在耳部距离很近、耳间强度和时间差异极小的情况下,寄生苍蝇对入射声源的方向具有显著的探测能力。本文模仿苍蝇独特的听觉器官,提出了一种带有万向节振膜的声源定位机构,实现了对声场引起的极小压力梯度的简单而优化的传递机构。我们用薄金属板制作了一个模型传感器,并通过实验证实了它对声源方向的定位。
The parasitoid fly Ormia Ochracea shows a remarkable ability to detect the direction of an incident sound even though its ears are in very close to each other, where the interaural differences in intensity and time are extremely small.In this paper, with mimicking the unique auditory organ of the fly, we propose a sound source localization mechanisms with a gimbal diaphragm which realizes a simple and optimal transduction mechanism for a very small pressure gradient caused by the sound field.We made a model sensor using a thin metal plate and confirmed that it localizes the direction of the sound source by experiments.
