<P>PROBLEM TO BE SOLVED: To suppress the influence on the frequency sound pressure characteristic of a speaker due to resonance generated by fixing an enclosure or the resonance of a device itself with respect to an electroacoustic reproducing device formed by incorporating the speaker into the enclosure. <P>SOLUTION: In this electroacoustic reproducing device, a vibration detecting device 5 is provided on the enclosure 2 or a bracket as a supporting member 3 to negatively feed a detected signal back to an amplifier 4 for driving the speaker 1, thereby correcting and reducing the vibration of the enclosure 2 or the supporting member 3 to prevent the generation of a resonant sound to improve sound quality. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
