Eli nqaku liza kukwazisa ukuba yintoni i-radiator engasebenziyo

I-Passive radiator yinkqubo yesandi esebenzisa "i-passive radiator" idla ngokuba neyunithi yesithethi esebenzayo kunye neyunithi engasebenziyo (i-passive radiator). Iyunithi engasebenziyo idla ngokufana neyunithi yesithethi esebenzayo, kodwa ayinayo i-voice coil okanye i-drive magnet.

Ii-radiator ezingasebenziyo zihlala zijongwa ngabasebenzisi abangenalwazi njengeemveliso zabavelisi besandi abasika iikona. Ijongeka njengeyunithi yebhesi eqhelekileyo; Kodwa ngaphakathi, isakhiwo sahlukile kakhulu. Akukho zikhonkwane zinamathele kuyo, kwaye akukho magnethi aqhelekileyo okuqhubayo ngasemva. Abanye abavelisi kunye nabathengisi bade bayichaze njenge "bass enkulu kwisithethi" okanye "double bass." Kodwa eneneni, ayivelisi bass enamandla.

Kutheni ke sisebenzisa ii-radiator ezingasebenziyo? Yintoni leyo? Zithini iingenelo zokuba nazo kwisithethi?

Singathelekisa i-radiator engasebenziyo "nobunzima" obongezwe kwi-"spring." I-spring "ineendandatho ze-diaphragm emaphethelweni esitya sephepha kunye nomoya ovalekileyo ebhokisini." "Ubunzima" benziwe ngesitya sephepha kunye nobunzima obuchaseneyo. I-counterweight yinxalenye ebalulekileyo kuyilo lwe-radiator engasebenziyo, enxulumene ngokuthe ngqo nesiphumo sokugqibela sesandi.

I-radiator engasebenziyo inokwenza isandi ngokutshintsha i-counterweight, njenge-tuning fork. Nangona kunjalo, ngokungafaniyo nee-tuning fork, ukungcangcazela kwee-radiator ezingasebenziyo akuboli ngokukhawuleza ngaphakathi komgama othile kude ne-resonant frequency. Ii-radiator ezingasebenziyo zihlala zibolile ngesantya se-18db nge-octave nganye. Nangona i-curve ibonakala inyuka, isabonelela ngethoni eluncedo yesiqingatha sesibhozo kwisithethi. Oku kuyivumela ukuba yenzelwe ukuba isandi sivakale kubunzulu obungaphaya kokufikelela kwe-woofer yesithethi, ngaphandle "kokuqhawula" okukhulu phakathi kwesandi se-woofer kunye nese-radiator engasebenziyo, okubangela i-audio curve egudileyo ukusuka phezulu ukuya ezantsi.

Ngokubanzi, ii-radiator ezingasebenziyo ziyangcangcazela njengee-levers: xa isitya sephepha se-woofer sisiya ngaphandle, isitya saso sephepha siya ngaphakathi; Okanye xa isitya sephepha se-woofer sisiya ngaphakathi, isitya saso sephepha siya ngaphandle. Kodwa akunjalo. Isitya se-basso kunye nesitya se-radiator esingasebenziyo sinokungena ngaphakathi okanye ngaphandle ngaxeshanye (oku kubizwa ngokuba "kwisigaba"), okanye indibaniselwano yeentshukumo ezichaseneyo ("ngaphandle kwesigaba "- umzekelo ogqithisileyo" ungaphandle kwesigaba se-180 degrees", njengoko kukhankanyiwe ngaphambili nge-lever). Ngokwethiyori, ukuze izandi ezimbini zihlangane, kufuneka zihambe ngesigaba esingqongqo. Nangona kunjalo, ngenxa yemida yomzimba, kwiimeko ezininzi kukho intshukumo encinci eyahlukileyo kwiinkqubo ezinjalo ze-resonance.

Enye yeenzuzo ezinkulu zeenkqubo zesandi ezixhotyiswe ngee-radiator ezingasebenziyo kukuba zinokutshintsha umthwalo wokuvelisa i-bass ukusuka kubukhulu obuncinci be-woofer ukuya kubukhulu obukhulu be-radiator engasebenziyo (i-woofer idinga umfutho ophezulu womoya kwindawo ethi "-3dB" ukuvelisa isandi esifanayo kuluhlu lwee-frequency). Kule ndawo, i-radiator engasebenziyo inokwenza ukungcangcazela okuthe kratya (intshukumo ephindaphindayo yesitya sephepha ngaphakathi nangaphandle). Enye inzuzo ecacileyo kukuba indawo yokuphendula nge-frequency ephantsi iphantsi kakhulu. Ukongeza, ubungakanani obuncinci beyunithi ye-bass bungasetyenziswa kuyilo, ukuze impendulo ye-bass kunye ne-mid-frequency ibe ngokuchanekileyo ngakumbi, ukwahlula okungcono.
