Siyazi ukuba indawo evelisa isandi ye #sithethi sisithethi, kodwa kutheni usebenzisa #isithethi endaweni yokumamela ngqo #isithethi? Injongo ye-#speaker kukuthintela umqondiso wamaza wesandi ukusuka ngaphambili nangasemva kwe #speaker diaphragm. I-loop yenziwe, ukwenzela ukuba kuphela izandi eziphezulu ze-frequency kunye ne-intermediate-frequency kunye ne-wavelength encinci inokuhanjiswa, kunye nezinye iimpawu zesandi zibekwe phezulu kwaye zicinywe. Imodeli ebonakalayo ye #sithethi kukuvula umngxuma kwibhaffle engqongqo engapheliyo ukufakela #isithethi, ukuze kuqinisekiswe ukuba uphawu lwesandi ngaphambili nangasemva kwe #sithethi aluyi kwenza iluphu, okukhokelela kwisandi. iluphu yamaza. Nangona kunjalo, ekusetyenzisweni okwenyani, i#speaker asinakwenziwa singenasiphelo. Ngoko ke, abantu basebenzisa i-baffle emva kwe-#speaker ukwenza indawo evaliweyo ukuqinisekisa ukuhanjiswa kwangaphambili kwamaza esandi.
