Abstract: This application discloses a wind noise suppression device including a first woven mesh (101), a second woven mesh (102), a device housing (103), and a structural component (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 component (104) is disposed at the sound pickup hole (1031). The structural component (104) is connected to the device housing (103) to form a cavity. The structural component (104) is provided with a sound transmission hole (1041). The second woven mesh (102) covers the sound transmission hole (1041). A microphone is disposed at the sound transmission hole (1041). Because structural characteristics of all the components the device, wind noise included in an audio signal received by the microphone through the sound transmission hole (1041) is effectively reduced.
