Vehicle-mounted karaoke method, system and device and storage medium

The invention discloses a vehicle-mounted karaoke method, system and device and a storage medium, and the method comprises the steps: collecting an audio signal in a vehicle through a microphone in a karaoke mode; performing sound mixing processing on the audio signal and a music audio signal played in a karaoke mode to obtain a mixed audio signal; performing phase reversal processing on the mixed audio signal; performing power amplification processing on the inverted mixed audio signal, and outputting the signal to a vehicle-mounted loudspeaker for audio playing; the method does not depend on a hardware circuit, performs phase inversion on the audio signal through a software scheme, can effectively avoid self-excitation howling caused by re-pickup of a microphone in a vehicle-mounted karaoke process, and reduces damage to a sound system. 本发明公开了一种车载K歌方法、系统、设备及存储介质，该方法包括：在K歌模式下，通过麦克风采集车内的音频信号；将所述音频信号与在K歌模式下播放的音乐音频信号进行混音处理，得到混合音频信号；将所述混合音频信号进行反相处理；将反相后的混合音频信号进行功率放大处理，并输出至车载扬声器进行音频播放；本发明不依赖硬件电路，通过软件方案将音频信号进行反相，可
