Everyone just calls them sound modules, or "Greeting card sound modules" if
they're feeling talkative.  The trade name is "COB sound module", COB=chip
on board.  You can get just the PCB for the more popular sounds, you supply
3v & speaker.

Kitsrus used to have them, train whistles & such.

You might be able to get a bunch as samples.

They turn up as surplus occasionally, if you're not fussy about the tune:

Possibly even worse, at least they're cheap:
