Abstract

"ESTRUTURA DE FONE DE OUVIDO COM UM CAMPO SONORO COMPOSTO". é descrita uma estrutura de fone de ouvido incluindo uma ou mais câmaras compostas. Cada uma das câmaras compostas inclui sub alto-falantes. Os sons gerados por estes sub alto-falantes são uniformemente distribuídos na câmara composta e um campo sonoro composto é gerado por estes sub alto-falantes. O campo sonoro gerado por cada um destes sub alto-falantes pode ser ajustado por meio da realocação da posição dos sub alto-falantes, por exemplo, através da realocação dos sub alto-falantes em diferentes ângulos, para gerar um campo sonoro composto. O campo sonoro gerado pelo alto-falante principal e o campo sonoro gerado por estes sub alto-falantes pode formar um som espacial com uma qualidade muito boa. Através do uso das características físicas dos locais destes sub alto-falantes, o som gerado pelo fone de ouvido apresenta uma pressão sonora de difusão uniforme e um efeito surround, os quais permitem ao usuário apreciar um campo sonoro similar ao de um cinema.
