An earphone noise reduction method comprising: utilizing an earphone microphone to collect noise signal of an environment where the earphone microphone is positioned when either: a distance between a geographic position where the earphone is currently positioned and a geographic position where the noise signal of the environment where the earphone microphone was positioned was collected last time is not less than a predetermined distance; or a distance between the geographic position where the earphone is currently positioned and the geographic position where the noise signal of the environment where the earphone microphone was positioned was collected last time does not exceed the predetermined distance and a time duration since the noise signal of the environment was detected last time by the earphone exceeds a predetermined time interval, wherein utilizing the earphone microphone to collect the noise signal of the environment at every predetermined time interval; transmitting the noise signal to a terminal connected to the apparatus, or transmitting a noise value corresponding to the noise signal to the connected terminal; receiving a judgement result returned by the terminal, and enabling a noise reduction function or disabling the noise reduction function according to the judgement result; and wherein the transmitting a noise value corresponding to the noise signal to the connected terminal is specifically: inputting a portion of the noise signal into a sampling channel; performing analog-to-digital conversion to the portion of the noise signal in the sampling channel to generate a noise value of the noise signal; transmitting the noise value corresponding to the noise signal to the connected terminal. utilizing an earphone microphone to collect noise signal of an environment where the earphone microphone is positioned when either: a distance between a geographic position where the earphone is currently positioned and a geographic position where the noise signal of the environment where the earphone microphone was positioned was collected last time is not less than a predetermined distance; or a distance between the geographic position where the earphone is currently positioned and the geographic position where the noise signal of the environment where the earphone microphone was positioned was collected last time does not exceed the predetermined distance and a time duration since the noise signal of the environment was detected last time by the earphone exceeds a predetermined time interval, wherein utilizing the earphone microphone to collect the noise signal of the environment at every predetermined time interval; transmitting the noise signal to a terminal connected to the apparatus, or transmitting a noise value corresponding to the noise signal to the connected terminal; receiving a judgement result returned by the terminal, and enabling a noise reduction function or disabling the noise reduction function according to the judgement result; and wherein the transmitting a noise value corresponding to the noise signal to the connected terminal is specifically: inputting a portion of the noise signal into a sampling channel; performing analog-to-digital conversion to the portion of the noise signal in the sampling channel to generate a noise value of the noise signal; transmitting the noise value corresponding to the noise signal to the connected terminal. inputting a portion of the noise signal into a sampling channel; performing analog-to-digital conversion to the portion of the noise signal in the sampling channel to generate a noise value of the noise signal; transmitting the noise value corresponding to the noise signal to the connected terminal. <EOS>
