ABSTRACT:
An inertial transducer is provided comprising a housing containing therein a magnetic circuit including components thereof separated by a spring diaphragm wherein the flexing of the diaphragm causes the components to move toward and away from each other to induce a current in a coil. The spring diaphragm served to separate the housing into two tuned cavities, the frequencies of which differ from each other and from that of the spring diaphragm. The transducer has frequency response peaks at the resonant frequencies of the cavities and spring diaphragm.
