Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO DE EMISION DE ONDAS ACUSTICAS DE EMISION DE ONDAS ACUSTICAS DE MUY BAJA FRECUENCIA DE FUERE POTENCIA Y TRANSDUCTORES CORRESPONDIENTES.EL SECTOR TECNICO DE LA INVENCION ES EL DE LA REALIZACION DE TRANSDUCTORES ELECTROACUSTICOS PARA LA EMISION DE ONDAS ACUSTICAS EN INMERSION EN UN LIQUIDO. UN TRANSDUCTOR SEGUN LA INVENCION COMPRENDE UNO O VARIOS MOTORES ELECTROACUSTICOS (1) COLOCADOS SEGUN UN MIMO PLANO, EN EL INTERIOR O EN CORONA PERIFERICA DE UNA ENVOLTURA FLEXIBLE (5), DE LA CUAL SON SOLIDARIOS POR AL MENOS UNO DE SUS EXTREMOS POR OTRO DISPOSITIVO DE EMBALAJE (2) Y A LA QUE TRANSMITEN SUS VIBRACIONES, DICHA ENVOLTURA FLEXIBLE ESTA EN CONTACTO CON DICHO LIQUIDO (4) QUE CONSTITUYE LA SUPERFICIE DE EMISION DE LAS ONDAS ACUSTICAS Y DE UNA FORMA TAL QUE LA AMPLITUD DE ESTAS VIBRACIONES SE AMPLIFICA EN UNA GAMA DE MUY BAJA FRECUENCIA; DICHA ENVOLTURA (5) COMPRENDE AL MENOS CUALQUIER ABERTURA (6) QUE DEJA DICHO LIQUIDO (4) PENETRAR EN CUALQUIER CAVIDAD (7) INTERIOR DELIMITADA POR DICHA ENVOLTURA (5); UN BAFLE (15) DE MATERIAL ALVEOLAR RESISTENTE A LA PRESION DE INMERSION OCUPA LA MAYOR PARTE DEL VOLUMEN DE LA CAVIDAD (7) , CUYA SUPERFICIE EXTERNA ESTA A UNA DISTANCIA CONSTANTE (14) DE LA DE LA ENVOLTURA (5), Y ES SOLIDARIA DEL DISPOSITIVO DE MONTAJE (2,8) DE LOS MOTORES ACUSTICOS.
