ABSTRACT:
A method of continuously making a composite tape transducer consisting of the steps of electrically charging dielectric layers on opposite sides of a conductive inner strip to form electrets, applying wider outer laminates symmetrically to opposite sides of the electret-covered inner strip and sealing together the marginal edge portions of the outer laminates to enclose the electret-covered inner strip.
