Hello guys, i need to make something very very very cheap, which needs to be built in ~10K peaces.
Thing is very basic, i have very simple and short audio which i need to reproduce once one button is pressed. It doesn’t need to be good sound, and it needs to be in a size of keychain.
Only one long word and that is all.
Please help me with a parts. I think piezo speaker could do that, (flat one like coin) but i don’t know if it is possible to make it without any microcontroller to “say” something". and as i said, i need something very cheap and easy to assemble, so if possible, without microcontroller??
If not, than what would be the most affordable and most easy to build option?
