Abstract

A találmány tárgya eljárás hajlító hullámú rezgés rezonáns módusainalapuló akusztikus működésre szolgáló legalább egy elemhez (10)társított és vele működési kapcsolatban levő hajlító hullámú átalakító(20) elhelyezésére szolgáló legalább egy előnyös helyzetmeghatározásához, amely eljárás során az elemre (10) akusztikusenergiát bocsátanak és ezzel az elemben (10) akusztikailag relevánshajlító hullámokat keltenek a gerjesztett hajlító hullámú hatássalösszefüggő mérhető hatásoknak a hajlító hullámú átalakító (20)helyzetével változó hatásokat szisztematikusan meghatározzák, és aszisztematikus meghatározás eredményeiből meghatározzák az előnyöshelyzeteket. A találmány tárgya továbbá eljárás hangszóró készítésérea fentiek alkalmazásával. A találmány tárgya továbbá berendezés azeljárás foganatosítására. ÓThe subject of the invention is a method for determining at least one advantageous position for placing a bending wave transducer (20) associated with and operationally connected to at least one element (10) for acoustic operation based on the resonant modes of bending wave vibration, during which acoustic energy is emitted to the element (10) and thus the acoustically relevant bending waves are created in element (10), the measurable effects related to the excited bending wave effect, the effects varying with the position of the bending wave transducer (20), are systematically determined, and the advantageous positions are determined from the results of the unsystematic determination. The subject of the invention is also a method for making a speaker using the above. The subject of the invention is also a device for carrying out the method. HE
