Abstract

''DISPOSITIVO E PROCESSO PARA CAPTAçãO DE SOM EM UM COMUNICADOR DE VOZ''. A presente invenção relaciona-se a um guia de som (5) em um comunicador de voz, por exemplo um rádio móvel terrestre, um intercomunicador, um telefone sem fio ou um telefone móvel (1). Para obter boa qualidade sonora em tal telefone, é freq³entemente usada uma cobertura (3) que reflete a voz na direção do microfone (6) no corpo (2) do telefone. Arranjando um túnel de ar como um guia de som (5) na cobertura de ''encaixe'' rápido e deixando-o conduzir ao corpo do telefone e ao microfone, a qualidade de som é substancialmente melhorada. No sentido de evitar resposta de freq³ência irregular que ocorre inevitavelmente em tais guias de som, devido à formação de ressonância, material de atenuação do tipo convencional é usado dentro do guia de som, junto com a extinção acústica, utilizando mínimos de pressão como um ponto de localização para o microfone.
