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...
