<P>PROBLEM TO BE SOLVED: To detect oscillations of strings of a thrumming stringed instrument efficiently and accurately. <P>SOLUTION: When a performance is carried out, the strings S, S, ... oscillate and the tension changes according to the oscillations, and the change is transmitted to a bridge SD and a pressure plate 30, and becomes a change in pressure to a supporting plate 31. As a result of this, the pressure plate 30 moves up and down together with the bridge SD, and a deflection amount of the supporting plate 31 changes. The change in the deflection amount of the supporting plate 31 is detected by a sensor 32 and outputted as a detection signal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
