Abstract

Toto řešení ge vztahuje k oblasti elektroakustiky. Cílem řešení je zlepšení jakosti ozvučení volných prostorů a místností vytvořením ostřejší frekvenčně stabilizované směrové charakteristiky. Stanoveného cíle je dosaženo tím, že akustický vyzařovač obsahuje pátý a šestý vyzařovací prvek, které ve vertikální rovině společně s druhým a čtvrtým vyzařovacím prvkem tvoří soufázové dvojice.This solution ge refers to the area electroacoustics. The solution is to improve quality sound distribution of open spaces and rooms creating a sharper frequency stabilized directional characteristics. Established The goal is achieved by being acoustic the radiator contains the fifth and sixth radiant element that in a vertical plane together with the second and fourth radiating elements form soufázové dvojice.
