Abstract

يتعلق الاختراع بعاكس صوتي (4) ، يتميز بكونه يتضمن هيكلا يضم عددا كبيرا من الدعامات (6) متباعدة عن بعضها البعض، متصلة بواسطة عارضات عديدة (5) متباعدة عن بعضها البعض ،يضم الهيكل المذكور على الاقل منطقة أولى لها تباعد أول بين العارضات ومنطقة ثانية على الأقل لها تباعد ثاني بين العارضات، مختلف عن التباعد الأول.The invention relates to an acoustic reflector (4), which is characterized by the fact that it contains a structure comprising a large number of struts (6) spaced apart, connected by several beams (5) spaced apart, the said structure comprises at least a first region having first spacing between the beams and At least a second has a second spacing between the models, different from the first spacing.
