ABSTRACT:
A portable audio apparatus allows a user to sing along with the recorded song, the user's voice and recorded song being outputted through a speaker. The apparatus permits the recorded lyrics or recorded tune of the song to be substantially eliminated prior to being reproduced by the speaker. The apparatus can operate in a fast forward or reverse mode and will stop between adjacent songs. A power savings circuit interrupts the supply of power to a motor to stop the latter from continuing to operate on a fast forward or reverse mode.
