Phonofiddle

A phonofiddle is a class of stringed musical instruments that are played with a bow and use a phonograph type reproducer as a voice-box.

The sound producing diaphragm may be a metal cone as in the Stroh violin or a mica sheet as in the instruments made by A. T. Howson, London and the Stroviols company of Britain. The sound generated by the vibrations from the string or strings are transferred through the bridge to a connecting arm into the center of the diaphragm within the reproducer. The vibrating column of air is then directed into one or several horns.
