Abstract

979, 240. Electrophonic musical instruments. MATTH.HORNER A.G. Dec. 3, 1962 [Dec. 1,1961], No.45604/62. Heading G5J. In an electrophonic musical instrument, a mechanical oscillator element such as a reed 16 is deflected from its normal rest position by a finger 11 on a key when the key is unoperated. Depression of the key releases the reed and allows it to vibrate. A rubber member 12 on finger 11 carries a damper-pad comprising a layer 14 of soft rubber or foam and a thin outer layer 15 of leather. The outer layer 15 may be coated with a tacky adhesive so that the reed is plucked as the key is depressed. The keys are mounted on pivots 3. The white keys 1 are spring-biased against a stop 10 with a soft contact surface 9. The black keys 2 are biased against a soft contact surface 6 on a buffer strip 7. The vibrating reed generates an electrical signal in either an electrostatic or an electromagnetic pick-up. The voltage generated by a reed depends upon its amplitude of vibration and therefore upon the touch or impulse imparted to the key. Electrostatic pick-up. An electrode 22 common to a group of notes is mounted in a slot 21 in a non-conducting base 20 and is itself slotted at 22a Fig. 2 to form a section opposite each reed 16. An adjustment can be made for each individual note by bending the section with a screw. The electrode section adjacent the tips of the reeds may be terminated as shown in Figs. 4, 5 or 6. A circuit is described (Fig. 7 not shown). Electromagnetic pick-up. Reeds 65 to 68, Fig. 9, which may be of stainless steel, are arranged with their tips adjacent magnetic pole shoes 55 to 62, Fig. 8, mounted in a groove 63 in a non-magnetic base plate 64. The pole shoes are wound as shown with more turns linked with the pole shoes associated with reeds of higher frequency. The windings are connected through a transformer 70 and amplifiers 71, 73 to a loudspeaker. Specification 809,853 is referred to.
