Adam Kos Ama-MacBook Pros amasha angu-14 no-16-inch ane-headphone jack ethuthukisiwe i-Apple ethi izokwamukela ama-headphone aphansi futhi aphezulu ngaphandle kwama-amplifiers angaphandle. Le nkampani ikwenza kucace ukuthi lena imishini yobuchwepheshe ngempela yazo zonke izimboni, okuhlanganisa onjiniyela bomsindo nalabo abaqamba umculo ku-MacBook Pro. Kodwa kuzokwenzekani ngalesi sixhumi sikajekhi esingu-3,5 mm?
I-Apple ikhishwe emakhasini ayo okusekela idokhumenti entsha, lapho echaza khona kahle izinzuzo zesixhumi sikajeke esingu-3,5 mm ku-MacBooks Pro entsha. Ithi izinto ezintsha zifakwe ukutholwa komthwalo we-DC kanye nokuphuma kwamandla kagesi okuguquguqukayo. Ngakho-ke idivayisi ingakwazi ukubona ukuthintana kwedivayisi exhunyiwe futhi ilungise ukuphuma kwayo kuma-headphone aphansi naphezulu kanye namadivayisi omsindo weleveli.
Kungaba njalo okuthakaselayo
U-Vratislav Holub Uma uxhuma ama-headphone ane-impedance engaphansi kuka-150 ohms, i-headphone jack izohlinzeka ngokufika ku-1,25V RMS. Kuma-headphone ane-impedance ye-150 kuya ku-1 kOhm, i-headphone jack inikeza i-3V RMS. Futhi lokhu kungaqeda isidingo se-headphone amplifier yangaphandle. Ngokutholwa kwe-impedance, okukhipha amandla kagesi okuguquguqukayo kanye nesiguquli esakhelwe ngaphakathi sedijithali-kuya-analogi esisekela izilinganiso zesampula ezifika ku-96kHz, ungakwazi ukujabulela ukwethembeka okuphezulu, umsindo onokucaca okugcwele ngokuqondile usuka kujekhi yeheadphone. Futhi mhlawumbe kuyamangaza.
Umlando ongadumile wesixhumi sikajack esingu-3,5mm
Kwakungu-2016 futhi i-Apple yasusa isixhumi se-jack engu-7mm ku-iPhone 7/3,5 Plus. Impela, usipakishele isinciphisi, kodwa kwase kuyisibonakaliso esicacile sokuthi kufanele siqale ukuvalelisa kulesi sixhumi. Uma ucabangela isimo ngama-Mac akhe nesixhumi se-USB-C, kubonakale kunengqondo. Kodwa ekugcineni, kwakungemnyama kangako, ngoba sisenayo kumakhompyutha we-Mac namuhla. Kodwa-ke, mayelana nomsindo "weselula", i-Apple yayizama ngokusobala ukuqondisa kabusha abasebenzisi bayo ukuthi batshale imali kuma-AirPods ayo. Futhi waphumelela kulokho.
Igalari yezithombe
I-12" MacBook ibiqukethe i-USB-C eyodwa kuphela nesixhumi sikajekhi esisodwa esingu-3,5 mm futhi akukho okunye. I-MacBook Pros yayinama-USB-C amabili noma amane, kodwa yayisafakwe i-headphone jack. IMacBook Air yamanje ene-M1 chip nayo inayo. Emkhakheni wamakhompyutha, i-Apple ibambelele kuyo izinyo nezipikili. Kepha kungenzeka ukuthi ukube bekungekho ubhubhane lwe-coronavirus lapha, i-Air ibingeke ibe nayo.
IMacBook Air M1
Ebangeni lobungcweti, ukuba khona kwayo kunengqondo futhi ngeke kube ukuhlakanipha ukuyisusa lapha. Noma yikuphi ukudluliswa okungenantambo kuyalahleka, futhi awufuni lokho kwenzeke kumkhakha wochwepheshe. Kodwa ngedivayisi evamile, isidingo saso akudingekile. Ukube besiphila ezikhathini ezijwayelekile futhi ukuxhumana phakathi kwenzeka njengoba kwenzeka ngaphambi kwalolu bhubhane, mhlawumbe iMacBook Air ibingeke isaba nalesi sixhumi, njengoba nje neMacBook Pro ibingeke ibe nokunqanyulwa. Sisaphila esikhathini lapho ukuxhumana okukude kubalulekile.
Kungaba njalo okuthakaselayo
Ukuyekethisa okuthile kuphinde kwabonwa ku-24" iMac, elinganiselwe kakhulu ekujuleni kwayo, futhi i-Apple ngakho-ke ibeke lesi sixhumi ohlangothini lwekhompuyutha yayo yonke-in-one. Ngakho-ke kuyadingeka ukuhlukanisa phakathi kwale mihlaba emibili. Kweyeselula, ungakhuluma nelinye iqembu ngokuqondile, okungukuthi ngocingo endlebeni yakho, noma usebenzise ama-headphone e-TWS, ngokuvamile akhuphukayo. Nokho, ukusebenzisa amakhompuyutha kuhlukile, futhi ngenhlanhla i-Apple isenayo indawo yesixhumi sikajekhi esingu-3,5 mm kuwo. Kodwa uma bengingabheja, iMacBook Air yesizukulwane sesi-3 ene-Apple Silicon chip ngeke isayinika.
Ngizozivumela ingxabano encane nombhali. Kimina kubonakala sengathi ijekhi engu-3,5" isafana: ukuxhuma komshini kozakwabo kanye nokuxhumana kwabathintwayo. Ukutholwa okubikiwe nokunye okunjalo, akuyona yini into ye-elekthronikhi?
Ijekhi engu-3,5mm isafana. ayinazo "izinguqulo" nge-impedance. Lapha i-Macbook kufanele ilinganise noma ithole ulwazi ngayo ngesiteshi esithile sedatha/ngocingo...futhi njengoba ujeke we-3,5mm unganikezi lutho olunjalo, cishe uzoyikala ngokuqondile. Ngemuva kwakho konke, ikhebula ngokwalo linokuphazamiseka okuthile, ngakho-ke kufanele kucatshangelwe (yize lizobe lincane kakhulu uma liqhathaniswa namahedfoni)
