Every karaoke set has common basic parts. The first one is the music player itself which can play the music from a cassette, vinyl, CD, or even from a smartphone or laptop. The second major element is the microphone that people can sing into. A typical karaoke system will support either a single or dual microphone jack. Unlike regular microphones, a kid’s karaoke set will have options to adjust the pitch. Finally, there is the speaker. In some karaoke sets, there will be some additional features as well. A screen that can display the lyrics for the song is a well-loved feature to have.
