Abstract
UN DISPOSITIVO PARA REALIZAR FUNCIONES ELECTROACUSTICAS, QUE INCLUYE FUNCIONES DE ANULACION DEL RUIDO, AYUDA A LA ESCUCHA, INTERFAZ DE TRANSMISION, CASCOS TELEFONICOS, ALIMENTACION PARA DISPOSITIVO DE GRABACION Y AURICULARES. EL DISPOSITIVO INCLUYE TRANSCONDUCTORES COMPUESTOS CONECTADOS A UNA UNIDAD DE CONTROL. LOS TRANSCONDUCTORES COMPUESTOS SE PUEDEN MONTAR SOBRE UNA BANDA DE CABEZAL Y ESTAN CONFIGURADOS PARA INCLUIR TRANSCONDUCTORES DE ENTRADA PARA CONVERSION DE LAS ONDAS ACUSTICAS EN SEÑALES ELECTRICAS PARA PROCESAMIENTO POR UNA UNIDAD DE CONTROL, Y TRANSCONDUCTORES DE SALIDA PARA CONVERSION DE LAS SEÑALES ELECTRICAS PROCESADAS EN ONDAS DE SONIDO PROCESADAS. LA UNIDAD DE CONTROL INCLUYE UN INVERSOR/AMPLIFICADOR Y UN MEZCLADOR/AMPLIFICADOR DE SALIDA PARA INVERSION DE LA ENTRADA ELECTRICA Y CONTROL DE LA GANANCIA, BIEN SEA PARA AJUSTAR LA GANANCIA PARA MEJORAR UNA FUNCION DE ANULACION DE RUIDO, O INCREMENTO DE LA GANANCIA MAS ALLA DEL NIVEL MINIMO ESCUCHADO POR EL OIDO HASTA UN NIVEL DESEADO PARA UNA FUNCION DE AYUDA A LA ESCUCHA. SE PROPORCIONAN CONECTORES PARA CONEXION DE GRABADORAS Y UN MICROFONO DE BRAZO, Y SE FACILITAN CONMUTADORES DE SELECCION DE FUNCION POR LOS MEDIOS DE CONTROL, PARA CONEXION DE COMPONENTES DE CIRCUITO DE LA UNIDAD DE CONTROL SELECTIVAMENTE PARA EJECUCION DE LAS FUNCIONES ANTERIORES. LOS TRANSCONDUCTORES DE ENTRADA Y SALIDA TIENEN DIAFRAGMAS ORIENTADOS EN SENTIDO OPUESTO, EN UN PLANO COMUN, PARA PROPORCIONAR UNA ONDA ACUSTICA INVERSA EN TIEMPO REAL, PARA COMBINACION CON, Y ANULACION SUSTANCIALMENTE DE, UNA ONDA ACUSTICA ENTRANTE. EN ESTA PRESENTACION DEL INVENTO, SE PUEDE INCORPORAR IGUALMENTE UNA PARED DE AISLAMIENTO, PARA IMPEDIR QUE EL SONIDO DEL TRANSCONDUCTOR DE SALIDA TENGA PROPAGACION DE RETORNO EN EL TRANSCONDUCTOR DE ENTRADA. EN UNA SEGUNDA PRESENTACION DEL INVENTO, LOS TRANSCONDUCTORES DE ENTRADA Y SALIDA ESTAN AMBOS ORIENTADOS EN LA MISMA DIRECCION HACIA EL CANAL DE AUDICION DEL USUARIO.
