Abstract
A planar dynamic sound transducer includes a magnet arrangement which for example comprises bar magnets and a fixing frame, and a diaphragm arrangement. The diaphragm arrangement has a tensioned diaphragm film (diaphragm for short), a tensioning device for the diaphragm, and a conductor structure applied to the diaphragm. When the conductor structure is conventionally provided with electrical connections mechanically sensitive connections and/or high transfer resistances often occur. An improved diaphragm arrangement for a planar dynamic sound transducer includes a support frame having at least one contacting surface, and a diaphragm tensioned on the support frame, and which at least one electrically conductive conductor track is applied by coating. At least one end of the conductor track applied by coating extends on to the contacting surface of the support frame. The connecting line can be connected to the contacting surface of the support frame by way of a solder join.
