摘要： A vibration plate for a music box having an improved tonal range and quality, yet with a reduced manufacturing cost. The vibrating reeds of the vibration plate are made smaller in width towards the highest frequency one of the reeds. Each of the reeds has a base portion and an end portion extending through a sloped portion from the base portion, the end portion being smaller in width than the base portion. The end portions of the reeds are arranged at equal intervals.
