[0041] The embodiments of the present application will be further described in conjunction with the drawings and examples. The following detailed description and drawings are provided to illustrate the principles of the present application, but not to limit the scope of the present application, which can be implemented in many different forms, not limited to the specific embodiments disclosed herein, but including all technical solutions falling within the scope of the claims.

[0042] The present application provides these examples is to make the present application and complete, and to the person skilled in the art fully express the scope of the present application. It should be noted that: unless otherwise specified, the relative arrangement of components and steps, the composition of materials, numerical expressions and numerical values set forth in these examples should be interpreted as merely exemplary, and not as limiting.

[0043] It should be noted that, in the description of the present application, unless otherwise specified, the meaning of "a plurality of" is greater than or equal to two; The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0044] In addition, "first", "second" and similar words used in the present application do not represent any order, quantity or importance, but are only used to distinguish different parts. "Vertical" is not strictly vertical, but within the allowable range of error. "Parallel" is not strictly parallel, but within the allowable range of error. "Include" or "contain" and similar words mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0045] When the wind blows towards the microphone, especially directly towards the diaphragm, the wind will directly impact the diaphragm, causing it to vibrate and generate an electrical signal. However, this signal caused by the wind is not a voice signal, but an environmental noise (i.e. wind noise). In addition to the direct impact effect, wind entering the microphone cavity can also form turbulent flow. These turbulent flows are prone to be converted into high-frequency noise, further interfering with the normal voice signal. High-frequency noise not only increases the background noise level, but also distorts the voice signal, making it more difficult to hear clearly.

[0046] To solve the above problems and reduce the direct impact of wind, and avoid the generation of turbulent flow and backflow in the cavity, as shown in Figure 1 and Figure 3 The present application provides a sound collecting device, which comprises a shell structure 10 and a target sound collecting piece 00, the shell structure 10 is internally provided with a containing cavity 11, and a first opening 12 and a second opening 13 are arranged in a spaced and opposite manner, both the first opening 12 and the second opening 13 are in communication with the containing cavity 11;

[0047] The target sound collecting piece 00 is arranged in the containing cavity 11 and is arranged in a spaced manner with the inner wall of the containing cavity 11 to form a through region;

[0048] The first opening 12 and the second opening 13 are respectively arranged on two sides of the through region and communicate with the through region to form the air guide channel 10A.

[0049] It can be understood that, in order to solve the problem of poor sound pickup quality of the traditional microphone in the wind environment, the sound pickup device includes two core components, the shell structure 10 and the target sound pickup piece 00. The sound pickup device can effectively reduce the influence of wind noise on the sound pickup quality of the microphone and reduce the possibility of wind directly impacting the diaphragm of the microphone by optimizing the air flow path.

[0050] The shell structure 10 is internally provided with a space to form a containing cavity 11 for accommodating the target sound pickup piece 00. Two openings are arranged on the shell in a relative and spaced manner and communicate with the containing cavity 11. They allow air (including wind) to enter and exit the containing cavity 11.

[0051] The target sound pickup piece 00 is installed in the containing cavity 11 but maintains a certain distance from the inner wall of the containing cavity 11, so as to form a through region around the target sound pickup piece 00. The two ends of the through region communicate with the first opening 12 and the second opening 13 respectively, allowing air to flow freely, thereby forming an effective air guide channel 10A.

[0052] The structure of the air guide channel 10A is formed by the first opening 12 and the second opening 13 arranged on two sides of the through region and communicating with the through region. For example, when the wind blows towards the sound pickup device, the airflow will enter from the first opening 12, pass through the entire through region, and finally flow out from the second opening 13. This design utilizes the Coanda effect, so that the airflow tends to move along the inner surface of the shell rather than directly impacting the diaphragm of the microphone, thereby effectively reducing the influence of wind noise on the sound pickup quality.

[0053] Since the wind is guided to flow through a specific channel rather than directly impacting the diaphragm of the microphone, it helps to reduce the degree of turbulence of the airflow in the containing cavity 11, thereby reducing the high-frequency noise caused by turbulent flow. Not only does it reduce wind noise, but also because there is a certain gap between the target sound pickup piece 00 and the inner wall of the shell, it further reduces the influence of external vibration on the sound pickup piece through solid conduction, thereby improving the stability of sound pickup and the naturalness of sound.

