The paper presents a hybrid biomimetic directional microphone with a central floating pivot support by hybridizing the supersensitive ears of the parasitoid fly with the flexibility of the clover stalk.By introducing the mIIDpA, the mIPD, and the sensing region, the presented design with the state-of-the-art characteristics of mIIDpA 2.7dB/mm 2 and mIPD 155° has shown a highly potential application for the sound source localization with full space sensitivity.Excellence match between theoretical calculation and measurement results indicates the accuracy of the presented model and about 30% net diaphragm displacement improvement.
