There are small utilities that *produce* such a click. Specifically designed for AmigaONE-users, who don't have floppydrives...

I attached a buzzer to to my minimig on pin 5 and 6 to get simulated floppy sound as the excellent firmware supports that.
It turned out to be too loud, so now I have covered the hole on the buzzer with electrical tape to reduce the noise
