Abstract

The invention discloses a wind noise-prevention microphone single body and an earphone. The wind noise-prevention microphone single body comprises a microphone body, a high pass filtering circuit, a positive pole terminal, and a negative pole terminal. The positive pole of the microphone body is connected with the positive pole input end of the high pass filtering circuit, and the negative pole of the microphone body is connected with the negative pole input end of the high pass filtering circuit. The positive pole output end of the high pass filtering circuit is connected with the positive pole terminal, and the negative pole output end of the high pass filtering circuit is connected with the negative pole terminal. The wind noise-prevention microphone single body is provided with the high pass filtering circuit, and most of low frequency wind noises are filtered, and the wind noise-prevention effect is effectively improved, and at the same time, the technical scheme is easy to realize, and the cost is low.

Description

technical field [0001] The invention relates to the field of wind noise prevention, and more specifically, the invention relates to a wind noise prevention microphone unit and an earphone provided with a high-pass filter circuit. Background technique [0002] The generation of wind noise is due to the turbulent sound generated by the friction between the earphone structure and the earphone structure when the wind blows, especially the wind noise blowing to the sound inlet hole of the earphone shell. Such wind noise is not only difficult to eliminate with the above-mentioned active noise reduction function, On the contrary, it may be lifted and affect the noise reduction effect. [0003] When an electret condenser microphone (commonly referred to as an ECM microphone in this technical field) is used in the presence of wind or strong airflow, or when the exhalation of the speaker directly impacts the ECM microphone, the ECM microphone will generate noise due to wind pressure f...
