Ukuveliswa kwerekhophi yokurekhoda

Ukuba sicinga ukuveliswa kwerekhoda, oko kukufanelekile ukuxelela imvelaphi yento eyadalwa ngaphambi kwayo. Kucatshangelwa ukuba ukuveliswa kwezinto zokuqala, ezirekhodiweyo isandi, esibizwa ngegronograph, siyimfanelo kaThomas Edisson. Nangona kunjalo, ngokwenene, imbono yesigramafoni ngokupheleleyo ingqondo yeCharles Crewe - imbongi yesiFrentshi kunye nososayensi. Ngowe-1977, wangenisa iphepha kwi-Academy of Sciences yaseFransi, echazwe ngokucacileyo yonke into echaphazelekayo ngcamango. Eli phepha ligcinwe kweli liziko. Kwaye sele sele ngo-1878 le ngcamango yayinelungelo lobunikazi kwaye laphunyezwa nguEdison. Ngo-1886, uMnu. Chichister Bell kunye noCharles Sumner Tanner baseUnited States baqalisa ukuveliswa kwegramafoni kunye ne-winding kunye ne-cylinder eboshwe nge-wax. Ngowe-1887 u-Emil Berliner eJamani wayenelungelo lobunikazi ngcamango ye-modern turntable, apho kwakusetyenziswa iiplati ezicwecwe. I ngcamango iyafumaneka ngowe-1896.

Kulukhuni ukukholelwa, kodwa ukuveliswa kwerekhoda yeelayi kuwela ngexesha elifanayo njengoko kuqaliswe i-cinema. Kwabonakala ngexesha elifanayo njengemoto yokuqala. Umgaqo wokusebenza kwee-tape zokurekhoda zanamhlanje kwanyanzeliswa nguWoldemar Poulsen, owayengumqeshwa kwi-phone exchange in Copenhagen. Enye yeimbopheleleko zakhe ezithe ngqo kukuqinisekisa ukusetyenziswa ngokuqhelekileyo kwezixhobo kwisikhululo. Kwaye akukucaci ukuba ngaba izixhobo ziphezulu kakhulu okanye wayengumcebisi ontle, kodwa wayenexesha elininzi lokukhululeka. Wanikezela ngeentlobo ezahlukeneyo zokuvavanya ngamagnet, ii-coil, iingcingo kunye nezinye iinkcukacha. Inzala yakhe kunye nesifiso saye savuzwa ngokufumanisa ukuba kumnxeba omncinci wensimbi, kunokwenzeka ukuba ugqibe imimandla eyahlukileyo ngeendlela ezahlukeneyo. Ukuba ngokukhawuleza ukujikeleza ngekhamera ye-electromagnetic, unokuva isandi. Yile ndlela ukuveliswa kwereyipi eyayiqala ngayo. Waqala ukuhlakulela ingcamango yakhe ngakumbi, waza wada waya kwisigqibo sokuthi ululabheka ucingo phambi kwekhrofoni ngexesha elifanayo njengoko uthethayo, ungabhala kulolu qhawulo ilizwi lomntu okanye esinye isandi esiza kuthathwa yi-microphone ngexesha lokurekhoda . Le ngcamango yaqala ukuba iyathemba kakhulu kuba irekhodi lingasuswa, kwaye enye entsha ibhalwe phantsi kwintambo. Ukwenza oku, ufuna kuphela ukuvuselela intambo.

Ngomnyaka we-1898, umgcini-zimpawu wayesele ekhawuleza ukuba enze i-patent yakhe ifowuni, ebizwa ngokuba yi-telegraph, kwaye unyaka kamva wayelunikwe i-Grand Prix kwi-World Exhibition ye-Paris. Emva kwexesha elifutshane kakhulu, ukuveliswa kwaba nelungelo lobunikazi kwamanye amazwe, kwaye ngowe-1903 iNkampani ye-American Telegraph yayisele isisungulwe, eyayiyiphumelele ukuveliswa kwama-dictaphones. Ukuqulunqwa kwerekhope yee-tape kuye kwandipha umdla kuluntu. Nangona kunjalo, ukungahleleki kwezi zixhobo kwakucatshangelwa ukuba yinkxalabo yabo, kuba amateyiphi ayebhalwa kuyo ayenkulu kakhulu, kwaye umgangatho ozwakalayo wawuhluke kakhulu kwiigramafoni kunye negramophones. Oku kuchaza ubukho obufutshane benkampani. Nangona kunjalo, kwiminyaka eyi-10 kuphela kamva, xa izikhulu ezinamandla ngakumbi zaziswa kwihlabathi, iziphene eziphambili ze-tape recorders zapheliswa, kwaye umkhosi waba ngowokuqala ukuxabisa amandla amasha kwezixhobo ezinjalo. Kwiminyaka engama-20, iinqanawa zaseMerika zasebenzisa izixhobo ezitsha zokufumana ngokukhawuleza nokudluliselwa kwemilayezo ye-radiotelephone. Emva koko, ii-record recorder zaqala ukuvela eYurophu.

Isinyathelo esilandelayo kwakusungulwe i-tape magnetic, yintoni eyenza sikwazi ukudala ii- reel tape recorders. Ezi zixhobo zazinomdla kuluntu jikelele kuphela kwimimandla. Oku kubangelwa ukuba i-cassette ye-tape irekhoda sele ibonakala. Emva koko, baqala umkhosi wokunqoba kwiplanethi.
