Zusammenfassung:	Provided is an acoustic apparatus capable of causing a sensation that a sound is produced in a larger space than reality, without requiring an excessive cost and time-consuming installation. The sound collected by a microphone is converted to an electrical signal, and a reflected sound component is extracted by a signal processing portion. The reflected sound component thus extracted is amplified by an amplifier, and the reflected sound component thus amplified vibrates transducers attached to a back-side board surface of each acoustic structure, whereby reflected sound is emitted from all faces including front-side board surface and the back-side board surface. A player can thus naturally perceive as if the space where he stays is expanded.
