摘要：An acoustic transducer comprising a light weight diaphragm is disclosed in whichthe internal vibrational resonant modes of the diaphragm are prevented or blockedwithout damping effects by mounting of the diaphragm on a rigid base parallel theretoby means of a multiplicity of similar parallelograms with flexible corners having
dynamically rigid sides the lengths of which are a small part of the wavelength therein ofthe highest frequency acoustic waves to be transduced with no two adjacent
parallelograms being spaced from each other by a distance which is more than a smallpart of the wave length in the diaphragm of the highest frequency acoustic waves to betransduced. Preferred embodiments are described in which the diaphragm is divided intoelements by the parallelograms with the individual elements made rigid by means otherthan the materials used, for example, by providing appropriate shape or tension in suchelement.
