摘要：
A portable electronic device having an outer case having a substantially planar face in which a microphone associated acoustic port is formed. The device also has a micro-electro-mechanical system (MEMS) microphone positioned within the outer case, the MEMS microphone having a diaphragm facing the microphone associated acoustic port. An acoustic mesh is positioned between the front face of the outer case and the diaphragm, the acoustic mesh having a non-linear acoustic resistance so as to minimize an effect of an incoming air burst on the diaphragm. Other embodiments are also described and claimed.
