[0022] Example one
[0023] figure 1 It is an implementation flowchart of a method for noise reduction of earphones provided by an embodiment of the present invention, which is detailed as follows:
[0024] In step S101, the earphone microphone is used to collect the noise signal of the environment;
Example Embodiment
[0025] Among them, there are two implementation methods for collecting the noise signal of the environment by using the headset microphone, which are detailed as follows:
[0026] The first implementation:
[0027] Every preset detection interval, the earphone microphone is used to collect the noise signal of the environment.
[0028] It should be noted that since the noise signal of the environment usually does not change much in a period of time, the noise signal of the environment is detected once every preset detection interval, which can further save the power consumption of the headset. .
[0029] The second implementation mode:
[0030] When the distance from the geographic location where the noise signal of the environment was collected last time is not less than the preset distance, the earphone microphone is used to collect the noise signal of the environment.
[0031] It should be noted that after the distance between the headset and the geographic location detected by the no...
Example Embodiment
[0043] Example two
[0044] figure 2 It is an implementation flowchart of the earphone noise reduction method S102 provided by an embodiment of the present invention, and the details are as follows:
[0045] In step S201, input part of the noise signal into the sampling channel;
[0046] In step S202, in the sampling channel, analog-to-digital conversion is performed on part of the noise signal to generate a noise value of the noise signal;
[0047] In step S203, the noise value corresponding to the noise signal is sent to the connected terminal.
[0048] In the embodiment of the present invention, the noise value corresponding to the noise signal is sent to the connected terminal, so that the receiving terminal can turn on the noise reduction function or turn off the noise reduction function according to the judgment result generated by the noise signal according to the judgment result.
