发明名称 MAGNET SYSTEM FOR AN ELECTROACOUSTIC TRANSDUCER
摘要 <p>PHN 9628 10 An electroacoustic transducer comprising a diaphragm provided with conductors and 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 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 field in the plane of the diaphragm, so that a stronger magnetic field is obtained at the location of the conductors.</p>
