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.
