Kuyiniisikhulumi esiphelele?

Ukuqonda ngokugcwele ukuthi yiniisikhulumi esipheleleukuthi, kubalulekile ukufunda ngomsindo womuntu. Imvamisa yomsindo ilinganiswa nge-Hertz (Hz), noma inani lezikhathi lapho isignali yomsindo iphakama khona bese yehla ngomzuzwana. Izikhulumi zekhwalithi zakhiwe ngamaza aphezulu naphansi ezingeni elizwakala endlebeni yomuntu. Indlebe yomuntu iyakwazi ukuzwa wonke amaza kusukela ku-20 Hz kuya ku-20 000 Hz (20 kHz).
Ukuze siqonde lo mqondo, singasho ukuthi izikhulumi ezithile zikhiqiza i-bass eshaya inhliziyo ku-20 Hz kanye nesignali yemvamisa ephezulu kakhulu ku-20 000 Hz (20 Hz). Isikhulumi esiphelele siyakwazi ukukhiqiza iningi lala maza, ngaphakathi kwemikhawulo yemikhawulo yaso yomzimba. Lokho kusho ukuthi ukwakheka kwesipika kungathonya ikhwalithi ye-a isikhulumi esiphelele.
 
Ibanga lokuvama
 
Igama elithi “Full-Range” lisho isikhulumi esihlanganisa lonke ububanzi bezwi lomuntu. Iningi lezikhulumi ezigcwele zinemvamisa ephansi engaba ngu-60-70 Hz. Amayunithi amakhulu anabashayeli abangu-15” azofinyelela amaza aphansi, kuyilapho lawo abashayeli abangu-10” LF noma ngaphansi azodlula eduze kwe-100 Hz. Ububanzi bemvamisa ephezulu yamadivayisi anjalo buvame ukwelula kufika ku-18 kHz. Ngakho-ke, izikhulumi ezincane ezinezishayeli ze-HF eziphansi kakhulu zizoba nobubanzi obude ngaphezu kwezinhlelo zamandla aphezulu. Zine-diaphragm ezisindayo ukuze zihlangabezane nezidingo zazo zamandla. Ububanzi bemvamisa ephansi yalezi zinhlelo ngeke kudingeke ukuthi zenze umsebenzi zodwa ekugcineni okuphansi. Zingase zihlangane nama-subwoofers noma mhlawumbe ziwele ngaphezu kwe-LF cutoff yazo futhi zikhululeke ekudlulisweni kwemvamisa ephansi.
 
Isakhiwo
 
Ngokuvamile, iyunithi yokushayela egcwele ububanzi iqukethe into eyodwa yokushayela, noma ikhoyili yezwi, esetshenziselwa ukuhambisa nokulawula i-diaphragm. Ngokuvamile isakhiwo sekhoyili sihlanganisa ukulungiswa kokuthuthukisa ukusebenza kwemvamisa ephezulu. Isibonelo, uphondo oluncane oluphansi noma ikhoyili ye-Whizzer lungafakwa lapho ikhoyili yezwi ne-diaphragm kuhlangana khona, ngaleyo ndlela kwandiswe umkhiqizo kumaza omsindo aphezulu. Ukuma nezinto ezisetshenziswa kukhoyili ne-Whizzer kulungiselelwe kakhulu.
Kusukela ku-izipikha ezipheleleUma kudingeka ukuthi ibe nempendulo ephezulu nephansi, ihlanganisa lonke uhlobo lomsindo uma kuqhathaniswa nezinye izikhulumi. Uma imvamisa ephezulu, ingafaka ikhoyili yezwi elikhanyayo kanye nomklamo wekhabhinethi wezobuchwepheshe wamaza aphansi. Ingase futhi ibe nezishayeli ezahlukene ukuze kuthuthukiswe ulwazi lwakho lokulalela.

 
Ikhwalithi yomsindo
 
Izipikha eziphelele zinikeza umuzwa omuhle womsindo futhi ikhwalithi ingcono kuneyezipikha eziningi ezisebenzisa izindlela eziningi. Ukususwa kwe-crossover kunikeza lesi sipikha amandla engeziwe okunikeza umuzwa wokulalela ojabulisayo. Ngaphezu kwalokho, kunikeza ikhwalithi nemininingwane ngamathoni aphakathi nendawo. Kodwa-ke, izipikha eziphelele zezentengiselwano zingase zibize kakhulu futhi zingajwayelekile. Kwezinye izimo, abantu abalalelayo kungadingeka bahlanganise amayunithi abo.

Isikhulumi Esigcwele se-H-285
Inzuzo:
1. Umzimba webhokisi usebenzisa amapuleti e-splint kanye nesakhiwo sokuxhuma ipuleti esikhethekile ukuze kuqedwe ukuzwakala komoya ojabulisayo womzimba webhokisi
2. Uhlobo lwemisebe eqondile ye-bass drive ye-long-stroke, umsindo ungokwemvelo futhi uyiqiniso
3.Ibanga elide lokuhlola kanye nencazelo ephezulu
4. Ukuntywila okuvamise ukuvama okuphansi kugcwele futhi kunamandla, futhi kuyaguquguquka
5. Imvamisa ephakathi inamandla futhi ingena kakhulu, kanti imvamisa ephezulu ithambile futhi ayifani nesitayela sendabuko esiphindwe kabili esingamasentimitha angu-15 ubude obuphezulu
6. Amandla okuqhuma aqinile, indawo ezungezile enamandla ephansi kanye nomuzwa wokuba khona
7. Iyunithi yemvamisa ephakathi nendawo enokungena okuphezulu
