My Miata's speedometer used to do this. My good friend Eric described the sound as akin to a choo-choo train. My memory is fuzzy, so I'm going to pretend he used those exact words. He's a grown-ass man. I tried replacing the speedometer head before, but that didn't help.
As part of the engine rebuild, I replaced many (many!!) parts. One of them was the speedometer cable, which is easier to replace than I expected. Problem solved! I lived with that annoyance for way too long considering how simple the fix was. With a little dexterity, flexibility and profanity, I was able to replace the cable without removing the instrument cluster.
