The purpose of this experiment is to realize the binding and movement of light and small objects inthe air by using acoustic principles. First of all, based on the analysis of the experimental principle. theexperimental scheme is designed , three experimental devices are made , and relevant experimenta. studies arecarried out; Secondly,on the basis of experimental research the Comsol simulation software is used to simulatethe sound pressure level image and fluid particle capture animation , and the simulation results are displayed:Finally ,through the comparison of theoretical , experimental and simulation results ,the experimental results areeffectively discussed.
