I'm not sure I damaged something: when I phone, on the other side my voice is well received, besides I re-tried to insert (extremely slowly and carefully) the pin inside both the bottom holes and it find something hard at the same depth, so it seems that nothing has been perforated.... but, I really would like to know where to find technical schematics or tear down videos to see how these two microphones are mounted and which is their function.
