Ii-headphones ezisusa ingxolozitekhnoloji yeaudio ephucukileyo eyehlisa ngokuphawulekayo ingxolo yendawo engafunekiyo, inika abasebenzisi amava okuphulaphula ngokuntywilisayo. Oku bakuphumeza ngenkqubo ebizwa ngokuba yi-Active Noise Control (ANC), ebandakanya amacandelo e-elektroniki aphucukileyo asebenzisanayo ukuchasana nezandi zangaphandle.
Indlela Ubuchwephesha be-ANC obusebenza ngayo
Ukufunyanwa kwesandi: Iimakrofoni ezincinci ezifakwe kwii-headphones zibamba ingxolo yangaphandle ngexesha langempela.
Uhlalutyo lweMiqondiso: Iprosesa yesignali yedijithali ekwibhodi (DSP) ihlalutya ubuninzi bengxolo kunye nobukhulu.
IsiZukulwana esichasene nengxolo: Inkqubo yenza i-wave yesandi esiphambeneyo (i-anti-ingxolo) efana ne-amplitude kodwa i-180 degrees ngaphandle kwesigaba kunye nengxolo engenayo.
Ukungenelela Okutshabalalisayo: Xa i-anti-ingxolo i-anti-ingxolo idibanisa ingxolo yokuqala, bayacima omnye nomnye ngokuphazamiseka okutshabalalisayo.
Coca Isiphumo somsindo: Umsebenzisi uva kuphela iaudio ecetywayo (efana nomculo okanyeiminxeba yelizwi) ngophazamiso olungephi lwangasemva.
Iintlobo zokuCima ingxolo
Ingxelo ye-ANC: Imakrofoni zibekwe ngaphandle kweekomityi zendlebe, nto leyo eyenza ukuba isebenze ngokuchasene nezandi zefrikhwensi ephezulu njengencoko okanye ukuchwetheza.
Ingxelo ngeANC: Iimakrofoni ngaphakathi kweekomityi zendlebe zijonga ingxolo eshiyekileyo, iphucula ukucinywa kwezandi ezisezantsi-zandi njengeenjini zokuduma.
I-ANC exubeneyo: Indibaniselwano ye-feedforward kunye nengxelo ye-ANC yentsebenzo egqibeleleyo kuzo zonke iifrikhwensi.
Izinto eziluncedo kunye nemida
IiPros:
Ilungele ukuhamba (iinqwelomoya, oololiwe) kunye neendawo zokusebenza ezinengxolo.
Yehlisa ukumamela ngokudinwa ngokunciphisa ingxolo engasemva engatshintshiyo.
Ububi:
Ukungaphumeleli kwizandi zesiquphe, ezingaqhelekanga njengokuqhwaba okanye ukukhonkotha.
Ifuna amandla ebhetri, anokunciphisa ixesha lokusetyenziswa.
Ngokusebenzisa inkqubo yophawu oluphambili kunye nemigaqo yefiziksi,ii-headphones ezisusa ingxoloukwandisa ukucaca komsindo kunye nokuthuthuzela. Nokuba zisetyenziselwa ubugcisa okanye ukuzonwabisa, zihlala zisisixhobo esibalulekileyo sokuthintela iziphazamiso kunye nokuphucula ukugxila.
Ii-headsets ze-ENC zisebenzisa inkqubo yomsindo ephucukileyo ukunciphisa ingxolo yangasemva ngexesha lokufowuna kunye nokudlala kwakhona. Ngokungafaniyo ne-ANC yemveli (Ukucinywa kwengxolo esebenzayo) ejolise ikakhulu kwizandi ezihlala zisezantsi, i-ENC igxile ekwahluleleni nasekucinezeleni ingxolo yokusingqongileyo ukuze kuphuculwe ukucaca kwelizwi kwiimeko zonxibelelwano.
Isebenza njani itekhnoloji ye-ENC
Uluhlu lweeMicrophone ezininzi: Ii-headsets ze-ENC zibandakanya iimakrofoni ezininzi ezibekwe ngobuchule ukuze zibambe zombini ilizwi lomsebenzisi kunye nengxolo ejikelezileyo.
Uhlalutyo lwengxolo: I-chip ye-DSP eyakhelwe-ngaphakathi ihlalutya iphrofayili yengxolo ngexesha langempela, ukwahlula phakathi kwentetho yomntu kunye nezandi zokusingqongileyo.
UkuNcitshiswa kwengxolo okuKhethekileyo: Inkqubo isebenzisa iialgorithms eziguquguqukayo ukucinezela ingxolo yangasemva ngelixa ugcina amaza elizwi .
Itekhnoloji yokuQinisekisa: Ezinye ii-headsets ze-ENC eziphambili zisebenzisa ii-microphone zesikhokelo ukugxila kwilizwi lesithethi ngelixa unciphisa ingxolo ye-axis.
UPhumo lokuPhuhliswa: I-audio ecutshungulwayo ihambisa ukuhanjiswa kwelizwi okucacileyo ngokugcina intetho eqondakalayo kunye nokunciphisa izandi eziphazamisayo ze-ambient.
Iiyantlukwano eziphambili kwi-ANC
Isicelo ekujoliswe kuso: I-ENC igxile ekunxibelelaneni ngezwi (iifowuni, iintlanganiso), ngelixa i-ANC igqwesa kumculo / kwiindawo zokuphulaphula.
Ukuphatha ingxolo: I-ENC ibamba ngokufanelekileyo ingxolo eguquguqukayo njengetrafikhi, ukuchwetheza kwebhodi yezitshixo, kunye nencoko yesihlwele i-ANC esokola nayo.
UGxila ekuqhubeni: I-ENC ibeka phambili ukugcinwa kwentetho endaweni yokurhoxiswa kwengxolo epheleleyo.
Iindlela zokuPhumeza
Idijithali ye-ENC: Isebenzisa i-algorithms yesoftware yokucinezela ingxolo (ixhaphakile kwii-headsets zeBluetooth).
I-Analog ENC: Iqeshe i-hardware-level filtering (ifumaneka kwii-headsets ezinocingo zobuchwephesha).
Imiba yokusebenza
Umgangatho weMibhobho: Ii-mics ezinovakalelo oluphezulu ziphucula ukuchaneka kokubanjwa kwengxolo.
Amandla okuqhuba: Iitshiphusi ze-DSP ezikhawulezayo zenza ukuba kucinywe ingxolo ye-latency esezantsi.
Ubuchule be-algorithm: Iinkqubo ezisekelwe kumatshini wokufunda zilungelelanisa ngcono iimeko zengxolo eguqukayo.
Usetyenziso
Unxibelelwano lweshishini (iminxeba yenkomfa)
Imisebenzi yeziko loqhagamshelwano
Ii-headsets zokudlala ngencoko yelizwi
Imisebenzi yasebaleni kwindawo enengxolo
Itekhnoloji ye-ENC imele indlela ekhethekileyo yolawulo lwengxolo, ilungiselela ii-headsets zokuhanjiswa kwelizwi elicacileyo kunokuphelisa ingxolo ngokupheleleyo. Njengoko umsebenzi okude kunye nonxibelelwano lwedijithali lukhula, i-ENC iyaqhubeka nokuvela ngophuculo oluqhutywa yi-AI ukuze kube lula ukwahlulwa kwelizwi kwiindawo ezingxolayo.
