ABSTRACT:
A novelty device for sustainingly bouncing an object such as a ball. The cone of a loud-speaker is covered by a taut elastic diaphragm against which the object is bounced. When the object strikes the diaphragm, the speaker produces a small electrical pulse which is amplified and returned to the speaker. The amplified pulse is thereby acoustically coupled to the diaphragm which is snapped to restore sufficient energy to the object to overcome frictional losses.
