Electroacoustic transducer comprising, firstly, a low density volume supporting on its periphery at least one electrically conducting circuit through which passes an electric signal corresponding to the audible signal to be emitted and, secondly, magnets mechanically connected to said periphery. The magnets supply a magnetic field, with the field lines surrounding the conducting circuit(s) on said periphery. Several embodiments are described together with several methods of electrically coupling the electric signal emitting circuit to the conducting circuits.

La présente invention concerne un transducteur électro-acoustique comportant, d'une part, un volume de faible densité supportant sur sa périphérie au moins un circuit électriquement conducteur traversé par un signal électrique représentatif du signal sonore à émettre et d'autre part des aimants reliés mécaniquement à ladite périphérie. Les aimants fournissent un champ magnétique dont les lignes de champ entourent le ou les circuits conducteurs placés sur ladite périphérie. Plusieurs modes de réalisation sont présentés, ainsi que plusieurs modes de connexion électrique entre le circuit émetteur de signaux électriques et les circuits conducteurs.
