Vidio sam ovo već.. skroz je kul.. pogledajte ak niste, isplati se. Samo pojačajte zvučnike, slabo se čuje *wink Wink
Neam pojma kak to rade, u svakom slučaju ima neke veze za zvučnim valovima ne...

Nisam siguran od kojeg je materijala ploča, ali je zvučnik definitivno ispod. Titranje iz zraka prenosi se na ploču na kojoj se pijesak skuplja na čvorovima titraja -- što je frekvencija viša, čvorovi su bliže i patterni kompliciraniji.

Važno je otkriti koji materijal najbolje titra, nakon čega taj pokus lako napraviš doma. Ploča definitivno treba biti što tanja.

Čista frekvencija se može proizvesti sa mnogo programa na kompjuteru

tako nešto sam i mislio da je, ploča na zvučniku...
a što se tiče izvora signala, znam da se može koristiti kompjuter, ali sam mislio to spojit na generator signala, pa s njime fino podešavati...ah, tehnička škola Rolling Eyes
