Originally, the ultimate goal required in loudspeaker systems is to realize flat frequency character istics. However, from the pleasant sound standpoint, loudspeaker systems with flat frequency characteristics do not all w ays produce testy sound. We i ncorporate the movable sound mechanism in the resonance port of the loudspeaker systems. By automa tically synchronizing the movement with music, the Helmholtz resonance frequency is controlled to the frequency of sound to be enhanced. As a result, l oudspeaker systems in which the resonance frequency changes in the real-time manner are developed. These loudspeaker systems also have the visual entertainment nature that a resonance port moves to real-time manner according to music. We played music using these loudspeaker systems, and evaluated them in sense using the AHP method. From the result of the evaluation, the pred ominance of new loudspeaker systems which we developed is proved here.
