Ama-earphone angenantambo e-Bluetooth alula, ayaphatheka, futhi anamandla kakhulu, kodwa abasebenzisi abaningi basabhekana nemibuzo mayelana nokubhanqa, ikhwalithi yomsindo, ukubambezeleka, impilo yebhethri, kanye nokuhambisana kwedivayisi. Lo mhlahlandlela unikeza izincazelo ezicacile nezisebenzayo ukusiza abasebenzisi baqonde ukuthi ama-earphone e-Bluetooth asebenza kanjani nokuthi bangayithola kanjani ukusebenza okuhle kakhulu kuwo.
1. Kungani ngezinye izikhathi ama-earphone ami e-Bluetooth ehluleka ukubhangqa noma angaxhunywanga?
Izinkinga zokubhanqa zivame ukwenzeka uma isignali ye-Bluetooth iphazamisekile, idivayisi isivele ixhunywe kwenye ifoni noma ikhompyutha, noma lapho inkumbulo yama-earphone isagcina irekhodi elidala lokubhanqa. I-Bluetooth isebenza kubhendi ye-2.4GHz, engathinteka kalula yi-Wi-Fi routers, amakhibhodi angenantambo, noma amanye amadivayisi aseduze. Uma isignali ivama ukuminyana, uxhumano lungase luwe okwesikhashana noma luhluleke ukuqala. Esinye isizathu esivamile ukuthi ama-earbud amaningi e-Bluetooth axhuma kabusha ngokuzenzakalelayo kudivayisi yokugcina ebhanqanisiwe; uma leyo divayisi iseduze ne-Bluetooth yayo ivuliwe, ama-earbud angase abeke phambili ukuxhuma kabusha kuyo esikhundleni sokubhanqa nedivayisi yakho yamanje. Ukuze kulungiswe lokhu, abasebenzisi bangasusa ngesandla amarekhodi amadala e-Bluetooth efonini yabo, basethe kabusha ama-earbud kwimodi yokubhanqa yasefektri, noma basuke ezindaweni ezingenantambo ezinomsindo. Ukuqalisa kabusha i-Bluetooth kuwo womabili amadivayisi kuvame ukuxazulula nokwehluleka kwesikhashana kokuxhawulana.
2. Kungani kukhona ukubambezeleka komsindo lapho ubuka amavidiyo noma udlala imidlalo?
Ama-earphone angenantambo e-Bluetooth adlulisa umsindo ngamaphakethe afakwe ikhodi, kanti ama-codec ahlukene anamazinga ahlukene okulibaziseka. Ama-codec ajwayelekile e-SBC aletha ukubambezeleka okwengeziwe, kuyilapho i-AAC ithuthukisa ukusebenza kwabasebenzisi be-iOS kodwa isengabambezeleka ezimweni zemidlalo. Ama-codec ane-low latency njenge-aptX Low Latency (aptX-LL) noma i-LC3 ku-Bluetooth 5.2 anganciphisa ukubambezeleka kakhulu, kodwa kuphela uma ama-headphone kanye nedivayisi yokudlala kusekela i-codec efanayo. Amaselula ngokuvamile aphatha kahle ukusakaza, kodwa amakhompyutha e-Windows avame ukukhawulelwa ku-SBC noma i-AAC eyisisekelo, okubangela ukubambezeleka okubonakalayo kokuvumelanisa izindebe. Ngaphezu kwalokho, ezinye izinhlelo zokusebenza zethula ukubambezeleka kwazo kokucubungula. Abasebenzisi abadinga umsindo wesikhathi sangempela—wokudlala noma ukuhlela ividiyo—kufanele bakhethe ama-earbud namadivayisi anokusekelwa kwe-low latency codec okufanayo, noma bashintshele kumodi yentambo uma ikhona.
