ABSTRACT:
A reverberating platform structure usable as an exercise floor or, depending upon the configuration thereof, for the support of people or objects thereon wherein the platform is supported by an anchor structure above a foundation such that there is an open space between the foundation and the undersurface of the platform. The anchor structure may be essentially flexible so as to provide a giving or flexible structure to the platform for a person to exercise, dance, or otherwise move thereon. An agitator assembly primarily in the form of a plurality of speakers are disposed within the space immediately adjacent to the space slightly from the undersurface of the supporting platform wherein activation of the speakers causes vibration to be communicated directly to the platform but wherein the platform is further structured not to generate specific sounds therefrom so as to be considered part of the speaker system itself. The vibrations communication to the platform causes a reverberation thereof which is harmonious with any changes in the audible rhythmic changes of the vibrations emanating from the speakers.
