ABSTRACT:
A pressure deformable body of a transducer is formed with a plurality of passage holes through which paths are established for a signal medium conducted thereto through a rigid base on which the body is mounted. Portions of the body material when loaded bulge into the passage holes causing constriction thereof to vary the intensity of the signal medium transmitted. The passage holes are spaced in an array arranged to distribute hole constriction in a load-pattern reproducing manner.
