Embodiment 1

[0021] figure 1 It is an implementation flow chart of the earphone noise reduction method provided by the embodiment of the present invention, and is described in detail as follows:

[0022] In step S101, the frequency of the current noise is acquired;

[0023] In step S102, it is judged whether the frequency is in a pre-configured frequency range, and the frequency range includes frequencies heard by the user personally;

[0024] Before step S101, or before step S102, a frequency range is configured.

[0025] Frequency ranges can be stored locally on the device, or on a web server.

[0026] When stored in the network server, by receiving the identification information input by the user, the frequency range corresponding to the identification information can be remotely called out from the network server according to the identification information.

[0027] Among them, the identification information includes but not limited to the user's ID number, membership number, finger...

Embodiment 2

[0033] figure 2 It is the implementation flow chart of configuring the frequency range provided by the embodiment of the present invention, which is described in detail as follows:

[0034] In step S201, sounds of different frequencies are played, and the sounds of different frequencies include low-frequency, intermediate-frequency, and high-frequency sounds;

[0035] In step S202, recording the frequencies heard by the user in the sounds of different frequencies;

[0036] Through the recording control, when the confirmation information manually input by the user is recorded, the frequency of the currently played sound is taken as the frequency heard by the user.

[0037] In step S203, a frequency range is configured according to the heard frequency.

[0038] Sort the heard frequencies according to the frequency, select the lowest frequency and the highest frequency to form a frequency range, so that the frequency range includes the frequencies heard by the user

Embodiment 3

[0041] image 3 It is the first implementation flowchart of step S103 of the headphone noise reduction method provided by the embodiment of the present invention, and is described in detail as follows:

[0042] In step S301, when the frequency is in a preconfigured frequency range, it is judged whether the frequency belongs to low frequency;

[0043] In step S302, when the frequency belongs to low frequency, call the active noise reduction mode;

[0044] In step S303, the current noise reduction mode is controlled to be the active noise reduction mode, and the noise reduction level corresponding to the frequency is set.

[0045] Wherein, the noise reduction level corresponding to the frequency is set, specifically:

[0046] When the frequency is less than the preset low frequency threshold, the noise reduction level corresponding to the frequency is set to be high, and when the frequency is not less than the preset low frequency threshold, the noise reduction level correspon...

Abstract

The invention is applicable to the field of earphone noise reduction and provides an earphone noise reduction method and device. The earphone noise reduction method includes: acquiring current noise frequency; judging whether the frequency is in the preconfigured frequency range, wherein the frequency range comprises the frequency heard by a user; on yes judgment, calling the noise reduction mode and setting the noise reduction level that the frequency corresponds to according to the frequency. The earphone noise reduction method and device solves the problem in the existing earphone noise reduction mode that preferable noise reduction mode selection and different noise reduction level setting cannot be achieved according to the sound frequency heard by the user, and noise cannot be eliminated effectively. Under the condition that an earphone is used normally, the current noise reduction mode can be switched to the preferable noise reduction mode quickly, the electric quantity of the earphone is saved, and the noise reduction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of earphone noise reduction, and in particular relates to an earphone noise reduction method and device. Background technique [0002] Noise pollution is one of the four major pollutions recognized internationally. With the development of urbanization and technological progress, noise pollution has become more and more serious. When the headset is playing audio, it can reduce noise and protect the user's hearing through noise reduction. Wherein, the noise reduction method includes an active noise reduction method and a passive noise reduction method. [0003] However, the existing earphone noise reduction method cannot adopt the preferred noise reduction method and set different noise reduction levels according to the sound frequency heard by the user, which is not conducive to effective noise reduction. The reason is that the existing earphone noise reduction methods all directly use active noise reduction methods ...