[0054] The target sound pickup piece 00 is a component that can realize the functions of sound signal capture and conversion. For example, it can be a microphone, especially a single-directional microphone, which can capture sound in a specific direction while minimizing the pickup of noise in other directions. In addition to traditional analog microphones, it can also be a microphone module integrated with digital signal processing functions.

[0055] It should be noted that the target sound receiving part 00 is provided with a first connection point 00A, and the shell structure 10 is provided with a second connection point 10A, and the first connection point 00A and the second connection point 10A can realize electrical connection,

[0056] In order to ensure that the target sound receiving part 00 (such as a microphone) can be effectively connected with external circuit or equipment, a first connection point 00A and a second connection point 10A are usually arranged on the target sound receiving part 00 and the shell structure 10 respectively to realize stable electrical connection and ensure the reliability of signal transmission. The first connection point 00A can adopt various forms such as metal contact, pogo pin, welding point, etc. The second connection point 10A is located inside the shell structure 10 near the position where the target sound receiving part 00 is installed, so as to accurately dock with the first connection point 00A.

[0057] It can be in the form of a socket, a terminal, a pad, etc. to ensure good contact and fixation with the first connection point 00A. It can also provide power or other control signals for the first connection point 00A to transmit the signals received from the first connection point 00A to subsequent processing units (such as amplifiers, converters, etc.).

[0058] In some embodiments, as shown in Figures 1-3 The fixing assembly 20 is arranged in the accommodating cavity 11 and fixedly connected with the target sound receiving part 00 and the inner wall of the accommodating cavity 11.

[0059] The fixing assembly 20 occupies a part of the through region, and the other part of the through region is communicated with the first opening 12 and the second opening 13 to form the air guide channel 10A.

[0060] It can be understood that in order to further optimize the structural design of the sound receiving device and improve its stability and anti-interference ability, the device further comprises a fixing assembly 20

[0061] The fixing assembly 20 is used to provide stable support for the target sound receiving part 00, so as to ensure that it will not produce unnecessary vibration or displacement due to external factors (such as hand touch, device movement, etc.) during use, and can keep high-quality audio capture.

[0062] In addition, by fixedly connecting the target sound receiving part 00 with the inner wall of the accommodating cavity 11, the fixing assembly 20 can also effectively isolate the physical vibration from the outside to the sound receiving part, thereby reducing the so-called "stethoscope effect", which refers to the problem that the vibration caused by friction or collision when holding the device is transmitted to the microphone and converted into noise signals.

[0063] The fixing assembly 20 is arranged inside the accommodating cavity 11 and fixedly connected with the target sound collecting piece 00 and the inner wall of the accommodating cavity 11. The fixing assembly 20 only occupies a part of the space of the through area, so that the through area still has enough space to form the air guiding channel 10A, that is, another part of the through area still communicates with the first opening 12 and the second opening 13, thereby ensuring that the airflow can smoothly pass through the entire accommodating cavity 11, so that the fixing assembly 20 not only ensures the effective fixation of the target sound collecting piece 00, but also does not hinder the function of the air guiding channel 10A, thereby effectively reducing the influence of wind noise.

[0064] The fixing assembly 20 can be a silica gel support. Silica gel material is widely used in shockproof design due to its good elasticity and shock absorption performance. The silica gel support can be designed in a form of surrounding or partially wrapping the target sound collecting piece 00, and absorbing and weakening the external vibration through its elasticity, thereby protecting the sound collecting piece from interference.

[0065] The fixing assembly 20 can also be a spring suspension leg. A suspension structure is constructed by using a spring or other material with high elasticity, and the target sound collecting piece 00 is suspended inside the accommodating cavity 11 by arranging multiple suspension legs on the outer periphery of the target sound collecting piece 00. The vibration from various directions can be effectively isolated, and the sound collecting piece can be used in mobile shooting or sports scenes to ensure the quality of audio capture.

[0066] Therefore, by introducing the fixing assembly 20, the sound collecting device not only enhances the stability of the target sound collecting piece 00 and reduces the noise interference caused by external vibration, but also ingeniously designs the layout of the target sound collecting piece 00 in the accommodating cavity 11, thereby ensuring that the efficiency of the air guiding channel 10A is not affected.

