Description

Technical Field

[0001] This utility model relates to the field of microphone accessories technology, specifically to a microphone clip with a built-in multiple shock absorption system. Background Technology

[0002] In professional audio recording scenarios, microphone recording quality is easily affected by external vibrations. Common sources of vibration include: slight shaking of the microphone stand (such as from human touch or ground vibration), mechanical vibration of surrounding equipment (such as vibration transmitted from mixing consoles or speakers), and stand resonance caused by airflow disturbances. These vibrations are transmitted to the microphone body through the microphone clip, causing the microphone diaphragm to displace additionally with the vibration, ultimately resulting in low-frequency noise, distortion, and other problems in the recording, severely affecting audio quality.

[0003] The existing microphone clip design has the following drawbacks: Simple shock absorption structure: Most clips rely on a single rubber pad for shock absorption, which can only weaken vibrations in a specific frequency band and cannot cover the entire frequency band of 100-2000Hz that the microphone is sensitive to, so the shock absorption effect is limited; Poor material compatibility: When using homogeneous materials or combinations of materials with small density differences, vibration energy is easily transmitted continuously along the materials, making it difficult to reduce the energy through reflection by "medium abrupt change"; In addition, existing clips do not take into account the problem of "cavity resonance" - some vibration damping designs with cavity structures can cause cavity resonance in certain frequency bands, which amplifies the vibration and further degrades the recording quality.

[0004] Therefore, there is an urgent need to design a microphone clip that combines full-band vibration reduction and stability to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the weak shock absorption effect of existing microphone clips, the purpose of this utility model is to provide a microphone clip with a built-in multi-vibration damping system, which can effectively reduce vibration across the entire frequency band, while also having the functions of multi-size compatibility and stable angle adjustment, thereby improving the recording quality of the microphone.

[0006] To achieve the above objectives, this utility model provides a microphone clip with a built-in multi-vibration damping system, including a clamping assembly, a connecting bracket assembly, and a vibration damping assembly. The vibration damping assembly includes, in sequence along the vibration transmission direction, a first vibration damping plate, a damping sleeve, a vibration damping and sound-absorbing felt, a vibration damping washer, a second vibration damping plate, and a connecting nut. The first vibration damping plate, the damping sleeve, the vibration damping and sound-absorbing felt, the vibration damping washer, the second vibration damping plate, and the connecting nut are fixed through the connecting assembly to form a multi-layer nested structure, thereby achieving multiple reductions in vibration energy.

[0007] Furthermore, the top of the first damping pressure plate is a raised end, and the raised end is provided with a connecting hole for connecting with the connecting bracket assembly using screws. The bottom of the first damping pressure plate is a flat end, and its end face is used to cooperate with the upper opening of the damping sleeve.

[0008] Furthermore, the top of the second damping pressure plate is a flat end, which is used to cooperate with the bottom opening of the damping sleeve, and the bottom of the second damping pressure plate is a spiral protrusion, which is used to cooperate with the connecting nut for connection.

[0009] Furthermore, the damping sleeve is a silicone spring-like structure with a spiral shape on the outside and a hollow spiral shape on the inside. It forms a sealed cavity for placing the damping and sound-absorbing felt and the damping ring washer by cooperating with the edges of the first damping pressure plate and the second damping pressure plate. The sealed cavity is located in the spiral hollow channel of the rubber damping sleeve, and the spiral hollow channel forms an "air spring" structure.

[0010] Furthermore, the damping and sound-absorbing felt is connected to the damping ring washer and disposed inside the hollow part of the damping sleeve.

[0011] Furthermore, the shock-absorbing and sound-absorbing felt is a high-density wool felt structure with a porous surface; the surface of the shock-absorbing and sound-absorbing felt is provided with corrugated embossing.

[0012] Furthermore, the damping washer is made of polyurethane.

[0013] Furthermore, the connecting nut is a composite structure formed by a plastic jacket and a brass nut. The brass nut is embedded inside the plastic jacket, and the outer circumferential surface of the brass nut is provided with straight knurling and is tightly connected to the plastic jacket.

[0014] Furthermore, the clamping assembly has a top for clamping the microphone and a bottom for connecting to the connecting bracket assembly.

[0015] Furthermore, the connecting bracket assembly includes a lower bracket body and a fixed pivot. The lower bracket body and the clamping assembly are connected through the fixed pivot to achieve angle adjustment of the microphone clip assembly.

