Abstract

"FONE DE OUVIDO SEM RUìDO DE IMPULSO E BLOQUEIO EXTERNO". A presente invenção fornece um fone de ouvido sem ruído de impulso e bloqueio externo, que consiste de um alojamento de fone de ouvido possuindo uma câmara (41) acústica interna e um alto-falante (50) montado internamente, onde uma pluralidade das malhas (42) de saída de som é montada na extremidade frontal do alojamento (40) do fone de ouvido, e uma distância própria (8) é determinada entre a extremidade frontal do alojamento (40) do fone de ouvido e do alto-falante (50) montado internamente, onde uma pluralidade das malhas (43) de entrada de som é montada e circundam o alojamento (40) do fone de ouvido dentro da própria distância (8); e a extremidade de saída do ruído de impulso inferior de acordo com as duas extremidades de saída do alto-falante (50) é faceado pelas malhas (42) de saída do som; através do projeto. A presente invenção pode prevenir não somente o impacto direto do ruído de impulso ao ouvido, mas também os danos do tímpano e a perda de audição condutiva.
