Abstract:	摘要： This paper presents a physical analysis of the biomimetic microphone designed with a central-supported (C-S) diaphragm for the sound source localization. A clover-stem-like C-S design is proposed and achieving 47% improvement of net diaphragm displacement in comparison with the conventional C-S diaphragm design. The new design can effectively not only compensate undesired deformation of sensing diaphragm due to gravity and residual stresses but also make the diaphragm more flexible for better sound pressure sensitivity. 其他題名： JSEN 出版者： IEEE 出版日期： 2012-05-01 出處： IEEE sensors journal, 2012-05, Vol.12 (5), p.1504-1512 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 1530-437X 識別號： EISSN: 1558-1748 識別號： DOI: 10.1109/JSEN.2011.2173931 識別號： CODEN: ISJEAZ
