Description

Technical Field

[0001] This invention relates to the field of microphone technology, and more particularly to a shockproof structure for a desktop microphone and a desktop microphone having a shockproof structure. Background Technology

[0002] Desktop microphones, as highly sensitive sound acquisition devices, are widely used in scenarios such as meetings, office work, game streaming, and recording production. Because the microphone module is extremely sensitive to vibration, mechanical vibrations transmitted through the desktop (such as keyboard clicks, the sound of a water glass being placed, or the sound of the desk colliding) are easily captured by the microphone module, forming low-frequency noise (such as a rumbling sound), which seriously affects recording quality. Therefore, a shock-resistant structure is an indispensable component of desktop microphones.

[0003] Existing desktop microphone shock protection solutions are mainly divided into two types: external and internal, but both have certain limitations: External suspension shock mounts (commonly known as "spider mounts"): This structure suspends the microphone in the center of an external bracket using elastic cords or rubber bands. While offering good shock absorption, they are bulky and complex, taking up valuable desk space and potentially obscuring the user's face during live video streaming or meetings, affecting visual appeal and user experience. Furthermore, the rubber bands need frequent replacement as they age and loosen, resulting in high maintenance costs.

[0004] Traditional built-in simple shock-absorbing structures: In pursuit of aesthetics and compactness, some microphones attempt to incorporate shock-absorbing structures. However, existing built-in solutions typically only involve filling the space between the microphone assembly and the housing with a simple rubber block or sponge pad. This method relies solely on the material's own elasticity for passive shock absorption, lacking effective buffer travel and damping media. When subjected to significant impacts or low-frequency vibrations, the simple rubber structure is prone to excessive deformation, leading to a hard "bottoming out" contact, or it may fail to effectively dissipate vibrational energy, resulting in a shock-absorbing effect far inferior to external shock mounts. Summary of the Invention

[0005] In view of the problems mentioned above, such as the bulky size and obstruction of vision of the external hanging shock mount in the prior art, and the easy occurrence of "bottoming out" hard contact and poor low-frequency shock absorption effect of the traditional built-in simple shock-absorbing structure, the present invention provides a shock-absorbing structure for desktop microphones to solve the above technical problems.

[0006] The technical solution adopted by this invention to solve its technical problem is: a shockproof structure for a desktop microphone, the shockproof structure including a support component and an elastic shock-absorbing frame. The support component has a receiving cavity and a first opening communicating with the receiving cavity. The first opening is used for mounting the microphone component so that the microphone component can be partially placed into the receiving cavity. The elastic shock-absorbing frame has a first elastic buffer portion. The elastic shock-absorbing frame is installed at the first opening and sleeved on the microphone component. The first elastic buffer portion is located between the microphone component and the support component. The elastic shock-absorbing frame and the inner wall of the receiving cavity enclose a shock-absorbing cavity. When the microphone component is subjected to external vibration, the air in the shock-absorbing cavity forms an air buffer layer, which, together with the elastic deformation of the first elastic buffer portion of the elastic shock-absorbing frame, buffers and absorbs the vibration of the microphone component.

[0007] The beneficial effects of this invention are as follows: This invention provides a shock-absorbing structure for desktop microphones. By enclosing the microphone within the cavity of the supporting component to form a shock-absorbing chamber, when the microphone assembly is subjected to vibrations from the desktop or external environment, the air within the shock-absorbing chamber forms an air buffer layer with certain damping characteristics during vibration transmission. This air buffer layer effectively hinders the direct transmission of vibration energy. Simultaneously, the first elastic buffer portion of the elastic shock-absorbing frame undergoes elastic deformation under vibration, further absorbing and buffering vibration impacts using the elastic restoring force of its own material. The air buffer layer and the first elastic buffer portion work synergistically, significantly improving the buffering effect against vibrations of different frequencies and intensities compared to traditional built-in shock-absorbing structures that rely solely on the elasticity of a single material. This effectively suppresses the transmission of low-frequency vibrations and avoids the "bottoming out" hard contact problem that easily occurs with simple rubber structures. Furthermore, the built-in shock-absorbing structure eliminates the need for bulky external suspension components, effectively reducing the overall size of the microphone, saving desktop space, and resulting in a simpler and more aesthetically pleasing appearance that does not obstruct video playback, thus balancing excellent shock absorption performance with a superior user experience.

Detailed Implementation

[0010] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0011] Please see Figures 1-17 The present invention provides a shockproof structure 200 for a desktop microphone. The desktop microphone includes a microphone body and a microphone assembly 10 (such as a dynamic microphone). The shockproof structure 200 includes a rigid support assembly 20 and a soft elastic shock-absorbing frame 30. The elastic shock-absorbing frame 30 is preferably made of silicone material, but it can also be made of materials with good elasticity and aging resistance, such as rubber and EVA.

