Old style radio horn or, if you stretch your imagination, something 
resembling an Edison cygnet horn without the scalloped flare.

I just picked up an Ampli-Phone, which is made by Robert "Look For The 
Dog" Baumbach's company and was designed by him based on the exponential 
horn dimensions in the Orthophonic Victrola. It's not earth-shattering - 
there's only so much you can do with output from a speaker smaller than 
a thimble - but I think it works well within its given limitations.
