Paper Abstract

In this paper, recent efforts conducted to analyze the dynamic behavior of a biology-inspired miniature directional microphone are presented. Inspired by the tiny ears of the fly Ormia, the proposed directional microphone consists of two circular diaphragms coupled by a beam. The numerical study has shown that the biology-inspired directional microphone enables the amplification of the time delay between the sound pressure induced displacement responses of the two diaphragms. Factors such as the beam stiffness and the air backed cavity, which influence the performance of the directional microphone, are investigated. These analyses and results are expected to be valuable for the development of biology-inspired miniature directional microphones for various applications.