[0012] Specifically, the support assembly 20 has a receiving cavity 21 and a first opening 22 communicating with the receiving cavity 21. The receiving cavity 21 is disposed on the top of the support assembly 20, and the first opening 22 is used for the installation of the microphone assembly 10 so that the microphone assembly 10 can be partially placed into the receiving cavity 21. The elastic shock absorber frame 30 has a first elastic buffer portion 31. The elastic shock absorber frame 30 is installed at the first opening 22 and sleeved on the microphone assembly 10. The first elastic buffer portion 31 is located between the microphone assembly 10 and the support assembly 20. The elastic shock absorber frame 30 and the inner wall of the receiving cavity 21 form a shock absorber cavity 201. When the microphone assembly 10 is subjected to external vibration, the air in the shock absorber cavity 201 forms an air buffer layer, which, together with the elastic deformation of the first elastic buffer portion 31 of the elastic shock absorber frame 30, buffers and absorbs the vibration of the microphone assembly 10. This structure, by placing the microphone assembly 10 part inside the support assembly 20 and using the elastic damping frame 30 as the sole connection medium for the microphone assembly 10, physically severs the rigid sound transmission path between the support assembly 20 and the microphone assembly 10, preventing vibration from being directly transmitted to the microphone assembly 10 through hard materials such as metal or plastic. Simultaneously, when the microphone assembly 10 experiences a slight displacement due to vibration, the air within the damping cavity 201 is compressed or expanded, forming a dynamic air damping force. This damping force effectively dissipates vibration energy, especially showing significant absorption of low-frequency vibrations. The first elastic buffer 31, as an elastic structure directly connecting the microphone assembly 10 and the support assembly 20, not only provides initial buffering through its own elastic deformation but also further dissipates vibration energy during vibration through molecular friction within the material, forming a "double damping" effect with the air buffer layer. This results in excellent overall shock absorption while overcoming the drawbacks of large size and unsightly appearance of external shock absorbers.

[0013] In this embodiment, as Figure 4 , Figure 8 , Figure 16The elastic shock absorber frame 30 includes a sleeve edge 32 for fitting the support assembly 20, a support sleeve 33 for fitting the microphone assembly 10, and a first elastic buffer portion 31, which is connected to the sleeve edge 32 and the support sleeve 33. By setting the sleeve edge 32 and the support sleeve 33, and connecting them with the first elastic buffer portion 31, an independent and flexible support frame for the microphone assembly 10 is formed. Specifically, the sleeve edge 32 can be firmly combined with the support assembly 20, ensuring that the entire elastic shock absorber frame 30 is accurately and reliably positioned on the support assembly 20, providing a stable foundation for subsequent shock absorption. Because the sleeve edge 32 can deform elastically, it can be directly fitted onto the outside of the support assembly 20. The support sleeve 33 tightly fits the microphone assembly 10, so that the weight of the microphone assembly 10 can be evenly distributed on the support sleeve 33. When the support assembly 20 is subjected to external vibration, the vibration is first transmitted to the sleeve edge 32. At this time, the first elastic buffer part 31, as the elastic medium connecting the two, can immediately undergo elastic deformation, initially absorbing and buffering the transmitted vibration, greatly reducing the direct transmission of vibration to the support sleeve 33 and microphone assembly 10. The sleeve edge 32, support sleeve 33, and first elastic buffer are integrally formed, ensuring that the force transmission between the sleeve edge 32, support sleeve 33, and first elastic buffer part 31 is more direct and uniform, avoiding stress concentration caused by gaps or rigid connection points in the connection parts during vibration transmission, and further optimizing the vibration reduction effect.

[0014] In this embodiment, as Figure 4 , Figure 9 The inner side of the sleeve edge 32 is provided with a second snap-fit ​​groove 321, and the outer wall of the support component 20 is provided with a snap-fit ​​protrusion 24 that snaps into the second snap-fit ​​groove 321, so that the sleeve edge 32 is installed on the outer wall of the support component 20. The cooperation between the second snap-fit ​​groove 321 and the snap-fit ​​protrusion 24 enables quick assembly between the elastic shock absorber 30 and the support component 20. When the sleeve edge 32 of the elastic shock absorber 30 is fitted onto the outer wall of the support component 20, the snap-fit ​​protrusion 24 will snap into the second snap-fit ​​groove 321, forming a mechanical limit, effectively preventing the elastic shock absorber 30 from axial or circumferential displacement due to vibration or accidental contact during microphone use, ensuring that the elastic shock absorber 30 is always in the preset installation position. The snap-fit ​​structure eliminates the need for additional fasteners (such as screws or glue), simplifying the assembly process, reducing production costs, and facilitating subsequent maintenance and replacement.

