Imbali emfutshane yeRadio yeMoto

Imbali yerediyo yemoto isukela ngeminyaka yoo-1920s kunye nee-30s, kodwa iinguqu zayo eziqhubekayo ziye zabumba inkcubeko yepop, ishishini lomculo, kunye nokhuseleko ezindleleni kude kube namhlanje. Iphinde yadlula kwiinkqubela ezininzi zetekhnoloji, ezidlale indima ebalulekileyo kulo lonke uphuhliso lwayo.

Irediyo yemoto ngumthombo othembekileyo nolungeleyo wokuzonwabisa, kodwa impembelelo yayo inkulu kunokusetyenziswa kwayo ekuqhubeni yonke imihla. Nantsi inkcazo emfutshane yembali kanomathotholo wemoto kunye neendlela eziphembelele ngayo uluntu.

Imbali yerediyo yemoto

Nokuba kunyuswa ii-audiobooks, ii-podcasts, kunye nee-apps zomculo, abathengi basathembela kwirediyo yemoto ukubasonwabisa njengoko behamba. Uphando lwe-Edison iphawula ukuba i-73% yabantu baseMelika basasebenzisa unomathotholo wemoto njengomthombo wabo wokulalela. Ngapha koko, abathengi abanakwenzeka ukuba baqeshise okanye bathenge imoto ukuba akukho tuner yerediyo, ngokutsho Uphando lwe-2021 kwakhona ngu-Edison Research. Malunga ne-25% ye Abaphulaphuli beSpotify bacula kakhulu ngelixa bekwimoto yabo.

Oonomathotholo bemoto bokuqala bazalwa ngeminyaka yoo-1920 ngetekhnoloji yetyhubhu yevacuum, eluhlobo lobuchwepheshe be-elektroniki. Esi sixhobo sasebenzisa isitshixo setyhubhu yeglasi ukulawula ukuhamba kombane. Ngelixa bulky, zibiza, kwaye ayisebenzi kakhulu, le teknoloji bekunjalo esetyenziswa kumabonwakude, unomathotholo, kunye nezixhobo zekhompyuter.

Irediyo yokuqala yorhwebo ye-amplitude modulation (AM) yasungulwa ngo-1930 nguJoseph noPaul Galvin beGalvin Manufacturing Corporation (ngoku ebizwa ngokuba yiGalvin Manufacturing Corporation). Motorola). I-Motorola Model 5T71 yathengiswa njengekiti kubanini beemoto ukuze bayifake. I-Chevrolet yaqala ukubonelela ngeerediyo ezifakwe kwifektri ngo-1930.

Ngo-1955, inkampani iBlaupunkt yazisa irediyo yokuqala yokumodareyitha (FM) ngokukodwa kwiimoto. Imodeli yabo ye-Autosuper 5 yayinomgangatho ongcono wesandi kunye noluhlu olubanzi lwamatshaneli kunerediyo ze-AM. Iminyaka yoo-1960 yeza nezidlali zeteyiphu ezineengoma ezisibhozo, ngelixa iikhasethi zikanomathotholo zemoto zaziswa ngeminyaka yoo-1970. Kwi-dash abadlali be-compact disc (CD). yaqaliswa ngo-1985, ivumela abaqhubi ukuba balungise amava abo okuqhuba.

Yayingekokuhambela phambili kwetekhnoloji kuphela, kodwa abavelisi beemoto kunye neenkampani zokuzonwabisa zedijithali (ezinje Alpine kwaye U vu lindlela) bebesebenzisana ukubonelela ngeenkqubo zestereo zeprimiyamu.

Iintlobo zeerediyo zeemoto

fanekiso

I-analog lolona hlobo ludala lukanomathotholo, kwaye igama elithi analog libhekisa kwinkqubo yemiqondiso ye-elektroniki esebenzisa imiqondiso eyahlukeneyo ukuhambisa amaza erediyo. Imiqondiso yerediyo ye-Analog iqhutywa kusetyenziswa i-AM okanye i-FM yomphathiswa ukutolika ulwazi oluvakalayo. Ezi nkqubo ziqhelene nokungashukumi, ukuphazamiseka, kunye nomgangatho ophantsi wesandi. Namhlanje, unokufumana iirediyo ze-analog kwiindawo ezisemaphandleni okanye kwizithuthi ezindala.

Digital

Inguqu yedijithali koonomathotholo beemoto yaqala ngeminyaka yoo-1980 kunye noo-1990, ubukhulu becala ithatha indawo yeenkqubo ze-analog. Iishuni zeDijithali zibonelela ngomgangatho wesandi ococekileyo ngakumbi kunye nokwamkelwa okungcono, kunye nokusetyenzwa komqondiso wedijithali (DSP) Yamkela iimpawu eziphambili ezinje ngokunciphisa ingxolo kunye nokulinganisa.

