An elelctroacoustic transducer oomprising a diaphragm provided with conductors and magnetic zones at both sides of the diaphragm (5) for producing an energizing field at the location of the conductors (6). At the boundary areas of the magnetic zones (1, 2; 2, 3; 3, 4) auxiliary fields are produced in order to reduce stray fields at the location of the boundary areas (1, 2; 2, 3; 3, 4). This results in a better concentration of the energizing magnetic fields in the plane of the diaphragm (5), so that a stronger magnetic field is obtained at the location of the conductors (6). |
