Abstract

UN DISPOSITIVO ADAPTADOR DE IMPEDANCIA ACUSTICA. COMPRENDE UNA REJILLA DE FIBRAS QUE TIENE UNA IMPEDANCIA ACUSTICA RELATIVAMENTE BAJA Y ESTA EMPOTRADA EN UNA CAPA DE RESINA DE PLASTICO. LA RESINA PUEDE CARGARSE CON UN POLVO METALICO DE ALTA DENSIDAD, EL CUAL PUEDE DEPOSITARSE CONTRA LAS FIBRAS DE LA MALLA PARA PRODUCIR UNA CAPA DE ALTA IMPEDANCIA ACUSTICA QUE TIENE VARIACIONES DE ESPESOR CASI PERIODICAS Y QUE VA EMPOTRADA DENTRO DE LA CAPA DE RESINA MAS GRUESA. LA ESTRUCTURA PUEDE FORMARSE MEDIANTE UNA OPERACION DE COLADA QUE NO REQUIERE MATICES DE PRECISION Y QUE POR TANTO SE PRESTA A UNA FABRICACION ECONOMICA DE LOS TRANSDUCTORES.
