摘要： An acoustic transducer having the general form of a condenser microphone in which the natural resonant frequency of an edgesupported diaphragm is increased by connecting the diaphragm and backplate at places removed from the edge of the diaphragm with a liquid which is relatively immovable in response to high frequency impulses. The liquid is not resilient, but is dissipative of energy transferred thereto from the diaphragm at frequencies as low as only a few Hertz; at higher frequencies, it is functionally equivalent to a rigid connection.
