PURPOSE:To cancel an influence due to the difference of the positions of the diaphragms of respective speakers without the deterioration of the quality of a signal by inputting a sound signal to a processor, generating the signal for every reproducing band, applying a prescribed delay for every signal and then inputting to a power amplifier. CONSTITUTION:A signal from a digital source 1 is inputted to a digital signal processor 6 and the signal is generated for every reproducing band. After a prescribed delay (t) is added for respective signal to convert in D/A converters 7, 8, input to respectively corresponding power amplifiers 9, 10 and drive the respectively corresponding speakers 11, 12. The delay (t) is added only to the signal in which the diaphragm is near to an audible position and the difference (d) of the position of the diaphragm is apparently cancelled. |
