Efficient noise reduction earphone with low power consumption and noise reduction system

Abstract

The present invention provides an efficient noise reduction earphone with low power consumption. The earphone comprises an earphone housing, the earphone housing is internally provided with a play horn, and the play horn is connected with a signal processing chip; the earphone further comprises a sensor arranged at the front end of the earphone housing to allow the sensor to stretch into a wearer's ear canal to collect jaw bone vibration signals at an inner ear; and the earphone further comprises a call microphone, the sensor collects the jaw bone vibration signals at an inner ear for voice activity detection and determines whether there is a person talking or not so as to guide an uplink conversation access to perform noise estimation for the signals collected by the call microphone and perform noise inhibition for the voice signals of the call microphone. The efficient noise reduction earphone with low power consumption employs the sensor to collect the jaw bone vibration signals atthe inner ear when the wearer is speaking, and does not need to perform echo elimination compared to a traditional earphone of an inner ear microphone which cannot collect music or conversation voicesignals played by a loudspeaker so that the power consumption is lower.

Description

technical field [0001] The invention relates to the technical field of sound signal processing, in particular to an efficient noise reduction earphone and a noise reduction system with low power consumption. 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 headset, mixed with what we say, and sent upstream to the earpiece of the other party's phone, affecting The voice quality of the other party answering the call, so the uplink noise reduction technology is very necessary. In addition, the wireless smart headset with built-in voice assistant can help users check the weather, answer calls, broadcast the weather, monitor heart rate, etc. The intelligent music recommendation system based on deep learning ...
