Document Type and Number:
WIPO Patent Application WO/2023/020208
Kind Code:
A1
Abstract:
An audio signal processing method and apparatus, earphones, and a storage medium. The method is applied to earphones, and comprises: outputting a test audio signal by means of a loudspeaker, wherein the test audio signal is obtained by means of mixing a basic audio signal with an infrasonic wave signal; collecting, by means of a feedback microphone, a received audio signal corresponding to the test audio signal; and according to the received audio signal, determining a first equalization parameter corresponding to the basic audio signal, and a second equalization parameter corresponding to the infrasonic wave signal, wherein the first equalization parameter is used for performing, on a target audio signal to be output, ear-shape adaptive equalization for matching the ear shape of a user, and the second equalization parameter is used for performing, on the target audio signal, wear leakage adaptive equalization for matching the wearing state of earphones. By means of implementing the embodiments of the present application, earphones can provide personalized ear-shape adaptive equalization and wear leakage adaptive equalization for different users, thereby facilitating the improvement of the effectiveness of the earphones performing active noise cancellation on an audio signal.
