Abstract
An acoustic transducer comprises a transducer substrate, and an aperture having a non-circular perimetral shape defined through the transducer substrate. A diaphragm is disposed on the transducer substrate and coupled to a surface of the transducer substrate via at least one diaphragm anchor such that a gap is defined between the diaphragm and the transducer substrate, and an outer periphery of the diaphragm extends radially outwards of a rim of the aperture such that a portion of the diaphragm overhangs the aperture.
