[0002] As an inseparable electronic product in people's daily life, earphones are closely concerned about their call quality and music playback quality. Environmental noise is an important factor affecting call quality and music playback quality, so the requirements for earphones to reduce environmental noise are getting higher and higher. At present, there are two types of noise reduction technologies for earphones: passive noise reduction and active noise reduction. Among them, active noise reduction refers to installing a noise reduction microphone in the sound cavity to collect external environmental noise, and after algorithm processing, it generates sound waves that are equal to and opposite in phase to the external noise, so as to reduce or even eliminate the noise.

[0003] In existing headphone products, the sound pickup hole is usually set on the side of the headphone shell, especially the outer side of the headphone shell (the side away from the face). When the user is exercising or the external environment is windy, the airflow flows widely through the side of the shell, so it is easy for the airflow to enter the headphone through the sound pickup hole, resulting in excessive wind noise in the headphone, affecting the sound pickup effect of the headphone. In addition, when the wind noise exceeds the computing performance of the noise reduction chip, it will directly affect the active noise reduction effect, sound quality effect, call effect, etc. of the headphone, giving the user a poor experience.

[0004] Therefore, finding a technical solution that can solve the above technical problems has become an important topic studied by technical personnel in this field. Utility Model Content