[0067] In some embodiments, as shown in FIG. 1B, the fixing assembly 20 includes at least two connecting pieces 21. The connecting pieces 21 are arranged at the outer periphery of the target sound collecting piece 00, and the first end is fixedly connected with the target sound collecting piece 00, and the second end is fixedly connected with the inner wall of the accommodating cavity 11. Figures 1-3

[0068] The adjacent two connecting pieces 21 form an included angle.

[0069] It can be understood that in order to provide stable support for the target sound collecting piece 00, the fixing assembly structure includes at least two connecting pieces 21 arranged at the outer periphery of the target sound collecting piece 00. The adjacent two connecting pieces 21 form an included angle, which not only helps to uniformly distribute the force from various directions, but also ensures the stability of the entire structure.

[0070] ​The connecting pieces 21 can be multiple, for example, 3, 6, or 8, and are uniformly spaced circumferentially on the outer periphery of the target sound collecting piece 00. The included angle between adjacent connecting pieces 21 is such that any external force acting on the target sound collecting piece 00 can be dispersed in multiple directions. As the number of connecting pieces 21 increases, the force transmission path also increases. For example, when one side is impacted, the force will be distributed to other connecting pieces 21, thereby reducing the pressure on a single connecting point, prolonging the service life and improving the reliability.

[0071] Due to the included angle between the connecting pieces 21, the position and angle of the connecting pieces 21 can be flexibly adjusted according to actual needs, so as to better adapt to the internal space layout of the different accommodating cavities 11. At the same time, it is also helpful to maintain sufficient through areas to ensure the effectiveness of the air guide channel 10A is not affected.

[0072] The connecting pieces 21 can be made of a shock-absorbing material (such as silicone or other elastic materials). Not only can it achieve a mechanical fixing effect, but it can also absorb and weaken the vibration transmitted to the target sound collecting piece 00, further improving the clarity and stability of sound pickup.

[0073] In some embodiments, as shown in Figures 1-3 The fixing assembly 20 includes a surrounding piece 22, which is a tubular structure with two ends communicating. Opposite openings 221 are provided at the two ends, respectively corresponding to the first opening 12 and the second opening 13.

[0074] The target sound collecting piece 00 is arranged in the tubular structure, and the connecting piece 21 is arranged on the outer periphery of the surrounding piece 22, so that the first end of the connecting piece 21 is fixedly connected with the surrounding piece 22. The connecting piece 21 and the surrounding piece 22 are made of an elastic material.

[0075] It can be understood that, in order to further improve the stability of the structure and the shock-absorbing effect, the surrounding assembly further includes a surrounding piece 22, which wraps around the outer periphery of the target sound collecting piece 00 and has openings 221 corresponding to the first opening 12 and the second opening 13. It not only can provide structural support for the target sound collecting piece 00, but also can guide airflow and reduce the influence of wind noise on the target sound collecting piece 00, so that the wind enters the accommodating cavity 11 through the first opening 12, flows through the outer surface of the surrounding piece 22, and flows out from the second opening 13. The connecting piece 21 is located on the outer periphery of the surrounding piece 22, and its first end is fixedly connected with the surrounding piece 22, and its second end is connected with the inner wall of the accommodating cavity 11. Not only does it provide support for the surrounding piece 22, but it also absorbs and disperses external vibrations from different directions.

[0076] The enclosing member 22 and the connecting member 21 can be made of elastic material. The elastic material can achieve high-efficiency shock absorption effect. Common elastic materials include silica gel, rubber, etc., all of which have good elasticity and shock absorption performance, can effectively absorb the vibration energy from the outside, and reduce the vibration amount directly transmitted to the target sound receiving member 00. In addition, the softness of the elastic material allows a certain degree of deformation, which helps to adapt to different installation environments without affecting the overall structural stability of the device.

[0077] The enclosing member 22 and the connecting member 21 made of elastic material work together to provide double protection for the target sound receiving member 00. The enclosing member 22 directly wraps the target sound receiving member 00, playing a role in preliminarily isolating external vibrations; the connecting member 21 further firmly fixes the enclosing member 22 in the accommodating cavity 11, and at the same time absorbs excess vibrations by using its elasticity.

