Abstract

TRANSDUCTOR ACUSTICO, COMO UN CASCO TELEFONICO (2), QUE CONSTA DE UN ALOJAMIENTO CON UN RESPIRADERO (16) PARA VENTILAR EL MEDIO FLUIDO DEL ALOJAMIENTO. EL RESPIRADERO (16) ESTA DIMENSIONADO PARA GARANTIZAR QUE EL FLUJO LAMINAR DEL MEDIO FLUIDO SE MANTIENE A TRAVES DEL MISMO EN TODO EL ALCANCE UTIL DEL ACTIVADOR (14) DEL TRANSDUCTOR, DE MANERA QUE LA RESPUESTA DE AMPLITUD Y LA RESPUESTA DE FASE DE ESTE NO VARIAN SUBSTANCIALEMENTE EN ESE ALCANCE.
