Abstract
Abstract A solid-state sound effect generating system for selectively producing any one of a plurality of predetermined sound effects has a plurality of interchangeable plug-in printed circuit boards each having mounted thereon an electronic circuit capable of being actuated to produce an electrical output signal representative of a unique one of a group of desired sound effects, without the use of any prerecorded signals or recording medium. The circuit boards are plugged into a common control chassis which interconnects them with an audio power amplifier and loudspeaker arrangement and which further provides input terminals for external triggering signals.

Claim 1
Independent Claim
176 words
An interchangeable plug-in printed circuit board for use with an electronic sound-generating system for an audio-visual amusement device of the type in which specific events are each accompanied by a corresponding predetermined sound effect, and in which said system includes a control chassis having a plurality of jacks for interchangeably changing and receiving a plurality of said circuit boards, said chassis further having means for interconnecting said received circuit boards, said circuit board comprising a non-conductive substrate having mounted thereon an electronic circuit capable of being actuated to develop an electrical output signal representative of a unique one of said sound effects, said substrate having a plug portion including a plurality of contacts adapted to mate with said jacks; and means mounted on the substrate for providing manual adjustment of the volume of said unique one of said sound effects, whereby a unique one of said sounds provided by signals from one circuit board may have a volume that is adjustably different from another unique one of said sounds provided by signals from another circuit board.
