Tomas Chlebek I-iPhone yokuqala (phakathi kwezinye izinto) yayihlukile ngoba yayinojekhi womsindo ongu-3,5mm. Nakuba yayishumekwe ijule kancane edivayisini futhi ezimweni eziningi kwakudingeka kusetshenziswe i-adaptha, kwakusengenye yezingqalabutho zokulalela umculo ngomakhalekhukhwini. I-iPhone 7 ingena cishe ngakolunye uhlangothi. Kusho ukuthini lokho ngempela?
Isixhumi esimisiwe, esingu-6,35mm somsindo esiphumayo njengoba sisazi namuhla sisukela cishe ngo-1878. Izinguqulo zayo ezincane ezingu-2,5mm kanye no-3,5mm zaqala ukusetshenziswa kakhulu kumarediyo e-transistor ngeminyaka yawo-50 kanye nawo-60 futhi ujeke ongu-3,5 mm waqala ukubusa imakethe yomsindo ngemva kokufika kwe-Walkman ngo-1979.
Kusukela lapho, isibe ngesinye sezindinganiso zobuchwepheshe ezisetshenziswa kakhulu. Ikhona ekulungisweni okuningana, kodwa inguqulo ye-stereo enoxhumana nabo abathathu ivela kaningi. Ngaphezu kokuphumayo okubili, amasokhethi amamilimitha amathathu nesigamu nawo aqukethe okokufaka, sibonga lapho umbhobho ungaxhunywa khona (isb. I-EarPods enombhobho wezingcingo) futhi enikeza amandla kumadivayisi axhunyiwe. Kuyisimiso esilula kakhulu, okuyilapho futhi amandla aso nokwethembeka kulele khona. Nakuba uJack wayengesona isixhumi somsindo esisezingeni eliphezulu esitholakalayo lapho siphrofayilishwa, sisonke sibonakale sisebenza kakhulu, esisekhona nanamuhla.
Ukuhambisana kwejekhi akunakulinganiswa ngokweqile. Kodwa-ke, ukuba khona kwayo cishe kuyo yonke imikhiqizo yabathengi nengenakubalwa ephumayo yomsindo ayenzi umsebenzi ube lula kuphela kubakhiqizi bama-headphone, izipikha namakrofoni amancane. Empeleni, kungabhekwa njengohlobo lwento yentando yeningi emhlabeni wezobuchwepheshe, okungenani kumadivayisi eselula.
Ziningi iziqalo nezinkampani zobuchwepheshe ezincane ezenza zonke izinhlobo zezisekeli ezixhumeka kujekhi ongu-3,5mm. Kusukela kumfundi wamakhadi kazibuthe kuye kumathemometha namamitha enkundla kagesi ukuya kuma-oscilloscope nezikena ze-3D, wonke amathuluzi anjalo kungenzeka abengekho ukube ubungekho umkhiqizi otholakala kalula- noma indinganiso ezimele yesikhulumi. Okungashiwo ngakho, isibonelo, izintambo zokushaja, njll.
Ukubhekana nekusasa ngesibindi?
[su_youtube url=”https://youtu.be/65_PmYipnpk” wide=”640″]
Ngakho-ke i-Apple yanquma hhayi kuphela ukuya "esikhathini esizayo" ngokuya ngama-headphone, kodwa futhi namanye amadivaysi amaningi (ikusasa lawo lingase lingabi khona nhlobo). Esiteji, uPhil Schiller ngokuyinhloko wabiza lesi sinqumo ngokuthi yebo ngesibindi. Akungabazeki ukuthi wayebhekisele kulokho uSteve Jobs ake akusho ngeFlash: “Sizama ukwenzela abantu imikhiqizo emihle, futhi okungenani sinesibindi sokukholelwa kwethu ukuthi lokhu akuyona into eyenza umkhiqizo ube muhle, thina’ ngeke ngiyifake kuyo.
“Abanye abantu ngeke bakuthande futhi bazosithuka […] kodwa sizokuncela lokho futhi esikhundleni salokho sigxilise amandla ethu kulobo buchwepheshe esicabanga ukuthi buyakhula futhi buzofaneleka kumakhasimende ethu. Futhi niyazi ukuthini? Bayasikhokhela ukuze senze lezo zinqumo, senze imikhiqizo engcono kakhulu. Uma siphumelela bazowathenga, uma sehluleka ngeke bawathenge, konke kuzolunga.'