[0015] In this embodiment, as Figure 4 , Figure 8 , Figure 9 , Figure 15 , Figure 16The support assembly 20 includes a cylindrical bracket 23, with the receiving cavity 21 axially disposed on the cylindrical bracket 23. The first opening 22 is disposed on the cylindrical bracket 23, and the sleeve edge 32 is located at the first opening 22 and connected to the side wall of the cylindrical bracket 23. The cylindrical bracket 23 provides a load-bearing foundation, and the cylindrical bracket 23 is preferably cylindrical. The cylindrical structure design facilitates the uniform distribution of air inside the receiving cavity 21. When the microphone assembly 10 vibrates, the air in the damping cavity 201 can more evenly form an air buffer layer, improving the overall damping consistency.

[0016] In this embodiment, as Figure 2-4 and Figure 8-10 The support assembly 20 also includes a bottom cover 26 with a fourth opening 261. The cylindrical bracket 23 has a second opening 25 relative to the first opening 22 and communicating with the receiving cavity 21. The bottom cover 26 can be detachably closed to cover the second opening 25, which allows the microphone assembly 10's wires to pass through. This detachable connection design between the bottom cover 26 and the cylindrical bracket 23 provides a convenient channel for the installation, debugging, and maintenance of the microphone's internal components. When it is necessary to operate on the microphone assembly 10 or related circuitry within the receiving cavity 21, the bottom cover 26 can be easily removed and then re-closed after the operation is completed, without the need to disassemble the entire support assembly 20, significantly improving assembly efficiency and ease of subsequent maintenance. Simultaneously, the fourth opening 261 on the bottom cover 26, in conjunction with the second opening 25 of the cylindrical bracket 23, provides a standardized path for the wires connected to the microphone assembly 10 (such as signal cables, power cables, etc.), ensuring neat and orderly wire arrangement and reducing the risk of malfunctions caused by wire tangling or compression.

[0017] In this embodiment, Figure 1-10 As shown, the support assembly 20 also includes a support ring 27, and the sleeve edge 32 is fitted onto the outer side wall of the columnar bracket 23. The support ring 27 is fitted onto the sleeve edge 32 by an interference fit (e.g., Figures 8-10 (As shown), however, the support ring 27 and the column bracket 23 can also be integrally formed, with an insertion slot 320 between the support ring 27 and the column bracket 23 for the insertion of the sleeve edge 32 (as shown). Figure 3(As shown). The interference fit of the support ring 27 further enhances the connection stability between the elastic shock absorber 30 and the column bracket 23. The support ring 27 is made of a rigid material (such as ABS plastic or metal), and its inner wall fits tightly against the outer wall of the sleeve edge 32, applying continuous radial pressure to the sleeve edge 32. This makes the second snap-fit ​​groove 321 on the inner side of the sleeve edge 32 engage more firmly with the snap-fit ​​protrusion 24 on the outer side of the column bracket 23, effectively preventing the sleeve edge 32 from loosening or falling off due to vibration during long-term use. At the same time, the support ring 27, sleeved on the sleeve edge 32, can stabilize the microphone assembly 10. Without the support ring 27, when the microphone assembly 10 is inserted into the elastic shock absorber 30, the excessive weight of some microphone assemblies 10 may cause the elastic shock absorber 30 to deform under the weight of the microphone assembly 10, affecting the installation verticality and stability of the microphone assembly 10. The support ring 27, through its rigid constraint on the sleeve edge 32, can limit the excessive radial deformation of the elastic damping frame 30, ensuring that the microphone assembly 10 always maintains the preset posture and position during operation, and avoiding the impact of posture deviation on the sound pickup effect.

[0018] In this embodiment, Figure 8 As shown, the support ring 27 has an inwardly extending lip plate 271 near the first opening 22. The inner wall of the lip plate 271 abuts against / approaches the outer wall of the first elastic buffer portion 31. The lip plate 271, by abutting against / approaching the outer wall of the first elastic buffer portion 31, provides radial limiting support for the first elastic buffer portion 31. When the microphone assembly 10 experiences a significant radial displacement due to vibration, the first elastic buffer portion 31 expands outward. At this time, the lip plate 271 effectively blocks it, preventing the first elastic buffer portion 31 from exceeding its elastic limit due to excessive deformation, thereby preventing a hard contact that "bottoms out." Simultaneously, the abutment of the lip plate 271 also allows the first elastic buffer portion 31 to maintain a relatively stable shape during vibration, ensuring that its elastic deformation is mainly concentrated in the preset damping direction, further optimizing the energy absorption efficiency of the elastic buffer portion.

