For simple circuits with one or two instruments, a "wall wart" would indeed make a useable supply.....Most will put out enough current at whatever voltage they are designed for.

Just make sure you read the fine print stamped on the one you select
and make sure the "output" is DC voltage, not AC.

Some "wallwarts are simple stepdown transformers and put out unrectified low voltage AC, which won't work the sounder very well.

So check out what you select carefully.
