Description

Technical Field

[0001] The utility model relates to the technical field of microphones, and in particular to a low wind noise sports microphone structure. Background Art

[0002] A microphone is a sound pickup device, which is an energy converter that converts the sound signal transmitted from the sound inlet into an electrical signal. With the rapid development of human-computer interaction technology and the live broadcast industry, microphones as sound pickup devices are widely used in portable electronic products such as mobile phones, headphones, and recording equipment, and are suitable for various indoor and outdoor application scenarios; and the wind noise in the environment has a very prominent impact on the microphone's sound pickup quality, especially the wind noise caused by outdoor scenes such as outdoor sports, which greatly affects the quality of sound transmission and reduces the microphone's sound pickup effect. Therefore, a microphone noise reduction pickup structure is urgently needed to improve the wind noise reduction effect and sound pickup quality. Utility Model Content

[0003] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a low wind-noise sports microphone structure with reasonable structural design, which can reduce wind noise and improve the sound pickup effect.

[0004] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] As a preferred solution of the utility model, the chamfer is a rounded corner, which can reduce the eddy current effect of wind noise at the edge of the step recess, thereby further reducing the influence of wind noise on sound pickup.

[0007] As a preferred solution of the utility model, the edge of the porous mesh cover is provided with an arc flange, which improves the structural strength of the mesh cover. At the same time, the arc flange can reduce the noise reflection and interference caused by the edge effect, which helps to improve the overall sound clarity and sound pickup quality.

[0008] As a preferred solution of the utility model, the porous rubber pad is a silicone pad body, and through holes are evenly distributed on the silicone pad body. While ensuring the normal transmission of sound signals, the good elasticity of the silicone pad body can effectively attenuate and reduce wind noise.

[0009] As a preferred solution of the utility model, the rubber sleeve is a silicone sleeve, which is sleeved on the microphone body and has a certain shock-absorbing effect, thereby protecting the microphone from impact and vibration during movement and extending its service life.

[0010] As a preferred solution of the present invention, an air leakage hole is provided on the diaphragm of the microphone body, which can attenuate the microphone body's ability to collect sound in the low frequency band, thereby reducing wind noise.

[0011] As a preferred solution of the utility model, the diameter of the air leakage hole is 0.2-0.4 mm. Reasonable hole diameter can ensure the sound pickup effect and effectively control wind noise.

[0012] The beneficial effects of the utility model are as follows: the utility model has a reasonable structural design, and the porous mesh cover and the cylinder shell can effectively block the wind noise before it enters the microphone itself, thereby reducing the impact of the wind noise; the chamfer is provided on the step concave edge of the sound receiving panel, which can better buffer and reduce the wind speed, thereby reducing the eddy effect of the wind noise on the step concave edge and reducing the impact of the wind noise on the sound pickup. At the same time, the cooperation of the porous rubber pad and the foam can further attenuate and reduce the wind noise, thereby improving the sound pickup effect.
