Bluetooth audio based karaoke method

Abstract

The invention provides a Bluetooth audio based karaoke method. A Bluetooth karaoke microphone and a mobile terminal in Bluetooth connection with the Bluetooth karaoke microphone are provided; the karaoke microphone and the mobile terminal are provided with a Bluetooth connection unit; and the karaoke method comprises the steps of carrying out Bluetooth pairing on the Bluetooth karaoke microphone and the mobile terminal by utilizing a Bluetooth connection unit; and after the successful pairing, building bidirectional connection of the Bluetooth karaoke microphone and the mobile terminal; picking up a human voice signal and carrying out sound processing on the human voice signal or not by the Bluetooth karaoke microphone; sending a music accompaniment signal to the Bluetooth karaoke microphone by the mobile terminal through a downlink; mixing the human voice signal which is subjected to the sound processing or not with the music accompaniment signal and playing back the mixed signals to a user to realize simulation of a real karaoke scene. Through carrying out reverberation processing on the human voice signal and mixing the human voice signal with the music in the microphone, and adopting a suitable Bluetooth audio transmission mean with high quality and extremely low time delay, the karaoke experience and high-quality voice sharing capacity of the user are improved efficiently.

Description

technical field [0001] The invention belongs to the field of electroacoustics, and in particular relates to a karaoke method based on bluetooth audio. Background technique [0002] With the gradual popularization of mobile terminals such as mobile phones and tablet computers and the continuous improvement of network bandwidth, various karaoke software suitable for mobile terminals are also used by more and more users, and are gradually becoming popular personal entertainment methods; Plug the wired microphone and earphone into the mobile terminal or directly use the microphone and speaker that comes with the mobile terminal. The former will be bound by the cable and the user experience will be poor, while the latter will easily produce echo and howling, which will cause the song effect to deteriorate. Neither of the other two can be realized. The real-time monitoring of the human voice makes the user lack a sense of presence; although the karaoke microphone adopting the wire...

Problems solved by technology

[0002] With the gradual popularization of mobile terminals such as mobile phones and tablet computers and the continuous improvement of network bandwidth, various karaoke software suitable for mobile terminals are also used by more and more users, and are gradually becoming popular personal entertainment methods; Plug the wired microphone and earphone into the mobile terminal or directly use the microphone and speaker that comes with the mobile terminal. The former will be bound by the cable and the user experience will be poor, while the latter will easily produce echo and howling, which will cause the song effect to deteriorate. The other two cannot be realized. The real-time monitoring of the human voice makes the user lack a sense of presence; although the karaoke microphone that adopts the wireless connection mode has also appeared in the prior art, its function is single, and the effect when the signal picked up is transmitted back to the mobile terminal by wireless mode is also poor. Poor, can not meet the user's higher pursuit of karaoke experience and sound quality
