<p><P>PROBLEM TO BE SOLVED: To provide a keyboard instrument for generating sound by vibrating a cantilever vibration plate, in which generated sound volume is made large, and in which expression is improved by making the generated sound rich. <P>SOLUTION: The keyboard instrument includes a plurality of vibration plates 24, 25 and 26 attached to a resonance object i27 n a cantilever form. A key 11 is supported by a key support part 12 fixed to a frame FR to be rocked. A plurality of picking members 21, 22 and 23 for picking each of the vibration plates 24, 25 and 26 are attached to a rear part of the key 11. At least one characteristic vibration frequency in the vibration plates 24, 25 and 26 is set to a frequency corresponding to a key pitch of the key 11, and the identical vibration frequency of the other vibration plates is made slightly different from the frequency corresponding to the key pitch of the key 11. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
