RESONANCE PART OF STRINGS

PROBLEM TO BE SOLVED: To provide a resonance part capable of producing a sentimental feeling as a music generating means. SOLUTION: The resonance part is constituted by opposingly and attachably/ detachably providing films 2, 3 at both edges of a hollow frame 1 and providing a linking member 5 consisting of a solid object to be placed inside the frame and held like a bridge by being in tight contact with inside of the both of opposed films 2, 3. While linkage between central planes of opposed vibrating members (the films 2, 3) is performed by an echoic means by gas in the conventional case, the linkage is made to be performed by the linkage by the solid object and a propagating means here by this structure.
