Strange found object: Disney Sound Converter

From XYHD.tv

Picture 14-4 Found amongst a co-worker's collection of connectors we came across this Disney Sound Converter, complete with Mouse Ears. Done in shiny chrome, with what looks like a Parallel port, and phone jack. Is this the control device for Walt's Cryo-tube?

Chime in if you know what this really is.
