Adam Kos Iyo itsva 14- uye 16-inch MacBook Pros ine yakagadziridzwa headphone jack iyo Apple inoti ichagara yakaderera- uye yakakwirira-impedance mahedhifoni asina ekunze amplifiers. Iyo kambani inoburitsa pachena kuti aya ndiwo machina ehunyanzvi emaindasitiri ese, kusanganisira mainjiniya anonzwika uye avo vanonyora mimhanzi paMacBook Pro. Asi chii chichaitika neiyi 3,5 mm jack yekubatanidza?
Apple yakaburitswa pamapeji ayo ekutsigira gwaro idzva, maanonyatso tsanangura zvakanakira iyo 3,5 mm jack yekubatanidza mune itsva MacBooks Pro. Inoti izvo zvitsva zvakashongedzerwa neDC kutaridzika kwekutakura uye adaptive voltage kubuda. Chishandiso ichi chinogona kuona kukanganiswa kwechishandiso chakabatana uye kugadzirisa kuburitsa kwayo kune yakaderera uye yakakwira impedance mahedhifoni pamwe neayo mutsara nhanho yekuteerera.
Zvinogona kudaro kufarira iwe
Vratislav Holub Kana iwe ukabatanidza mahedhifoni ane impedance isingasviki 150 ohms, iyo headphone jack ichapa inosvika 1,25V RMS. Kune mahedhifoni ane impedance ye150 kusvika 1 kOhm, iyo headphone jack inopa 3 V RMS. Uye izvi zvinogona kubvisa kudiwa kweyekunze headphone amplifier. Iine impedance yekuona, inogadzirisa voltage inobuda uye yakavakirwa-mukati-kune-analog converter inotsigira sampuli mareti anosvika 96kHz, unogona kunakidzwa nepamusoro-kutendeseka, kuzere-resolution odhiyo zvakananga kubva kumusoro jack. Uye pamwe zvinoshamisa.
Nhoroondo yakashata ye3,5mm jack yekubatanidza
Yakanga iri 2016 uye Apple yakabvisa 7mm jack yekubatanidza kubva ku iPhone 7/3,5 Plus. Horaiti akatipaku reducer asi yaitova sign yekuti ngatitangei kuti tiende kuconnector iyi. Tichifunga nezvemamiriro ezvinhu neMacs ake uye USB-C yekubatanidza, zvaiita kunge zvine musoro. Asi pakupedzisira, yakanga isiri dema, nekuti tichinayo pamakomputa eMac nhasi. Nekudaro, nezve "mobile" ruzha zvine chekuita, Apple yaive ichiedza kutungamira vashandisi vayo kuti vadyare mu AirPods yayo. Uye akabudirira pane izvozvo.

Iyo 12" MacBook yaingove ne USB-C imwe chete uye imwe 3,5 mm jack yekubatanidza uye hapana chimwe. MacBook Pros yaive nema USB-C maviri kana mana, asi aive achiri akashongedzerwa nehedhifoni jack. Ikozvino MacBook Air ine M1 chip zvakare inayo. Mumunda wemakomputa, Apple yakabatirira pairi zino nezvipikiri. Asi zvinogoneka kuti dai pakange pasina denda rekoronavirus pano, Mhepo ingadai isinawo.
MacBook Mhepo M1
Muchikamu chehunyanzvi, kuvapo kwayo kune musoro uye hazvingave zvine huchenjeri kuibvisa pano. Chero hutambo husina waya hunorasika, uye haudi kuti zviitike munharaunda yehunyanzvi. Asi neyakajairwa mudziyo, kudikanwa kwayo hakudiwi. Dai tairarama munguva dzakajairwa uye kutaurirana kwakaitika sezvazvakaita denda risati raitika, pamwe iyo MacBook Air yaisazove neichi chinongedzo, senge MacBook Pro yaisazove nekuchekwa. Tichiri kurarama munguva umo kukurukurirana kure kwakakosha.
Zvinogona kudaro kufarira iwe
Kumwe kukanganisika kwakaonekwawo mu24 ″ iMac, iyo yakaganhurwa zvakanyanya mukudzika kwayo, uye Apple nokudaro yakaisa chinongedzo ichi padivi rekombuta yayo yese-mu-imwe. Saka zvakakosha kusiyanisa pakati penyika mbiri idzi. Mune nharembozha, unogona kutaura kune rimwe bato zvakananga, i.e. nefoni panzeve yako, kana kushandisa mahedhifoni eTWS, ayo anowanzo kukwira. Nekudaro, kushandisa makomputa kwakasiyana, uye nerombo rakanaka Apple ichine nzvimbo ye3,5mm jack yekubatanidza mairi. Asi dai ndaigona kubheja, chizvarwa chechitatu MacBook Air ine Apple Silicon chip haichaipe.
Ini ndichazvibvumira diki diki nemunyori. Zvinoita kwandiri sekuti iyo 3,5 ″ jack ichiri yakafanana: iyo mechaniki yekubatanidza yeanofanana uye kubatanidzwa kwevanobatika. Kuonekwa kwakashumwa uye zvakadaro, haisi chinhu chemagetsi here?
Iyo 3,5mm jack ichiri yakafanana. haina "shanduro" ne impedance. Pano iyo Macbook inofanirwa kuiyera kana kuwana ruzivo pamusoro payo kuburikidza neimwe data chiteshi / waya ... uye sezvo iyo 3,5mm jack isingapi chero chinhu chakadaro, inogona kuyera iyo zvakananga. Mushure mezvose, tambo pachayo ine imwe impedance, saka inofanirwa kuverengerwa (kunyangwe ingangove isina basa kana ichienzaniswa nemahedhifoni)
