Bro there’s a Canadian guy on Youtube who built a loud-ass siren out of plywood in his garage. No speakers. No fancy electronics. Just a motor and some wood. These do not need to be complex things.
Exactly. A basic electric mechanical siren just consists of a motor, a centrifugal fan called a chopper, and a stator to chop the air as the rotor spins. It can’t get any simpler than that. There are tons of mechanical sirens from the 1920s and 30s that are still in service today because of how basic and easy to maintain they are!
