Abstract:
Disclosed are a method for realising a karaoke function through an earphone, and an earphone. The method comprises: receiving a voice signal collected by a microphone of an earphone; performing analogue-to-digital conversion processing on the voice signal to obtain a digital voice signal; filtering out a human voice signal in a digital music signal received by the earphone to obtain a background music signal; superposing the background music signal and the digital voice signal to obtain a digital superposed signal; and performing digital-to-analogue conversion processing on the digital superposed signal to obtain a simulated superposed signal, and sending the simulated superposed signal to a receiver of the earphone. In the present invention, a singing voice signal, collected by a microphone, of a singer and a background music signal obtained by eliminating a human voice signal in a music signal are superposed by an earphone, so that a karaoke effect is realised in real time through the earphone, and the user experience is improved.
