I-Los Amahedfoni we-Bluetooth Akuzona izinguquko ezinkulu zekhulu lethu leminyaka, kodwa kumelwe sivume ukuthi zenze ukuphila kwethu kwaba lula. Futhi ukuthi, nakuba ama-headphones anentambo ayengenaphutha, kwakungemnandi neze ukuchitha imizuzu embalwa uqaqa amafindo ngaphambi kokukwazi ukulalela ingoma. Umqondo we-'True Wireless' uzohlala, kodwa ama-headphone asenezinkinga eziningi ezisalindile, njengoba kwenzeka ithimba, lo ukwehla kwekhwalithi noma i ukungahambisani kwe-codec.
Ingabe ama-headphone anentambo angcono kune-Bluetooth?
Kungase kubonakale kungamanga, kodwa kungakhathaliseki ukuthi ubuchwepheshe buthuthuka kangakanani, kunezixazululo zesikhathi esidlule eziqhubeka zidlula izinto ezisungulwe manje. Kunezinhlobo eziningi nezigaba zamahedfoni angenantambo, kodwa empeleni, cishe awekho amathrekhi omculo owulalelayo ngenye yalezi zisetshenziswa ezodlula izinga ebesivele sinalo nge-CD yenganekwane.
Ama-headphone anentambo abelinganiselwe ekudluliseleni igagasi lomshini lisuka ekhadini lomsindo lomdlali liye ezindlebeni zethu. Ku khipha ikhebula ku-equation, okufanele uhambe usuka kumakhalekhukhwini wakho uye kumahedisethi amaza kagesi. Ngokulandelayo, lolo lwazi kufanele luguqulwe kudivayisi encane oyifake endlebeni yakho. Lowo ngumsebenzi weDAC. Kodwa into ayigcini lapho. Kuya dlulisa idatha eningi ngesikhathi sangempela usebenzisa i-Bluetooth, iyadingeka cindezela ulwazi. Kulokhu, kusetshenziswa abantu abadumile amakhodekhi. Laba bakamuva banesibopho sokuthi kungase kube negebe phakathi kwalokho okudlalayo nalokho okulalelayo, kanye nencazelo yokuthi kungani ama-AirPod ezwakala kangcono ku-iPhone kunasefonini ye-Android.
ukubambezeleka yinkinga
Uthenga ama-headphone amasha bese uwazama ngefoni yakho. Zinhle ngokulalela i-Spotify noma enye i-podcast. Kepha ngolunye usuku, uthola ukuthi uchungechunge olubukele kuNetflix aluhambisani nomsindo. Le nkinga yenzeka kancane kancane, njengoba ubuchwepheshe buthuthuka. Kodwa-ke, kungenzeka ukuthi kuke kwenzeka kuwe futhi ufuna ukwazi ukuthi ikhona yini indlela yokwenza xazulula le nkinga okucasulayo uma ubuka amafilimu, uchungechunge noma amavidiyo we-YouTube.
Leso sikhala osibonayo phakathi kwezindebe zomlomo nalokhu okuzwayo yisona esidumile i-latency. Isikhathi esinjalo sihlala sikhona, ngisho nalapho sisebenzisa izintambo. Ukubambezeleka kukalwa nge ama-millisecond, futhi ayibonakali nhlobo uma ihamba ngamavelu aphansi. Kodwa-ke, lapho ukubambezeleka kuphezulu, isipiliyoni sokulalela singonakaliswa ngokuphelele.
amakhodekhi
Ihedisethi ngayinye isekela inani le amakhodekhi. Okufanayo kuya kuwo wonke amadivayisi ozowasebenzisa njengomthombo womsindo. Kukhona ama-codec angcono futhi amabi kakhulu, kodwa into ebaluleke kakhulu ukwazi ukuthi i-headphone kanye nedivaysi yokudlala kufanele isekele i-codec efanayo. Ikakhulukazi uma sikhuluma ngemishini ephezulu. Ukwazi ama-codec kubalulekile ukuze ukwazi ukuthola okuningi kumkhiqizo ngamunye futhi ugweme ukubambezeleka okwesabekayo.
I-SBC
Leli zinga lakhiwe ngo-1993, futhi yilona ubuncane bekhodekhi okufanele isekelwe yinoma iyiphi idivayisi ye-Bluetooth. Isebenzisa iphrofayili yomsindo ye-A2DP. Okubi ngale codec ukuthi ukucindezela kwayo kungathuthukiswa kakhulu. Ifinyelela isilinganiso esiphezulu se I-328 kbps, futhi ukukhubazeka kwakhe isithende sakhe se-Achilles.
I-AAC
Kwakuwukuthuthukiswa kwezinkampani ezimbalwa, phakathi kwazo i-AT&T, Nokia kanye ne-Sony, ukubala ezimbalwa. Ikhwalithi yayo yomsindo ingcono kune-SBC, kodwa ukubambezeleka kwayo kubi nakakhulu. Yaduma kakhulu ngenxa ye-Apple ne-YouTube. Naphezu kokuba yizinga elidala, belilokhu lithuthuka eminyakeni edlule, ikakhulukazi esigabeni sokuthumela okungenantambo.
Kule codec singafaka i I-LD-AAC nezinhlobonhlobo zayo, okuyiyona esetshenziswa i-Apple kuma-AirPods ayo. Njengamanje, eziningi zezinkinga zayo zasekuqaleni ziye zaxazululwa ngenxa yokuvela kwayo, futhi kungashiwo ukuthi i-codec ekwazi ukubhekana nezithuthuke kakhulu emkhakheni.
