Abstract
CONSTA DE UN PRIMER GRUPO DE TRANSDUCTORES (7 A 10) DISPUESTOS DE ACUERDO CON UNA PRIMERA LINEA Y ALIMENTADOS POR UNA SEÑAL "DERECHA" DE UNA CADENA DE ALTA FIDELIDAD, ASI COMO DE UN SEGUNDO GRUPO DE TRANSDUCTORES (11 A 15) DISPUESTOS DE ACUERDO CON UNA SEGUNDA LINEA, FORMANDO UN ANGULO CON LA MENCIONADA PRIMERA LINEA, Y ALIMENTADOS POR UNA SEÑAL "IZQUIERDA". LAS SEÑALES "DERECHA" E "IZQUIERDA" QUE ALIMENTAN A LOS GRUPOS DE TRANSDUCTORES (7 A 10 Y 11 A 15) ESTAN EN FASE Y EL CAMINO ("A" A "E") QUE SEPARA LAS ZONAS ACTIVAS DE DOS TRANSDUCTORES ASOCIADOS (6,11;7,12;8,13;9,14;10,15) ES IGUAL A UN MULTIPLO IMPAR DE LA SEMILONGITUD DE ONDA DE UNA FRECUENCIA COMPRENDIDA ENTRE 300 Y 1000 HZ, CREANDO ASI UN ACOPLAMIENTO ACUSTICO PARA ESTA FRECUENCIA ENTRE AMBOS TRANSDUCTORES. LAS FRECUENCIAS DE ACOPLAMIENTO DE LOS DIFERENTES PARES DE TRANSDUCTORES SON DIFERENTES.
