Abstract

The invention relates to a noise reduction method and system for a semi-in-ear earphone, and the semi-in-ear earphone, and the method comprises the steps: responding to a condition that a loudspeakerof the semi-in-ear earphone does not play an audio signal, and calculating a first coefficient of a first filter bank; calculating a second coefficient of a second filter bank in response to a condition that the loudspeaker plays the audio signal; determining a third reference coefficient of the first filter bank based on the first reference coefficient and the second reference coefficient, so asto eanble the first filter bank to perform filtering by using the third reference coefficient, the first reference coefficient being a preset coefficient of the first filter bank, and the second reference coefficient being a preset coefficient of the second filter bank; and determining a calibration coefficient of the second filter bank based on the first coefficient, the second coefficient, the first reference coefficient and the second reference coefficient, so as to enable the second filter bank to perform filtering by using the calibration coefficient. According to the invention, the noisereduction effect of the half in-ear earphone is improved, and the measurement error caused by path measurement is counteracted.

Description

technical field [0001] The present disclosure relates to the field of earphones, and more specifically, to a noise reduction method and system for semi-in-ear earphones and semi-in-ear earphones. Background technique [0002] With the progress of society and the improvement of people's living standards, earphones have become an indispensable daily necessities for people. Headphones with active noise suppression can enable users to enjoy a comfortable noise reduction experience in various noisy environments such as airports, subways, airplanes, and restaurants. Compared with in-ear headphones, semi-in-ear headphones are more and more widely recognized by the market and customers because of their wearing comfort. However, different noise conditions, different earphone wearing styles, and different ear canal structures will affect the noise suppression function of the existing semi-in-ear earphones, and also bring users an unsatisfactory experience. [0003] First of all, mos...
