First Claim
1. A music sound correcting apparatus for correcting a music sound signal entered thereinto to selectively supply the corrected music sound signal to a speaker and a headphone, comprising:
- a jack into which a plug of said headphone is inserted;
a detector for detecting whether or not said plug of the headphone is inserted into said jack;
first correcting means for correcting said entered music sound signal to be properly reproduced by the speaker when said detector detects that said plug is not inserted into said jack; and
second correcting means for correcting said entered music sound signal to be properly reproduced by the headphone when said detector detects that said plug is inserted into said jack.

Abstract
A music sound correcting apparatus for correcting a music sound signal entered thereinto to selectively supply the corrected music sound signal to a speaker and a headphone, is provided with a jack into which a plug of the headphone is inserted, and a detector for detecting whether or not this plug of the headphone is inserted into the jack. When the detector detects that the plug is not inserted into the jack, a frequency of the entered music sound signal is changed so as to be properly reproduced by the speaker. On the other hand, when the detector detects that this plug is inserted into the jack, the entered music sound signal is corrected so as to be properly reproduced by the headphone in such a manner that a sound image produced based upon the entered music sound signal is localized to a predetermined position. As a result, preferable music sound can be reproduced even when the speaker is used and the headphone is employed irrespective of a small amount of hardware.

12. A music sound correcting apparatus for correcting a music sound signal entered thereinto to selectively supply the corrected music sound signal to a speaker and a headphone, comprising:
-
first storage means for storing an equalizing process program and a sound image localizing process program; second storage means, a content of which is rewritable; a jack into which a plug of said headphone is inserted; a detector for detecting whether or not said plug of the headphone is inserted into said jack; control means for transferring said equalizing process program read from said first storage means to said second storage means when said detector detects that said plug of the headphone is not inserted into said jack; and
for transferring said sound image localizing process program read from said first storage means to said second storage means when said detector detects that said plug of the headphone is inserted into said jack; anda digital signal processor for processing said entered music sound signal such that when said equalizing process program is transferred to said second storage means by said control means, said entered music sound signal is corrected in accordance with said equalizing process program to be properly reproduced by the speaker, and when said sound image localizing process program is transferred to said second storage means by said control means, said entered music sound signal is corrected in accordance with said sound image localizing process program to be properly reproduced by the headphone. - View Dependent Claims (13, 14, 15)
