Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, specifically relating to a microphone pop filter and a microphone. Background Technology

[0002] A microphone is a device that converts sound wave signals into electrical signals. Microphones mainly include condenser microphones, dynamic microphones, and electret microphones. Their core principle is to use a diaphragm to sense the vibration of sound waves, which drives an internal magnet or capacitor structure to generate a current signal, which is then amplified by a circuit.

[0003] However, users often experience popping sounds when using microphones. This is primarily caused by the high-speed airflow generated by the plosive sounds of human voices impacting the microphone diaphragm. This high-speed airflow generates strong low-frequency energy, causing the diaphragm to vibrate unstablely, resulting in popping sounds or noise. The popping sounds produced by the microphone are amplified into low-frequency noise, masking the clarity of the original sound source and limiting the microphone's usability in various scenarios. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a microphone pop filter and microphone. By limiting the apertures of the first and second mesh openings, the filter can reduce the direct impact of airflow on the microphone head while ensuring effective sound transmission, thus effectively solving the popping problem.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0006] In a first aspect, the present invention provides a microphone pop filter, comprising a mesh body, wherein the mesh body is provided with a central area and a peripheral area, the peripheral area surrounding the outside of the central area; the mesh body is provided with a plurality of first mesh holes in the central area for dispersing airflow directly towards the microphone head, and a plurality of second mesh holes in the peripheral area, wherein the aperture of the second mesh holes is larger than the aperture of the first mesh holes.

[0007] In some implementations, the aperture of the first mesh is 0.2mm to 0.8mm, and the aperture of the second mesh is 1.0mm to 2.0mm.

[0008] In some implementations, the mesh body has a transition zone between the central area and the peripheral area, and the mesh body has a plurality of third mesh holes in the transition zone. The aperture of the third mesh hole is larger than the aperture of the first mesh hole and smaller than the aperture of the third mesh hole.

[0009] In some implementations, the apertures of the plurality of third meshes vary in a gradient, with the apertures of the plurality of third meshes gradually increasing from the central region to the peripheral region.

[0010] In some implementations, the central area is a circular region with a diameter of 20-30 mm.

[0011] Secondly, this utility model provides a microphone, including a main body and the microphone pop filter described above, wherein the main body includes a microphone head, and the central area of ​​the filter is disposed opposite to the microphone head.

[0012] In some implementations, the mesh is arc-shaped and surrounds the outside of the main body.

[0013] In some implementations, the mesh is detachably connected to the main body.

[0014] In some implementations, the main body is provided with a shock-absorbing frame, and a connecting component is provided between the mesh body and the shock-absorbing frame.

[0015] In some implementations, the connecting component includes a connecting frame disposed on the mesh body; and

[0016] A fixing seat is provided on the connecting frame, and an assembly groove is provided on the fixing seat. The fixing seat is engaged with the shockproof frame at the assembly groove.

[0017] In summary, this utility model has at least the following advantages:

[0018] 1. The microphone pop filter provided by this utility model has a reasonable layout of the first and second mesh holes. When the user uses the pop filter, the sound is transmitted through air vibration. The smaller diameter of the first mesh hole can disperse the airflow in the central area, thereby reducing the direct impact of the airflow generated when the user sings or speaks on the microphone head. At the same time, the larger diameter of the second mesh hole can ensure the transmission of sound vibration in the outer area, that is, outside the first mesh hole. The mesh body can effectively improve the popping problem caused by vocal plosives through the first and second mesh holes. Moreover, the mesh body has a simple structure and is easy to use.

[0019] 2. The microphone provided by this utility model has a microphone pop filter, which can maintain the clarity of the original sound source, reduce the impact of popping sounds on the sound pickup effect, and is suitable for professional scenarios to reduce the time spent on repeated re-recording or post-production repair.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] Please see Figure 1 The microphone pop filter of this invention can effectively solve the problem of microphone popping, enabling the microphone to achieve good sound pickup in scenarios such as KTV, recording and live streaming.

