I-tweeter yesipikha esinezindlela ezimbili inomsebenzi obalulekile webhendi yonke yamafrikhwensi aphezulu.Ingxenye yesikhulumi yayo ye-tweeter ithwala wonke amandla engxenye ye-high-frequency, ukuze wenze le tweeter ingalayishwa ngokweqile, ngakho awukwazi ukukhetha i-tweeter enephuzu eliphansi le-crossover, uma ukhetha iphuzu eliphansi le-crossover lizoholela. ku-tweeter ku-tweeter kuyoba ngamandla amakhulu kakhulu, okuzoholela ekutheni i-tweeter ishiswe, ngaphansi kwezimo ezijwayelekile, iphuzu le-crossover le-tweeter ngeke libe ngaphezu kwe-2,000 hertz!

I-tweeter kufanele futhi isetshenziswe ngokuhambisana ne-woofer.Ngesikhathi esifanayo, sidinga futhi ukucabangela umkhawulo we-tweeter-frequency ephansi, ngaphandle kwalokho, kuzoba nokukhuluma kabi kwamafrikhwensi amabili.Umkhawulo wemvamisa ephezulu yesipika esingu-6.5-intshi ngokuvamile awubi ngaphezu kuka-5,000 Hz, uma siklama indawo enqamulayo, uma sishiya ukuphindwa kabili kwe-frequency, khona-ke leli phuzu le-crossover lephuzu elinengqondo lithatha inani elingaba ngu-2.5000 Hz, ngokufanayo, umkhawulo wefrikhwensi ephansi we-tweeter, uma futhi ngokuya ngekhefu elifanayo ukuphinda kabili kwefrikhwensi yokubala, kufanele kube ngaphansi kuka-1.2500 Hz.Phinda kabili imvamisa yokubala, kufanele ibe ngaphansi kuka-1.2500 Hz.

Ngezidingo ze-tweeter, okokuqala, imvamisa ye-resonant F0 ayikwazi ukuba ngaphezu kwengxenye yemvamisa yephoyinti le-crossover, ngaphandle kwalokho, izoholela endaweni ye-crossover endaweni yokuphendula imvamisa kuzoba yinkinga, ububanzi obuzwakalayo kufanele kube imvamisa yokukhala kwesipikha ayikho ngaphezulu kuka-1.2500 Hz.Uma ubukhulu be-woofer obusekela bungaphansi kwama-intshi angu-6.5, kuleli phuzu, umkhawulo we-tweeter we-low-frequency uzobe uphakeme kancane, ngoba ngalesi sikhathi ikhono le-woofer high-frequency lizothuthukiswa, iphuzu le-crossover lizophakanyiswa, lokhu kusekelwe. ezicini ze-woofer okufanele uzinqume!

Lapho sikhetha i-tweeter, sidinga futhi ukunaka ukuthi ukuzwela, ngokuyisisekelo ukuzwela kwe-tweeter akukwazi ukuba ngaphansi kokuzwela kwe-woofer.Uma iphansi kunayo, kuyoba nzima ukunciphisa ukuzwela kwesikhulumi ngokusebenzisa i-attenuation yesikhulumi esivamile, uma i-crossover ye-electronic, lokhu akubalulekile, lapho ukuzwela kwe-tweeter kuphakeme kunokuzwela kwezikhulumi ze-bass, singakwazi. ngokusebenzisa i-tweeter ochungechungeni lwamanye ama-resistors ahlanganisa izinsiza ezithile ezivimbelayo ukunciphisa kokubili ukuze kuzuzwe inhlanganisela ephelele ye-treble ne-bass.

Into yokugcina okumele siyiveze ukuthi izici ze-tweeter ngokwayo zinomthelela omkhulu kakhulu ohlelweni lonke, ngakho-ke kufanele sihambe futhi sikhethe i-tweeter ngokuhlanekezela okuphansi nokusebenza kahle!