Kubonakala sengathi amagama afanayo ncamashi angashiwo othile (uSteve Jobs?) esimweni samanje. Nokho, njengoba ephikisana UJohn Gruber, I-Flash yayiyicala elihluke kakhulu kunejekhi engu-3,5mm. Akubangeli izinkinga, ngokuphambene nalokho. I-Flash bekuwubuchwepheshe obungathembekile obunezici ezimbi ngokuphawulekayo mayelana nokusetshenziswa kwamandla, ukusebenza nokuphepha.
UJack usephelelwe yisikhathi ngokwezobuchwepheshe, kodwa, okungenani emehlweni omphakathi, akanazo izimfanelo ezingezinhle eziqondile. Okuwukuphela kwento engagxekwa ngayo ukuthambekela kwayo ekulimaleni kwemishini okubangelwa ukwakheka kwayo, izinkinga ezingaba khona ngokudluliselwa kwesignali kumasokhethi amadala namajack, nomsindo ongemnandi ngezikhathi ezithile lapho uxhuma. Ngakho-ke isizathu sokushiya i-jack kufanele kube izinzuzo zezinye izindlela, kunokuba kube nokubi.
Ingabe kukhona okungcono esikhundleni sikajekhi ongu-3,5mm?
Ijekhi iyi-analog futhi ikwazi ukunikeza amandla amancane kuphela. Isignali edlula kusixhumi ngeke isakwazi ukushintshwa ngokuphawulekayo, futhi isilaleli sincike ku-hardware yomdlali ngekhwalithi yomsindo, ikakhulukazi i-amplifier ne-digital-to-analog converter (DAC). Isixhumi sedijithali esinjengombani sivumela la madivayisi ukuthi afakwe kabusha futhi anikeze okukhiphayo kwekhwalithi ephezulu. Kulokhu, yiqiniso, akudingekile ukulahla i-jack, kodwa ukuqedwa kwayo kushukumisela umenzi ukuthi athuthukise ubuchwepheshe obusha.
Isibonelo, u-Audeze usanda kwethula ama-headphone anakho kokubili i-amplifier nesiguquli esakhelwe kuzilawuli futhi akwazi ukunikeza umsindo ongcono kakhulu kunama-headphone afanayo ane-analog jack engu-3,5mm. Ikhwalithi ithuthukiswa ngokwengeziwe yikhono lokujwayela ama-amplifiers neziguquli ngqo kumamodeli athile e-headphone. Ngaphandle kwe-Audeza, amanye ama-brand asevele eqhamuke nama-headphones a-Lightning, ngakho-ke asikho isidingo sokukhathazeka ngokuthi ngeke kube khona okukhethwa kukho esikhathini esizayo.
Ngakolunye uhlangothi, ububi bokusebenzisa isixhumi sombani ukungahambisani kwaso, okuyinto evamile kuzixhumi ze-Apple. Ngakolunye uhlangothi, washintshela ezingeni elizayo le-USB-C le-MacBooks entsha (ekuthuthukisweni yena ngokwakhe abambe iqhaza), kodwa kuma-iPhones usashiya inguqulo yakhe, ayinikeza ilayisense futhi ngokuvamile eyenza ukuthuthukiswa kwamahhala kungenzeki.
Lokhu mhlawumbe inkinga enkulu ngesinqumo sika-Apple sokususa ijekhi engu-3,5mm - ayizange inikeze enye indlela eqinile ngokwanele. Mancane amathuba okuthi abanye abakhiqizi bashintshele ku-Lightning, ngakho-ke imakethe yomsindo izohlukana. Noma singabheka i-Bluetooth njengekusasa, kungenzeka ukuthi ibe kuma-smartphones asenayo kakade - amanye amadivaysi amaningi alalelwayo angayisebenzisa kuphela ukuxhuma ama-headphone, ngakho-ke kungase kungafaneleki ukusetshenziswa - futhi futhi, ukuhambisana kwehla. . Mayelana nalokhu, kubonakala sengathi isimo emakethe yama-headphone sizobuyela ngendlela esasiyiyo ngaphambi kokufika kwama-smartphones esimanje.
