A microphone assembly and microphone Technical Field

[0001] This invention relates to the field of audio equipment technology, and more particularly to a microphone assembly and a microphone. Background Technology

[0002] As the core audio acquisition component of a microphone, the dynamic microphone capsule is extremely sensitive to vibration interference. External vibrations can easily be transmitted to the microphone capsule through the microphone shell, affecting the audio acquisition quality. Therefore, some dynamic microphone capsules are usually equipped with shock mounts.

[0003] Existing microphones typically use external shock mounts, which are attached to the outside of the microphone body, significantly increasing the overall size of the microphone. In scenarios requiring close-up shots, external shock mounts can take up a lot of frame space, affecting the shooting quality. Summary of the Invention

[0004] In view of the above-mentioned existing situation, this application provides a microphone assembly and microphone that can improve the problem of excessively large overall microphone size.

[0005] The present invention provides a microphone assembly and a microphone, comprising: a microphone; a shock absorber connected to the microphone, the shock absorber being elastic; and a housing connected to the shock absorber, wherein a sealed cavity is formed between the shock absorber and the housing, and the housing is used for installation inside the microphone.

[0007] Optionally, the sealed cavity surrounds the circumference of the microphone.

[0008] Optionally, the shock absorber includes an abutment portion and a support portion connected to each other; the abutment portion protrudes from the surface of the support portion, and the abutment portion at least partially protrudes toward the microphone, the abutment portion abutting against the outer wall of the microphone; the support portion is connected to the housing.

[0009] Optionally, the shock absorber includes a plurality of abutting portions, which are evenly distributed along the circumference of the microphone.

[0010] Optionally, the shock absorber further includes a first connecting portion, the support portion extending away from the microphone and connected to the first connecting portion; the first connecting portion partially surrounds the support portion, and the first connecting portion partially is spaced apart from the support portion to form an insertion space; the edge of the housing extends into the insertion space, and the edge of the housing is connected to the first connecting portion.

[0011] Optionally, the housing has a protrusion, the first connecting portion has a groove, the edge of the housing extends into the insertion space, and the protrusion is located in the groove.

[0012] Optionally, the shock absorber further includes a second connecting portion, the support portion extends away from the microphone and is connected to the second connecting portion, the first connecting portion and the second connecting portion are respectively connected to both ends of the support portion; the second connecting portion partially surrounds the support portion, the second connecting portion partially is spaced apart from the support portion, and the edge of the housing is connected to the second connecting portion.

[0013] Optionally, the housing is provided with a plug-in groove, and the second connecting part is provided with a plug-in part, which is inserted into the plug-in groove.

[0014] Optionally, the housing includes a first housing and a second housing connected to each other; the two ends of the first housing are through and the first housing surrounds the shock absorber, and the first housing is provided with the insertion groove; the second housing covers one end of the first housing, and the edge of the second housing abuts against one side of the insertion part, and presses the insertion part against the insertion groove.

[0015] Optionally, the shock-absorbing component is integrally molded.

[0016] The present invention also provides a microphone, which includes the microphone assembly described above.

[0017] The microphone assembly of this invention includes a microphone, a shock absorber, and a housing. The shock absorber is connected to the microphone and is elastic. The housing is connected to the shock absorber, and a sealed cavity is formed between the shock absorber and the housing. The housing is used to install inside the microphone. Therefore, in the microphone assembly provided in this application, the shock absorber can be placed inside the microphone. This built-in shock absorber makes the overall microphone structure more compact and smaller, less likely to interfere with vision. Since the shock absorber is built into the microphone, there is no need to purchase and install an external shock absorber, making it ready to use out of the box and more convenient. Furthermore, a sealed cavity is formed between the shock absorber and the housing. When the microphone housing is subjected to external vibration, the vibration is first transmitted to the housing, then partially transmitted to the sealed cavity and the shock absorber, and finally to the microphone. The air layer in the sealed cavity can initially absorb the vibration energy, achieving buffering. In this way, the microphone's shock absorption not only absorbs vibration energy through elastic deformation of the elastic shock-absorbing component, but also buffers it through the sealed cavity, forming a dual shock absorption effect of "air buffering + elastic shock absorption", which greatly reduces the vibration transmitted to the microphone.