[0078] Moreover, the use of elastic material makes the entire fixing assembly 20 have certain flexibility and adaptability, which can be fine-tuned according to the actual use scenario. For example, in complex outdoor environments, even if a slight collision or uneven surface is encountered, the elastic material can buffer and absorb the impact force, ensuring that the audio quality is not affected.

[0079] In some embodiments, as shown in FIG. 2B, the outer edge of the opening 221 is provided with a circular arc part 2211. Figure 3

[0080] It can be understood that, in order to further reduce wind noise and improve airflow efficiency, the outer edge of the opening 221 is provided with a circular arc part 2211.

[0081] The circular arc part 2211 is arranged at the outer edge of the opening 221, i.e., the edge part of the opening 221 at both ends of the enclosing member 22. The circular arc structure can more smoothly guide the airflow, so that the wind can more naturally enter and exit the air guide channel 10A. Compared with sharp or right-angled edges, the circular arc part 2211 reduces the resistance in the airflow and the possibility of turbulence formation. Moreover, since the circular arc part 2211 can help the air flow along a relatively smooth path, this helps to reduce the noise caused by the sudden change of airflow direction. The structure of the circular arc part 2211 fully utilizes the Coanda effect, i.e., the tendency of fluid to follow the surface of a convex object, so that the wind flows along the outer wall of the cylindrical structure instead of directly impacting the target sound receiving member 00, thereby significantly reducing wind noise. The circular arc part 2211 provides a smooth transition area from the external environment to the inside of the air guide channel 10A, which is beneficial not only for the smooth inflow and outflow of air, but also for reducing additional noise caused by poor air flow.

[0082] In some embodiments, the body of the enclosing member 22 is provided with a hollow part (not shown in the figure).

[0083] ​It can be understood that the hollowed-out part can adopt a closed bubble form or an air hole form penetrating the enclosing member 22. Not only can the air flow path be optimized and the weight be reduced, but also a certain shock absorption effect can be provided.

[0084] The hollowed-out part can be in the form of a closed bubble. The bubble is a completely closed small space that does not directly communicate with the outside world. The bubbles are distributed inside the material of the enclosing member 22, forming a layout similar to a honeycomb structure. It can absorb energy by compression and recovery when subjected to external impact. This characteristic is similar to the tiny air chambers in foam materials, which can effectively disperse and buffer vibrations and reduce the vibration transmitted to the target sound receiving member 00. Although the bubbles are closed, their presence does not significantly weaken the overall structural strength of the enclosing member 22. On the contrary, proper distribution can enhance the material's compression resistance, and due to its lightweight characteristics, the entire device is more portable without losing strength. The presence of bubbles helps break the acoustic resonance cavity that may form, reducing the likelihood of specific frequency sounds repeatedly reflecting and amplifying within the cavity, further reducing unnecessary background noise.

[0085] The hollowed-out part can be in the form of an air hole penetrating the enclosing member 22. The air hole penetrates the side wall of the enclosing member 22, allowing air to flow from one side to the other, forming a channel. Although the main purpose of the penetrating air hole is to guide air flow, it can also to some extent play a role in shock absorption. When external vibrations are transmitted to the enclosing member 22, the material around the air hole will deform slightly, and this deformation can consume part of the vibration energy, acting as a buffer.

[0086] The structure of the air hole can build multidirectional air flow paths, promoting the free entry and exit of air into the containing cavity 11, avoiding additional noise caused by poor air flow. This not only helps to reduce wind noise, but also improves overall ventilation efficiency.

[0087] In some embodiments, as shown in Figures 1-2 the second end of the connecting member 21 is provided with a first matching part 30;

[0088] The inner wall of the containing cavity 11 is provided with a second matching part 40 at a position corresponding to the second end; the first matching part 30 and the second matching part 40 are connected in cooperation.

[0089] It can be understood that in order to ensure that the connecting member 21 can stably fix the enclosing member 22 and the target sound receiving member 00 inside it in the containing cavity 11, and can effectively absorb and disperse external vibrations, the second end of the connecting member 21 is provided with a first matching part 30. Correspondingly, the inner wall of the containing cavity 11 is provided with a second matching part 40 at a position corresponding to the second end; the first matching part 30 and the second matching part 40 are connected in cooperation. Not only does this enhance the stability of the structure, but it also improves the shock absorption effect.

