1.Uhlalutyo lobuchwephesha lweNgxolo eSebenzayo yokuCima ii-headphones
1.1 Uhlalutyo lomgaqo-siseko wokusebenza kwee-headphones zokunciphisa ingxolo esebenzayo Isandi siqulunqwe yi-spectrum ethile kunye namandla.Ukuba isandi sinokufunyanwa, i-frequency spectrum ifana ncam nengxolo yongcoliseko ekufuneka ipheliswe, kodwa isigaba sichasene.I-Superposition kwindawo ethile inokupheliswa ngokupheleleyo.Ingxolo esebenzayo yokurhoxisa ii-headphones zisebenzisa lo mgaqo, ukuphazanyiswa okuphezulu kwamaza omsindo kwisithuba kuphelisa ungcoliseko lwengxolo.Inkqubo ngaphakathi kwe-headphones esebenzayo yokurhoxisa ingxolo iqokelela kwaye ihlalutye ingxolo, kwaye emva koko iqhutywe kwisekethe eyakhelweyo ukuvelisa ngokusebenzayo ingxolo yesigaba esichaseneyo, esinokucinywa kwindawo ethile.Isandi esinezandi ezisezantsi sinamaza esandi amade, ngoko ke kulula ukuphazamisana omnye nomnye esikhaleni, ngoko ke itekhnoloji ye-headphone esebenzayo yokurhoxisa ingxolo inokuphelisa ingxolo ephantsi, kwaye ingasetyenziswa njengokurhoxisa ingxolo. ii-headphones.Imbuyekezo yebhendi yamaza.
2.2 Uhlahlelo lweNkqubo yokuSebenza yeNgxolo yokuCanciswa kwee-Headphones
Kweli nqanaba, ngokomgaqo wokusebenza kunye nesakhiwo soyilo lwee-headphones ezisebenzayo zokurhoxisa ingxolo, zinokwahlulwa zibe ziindidi ezimbini: uhlobo lwengxelo kunye nohlobo lokutya phambili.I-headsets esebenzayo yokunciphisa ingxolo esebenzayo iqulunqwe ikakhulu ngamakrofoni angaphandle, imithombo yesandi sesibini, amacandelo angaphakathi ee-headphones, kunye neesekethe ezisebenzayo zokunciphisa ingxolo ngokuhambisa indawo yokuhambisa isandi kude nomthombo wesandi sesibini.I-port yesandi se-earphone iqokelela ingxolo yangaphandle yendawo.Xa isignali yengxolo iqokelelwa yi-microphone yangaphandle, iya kudluliselwa kumthombo wesandi wesibini ngokusebenzisa isiphaluka solawulo se-ANC, kwaye akukho loop yempendulo.Iiparamitha zayo ezihambelanayo zihlala zilungisiwe, ngoko ke ayikwazi ukwenza uhlengahlengiso olukhawulezayo kunye nolawulo lwesigaba ngokweenguqu kwimo engqongileyo yangaphandle, ngoko ke ukusebenza kwayo kokunciphisa ingxolo esebenzayo kuya kuchaphazeleka yimiba yangaphandle kwaye ingazinzi, kwaye iya kudlala indima kwindawo ethile ezinzileyo. ingxolo.Inokuvelisa isiphumo esihle sokunciphisa ingxolo, kodwa umda wesicelo uya kulinganiselwa kakhulu, kwaye uhlala uvela kuphela kwiimveliso ze-headphone ezisezantsi.Esona sizathu sesokuba i-headphone incinci ngobukhulu, kwaye uyilo lwangaphakathi lwe-headset esebenzayo yokunciphisa ingxolo lunokwenzeka ngokulula.Ingxelo esebenzayo yokurhoxisa ingxolo yee-headphones ikakhulu iqulunqwe yimibhobho yangaphakathi kunye nemithombo yesandi yesibini.Iqulethwe ngamacandelo angaphakathi kwi-earphone kunye nesekethe yokunciphisa ingxolo esebenzayo.I-microphone yangaphakathi ingaphakathi kwi-earphone kwaye ngokuqhelekileyo ibekwe ekungeneni kwe-earcanal.Xa imakrofoni yangaphakathi iqokelela ingxolo engena kwi-earphone, iya kuveliswa yi-ANC yokunciphisa ingxolo yokucubungula isiphaluka.Isigaba sichasene ne-amplitude.Isignali yesandi sesibini esinezandi ezifanayo ekugqibeleni sigqithiselwa kumthombo wesandi sesibini, kwaye ingxolo yesigaba esichaseneyo ikhutshwa ngomthombo wesandi sesibini, ngaloo ndlela iqonda umsebenzi osebenzayo wokunciphisa ingxolo.I-microphone yangaphakathi yempendulo ingxolo esebenzayo yokurhoxisa ii-headphones idla ngokuba kufutshane nomthombo wesandi wesibini.Ngokuqokelela ingxolo kufuphi nomthombo wesandi sesibini, i-loop yempendulo iya kwenziwa kwakhona ngaphakathi kwenkqubo yokunciphisa ingxolo, kwaye iiparamitha zokunciphisa ingxolo ziya kulungelelaniswa.Isikhundla se-microphone yangaphakathi kufuphi nomthombo wesandi sesibini sinokubonakalisa ngokunyanisekileyo ingxolo evakalelwa kufuphi nokuva, ngoko umphumo wokunciphisa ingxolo uya kuba ngcono, kodwa isakhiwo sangaphakathi siya kuba nzima.Ukongezelela, ngenxa yobukho be-loop yengxelo, ukuba inkqubo yokunciphisa ingxolo ayilungiswanga ngokufanelekileyo, iziganeko ezingazinzanga ezifana nokukhala ziya kwenzeka ngokulula, okukwayingxaki ngolu hlobo lweteknoloji yokunciphisa ingxolo esebenzayo.Kwiminyaka yakutshanje, itekhnoloji enxulumene neemveliso zombane kwilizwe lam iye yaphuhliswa ngokukhawuleza nangokukhawuleza, kwaye iteknoloji edibanisa ukondla phambili kunye nengxelo iye ngokuthe ngcembe ibe yingqwalasela yophando.Nangona kunjalo, ngenxa yobukhulu besakhiwo sangaphakathi see-earplugs, ezinye ii-earphones eziphakathi ukuya kwe-low-end kwimarike azikwazi ukusebenzisa ngokufanelekileyo impendulo kunye nobuchwepheshe bokunciphisa ingxolo, kwaye uninzi lwazo lusebenzisa ulwakhiwo lwangaphambili lokutya ukufezekisa ukunciphisa ingxolo.
Kwiminyaka yakutshanje, itekhnoloji yelizwe lam enxulumene nemveliso yombane iphuhliswe ngokukhawuleza nangokukhawuleza, idibanisa ukondla phambili kunye nempendulo.
Itekhnoloji edityanisiweyo iye ngokuthe ngcembe ibe yingqwalasela yophando lwabantu.Nangona kunjalo, ngenxa yobukhulu besakhiwo sangaphakathi see-earplugs, ezinye ii-earphones eziphakathi ukuya kwe-low-end kwimarike azikwazi ukusebenzisa ngokufanelekileyo impendulo kunye nobuchwepheshe bokunciphisa ingxolo, kwaye uninzi lwazo lusebenzisa ulwakhiwo lwangaphambili lokutya ukufezekisa ukunciphisa ingxolo.
