<p><P>PROBLEM TO BE SOLVED: To provide a keyboard instrument capable of realistically reproducing key touching feeling when a string is hammered. <P>SOLUTION: A part 50 to be hammered by a hammer assembly rotated by pressing of a key has multilayer structure consisting of buffering members 52 and 54 for buffering the hammering force of the hammer assembly and an elastic member 53 for reproducing bending similar to the string. Bending of the string can be reproduced by gradually increasing the bending quantity of a part by each hammer assembly of the elastic part of the part 50 to be hammered according to shifting from a high pitch side to a low pitch side. Further, the sense of mass in a string can be reproduced by gradually increasing weight of the part to be hammered by each hammer assembly of the elastic member 53 of the part 50 to be hammered according to shifting from the high pitch side to the low pitch side. <P>COPYRIGHT: (C)2003,JPO</p> |