Detailed Implementation

[0032] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0033] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0034] Referring to Figures 1, 2 and 9, this application provides a microphone assembly, which includes a microphone 1, a shock absorber 2 and a housing 3. The shock absorber 2 is connected to the microphone 1 and is elastic. The housing 3 is connected to the shock absorber 2, and a sealed cavity 4 is formed between the shock absorber and the housing 3. The housing 3 is used to be installed inside the microphone.

[0035] Based on the above structure, in the microphone assembly provided in this application, the shock absorber 2 can be placed inside the microphone. This built-in shock absorber 2 makes the overall microphone structure more compact and smaller, less likely to interfere with visual perception. Since the shock absorber is built into the microphone, there is no need to purchase or install an external shock mount, making it ready to use out of the box and more convenient. Furthermore, a sealed cavity 4 is formed between the shock mount and the housing 3. When the microphone housing 3 is subjected to external vibration, the vibration is first transmitted to the housing 3, and then partially transmitted to the sealed cavity 4 and the shock absorber 2, finally reaching the microphone 1. The air layer in the sealed cavity 4 can initially absorb vibration energy, achieving buffering. Thus, the vibration reduction of the microphone 1 not only absorbs vibration energy through the elastic deformation of the elastic shock absorber 2, but also through the buffering effect of the sealed cavity 4, forming a dual vibration reduction effect of "air buffering + elastic shock absorption," significantly reducing the vibration transmitted to the microphone 1.

[0036] In some embodiments, the shock absorber 2 is circumferentially connected to the microphone 1, and the housing 3 is circumferentially connected to the shock absorber 2. Thus, the shock absorber 2 can adequately protect the microphone 1 in the circumferential direction. When the microphone 1 shakes, the inner wall of the shock absorber 2 can tightly adhere to the outer wall of the microphone 1, forming a uniformly distributed constraint force, effectively limiting the radial displacement of the microphone 1. Furthermore, the circumferential structure of the shock absorber 2 ensures balanced force distribution; the inner wall of the shock absorber 2 can abut against the outer wall of the microphone 1, and the large contact area provides a more stable shock absorption effect.

[0037] In some embodiments, the sealing cavity 4 surrounds the circumference of the microphone 1. Thus, the sealing cavity 4 surrounds the circumference of the microphone 1, thereby effectively absorbing vibrations transmitted in multiple directions.

[0038] Referring to Figure 4, in some embodiments, the shock absorber 2 includes an abutment portion 21 and a support portion 22 connected to each other; the abutment portion 21 protrudes from the surface of the support portion 22, and at least partially protrudes towards the microphone 1, abutting against the outer wall of the microphone 1; the support portion 22 is connected to the housing 3. Thus, the abutment portion 21 enhances the sealing effect on the microphone 1, forming a tighter contact surface between the outer wall of the microphone 1 and the abutment portion 21, further limiting the radial movement of the microphone 1 and improving the reliability of sound pickup.

[0039] In some embodiments, the shock absorber 2 includes a plurality of abutment portions 21, which are evenly distributed along the circumference of the microphone 1. Thus, the even arrangement of the plurality of abutment portions 21 can form a uniform supporting force on the microphone 1, and when the microphone 1 shakes, the microphone 1 can receive better shock absorption protection in all directions.

