Percussion instrument with sound excitation letter to the clear toner magnitude of an exact clay

摘要

PROBLEM TO BE SOLVED: To provide bars which have timbre having bright and fast arriving characteristics and longer attenuation time with large sound volume and have distinct interval feels and consonance characteristics. ;SOLUTION: The longitudinal centers of the bars 2 are freely oscillatably supported by means of mounting screws 4 and the widths thereof are changed to regulate the ratio of the vibration frequency of the secondary vibration V1 of deflection vibration and the primary vibration t0 of torsional vibration to a relation of multiple of integer of V1:t0=1:2. Recessed parts 11 are formed at the ends of the rear surfaces to regulate the ratio of the vibration frequency of the secondary vibration V1 of the deflection vibration, the primary vibration t0 of the tosional vibration and the quaternary vibration V3 of the deflection vibration to a relation of multiple of integer of V1:t0:V3=1:2:3.;COPYRIGHT: (C)1998,JPO
