A device for amplifying weak microphone signals, characterized in that in the mobile membrane of an earphone or the cone of a loudspeaker, an axis is arranged which, at the opposite end, is connected to the mobile membrane of a microphone. When moving the first one because of a signal applied from another microphone, it moves directly to the second one by means of the axis that joins them, resulting -as it is a direct attack- increased the power that was in the headset or loudspeaker. This increased power can be further multiplied if another identical system is then coupled. (Machine-translation by Google Translate, not legally binding)
