摘要： An electromagnetic transducer having a diapragm (11) on at least one face of which there is an audio-frequeny current conductor (15). The conductor (15) is arranged in a wave form pattern to divide the diaphragm (11) into a plurality of acoustically rigid zones (17) and define current paths (16) along the sides of the zones (17). An array of magnets (21) is arranged to produce a magnetic field orthogonal to each current path (16) whereby interaction between the magnetic fields and an audio-frequency current passing along the current paths (16) effects vibration of the diaphragm (11).

摘要： Un transducteur électromagnétique possède un diaphragme (11); sur au moins une face de celui-ci, l'on trouve un conducteur de courant de fréquence acoustique (15). Le conducteur (15) est agencé en une configuration de forme d'ondes pour diviser le diaphragme (11) en une pluralité de zones acoustiquement rigides (17) et définir des chemins de passage de courant (16) le long des côtés des zones (17). Un réseau d'aimants (21) est prévu pour produire un champ magnétique orthogonal à chaque chemin de passage de courant (16) de sorte qu'une interaction entre les champs magnétiques et un courant de fréquence acoustique passant le long des chemins de courant (16) fait vibrer le diaphragme (11).

摘要： An acoustic diaphragm comprises a core 11 disposed between a pair of skin members 13. The core is concentrically corrugated to have alternately slanting portions converging to concentric lines 21. Each skin member 13 is bonded to the core at the concentric lines on the respective face of the core. The core is preferably formed from sheet material folded along the concentric lines. Radial reinforcing ridges 17 may also be provided. A method of manufacturing the acoustic diaphragm is also disclosed.