Ezi nkqubo zisebenzisa imiqondiso ecacileyo ukuguqula imiqondiso yesandi kwifomati yedijithali, emva koko ulwazi lugqithiselwe kwidatha yedijithali. Loo datha ihlanjululwe ngummkeli werediyo usebenzisa i-hardware ekhethekileyo kunye nesoftware, ekhokelela kwisandi esikumgangatho ophezulu. Ngokungafaniyo ne-analog, unomathotholo wedijithali unokuphazamiseka okuncinci kunye ne-static.

satellite

Irediyo yesathelayithi luhlobo lwerediyo yedijithali. Kolu hlobo, imiqondiso ifunyanwa kwiisathelayithi ezikwi-orbit, evumela uluhlu olubanzi lwamajelo. Ukufikelela kwirediyo yesathelayithi, abaphulaphuli basebenzisa isathelayithi yomamkeli werediyo edla ngokuvulwa ngenkonzo yorhumo.

Okwangoku, kukho iinkampani ezininzi zokurhuma ngesathelayithi ezifana neSiriusXM kunye neHeartMedia. Ukongeza kumxholo okhethekileyo kunye neetshaneli ezinokwenziwa ngokwezifiso, le nkonzo yerediyo inomgangatho ophezulu wesandi kunye nobuninzi bamajelo enkqubo.

Itekhnoloji ye-Smart

Olona hlobo lutsha lonomathotholo lwemoto lubandakanya itekhnoloji ehlakaniphile enikezela ngendlela engaphezulu nje kokumamela umculo. Oonomathotholo banamhlanje bemoto baquka itekhnoloji ehlakaniphile “i-infotainment” evumela abaqhubi ukuba baqhagamshele ii-smartphones zabo kwisithuthi sabo Bluetooth uqhagamshelwano okanye izibuko ze-USB.

Oonomathotholo bobuchwepheshe be-Smart baqhagamshela kwi-Intanethi, babonisa iimephu kunye nokukhangela, kwaye bafikelele kwiinkonzo zokusasaza umculo. Abanye abavelisi beemoto bade babe nezikrini ezidibeneyo zokuchukumisa.

Impembelelo kuluntu

Qhuba-kwiithiyetha

Ekuqaleni kwenkulungwane yama-20, oonomathotholo beenqwelo-mafutha babesetyenziselwa ukusasaza isandi sefilimu ngenkqubo yenqwelo-mafutha. Ngokutshintshela kwisitishi esithile sikanomathotholo, iithiyetha zokuqhuba zivumela abaqhubi babukele imuvi kwaye bayive njengendlela ephathwayo nekhululekileyo yokuzonwabisa.

Ukukhuthazwa koMculo

Irediyo yemoto kudala iyindawo yokukhupha iilebhile zokurekhoda ukukhuthaza amagcisa kunye nomculo wabo. Iimvumi zixhomekeke kwizikhululo zikanomathotholo ukuba zincede ukukhulisa ukwazisa nokurekhoda ukuthengisa. Nangona iinkonzo zokusasaza kwi-intanethi ziye zathatha indawo yerediyo yemveli, unomathotholo useyeyona ndlela ibalulekileyo yamagcisa asekhaya nazimeleyo ukuba afumane abalandeli.

Iifomathi zikanomathotholo

Kwiminyaka yoo-1970 kunye no-1980, izikhululo zikanomathotholo zaqala ukubonelela ngeendlela ezininzi zomculo ukuze zibonelele abaphulaphuli abahlukeneyo. Kwakukho intlaninge yerap, iR&B, rock and roll, country, jazz, kunye nezikhululo zikanomathotholo. Le yantlukwano ikhokhelele kubantu berediyo kunye nee-disc jockeys (ii-DJs).

Ukhuseleko ezindleleni

Ukususela ekuvelisweni kwerediyo yemoto, ezi zixhobo ziye zadlala indima ebalulekileyo kwimpilo yoluntu. Amagosa olawulo olungxamisekileyo asebenzisa unomathotholo wemoto ukusasaza iintlekele zendalo, ii-odolo zokufuduka, kunye nezilumkiso ze-Amber.

Ukususela ngeminyaka yee-1960 kunye neyee-1970, izikhululo zikamabonwakude zasekuhlaleni zaqalisa ukunika ingxelo ngeengozi zendlela kunye neengxelo zezithuthi eziqhelekileyo. Kweli xesha lanamhlanje lokuqhuba okuphazamisekileyo, kukho imithetho kunye namaphulo oluntu okukhuthaza abaqhubi ukuba bahlale bephaphile kwaye beqaphela ngelixa beqhuba. Uninzi lwabavelisi beemoto ngoku lubandakanya iimpawu zokhuseleko oluphezulu ezifana nolawulo lwelizwi, isikrini esichukumisayo, kunye neenkqubo ezilungisa ngokuzenzekelayo ivolumu yerediyo ngokusekwe kwisantya.

isiphelo

Irediyo yemoto inikezela ngaphezu komculo nje. Ukuvela kwayo kutshintshe amava okuqhuba ukusuka kuphuculo lokhuseleko ezindleleni ukuya ekukhetheni ifomathi yerediyo. Ngokufunda imbali yerediyo yemoto, imakethi inokubona ukuba icandelo lihambele phambili kangakanani kwaye lijonge phambili kwinto enokuba yintoni ikamva lerediyo yemoto. Njengoko itekhnoloji ikhula, kuya kuba ngumdla ukubona indlela imoto yomsakazo iyaqhubeka ukuziqhelanisa kunye nokutshintsha kunye namaxesha kwiminyaka ezayo.
