1. An electro-acoustic converter having an electrodynamic system comprising a pot magnet system having a core magnet and also a membrane carrying a plunger-type coil which oscillates freely in an annular gap of the pot magnet system, characterized in that the membrane (5) is clamped at its edge (6) between two pole iron parts (2, 9; 2a, 9) of the pot magnet system by the mutual magnetic forces of attraction between them, with the pole iron parts being centered relative to the axis of the pot magnet system (1). |
