The invention discloses a noise elimination method and device, a storage medium and an earphone, and relates to the technical field of sound collection. Firstly, under the condition that a microphone collects a first audio signal, a vibration signal collected by a first sensor is obtained, then de-noising processing is carried out on the first audio signal based on the vibration signal to obtain a second audio signal, and the first audio signal comprises a noise signal generated by vibration. When the first audio signal comprises the noise signal generated by the vibration of the earphone, the vibration signal collected by the first sensor when the microphone collects the first audio signal can be obtained, and the noise signal and the vibration signal in the first audio signal have a corresponding relation. Therefore, the noise signal in the first audio signal can be eliminated based on the vibration signal to obtain the second audio signal, and the effect and accuracy of eliminating the noise signal generated by earphone vibration in the first audio signal are improved.
Description
technical field [0001] The present application relates to the technical field of sound collection, and in particular to a noise elimination method, device, storage medium and earphone. Background technique [0002] With the development of science and technology, people are increasingly using various earphones in their daily lives, and users can communicate and make voice calls through the microphone provided in the earphones. [0003] However, in the related art, when the earphone collects the external sound through the microphone, the external noise is usually also collected, so a noise elimination method is urgently needed to eliminate the noise in the sound data collected by the microphone. Contents of the invention [0004] The present application provides a noise elimination method, device, storage medium and earphone, which can solve the technical problem in the related art that when the earphone collects external sound through a microphone, the external noise is usu...
