Yini aisipikha sobubanzi obugcwele?

Ukuze uqonde ngokugcwele ukuthi yini aisipikha sobubanzi obugcweleukuthi, kubalulekile ukufunda ngomsindo womuntu.Imvamisa yomsindo ikalwa nge-Hertz (Hz), noma inombolo yezikhathi lapho isignali yomsindo iphakama bese iwela phakathi nesekhondi.Izipikha ezisezingeni eliphezulu zakhelwe kumafrikhwensi aphezulu naphansi ezingeni elizwakalayo endlebeni yomuntu.Indlebe yomuntu iyakwazi ukuzwa wonke amaza kusuka ku-20 Hz kuya ku-20 000 Hz (20 kHz).
Ukuze siqonde lo mqondo, singasho ukuthi izipikha ezithile zikhiqiza ibhesi eshaya inhliziyo ngo-20 Hz kanye nesignali yefrikhwensi ephezulu yokubhoboza ku-20 000 Hz (20 Hz).Isipikha sobubanzi obugcwele siyakwazi ukukhiqiza iningi lalawa mafrikhwensi, ngaphakathi kwemikhawulo yemikhawulo yaso ebonakalayo.Lokho kusho ukuthi idizayini yesipika ingaba nomthelela kwikhwalithi ye-a isipikha sobubanzi obugcwele.
 
Ibanga lemvamisa
 
Igama elithi “Ibanga Eligcwele” lisho isikhulumi esihlanganisa lonke uhla lwezwi lomuntu.Izipikha eziningi zobubanzi obugcwele zinemvamisa ephansi cishe engu-60-70 Hz.Amayunithi amakhulu anabashayeli abangu-15” azofinyelela kumaza aphansi, kuyilapho lawo abashayeli abangu-10” LF noma ngaphansi azosuka asondele ku-100 Hz.Ibanga le-high-frequency yamadivayisi anjalo ngokuvamile lifinyelela ku-18 kHz.Ngakho-ke, izipikha zefomethi ezincane ezinamadrayivu e-HF anobukhulu obuphansi kakhulu zizoba nesandiso sebanga ngaphezu kwamasistimu anamandla aphezulu.Anama-diaphragm asindayo ukuze ahlangabezane nezidingo zawo zamandla.Ibanga le-low-frequency yalezi zinhlelo ngeke zidingeke ukuthi zenze umsebenzi ngokwazo ekugcineni phansi.Angase adlulele kuma-subwoofers noma awele ngaphezu kwe-LF cutoff yawo futhi akhululeke ekudluliselweni kwefrikhwensi ephansi.
 
Isakhiwo
 
Ngokuvamile, iyunithi yokushayela enobubanzi obugcwele iqukethe isici somshayeli oyedwa, noma ikhoyili yezwi, esetshenziselwa ukuhambisa nokulawula i-diaphragm.Ngokuvamile ukwakheka kwekhoni kufaka phakathi ukulungiselelwa kokuthuthukisa ukusebenza kwemvamisa ephezulu.Isibonelo, uphondo oluncane olunesisindo esiphansi noma ikhoni ye-Whizzer ingafakwa lapho ikhoyili yezwi ne-diaphragm ihlangana khona, ngaleyo ndlela kwandise okukhiphayo kumafrikhwensi aphezulu.Umumo nezinto ezisetshenziswa ku-cone ne-Whizzer zenziwe zangcono kakhulu.
Kusukela iizikhulumi ezigcweleidinga ukuba nakho kokubili impendulo ephezulu nephansi, ihlanganisa i-spectrum yomsindo wonke uma iqhathaniswa nezinye izikhulumi.Ngefrikhwensi ephezulu, ingafaka ikhoyili yezwi elula kanye nomklamo wekhabhinethi wamafrikhwensi aphansi.Ingase futhi ifake abashayeli abahlukahlukene ukuze uthuthukise umuzwa wakho wokulalela.

 
Ikhwalithi yomsindo
 
Izipikha zobubanzi obugcwele zinikeza umuzwa omuhle kakhulu womsindo futhi ikhwalithi ingcono kuneyezipikha ezinezindlela eziningi.Ukuqedwa kwe-crossover kunikeza lesi sipika amandla engeziwe okunikeza umuzwa wokulalela ojabulisayo.Ngaphezu kwalokho, inikeza ikhwalithi nemininingwane kumathoni weleveli emaphakathi.Kodwa-ke, izikhulumi zebanga eligcwele lezentengiso zingabiza futhi azivamile.Kwezinye izimo, ama-audiophiles kungase kudingeke ahlanganise amayunithi awo.

I-H-285 Uhla Olugcwele Isipikha
Inzuzo:
1.Umzimba webhokisi wamukela amapuleti ahlukene kanye nesakhiwo sokuxhuma ipuleti elikhethekile ukuze kuqedwe i-resonance yokuzithokozisa yebhokisi lebhokisi.
I-2.Long-stroke bass drive uhlobo lwemisebe eqondile, umsindo ungokwemvelo futhi uyiqiniso
3.Ibanga elide lokuqagela kanye nencazelo ephezulu
4.I-Low-frequency dive igcwele futhi inamandla, futhi iyavumelana nezimo
5.I-mid-frequency inamandla futhi ingena phezulu, futhi imvamisa ephezulu ithambile futhi iphuma kusitayela esivamile esiphindwe kabili esingu-15-inch high-frequency rough
6.Amandla okuqhuma anamandla, ukuzungeza okunamandla okuphansi kanye nomuzwa wokuba khona
7.Shayela iyunithi ye-mid-frequency enokungena okuphezulu
