Problems solved by technology

However, whenever the filter coefficients are actively adaptively adjusted, repeated calculations are required to determine the filter coefficients of the filter components based on the audio signal and the transfer function, which undoubtedly increases the computational load of the system
In the process of dynamically updating the noise reduction parameters of the headset, it will consume a lot of computing resources and will also affect the adjustment speed
[0005] Obviously, the existing earphones cannot solve the above problems

Abstract

The invention relates to a method for earphone noise reduction and a noise reduction earphone. The earphone comprises a sensor and a filter assembly, and the method comprises the steps: detecting thecurrent capacitance of a human ear through the sensor; determining a current noise reduction parameter on the basis of the current capacitance, referring to N groups of corresponding relationships between preset capacitance of the human ear wearing the earphone and preset noise reduction parameters, N being a positive integer, and the noise reduction parameter comprising a filter coefficient of afilter enabled in the filter assembly; and configuring the filter assembly according to the current noise reduction parameter to reduce noise. According to the invention, the capacitance value at thecorresponding position of the human ear is detected through the sensor configured on the earphone, and the noise reduction parameter of the filter assembly in the earphone is further determined basedon the capacitance value; therefore, dynamic adjustment of the noise reduction parameters of the earphone can be conveniently and quickly realized, the noise reduction effect in different use scenes is ensured, the calculation load of the system is reduced, and the listening experience of a user is improved.

Description

technical field [0001] The present disclosure relates to the field of earphones, and more particularly, to a method for noise reduction of earphones and the noise reduction 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 noise suppression function can enable users to enjoy a comfortable noise reduction experience in various noisy environments such as airports, subways, airplanes, restaurants, etc., and are increasingly widely recognized by the market and customers. However, different noise conditions, different earphone wearing styles, and different ear canal structures will all affect the noise suppression function of the existing earphones, and also bring users an unsatisfactory use experience. [0003] First of all, the noise reduction effect of headphones is greatly affected by different wearing methods and differen...
