Abstract

''PROCESSO DE CONEXãO DE UM MICROFONE, E, DISPOSIçãO PARA INTERFACE DE UM MICROFONE''. A presente invenção se refere a um processo e a uma disposição para conectar um microfone, requerendo uma tensão de polarização, a um dispositivo de áudio para estabelecimento de comunicações de sinais de voz entre eles, em que a interface compreende diversas entradas para o microfone. O processo da invenção compreende as etapas de fornecimento de uma tensão de polarização ao microfone através de pelo menos uma das referidas diversas entradas para o microfone, de modo que a tensão de polarização é conduzida através de um diodo, que é disposto em um respectivo dos condutos das referidas entradas, e transmissão do sinal de voz do microfone para o dispositivo de áudio através de outra entrada das referidas diversas entradas.'' MICROPHONE CONNECTION PROCESS, AND MICROPHONE INTERFACE PROVISION ''. The present invention relates to a method and arrangement for connecting a microphone, requiring a bias voltage, to an audio device for establishing voice signal communications between them, where the interface comprises several inputs for the microphone. The process of the invention comprises the steps of supplying a polarization voltage to the microphone through at least one of the said several microphone inputs, so that the polarization voltage is conducted through a diode, which is arranged in one of the respective conduits of said inputs, and transmission of the voice signal from the microphone to the audio device through another input of said various inputs.
