With a shown example of the pinned-pinned plate, a new piezoelectric sensor design is presented to measure volumedisplacement.
本文以工程常见四端位移为零的振动板为例，提出一种新的压电式传感器的设计方法测量体积位移。

Controlling the volumedisplacement of vibration plate has previously been shown to be a good strategy to reduce its overall sound radiation at low frequency.
控制振动板结构的体积位移是降低结构总声功率的一种有效策略。

This "displacement effect" is further heightened by the sheer volume of exhibits.
