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.
