| Abstract(in English) | The parasitoid fly Ormia ochracea shows a remarkable ability to detect the direction of an incident sound even though its acoustic sensory organs are in very close to each other, where the interaural differences in intensity and time can be extremely small. In this paper, we discuss a micro sound source localization sensor with mimicking the unique auditory organ of the fly. First, we show its key structures are 1) a center supported diaphragm, 2) an enhancement mechanism to reversed-phase vibration. Next we propose a gimbal diaphragm to realize these structures. Finally, we show our fabricated sensor and experimental results. |
