Say that you suddenly wake up in the year 1875. You end up talking to someone and you want to convince them that you’re from the future. How do you do that?

strikes me as easier to make a working prototype of a phone. at least if simple speakers and mics already exist. did they?
The microphone was part of Alexander Graham Bells invention I believe. I assume speaker was included as well, otherwise what would it be used for, the radio wasn’t around yet
I was thinking maybe gramophone or earlier precursors. But looking at those things they’re mechanically coupled not electrically, so not really the same thing.
