It looks like some sort of amplification device based on the Automatic speaker to me, but I've never seen one before. It appears to have two diaphragms, so it must have a sold linkage between the two to activate them simultaneously for both outlets.
I'm sure it's mighty rare whatever it is.

Looks like a type of polyphone attachment, but not the one usually seen made by Edison.

Wow - - that's an Edison "Duplex" Speaker, offered briefly in 1896. It originally sold for $9.00 and they're rare as hen's teeth. Why can't I stumble across one of these??? ;D

Edison didn't make the Polyphone attachment. It was a product of the Polyphone Company which was founded by Leon Douglass.