[0040] Referring to Figure 4, in some embodiments, the shock absorber 2 further includes a first connecting portion 23, and the support portion 22 extends away from the microphone 1 and is connected to the first connecting portion 23; the first connecting portion 23 partially surrounds the support portion 22, and the first connecting portion 23 is spaced apart from the support portion 22 to form an insertion space; the edge of the housing 3 extends into the insertion space, and the edge of the housing 3 is connected to the first connecting portion 23. Referring to Figure 9, the support portion 22 and the first connecting portion 23 can together form a bent structure, so when vibration is transmitted from the housing 3, the first connecting portion 23 will deform to absorb vibration energy, thereby reducing the continued transmission of vibration to the support portion 22 and the microphone 1. Specifically, the first connecting portion 23 can form a skirt structure, and the insertion space is also part of the sealed cavity 4. In some examples, the edge of the housing 3 can be connected to the first connecting portion 23 by adhesive.

[0041] Referring to Figures 9 and 11, in some embodiments, the housing 3 is provided with a protrusion 31, and the first connecting portion 23 is provided with a groove. The edge of the housing 3 extends into the insertion space, and the protrusion 31 is located in the groove. Thus, the cooperation between the protrusion 31 and the groove enables the first connecting portion 23 and the housing 3 to form an interlaced structure at the connection point, thereby further improving the sealing performance of the sealing cavity 4.

[0042] Referring to Figure 5, in some embodiments, the shock absorber 2 further includes a second connecting portion 24. The support portion 22 extends away from the microphone 1 and is connected to the second connecting portion 24. The first connecting portion 23 and the second connecting portion 24 are respectively connected to both ends of the support portion 22. The second connecting portion 24 partially surrounds the support portion 22 and is spaced apart from the support portion 22. The edge of the housing 3 is connected to the second connecting portion 24. Referring to Figure 9, the support portion 22 and the second connecting portion 24 can together form a bent structure. When vibration is transmitted from the housing 3, the second connecting portion 24 will deform to absorb the vibration energy, thereby reducing the continued transmission of vibration to the support portion 22 and the microphone 1. Specifically, the second connecting portion 24 can form a skirt structure. In some examples, the edge of the housing 3 can be connected to the second connecting portion 24 by adhesive.

[0043] Referring to Figures 9 and 10, in some embodiments, the housing 3 is provided with a insertion groove 32, and the second connecting part 24 is provided with an insertion part 241, which is inserted into the insertion groove 32. Thus, after the insertion part 241 is inserted into the insertion groove 32, the housing 3 and the second connecting part 24 can fit tightly together, allowing the second connecting part 24 and the housing 3 to form an interlocking structure at the connection point, thereby further improving the sealing performance of the sealing cavity 4.

[0044] Referring to Figures 6, 9, and 10, in some embodiments, the housing 3 includes a first housing 33 and a second housing 34 connected to each other; the first housing 33 has two through-holes and surrounds the shock absorber 2, and the first housing 33 is provided with a insertion groove 32; the second housing 34 covers one end of the first housing 33, and the edge of the second housing 34 abuts against one side of the insertion part 241, and presses the insertion part 241 tightly into the insertion groove 32. Since the insertion part 241 is elastic, the edge of the second housing 34 can squeeze and deform the insertion part 241, thereby further ensuring that the insertion part 241 is firmly inserted into the insertion groove 32, thereby further improving the sealing performance of the sealing cavity 4.

[0045] In some embodiments, the shock absorber 2 is integrally formed. Therefore, the shock absorber 2 does not require connection via parts, resulting in a stable and reliable structure that is conducive to mass production. During installation, simply inserting the microphone 1 into the shock absorber 2 is sufficient, making installation convenient and quick.

[0046] In some embodiments, the shock-absorbing components may be made of elastic materials such as silicone or rubber.

[0047] Referring to Figures 6 and 7, in some examples, the microphone 1 can be divided into a receiving end 11 and a mounting end 12. The microphone assembly also includes a locking member 6, which is respectively inserted through the shock absorber 2. One end of the locking member 6 is threaded to the mounting end 12, and the other end of the locking member 6 presses the bottom shock absorber 2 against the peripheral shock absorber 2. Specifically, the locking member 6 can be a bolt structure, with one end having an external thread and the mounting end 12 having an internal thread. After one end of the locking member 6 is locked to the mounting end 12, the other end of the locking member 6 can press the shock absorber 2 against the mounting end 12, thereby locking the shock absorber 2 and the microphone 1 in the desired position.

