Following the novel introduced concept of the active carriers, this paper brings forward a technique toward the manipulability of an internally piezo-equipped active spherical carrier subjected to the progressive acoustic plane waves as the handling contactless asset. It is assumed that the piezoelectric part of the active carrier may be actuated as a bi-sectional body (i.e., two continuous hemispherical parts), with prescribed phase difference, and the polar position of the imaginary separating plane may be altered. This issue brings about an asymmetry in the dynamics of the problem which leads to emergence of position/frequency dependent acoustic radiation torque. It is obtained that as the carrier is excited by imposing harmonic voltage with the same amplitude and a π-radians phase difference, the zero-radiation force situation is obtained for a specific amplitude and phase of voltage as a function of frequency. This situation is treated as a criterion to determine the optimal amplitude of operation voltage. It is shown that the net force's direction exerted on the activated carrier may be steered along any desired orientation, assuming the fixed direction of incident wave field. The explained method of excitation and controllability of the spatial position of the divisor plane can possibly be a breakthrough in acoustic handling of active carriers. Noticeably, by this new technique, the single beam acoustic based contact-free methods and their applications in association with the concept of active carriers are now one step forward.

主动球形载体的声学转向

遵循新引入的有源载体概念，本文提出了一种技术，该技术可用于处理作为处理非接触式资产的内部压电式有源球形载体，该载体受到渐进声平面波的影响。假设有源载体的压电部分可以作为具有规定相位差的二等分体（即两个连续的半球形部分）被致动，并且可以改变假想分离面的极性位置。这个问题会导致问题的动力学不对称，从而导致出现位置/频率相关的声辐射扭矩。得到当载波被施加相同幅度和 π 弧度相位差的谐波电压激励时，零辐射力情况是针对特定幅度和相位的电压作为频率的函数获得的。这种情况被视为确定工作电压最佳幅度的标准。结果表明，假设入射波场的方向是固定的，施加在激活载体上的合力方向可以沿着任何所需的方向转向。所解释的除数平面空间位置的激励和可控性方法可能是有源载流子声学处理的突破。值得注意的是，通过这项新技术，基于单波束声学的非接触方法及其与有源载体概念相关的应用现在向前迈进了一步。这种情况被视为确定工作电压最佳幅度的标准。结果表明，假设入射波场的方向是固定的，施加在激活载体上的合力方向可以沿着任何所需的方向转向。所解释的除数平面空间位置的激励和可控性方法可能是有源载流子声学处理的突破。值得注意的是，通过这项新技术，基于单波束声学的非接触方法及其与有源载体概念相关的应用现在向前迈进了一步。这种情况被视为确定工作电压最佳幅度的标准。结果表明，假设入射波场的方向是固定的，施加在激活载体上的合力方向可以沿着任何所需的方向转向。所解释的除数平面空间位置的激励和可控性方法可能是有源载流子声学处理的突破。值得注意的是，通过这项新技术，基于单波束声学的非接触方法及其与有源载体概念相关的应用现在向前迈进了一步。假设入射波场方向固定。所解释的除数平面空间位置的激励和可控性方法可能是有源载流子声学处理的突破。值得注意的是，通过这项新技术，基于单波束声学的非接触方法及其与有源载体概念相关的应用现在向前迈进了一步。假设入射波场方向固定。所解释的除数平面空间位置的激励和可控性方法可能是有源载流子声学处理的突破。值得注意的是，通过这项新技术，基于单波束声学的非接触方法及其与有源载体概念相关的应用现在向前迈进了一步。
