<P>PROBLEM TO BE SOLVED: To provide a musical percussion instrument capable of generating excellent sound, even if any position of a hit face is hit. <P>SOLUTION: A plurality of sound bars is arranged at a backplane of a plate surface 10 in the musical percussion instrument 1 having the same shape with a guitar body. A side face of the sound bar has a trapezoid shape, and a face of a lower edge side of the trapezoid shape is stuck to the plate surface 10. When the plurality of sound bars is arranged at the backplane, the backplane is divided into a plurality of regions, but they are arranged so that areas of the plurality of regions may not be different from each others. When the table 10 is hit, the table 10 vibrates. Since this vibration transmits to a whole table 10 via each sound bar, there leave few places where phase difference arises by the vibration of the table 10, and excellent sound is generated. <P>COPYRIGHT: (C)2008,JPO&INPIT |