[0016] The microphone clip with a built-in multi-vibration damping system provided by this utility model effectively weakens vibrations across the entire frequency band through a composite damping structure formed by heterogeneous material reflection, damping consumption, cavity buffering, and sound absorption. It also features multi-size compatibility and stable angle adjustment, thereby improving the microphone's recording quality. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] In view of the weak shock absorption effect of existing microphone clips, the purpose of this utility model is to provide a microphone clip with a built-in multi-vibration damping system. It achieves effective reduction of vibration across the entire frequency band through a composite damping structure of "heterogeneous material reflection + damping consumption + cavity buffering + sound absorption". At the same time, it has the functions of multi-size adaptation and stable angle adjustment, thereby improving the recording quality of the microphone.

[0022] See Figure 1 and Figure 2 The microphone clip with a built-in multiple shock absorption system provided by this utility model includes a clamping component, a connecting bracket component, and a shock absorption component.

[0023] The clamping assembly 1 has a top for clamping the microphone and a bottom for connecting to the connecting bracket assembly.

[0024] The clamping assembly in this solution is integrally molded using an injection mold, ensuring the reliability of the clamping assembly 1 structure. Meanwhile, the clamping part of the clamping assembly 1 is made of a high-strength, high-tensile, and high-elasticity polyester structure, ensuring the microphone is clamped securely while protecting the microphone surface from scratches and also providing some shock absorption.

[0025] The connecting bracket assembly is connected to the clamping assembly 1. The connecting bracket assembly includes a lower bracket body 2 and a fixed rotating shaft 4. The lower bracket body 2 has an installation area in the middle and through connecting holes at both ends. The bottom of the clamping assembly 1 is placed in the installation area of ​​the lower bracket body 2, and the connecting holes at the bottom of the clamping assembly 1 are aligned with the connecting holes of the lower bracket body 2. The connection is made through the fixed rotating shaft 4 and secured with the locking assembly 3.

[0026] This solution connects the clamping component 1 to the connecting bracket component body via a fixed pivot 4 and a locking component 3, thereby enabling the adjustment of the microphone clip component's angle.

[0027] The connecting bracket assembly is preferably constructed of reinforced plastic and fiberglass. One end of the bracket is connected to the clamping assembly 1 via a fixed pivot 4 to adjust the angle of the microphone clip assembly. At the same time, both the fixed pivot 3 and the lower bracket body 2 are provided with slit positioning to ensure that the locking assembly 3 will not loosen due to frequent adjustment of the microphone angle, and to ensure that the microphone will not loosen or shift during use.

[0028] Furthermore, the end face of the mounting area in the middle of the connecting bracket assembly is provided with a connecting hole, which is used to connect with the shock absorption assembly by engaging the first screw 6.

[0029] The vibration damping assembly is used to dampen the microphone clip. It consists of a first damping pressure plate 7, a damping sleeve 5, a damping and sound-absorbing felt 9, a damping washer 11, a second damping pressure plate 8, and a connecting nut 12 arranged sequentially along the vibration transmission direction. Each component is fixed by a second screw 10, forming a multi-layer nested structure, which forms a multi-layer damping structure along the vibration transmission direction, thereby achieving multiple reductions in vibration energy.

[0030] The top of the first damping plate 7 is a raised end, and the raised end is provided with a connecting hole for connecting with the first screw 6 in conjunction with the connecting bracket assembly. The bottom of the first damping plate 7 is a flat end, and its end face is used to cooperate with the upper opening of the damping sleeve 5.

[0031] The top of the second damping pressure plate 8 is a flat end, which is used to cooperate with the bottom opening of the damping sleeve 5. The bottom of the second damping pressure plate 8 is a spiral protrusion, which is used to cooperate with the connecting nut 12 for connection.

[0032] The first damping plate 7 and the second damping plate 8 are preferably made of aluminum alloy, which has high strength and rigidity, and serves as the support and connection hub of the damping structure.

[0033] In this scheme, the damping sleeve 5 is preferably a spring-shaped structure made of special silicone rubber. Its outer surface is helical and its inner surface is hollow helical. It forms a sealed cavity by cooperating with the edges of the first damping plate 7 and the second damping plate 8.

[0034] The sealed cavity is located within the spiral hollow channel of the rubber damping sleeve 5. This spiral hollow channel forms an "air spring," utilizing the "air spring effect" to buffer vibration impacts. When vibration is transmitted, the rubber damping sleeve 5 dissipates vibration energy through compression deformation, while the spiral structure extends the vibration transmission path. This utilizes the "air spring effect" to buffer vibration impacts.

