Abstract
Embodiments of this application disclose a wind noise suppression device including a first woven mesh, a second woven mesh, a device housing, and a structural component. The device housing defines a sound pickup hole. The first woven mesh covers the sound pickup hole. The structural component is disposed behind the sound pickup hole. The structural component is coupled to the device housing and forms a cavity. The structural component defines a sound transmission hole. The second woven mesh covers the sound transmission hole. A microphone is disposed at the sound transmission hole. Due to the structural characteristics of all the components the device, wind noise included in an audio signal that is be received by the microphone through the sound transmission hole is effectively reduced.
