Abstract
EL ALTAVOZ COMPRENDE UNA UNIDAD DE BAJA FRECUENCIA QUE TIENE UN DIAFRAGMA CONICO TRASERO ACAMPANADO (21) Y UNA UNIDAD CONDUCTORA DE ALTA FRECUENCIA (27) SITUADA EN O ADYACENTE A LA RED DE DEL DIAFRAGMA CONICO DE BAJA FRECUENCIA, TAL QUE LOS CENTROS ACUSTICOS DE LAS DOS UNIDADES SEAN SUSTANCIALMENTE COINCIDENTES Y, PARA UN RANGO DE FRECUENCIA CRUZADAS EN EL QUE AMBAS UNIDADES CONDUCTORAS CONTRIBUYEN A LA SALIDA DE SONIDO SIGNIFICATIVA, LA DIRECCIONABILIDAD DE LA RADIACION DE SONIDO DE LA UNIDAD DE ALTA FRECUENCIA (27) ASI COMO LA CARGA ACUSTICA MEDIANTE EL DIAFRAGMA CONICO DE BAJA FRECUENCIA (21) ES SUSTANCIALMENTE ANALOGA A LA DE LA UNIDAD DE BAJA FRECUENCIA. UNA ESTRUCTURA MAGNETICA (28, 29, 30) PARA LA UNIDAD DE ALTA FRECUENCIA UTILIZA UN MAGNETO (29) FORMADO DE BORO ACERO NEODIMIUM QUE PERMITE QUE LA UNIDAD DE ALTA FRECUENCIA (27) SE POSICIONE DENTRO DE UN ROLLO CONDUCTOR (23, 24) DEL DIAFRAGMA DE BAJA FRECUENCIA MIENTRAS SE DISPONE DE UN VALOR ELEVADO DE FLUJO MAGNETICO.
