Wireless karaoke microphone headset

Abstract

The invention discloses a wireless karaoke microphone headset which comprises a left microphone, a right microphone, an ADC (analog-to-digital converter), a reverberation effect unit, a sound mixing unit, a DAC (Digital To Analog Converter), a left loudspeaker, a right loudspeaker and a wireless connection unit which are positioned at auricular positions when a user wears the headset. Voice signals picked up by the left and right microphones enter the reverberation effect unit after being subjected to analog-to-digital conversion by the ADC; after carrying out reverberation effect processing on the digital voice signals, the reverberation effect unit sends the digital voice signals to the sound mixing unit; the wireless connection unit receives a music accompaniment signal sent by a mobile terminal and sends the music accompaniment signal to the sound mixing unit; the sound mixing unit mixes the voice signals with the music accompaniment signal and sends a mixed signal to the DAC; after digital-to-analog conversion, sound is output to the user by the left and right loudspeakers; and the headset can send the sound mixed signal, the voice signals or a holographic sound field signal to the mobile terminal in a Bluetooth manner. By the wireless karaoke microphone headset disclosed by the invention, karaoke experience of the user and sharing capacity of high-quality sound an be effectively promoted.

Description

technical field [0001] The invention belongs to the field of electroacoustics, in particular to a wireless karaoke microphone earphone. 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 there have been karaoke microphones that adopt wireless...

[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 there have been karaoke microphones that adopt wireless connection in the prior art, their functions are single, and the effect when the picked-up signal is transmitted back to the mobile terminal by wireless is relatively low. Poor, unable to meet users' needs for karaoke experience and sound quality
