| 摘 要： | 在模仿研究奥米亚棕蝇(Ormia ochracea)的听觉系统定位机制的基础上,提出一种新型的声定位装置及相应的定位理论。该仿生声定位结构的声感应部分包括三个弹性振膜,以及连接三个振膜的耦合杆等力学元件组成。对该结构的动态特性分析表明:声激励的入射方向同三个振膜的响应之间存在特定的关系,通过分析两者之间的对应关系,提出一种定位理论,该定位理论表明可通过检测并分析三个振膜的相应状况,计算得到声激励的入射角度。

| Abstract: | In this paper, a new type of instrument is designed for the purpose of localizing the sound source.It is a relatively compact structure.This bionic structure is to mimic the localization function of the ears of the parasitoid fly Ormia ochracea.It consists of three elastic diaphragms, three bars which are connected to the diaphragms, and some other mechanical components.Analysis of this structure's dynamic behavior shows that the incident angles of the sound have special relationship to the responses of this instrument, and the incident angles can be estimated by detecting the vibrations of the three elastic diaphragms. |
