  • Method for controlling wrinkles in a vibratile diaphragm
    Patent number: 4401858
    Abstract: A method and device for significantly improving the efficiency and sensitivity of an electroacoustical transducer. A relatively inelastic vibratile diaphragm is preformed to the shape of a mating backplate prior to the time it is actually mated to said backplate. By such preforming, the efficiency and sensitivity reducing effects from a wrinkled transducer diaphragm are minimized in that said wrinkles move to a diaphragm region where they have no effect on transducer sensitivity when the backplate is subsequently mated to said diaphragm.
