From the angle of bionics of animal sonar system, this paper discusses the function of acoustie lens of the melon of Lipotes Vexillifer. Based upon the theory of the dome of underwater transducer we make the following suggestions: (1) the density (ρ) and the acoustic wave impedance of the melon can be changed so as to get the maximal transmission of energy for the emission of different kinds of signals. (2) the shape and the curvature of the. melon can be changed so as to get the necessary pattern of emitted...

From the angle of bionics of animal sonar system, this paper discusses the function of acoustie lens of the melon of Lipotes Vexillifer. Based upon the theory of the dome of underwater transducer we make the following suggestions: (1) the density (ρ) and the acoustic wave impedance of the melon can be changed so as to get the maximal transmission of energy for the emission of different kinds of signals. (2) the shape and the curvature of the. melon can be changed so as to get the necessary pattern of emitted beam in dolphins' locating, communicating and hunting activities. The sceond part of the paper describes the preliminary results of a measurement of the acoustic characteristics of a piece of the melon of Lipotes Vexillifer.

本文包括两部分。第一部分是从生物声纳仿生学角度,讨论了白暨豚声发射中,关于额隆的透声作用并从设计水声换能器导流罩全透射基本理论出发,提出两点设想: (1) 额隆的密度(ρ)可变,即波阻抗(Z=ρC)可变,以适应在发射不同类型信号时,都得到能量的最大传输。 (2) 额隆的形状可变,即曲率可变,以适应在定位、通讯,觅食中所需的发射方向特性。第二部分是对1980年2月1日至2月4日在我院消声水池(4×5×8M~3)中,对白暨豚额隆进行声学测量作出的初步服告。

This paper presents an acoustic structure model of free—flooded cylindrical transducer installed with holed end-caps.The ceramic tubes are sealed with epoxy resin in cylindrical shape. The coupling effect of vibration with regard to the liquid cavity and the cylinder is investigated by using electro-acoustic analogy circuit, the resonant frequencies of the transducer are calculated. In addition, the volume velocity ratio at the end-cap openings and on the cylindrical surface is also evaluated, and then the radiation pattern is computed. The results of theoretical calculation are conformable to the experimental data.
