Kodi awokamba nkhani?

Kuti mumvetse bwino zomwe awokamba nkhanindiye, ndikofunikira kuphunzira za kamvekedwe ka munthu.Mafupipafupi amawu amayezedwa mu Hertz (Hz), kapena kuchuluka kwa nthawi yomwe siginecha imakwera kenako ndikutsika pakatha mphindi imodzi.Zolankhula zabwino zimamangidwa kumayendedwe apamwamba komanso otsika pamlingo womwe umamveka ndi khutu la munthu.Khutu la munthu limatha kumva ma frequency onse kuchokera pa 20 Hz mpaka 20 000 Hz (20 kHz).
Kuti timvetsetse mfundo imeneyi, tinganene kuti okamba nkhani ena amapanga mabass ogunda pamtima pa 20 Hz ndi siginecha yoboola kwambiri pa 20 000 Hz (20 Hz).Wokamba nkhani wathunthu amatha kupanga zambiri mwama frequency awa, molingana ndi zovuta zake.Izi zikutanthauza kuti kapangidwe ka wokamba nkhani kumatha kukhudza mtundu wa a wokamba nkhani.
 
Nthawi zambiri
 
Mawu akuti “Full-Range” amatanthauza wokamba nkhani amene amafotokoza mitundu yonse ya mawu a munthu.Oyankhula ambiri athunthu amakhala ndi ma frequency otsika a 60-70 Hz.Mayunitsi akulu okhala ndi madalaivala 15 ″ amafika ma frequency otsika, pomwe madalaivala a 10 ”LF kapena kuchepera adzatsika pafupi ndi 100 Hz.Ma frequency amtundu wa zida zotere nthawi zambiri amafikira 18 kHz.Chifukwa chake, oyankhula ang'onoang'ono okhala ndi madalaivala otsika kwambiri a HF adzakhala ndi mwayi wokulirapo pamwamba pa makina amphamvu kwambiri.Ali ndi ma diaphragms olemera kwambiri kuti akwaniritse zofunikira zawo zamagetsi.Mitundu yotsika kwambiri ya machitidwewa sidzafunikanso kugwira ntchito paokha pamapeto apansi.Atha kudutsa ma subwoofers kapena kuwoloka pamwamba pa LF cutoff yawo ndikumasulidwa kumayendedwe otsika.
 
Kapangidwe
 
Nthawi zambiri, gawo loyendetsa lathunthu limakhala ndi chinthu chimodzi choyendetsa, kapena koyilo ya mawu, yomwe imagwiritsidwa ntchito kusuntha ndikuwongolera diaphragm.Nthawi zambiri mawonekedwe a cone amakhala ndi kukhathamiritsa kuti apititse patsogolo magwiridwe antchito apamwamba.Mwachitsanzo, nyanga yaing'ono yotsika kwambiri kapena Whizzer cone imatha kuyikika pomwe koyilo ya mawu ndi diaphragm zimakumana, potero zimawonjezera kutulutsa kwake pama frequency apamwamba.Mawonekedwe ndi zida zomwe zimagwiritsidwa ntchito mu cone ndi Whizzer ndizokongoletsedwa kwambiri.
Kuyambira kuoyankhula athunthuimayenera kukhala ndi mayankho okwera komanso otsika, imakhala ndi ma audio athunthu poyerekeza ndi olankhula ena.Kwa ma frequency apamwamba, chitha kukhala ndi ma coil opepuka a mawu ndi kapangidwe ka kabati ka ma frequency otsika.Itha kukhalanso ndi madalaivala osiyanasiyana kuti muwongolere kumvetsera kwanu.

 
Kumveka bwino
 
Oyankhula amtundu wathunthu amapereka chidziwitso chomveka bwino ndipo khalidweli liri bwino kuposa la oyankhula ambiri.Kuchotsedwa kwa crossover kumapatsa wokamba nkhaniyo mphamvu zambiri kuti apereke kumvetsera kosangalatsa.Kuphatikiza apo, imapereka mtundu komanso tsatanetsatane mumtundu wapakatikati.Komabe, okamba zamalonda amtundu uliwonse amatha kukhala okwera mtengo komanso osowa.Nthawi zina, ma audiophiles angafunikire kusonkhanitsa mayunitsi awo.
