Description

Technical Field

[0001] The utility model relates to the field of earphones, in particular to an anti-wind noise earphone. Background Art

[0002] When using headphones outdoors, due to the influence of wind, a lot of wind noise will be generated during calls, making it difficult for the other party to hear what is being said, seriously affecting the user experience. The wind noise of headphones is a problem that is difficult to completely solve. How is wind noise generated? Generally speaking, noise is generated by other sound sources in the background of the sound source. But wind noise is different. Wind noise is not simply noise that humans hear in a windy environment, but is generated by air turbulence near the microphone. Therefore, the source of wind noise is near the microphone.

[0003] Anti-wind noise refers to the elimination of wind noise. Due to the physical characteristics of the Coanda effect and the wall effect, the tendency of fluids to flow along the surface of protruding objects toward the surrounding low-pressure belt, so all kinds of noise reduction schemes are designed to reduce wind noise. Wind noise is the pseudo-sound formed by the turbulence of air flow on the surface of the microphone. It can be reduced by physical or algorithmic methods. Physical methods are mostly through protecting the pickup (microphone), wrapping it or attenuating, diverting or avoiding the airflow, etc., and physical methods are currently the most important means of reducing wind noise. The test standard for anti-wind noise headphones uses wind blowing from two directions relative to the human head, from the front and side, to determine the degree of influence of wind noise on the air entering the headphone pickup hole.

[0004] When wind noise enters the sound inlet of the microphone unit through the earphone pickup hole channel, and the air cannot be effectively discharged from the cavity, the wind pressure of the air in the cavity increases, thereby affecting the sound pickup effect of the microphone and causing the call quality of the earphone to deteriorate.

[0005] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content
