Description
Istniejace membrany glosnikowe (np. w ksztalcie stozka, wykonanego z papieru, lub innego podobnego materjalu) posiadaja wlasne okresy drgan. Przy emisji drgan przez glosnik tony, wlasciwe stozkowi, sa mocniej zaakcentowane, przez co znie¬ ksztalca sie wytwarzanie drgan glosniko¬ wego wibratora.Wynalazek niniejszy dotyczy membra¬ ny glosnikowej, w której braki te sa usu¬ niete przez zastosowanie wgniecen lub przeciec materjalu membrany. Wgniecenia, naciecia lub przeciecia mater jalu stozka naruszaja jego spoista calosc, zmieniaja jego sprezyste wlasciwosci, co za soba po¬ ciaga calkowite usuniecie niektórych wla¬ snych tonów membrany oraz obnizenie cze¬ stotliwosci pozostalych. Przeciecia te mo¬ ga byc wieksze lub mniejsze o rozmaitym rysunku.Zalaczony przy niniejszym rysunek u- widocznia tytulem przykladu postac wy¬ konania wynalazku na membranie ksztaltu stozka. Rys. fig. 1 przedstawia widok membrany zboku, rys. fig. 2 — zprzo- du.Wykonane szczeliny a, a (fig. 1 i fig. 2) sa zaklejone lub zaszyte waskiemi pasem¬ kami 6, b (fig. 1 i fig. 2) jakiegos podatne¬ go materjalu. Jako cialo podatne mozna zastosowac skóre, gume lub inne podobne mater jaly. PLExisting loudspeaker membranes (e.g. conical-shaped, made of paper or other similar material) have their own oscillation periods. When the vibration is emitted by the loudspeaker, the tones inherent in the cone are more pronounced, thereby distorting the vibration production of the loudspeaker vibrator. The present invention relates to a loudspeaker membrane in which these deficiencies are removed by the use of dents or cuts in the membrane material. . Dents, cuts or cuts in the core material of the cone disturb its cohesive whole, change its elastic properties, which entails the complete removal of some of the membrane's own tones and a reduction in the frequency of the remaining ones. These cuts may be larger or smaller in a variety of drawings. The drawing provided here shows by way of example an embodiment of the invention on a cone-shaped diaphragm. Fig. 1 shows a view of the diaphragm of the slope, Fig. 2 - in front. 2) of a compliant material. Leather, gum or other similar materials may be used as the compliant body. PL