[0090] The first matching part 30 can be used as a connecting point of the connecting piece 21 and the inner wall of the accommodating cavity 11, and can adopt various forms such as buckles, threads, inserts, embedded interfaces, etc. For example, an insert made of elastic material in a columnar shape can provide certain disassembly flexibility while ensuring fastening.

[0091] The first matching part 30 is arranged on the inner wall of the accommodating cavity 11 at a position corresponding to the second end of the connecting piece 21. The second matching part 40 is used to match the first matching part 30 to jointly complete the installation of the fixing assembly 20 and ensure the stability and reliability of the entire structure. The specific structure form can be determined according to the structure of the first matching part 30. For example, if the first matching part 30 is an insert, the second matching part 40 can be a corresponding groove or hole; if the first matching part 30 is a thread, the second matching part 40 needs to match a threaded interface.

[0092] Through the precise matching of the first matching part 30 and the second matching part 40, the connecting piece 21 can firmly fix the enclosing piece 22 in the accommodating cavity 11. In addition, by using an elastic material or a specially designed first matching part 30 (such as a buckle with elasticity), a buffer zone can be formed at the connecting point to effectively absorb and disperse external vibrations from different directions. This helps to reduce the amount of vibration transmitted to the target sound collecting piece 00 and improves the sound pickup quality.

[0093] The use of the first matching part 30 and the second matching part 40 can greatly simplify the installation and disassembly process, allowing users to quickly complete the assembly or maintenance work without tools, thereby improving the convenience of use.

[0094] In some embodiments, as shown in FIG. 1B, the first opening 12 and the second opening 13 are each covered with a corresponding wind shield 50. The wind shield 50 is provided with a plurality of sound inlet holes 51 to form a sound inlet area, and the sound inlet area is not less than the sound collecting area of the target sound collecting piece 00. Figures 1-3

[0095] It can be understood that, in order to further improve the wind noise prevention capability of the sound collecting device and ensure high-quality sound capture, the first opening 12 and the second opening 13 are each covered with a corresponding wind shield 50. The wind shield 50 is provided with a plurality of sound inlet holes 51 to form a sound inlet area, and the sound inlet area is not less than the sound collecting area of the target sound collecting piece 00.

[0096] The wind shield 50 covers the first opening 12 and the second opening 13, which can protect the internal components from the external environment (such as dust, moisture, etc.) and effectively reduce wind noise directly impacting the microphone diaphragm.

[0097] The wind shield 50 is uniformly distributed with a plurality of sound inlet holes 51, which allow sound to pass through while blocking large wind flows from directly entering the wind guide channel 10A.​

[0098] The total area covered by the sound inlet holes 51 on the wind deflector 50 is defined as the sound inlet area, and the area of the sound inlet area is not less than the sound pickup area of the target sound pickup 00. It can not only ensure that the sound signal is captured by the target sound pickup 00 without obstruction, but also avoid sound attenuation or distortion caused by too small sound inlet holes 51.

[0099] The wind deflector 50 can reduce the wind speed and disperse the airflow, prevent the strong wind support from impacting the diaphragm of the target sound pickup 00, thereby significantly reducing the wind noise interference, and the shape, size and density of the sound inlet holes 51 can be adjusted to adapt to various different environmental conditions. For example, in extreme weather conditions, smaller holes can be selected to enhance the windproof effect; and in a relatively calm environment, a larger aperture design can be used to improve the sound transmission rate.

[0100] In some embodiments, a shielding part (not shown in the figure) is arranged in the overlapping area of the wind deflector 50 and the target sound pickup 00 in the direction of the first opening 12 or the second opening 13, and the shielding part shields part of the sound inlet holes 51 in the sound inlet area.

[0101] It can be understood that the target sound pickup 00 is projected in the direction of any one opening, and the overlapping area with the sound inlet area is correspondingly provided with a shielding part to shield the sound inlet holes 51 in the area, which can prevent the wind from directly impacting the diaphragm of the target sound pickup 00, thereby effectively reducing the wind noise. While the sound inlet holes 51 in the non-overlapping area of the other part of the sound inlet area remain in communication with the accommodating cavity 11, the target sound pickup 00 picks up external sound.

