A karaoke device is included within an enclosure and having a voice pickup element integrated into the enclosure for converting sound waves into an electrical signal. An audio input signal from a DVD player passes into the enclosure and into an electronic circuit for amplifying the electrical signal, for controlling the amplitude of the electrical signal and for mixing the electrical signal and the audio input signal into a mixed audio signal. The resulting audio output signal is delivered to an output device such as a television.