[0019] In this embodiment, Figure 8As shown, a positioning plate 272 extends from the end of the support ring 27 away from the lip plate 271. The positioning plate 272 has a positioning hole 273, and the column bracket 23 has a positioning protrusion 231 corresponding to the positioning hole 273. The positioning hole 273 is detachably sleeved on the positioning protrusion 231. This structure achieves precise positioning and stable connection between the support ring 27 and the column bracket 23. The cooperation between the positioning hole 273 and the positioning protrusion 231 allows for quick determination of the circumferential and axial positions of the support ring 27 during assembly, ensuring that the lip plate 271 on the support ring 27 accurately corresponds to the first elastic buffer part 31, avoiding any impact on the limiting and supporting effect of the elastic shock absorber 30 due to misalignment of the support ring 27. The detachable sleeve connection method ensures connection reliability while also facilitating the installation and removal of the support ring 27. For example, when it is necessary to replace the elastic shock absorber 30, the support ring 27 can be removed first, making the operation more convenient. The positioning protrusion 231 can also play a certain role in preventing the support ring 27 from rotating due to vibration during microphone use, ensuring that the lip plate 271 can always provide effective radial support to the first elastic buffer part 31.

[0020] In this embodiment, Figure 1-5 As shown, the elastic shock absorber 30 has a first embodiment structure: the elastic shock absorber 30 includes a first cylindrical body suspended within the receiving cavity 21, and a sealing cover 34 disposed at one end of the first cylindrical body and integrally connected to the first cylindrical body. The sealing cover 34 is disposed at the first opening 22. The first cylindrical body is used to sleeve and wrap the microphone assembly 10. The first cylindrical body is a support sleeve 33, and the sealing cover 34 is composed of the sleeve edge 32 and the first elastic buffer portion 31. The outer wall of the first cylindrical body, the first elastic buffer portion 31, and the side wall of the receiving cavity 21 cooperate to form the shock absorber cavity 201. By forming a wrapping sleeve around the microphone assembly 10 through the first cylindrical body, a uniform support force can be provided to the microphone assembly 10 in the circumferential direction, ensuring the stable placement of the microphone assembly 10 within the receiving cavity 21. The sealing cover 34 is located at the first opening 22, which not only connects the elastic damping frame 30 to the support assembly 20, but also provides a certain degree of sealing to the top opening of the receiving cavity 21, reducing air leakage in the damping cavity 201 and enhancing the damping effect of the air buffer layer. When external vibrations are transmitted to the support assembly 20, the first elastic buffer part 31 in the sealing cover 34 first undergoes elastic deformation to initially absorb the vibration. At the same time, the air in the damping cavity 201 between the outer wall of the first cylindrical body and the side wall of the receiving cavity 21 is compressed or expanded to form an air buffer layer, further hindering the transmission of vibrations to the microphone assembly 10. The enveloping first cylindrical body also provides a certain degree of protection for the microphone assembly 10, reducing the impact of external dust, moisture, etc. on the microphone assembly 10.

[0021] In a further embodiment, the elastic damping frame 30 also includes an elastic sealing element 35. The elastic sealing element 35 is detachably connected to the end of the first cylindrical body opposite to the sealing cover 34. The periphery of the elastic sealing element 35 is tightly connected to the side wall inside the receiving cavity 21, so that the elastic sealing element 35, the side wall of the receiving cavity 21, the first elastic buffer part 31, and the outer peripheral wall of the first cylindrical body together form the damping cavity 201. By providing the detachable elastic sealing element 35, effective support and sealing can be provided for the bottom of the first cylindrical body. In conjunction with the first elastic buffer part 31 of the sealing cover 34, the damping cavity 201 is completely sealed between the outer peripheral wall of the first cylindrical body and the side wall of the receiving cavity 21, preventing air leakage from the opening at the bottom of the support assembly 20 inside the damping cavity 201, ensuring the integrity and stability of the air buffer layer, and thus ensuring the reliable performance of the air damping damping effect. On the other hand, the elastic seal 35 is tightly connected to the side wall of the receiving cavity 21, allowing it to undergo elastic deformation during vibration transmission, thus improving the overall shock absorption performance of the microphone. Furthermore, the tight fit between the elastic seal 35 and the first cylindrical body and the side wall of the receiving cavity 21 further enhances the stability of the first cylindrical body within the receiving cavity 21, preventing unnecessary shaking or displacement when subjected to vibration, and ensuring that the microphone assembly 10 remains in a stable working position. The detachable connection facilitates the replacement and maintenance of the elastic seal 35, eliminating the need for complex disassembly or modification of the microphone body structure during installation.

