DETAILED DESCRIPTION

[0022] The utility model is further described below in combination with examples.

[0023] Please refer to Figures 1-5 The utility model provides a wind noise resistant microphone structure, including base 1, all being equipped with mounting hole 2 in the corner of base 1 four around, base 1 top fixedly connected with noise reduction chip 3, base 1 top front and rear end position all are fixedly connected with limiting column 4, base 1 top fixedly connected with a plurality of mounting screw 5, base 1 rear end fixedly connected with plug 6, base 1 top detachably installed with shell 7, shell 7 bottom is equipped with two limiting hole 8 corresponding with limiting column 4, shell 7 front and rear end all are equipped with two through slot 9, a plurality of through slot 9 bottom all are slidably connected with the threaded sleeve 10 corresponding with mounting screw 5, a plurality of threaded sleeve 10 top all are fixedly connected with runner 11, shell 7 both sides all are equipped with a plurality of evenly distributed heat dissipation hole 12, shell 7 top fixedly connected with condenser microphone 13, shell 7 top fixedly connected with mounting groove 14, and the outer wall of mounting groove 14 is rotatably connected with top cover 15, and top cover 15 top is equipped with a plurality of sound collecting hole 16.

[0024] Further as Figure 3 And Figure 4As shown, it is worth noting that the outer wall of the limiting column 4 is tightly fitted with the inner wall of the limiting hole 8, and the tight fitting of the limiting column 4 and the limiting hole 8 can ensure the accurate positioning of the shell 7 and the base 1, avoid the loosening or misplacement of the components due to vibration, impact or long-term use, help maintain the overall structural stability of the microphone, and reduce the loss of sound quality or performance due to loosening of components during use; and the top of the limiting column 4 is designed in a hemispherical shape, which ensures that the limiting column 4 and the limiting hole 8 can be more smoothly inserted, and the limiting column 4 and the limiting hole 8 cooperate to function as auxiliary positioning, facilitating the installation of the shell 7 by the staff, while enhancing the installation stability of the shell 7.

[0025] Further as shown in Figure 1 , Figure 2 and Figure 4 , it is worth noting that the outer wall of the shell 7 is provided with an aluminum foil shielding layer, which can effectively prevent electromagnetic waves from entering the interior of the microphone, thereby reducing the noise caused by electromagnetic interference and ensuring that the microphone can pick up sound signals more clearly and accurately. By shielding external electromagnetic interference, the audio signal of the microphone will be more pure and will not be affected by electromagnetic noise from the external environment, which can improve the noise reduction capability of the microphone and enable it to focus more on collecting target sound sources without being affected by surrounding electromagnetic noise, thereby achieving more efficient noise reduction effect. The application of the aluminum foil shielding layer increases the overall structural strength of the microphone shell 7, which not only helps to shield electromagnetic waves but also enhances the pressure resistance and physical damage resistance of the microphone shell. The aluminum foil itself has good flexibility and strength, which can improve the durability of the microphone in harsh environments.

[0026] Further as shown in Figure 1 and Figure 4 , it is worth noting that the inner wall of each of the plurality of heat dissipation holes 12 is fixedly connected with a filter screen. When the microphone picks up sound, air flow or wind blowing may generate some noise, which may affect the noise reduction effect of the microphone. By setting a filter screen inside the heat dissipation hole 12, the wind noise caused by air flow can be suppressed to some extent, helping the microphone to focus more on picking up target sound. At the same time, it can prevent dust, dirt, hair or other small particles from entering the interior of the microphone. If these impurities enter the sensitive part of the microphone, they may affect the working performance of the microphone or even damage the internal components. By installing a filter screen on the inner wall of the heat dissipation hole 12, these harmful substances can be effectively prevented from entering the interior of the microphone, thereby improving the long-term stability and durability of the microphone.

[0027] As can be seen from the above working process, by setting the mounting screw 5 and the threaded sleeve 10 to cooperate, the housing 7 and the base 1 can be detachably connected. Users can easily open the microphone housing and maintain the microphone themselves, reducing downtime and high maintenance costs caused by inconvenient maintenance. This flexible disassembly and assembly function makes the microphone more adaptable and sustainable in long-term use, avoiding the need to replace the entire device due to technological advancements.

[0028] Further as Figure 5 As shown, it is worth noting that the inner wall of the top cover 15 has a threaded groove corresponding to the mounting groove 14. Through the threaded connection, the top cover 15 can be installed on top of the condenser microphone 13, ensuring its stability during use. The threaded connection provides stronger mechanical fixing force, preventing the top cover 15 from loosening or falling off due to vibration or external force. This is very important for ensuring the reliability of the microphone during long-term use. At the same time, when it is necessary to clean, maintain or replace internal components of the microphone, the threaded connection provides a convenient disassembly method. Compared with other types of fixing methods, the threaded connection is easier to operate, and users can easily open the microphone for inspection or repair.

[0029] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the outer wall of the top cover 15 is fitted with a windproof sponge cover. In outdoor or windy environments, when the wind blows across the microphone, it may cause unnecessary low-frequency noise, affecting the microphone's sound quality and noise reduction effect. The windproof sponge cover reduces direct contact with the wind by physically blocking and absorbing airflow, thereby significantly reducing the interference of wind noise on recording or sound pickup. At the same time, the sponge material has a certain sound absorption effect, which can absorb high-frequency noise or echoes from the surrounding environment. Especially in indoor or complex environments, it helps the microphone to better isolate background noise, thereby enhancing the noise reduction effect.

[0030] Further as Figure 1 , Figure 2 and Figure 5As shown, it is worth noting that the plurality of sound holes 16 is a concentrically symmetric design, which can ensure that the sound signals received by the microphone from all directions are relatively balanced. Since the sound holes 16 are evenly distributed, the microphone can more accurately pick up sound from different directions, avoiding the over-enhancement or weakening of sound from certain angles, which helps to improve the omnidirectionality or directivity of the microphone and improve the overall sound quality. At the same time, due to the uniform distribution of the plurality of sound holes 16, the distribution of wind noise on the sound holes is also more uniform. Wind noise is usually blown through the microphone from a certain direction. Traditional microphones may be prone to picking up strong wind noise in the direction of the wind. The concentrically symmetric design of the plurality of sound holes 16 allows the disturbance of the wind to be dispersed to different sound holes, thereby reducing the interference of wind noise and improving the performance of the microphone in outdoor or high-wind environments.

[0031] The scheme has the following working process: in actual use, the bottom of the threaded sleeve 10 is sleeved on the top of the installation screw 5 through the auxiliary positioning of the limiting column 4 and the limiting hole 8, and then the threaded sleeve 10 is rotated by rotating the rotating wheel 11, so that the threaded sleeve 10 is rotatably installed on the outer wall of the installation screw 5, thereby installing the shell 7 on the outside of the base 1, and then rotating the top cover 15 to install it on the top of the shell 7, thereby completing the detachable installation of the microphone structure, and using through the plug 6.

[0032] In summary: by setting the installation screw 5 and the threaded sleeve 10 in cooperation, the shell 7 and the base 1 can be detachably connected, the user can easily open the microphone shell, and the microphone can be maintained by the user, reducing the downtime and high maintenance costs caused by inconvenient maintenance. This flexible disassembly function makes the microphone more adaptable and sustainable in long-term use, avoiding the need to replace the entire device due to technological progress; by setting the noise reduction chip 3 and the condenser microphone 13, the noise reduction chip 3 can effectively remove environmental noise, and the condenser microphone 13 can provide higher audio clarity and sensitivity, not only enhancing voice clarity and improving sound quality, but also maintaining stable audio performance in various complex environments.
