Abstract
EL TRANSDUCTOR DE EMISION ACUSTICA (4) PUEDE UTILIZARSE A LAS FRECUENCIAS RELATIVAMENTE BAJAS DESEADAS, ES RELATIVAMENTE PEQUEÑO Y RESULTA ECONOMICO Y FACIL DE FABRICAR. UN TRANSDUCTOR DE EMISION ACUSTICA (40) COMPRENDE UN DISCO DE BASE DE LATON (46). EL DISCO DE BASE (42) Y EL DISCO PIEZOCERAMICO (44) ESTAN DISPUESTOS COAXIALMENTE, Y SOLAMENTE LA REGION PERIFERICA ANULAR (54) DEL DISCO PIEZOCERAMICO (44) ESTA MONTADA EN UN SALIENTE ANULAR (48) QUE SE EXTIENDE AXIALMENTE DESDE EL DISCO DE BASE (42). EL SALIENTE ANULAR (48) ESTA PROVISTO DE ABERTURAS (52) PARA IMPEDIR COMPRESIONES EN UNA CAMARA (56) QUE AMORTIGUEN LAS VIBRACIONES DEL DISCO PIEZOCERAMICO (44). TAMBIEN, MEDIANTE LA MISMA CONSTRUCCION, SE PROPORCIONA UN OSCILADOR ELECTRICO.
