ABSTRACT:
An electromagnetic pickup device for use in a tone generator of an electronic piano includes a plurality of vibratory reeds and pole pieces of pickups which are so shaped that each reed and pole piece are opposed to each other in a range from the neutral position of the reed to a position within its maximum vibrating amplitude at one side. In output signals of the pickups, the balance of fundamental and odd- and even-numbered harmonics is improved to generate a tone which is close to that of a normal string piano.
