Abstract

Динамичен преобразовател с трептяща бобина съдържащ магнитен кръг, мембрана, към която е закрепена трептящата бобина, акустични елементи, представляващи съвкупност от тръба, празно пространство и акустични съпротивления, свързани към мембраната посредством въздушна възглавница, характеризиращ се с това, че акустичните елементи са оформени във възел, независим от магнитния кръг и мембраната. Патентните претенции са формулирани в 4 точки.A voice coil dynamic transducer comprising a magnetic circuit, a membrane to which the voice coil is attached, acoustic elements consisting of a tube assembly, void space and acoustic resistances connected to the membrane by means of an air cushion, characterized in that the acoustic elements are formed in node independent of the magnetic circuit and the membrane. The patent claims are formulated in 4 points.