3. Kungani umsindo ungacacile, noma kungani uphenduka uma umsindo uphezulu?
Ukuphambuka komsindo kuvame ukuvela emithonjeni emithathu: amandla amasignali e-Bluetooth aphansi, ukucindezelwa komsindo, kanye nemikhawulo yehadiwe. I-Bluetooth icindezela idatha yomsindo ngaphambi kokuyithumela, futhi ezindaweni ezineziphazamiso, amaphakethe angase awe, okuholela ekuqhekekeni komsindo noma umsindo ongacacile. Kwezinye izimo, abasebenzisi babhekana nokuphambuka ngoba ifayela lomthombo womsindo lisezingeni eliphansi, noma ngoba i-smartphone ine-"volume booster" noma i-EQ eyakhelwe ngaphakathi esunduza amaza angaphezu kwalokho okungakhiqizwa ama-earbud. Izici zehadiwe nazo zibalulekile—abashayeli abancane ngaphakathi kwama-earbud banemikhawulo ebonakalayo, futhi ukuwacindezela kuvolumu ephezulu kungabangela umsindo wokudlidliza noma ukuphambuka kwe-harmonic. Ukuze kugcinwe ukucaca, abasebenzisi kufanele bagweme ukwandisa ivolumu, bagcine ifoni nama-earbud ebangeni eliqondile, bashintshele kuma-codec asezingeni eliphezulu, futhi baqinisekise ukuthi umthombo womsindo ngokwawo awukhuliswa ngokweqile.
4. Kungani uhlangothi olulodwa lwama-earphone luyeka ukusebenza noma luzwakala luthule kunolunye?
Ama-earphone amaningi angenantambo anamuhla ayimiklamo "ye-stereo engenantambo yangempela" (TWS), lapho womabili ama-earbud ezimele, kodwa eyodwa ivame ukusebenza njengeyunithi eyinhloko. Lapho i-earbud yesibili ilahlekelwa ukuvumelanisa ne-primary, ingase inqamule noma idlale ngevolumu encishisiwe. Uthuli, i-earwax, noma umswakama ngaphakathi kwesihlungi se-mesh nakho kungavimba amagagasi omsindo kancane, okwenza uhlangothi olulodwa lubonakale luthule. Ngezinye izikhathi amadivayisi eselula asebenzisa izilinganiso zevolumu ezihlukene zeziteshi zesobunxele nesokudla, okubangela ukungalingani okubonakalayo. Ukusetha kabusha okugcwele kuvame ukuphoqa ama-earbud amabili ukuthi axhumane kabusha, kulungiswe izinkinga zokuvumelanisa. Ukuhlanza i-mesh ngebhulashi elomile kusiza ukubuyisela umsindo ovinjiwe. Abasebenzisi kufanele futhi bahlole izilungiselelo zebhalansi yomsindo kuphaneli yokufinyeleleka kwefoni yabo ukuqinisekisa ukuthi umphumela uphakathi nendawo.
5. Kungani ibhethri liphuma ngokushesha kunalokho okukhangisiwe?
Impilo yebhethri incike kakhulu ezingeni levolumu, inguqulo ye-Bluetooth, izinga lokushisa, kanye nohlobo lomsindo osakazwayo. Ivolumu ephezulu idla amandla amaningi kakhulu ngoba umshayeli kumele asebenze kanzima ngokomzimba. Ukusebenzisa ama-codec athuthukile njenge-aptX HD noma i-LDAC kuthuthukisa ikhwalithi yomsindo kodwa kwandisa ukusetshenziswa kwebhethri. Isimo sezulu esibandayo sinciphisa ukusebenza kahle kwebhethri le-lithium, okubangela ukuphuma ngokushesha. Ngaphezu kwalokho, ukushintsha njalo phakathi kwezinhlelo zokusebenza noma ukugcina ukuxhumana okude kuphoqa ama-earphone ukuthi alungise njalo ukuphuma kwamandla. Abakhiqizi bavame ukukala impilo yebhethri ngaphansi kwezimo ezilawulwayo ngevolumu engu-50%, ngakho-ke ukusetshenziswa kwangempela kuyahlukahluka. Ukuze kwandiswe impilo yebhethri, abasebenzisi kufanele bagcine ivolumu iphakathi, babuyekeze i-firmware, bagweme amazinga okushisa aphezulu, futhi bavale i-ANC (active noise cancelation) uma kungadingeki.
