Neck ring Bluetooth earphone, and noise reduction system and noise reduction method of neck ring Bluetooth earphone

Abstract

The invention provides a neck ring Bluetooth earphone. The earphone comprises an annular supporting structure with an opening and an earphone telephone receiver connected to an earphone line extendingout from the annular supporting structure; an outward auxiliary microphone is arranged at the middle of the annular supporting structure, and an inward first main microphone is installed at one end of the annular supporting structure or a second main microphone is installed on the earphone line. The neck ring Bluetooth earphone provided by the invention can effectively eliminate the ambient noiseand the talk voice of others so as to achieve a better noise reduction effect and ensure a cleaner call environment.

Description

technical field [0001] The invention relates to the technical field of bluetooth noise reduction earphones, in particular to a neck ring bluetooth earphone, a noise reduction system and a noise reduction method for the neck ring bluetooth earphone. Background technique [0002] With the progress of society and the improvement of people's living standards, earphones have become an indispensable daily necessities in people's lives. People often answer and make calls on the street, bus, and subway. The noise in this environment will be picked up by the microphone of the earphone, mixed with the content of the near-end speech, and sent upstream to the earpiece of the far-end phone. , affect the voice quality of the far-end answering the phone, so the uplink noise reduction technology is very useful. Speech enhancement during a call has always been a subject of great concern. In a noisy environment, how to enable the far-end caller to clearly hear the information that the near-e...

AI Technical Summary

Problems solved by technology

The current ordinary Bluetooth headset basically does not have the uplink noise reduction function, and the uplink call generally uses a single microphone noise reduction function, the noise reduction ability is limited, and the effect is only good for stable noise, and the effect of suppressing other noises in the environment is poor.

When making a call in shopping malls, subways and other environments, in addition to the ambient noise, the voice heard by the far-end caller is mixed with the voices of other speakers other than the headset user, and the noise reduction effect is poor.

In the prior art, because filtering the useful signal in the auxiliary microphone will improve the sound quality, but the overall filtering will also change the background noise in the auxiliary microphone, so that the background noise signal in the auxiliary microphone is different from the background noise signal in the main microphone If it is too large, it will affect the noise reduction effect
