ABSTRACT:
An electroacoustic transducer comprising a diaphragm provided with conductors and a magnet system having permanent magnetic zones at both sides of the diaphragm for producing an energizing field at the location of the conductors. At the boundary areas of the magnetic zones auxiliary magnetic fields are produced in order to reduce stray fields at the location of the boundary areas. This results in a better concentration of the energizing magnetic fields in the plane of the diaphragm so that a stronger magnetic field is obtained at the location of the conductors.
