Problems solved by technology

At this time, because the external environmental sound signal collected by the microphone includes voice signal and noise signal, and the voice signal and noise signal are played by the earphone at the same time, the user will still be disturbed by the noise signal during the conversation, resulting in poor user experience.

Abstract

The invention discloses an earphone environmental sound monitoring method and the earphone. The method includes: in the listening mode, acquiring an environmental sound signal; extracting a voice signal from the environmental sound signal; outputting the voice signal to an earphone for playback; and / or removing the voice from the environmental sound signal signal to obtain a noise signal; noise reduction processing is performed on the noise signal to generate a noise reduction signal and output it to the earphone for playback.

Description

technical field [0001] The present invention relates to the technical field of sound processing, and more particularly, to an earphone environmental sound monitoring method and an earphone. Background technique [0002] Noise-cancelling earphones can reduce the impact of external environmental sounds on users. The noise-cancelling methods of earphones in the prior art mainly include active noise-cancellation, passive noise-cancellation, and active-noise-cancellation mixed-passive noise-cancellation. [0003] Headphones with active noise cancellation generally have the following two operating modes: [0004] When the earphone is in the noise reduction mode, the earphone uses the noise reduction module to invert the external environmental sound signal collected by the microphone to generate an equivalent inverse reverse sound wave signal which is played by the earphone to offset the external environmental sound signal. In the noise reduction mode, the voice signal contained i...
