20.500.12556/RUL-127421 Analiza in nadgradnja avtomobilskega avdio sistema Analysis and upgrade of car sound system Zaradi želje po boljši vozniški izkušnji v tej zaključni nalogi obravnavamo proces nadgradnje osnovnega avtomobilskega avdio sistema, katerega glavna pomanjkljivost je bila nezadovoljiva akustična zmogljivost, z zmogljivejšim sistemom. Teoretičnemu opisu posameznih vgrajenih komponent v vozilu potrebnih za uspešno delovanje avtomobilskega avdio sistema sledi pregled trenutnega avdio sistema ter obravnava njegovih pomanjkljivost. Temu sledi primerjava med za izbrano vozilo ustreznimi avdio sistemi, ki so ponujeni na tržišču in izbira najboljšega med njimi. Po opisu procesa vgradnje sistema in programskega kodiranja sistema na vozilo je izvedena še primerjava akustičnih zmogljivosti prvotnega avdio sistema z nadgrajenim, kjer pri slednjem opazimo izboljšane akustične zmogljivosti predvsem v območju nižjih frekvenc. Na koncu poskusimo s spreminjanjem nastavitev izenačevalnika sistema merjeni zvok približati krivulji idealnega frekvenčnega odziva, pri čemer smo deloma uspešni. Due to the desire for a better driving experience this final paper focuses on the process of upgrading the basic car audio system whose main deficiency was unsatisfactory acoustic performance with a more powerful system. A theoretical description of the individual in-vehicle components required for the successful operation of the car audio system is followed by an overview of the current audio system and a discussion of its shortcomings. This is followed by a comparison between the appropriate audio systems available on the market for the selected vehicle and the selection of the best among them. After describing the process of installing the system and software coding of the system on to the vehicle, a comparison of the acoustic performance is performed between the original and upgraded audio system where we can see a significant improvement especially in the area of lower frequencies. In the end, we try to change the systems equalizer settings so that the measurement would be closer to the ideal frequency response curve, which we partially succeed in doing. akustika avdio sistem frekvenčni odziv nadgradnja ojačevalec zvočnik acoustics amplifier audio system frequency response speaker upgrade true false false [L.
