Abstract
ESTE APARATO ESTA PREVISTO PARA SU EMPLEO EN TELEFONOS Y TIENE UN MICROFONO Y UNA CAPSULA DE AURICULAR. EL MICROFONO Y EL AURICULAR SE DISPONEN EN SOPORTES DE CAPSULA QUE TIENEN CIERTA DISTANCIA ENTRE SI Y ESTAN ACOPLADOS ENTRE SI MEDIANTE ELEMENTOS DE UNION. EL SOPORTE DE CAPSULA DEL AURICULAR CONFORMA UNA SUPERFICIE DE REFERENCIA, QUE PUEDE DISPONERSE EN UN ANGULO DE TAL MODO QUE SE PRODUCE UN INCREMENTO DE DISTANCIA RESPECTO A UN EJE LONGITUDINAL, PARTIENDO DE LA SUPERFICIE DE REFERENCIA EN DIRECCION HACIA EL MICROFONO. EL MICROFONO SE CONFORMA COMO UN MICROFONO ORIENTABLE, CUYAS RANURAS TRASERAS SE DISPONEN DE TAL MODO QUE SE PRODUCE UNA CARACTERISTICA DE ORIENTACION HACIA LA BOCA HUMANA SIN OSCILACIONES MECANICAS. EN EL SOPORTE DEL MICROFONO, SE PREVEN UNAS ABERTURAS DE TRANSICION ACUSTICA EN UNA ZONA DE LA PARED DE DELIMITACION. EN LA ZONA DEL PABELLON DEL MICROFONO SE EXTIENDE UN REBORDE QUE SE ELEVA POR ENCIMA DEL PABELLON Y QUE CIRCUNDA EL MICROFONO POR TRAMOS. ESTE REBORDE SE INTERRUMPE EN LA ZONA DE UNA DIRECCION QUE NO ENCARA EL MICROFONO. AL MENOS UNA PARTE DE LAS ABERTURAS DE TRANSICION ACUSTICA SE ORIENTA EN UNA DIRECCION PARALELA A LA NORMAL DEL PABELLON Y LA OTRA PARTE DE LAS ABERTURAS SE ORIENTA TRANSVERSALMENTE RESPECTO A LA NORMAL.
