Problems solved by technology

In order to meet the compact appearance requirements of users, the distance between the mics (full name in Chinese: microphone, full name in English: microphone) in the single-sided earphone is very close and the number is generally not more than 2, and the noise reduction quality is low.
In addition, the crosstalk of the digital signal line in the connection line to the spk or mic generates periodic noise, and the crosstalk of the signal in the spk line to the mic line forms an echo, which further leads to low noise reduction quality

Abstract

The invention discloses a wireless earphone noise reduction method and device, a wireless earphone and a computer readable storage medium. The wireless earphone noise reduction method comprises the steps: receiving a first electromagnetic signal transmitted from the earphone, and converting the first electromagnetic signal into an audio signal, wherein the first electromagnetic signal is obtainedby sensing an audio signal acquired from a microphone in the earphone through the coil; determining a to-be-denoised single earphone according to the audio signal acquired by the microphone in each single earphone; detecting whether an audio signal acquired by a microphone in the to-be-denoised single earphone has voice characteristics or not; and if so, carrying out noise reduction processing onthe audio signal collected by the microphone in the single earphone to be subjected to noise reduction by using a filter. According to the wireless earphone noise reduction method provided by the invention, the connecting line between the two ears is deleted, and the noise reduction processing quality and the user call experience are improved.

Description

technical field [0001] The present application relates to the technical field of wireless earphones, and more specifically, to a wireless earphone noise reduction method and device, a wireless earphone, and a computer-readable storage medium. Background technique [0002] In the related technology, the left and right ears of the wireless earphone are connected by a connection line, which usually includes a power line, an spk (full name in Chinese: loudspeaker, full name in English: statistical process control) line, and some digital control signal lines. In order to meet the compact appearance requirements of users, the mics (full name in Chinese: microphone, full name in English: microphone) in the single-sided earphone are very close to each other and the number is generally not more than two, and the noise reduction quality is low. In addition, the crosstalk of the digital signal line in the connection line to the spk or mic generates periodic noise, and the crosstalk of ...
