| 声黑洞结构具备独特的声波捕获和聚焦能力, 已在许多声学领域展现出显著的应用优势和发展潜力. 目前, 声黑洞结构主要被应用于减振降噪, 而其在开发更强大超声振动器件方面的研究还相对有限. 基于此,开发了几种新型声黑洞功率超声振动系统, 包括声黑洞超声手术刀和声黑洞浸入式化学反应器. 通过在超声手术刀头设计中嵌入一维声黑洞轮廓, 显著提升了刀头的振动位移和声能辐射, 实现了更高效的手术切割和止血. 此外, 在浸入式声化学反应器的辐射头上引入声黑洞设计, 扩大了声空化区域并增强了辐射强度, 极大地提高了声处理效率. 总的来说, 声黑洞设计可以为高性能、高效率功率超声振动系统的开发提供创新方案, 同时在功率超声器件小型化方面具有独特的应用前景. |

| Acoustic black hole (ABH) structure exhibits distinctive capabilities in sound capture and focusing, offering significant advantages and potential for development in various acoustic fields. Currently, the ABH structure is primarily utilized for vibration reduction and noise suppression, with limited research on enhancing or developing more powerful ultrasonic vibration devices. In light of this, we have developed several innovative ABH power ultrasonic vibration systems, such as the ABH ultrasonic scalpels and ABH immersed sonoreactors. By incorporating a one-dimensional ABH profile into the design of the ultrasonic scalpel blade, we have notably enhanced the blade""s vibration displacement and acoustic energy radiation, resulting in more efficient surgical cutting and hemostasis. Furthermore, by integrating an ABH design into the radiator of the immersed sonoreactor, we have expanded the region of cavitation and increased radiation intensity to significantly improve acoustic processing efficiency. In conclusion, the ABH design offers novel solutions for advancing high-performance and high-efficiency power ultrasonic vibration systems while holding unique application prospects in miniaturizing power ultrasonic devices. |
