Hi all-
This is my first post, so apologies if this is too simple or in the wrong place. Years ago I took an electronics class, but I've forgotten most of what I learned due to lack of use. Still, what I want seems like it would be simple, and I can still solder and identify components, so I figured I'd ask here.
I've built a game show set like Jeopardy which is entirely relay-driven. The last piece I need is a "ding" sound when a users buzzes in. I previously solved this by using the back door solenoid of a doorbell, but that solution was quite large and problematic, because when a relay fired, it would close the doorbell circuit and keep the solenoid engaged, weakening it and eventually burning it up. I fixed it with a manual kill switch on the doorbell, but the overall solution is too big and complex to be sustainable. I'm looking for something a bit more elegant.
My thought is to make a simple (and small) solution that uses 12vdc to fire off a single chime sound even though the switch that fires off the chime may stay closed for a while. (Bonus points if the sound resonates and fades like a bell would
Also, ideally, this would output line-level audio that we could plug into a house audio system (we use this game show set at events that my company produces).
Thanks so much in advance! I wish I knew where to begin with a circuit design nowadays, but I'm 15 years removed from the last time I really designed something that did more than flash a light bulb
Thanks again,
Gabe
