Abstract

UN ALTAVOZ TRANSDUCTOR TIENE UNA BOBINA 5 Y UNA BOVEDA METALICA 11 CON UN ZOCALO 13 DISPUESTO CONCENTRICAMENTE EN UNA ZONA MAGNETICA ENTRE BARRAS 2 Y 4. EL ZOCALO 13 SE ACOPLA INDUCTIVAMENTE A LA BOBINA 5 PERO ES MECANICAMENTE INDEPENDIENTE AL TUBO FORMADOR DE LA BOBINA 6. EL TUBO 6 SE CONECTA AUN CONO DE BAJA FRECUENCIA PRINCIPAL 9 Y A UN CONO ADICIONAL Y POCO CONCENTRICO 16. UN ELEMENTO FIJO 14 QUE PROVEE CORRECCION DE FASE Y/O CARGA DE CUERNO ESTA FIJO A LA PALANCA CENTRAL 4 EN FRENTE DE LA BOVEDA 11 Y DENTRO DEL TUBO 6. EL MIEMBRO 14 Y TUBO 6 COOPERAN ACUSTICAMENTE.
