  • Patent number: 7087828
    Abstract: An innovative music instrument (101) comprises at least one tunable string (102), a holding device (106) for holding the at least one string (102), an electrically or electronically operated exciting device (116,116?) for contactlessly exciting of the at least one string (102), a sounding body (108) for acoustically radiating oscillations of the string and an interface (113) for supplying a signal to the exciting device (116, 116?), wherein the signal is produced independently from the at least one string (102). The exciting device (116, 116?) enables exciting oscillations of the string of a sufficiently large amplitude so that the sounding body (108) can radiate tones of a loudness which is at least in the range of known acoustical string instruments. For transferring the string's oscillations to the sounding body (108), a bridge (112) is arranged between the sounding body (108) and the at least one string (102) .
