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...
