Output manner of the aural signal, in the output manner of the speaker system,

摘要

PROBLEM TO BE SOLVED: To provide a speaker system for generating an output with big sound pressure without a deterioration in tone quality caused by clip.;SOLUTION: In a digital-signal processing device, a first band level for a sound signal is decreased, and signal processing for amplifying a level of a second band, which is different from the first band, is carried out according to the amount of attenuation. The sound signal, in which attenuation and amplification are performed, is generated from the speaker through a speaker amplifier.;COPYRIGHT: (C)2008,JPO&INPIT
