Abstract

The invention discloses an active noise reduction method, a noise reduction earphone and a computer readable storage medium. The active noise reduction method comprises the following steps: constructing a preset microphone array based on basic microphones of the noise reduction earphone; collecting an external sound signal through the preset microphone array, and determining a current working mode of the noise reduction earphone after the external sound signal is obtained; positioning the direction of the external sound signal to obtain a positioning result; and calling a preset noise reduction algorithm to perform noise reduction according to the current working mode, the external sound signal and the positioning result. According to the invention, the noise reduction capability of the noise reduction earphone can be improved, no additional microphone is needed, the earphone space is saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of acoustic-electric conversion, in particular to an active noise reduction method, a noise reduction earphone and a computer-readable storage medium. Background technique [0002] With the advancement of technology, the use scenarios of headphones are becoming more and more diverse. However, with the increasing noise pollution in cities, using ordinary earphones outdoors can only cover up the noise by physically reducing noise or increasing the volume. This will not only fail to effectively receive the audio signal inside the earphones, but also cause damage to the user's own hearing. Certain negative effects, so users have higher and higher requirements for earphone noise cancellation. [0003] At present, the commonly used technology for earphone noise elimination is the active noise reduction technology, but most of the existing active noise reduction technologies are based on the combination of multipl...
