PURPOSE:To enable rich performance expression by eliminating the simplicity of sound quality. CONSTITUTION:Six main piezoelectric elements 19 are fixed to a bridge 16 arranged on a base 13 and respective strings 6 are pressed against the upper end parts of the main piezoelectric elements 19. Further, an up-down adjusting screw 21 formed by inserting a spring 20 is engaged threadably with the base 13 and a holder 22 is held elastically between the head part of the up-down adjusting spring 21 and the upper end part of the spring 20. The holder 22 is fitted with six subordinate piezoelectric elements 24 corresponding to the respective strings 6 and the subordinate elements are arranged at places where they contact the strings 6 when the strings vibrate. |
