing announcement number CN221177886U. By covering the microphone head with noise-reducing cotton, as well as an electromagnetic shielding layer and a sound insulation layer, the noise-reducing cotton can play a role in noise reduction, while the electromagnetic shielding layer can shield the microphone head from interference from external electromagnetic signals, and the sound insulation layer can isolate external sounds, resulting in better noise reduction effect. Furthermore, with the combined effect of the microphone cover and the filter, the filter filters high-frequency and low-frequency signals, further improving the noise reduction effect of the voice microphone and making the voice microphone perform better.

[0021] The "noise reduction technology" of this utility model not only refers to the integration of existing deep noise reduction structures (such as the noise reduction structure in the patent document with announcement number CN221177886U) into the microphone body 110, but also reduces vibration noise caused by component loosening by optimizing the docking stability of the upper structure 100 and the lower structure 200. This noise is a key interference source affecting the noise reduction effect. Existing noise reduction structures mainly filter ambient sound waves and cannot eliminate mechanical vibration noise caused by component loosening. The multi-locking structure of this utility model can avoid relative displacement of the connection parts and mechanically assist in maintaining the stable working environment of the noise reduction structure, thereby achieving synergistic effect of structural anti-shake and structural noise reduction.

[0022] The upper structure 100 includes a microphone body 110 and an inner ring sleeve 120. The microphone body 110 adopts a multi-directional design and can switch the directional mode according to the usage scenario. The inner ring sleeve 120 is integrally formed on the bottom of the microphone body 110. The outer surface of the inner ring sleeve 120 is threadedly connected to the inner wall of the middle ring sleeve 221. The cavity 321 is opened on the microphone body 110, and the microphone body 110 has a through hole for the positioning post 323 to pass through. The threaded connection between the inner ring sleeve 120 and the middle ring sleeve 221 enhances the initial connection strength and sealing between the upper structure 100 and the lower structure 200. At the same time, it limits the setting position of the cavity 321 and the positioning post 323, providing an installation basis for the locking function of the locking member 320, so that the threaded connection and the subsequent locking operation work together to improve the connection reliability.

[0023] The inner ring sleeve 120 and the microphone body 110 form an annular gap that allows the middle ring sleeve 221 to be inserted. The two sides of the through hole cavity are connected to the annular gap and the cavity 321 respectively. The upper part of the annular gap cavity is provided with a positioning step for limiting the tightening position of the middle ring sleeve 221. Through the annular gap formed by the inner ring sleeve 120 and the microphone body 110 and the positioning step, the tightening position of the middle ring sleeve 221 is precisely limited, ensuring that the protrusion 312 and the groove 111 are aligned, avoiding the failure of the locking due to position deviation, and ensuring the accuracy of subsequent locking operations.

[0024] The snap-fit ​​component 310 includes an outer ring sleeve 311 and a protrusion 312. The outer ring sleeve 311 is movably fitted onto the outer surface of the middle ring sleeve 221. The top of the outer ring sleeve 311 is integrally formed with a protrusion 312. The surface of the microphone body 110 is provided with a groove 111 that matches the protrusion 312. The protrusion 312 snaps into the inner cavity of the groove 111. By snapping the protrusion 312 of the outer ring sleeve 311 into the groove 111 of the microphone body 110, the circumferential positioning of the upper and lower structures is achieved, preventing relative rotation between the two. The threaded connection further enhances the torsional resistance of the overall structure.

[0025] The protrusion 312 has a through-hole 3121 that is compatible with the positioning post 323. The inner wall surfaces of the positioning hole 3121 and the through hole are slidably connected to the surface of the positioning post 323. By cooperating with the positioning post 323 through the positioning hole 3121 on the protrusion 312, the positioning post 323 can pass through the positioning hole 3121 to achieve axial locking of the protrusion 312, which firmly connects the snap-fit ​​310 to the upper structure 100, prevents the protrusion 312 from falling out of the groove 111, and enhances the stability of the snap-fit ​​310.

