Abstract

"SISTEMA DE ALTO-FALANTE E MéTODO DE DIRIGIR ONDAS SONORAS". O alto-falante e método fornecem um acionador de um alto-falante que é móvel paralelo a uma direção de movimento para produzir ondas sonoras. Um refletor é montado em frente de um diafragma do acionador para refletir ondas sonoras do acionador. A direção do movimento ocorre em um ângulo agudo diferente de zero na horizontal ou em um plano de suporte externo que suporta o alto-falante.
