Problems solved by technology

[0004] At present, the dual-mic noise reduction technology used in TWS earphones is mainly realized by algorithms such as beamforming, AEC acoustic echo cancellation, and AGC gain control. The external ambient sound can still be picked up and the total harmonic distortion of the low-frequency part of the caller's voice is relatively high, so the noise reduction effect still needs to be improved urgently

Abstract

The invention relates to the technical field of earphones, and discloses a call pickup and noise reduction method, an earphone and a storage medium. The method is applied to pickup equipment with a microphone and a voice acceleration sensor at the same time. The method comprises the following steps: acquiring a first sound signal through a voice acceleration sensor, and acquiring a second sound signal through a microphone; and synthesizing the first sound signal and the second sound signal to obtain a third sound signal. The earphone comprises a voice acceleration sensor which is used for collecting a first sound signal; a microphone which is used for collecting a second sound signal; and a signal synthesis module which is used for synthesizing the first sound signal and the second sound signal to obtain a third sound signal. According to the embodiment of the invention, the voice acceleration sensor and the microphone are combined and configured to synthesize the sound signals pickedup by the voice acceleration sensor and the microphone, and the synthesized signal is output to an opposite end, so that the signal-to-noise ratio and distortion of the sound of a wearer heard by a conversation object in conversation with the wearer are obviously optimized.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a method for picking up and reducing noise during a conversation, an earphone, and a storage medium. Background technique [0002] With the progress of society and the improvement of science and technology, more and more people begin to pay attention to the improvement of the quality of life, and more and more people start to use some audio-visual products, such as smart phones and wireless earphones, which are very convenient It not only improves the life of human beings, but also provides more fun for human beings. Especially for Bluetooth headsets, users can completely free their hands to communicate with others and enjoy music without restraint, so wireless headsets are loved by more and more users. [0003] In recent years, TWS (True Wireless Stereo, True Wireless Stereo) earphones have become the first choice of most users. TWS earphones are a device that transmits stere...
