Embodiment 1

[0021] refer to figure 1 , shows a flowchart of steps of a noise reduction method according to Embodiment 1 of the present invention.

[0022] The noise reduction method provided by the embodiment of the present invention includes the following steps:

[0023] Step 101: During a call, detect environmental noise parameters of the electronic device.

[0024] During the call, the microphone is called to obtain the environmental noise parameters of the electronic device.

[0025] Step 102: Invoke the optical sensor to acquire the first audio signal about the user when the environmental noise parameter meets the preset condition.

[0026] It should be noted that, in this embodiment, the environmental noise parameters may be parameters such as an environmental signal-to-noise ratio and an environmental noise volume. When the environmental noise parameter is the environmental signal-to-noise ratio, the preset condition is that the environmental signal-to-noise ratio is less than t...

Embodiment 2

[0036] refer to figure 2 , shows a flowchart of steps of a noise reduction method according to Embodiment 2 of the present invention.

[0037] The noise reduction method provided by the embodiment of the present invention includes the following steps:

[0038] Step 201: During a call, detect environmental noise parameters of the electronic device.

[0039] During a call, the microphone is invoked to obtain environmental noise parameters of the electronic device.

[0040] Step 202: When the environmental noise parameter meets the preset condition, acquire at least one of the first vibration information about the user's face and the second vibration information about the user's throat received by the optical sensor.

[0041] When the environmental noise parameters meet the preset conditions, the optical sensor is obtained to receive the first vibration information of the user's face, and the user's first audio signal is determined according to the first vibration information,...

Embodiment 3

[0061] refer to Figure 4 , shows a structural block diagram of an electronic device according to Embodiment 3 of the present invention.

[0062] The electronic device provided by the embodiment of the present invention includes: a detection module 401, configured to detect an environmental noise parameter of the electronic device during a call; a first acquisition module 402, configured to detect when the environmental noise parameter meets a preset condition In this case, call the optical sensor to obtain the first audio signal about the user; the second obtaining module 403 is used to call the microphone to obtain the second audio signal of the user; the processing module 404 is used to obtain the user’s second audio signal according to the first The audio signal performs noise reduction processing on the second audio signal to generate a target audio signal.

[0063] In the embodiment of the present invention, during a call, the environmental noise parameters of the elect...

Abstract

The embodiment of the invention provides a noise reduction method and electronic equipment, and the method comprises the steps: detecting an environment noise parameter of the electronic equipment ina call process; calling an optical sensor to obtain a first audio signal about a user under the condition that the environmental noise parameter meets a preset condition; calling a microphone to obtain a second audio signal of the user; and performing noise reduction processing on the second audio signal according to the first audio signal. to generate ae target audio signal.The relatively accurate first audio signal can be acquired by adopting the optical sensor, and noise reduction is performed on the second audio signal, so that the problem of poor noise reduction effect caused by the problems of inconsistent stacking environment of two microphones or poor isolation of the two microphones and the like in a conventional double-microphone noise reduction scheme is avoided. The call quality is improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a noise reduction method and electronic equipment. Background technique [0002] At present, when an electronic device is talking, it is mainly realized by the cooperation of the first microphone and the second microphone, wherein the first microphone acquires the target voice, and the second microphone picks up the noise. And the first microphone and the second microphone need to keep a certain distance. Due to the limitation of the size of the whole machine, the first microphone often cannot obtain enough amplitude difference for the target voice, which will cause voice transmission due to excessive suppression. When the volume is too low. In addition, when the second microphone is limited in stacking, resulting in inconsistent bandwidth or inconsistent sealing state, the call noise reduction capability will be greatly affected, affecting the user's call quality. ...
