摘要
针对目前三维声操作技术悬浮粒子数量少、悬浮空间局限的问题,本文提出了一种由三对相对换能器阵列组成的声悬浮装置的设计方案,通过改变换能器阵列的相位差,成功实现了粒子的三维操纵.该装置可用于测量声速,相对误差一般在2%~5%左右,对测量环境要求比较严格.
Aiming at the problem of small number of suspended particles and limited levitation space in the current three-dimensional acoustic operation technology,a design scheme of acoustic levitation device composed of three pairs of opposed transducer arrays is proposed.By changing the phase difference of the transducer array,the three-dimensional manipulation of particles is successfully realized.This device can be used to measure the speed of sound with a relative error generally about 2%~5%,and the measurement should carry out under a relatively strict environment.
