Comment on Disconnect wire to close a switch with a simple circuit

Any possibility that you have some small solid state relays sitting around? Power to the coil can be the tripwire, so when that is cut and the relay closes the NC contacts it turns on the speaker

Nope! Mostly do computer repair / SMD rework, I’ve also tweaked some existing circuits to do what I want so this is probably my first foray into really tinkering and building something.

Alright. Well, I tried but I have really used transistors or MOSFETs since college. Those diagrams you had looked like they made sense to me, so the only thing I could think of is the transistors are expecting a different voltage from what the batteries are providing. But, it looks like some other people have responded that are much more familiar with transistors, good luck! I hope you get this working in time