[0102] The shielding part is located in the overlapping area of the wind deflector 50 and the target sound pickup 00, that is, a part of the sound inlet holes 51 on the wind deflector 50 is directly covered, and the shielding part can be fixed or detachable. After the shielding part is arranged, for example, the wind noise effect can be more effectively reduced in the low frequency band. And using an adjustable shielding part, the shielding degree can be flexibly adjusted according to the real-time environmental conditions (such as wind speed changes), so that the sound pickup device can maintain good working state in many different environments. For example, in a slight breeze condition, the shielding can be reduced to obtain a more natural sound; and in a strong wind environment, the shielding is increased to protect the audio quality.

[0103] In a second aspect, an electronic device is provided, comprising: a rod body and a sound pickup device;

[0104] The sound collecting device is arranged at the end of the rod body for sound collection. The sound collecting device comprises a shell structure 10 and a target sound collecting part 00. The shell structure 10 is internally provided with a containing cavity 11, and a first opening 12 and a second opening 13 are arranged in a spaced and opposite manner and communicate with the containing cavity 11. The target sound collecting part 00 is arranged in the containing cavity 11 and is arranged in a spaced manner with the inner wall of the containing cavity 11 to form a through region.

[0105] The first opening 12 and the second opening 13 are arranged on both sides of the through region and communicate with the through region to form an air guide channel 10A.

[0106] It can be understood that the rod body serves as a support structure for carrying the sound collecting device, so as to be held by hand or installed on a support such as a tripod, and is suitable for various application scenarios, such as outdoor interviews, sports shooting or conference recording. The sound collecting device is located at one end of the rod body for reducing wind noise and completing sound capture with high quality.

[0107] The sound collecting device comprises a shell structure 10, and a space, i.e., a containing cavity 11, is arranged in the shell for arranging a target sound collecting part 00, such as a microphone.

[0108] The first opening 12 and the second opening 13 are arranged in a spaced and opposite manner on the shell structure 10 and communicate with the containing cavity 11 to form an air guide channel 10A, which helps to reduce the direct impact of wind on the target sound collecting part 00.

[0109] The target sound collecting part 00 is a component capable of realizing sound signal capturing and converting functions, and is used for capturing sound signals and converting them into electrical signals, such as a microphone. The target sound collecting part 00 is arranged in the containing cavity 11 for subsequent processing or transmission, and is kept at a distance from the inner wall of the containing cavity 11, so that a through region is formed around it, which helps to guide the airflow to flow through the through region without directly impacting the target sound collecting part 00. The first opening 12 and the second opening 13 are arranged on both sides of the through region and communicate with the through region, and together form an air guide channel 10A. In the case that wind blows towards the sound collecting device, the airflow will enter from the first opening 12, pass through the entire through region, and finally flow out from the second opening 13. The Coanda effect is utilized to make the airflow tend to move along the inner surface of the shell rather than directly impact the microphone diaphragm, thereby effectively reducing the influence of wind noise on the sound collecting quality.

[0110] Moreover, since the wind is guided to flow through a specific channel rather than directly impacting the diaphragm of the target sound collecting part 00, the degree of turbulence of the airflow in the containing cavity 11 is reduced, thereby reducing the high-frequency noise caused by turbulence. In addition, the air guide channel 10A can also prevent external impurities such as dust and small particles from entering the containing cavity 11, thereby protecting the target sound collecting part 00 from damage.

[0111] Among them, the electronic device can be a professional microphone suitable for professional environments such as broadcasting, television production, recording studio, etc. It can be an interview microphone, in film shooting, news interview or documentary production, the microphone pole held in hand or hung on the support can provide a flexible sound pickup solution. It can be a conference phone device, aiming at the voice capture needs in the conference room or video conference system, it can help to improve the clarity of the speaker's voice, while reducing background noise interference, so that remote participants can clearly hear every detail. It can also be a sports camera microphone. And a drone microphone, which can record natural sound effects or human voice commentary from the aerial perspective during aerial photography, the microphone carried on the drone uses a sound collecting device to cope with the influence of high-altitude wind speed. It can also be a teaching and speaking microphone, in the classroom, lecture hall or large conference room, the speech of the lecturer or speaker needs to be clearly conveyed to each listener. It helps to ensure that the best audio effect can be obtained even in an open space. And it can be a sports earphone, for sports earphones that are often used outdoors, using a sound collecting device can reduce wind noise and provide a clearer call experience during activities such as running and cycling.
