Abstract

Cilj ovog rada bio je napraviti osnovna mjerenja na zvučnicima. U prvom poglavlju opisivalo se zvučnike i njihovu podjelu. U drugom su poglavlju opisane sažete norme mjerenja na zvučnicima. Treće poglavlje predstavlja sama mjerenja. Mjerila se električna impedancija tri različita zvučnika u ovisnosti o frekvenciji. Na trećem su se zvučniku provela mjerenja osjetljivosti zvučnika i korisnost na trima frekvencijama: 100 Hz, 1 kHz, 10 kHz. Također mjerila se usmjerna karakteristika navedenog zvučnika na istim frekvencijama te se prikazala na polarnom dijagramu.

Abstract (english)

The aim of this thesis was to take basic measurements on loudspeakers. The first chapter describes the loudspeakers and their division. The second chapter describes concise measurement standards on speakers. The third chapter presents the measurements themselves. The input electrical impedance of three different speakers as a function of frequency was measured. On the third speaker, measurements of speaker sensitivity and utility were performed at three frequencies: 100 Hz, 1 kHz, 10 kHz. The directional characteristic of considered speaker at the same frequencies was also measured and displayed on a polar diagram.
