Izikhulumi zanamuhla manje, mhlawumbe, ngayinye - zixhuma kwikhompyutha yomuntu siqu, i-TV, iphathekayo, ifaneleka ukuthatha nayo imvelo. Ngayinye yalezi zinhlobo zamakholomu inezinhloso zayo. Kukhona izikhulumi ezingasebenzi futhi ezikhuthele, ezinye zazo zihlomelelwe ukukhishwa kwe-usb, ngenhloso yokuxhuma kwisixhumi esifanayo. Ake sithole ukuthi yini umehluko wabo kanye nenzuzo yalokhu okuphezu kokuqala noma okuphambene nalokho.
Yiziphi izikhulumi ezisebenzayo?
Abasebenzisi abangafundile abacabangi ngisho nokuthi yiziphi amakholomu ababhekana nazo nsuku zonke. Ngokuvamile lezi ziyikholomu esebenzayo. Kusukela ekuziphatheni kwabo bahlukaniswa iqiniso lokuthi asikho isidingo sokuthenga ngokwehlukile i-amplifier ekhethekile yomsindo, ngenxa yokuthi ikholomu enjalo izosebenza.
I-amplifier inesayizi encane, futhi isivele isakhiwe kusikhulumi, futhi ngezinye izikhathi ibe yizikhulumi ngasinye, ngaleyo ndlela ikhulise umsindo. Le kholomu kulula ukuxhuma kuma-media, kaningi kunomkhiqizo we-usb wokusebenza kusuka kwikhompyutha ephathekayo noma ikhompuyutha futhi uphelele ezimweni eziningi lapho udinga khona umsindo ophezulu.
Kodwa kaningi, i-amplifier ekholomu esebenzayo inamandla amancane kanti nomthwalo wokugcina ungashisa. Le ndlela ayifanelekile lapho udinga khona umsindo onamandla, njengokuthi, ukubuka amabhayisikobho, ukudlala imidlalo kwikhompyutha yakho noma ukuxhuma inkundla yaseshashalazini .
Izipikha ezifanayo, ngokubuka kuqala, zinenkinga ethile, njengoba nazo zidinga ukuthengwa kwe-amplifier ngokungeziwe. Ngaphezu kwalokho, uma umsebenzisi engazi ukuxhuma wonke la madivayisi kuzodingeka ufune isazi sokuxhuma. Kodwa, bane-tangible plus - izikhulumi ezifana nalezi, zihlome nge-amplifier enamandla, futhi zine umsindo omangalisayo.
Ungakhetha kanjani izikhulumi ezisezingeni eliphansi?
Ukuthola izikhulumi ezine-amplifier / ezithuthukisiwe ezakhelwe ngaphakathi, umsebenzisi kufanele anqume amandla azo, kanye nokuthi yiyiphi i-quadrature azosebenza kuyo. Njengoba uma ekamelweni elincane ukuthenga idivayisi enamandla, ngeke kuthinte ikhwalithi engcono kakhulu yomsindo, kodwa kuphela ukuyiphazamisa kakhulu futhi ngeke iphumelele ibe umsindo omuhle kakhulu.
Ngokujwayelekile amakholomu afana nalabo abalaleli nabangezinhlangothi zawo, kodwa hhayi ngokuqondana noma odongeni oluphambene, kodwa nge-angle - lokhu kufanele kucatshangelwe, kucabangela isimo ekamelweni. Ngaphezu kwalokho, izikhulumi ezinjalo zingaba yedwa-, kabili-, futhi ezintathu-ndlela zokulawula okulula okuzwakalayo. Kukhona amafomula akhethekile wokubala amandla amakholomu afana nobukhulu bekamelo.
Kodwa kufanele wazi ukuthi ama-stereosystems aphansi anikeze iphutha elikhulu ngokwanele lomsindo. Enye into - udonga namapulangwe asebenzayo odongeni. Sinamathuba amaningi okudlulisela ngokunembile umsindo ngenxa yedivayisi yabo nendawo. Kubalulekile kuphela ukukhetha okunamandla okunamandla futhi okuphezulu.
Izikhulumi ezisebenzayo zekhompyutha
Imingcele eyinhloko yokukhetha izikhulumi zekhompyutha iphinde ibe namandla futhi indaba yendaba. Ukusebenza ehhovisi akudingi amandla amaningi - okwanele kuzoba ngu-6W, kepha ukusetshenziswa kwekhaya kungcono ukuthenga ikholomu ye-10W. Uma uhlela imidlalo esebenzayo nokubukela amabhayisikobho, izikhulumi ku-20-30 W zifanelekile.
Indaba engcono kakhulu yecala yizinkuni. Kulesi sakhiwo, izintambo zizosebenza, zithole ukungaguquki okungadingekile. Kodwa inani labo liphakeme kakhulu kunezintengo zepulasitiki. Nakuba ukukhetha kokuklama kwezikhulumi zepulasitiki kungaphezu kokuhlukahluka.
Ikhompyutha ephathekayo ivame ukuthengwa ikholomu esebenzayo yomgwaqo ngokuxhumeka kwe-usb. Ayitholakali nganoma yisiphi isidingo esikhulu, ngaphandle komthamo. Ikholomu enjalo ingasetshenziswa kunoma yiziphi izimo, kodwa ekhaya, lizophinde lifinyeleleke, ngoba izikhulumi zekhompyutha ephathekayo zibuthakathaka.
Abakhulumi abakhuthele be-TV
Kusobala ukuthi izikhulumi zethelevishini zenzelwe ukuhanjiswa kwekhwalithi ephezulu. Ithonywa ukuzwela kwezikhulumi, amandla abo, ububanzi obuhlukahlukene, uhlobo lwezindlu. Kungcono kule njongo izinsika ezifanele ezitholakala ezindongeni.
