Abstract

The invention discloses a wireless earphone noise reduction calibration method and device, an earphone box and a computer readable storage medium. The method comprises the following steps: carrying out on-box detection on the wireless earphone, and when the wireless earphone is in an on-box state, obtaining a first sensitivity from a loudspeaker in a left earphone to a first noise reduction microphone and a second sensitivity from a loudspeaker in a right earphone to a second noise reduction microphone; calculating a first gain of a first noise reduction circuit in the left earphone and a second gain of a second noise reduction circuit in the right earphone by using a difference value between the first sensitivity and the second sensitivity; writing the first gain into the first noise reduction circuit, and writing the second gain into the second noise reduction circuit so as to complete noise reduction calibration. According to the wireless earphone noise reduction calibration methodprovided by the invention, the gain values of the left and right earphone noise reduction circuits are recalculated by using the sensitivity difference between the left and right earphone loudspeakersand the noise reduction microphone, and the calibration of the noise reduction amount of the left and right earphones is realized by adjusting the difference of the gain value balance sensitivity.

Description

technical field [0001] The present application relates to the technical field of wireless earphones, and more specifically, to a wireless earphone noise reduction calibration method and device, an earphone box, and a computer-readable storage medium. Background technique [0002] With the popularization of wireless headset technology, its share in the overall headset market in the e-commerce market has greatly increased. At the same time, the noise reduction function has become the standard configuration and selling point of more and more wireless headphones. For wireless earphones with noise reduction function, there should be no significant difference in the amount of noise reduction between the two ears, otherwise it will affect the user's experience. However, due to the different sensitivities in different single earphones, on the premise that the shape consistency of the noise reduction circuit is stable, there are differences in the noise reduction of different single...
