Abstract

A substantially flat diaphragm to be used in a sound transducer, characterized by being made up of a piece of stiff, resistant and cellular plate, which has a flat front face, a rear face and lateral faces that link said front face with said rear face, a layer including said front face, said prestressed layer being in a direction substantially perpendicular to the plane containing the front face and in a direction that is contained within the plane containing the front face and the remaining layers of said plate-shaped piece between said front face and said rear face, subjected to stresses that gradually decrease from said front face towards said rear face.
