WIND NOISE PREVENTION DEVICE, AND DESIGN METHOD THEREFOR

WIPO Patent Application WO/2022/135243

A1

A wind noise prevention device, which relates to the field of wind noise handling, and solves the problem of how to reduce wind noise caused by the impact of a turbulent air flow on a device. The wind noise prevention device (100) comprises a first woven mesh (101), a second woven mesh (102), a device housing (103), and a structural member (104). The device housing (103) is provided with a sound pickup hole (1031). The first woven mesh (101) covers the sound pickup hole (1031). The structural member (104) is arranged at the sound pickup hole (1031). The structural member (104) is connected to the device housing (103) to form a cavity. The structural member (104) is provided with a sound conducting hole (1041). The second woven mesh (102) covers the sound conducting hole (1041). A microphone is arranged at the sound conducting hole (1041). Owing to the structural characteristics of the sound pickup hole (1031), the first woven mesh (101), the structural member (104) and the second woven mesh (102), the energy of wind noise can be suppressed, thereby effectively reducing the wind noise contained in audio signals which are received by the microphone from the sound conducting hole (1041).
