摘要
采用超声波的相控阵聚焦技术,设计了一种球面等间距点声源阵。研究了此声源阵声场模拟计算理论,并对此阵的声场特性进行了仿真研究,模拟结果表明此声源阵对声波具有较好的聚焦效果,通过调整此声源阵的结构参数,可改善对声波的聚焦性能。
We have designed a spherical span array of point sound source using the technology of phased array focus with ultrasonic, studied the simulating computing theory of this sound source and done emulation research into its characteristics, and the simulation result shows that this sound source is good at sound wave focusing and can improve the focusing through adjustment of its structural parameters.
