Adam Kos MacBook Pros atsopano a 14- ndi 16-inch ali ndi jackphone yam'mutu yomwe Apple imati izikhala ndi mahedifoni otsika komanso apamwamba opanda zokulitsa zakunja. Kampaniyo ikuwonetseratu kuti awa ndi makina odziwa ntchito m'mafakitale onse, kuphatikiza mainjiniya amawu ndi omwe amapanga nyimbo pa MacBook Pro. Koma chidzachitike ndi chiyani ndi cholumikizira cha 3,5 mm jack?
Apple idatulutsidwa pamasamba ake othandizira chikalata chatsopano, momwe amafotokozera bwino ubwino wa cholumikizira cha 3,5 mm jack mu MacBooks Pro yatsopano. Imanena kuti zatsopanozi zili ndi kuzindikira kwa katundu wa DC komanso kutulutsa kwamagetsi osinthika. Chipangizocho chimatha kuzindikira kutsekeka kwa chipangizo cholumikizidwa ndikusintha zomwe zimatuluka pamahedifoni otsika komanso apamwamba komanso zida zamawu amzere.
Izo zikhoza kukhala chidwi inu
Vratislav Holub Mukalumikiza mahedifoni okhala ndi chotchinga chochepera 150 ohms, chojambulira chamutu chidzapereka mpaka 1,25V RMS. Kwa mahedifoni okhala ndi cholepheretsa cha 150 mpaka 1 kOhm, chojambulira chamutu chimapereka 3V RMS. Ndipo izi zitha kuthetsa kufunikira kwa amplifier yakunja yamakutu. Ndi kuzindikira kwa impedance, kutulutsa kwamagetsi osinthika komanso chosinthira cha digito-to-analogi chomwe chimathandizira mitengo yazitsanzo mpaka 96kHz, mutha kusangalala ndi kukhulupirika kwambiri, zomvera zonse molunjika kuchokera pa jackphone yam'mutu. Ndipo mwina ndizodabwitsa.
Mbiri yoyipa ya cholumikizira jack 3,5mm
Munali 2016 ndipo Apple idachotsa cholumikizira cha 7mm pa iPhone 7/3,5 Plus. Zedi, adatinyamula zochepetsera, koma zinali kale chizindikiro kuti tiyambe kutsazikana ndi cholumikizira ichi. Poganizira momwe zinthu zinalili ndi Macs ake ndi cholumikizira cha USB-C, zidawoneka zomveka. Koma pamapeto pake, sizinali zakuda, chifukwa tidakali nazo pamakompyuta a Mac lero. Komabe, ponena za mawu a "mafoni", Apple ikuyesera kuwongolera ogwiritsa ntchito ake kuti agwiritse ntchito ma AirPods ake. Ndipo anakwanitsa zimenezo.
Zithunzi
12" MacBook inali ndi USB-C imodzi yokha ndi cholumikizira jack 3,5 mm ndipo palibenso china. MacBook Pros anali ndi ma USB-C awiri kapena anayi, koma anali ndi jackphone yam'mutu. MacBook Air yamakono yokhala ndi M1 chip ilinso nayo. M'munda wamakompyuta, Apple ikugwirabe dzino ndi msomali. Koma ndizotheka kuti pakadapanda mliri wa coronavirus pano, Air sakadakhala nawo.
Macbook Air M1
Pagulu la akatswiri, kupezeka kwake ndikomveka ndipo sikungakhale kwanzeru kuchotsa pano. Kutumiza kulikonse kopanda zingwe ndikotayika, ndipo simukufuna kuti izi zichitike muukadaulo. Koma ndi chipangizo wamba, kufunikira kwake sikofunikira. Tikadakhala m'nthawi yabwinobwino ndipo kulumikizana kunachitika monga momwe zidalili mliriwu usanachitike, mwina MacBook Air sikanakhalanso ndi cholumikizira ichi, monganso MacBook Pro sikanakhala ndi chodula. Tikukhalabe m’nthawi imene kulankhulana kwakutali n’kofunika kwambiri.
Izo zikhoza kukhala chidwi inu
Kusagwirizana kwina kumawonekanso mu 24 ″ iMac, yomwe ili yochepa kwambiri pakuzama kwake, ndipo Apple idayika cholumikizira ichi kumbali ya kompyuta yake yonse. Choncho ndikofunikira kusiyanitsa pakati pa maiko awiriwa. Mu foni yam'manja, mutha kuyankhula ndi gulu lina mwachindunji, mwachitsanzo ndi foni kukhutu, kapena kugwiritsa ntchito mahedifoni a TWS, omwe nthawi zambiri akukwera. Komabe, kugwiritsa ntchito makompyuta ndikosiyana, ndipo mwamwayi Apple akadali ndi malo a 3,5 mm jack cholumikizira mkati mwake. Koma ndikadabetcha, m'badwo wachitatu wa MacBook Air wokhala ndi Apple Silicon chip sichidzaperekanso.
Ndidzilola ndekha kangapo kakang'ono ndi wolemba. Zikuwoneka kwa ine kuti 3,5 ″ jack akadali yemweyo: kulumikizana kwamakina kwa mnzake ndi kulumikizana kwa omwe amalumikizana nawo. Kuzindikiridwa konenedwa ndi izi, sizinthu zamagetsi?
Jack 3,5mm akadali yemweyo. alibe "matembenuzidwe" ndi impedance. Pano Macbook iyenera kuyeza kapena kupeza zambiri za izo kudzera mu njira ina ya data / waya ... ndipo popeza jack 3,5mm sichipereka chirichonse chonga icho, mwinamwake idzayesa mwachindunji. Kupatula apo, chingwecho chimakhala ndi cholepheretsa, chifukwa chake chiyenera kuganiziridwa (ngakhale mwina chingakhale chopanda pake poyerekeza ndi mahedifoni)