[0029] The microphone pop filter of this utility model includes a mesh body 1, which is preferably, but not limited to, made of metal mesh. The mesh body 1 is provided with a central area 11 and an outer area 12. The outer area 12 surrounds the outside of the central area 11. Specifically, the area of ​​the central area 11 can account for one-fifth of the total area of ​​the mesh body 1. It should be understood that this is not the only limitation on the area of ​​the central area 11. Those skilled in the art can determine the area of ​​the central area 11 according to the position and size of the microphone head.

[0030] The mesh body 1 has multiple first mesh holes 2 in the central area 11 for dispersing airflow to directly hit the microphone head, and multiple second mesh holes 3 in the outer area 12. The aperture of the second mesh holes 3 is larger than that of the first mesh holes 2. Specifically, both the first mesh holes 2 and the second mesh holes 3 can be circular through holes. The multiple first mesh holes 2 are arrayed in the central area 11, and the multiple second mesh holes 3 are arrayed in the outer area 12.

[0031] When a user speaks or sings, the airflow impacts the central area 11 and propagates through the first mesh 2 to the microphone head. The aperture of the first mesh 2 is smaller than that of the second mesh 3. The central area 11 disperses the high-speed airflow through the first mesh 2 to weaken the energy of the airflow impact and reduce the direct impact of the airflow during singing or speaking. The microphone pop filter reduces popping noise. The aperture of the second mesh 3 is larger than that of the first mesh 2 and is located outside the first mesh 2. The outer area 12 retains the function of effective sound propagation through the second mesh 3, especially the penetrating ability of high-frequency sound waves. The sound vibration propagates to the microphone head, and the microphone does not need to reduce sensitivity to solve the popping problem.

[0032] In a preferred embodiment, the aperture of the first mesh 2 is 0.2mm~0.8mm, such as 0.4mm; the aperture of the second mesh 3 is 1.0mm~2.0mm, such as 1.5mm. The reasonable apertures and regular arrangement of the first mesh 2 and the second mesh 3 are conducive to the reasonable dispersion of airflow energy and improves sound fidelity. The microphone pop filter of this utility model can be applied to a variety of scenarios.

[0033] Example 2:

[0034] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 1 In this embodiment, the mesh body 1 has a transition zone 13 between the central area 11 and the outer periphery 12. The mesh body 1 has multiple second mesh openings 3 within the transition zone 13. Specifically, multiple third mesh openings 4 are arrayed and distributed within the transition zone 13. The aperture of the third mesh opening 4 is larger than the aperture of the first mesh opening 2, and smaller than the aperture of the second mesh opening 3. A gradient aperture is formed between the first mesh opening 2, the third mesh opening 4, and the second mesh opening 3, which can effectively optimize the performance of the mesh body 1 in dispersing and blocking airflow, and reduce sound propagation loss.

[0035] In a preferred embodiment, the apertures of the plurality of third mesh openings 4 exhibit a gradient change, gradually increasing from the central region 11 towards the peripheral region 12. Specifically, the apertures of the third mesh openings 4 can gradually increase in lengths of 0.01 mm to 0.05 mm. For example, between two adjacent third mesh openings 4, the aperture of the third mesh opening 4 closer to the peripheral region 12 is 0.03 mm larger than the aperture of the third mesh opening 4 closer to the central region 11. The third mesh openings 4 connect the first mesh openings 2 and the second mesh openings 3, resulting in a reasonable layout and further optimizing the airflow dispersion process.

[0036] In some specific embodiments, the central area 11 is a circular area with a diameter of 20~30mm, such as 26mm. The mesh 1 in the central area 11 can effectively cover the microphone head, further ensuring that the burst airflow is blocked and weakened by the mesh 1 when it propagates to the microphone head, and significantly improving the impact of the direct airflow on the microphone head's sound pickup effect.

The connecting frame 71 is provided with a fixing seat 72, and the fixing seat 72 has an assembly groove 721. The shockproof frame 6 includes an annular seat, and the fixing seat 72 is engaged with the annular seat at the assembly groove 721. The mesh body 1 is assembled through the fixing seat 72, which is simple in structure and convenient in disassembly and assembly.

[0043] In some other specific embodiments, the fixing seat 72 includes an anti-detachment part 722, which is disposed at the opening of the assembly groove 721. The anti-detachment part 722 is an elongated protrusion, and the fixing seat 72 can be restricted from detaching from the ring seat by means of the anti-detachment part 722.
