| 中文摘要 | 本文讨论了边缘高斯型激发的换能器和菲涅尔换能器的声场特性。分析和计算结果表明，边缘高斯型激发的圆环源在很大的范围内轴上声压基本恒定，无极大极小起飞现象，在声轴上聚焦效果良好。文中还对菲涅尔换能器的聚焦声场特性进行了讨论。文中对1-3型压电复合材料的厚度模振动特性进行了分析，探讨了利用复合材料制作上述两种换能器的工艺方法。 |
| 英文摘要 | Author designes the edged-Gaussian-exited transducer and Fresnel transducer, and discusses their sound field characteristics. On the basis of calculations and measurements, It can be stated that the edged-gaussian-exited transducer has peak pressure on its axis which remains constant in a long distance. It has no maxima and minima in nearfield and has little diffraction in farfeild. In another case of non-uniformly exited transducer, the Fresnel focused transducer is studied in this paper, its structure perimeters and sound field characteristics are investigated. 1-3 composite material properties relevant to thickness-mode oscillations is analysed. The method of manufacturing transducers using inhomogeneous 1-3 piezo/epoxy composites was illustrated in detail. |
