Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0021] In the prior art, since the feed-forward microphone is directly exposed to the external environment, it is easily disturbed by the external environment, especially wind noise. This causes the feedforward noise reduction process to be greatly affected by wind noise, resulting in poor noise reduction effects. For this technical problem, the embo...

Abstract

The embodiment of the invention provides a wind noise prevention method, an earphone and a storage medium. The method comprises the following steps: acquiring a first noise signal and a second noise signal respectively acquired by a feed-forward microphone and a reference microphone of the earphone, wherein a windward side of the reference microphone is covered with a windproof layer; determininga wind noise signal included in the first noise signal according to a difference between the first noise signal and the second noise signal; and stopping the feed-forward noise reduction processing carried out on a useful signal output by a speaker in the earphone when the wind noise signal does not satisfy a feed-forward noise reduction condition. According to the wind noise prevention method provided by the embodiment of the invention, the wind noise signal included in the first noise signal can be determined; when the wind noise signal does not meet the feed-forward noise reduction condition, a feed-forward noise reduction function of the earphone can be stopped, so that the influence of the wind noise signal on the feed-forward noise reduction function of the earphone is avoided, thusthe auditory experience of users is improved.

Description

technical field [0001] The present application relates to the technical field of noise reduction, in particular to a method for preventing wind noise, earphones and storage media. Background technique [0002] The basic principle of feed-forward noise reduction is that the feed-forward microphone set outside the earphone collects the environmental noise signal, and performs inversion processing on the environmental noise through the noise reduction filter, and broadcasts the equivalent inversion of the environmental noise signal through the speaker inside the earphone. Phase noise reduction signal to cancel the environmental noise signal. [0003] Since the feed-forward microphone is directly exposed to the external environment, it is susceptible to interference from the external environment, especially wind noise. This causes the feedforward noise reduction process to be greatly affected by wind noise, resulting in poor noise reduction effects. Contents of the invention ...