[0035] The damping and sound-absorbing felt 9 and the damping ring washer 11 are connected and installed inside the hollow cavity of the damping sleeve 5. This effectively eliminates the "cavity resonance" caused by the sealed cavity structure and absorbs some of the vibration waves.

[0036] The vibration-damping and sound-absorbing felt 9 in this solution is preferably high-density wool felt, whose porous structure can absorb vibration waves, especially showing excellent absorption effect for vibrations in the 100-2000Hz frequency band that microphones are sensitive to. At the same time, the corrugated embossed design on the surface can effectively avoid cavity resonance; The shock-absorbing washer 11 is preferably made of polyurethane, which has high resilience and can further buffer high-frequency micro-vibrations, avoiding rigid transmission of the screw.

[0037] Furthermore, the connecting nut 12 in this solution preferably adopts a composite structure of plastic and brass, which utilizes the high density difference between the two materials to reflect a large amount of vibration energy at the interface, reducing the transmission to the microphone.

[0038] Specifically, the brass nut is embedded inside the plastic jacket, and the outer circumference of the brass nut is decorated with straight knurling. The two are tightly connected by injection molding and bonding.

[0039] The damping sleeve 5, the sound-absorbing and vibration-damping felt 9, the vibration-damping washer 11, the second vibration-damping pressure plate 8, and the connecting nut 12 are nested together and then fixedly connected with the second screw 10 to form the core of this vibration damping system.

[0040] When vibration is transmitted from the connecting nut 12, it is first reflected and reduced due to the abrupt change in density of the plastic-brass composite structure. The remaining vibration is then buffered by the second damping plate 8, the damping washer 11, absorbed by the damping and sound-absorbing felt 9, and damped by the rubber damping sleeve 5. Finally, it is transmitted to the connecting bracket assembly through the first damping plate 7. Only a small amount of vibration energy is transmitted to the clamping assembly 1, thus achieving full-frequency vibration reduction.

[0041] The microphone clip with a built-in multiple shock absorption system constructed by the above scheme is illustrated in the following example to show its working process in a specific application. It should be noted that the following working process is only an example and does not constitute a limitation on this scheme.

[0042] This design sequentially includes a first damping plate 7, a damping sleeve 5, a damping and sound-absorbing felt 9, a damping washer 11, a second damping plate 8, and a connecting nut 12 below the connecting bracket assembly. When vibration is transmitted, it is first reflected and reduced due to the density abrupt change in the composite structure of plastic and brass after entering through the connecting nut 12. The remaining vibration is then buffered by the damping washer 11 (secondary dielectric abrupt change), absorbed by the second damping plate 8 (tertiary dielectric abrupt change), damped by the damping and sound-absorbing felt 9, and damped by the rubber damping sleeve 5 (tertiary dielectric abrupt change + damping loss + cavity buffering). Finally, it is transmitted through the first damping plate (fourth dielectric abrupt change) to the microphone clip lower bracket assembly (fifth dielectric abrupt change). Ultimately, only a small amount of vibration energy is transmitted to the clamping assembly 1, achieving full-frequency vibration damping. This protects the microphone from vibration interference and improves recording quality.

[0043] The material density of the above-mentioned damping system components exhibits a stepped distribution along the vibration transmission direction: "high-low-medium-low-high-low". Damping plate A (2.7 g / cm³) 3 → Rubber damping sleeve (1.2g / cm) 3 → Vibration-damping and sound-absorbing felt (0.4g / cm) 3 → Shock-absorbing washer (0.4g / cm) 3 → Shock-absorbing pressure plate B (2.7g / cm) 3 → Connecting nut (plastic sleeve 1.2g / cm) 3 Brass nuts 8.5g / cm 3 Vibrational energy is reduced through multiple reflections.

[0044] The microphone clip with a built-in multi-vibration damping system described in this design has the following advantages compared to existing technologies: Excellent vibration reduction effect across the entire frequency band: Through a quadruple vibration reduction mechanism of "heterogeneous material reflection + damping consumption + cavity buffering + sound absorption", it effectively eliminates recording noise caused by vibration and improves audio clarity.

[0045] Stable and reliable angle adjustment: The free-stop angle adjustment can precisely fix the recording angle without angle deviation during use, meeting the recording needs of different scenarios.

[0046] High safety: The microphone clip, made of high-strength thermoplastic polyester elastomer material, ensures clamping stability and avoids scratching the microphone surface; the material meets safety standards and can directly contact the microphone shell.

[0047] Good structural durability: All components are made of wear-resistant and anti-aging materials, making them suitable for long-term professional use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