Futhi, uma kuziwa ekuxhumaniseni ama-headphone angenantambo kuma-smartphones, i-Bluetooth ayikalungi ngokwanele ukuvala ikhebula. Izinguqulo zakamuva zalobu buchwepheshe akufanele zisaba nezinkinga ngekhwalithi yomsindo, kodwa azisondeli neze ezilalelini ezanelisayo zamafomethi angalahleki. Nokho, kufanele ikwazi ukunikeza umsindo owanelisayo okungenani wefomethi ye-MP3 ene-bitrate engu-256KB/s.
Amahedfoni e-Bluetooth nawo azohambisana kakhulu emhlabeni wama-smartphone, kodwa izinkinga zokuxhuma zizovela kwenye indawo. Njengoba i-Bluetooth isebenza ngefrikhwensi efanayo nobunye ubuchwepheshe obuningi (futhi kuvame ukuba nezisetshenziswa eziningi ezixhunywe nge-Bluetooth ezindaweni eziseduze), ukwehla kwesignali kungenzeka, futhi ezimeni ezimbi kakhulu, ukulahleka kwesignali kanye nesidingo sokubhanqa kabusha.
Apple u ama-AirPods amasha uthembisa ukwethembeka kulokhu, kodwa kuzoba nzima ukunqoba eminye yemikhawulo yezobuchwepheshe ye-Bluetooth. Ngokuphambene nalokho, iphuzu eliqine kakhulu lama-AirPods namandla amakhulu kakhulu wama-headphone angenantambo yizinzwa ezingakhelwa kuzo. Ama-Accelerometer awakwazi ukusetshenziselwa kuphela ukukhombisa ukuthi i-handset ikhishiwe endlebeni, kodwa futhi angakala izinyathelo, ukushaya kwenhliziyo, njll. I-hands-free ye-Bluetooth eyayikade ingabukeki futhi engathembekile manje ingase ithathelwe indawo ngama-headphone ahlakaniphe kakhulu, afanayo. ku-Apple Watch, yenze isebenze kahle futhi isebenze kamnandi nobuchwepheshe.
Ngakho-ke i-headphone jack engu-3,5mm isiphelelwe yisikhathi ngempela, futhi izimpikiswano ze-Apple zokuthi ukususa i-jack yayo ku-iPhone kuzovulela indawo ezinye izinzwa (ikakhulukazi i-Taptic Engine ngenxa yenkinobho entsha Yasekhaya) futhi ivumele ukumelana kwamanzi okuthembekile. efanele. Kukhona nobuchwepheshe obunamandla okububuyisela ngempumelelo futhi bulethe izinzuzo ezengeziwe. Kodwa ngayinye yazo inezinkinga zayo, kungakhathaliseki ukuthi akunakwenzeka ukulalela nokushaja ngesikhathi esifanayo, noma ukulahlekelwa ama-headphone angenantambo. Ukususwa kwejekhi engu-3,5mm kuma-iPhones amasha kubonakala kungenye yalezo zinyathelo ze-Apple ezibheke phambili ngempela, kodwa azenziwanga ngobuchule.
Intuthuko eyengeziwe kuphela, engeke ize ngobusuku obubodwa, ezokhombisa ukuthi ngabe i-Apple ibiqinisile futhi. Kodwa-ke, ngeke neze sibone ukuthi kufanele iqale i-avalanche futhi ijekhi engu-3,5mm kufanele ilungiselele ukuhlehla kodumo. Igxile kakhulu emashumini ezigidi zemikhiqizo emhlabeni jikelele ngalokho.
Isihloko esihle. Ngokwami, angifuni ukuyeka ama-headphones anentambo ngenxa yokunethezeka. Abafuni ukungikhokhisa ngaso sonke isikhathi ukuthi nginake lapho bekhona futhi ngibakhokhele kakhulu. Ngakolunye uhlangothi, ikusasa eliqhakazile, okungenani ngokuqondene nabasebenzisi abajwayelekile. Ukuze i-audiophile ifune ikhwalithi ephezulu kakhulu, cishe kuyoba kuhle kakhulu ukuhamba nama-headphones anciphisa noma akhanyayo, okuyiqiniso, angaxhumi kwenye indawo :/ i.e. Mac njll.
