However, the circuits where still working, because of another effect that was not anticipated, but stronger in the actual circuit. The '''capacitive effect''' of the two opposing coils. This capacitive effect can be made larger by providing a bigger overlapping area of the two conductors that form the microphonic surface. That simplified our print designs a little, because we were not forced to print coils as two port devices, but could use two rectangular shapes with a single port each. Leading to lesser connections and no jumper wires on our paper printed microphones. | However, the circuits where still working, because of another effect that was not anticipated, but stronger in the actual circuit.
