Isithethi saziwa ngokuqhelekileyo ngokuthi "uphondo", luhlobo lwe-electroacoustic transducer kwisixhobo somsindo, ukubeka ngokulula, kukubeka i-bass kunye nesandisi-lizwi kwibhokisi.Kodwa njengoko uphuhliso lwesayensi kunye nobuchwepheshe, uyilo lwesandi ngenxa yokuphuculwa kwezinto eziphathekayo, umgangatho wecandelo elifana nesandisi-lizwi kunye nesithethi selizwi eliphezulu uphuculwe ngokucacileyo, ibhokisi yesithethi yongeze umsebenzi omtsha, ibe nefuthe elikhulu kwaye lingcono.
Kwiminyaka yakutshanje, imfuno yeenkqubo zenethiwekhi ye-audio iye yanda, kwaye ngohlaziyo lwangaphakathi lwamacandelo e-elektroniki, abaninzi ababoneleli benkqubo ye-audio baye badibanisa iteknoloji ye-audio ye-audio kwisixhobo somsindo, okwenza izithethi zihlakaniphe.
Ukongeza kwiinkqubo zothungelwano lwe-audio, uninzi lwe-stereo ngoku luqulathe amanye amacandelo e-elektroniki kunye ne-digital signal processors, eqinisekisa ukuba isithethi ngasinye sinokulungiswa ukuze sinikeze isandi esilungileyo sommandla ogqunyiweyo kunye nesiza sonke.Ukulawulwa kwe-Beam, umzekelo, isebenzisa iteknoloji yokulawula idijithali ukulawula ukuhanjiswa kwesandi, ukuvumela umyili ukuba adibanise iziphumo zokuqhuba ezininzi (ngokuqhelekileyo kwisandi sekholomu) ukuqinisekisa ukuba isandi sihanjiswa kuphela apho umyili ufuna ukuba afike khona.Obu buchwephesha buzisa inzuzo enkulu yeacoustic kwiindawo ezinzima zokubuyela umva ezifana nezikhululo zeenqwelomoya kunye neecawe ngokususa imithombo yesandi ukusuka kwindawo ebonisiweyo.
Malunga noyilo lwangaphandle
Enye yeengongoma eziphambili zoyilo lwesandi yindlela yokulungelelanisa isandi kunye noyilo lwangaphakathi okanye isitayela sendawo yokusebenza, ngaphandle kokwenza umonakalo kwizinto zokuqala zoyilo.Kwiminyaka yakutshanje, ubugcisa bezinto zokuvelisa isandi ziye zaphuculwa, kwaye imagnethi enkulu kunye nenzima yeferrite iye yathatyathelwa indawo yintsimbi encinci kunye nekhaphukhaphu enqabileyo yomhlaba, isenza uyilo lwemveliso ngakumbi kwaye icwecwe kwaye imigca ibe mihle ngakumbi.Ezi zithethi azisayi kuphinda zingqubane noyilo lwangaphakathi kwaye zisakwazi ukubonelela ngenqanaba loxinzelelo lwesandi kunye nokucaca okufunekayo kuyilo lwe-acoustic.