6. Kungani ama-earphone ami e-Bluetooth engakwazi ukuxhuma kumadivayisi amabili ngesikhathi esisodwa?
Akuwona wonke ama-earphone e-Bluetooth asekela ukuxhumana kwama-multipoint. Amanye amamodeli angahambisana namadivayisi amaningi kodwa axhumane nenye ngesikhathi, kuyilapho ama-headset e-multipoint angempela angagcina ukuxhumana okubili ngasikhathi sinye—okuwusizo ekushintsheni phakathi kwe-laptop nefoni. Ngisho noma kusekelwa, ama-multipoint avame ukubeka phambili umsindo wezingcingo kunomsindo wemidiya, okusho ukuthi ukuphazamiseka noma ukubambezeleka kungase kwenzeke lapho kushintsha. Amafoni namakhompyutha angasebenzisa nama-codec ahlukene, okubangela ukuthi ama-earphone ehlise ikhwalithi ye-codec ukuze alondoloze ukuhambisana. Uma ukusetshenziswa kwamadivayisi amabili okungenamthungo kubalulekile, abasebenzisi kufanele babheke ama-earbud akhuluma ngokusobala ngokusekelwa kwama-multipoint ku-Bluetooth 5.2 noma ngaphezulu, bese beqala kabusha ukubhangqa lapho kushintsha izindawo.
7. Kungani umsindo uphuma uma ngizulazula noma ngifaka ifoni yami ephaketheni lami?
Amasignali e-Bluetooth ayahluleka uma edlula emzimbeni womuntu, ezindaweni zensimbi, noma ezintweni ezijiyile. Uma abasebenzisi befaka ifoni yabo ephaketheni labo langemuva noma esikhwameni, imizimba yabo ingavimba indlela yesignali, ikakhulukazi kuma-earbud e-TWS lapho uhlangothi ngalunye lugcina khona isixhumanisi salo esingenantambo. Ukuhamba ezindaweni ezinethrafikhi enkulu ye-Wi-Fi nakho kungandisa ukuphazamiseka. I-Bluetooth 5.0 nezinguqulo zakamuva zithuthukisa ububanzi kanye nokuqina, kodwa zisasengozini yezithiyo. Ukugcina ifoni ohlangothini olufanayo lomzimba njenge-earbud eyinhloko noma ukugcina isignali yomugqa wokubona ngokuvamile kuxazulula lezi zinqamuleli. Amanye ama-earbud avumela abasebenzisi ukuthi bashintshe ukuthi yiluphi uhlangothi olusebenza njengeyunithi eyinhloko, kuthuthukiswe ukuzinza kuye ngemikhuba.
8. Kungani ama-earphone ami engezwakali ngendlela efanayo kumafoni noma izinhlelo zokusebenza ezahlukene?
Amafoni ahlukene asebenzisa ama-Bluetooth chip ahlukene, ama-codec, kanye nama-algorithms okucubungula umsindo. Isibonelo, amadivayisi e-Apple asebenzisa i-AAC ngokwendabuko, kuyilapho amafoni e-Android ehluka kakhulu phakathi kwe-SBC, i-AAC, i-aptX, kanye ne-LDAC. Lokhu kuphumela ekwehlukeni okubonakalayo kokucaca, izinga le-bass, kanye nokubambezeleka. Izinhlelo zokusebenza ezifana ne-YouTube, i-Spotify, i-TikTok, kanye nemidlalo zisebenzisa izendlalelo zazo zokucindezela, okushintsha kakhulu ikhwalithi yomsindo. Amanye amafoni afaka nama-equalizer akhelwe ngaphakathi angakhuphula noma anciphise amaza athile ngokuzenzakalelayo. Ukuze kufezwe umsindo ohambisanayo, abasebenzisi kufanele bahlole ukuthi iyiphi i-codec esebenzayo, bakhubaze ukuthuthukiswa komsindo okungadingekile, futhi basebenzise izinhlelo zokusebenza ezinikeza ukusakaza okuphezulu kwe-bitrate.
