Embodiment Construction

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the embodiments of the present application.

[0058] Existing Bluetooth headsets, such as TWS (True Wireless Stereo) Bluetooth headsets, usually have three microphones, a feedforward microphone, a call microphone and a feedback microphone. The feedforward microphone and the call microphone are outside the headset, and the feedback microphone In the ear when in use. When making a call in a scene with wind, since the pickup holes of the f...

Abstract

The invention provides an earphone noise reduction method, earphone equipment and a computer readable storage medium, and relates to the technical field of earphones. The method comprises the following steps: calculating a first signal in a feedforward microphone according to an adaptive filter to obtain an estimated signal of wind noise; and performing wind noise reduction on the second signal in the feedback microphone according to the estimation signal to obtain a target signal for output. According to the invention, when the earphone device starts the active noise reduction mode, in a wind noise scene, the sound signal in the feed-forward microphone is used as the reference signal of the adaptive filter, so that the estimation signal of wind noise is obtained, and the signal in the feedback microphone is used as the input signal of adaptive filtering according to the estimation signal, so that the noise reduction effect is improved. According to the technical scheme, wind noise reduction is carried out on the signals collected in the feedback microphone, when the earphone equipment starts the active noise reduction mode, wind noise in a scene can be effectively suppressed, so that noise reduction is carried out on environment noise and wind noise, and the noise reduction effect and the call effect in the earphone equipment are effectively optimized.

Description

technical field [0001] The present application relates to the technical field of earphones, and in particular, to a noise reduction method for earphones, an earphone device and a computer-readable storage medium. Background technique [0002] The existing Bluetooth headset usually has three microphones, wherein the feedback microphone is placed in the ear, and the sound pickup holes of the feedforward microphone and the call microphone are located on the outer surface of the headset. Therefore, when talking in a scene with wind noise, the sound pickup holes located on the outside are easily blown by the wind directly, forming turbulence and destroying the voice signal. Therefore, in the case of wind noise, the feedback microphone signal is usually selected as the output. [0003] However, in the prior art, when the ANC (Active Noise Cancellation, active noise reduction) mode is turned on in the earphone, the feedback microphone collects the signal played in the speaker, and...
