Latest Patents
Carignan's latest patents include a method for controlling wrinkles in a vibratile diaphragm. This method and device significantly enhance the efficiency and sensitivity of an electroacoustical transducer. A relatively inelastic vibratile diaphragm is preformed to the shape of a mating backplate before being mated to it. This preforming minimizes the efficiency and sensitivity-reducing effects caused by a wrinkled transducer diaphragm. The wrinkles are directed to a diaphragm region where they do not affect transducer sensitivity when the backplate is subsequently mated to the diaphragm.