[0022] In this embodiment, Figure 6-12 As shown, the elastic shock absorber 30 also has a second embodiment structure: the first cylindrical body and the elastic sealing element 35 are integrally formed. This integral forming enhances the overall structural strength and fatigue resistance of the elastic shock absorber 30, extends its service life, and avoids the decrease in shock absorption effect caused by aging or loosening of connecting parts in a split structure. It also simplifies the assembly process, reduces the number of parts, and lowers production costs and assembly errors. The integrally formed first cylindrical body and elastic sealing element 35 can form a more complete and tighter sealing structure. Simultaneously, the integral structure makes the support of the elastic sealing element 35 on the first cylindrical body more direct and uniform. When the microphone assembly 10 is subjected to vibration, the elastic deformation of the elastic sealing element 35 can respond more quickly and work in conjunction with the first elastic buffer 31, improving the overall shock absorption response speed and buffering effect.

[0023] In this embodiment, Figure 3-12As shown, the elastic seal 35 includes a second elastic buffer portion 36 extending radially from the first cylindrical body towards the side wall of the receiving cavity 21, and a snap-fit ​​portion 37 that can snap into the first snap-fit ​​groove 232 provided on the side wall of the receiving cavity 21. The first elastic buffer portion 31, the second elastic buffer portion 36, the outer peripheral wall of the first cylindrical body, and the inner side wall of the support assembly 20 enclose and form a shock-absorbing cavity 201. Through the radial extension design of the second elastic buffer portion 36, it can generate radial elastic deformation when the microphone assembly 10 vibrates, further enhancing the vibration buffering capacity. The second elastic buffer portion 36 and the first elastic buffer portion 31 form an elastic support structure that corresponds to each other. When vibration is transmitted from the support assembly 20 to the elastic shock absorber 30, the two can absorb and dissipate vibration energy from different positions, improving the overall shock absorption efficiency. The engagement between the snap-fit ​​part and the first snap-fit ​​groove 232 on the side wall of the receiving cavity 21 enables precise positioning and stable installation of the elastic seal 35 within the receiving cavity 21, ensuring a tight connection between the elastic seal 35 and the side wall of the receiving cavity 21. This effectively prevents air leakage within the damping cavity 201 and safeguards the integrity of the air buffer layer. Simultaneously, the snap-fit ​​structure facilitates the installation and removal of the elastic seal 35, making future maintenance and replacement easier. The damping cavity 201, enclosed by the first elastic buffer part 31, the second elastic buffer part 36, the outer peripheral wall of the first cylindrical main body, and the inner side wall of the support assembly 20, forms a relatively enclosed space. When the microphone assembly 10 vibrates, the damping force generated by the compression or expansion of the air within the cavity, combined with the elastic deformation of the first and second elastic buffer parts 36, creates a triple damping structure, significantly improving the absorption effect of vibrations at different frequencies.

[0024] In this embodiment, Figure 11-12 As shown, both the first elastic buffer portion 31 and the second elastic buffer portion 36 protrude in an arc shape away from the outer side of the first cylindrical body, forming a concave buffer zone 39. This structure optimizes the energy absorption capacity of the elastic buffer portion. When vibration is transmitted to the first elastic buffer portion 31 or the second elastic buffer portion 36, the arc-shaped protrusion design allows the elastic material to deform more uniformly and fully along the arc surface when subjected to force. Compared to a plane or other shapes, the arc structure can provide a larger deformation space, thereby absorbing more vibration energy. The concave buffer zone 39 forms a "spring"-like structure during deformation, dissipating vibration energy through the bending and rebound of the curved surface, further improving the buffering effect. The concave buffer zone 39 can also guide the direction of vibration energy transmission to a certain extent, so that the vibration is absorbed more by the deformation of the elastic material itself, rather than being directly transmitted to the microphone assembly 10.

[0025] In this embodiment, Figure 11-12As shown, the outer surface of the first elastic buffer portion 31 is provided with abutting protrusions 38, which are used to abut against the periphery of the microphone assembly 10. Through the tight contact between the abutting protrusions 38 and the periphery of the microphone assembly 10, a stable circumferential limit is formed on the microphone assembly 10, preventing unnecessary shaking or displacement in the radial direction. This ensures the installation position accuracy of the microphone assembly 10 within the vibration damping cavity 201, avoiding any impact on the damping effect or sound pickup performance due to positional deviation. When the microphone assembly 10 is inserted into the first cylindrical body, the abutting protrusions 38 will make tight contact with the outer peripheral wall of the microphone assembly 10, forming multi-point or multi-line elastic compression. The frictional force generated by this compression can effectively limit the displacement of the microphone assembly 10 in the radial direction, preventing it from swaying or rotating due to vibration, shaking, or slight collisions during microphone use. The abutment ridges 38 also form a flexible buffer between the microphone assembly 10 and the first cylindrical body. When the microphone assembly 10 is subjected to axial or radial impact, the elastic deformation of the abutment ridges 38 can absorb part of the impact energy, further protecting the microphone assembly 10 from damage. The height and density of the abutment ridges 38 can be designed according to the size and weight of the microphone assembly 10 to ensure that sufficient clamping force is provided without causing excessive compression to the microphone assembly 10 and affecting its normal operation.

