Title: Violin Or Other Stringed Instrument
What’s claimed: “A stringed musical instrument, comprising in its construction a bridge supporting the strings, a rocking lever connected with the said bridge and supporting the same, a diaphragm held and supported at the edges and adapted to oscillate in the center, a transmitting device situated between the extremity of the rocking lever and the diaphragm and adapted to transmit oscillations from the said lever to the diaphragm, a resonator situated in proximity to the diaphragm and adapted to receive and distribute the waves of air caused by the vibrations of the diaphragm, and a body portion adapted to support the rocking lever diaphragm and resonator and to connect these parts with the parts holding the ends of the strings, substantially as described.”
Why this patent rocks: This patent appears to be the Stroh Violin, invented by electrical engineer John M A Stroh in 1899. The Stroh Violin is a type of stringed musical instrument that is mechanically amplified by a metal resonator and horn attached to its body. For more information, see here.
