Embodiment 1

[0040] figure 1 It is a flow chart of an earphone noise reduction method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of adjusting the earphone noise reduction depth when the environment changes. The method can be executed by an earphone noise reduction device, specifically including Follow the steps below:

[0041] S110. In response to the switching operation of the noise reduction mode by the user, perform environmental noise monitoring and collect environmental sound.

[0042] Among them, the noise reduction mode can be a normal noise reduction mode and a deep noise reduction mode,

[0043] In normal noise reduction mode, the earphones filter out mid-, low-frequency, and mid-to-low-loudness ambient noise, and in deep noise-cancellation mode, the earphones filter out high-frequency, mid-to-high-loudness ambient noise. Exemplarily, the user can operate the Bluetooth headset by single-clicking, double-clicking, or long-pre...

Embodiment 2

[0056] figure 2 The flow chart of an earphone noise reduction method provided in Embodiment 2 of the present invention is refined on the basis of the above-mentioned embodiments to confirm the depth of earphone noise reduction. The method specifically includes the following steps:

[0057] S210. In response to the switching operation of the noise reduction mode by the user, perform environmental noise monitoring and collect environmental sound.

[0058] Specifically, the user turns on the deep noise reduction function in the application client, and at the same time the Bluetooth headset turns on the noise reduction function, the client application establishes a connection with the Bluetooth headset, and the headset feed-forward microphone collects the ambient sound of the user's environment.

[0059] S220. Remove the environmental sound sample data with the highest value and the lowest value among the preset number of environmental sound sample data, and perform mean value pr...

Embodiment 3

[0074] image 3 It is a schematic diagram of the functional modules of an earphone noise reduction device in Embodiment 3 of the present invention. The embodiment of the present invention provides an earphone noise reduction device, including: a noise collection module 310, a noise reduction depth determination module 320, and a noise reduction mode adjustment module 330.

[0075] Among them, the noise collection module 310 is used to monitor the environmental noise and collect the current environmental sound in response to the user's switching operation of the noise reduction mode; Matching noise reduction depth; noise reduction mode adjustment module 330, configured to adjust the noise reduction mode of the earphone to the target noise reduction mode according to the noise reduction depth and the current noise reduction mode, so as to achieve noise reduction.

[0076] In the technical solution of this embodiment, the noise collection module responds to the user's noise redu...

Abstract

The embodiment of the invention discloses an earphone noise reduction method and device, an earphone and a medium. The earphone noise reduction method comprises the steps that in response to a noise reduction mode switching operation of a user, environmental noise monitoring is carried out, and environmental sound is collected; a noise reduction depth matched with the environment sound is determined according to the environment sound; and according to the noise reduction depth and the current noise reduction mode, the noise reduction mode of the earphone is adjusting into a target noise reduction mode so as to realize noise reduction. According to the embodiment of the invention, the technical problem that the operation of manually adjusting the noise reduction mode through the client application is inconvenient in the prior art is solved, and the noise reduction earphone can automatically switch the noise reduction mode under the condition of environmental change, so that a user can use the noise reduction earphone more conveniently, and the user experience effect is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of signal processing, and in particular, to a noise reduction method and device for earphones, earphones and media. Background technique [0002] The development of urbanization is accompanied by more and more serious environmental pollution, and noise is one of the common environmental pollution. Environmental noise mainly comes from traffic, industry, construction and social aspects. Users can reduce environmental noise by wearing noise-canceling headphones to protect the user's hearing. [0003] The currently used headphone noise reduction method usually uses a combination of a feedforward microphone and a feedback microphone to generate a sound wave that is opposite in phase to the ambient sound and has the same frequency and amplitude, neutralizes the generated sound wave and the sound wave of the ambient sound, and cancels the sound wave transmitted to the ambient sound , to...
