Zingaki izinhlobo zobuchwepheshe bokukhansela umsindo wama-headphone ozaziyo?
Umsebenzi Wokukhansela Umsindo ubalulekile kumahedisethi, owokuqala ukunciphisa umsindo, ukugwema ukukhuliswa ngokweqile kwevolumu yesipika, ngaleyo ndlela kunciphe umonakalo endlebeni. Okwesibili ukuhlunga umsindo kumakrofoni ukuze uthuthukise umsindo nekhwalithi yekholi. Kunezindlela eziningi ezahlukene zokufinyelela ukukhanselwa komsindo. Isibonelo, i-ANC,I-ENC, CVC, kanye ne-DSP. Bangaki kubo obaziyo?
Ukukhanselwa komsindo kungahlukaniswa ngokuncishiswa komsindo okwenziwayo kanye nokunciphisa umsindo osebenzayo.
Ukukhanselwa komsindo okungenasici nakho kuwukwesulwa komsindo ongokomzimba, ukuncishiswa komsindo okungenzi lutho kubhekisela ekusetshenzisweni kwezici zomzimba ukuhlukanisa umsindo wangaphandle endlebeni, ikakhulukazi ngomklamo wogongolo lwekhanda le-headset, ukwenza kahle kwe-acoustic yesikhala sendlebe, ukubeka ukumunca umsindo. izinto ezingaphakathi komcamelo wezindlebe… Futhi nokunye ukuze kuzuzwe umsindo ozwakalayo wamahedsethi. Ukuncishiswa komsindo okwenziwayo kusebenza kahle kakhulu ekuhlukaniseni imisindo yefrikhwensi ephezulu (njengamazwi abantu), ngokuvamile kunciphisa umsindo ngo-15-20dB.
Ukukhanselwa komsindo okusebenzayo yilapho amabhizinisi akhangisa umsebenzi wokunciphisa umsindo wama-headphone: i-ANC, i-ENC, i-CVC, i-DSP… Iyini imigomo yalobu buchwepheshe obune bokunciphisa umsindo, futhi iyini indima yabo? Namuhla sizokhuluma ngokuthi zisebenza kanjani nokuthi zihluke kanjani.
I-ANC
I-ANC (I-Active Noise Control) Umgomo osebenzayo ukuthi umbhobho uqoqa umsindo we-ambient wangaphandle, bese uhlelo luguqulela ekubeni igagasi lomsindo elihlehlisiwe bese lilengeza ekugcineni kophondo, futhi umsindo ozwakala endlebeni yomuntu uthi: Umsindo wemvelo + ohlanekezelwe. umsindo wemvelo, izinhlobo ezimbili zomsindo obekwe phezulu ukuze kuzuzwe ukuncishiswa komsindo wezinzwa, ozuzayo nguyena.
I-ENC
I-ENC (I-Environmental Noise Cancellation) ingacindezela ngempumelelo u-90% womsindo we-ambient obuyela emuva, ngaleyo ndlela yehlise umsindo we-ambient ufike ngaphezu kuka-35dB. Ngohlu lwamakrofoni olukabili, umumo wesipikha ubalwa ngokunembile, kuyilapho kuvikela izwi eliqondiwe ohlangothini oluyinhloko, Susa zonke izinhlobo zomsindo wokuphazamiseka endaweni.
I-DSP
I-DSP (ukucubungula isignali yedijithali) ikakhulukazi iqondise phezulu - kanye nomsindo wefrikhwensi ephansi. Ukusebenza
Isimiso siwukuthi imakrofoni iqoqa umsindo wemvelo wangaphandle, bese isistimu ikopisha igagasi lomsindo elibuyela emuva elilingana nomsindo wemvelo wangaphandle, ikhansela umsindo, ngaleyo ndlela izuze umphumela ongcono wokunciphisa umsindo. Umgomo wokunciphisa umsindo we-DSP uyafana nowokunciphisa umsindo we-ANC. Kodwa-ke, umsindo omuhle noma omubi wokunciphisa umsindo we-DSP wenza kancane kancane ohlelweni.
I-CVC
I-CVC(I-Clear Voice Capture) ubuchwepheshe besofthiwe yezwi bokunciphisa umsindo. Iqondise kakhulu ama-echos akhiqizwa ngesikhathi socingo. Isofthiwe ye-full-duplex yokukhansela umsindo wemakrofoni inikeza i-call echo nemisebenzi yokukhansela umsindo ozungezile, okuwubuchwepheshe obuthuthuke kakhulu bokunciphisa umsindo kumahedisethi ezingcingo ze-Bluetooth.
Ubuchwepheshe be-DSP (ukukhansela umsindo wangaphandle) buzuzisa kakhulu umsebenzisi wamahedisethi, kuyilapho i-CVC (ikhansela i-echo) izuzisa kakhulu olunye uhlangothi lwekholi.
I-Inbertec815M/815TMI-AI yokunciphisa umsindo wehedisethi enomsindo ophezulu wemvelo wemakrofoni onciphisa ngokusebenzisa imibhobho emibili, i-algorithm ye-AI ukusika imisindo ngemuva futhi uvumele izwi lomsebenzisi ukuthi lidluliselwe komunye umkhawulo.
