Abstract

A sound reproducing apparatus is structured to use a first dividing circuit and a determining circuit to analyze a frequency characteristic of an inputted signal and to output a signal adjusted by a first adjusting circuit to have a prescribed frequency characteristic by a switching by a switch circuit. Thus, when signals having different frequency characteristics are inputted, frequency characteristics of the input signals can be automatically adjusted without using an external signal and channels having different frequency characteristics can be reproduced by a single system to provide good speaker-reproduced sound.

Claims (14)

1 . A sound reproducing apparatus comprising:

a music signal source;

a dividing circuit formed of at least one filter for dividing the music signal source into prescribed bands;

a determining circuit for determining a frequency included in the music signal source based on an output from the dividing circuit;

an adjusting circuit formed of at least one filter for adjusting a frequency characteristic of the music signal source to a prescribed frequency characteristic; and

wherein a signal adjusted to a prescribed frequency characteristic is outputted by controlling the switch circuit using an output from the determining circuit.

2 . The sound reproducing apparatus according to claim 1 , wherein

the sound reproducing apparatus includes the plurality of dividing circuits, and

the determining circuit receives signals having prescribed bands of the music signal source outputted from the plurality of dividing circuits.

3 . The sound reproducing apparatus according to claim 1 , wherein

the sound reproducing apparatus includes the plurality of adjusting circuits.

4 . The sound reproducing apparatus according to claim 1 , wherein

the sound reproducing apparatus includes the plurality of adjusting circuits and the plurality of dividing circuits, and

the determining circuit receives signals having prescribed bands of the music signal source outputted from the plurality of dividing circuits.
