Abstract

ESTA INVENCION SE REFIERE A UN ALTAVOZ DINAMICO QUE TIENE UNA POTENCIA DE SALIDA Y UNA DISTORSION ARMONICA SECUNDARIA PERFECCIONADA. LA REDUCCION DE LA DISTORSION ARMONICA SE ORIGINA COMO CONSECUENCIA DE UNA DISPOSICION DEL ESCUDO EN TIPO SANDWICH ALREDEDOR DEL POLO EMPINADO DEL ALTAVOZ. EL ESCUDO PROTEGE LA BOBINA DE VOZ DE LAS INTERACCIONES DE FLUJO MAGNETICO ASIMETRICAS CON UN HUECO DE AIRE ENTRE EL POLO Y LA PLACA. ESTO REDUCE LA DISTORSION SECUNDARIA ARMONICA DEBIDA A LA ASIMETRIA DEL BUCLE DE HISTERESIS MENOR FORMADO POR EL CAMPO MAGNETICO DE LA BOBINA DE VOZ ENERGETIZADA CON EL CAMPO MAGNETICO ESTATICO ACTUANDO SOBRE EL MATERIAL FERROMAGNETICO QUE FORMA EL POLO. ADICIONALMENTE, LA DISMINUCION DE LA REDUNDANCIA DEBIDA A LA LOCALIZACION DE LOS ELEMENTOS DE ESCUDACION NO -FERROMAGNETICOS PRODUCE UN INCREMENTO EN EL VOLUMEN.
