ABSTRACT:
A sound activated fountain display. A plurality of transducers are disposed on the bottom of the pool of a fountain display with the fountain being normally off. Whenever a coin is tossed into the fountain's pool, the sound waves generated by the coin are received by the transducers, activating the fountain display. By gating the responses of the various transducers, the area of the pool in which the coin was tossed may be identified. In this manner, the display may be caused to be directed to that area of the pool, customizing the display for that particular viewer. If desired, the fountain display may be in a central pool with separate "satellite" coin pools surrounding the fountain and for activating the fountain display.