[0026] In this embodiment, Figure 6-10As shown, the shockproof structure 200 further includes a receiver 40 with a receiver cavity 42. The first cylindrical body has an axially penetrating receiving channel 41. When the microphone assembly 10 is partially placed into the receiving channel 41, the receiver 40 is installed within the receiving channel 41. The elastic shock-absorbing frame 30 wraps around the outside of the receiver 40, and the receiver 40 is fitted onto the microphone assembly 10. The tail end of the microphone assembly 10 extends to the outside of the support assembly 20 through a fourth opening 261 provided at the tail end of the support assembly 20. The receiver cavity 42 is arranged along the axial direction of the receiver 40 and is used to receive the sound from the microphone assembly 10. The receiver 40 provides an independent and enclosed receiver cavity 42 for the microphone assembly 10, which can effectively reduce the interference of external environmental noise on the microphone assembly 10, while enhancing the directional sound collection capability and improving the clarity and sensitivity of the sound pickup. The sound-receiving cavity 42 is arranged along the axial direction of the sound-receiving component 40, consistent with the sound wave receiving direction of the microphone assembly 10, ensuring that the sound signal can be directly and efficiently transmitted to the microphone assembly 10, reducing sound wave loss and scattering during propagation. The tail end of the microphone assembly 10 extends to the outside of the support component 20 through the fourth opening 261 at the tail end of the support component 20, making the sound reception effect of the microphone assembly 10 better. Because it extends to the outside of the housing through the sound-receiving component 40, the microphone can obtain a larger rear cavity air volume in a compact size, which significantly improves the low-frequency response of the dynamic microphone (making the sound thicker) and solves the acoustic defects of "dry sound and insufficient low frequency" that are common in small-volume microphones.

[0027] In this embodiment, Figure 8-9 As shown, the microphone 40 includes a second cylindrical body 43 and a cover 44. The second cylindrical body 43 has third openings 431 at both its front and rear ends. The third opening 431 at the front end of the second cylindrical body 43 is used to fit onto the microphone assembly 10. The cover 44 covers the third opening 431 at the rear end of the second cylindrical body 43. A notch 441 is provided at the edge of the cover 44. When the cover 44 covers the third opening 431 at the rear end of the second cylindrical body 43, the notch 441 and the inner wall of the second cylindrical body 43 form a wire hole 45, through which the wire of the microphone assembly 10 passes. This structure achieves a balance between functional integrity and ease of assembly for the microphone 40. The third opening 431 at the front and rear ends of the second cylindrical body 43 serves to mate with the microphone assembly 10 at the front end, ensuring precise alignment between the sound receiving cavity 42 and the pickup end of the microphone assembly 10. The rear end is covered by a cap 44, forming a relatively sealed sound receiving space to reduce interference from external stray sound waves and improve the purity of sound reception. The notch 441 on the edge of the cap 44, which mates with the inner wall of the second cylindrical body 43, forms a wire passage hole 45, providing a reasonable wiring path for the microphone assembly 10's wires.

[0028] In this embodiment, Figure 13-17 As shown, the elastic metal casing also has a third embodiment structure: the support assembly 20 has a second opening 25 communicating with the receiving cavity 21 opposite to the first opening 22; the elastic shock absorber frame 30 includes a first elastic shock absorber 50 and a second elastic shock absorber 60; the first elastic shock absorber 50 is located at the first opening 22 and is composed of the sleeve edge 32, the support sleeve 33, and the first elastic buffer portion 31; the second elastic shock absorber 60 covers the second opening 25; when the microphone assembly 10 is partially installed in the receiving cavity 21, the first elastic buffer portion 31, the second elastic shock absorber 60, and the side wall of the receiving cavity 21 form a shock-absorbing cavity 201. The complete shock-absorbing cavity 201 is formed by the cooperation of the elastic shock absorbers at the two openings. The first elastic damping member 50 is located at the first opening 22 and consists of a sleeve edge 32, a support sleeve 33, and a first elastic buffer part 31, which can wrap and elastically buffer one end of the microphone assembly 10; the second elastic damping member 60 covers the second opening 25 and provides support and buffer for the other end of the microphone assembly 10. After the second elastic damping member 60 is connected to the inner wall of the receiving cavity 21, the tail of the microphone assembly 10 can be connected by bolts 101 (e.g., Figure 16-17 When the microphone assembly 10 is partially installed in the receiving cavity 21, the first elastic buffer 31, the second elastic damping member 60, and the side wall of the receiving cavity 21 together form a damping cavity 201. This damping cavity 201 encloses most of the structure of the microphone assembly 10, ensuring that external vibrations transmitted from the support assembly 20 to the microphone assembly 10 pass through the elastic deformation of the first elastic buffer 31 or the second elastic damping member 60, as well as the damping effect of the air buffer layer within the damping cavity 201, thus achieving multi-stage absorption and dissipation of vibrations. This structure with elastic support at both ends effectively balances the force on the microphone assembly 10 in the axial direction, avoiding uneven force distribution and insufficient stability problems that may result from single-end support. Simultaneously, the dual elastic damping members increase the total amount of elastic deformation and the absorption pathways for vibration energy, further enhancing the overall shock absorption effect. In this embodiment, the support assembly 20 can be a single columnar bracket 23, such as... Figure 15-16 It has a simple structure and is easy to install, but it does not have a high demand for shock absorption. However, if some shock absorption effect is required, this solution can be used.

