Abstract
A type of portable karaoke device includes a microphone, a twist knob control, several control buttons and a composite A/V output. There is an audio processor and a MPEG decoder inside the microphone. That audio processor is used to receive audio signals from the microphone and voice signals created by the MPEG decoder, and then conduct audio processing for these signals. On the other hand, that MPEG decoder is used to receive karaoke signals and control signals, and then conduct decoding and audio and video processing for these signals. The twist knob control is on the surface of the microphone, and can be used to adjust the volume or move the cursor by turning left or right. Several control buttons are on the surface of the microphone. Control signals can be generated by pressing. Audio and video output ports are set outside the microphone, it can transmit the video and audio signals from the karaoke device to another visual display device (e.g. TV).
