Abstract

The embodiment of the invention provides a method and a system for unvarnished transmission of an earphone, and the earphone. The earphone comprises a feedforward microphone, an unvarnished transmission filter, a loudspeaker and a leakage removing filter. The method comprises the following steps of: collecting an audio playing signal transmitted to the loudspeaker for playing and transmitting to the leakage removing filter, and the audio playing signal comprises an audio signal generated by superposing an environment sound signal collected by the feedforward microphone and passing through thetransparent transmission filter and a to-be-played audio signal; and superposing the audio playing signal processed by the leakage removing filter and an environment sound signal acquired by the feedforward microphone, and transmitting the superposed signals to the transparent transmission filter so as to eliminate the leaked audio playing signal played by the loudspeaker and played by the feedforward microphone.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to a method, system and earphone transparent transmission for earphones. Background technique [0002] At present, headphones with active noise suppression function can enable users to enjoy a comfortable noise reduction experience in various noisy environments such as airports, subways, airplanes, restaurants, etc., and are increasingly widely recognized by the market and customers. However, in some scenarios that need to receive signals such as external voice or external environmental noise, the headset needs to have a transparent transmission function while performing active noise reduction, so that the wearer of the headset can better receive external voice, external environmental noise or External alarm, etc. [0003] However, when the active noise reduction headset is in the transparent mode, the audio from the speaker will leak out of the ear and be collected by the feedforwa...