[0029] The shockproof structure 200 for a desktop microphone provided by the present invention offers three implementation methods. One method is an integrated elastic shock-absorbing frame. The shock-absorbing frame is preferably made of elastic silicone material through one-piece injection molding. It has a compact structure and simple manufacturing process. It can complete the overall molding of the sleeve edge 32, support sleeve 33, first elastic buffer part 31, second elastic buffer part 36 and snap-fit ​​part in one injection molding, which effectively reduces the assembly difficulty and production cost, while ensuring the stability and consistency of the connection between the elastic components. The second type is a split structure. Both the first and third embodiments are split structures. In the first embodiment, the elastic seal 35 and the elastic damping frame body (first cylindrical body) are independently molded components, which can be assembled through the engagement of the snap-fit ​​part and the first snap-fit ​​groove 232. The seal 35 can be selected with different materials or hardness according to different damping requirements, which improves the flexibility and adaptability of the product. In the third embodiment, the first elastic damping component 50 and the second elastic damping component 60 are installed as independent components in the first opening 22 and the second opening 25 of the support assembly 20, respectively. The advantage of this is that the matching elastic material and structural parameters can be flexibly selected according to the vibration characteristics of different positions. For example, the first elastic damping component 50 can be made of a material with higher hardness to cope with the large impact that the front end may receive, while the second elastic damping component 60 can be made of a material with better flexibility to absorb the high-frequency vibration transmitted from the back end, thereby achieving precise suppression of vibration in different parts of the microphone. The split structure also facilitates the replacement and maintenance of individual components. When a certain elastic damping component ages or is damaged, it is not necessary to replace the entire elastic damping frame; only the corresponding component needs to be replaced. All three structures significantly reduce the interference of desktop vibration and environmental noise on the microphone assembly 10 through the deformation of elastic materials, the buffering of air damping, and the synergistic effect of structural components, thereby effectively improving the microphone's sound pickup quality and stability.

[0030] This application also includes a desktop microphone with the aforementioned shockproof structure 200, and the desktop microphone further includes a metal housing 80, such as... Figure 8 , Figure 16 , Figure 18 , Figure 19 , Figure 20 , Figure 21The microphone assembly includes a first part 11 and a second part 12. The first part 11 is placed inside the shock-absorbing structure 200, providing support for the second part 12 and acting as a shock-absorbing mechanism to prevent external vibrations from affecting the microphone assembly 10. The second part 12 is exposed outside the shock-absorbing structure 200 and is used to collect external sound signals. The metal casing 80 is tightly fitted onto the second part 12. Since the metal material can form a relatively complete electromagnetic shielding layer, the installation of the metal casing 80 can effectively reduce the impact of external electromagnetic interference on the microphone assembly 10. The presence of the shielding layer can effectively block some electromagnetic waves from the external environment, preventing these electromagnetic waves from intruding into the working area of ​​the microphone assembly 10. By installing the metal casing 80 on the outside of the microphone, the sound pickup signal is kept in a relatively pure state, avoiding distortion or mixing of other useless signals due to electromagnetic interference, thereby ensuring the accuracy and clarity of the sound information acquired by the microphone assembly 10.

