Abstract: PURPOSE:To set sound quality artificially and freely at a bass-side string support part by forming spaces inside nearby a vibration transmission part from bass- side strings in the plate-thickness direction. CONSTITUTION:In the wooden back lid 1 for the musical instrument which has the vibration transmission part where vibrations from plural strings are transmitted, the spaces 5 are formed in the plate-thickness direction nearby the vibration transmission part from the bass-side strings among strings. In this case, the spaces 5 are formed in the plate-thickness direction of the back lid 1, so a characteristic equivalent to the strength to the shearing deformation of the internal layer part of the back lid, i.e. a coefficient of transverse elasticity decreases. Therefore, timbre-relative material property which is the ratio of the coefficients of longitudinal elasticity and transverse elasticity of the back lid 1 increases, and consequently the internal friction loss in a high frequency band at the time of back lid driving increases and a warm woody sound is realized. Then the spaces 5 are provided only nearby the vibration transmission part from the bass-side strings among the strings, so the sound quality of the bass range is improved. Consequently, sound quality balance among respective sound ranges can be set in the best state.
