Abstract
660,741. Musical instruments. COOPER, F. T. Aug. 11, 1949. No. 20883/49. Class 88 (ii). A pick-up device for detecting the vibrations of ferro-magnetic reeds, strings or sound pieces of musical instruments comprises two parallel iron bars A with several small magnets clamped between them and surrounded by a coil D. The string or reed is arranged perpendicular to and close to the long edges of the bars so that its vibration changes the magnetic flux in the coil to produce an e.m.f. therein for amplification and feeding to a loudspeaker. A pick-up so constructed is sufficiently compact to mount within a normal piano.
