Wireless karaoke microphone

Abstract

The invention provides a wireless karaoke microphone which comprises a microphone body, an analog-digital conversion (ADC) unit, a reverb effect unit, a sound mixing unit, a digital-analog conversion (DAC) unit, a monitoring playback unit and a wireless connection unit, and is characterized in that a voice signal collected by the microphone body enters the reverb effect unit after being subjected to analog-digital conversion of the ADC, the digitalized voice signal is sent to the sound mixing unit after being subjected to reverb effect processing by the reverb effect unit, the wireless connection unit receives a music accompaniment signal sent by a mobile terminal and sends the signal to the sound mixing unit, the sound mixing unit mixes the voice signal with the music accompaniment signal and sends a sound mixed signal to the DAC, sound is output to a user by the monitoring playback unit after the sound mixed signal is subjected to digital-analog conversion, and the microphone can send the sound mixed signal or the voice signal to the mobile terminal in a Bluetooth manner. According to the wireless karaoke microphone, the karaoke experience of the user and sharing capacity of high-quality sound can be effectively improved.

Description

technical field [0001] The invention belongs to the field of electroacoustics, in particular to a wireless karaoke microphone. 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 wireless connection mode has...

[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