[0026] The outer ring 311 has an annular groove 3111 on its inner wall surface, and the middle ring 221 has a protruding ring 2211 integrally formed on its outer surface. The protruding ring 2211 is slidably connected to the inner wall surface of the annular groove 3111, and the movable height of the protruding ring 2211 in the inner cavity of the annular groove 3111 is equal to the inner cavity height of the slot 324. By cooperating with the annular groove 111 of the outer ring 311 and the protruding ring 2211 of the middle ring 221, the movable height of the outer ring 311 is limited, ensuring that when the protrusion 312 is inserted into the groove 111, the middle ring 221 is just fully inserted into the slot 324, so that the snap-fit ​​locking and the insertion locking are completed simultaneously, ensuring the synergy of multiple locking.

[0027] The locking component 320 also includes a groove 325 and a slider 326. The groove 325 is formed on one side of the cavity 321, and the slider 326 is slidably connected in the groove 325 and fixedly connected to the surface of the positioning post 323. The length of the groove 325 is not less than the maximum moving distance of the positioning post 323. Through the cooperation of the groove 325 and the slider 326, the positioning post 323 is guided to move smoothly along a fixed trajectory, avoiding the positioning post 323 from shifting or getting stuck during the extension and retraction process, ensuring smooth locking and unlocking operations, and improving the durability of the structure.

[0028] The bottom of the positioning post 323 is provided with a slope, and the height of the side of the slope near the spring 322 is lower than the height of the opposite side. Through the slope design at the bottom of the positioning post 323, the protrusion 312 can automatically push the positioning post 323 to compress the spring 322 when it moves upward. The locking and engagement can be completed without manually adjusting the position of the positioning post 323, which simplifies the assembly operation and improves the ease of use.

[0029] The working principle of this utility model is as follows: Initial connection: First, invert the upper structure 100 and the lower structure 200, aligning the middle ring 221 of the lower structure 200 with the inner ring 120 of the upper structure 100, aligning the protrusion 312 with the groove 111. At this time, the outer ring 311 of the snap-fit ​​310 moves downward under its own weight, causing the protrusion 2211 to slide within the annular groove 3111 until it reaches its maximum limit. At this point, the middle ring 221 will not obstruct the positioning hole 3121. Figure 5 As shown; Threaded connection: By rotating the handle 210 via the thread, the handle 210 drives the middle ring sleeve 221 and the convex ring 2211 to rotate synchronously. Under the action of the thread, the middle ring sleeve 221 gradually enters the annular gap formed by the inner ring sleeve 120 and the microphone body 110, and the convex ring 2211 rotates within the annular groove 3111, as... Figure 6 As shown; Snap-fit ​​locking: The middle ring 221 moves downward under the action of the thread, and the convex ring 2211 on its outer surface slides along the annular groove 3111 of the outer ring 311, causing the outer ring 311 to move downward synchronously; at this time, the protrusion 312 on the outer ring 311 moves with the outer ring 311 and gradually snaps into the groove 111 of the microphone body 110. During the movement, the protrusion 312 contacts the inclined surface of the positioning post 323, pushing the positioning post 323 to compress the spring 322 and move into the cavity 321 until the protrusion 312 is completely snapped into the groove 111. The positioning post 323 loses its constraint and resets under the elastic force of the spring 322, passing through the positioning hole 3121 of the protrusion 312 and locking the protrusion 312 in the groove 111. Figure 7 As shown; Plug-in locking: At this time, the protrusion 312 has been fully engaged in the groove 111, and the positioning pin 323 has penetrated the positioning hole 3121. Continue to rotate the handle 210, so that the handle 210 drives the middle ring sleeve 221 and the protrusion ring 2211 to continue to move until the middle ring sleeve 221 abuts against the positioning step. Then, the middle ring sleeve 221 is fully inserted into the slot 324 of the positioning pin 323. Thus, through the threaded connection, the engagement of the protrusion 312 and the groove 111, the locking of the positioning pin 323 and the positioning hole 3121, and the insertion of the middle ring sleeve 221 and the slot 324, a synergistic effect is achieved to realize multiple locking. Unlocking and disassembly: Push the positioning post 323 into the cavity 321 to compress the spring 322 so that it is disengaged from the positioning hole 3121. Then rotate the lower structure 200 in the opposite direction to separate the upper structure 100 from the lower structure 200 and complete the disassembly.

[0030] Through the above process, the connection is stable and the operation is convenient, ensuring that the real-time intelligent voice microphone based on noise reduction technology can work stably in various scenarios.
