利用声源和反射器之间产生的驻波场，可以在空气中声压分布的节点处捕获小物体。本文通过实验测量和数值计算两种方法研究了平面和凹面反射器下的声场。计算结果与实验数据吻合较好。在实验中，25.0mm直径的声源与凹面反射器之间产生的最大力为0.8mN。将直径为2.0mm的钢球悬浮在空气中的声场中。
Using a standing-wave field generated between a sound source and a reflector, it is possible to trap small objects at nodes of the sound pressure distribution in air. In this study, a sound field generated under a flat or concave reflector was studied by both experimental measurement and numerical calculation. The calculated result agrees well with the experimental data. The maximum force generated between a sound source of 25.0 mm diameter and a concave reflector is 0.8 mN in the experiment. A steel ball of 2.0 mm in diameter was levitated in the sound field in air.
