Ukuphula iiNkcazo zeMoto
I-Coaxial, okanye uhla olupheleleyo, kunye necandelo ziinkalo ezibini zeentetho ezingasetyenziselwa xa kwakhiwa, okanye ukuphucula, iinkqubo ezizodwa zemoto. Uhlobo oluqhelekileyo sisithethi se-coaxial, esifumaneka malunga nayo yonke inkqubo ye-OEM ye- stereo yemoto ephuma kumgca. Ezi zithethi ziqukethe umqhubi omnye, ezivumela ukuba zivelise uluhlu olubanzi lwee-frequencies. Izithethi ezixubekileyo aziqhelekanga, kodwa i-audiophiles zixhomekeka kuzo xa zakha iinkqubo zomsindo wemoto. Ezi zithethi zenziwa ngamnye ngomqhubi omnye, ngoko zenzelwe ukuvelisa kuphela ukuphakama, ububanzi obuphakathi, okanye amathoni aphantsi.
Ziziphi Iingxoxo Zomlomo?
Uluhlu lwentetho yomntu lu malunga ne-20 ukuya kwi-20,000 i-Hz, kwaye loo mpahla iyahlukana ngokubanzi kwisigaba esahlukileyo kwiinkalo zeteknoloji. Izithethi zeqela ziphethe isahlulo esinye, okanye icandelo, laloluhlu. Ii-frequencies eziphezulu zidalwe yi-tweeters, ezantsi kakhulu nge-woofers, kunye neentetho eziphakathi kweendawo ezifanelekileyo phakathi kwezi zinto ezigqithiseleyo. Ekubeni izithethi zecandelo ngalinye ziqukethe kuphela ikona kunye nomqhubi omnye, zihambelana ngokufanelekileyo kulezo zididi.
Abaxhasi
Ezi zithethi zifihla ukuphela okuphezulu kwesandi sokulalelwayo ukusuka kwi-2,000 ukuya kwi-20,000 iHz. Ingqwalasela eninzi ihlawulwa kwii-bass, kodwa i-tweeters eziphezulu zidlala indima ebalulekileyo ekuzaliseni i-audiocape sound audio. Ezi zithethi zithiwa nge-tweeting ephezulu yeentaka.
Umgangatho ophakathi
Uluhlu oluphakathi lwendawo evelelekayo luqulethwe izandi eziwela phakathi kwe-300 ukuya ku-5 000 i-Hz, ngoko kukho ukungabikho phakathi kweentetho eziphakathi kweekota kunye nee-tweeters.
Woofers
I-bass deep, ewela kwi-40 ukuya ku-1,000 Hz, ilawulwa yi-woofers. Kukho ukudibanisa phakathi kwama-woofers kunye nezipikha eziphakathi kwebalawu, kodwa emacaleni aphakathi akwazi ukuvelisa i-woofs efana neenja ezinika igama labo.
Kukho neengcaphephe ezimbalwa zeengxoxo ezithembisa ukunyaniseka okuthe xaxa kwi-spectrum ye-audio.
AbaPhuphi abakhulu
Ezi zihlandlo ngamanye amaxesha zinako ukuvelisa ii-ultrasonic frequencies ezingaphezu kwebala eliqhelekileyo lokuphulaphula abantu, kwaye iziphelo zazo eziphantsi ziphezulu ngaphezu kwe-2,000 i-Hz ukuba i-tweeters ilandelelana rhoqo. Okuvumela ii-tweeters eziphezulu ukuba zivelise izandi ezivakalayo eziphezulu ngaphandle kokuphazamiseka.
Subwoofers
Njengama-tweeters aphezulu, i- subwoofer yenzelwe ukubonelela ngesandi esiphezulu sogqirha ekupheleni kokuphela komsindo. I-subwoofers yamabanga amabane asebenza ngokubanzi kumgama ukususela kuma-20 ukuya ku-200 iHz, kodwa izixhobo zengxolo zengcali zingapheleliswa kwii-frequencies ezingaphantsi kwe-80 hz.
Ziziphi iiNtetho zeCoaxial?
Izithethi zeCoaxial zibizwa ngokuba zi "iintetho ezipheleleyo" kuba ziyilwe ukuvelisa uluhlu olukhulu lwezandi ezivela kwiyunithi enye. Ezi zithethi ziqulethe iintlobo ezifanayo zeziqhubi ezitholakala kwizithethi zecandelo, kodwa zidibaniswe ukugcina imali kunye nendawo. Uqwalaselo oluqhelekileyo luyi-woofer kunye ne-tweeter ephakanyiswe phezulu, kodwa kukho nezithethi ze-coaxial zendlela ezi-3 eziqukethe i-woofer, ibanga eliphakathi, kunye ne-tweeter.
Izithethi zeenqwelo zeeCoaxial zaziswa ekuqaleni kwee-1970, kwaye ezininzi iinkqubo zomsindo we-OEM zisebenza ngokusetyenziswa kwezithethi ezipheleleyo, kuba i-OEM yemoto yenkqubo yokuyila ibeka phambili ixabiso ngexabiso. Ezi zithethi nazo ziyafumaneka kwiintlobo ezahlukeneyo zabaxhasi bezithuthi zomsakazo, kwaye ukutshintsha izithethi zeenqwelo zefowuni ezinomgangatho ophezulu emva kweeyunithi ze-aftermarket ngokuqhelekileyo kukho ukuphucula ukuphuculwa kwee-car audio .
Ngaba ngaba bathetha iiNtetho okanye abaNxibelelwano beCaxial Better in Cars?
Isithethi ngasinye kunye necoaxial ngasinye sinenzuzo kunye neengxaki, ngoko akukho mpendulo elula kumbuzo obhetele. Ezinye zeengongoma ezinamandla ezinikezelwa ngolu hlobo luquka:
Iithethi ezipheleleyo zodidi lwee-coaxial:
- ngexabiso eliphantsi
- ngokufanelekileyo
- abayidingi i-crossovers
Icandelo:
- mgangatho o phezulu
- ngokwezifiso
Izithethi ezixubileyo zingcono ngokubhekiselele kumgangatho wezandi, kodwa izithethi ezipheleleyo ezipheleleyo zibiza kakhulu kwaye zilula ukuyifaka. Ekubeni iinkqubo ezininzi ze-OEM zisebenzisa izithethi ezipheleleyo ezifanelekileyo, ukuphuculwa ngokuqhelekileyo ngumcimbi wokumane uvele kwizithethi ezintsha .
Ukuba uhlahlo lwabiwo-mali okanye ukulungiswa kokufakela ukuxhalabisa ngokuphambili, izithethi ezipheleleyo ezipheleleyo ziza kuba zikhethileyo. Izithethi ezipheleleyo eziphezulu zezinga eliphezulu zingenako ukufanisa okanye ukubetha izithethi zecandelo, kodwa ziyakwazi ukubonelela ngamava amnandi okuphulaphula.
Nangona kunjalo, izithethi zecandelo zinika ithuba elikhulu lokwenza ngokwezifiso. Ukongeza kwinto yokuba izithethi zecandelo zinika umgangatho ongcono wezandi, isithethi ngasinye sinokuzimela ngokuzimeleyo ukudala i-soundscape efanelekileyo yesithuthi esithile. Ukuba umgangatho omsindo ubaluleke ngaphezu kohlahlo lwabiwo-mali okanye ixesha, izithethi zecandelo yindlela yokuhamba.
