Akustična analiza zvočnih omaric : diplomsko delo - univerzitetni študij = Acoustic analysis of speaker enclosures : graduation thesis - university studiesHolcman, MihaelV nalogi smo raziskali vpliv MDF ter iverne plošče na akustične lastnosti zvočnih omaric. Najprej smo narejenim vzorcem izmerili dušilne lastnosti materiala, kjer smo raziskali tudi vpliv bitumna. ... Ugotovili smo, da ima MDF nižje dušenje kot iverna plošča. Nato smo iz obeh materialov izdelali zvočne omarice, kjer smo uporabili plošče debeline 12 mm, 19 mm, 22 mm in 28 mm. Narejenim omaricam smo z modalno analizo določili lastne frekvence stranic omarice. Omarice smo modelirali tudi z metodo končnih elementov in z modalno analizo ravno tako določili lastne frekvence stranic omarice. Ugotovili smo dobro ujemanje med izmerjenimi in izračunanimi lastnimi frekvencami stranic omarice. Omaricam smo določili tudi prenosne funkcije, kjer smo v omarice vgradili zvočniško enoto, s katero smo vzbujali stranice omaric. Na podlagi izmerjenih prenosnih funkcij omaric smo ugotovili, da omarica, narejena iz MDF plošče debeline 19 mm ustreza splošnim zahtevam zvočnih omaric in da za omarico takšnih dimenzij ni potrebe po stranicah večjih debelin.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
