Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted.

Abstract: This application discloses a method for reducing an occlusion effect of an earphone, and a related apparatus. The method is applied to an earphone having at least one microphone and a speaker. The method includes: detecting occurrence of at least one of the following events: a user speaks and the user is in a motion state; and triggering at least one of the following operations in response to the at least one event: processing the user's sound signal based on the at least one microphone to suppress an occlusion effect of the earphone, and playing an audio by using the speaker, to mask a sound signal in the user's auditory canal. Embodiments of this application can reduce or even eliminate the earphone occlusion effect, to improve user experience.

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.
