Abstract

"RADIOTELEFONE". Um radiotelefone tendo um guia de onda acústico para canalização e direcionamento de energia sonora a um microfone formando uma parte do radiotelefone. O guia de onda inclui uma estrutura tubular alongada que varia em área de seção transversal de um terminal de entrada para um terminal de saída. Mais particularmente, o guia de onde é formado por uma estrutura de parede que inclui partes que tornam-se uma configuração de ondas. Estas configuração de ondas dá aumento a variação da área de seção transversal que é repetidamente encontrada entre as partes terminais de entrada e saída do guia de onda. A configuração do tipo de onda para o guia de onda forma um filtro acústico passa-baixo que propaga e transmite baixas freq³ências não ressonantes na faixa de 300 Hz a 3000 Hz.