[0031] Furthermore, such as Figure 20 As shown in the diagram, the magnetic field radiation distribution of a microphone using a plastic cover in the prior art is as follows: When the microphone assembly is equipped with a traditional plastic shell 801, since plastic is a non-magnetic material, it cannot bind the magnetic field lines. The magnetic field lines generated by the magnet inside the microphone assembly (shown by the dotted lines in the diagram) will radiate outwards through the plastic cover, forming an open-loop magnetic circuit. This divergence not only means a loss of magnetic energy, but also means that the voice coil inside the microphone assembly is completely exposed to an open electromagnetic environment, making it highly susceptible to intrusion from external stray electromagnetic waves (such as mobile phone signals, power frequency interference, etc.), thereby generating background noise or current noise in the audio signal. Figure 21 As shown, the schematic diagram illustrates the closed magnetic circuit principle inside the microphone assembly when using a metal casing: the magnetic lines of force originally radiating outward inside the microphone assembly (shown by the dotted lines in the diagram) are effectively captured by the side wall 82 of the metal casing 80. The magnetic lines of force are confined within the metal tube wall and guided back to the S pole of the magnet (or the other pole of the magnetic circuit), thus constructing a tight internal closed magnetic loop. When external electromagnetic interference exists, the metal casing 80 also forms a static magnetic shielding layer. External interference magnetic lines of force will preferentially flow along the outer wall of the metal casing 80 and cannot penetrate the casing to enter the internal induction voice coil. This structure significantly reduces the electromagnetic induction noise of the microphone assembly, improves the signal-to-noise ratio, and allows the microphone to maintain a clean sound background even in complex desktop electromagnetic environments (such as near a computer host or monitor). The metal casing and the shockproof structure 200 work together synergistically, enabling the desktop microphone to output clearer, more stable, and higher quality sound during pickup, while being completely unaffected by external noise or physical interference, thus providing users with a professional-grade microphone experience.

[0032] Further, the metal casing 80 has a fifth opening 81, a side wall 82, and a bottom wall 83 connected to the side wall 82. The side wall 82 and the bottom wall 83 form a sleeve. The fifth opening 81 is positioned opposite the bottom wall 83. The metal casing 80 is fitted onto the second part 12 of the microphone assembly through the fifth opening 81. The bottom wall 83 is provided with a plurality of sound-receiving holes 84. These sound-receiving holes 84 are provided to ensure that sound can smoothly enter the interior of the metal casing 80 and be effectively received by the microphone assembly 10. Typically, the sound-receiving holes 84 are evenly distributed on the bottom wall 83, forming one or at least one annular array. When one sound-receiving hole is provided, such as... Figure 18 The mesh cover 85 is directly installed on the top of the microphone assembly 10; a ring array is provided, such as... Figure 19 The microphone holes 84 are evenly distributed on the bottom wall 83; or they are arranged according to the position of the microphone element in the second part 12 of the microphone assembly 10, so as to ensure that the sound can be transmitted to the pickup sensitive area without obstruction, while the side wall 82 and the rest of the bottom wall 83 of the metal shell 80 can still maintain good electromagnetic shielding performance.

[0033] Furthermore, the metal housing 80 can also be integrated with the microphone assembly 10, that is, the metal housing 80 can be welded or integrally formed on the outer periphery of the second part 12 of the microphone assembly, forming a stable structural connection to ensure that the metal housing 80 will not loosen or shift during microphone use, thereby continuously performing its electromagnetic shielding and protection functions. Alternatively, the metal housing 80 can also be connected to the second part 12 of the microphone assembly through detachable methods such as interference fit, threaded connection, or snap-fit ​​structure, which facilitates the individual replacement or maintenance of the metal housing 80. For example, when scratches appear on the surface of the metal housing 80 affecting its appearance, or when the sound hole 84 is blocked by dust or foreign objects affecting the sound reception, it can be easily disassembled for cleaning or replacement without having to treat the entire microphone assembly. The metal housing 80 is made of ferromagnetic metal materials with high magnetic permeability and good mechanical strength, such as pure iron (DT4), low carbon steel (SPCC), or magnetically permeable stainless steel (such as 400 series stainless steel). These materials have excellent magnetic permeability, which can effectively confine magnetic field lines to form a closed magnetic circuit and shield external low-frequency electromagnetic interference.

[0034] Furthermore, such as Figure 18-19As shown, a mesh cover 85 is fitted onto the outer side of the bottom wall 83. This mesh cover 85 is typically made of high-density metal mesh or rigid plastic mesh, and its main function is to provide effective physical protection for the microphone aperture 84 without affecting the normal passage of sound through it. It can prevent dust, water droplets, and small foreign objects from entering the metal housing 80 through the microphone aperture 84 and causing contamination or damage to the microphone assembly 10, thereby ensuring the long-term stable operation and good sound quality of the microphone. It should be noted that the design of the mesh cover 85 also takes acoustic characteristics into account to minimize attenuation and distortion of sound propagation, ensuring that the sensitivity and accuracy of sound pickup are not significantly affected. In terms of installation, the mesh cover 85 is typically fitted to the bottom wall 83 using interference fit, snap-fit ​​connection, or threaded connection to ensure a secure connection and prevent the mesh cover 85 from accidentally falling off during use.

[0035] It should be understood that the application of the present invention is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