Ngiyabonga ku-Back to School, ngithole ama-headphone esizukulwane se-Beats 2. Kufanele ngisho ukuthi ibhethri ihlala izinsuku ezimbalwa futhi ngiyisebenzisa amahora ambalwa ngosuku. Impela kuzofika amabhithi amasha futhi ngubani owaziyo ukuthi umsindo we-3d wendawo uzoletha ini, Ukukhanselwa komsindo okusebenzayo? Lokho kuzoba ukuqhuma, akungikhathazi ukuthi umuntu unama-headphone amadala futhi angathanda ukuwasebenzisa ku-iPhone entsha. Kimina kubonakala sengathi othile ufuna ukubeka i-DVD noma i-VHS ku-Bluray.
Uma othile enama-headphone enziwe ngokwezifiso ane-jack engu-3,5 mm yezinkulungwane ezingamashumi amathathu, ngicabanga ukuthi ukufaniswa okunjalo kuzobonakala kungavamile kuye :-) Kuyiqiniso ukuthi umuntu onjalo cishe usebenzisa isiguquli sangaphandle kanye ne-amplifier, exhunywe kuyo. iphone vele umbani, kodwa uma engayiboni, uphelelwe inhlanhla.
Ngakho-ke umuntu onaleyo DVD ngeke neze abe nayo eyodwa. Ngiyazi abaqoqi abaningi umtapo wabo we-DVD ubiza ngaphezu kwezinkulungwane ezingama-30. Ngamafuphi, abantu abanjalo bakhona futhi bazoba khona, nokho-ke, idlanzana labo kufanele lilindele ukuthi lizoba sesimweni esibucayi uma liqhathaniswa neningi, isibonelo ngokuthi ichweba elifunwayo liyomane lingekho. Imakethe izophinde ibe nabadlali namadivayisi aqondiswe kubo ngqo.
kungani kufanele amamatheke lapho i-adaptha ye-iphone 7 ilungile ebhokisini ;-)
Ukukhokhela i-wireless kunezingibe zakho uma usutholile mayelana nekhwalithi yayo kanye nentengo. Ujeke ongu-3,5 uyindinganiso hhayi ngoba ugqamile, uyindinganiso ngoba uletha isilinganiso esihle kakhulu samanani/sokusebenza. Kodwa-ke, i-Apple ibheke ngokusobala uhlobo olulodwa lwabantu - labo abanemali eyanele kodwa ikhwalithi iyigama nje kubo - banendaba kakhulu nomkhiqizo.
Lokhu kungenzeka kumahedfoni angenantambo, kodwa ngicabanga/ngethemba ukuthi isimo si/sizohluka ngombani.
Ngiyangabaza ukuthi azoke abe nama-headphones ombani ongawathenga ngo-150 CZK. Hhayi ukuthi ngingumlandeli walabo, kodwa ngesikhathi bengithumelela i-Klipsch X4i, ngithenge eyodwa ngemali elinganiselwa ku-200 CZK ngesikhathi sesimangalo. Kepha i-BT eshibhe kakhulu izoba ngama-800,- futhi angilokothi ngiqagele ngombani ngoba wonke umkhiqizi kusazodingeka athenge ilayisense kwa-Apple. Futhi ngicabanga ukuthi lokho kungenye yezisusa zabo. Babi kabi.
Ikakhulukazi, ngicabanga ukuthi i-jack yanyamalala ku-iPhone ngoba yayifuna imakethe yeselula futhi ayikwazi ukuhambisa noma kuphi. Ngakho-ke i-apula kwadingeka liphinde lishaye udonga ngekhanda futhi liqhamuke "nokuqamba okusha"
Nge-SIMKAMA, abantu nabo bathuka.
Angiqondi ukuthi kungani bengabaniki abantu ukukhetha. Babengase bashiye ujeke futhi balethe ithuba lokuxhuma ama-headphone ngombani, kodwa mhlawumbe wonke umuntu ubengakuzonda lokho :D
Sicela ulungise iphutha mayelana nonyaka ijack yomsindo eyethulwe ngayo...ngicabanga ukuthi yayingekho ngo-1878. ;)
Ngokolwazi olutholakalayo, ujeke omkhulu, oyikota-intshi empeleni wasetshenziswa okokuqala ngqa ngo-1878.
