Abstract
ACOPLAMIENTO PARA MEJORAR EL ANCHO DE BANDA EN TRANSDUCTORES ELECTROACUSTICOS DE DIAFRAGMA METALICO. AL DIAFRAGMA METALICO (7) SE LE SELLA A SU ALREDEDOR UNA CAJA (17), QUE ENCIERRA UN DETERMINADO VOLUMEN DE AIRE Y QUE TIENE UN ORIFICIO (18), POR EL QUE SE RADIA LA ENERGIA ACUSTICA, DE UN TAMAÑO ENTRE LA MITAD Y UN OCTAVO DE LA SUPERFICIE EN QUE SE ENCUENTRA, CON LO QUE SE OBTIENE UN AUMENTO DE LA RESISTENCIA A LA RADIACION ACUSTICA DEL DIAFRAGMA (7). TAMBIEN SE PUEDE VARIAR LA FORMA DE LA CAJA (7), TERMINANDOLA EN BOCINA Y VARIANDO LAS DIMENSIONES.
