A microphone comprises a housing, a first and a second diaphragm, a first chamber, and a second chamber. A first and a second diaphragm, each having a first and second side, are provided in the housing. The first chamber is delimited at least partly by the first side of the first diaphragm and an inner surface of the housing. A first opening extends from the first chamber and to surroundings of the microphone. The second chamber is delimited at least partly by the first side of the second diaphragm and an inner surface of the housing. A second opening extends from the second chamber and to the surroundings. A common chamber is delimited at least partly by the second side of the first diaphragm, the second side of the second diaphragm and an inner surface of the housing. A third opening extends from the common chamber and to the surroundings.