Kuyiqiniso, ekuqaleni yayisungulelwe inkambu yokushintsha yokushintshana ngocingo, lezo ezisetshenziswa ngokuqinile, lapho imigqa engapheli yabesifazane yayihlala futhi ixhume ikholi ngayinye ngesandla :-)
Ukhohlwe futhi izinto ezimbili ezibalulekile:
1, i-DRM - okukhiphayo kwedijithali kulawulwa kangcono kakhulu futhi i-Apple ingalayisensa umbani kahle, kanti nge-analog ungaxhuma noma yini oyifunayo. Inkinga nge-bluetooth ukuthi kukhona njalo amazinga amasha futhi ikhula ngokushesha. Ungathenga ama-headphone wekhwalithi nabashayeli abahle ezinkulungwaneni ezimbalwa, kodwa ngemva kweminyaka embalwa uzothola ukuthi kukhona okungcono kakhulu. Uma unokuphuma kwe-analog kwekhwalithi ephezulu, awakho ama-headphone ngeke aguge kangako.
2. Inzuzo ye-jack uma iqhathaniswa nombani, isibonelo, ukuthi i-omnidirectional. U-Apple waqhosha ngokuthi umbani wawune-bi-directional ngenkathi yethulwa, okwakuyinto enhle kakhulu uma iqhathaniswa ne-microUSB noma isixhumi esidala, kodwa i-jack empeleni ingcono nakakhulu kulokhu.
Sekukonke, kubonakala kimi ukuthi ukususwa kwe-jack kungaletha izinzuzo ezithile, kepha ngicabanga ukuthi zonke izinto zingafakwa ngandlela thile ku-iPhone noma ngabe i-jack igcinwe. Ngicabanga ukuthi umzamo we-Apple kwesinye isixazululo sokuphathelene uphumelele lapha, nokuthi akuyona into umsebenzisi okufanele ajabule ngayo.
Ngasuka ku-Windows ngaya ku-OS X ikakhulukazi ngenxa ye-Logic Pro X, futhi kubonakala kimi ukuthi abakhiqizi abaningi (impela e-US) nabo basebenzisa ama-Mac. Kungakho ngingawuqondi umqondo wokukhipha ujeke ongu-3,5 mm nhlobo. Noma mhlawumbe uke wabona umuntu ongenazintambo esitudiyo. ama-headphone?
Isihloko esihle Ngiyabonga. Kufanele ngincome kakhulu namazwana. Madoda, isiko eliphezulu lokuxoxa. Ngiyabonga
Uma abantu benikezwa ithuba lokuzikhethela, AKUKHO LUTHO NGEKE KUYA NOMA KUPHI: "Uma ngibuza abantu ukuthi bafunani, bangafuna ihhashi elisheshayo H. Ford! Kwesinye isikhathi kudinga isibindi namandla futhi akuphumeleli ngaso sonke isikhathi. Khona-ke isibindi namandla kudingeka ngokuphindwe kabili. I-Apple ingumkhiqizo oqinile, inesithombe esikhulu kangaka, ukusekelwa kwamakhasimende futhi imikhiqizo yayo isezingeni lokuthi ingakwazi ukukhokhela imizamo enjalo. Ayikho enye inkampani engiyaziyo engasingatha lokhu. Kuhlale kulindelwe ukuthi i-Apple izoza nani, bese umhlaba uphikisana isikhathi eside, futhi okwamanje abanye bakopisha buthule. Kwesinye isikhathi ngibuye nginikine ikhanda, kodwa ngiyabamukela futhi ngiyabethemba.
Ngokwami, ingicasula kakhulu ijekhi yomsindo engu-3,5 yakudala, etholakala kuma-iPhone 6s, ngokwesibonelo, ngibe nama-6s izinyanga ezi-5, ngisebenzisa ama-headphone amancane kakhulu futhi umzimba we-iPhone uyaklwebheka eduze kwejack. Lokhu akwenzeki kubantu abane-7, i-Lightning port ivikelwe nxazonke uhlobo oluthile lwensimbi noma okuthile. :-(