[0048] In some embodiments, the shock absorber 2 surrounds the periphery of the microphone 1 and the mounting end 12. Thus, except for the receiving end 11 which needs to pick up sound, the shock absorber can cover the periphery of the microphone 1 and the mounting end 12, absorbing and dispersing external impacts from multiple directions, significantly improving shock resistance. Crucially, when external airflow enters through the microphone's mesh cover, the shock absorber also acts as a buffer layer, reducing the direct impact of airflow from the periphery and bottom on the microphone 1, improving sound quality. Therefore, the shock absorber not only supports and dampens the microphone 1 but also isolates and protects it as much as possible, reducing the impact of airflow on the microphone's sound pickup and ensuring the purity of the sound quality. Furthermore, the built-in shock absorber allows for a more compact and smaller overall microphone structure, while traditional external shock mounts are bulky and can easily interfere with visual perception. With the shock absorber built into the microphone, there is no need to purchase and install an external shock mount, making it more convenient to use.

[0049] Typically, shock mounts provide longitudinal support for the microphone, but when external vibrations are transmitted, the microphone is also prone to radial wobbling. Prolonged exposure to vibration can cause the microphone to droop or tilt, damaging it and resulting in unstable positioning, which negatively impacts sound pickup.

[0050] Referring to Figures 7 and 8, in some embodiments, the microphone assembly may further include a limiting ring 5. The limiting ring 5 is sleeved on the shock absorber 2 and / or the housing 3, and the limiting member partially abuts against the side of the shock absorber 2 opposite to the microphone 1. The limiting member is used to limit the deformation range of the shock absorber 2. Thus, in the circumferential direction of the microphone 1, the setting of the limiting ring 5 effectively limits the shaking of the microphone 1, and also effectively improves the problems of "drooping" and tilting of the microphone 1, ensuring the sound reception quality.

[0051] Referring to Figure 8, in some embodiments, the housing 3 is provided with a mounting position 35, which is recessed toward the shock absorber 2; the limiting ring 5 is located inside the mounting position 35, and the outer wall of the limiting ring 5 is flush with the outer wall of the housing 3. This results in a smoother surface for the microphone assembly, avoiding excessive protrusion of local structures, thus simplifying the internal structure of the microphone and facilitating the routing of internal wiring.

[0052] In some embodiments, the limiting ring 5 is made of metal. In some examples, the limiting ring 5 can be made of a metal material with high rigidity, such as iron or stainless steel. Thus, the high rigidity of the metal limiting ring 5 can provide a precise and stable limiting effect, maintain its original shape and size during long-term use, and has good resistance to deformation, so as to better limit the amplitude of elastic deformation of the shock absorber 2 and limit the shaking of the microphone 1.

[0053] This application also provides a microphone that includes the microphone assembly described above.

[0054] In summary, in the microphone assembly provided in this application, the shock absorber 2 can be housed inside the microphone. This built-in shock absorber 2 makes the overall microphone structure more compact and smaller, less likely to interfere with visual perception. The shock absorber is built into the microphone, eliminating the need for additional purchase and installation of an external shock mount, making it ready to use out of the box and more convenient. Furthermore, a sealed cavity 4 is formed between the shock mount and the housing 3. When the microphone housing 3 is subjected to external vibration, the vibration is first transmitted to the housing 3, then partially transmitted to the sealed cavity 4 and the shock absorber 2, and finally to the microphone 1. The air layer in the sealed cavity 4 can initially absorb vibration energy, achieving buffering. Thus, the vibration reduction of the microphone 1 not only absorbs vibration energy through the elastic deformation of the elastic shock absorber 2, but also through the buffering effect of the sealed cavity 4, forming a dual vibration reduction effect of "air buffering + elastic shock absorption," significantly reducing the vibration transmitted to the microphone 1.
