Electret microphone

An electret microphone, comprising:

• an electrically conductive membrane;
• a counter-electrode having at least one first hole having a first distance from an edge of the counter-electrode and a second plurality of second holes each having a second distance from the edge of the counter-electrode, wherein the second distance is shorter than the first distance;
• a first electrically conductive coating directly on a first side of the counter electrode and a second electrically conductive coating directly on a second side of the counter-electrode, wherein the at least one first hole comprises a via in order to electrically contact the first and second electrically conductive coating, wherein at least a third distance is provided in each case between the second holes and the first electrically conductive coating so that the first electrically conductive coating does not reach as far as the second holes, and the second holes are isolated from the first conductive coating;
• and
• a polarizable film which covers the first side of the counter electrode and extends completely over the first electrically conductive coating and thereby leaves free the first and second holes.
