The structure and method of manufacture of diaphragms for use in electronic body sound transducers is described. The diaphragm is a critical element in shaping the overall amplitude and frequency response of such transducers. Various embodiments of novel diaphragms are described, each of which offers particular advantages in shaping the transducer response and the mechanical or electrical characteristics of the diaphragms. Manufacturing steps for producing such diaphragms are also disclosed. The diaphragms can be used in any electronic body sound transducer, particularly capacitive, magnetic or optical transducers. Such diaphragms and transducers are applicable to the sensing of body sounds in electronic stethoscopes.
