Portable audio apparatus having a power savings device

DETAILED DESCRIPTION Generally speaking, in accordance with the invention, a portable audio apparatus permits a user to sing along as a recorded song is played with the user's voice and song outputted in unison through a speaker.
A sound reproducing device produces a recorded vocal signal based on the recorded lyrics and a recorded musical tune signal based on the recorded tune.
A synthesizing device combines the recorded vocal signal with the recorded musical tune signal and produces an output signal in response thereto representing the combination of the two signals.
An adjusting device is operable for varying the combination of the recorded vocal signal and the recorded musical tune signal represented by the output signal.
A control device can set the adjusting device to a predetermined combination of the recorded vocal signal with the recorded musical tune signals.
This predetermined combination can be outputted through the speaker so that a user who has forgotten the lyrics to the song can be assisted by listening to the recorded lyrics.
A microphone produces a vocal signal representing the user's voice.
The synthesizing device adds this vocal signal to the output signal.
The adjusting device includes an attenuating element for changing the magnitude of the recorded vocal signal and musical tune signal prior to combining the two signals to form the outputted signal.
In accordance with another aspect of the invention, a power saving device is included in the portable audio apparatus.
A motor is provided for moving the recording medium in at least forward, fast forward and rearward modes.
A sound reproducing device is provided for reproducing the recorded vocal sound signals and the recorded musical tune signals stored on the recording medium.
A detecting device determines when the combined recorded vocal signal and musical tune signal are below a predetermined level and produces an output signal based thereon.
An additional control device controls the supply of power to the motor in response to the output signal of the detecting device
