Kodi ndi chiyaniwokamba nkhani wathunthu?

Kuti mumvetse bwino zomwewokamba nkhani wathunthuNdikofunikira kudziwa za mawu a munthu. Mafupipafupi a mawu amayesedwa mu Hertz (Hz), kapena kuchuluka kwa nthawi zomwe chizindikiro cha mawu chimakwera kenako nkutsika mkati mwa sekondi imodzi. Ma speaker abwino amapangidwa kuti akhale ndi ma frequency apamwamba komanso otsika pamlingo womwe umamveka ku khutu la munthu. Khutu la munthu limatha kumva ma frequency onse kuyambira 20 Hz mpaka 20 000 Hz (20 kHz).
Kuti timvetse lingaliro ili, tinganene kuti ma speaker ena amapanga bass yogunda mtima pa 20 Hz komanso chizindikiro chapamwamba kwambiri pa 20 000 Hz (20 Hz). Wokamba nkhani wathunthu amatha kupanga ma frequency ambiri awa, mkati mwa malire ake. Izi zikutanthauza kuti kapangidwe ka wokamba nkhani kangakhudze mtundu wa wokamba nkhani wathunthu.
 
Mafupipafupi osiyanasiyana
 
Mawu akuti "Full-Range" amatanthauza wokamba nkhani amene amakhudza mawu onse a munthu. Okamba nkhani ambiri okhala ndi ma frequency ochepa a pafupifupi 60-70 Hz. Mayunitsi akuluakulu okhala ndi ma driver a 15” amafika pama frequency otsika, pomwe a ma driver a 10” LF kapena kuchepera amafika pa 100 Hz. Ma frequency apamwamba a zida zotere nthawi zambiri amafika pa 18 kHz. Chifukwa chake, ma speaker ang'onoang'ono okhala ndi ma driver a HF otsika kwambiri amakhala ndi ma frequency owonjezera pamwamba pa ma power system amphamvu kwambiri. Ali ndi ma diaphragm olemera kuti akwaniritse zosowa zawo zamphamvu. Ma frequency otsika a ma computer awa sadzafunika kuti agwire ntchito okha pansi. Angaphatikize ma subwoofers kapena mwina kuwoloka pamwamba pa LF cutoff yawo ndikuchepetsa ma frequency ocheperako.
 
Kapangidwe kake
 
Kawirikawiri, chipangizo choyendetsera galimoto chokhala ndi dalaivala wathunthu chimakhala ndi chinthu chimodzi choyendetsera galimoto, kapena voice coil, chomwe chimagwiritsidwa ntchito kusuntha ndikuwongolera diaphragm. Nthawi zambiri kapangidwe ka kondomu kamaphatikizapo kukonza bwino kuti ziwongolere magwiridwe antchito apamwamba. Mwachitsanzo, nyanga yaying'ono yotsika kapena kondomu ya Whizzer ikhoza kuyikidwa pomwe voice coil ndi diaphragm zimakumana, motero zimawonjezera kutulutsa kwa kondomu pama frequency apamwamba. Mawonekedwe ndi zinthu zomwe zimagwiritsidwa ntchito mu kondomu ndi Whizzer zimakonzedwa bwino kwambiri.
Popezaokamba nkhani athunthuimafunika kukhala ndi mayankho apamwamba komanso otsika, imakhudza mitundu yonse ya mawu poyerekeza ndi ma speaker ena. Pa ma frequency apamwamba, ikhoza kukhala ndi coil yopepuka ya mawu ndi kapangidwe ka kabati kaukadaulo ka ma frequency otsika. Ikhozanso kukhala ndi ma driver osiyanasiyana kuti muwongolere luso lanu lomvetsera.

 
Ubwino wa mawu
 
Ma speaker a Full Range amapereka chidziwitso chabwino cha mawu ndipo khalidwe lake ndi labwino kuposa la ma speaker ambiri omwe amagwiritsa ntchito njira zambiri. Kuchotsa crossover kumapatsa speaker iyi mphamvu zambiri kuti ipereke chidziwitso chosangalatsa chomvetsera. Kuphatikiza apo, imapereka chidziwitso chabwino komanso tsatanetsatane m'mawu apakati. Komabe, ma speaker a Full Range ogulitsa angakhale okwera mtengo ndipo ndi osowa. Nthawi zina, anthu okonda mawu angafunike kupanga mayunitsi awoawo.

Wokamba Nkhani Wonse wa H-285
Ubwino:
1. Thupi la bokosi limagwiritsa ntchito mbale zopindika ndi kapangidwe kapadera kolumikizira mbale kuti athetse kugwedezeka kodzisangalatsa kwa thupi la bokosi
2. Mtundu wa radiation ya bass yoyendetsedwa ndi stroke yayitali, phokoso lake ndi lachilengedwe komanso loona
3. Mtunda wautali wa ziwonetsero ndi tanthauzo lalikulu
4. Kusambira pansi pafupipafupi kumakhala kodzaza ndi mphamvu, komanso kosinthasintha
5. Ma frequency apakati ndi amphamvu komanso olowera kwambiri, ndipo ma frequency apamwamba ndi ofooka komanso osiyana ndi kalembedwe kachikhalidwe kawiri ka mainchesi 15 ka high-frequency rough
6. Mphamvu yolimba yophulika, kuzungulira kwamphamvu kotsika komanso kumva kuti pali
7.Galimoto yapakati pafupipafupi yokhala ndi malo olowera kwambiri
