Abstract: A headset with the active noise cancellation (ANC) function includes an ANC module, a plurality of speakers, a plurality of power drive circuits, and at least one reference microphone. An output end of any one of the plurality of power drive circuits is connected to at least one of the plurality speakers. The ANC module is connected between at least one reference microphone and input ends of the plurality of power drive circuits. The at least one reference microphone is configured to collect at least one first ambient noise signal. The ANC module is configured to obtain at least one mixed audio signal. The plurality of power drive circuits are configured to perform power amplification on the at least one mixed audio signal based on respective output powers to obtain at least one power-amplified mixed audio signal.

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.
