english: Now as you may know, sound travels in waves, so if you have a speaker, a speaker actually does nothing else than taking the audio signal, transform it into a vibration, which is then transported through the air, is captured by our ear, and transformed into an audio signal again.
non_english: Kao što možda znate, zvuk putuje preko talasa, tako da ako imate zvučnik, zvučnik zapravo ne radi ništa drugo osim što uzima zvučni signal, pretvara ga u vibraciju koja se onda prenosi kroz vazduh, nju čuje naše uho, i onda se opet pretvara u zvučni signal.