I-Sony LDAC
Yilokho enye yamakhodekhi athuthuke kakhulu esinakho njengamanje. Kuyincazelo yokuthi kungani amahedfoni angenantambo alo mkhiqizo edume njengoba enjalo. Inezinhlobonhlobo ezintathu:
- I-LDAC 330kbps
- I-LDAC 660kbps
- I-LDAC 990kbps
I-Qualcomm aptX
Le codec yaqala ukuthuthukiswa ngeminyaka yama-80s. Ngo-2015, i-Qualcomm yayithatha ukuze iyithuthukise. Batholile izinhlobo ezintathu:
- Ukubambezeleka okuphansi: nge-aptX LL ehlukile. Isekela isilinganiso esingaba ngu-30 ms.
- Ukuchazwa okuphezulu: enokuhluka kwe-aptX HD. Le codec yakhelwe ukulalela umculo. Ukubambezeleka kwenziwa umhlatshelo ukuze kukhuliswe umkhawulo we-bitrate, okuyindinganiso eyeqa ikhwalithi yomsindo we-CD, ekwazi ukukhuphuka ifinyelele ku-576 kbps ku-24 bit kanye no-192 kHz.
- i-adaptive codec: Ikuvumela ukuthi ushintshe phakathi kwe-aptX LL ne-aptX HD kuye ngokuthi sidlala ini, uze ufinyelele amanani amaphakathi.
I-LDHC (Umsindo we-Hi-Res Wireless)
Le codec yakhiwe yi-HWA, futhi iye okuhlukile okubili. Inhlangano isekelwa izinkampani ezibalulekile kulo mkhakha njengeSennheiser, AudioTechnica, Pioneer noma iHuawei. Ikhodekhi iyakwazi ukuletha ubukhulu obungu-900 kbps ku-24 bit kanye no-96 KHz ukubambezeleka okuphansi.
I-LC3
Ivumela i-bitrate phakathi kuka-160 kbps no-345 kbps phakathi kuka-8 no-48 kHz ngokubambezeleka okuphansi kakhulu. Kuyintuthuko ye I-Bluetooth Special Isigcawu Seqembu (OLANDELAYO). Ifakwe ngaphakathi kobuchwepheshe be-Bluetooth LE Audio.
Uzilungisa kanjani izinkinga zokubambezeleka kuma-headphone akho e-Bluetooth
Ezinye izixazululo ezisebenzayo nciphisa ukubambezeleka kwama-headphone akho Yilezi ezilandelayo:
Buyekeza amakhodekhi kuwo womabili amadivayisi
Manje njengoba usuwazi ama-codec abaluleke kakhulu laphaya, thepha khomba lezo ezihambisana nefoni yakho y tus i-headphones.
Uma uneselula endala nama-headphone amasha, inkinga yokubambezeleka ingase ibe khona. Buyekeza isistimu yokusebenza kanye ne-firmware yama-headphone akho. Inhloso yale nqubo ukugwema ukusebenzisa i-codec ejwayelekile kakhulu, okuthi, njengoba indala kakhulu, iyona esebenza kabi kakhulu.
Lungisa kabusha idivayisi
Ngezinye izikhathi, inkinga akuyona kakhulu i-codec njengenkinga ethile. Kufanele ubhangqe idivayisi futhi uma ucabanga ukuthi kunezinkinga zokuxhumeka noma uma uqaphela nje i-latency kwenye yama-headphones amabili.
Gwema ukugxambukela
Njengoba sazi, ukuxhumana nge-Bluetooth kuntekenteke kakhulu. Okokuqala nje, ibanga eliphakeme lapho ngokuvamile isebenza khona Amamitha angu-10. Noma yiziphi izithiyo zingase zibangele ukungasebenzi kahle.
Uma sinamadivayisi athile axhunyiwe futhi asebenzisa i-Bluetooth, angakwazi phazamisa ikhwalithi. Lokhu kungase kubangele ukuphazamiseka futhi kwandise ukubambezeleka lapho ulalela umsindo.
Akuwona wonke ama-mobiles nama-headphone ahambisanayo
Sibuyela esihlokweni esithi amakhodekhi. Wonke umkhiqizi wama-headphone ofuna ukusebenzisa enye yalawo ma-codec amangalisayo esikhulume ngawo esigabeni esedlule, kufanele adlule ebhokisini—uma abanikazi bawo bethengisa amalayisensi, kunjalo. Ama-headphone ashibhe kakhulu asekela kuphela ama-codec amadala. Ukunciphisa ukubambezeleka ngeke kwenzeke. Manje usuyaqonda ukuthi kungani ungathenga ama-headphone angenantambo ejimini ngama-euro ayishumi, akunjalo?
Kodwa nathi singaba nakho inkinga yedivayisi yokudlala. Ungaba nama-headphone amahle kakhulu kanye neselula umkhiqizi wayo ongawakhokhelanga amalayisense okusebenzisa leyo codec. Umphumela? Ihedisethi izosebenza kusetshenziswa i-codec ehlukile. Ngalesi sizathu, ama-AirPod azwakala kangcono kuma-iPhones nama-headphone akwaSony azwakala kahle kunoma iyiphi iselula esekela i-LDAC. Ngezinhlelo, izinto nazo ziyahlukahluka. I-Android ayiwaphathi kahle amakhodekhi, futhi ukungasebenzi kwawo kuyabonakala uma usebenzisa eyodwa edinga kakhulu njenge-AAC.
Ngaphambi kokuthenga ihedisethi ye-Bluetooth, bheka ishidi lefoni yakho futhi ihlaziya kahle ukuthi isekela maphi amakhodekhi. Bese, thola ipheya yama-headphone ahambisanayo. Uma kungenjalo, idivayisi yakho izosebenza nekhodekhi engalungile. Manje uzoyibona kokubili ngekhwalithi kanye ne-latency.
