The acoustic radiation force has been extensively studied for static particles patterning and dynamic transportation. However, for better manipulation, there is strong demand for the dynamic manipulation of particles patterning, which has not been fully investigated. In this paper, the parametric bulk acoustic waves are proposed to realize the deformable dynamic patterning of multiple particles. The bulk acoustic waves exhibit the manipulation of multiple particles for different morphology, which can be separated or merged together to various length of line segments. Further, the line segments oscillate in form of rotation, which can be controlled to arbitrary angles. Most importantly, the deformable oscillation of nodal lines is dynamically manipulated. Multiple particles are trapped to deformable oscillation lines, then the lines bend and elongate periodically. This work paves the way for the control of complex functional acoustic field, thereby enabling the dynamic self-assembly for multiple particles.

声辐射力已被广泛研究用于静态粒子构图和动态传输。然而，为了更好的操纵，强烈要求动态操纵颗粒图案，这尚未得到充分研究。本文提出了参数化体声波，以实现多个粒子的可变形动态构图。体声波表现出针对不同形态的多个粒子的操纵，可以将它们分离或合并在一起以形成不同长度的线段。此外，线段以旋转的形式振荡，其可以被控制为任意角度。最重要的是，节点线的可变形振荡是动态操纵的。多个粒子被困在可变形的振荡线上，然后这些线会定期弯曲和拉长。这项工作为控制复杂的功能声场铺平了道路，从而实现了多个粒子的动态自组装。
