VIOLIN HOOKED TO RADIO SET (Aug, 1933)
VIOLIN HOOKED TO RADIO SET
Stringed instruments without sounding boards, including violins, cellos, guitars, and ukuleles, have been devised by an eastern violin maker. Vibrations of the strings pass through the bridge to a magnetic pickup, resembling a microphone, that converts them into electric currents. These are amplified to operate a loudspeaker. At home the instruments may be plugged directly into the family radio. One of the new violins is illustrated above.
