Abstract

The invention relates to a music playing apparatus for portable device that can amplify acoustic signals from a portable device (12) before allowing speakers (13, 14) to output the acoustic signals and comprises a model differentiation mechanism (21) for differentiating the model type of the portable device (12) according to a status signal from a connector (19) of a cable (17) for connecting the portable device, and a volume/tune adjustment mechanism (22) for outputting a volume/tune adjustment signal according to the model type of the portable device (12) differentiated by the model differentiation mechanism (21), and a volume/tune adjustment amplifier (20) for adjusting the volume and tune of the acoustic signal inputted from the portable device (12) according to the volume/tune adjustment signal from the volume/tune adjustment mechanism (22). Thus, the acoustic signal amplifying apparatus (11) can be connected to an output part of a stereo composite acoustic system (13) to play large-volume and high-quality sound.
