I-tweeter yesithethi esineendlela ezimbini inomsebenzi obalulekileyo walo lonke iqela le-high-frequency band.Inxalenye yayo ye-tweeter yesithethi ukuba ithwale onke amandla ecandelo le-high-frequency part, ukwenzela ukuba le tweeter ayilayishwanga, ngoko awukwazi ukukhetha i-tweeter ene-low crossover point, ukuba ukhetha i-crossover point ephantsi iya kukhokelela. ku-tweeter kwi-tweeter iya kuba ngamandla amakhulu kakhulu, okuya kukhokelela ekubeni i-tweeter itshiswe, phantsi kweemeko eziqhelekileyo, i-crossover point ye-tweeter ayiyi kuba ngaphezu kwe-2,000 hertz!

I-tweeter kufuneka isetyenziswe ngokubambisana ne-woofer.Kwangaxeshanye, kufuneka sithathele ingqalelo i-tweeter's low-frequency limit, ngaphandle koko, kuya kubakho ukungacaciswa kakuhle kweefrikhwensi ezimbini.Umda we-6.5-intshi ye-high-frequency yesithethi ngokubanzi awukho ngaphezulu kwe-5,000 Hz, xa siyila i-crossover point, ukuba sishiya ukuphindwa kabini kwe-frequency, ke le ndawo ye-crossover yengqiqo ithatha ixabiso elimalunga ne-2.5000 Hz, ngokufanayo, Umda we-low-frequency limit ye-tweeter, ukuba kwakhona ngokwekhefu elifanayo ukuphindaphinda kabini ukubala, kufuneka kube ngaphantsi kwe-1.2500 Hz.Phinda kabini ukuphindaphinda ukubala, kufuneka kube ngaphantsi kwe-1.2500 Hz.

Kwiimfuno ze-tweeter, okokuqala, i-resonant frequency F0 ayinakuba ngaphezulu kwesiqingatha se-frequency ye-crossover point, ngaphandle koko, iya kukhokelela kwindawo ye-crossover kwindawo yokuphendula rhoqo iya kuba yingxaki, uluhlu olufanelekileyo kufuneka lube yi-resonant frequency yesithethi ayikho ngaphezulu kwe-1.2500 Hz.Ukuba ubukhulu be-woofer obuxhasayo bungaphantsi kwama-intshi ama-6.5, ngeli xesha, umda we-tweeter we-low-frequency limit uya kuba phezulu kancinci, kuba ngeli xesha i-high-frequency capability iya kuphuculwa, i-crossover point iya kuphakanyiswa, oku kusekelwe. kwiimpawu ze-woofer ukwenza isigqibo!

Xa sikhetha i-tweeter, kufuneka kwakhona sinikele ingqalelo kubuntununtunu, ngokomgaqo i-tweeter sensitivity ayinakuba ngaphantsi kwe-woofer sensitivity.Ukuba iphantsi kunayo, kuya kuba nzima ukunciphisa uvakalelo lwesithethi ngokusebenzisa i-attenuation yesithethi esiqhelekileyo, ukuba i-crossover ye-elektroniki, oku akubalulekanga, xa uvakalelo lwe-tweeter luphezulu kunovakalelo lwezithethi ze-bass, singakwazi. ngokusebenzisa i-tweeter kuluhlu lwezinye izixhasi ezibandakanya izibonelelo ezithile zokuthintela ukunciphisa ezimbini ukuphumeza ukudibanisa okugqibeleleyo kwe-treble kunye ne-bass.

Into yokugqibela ebonisa ukuba iimpawu ze-tweeter ngokwayo zinempembelelo enkulu kakhulu kwinkqubo yonke, ngoko kufuneka sihambe kwaye sikhethe i-tweeter ngokuphambuka okuphantsi kunye nokusebenza kakuhle!
