To even out the frequency curve, the air gap behind the diaphragm connects with a second air gap inside the capsule via coupling channels in conjunction with the formation of a defined flow resistance. For this purpose, the coupling channels are formed between a carrier part and a cover plate through the formation of slits. These slits are formed in the parting seam by groove-like cutouts disposed in the sheathing of the carrier part and by the correspondingly assigned cover plate.
