板共振乐器是很多的,如提琴类拉弦乐器、琵琶等弹拨乐器都是。板共振乐器的音质优劣不仅与木材的结构及物理、机械、声学性能有关,更与板的厚度分布有关。譬如说制作提琴所用的木材及共鸣箱的形状和大小基本相同,而琴与琴之间音质的差别是相当大的, Plate resonant instruments are many, such as violin-type stringed instruments, pipa and other plucked instruments are. Sound quality of the board resonant instruments not only with the wood structure and physical, mechanical, acoustic properties, but also with the board thickness distribution. For example, the shape and size of the wood and resonance box used to make the violin are basically the same, but the difference in sound quality between the piano and the piano is quite large,
