Abstract
An improved phonographic plate, characterized by the fact that it consists of a thin and flat spring of cardboard or plastic material or any material to which a covering is applied consisting of an emulsion of a material, plastic capable of being molded by pressure, so that receives the phonographic impression in a permanently invariable way, so that it is forming a single piece with the support that gives rise to the resonance of the unique mass established to a remarkable sonority in the sound performance.
