Emkhakheni wezikhulumi ze-multimedia, umqondo we-amplifier yamandla ozimele wavela okokuqala ngo-2002. Ngemva kwesikhathi sokutshala imakethe, cishe ngo-2005 no-2006, lo mbono omusha wokuklama wezikhulumi ze-multimedia uye waqashelwa kabanzi ngabathengi.Abakhiqizi bezipikha ezinkulu baphinde bethula izipikha ezintsha eziyi-2.1 ezinamadizayini azimele wesikhulisi samandla, okususe igagasi lokuthenga “izikhulisi zamandla ezizimele” ngenxa yovalo.Eqinisweni, Eqinisweni, ngokwekhwalithi yomsindo wesipika, ngeke ithuthukiswe kakhulu ngenxa yomklamo we-amplifier yamandla ozimele.Izikhulisamandla ezizimele zinganciphisa kuphela ngempumelelo umthelela wokuphazamiseka kazibuthe kukhwalithi yomsindo, futhi azanele ukudala ukuthuthuka okukhulu kwekhwalithi yomsindo.Noma kunjalo, idizayini ye-amplifier yamandla ezimele isenazo izinzuzo eziningi izipikha ezijwayelekile ze-multimedia engu-2.1 ezingenazo:

Okokuqala, i-amplifier yamandla ezimele ayinakho umkhawulo wevolumu eyakhelwe ngaphakathi, ngakho-ke ingakwazi ukufeza ukuchithwa okungcono kokushisa.Izipikha ezijwayelekile ezinezikhulisamandla ezakhelwe ngaphakathi zingasusa ukushisa kuphela nge-convection ye-inverter tube ngoba zivaliwe ebhokisini lepulangwe eline-thermal conductivity engalungile.Ngokuqondene ne-amplifier yamandla ezimele, nakuba isekethe ye-amplifier yamandla iphinde ivalwe ebhokisini, ngoba ibhokisi le-amplifier lamandla alifani nesikhulumi, asikho isidingo sokuvala, ngakho-ke inani elikhulu lemigodi yokushisa ukushisa lingavulwa esikhundleni. yengxenye yokufudumeza, ukuze ukushisa kudlule ku-convection yemvelo.Zihlakaze ngokushesha.Lokhu kubaluleke kakhulu kuma-amplifiers aphezulu.

Okwesibili, kusukela kusici se-amplifier yamandla, isikhulisi samandla esizimele sinenzuzo ekwakhiweni kwesekethe.Ezikhulumi ezijwayelekile, ngenxa yezici eziningi ezifana nevolumu nokuzinza, umklamo wesifunda uhlangene kakhulu, futhi kunzima ukufeza ukuhlelwa kwesifunda okulungiselelwe.I-amplifier yamandla ezimele, ngoba inebhokisi le-amplifier lamandla elizimele, inendawo eyanele, ngakho-ke umklamo wesifunda ungaqhubeka nezidingo zomklamo kagesi ngaphandle kokuphazanyiswa yizici ezihlosiwe.I-amplifier yamandla ezimele inenzuzo ekusebenzeni okuzinzile kwesekethe.

Okwesithathu, ezipikheni ezinezikhulisamandla ezakhelwe ngaphakathi, umoya osebhokisini uhlala udlidliza, okubangela ukuthi ibhodi yePCB yesikhulisamandla kanye nezingxenye ze-elekthronikhi kuzwakale, nokudlidliza kwama-capacitor nezinye izakhi kuzodlalwa kubuyele emsindweni, okuholela ekutheni umsindo.Ngaphezu kwalokho, isikhulumi sizophinde sibe nemiphumela ye-electromagnetic, ngisho noma isikhulumi esiphikisana nozibuthe ngokugcwele, kuyoba nokuvuza okungenakugwemeka okungenakugwenywa, ikakhulukazi i-woofer enkulu.Izingxenye ze-elekthronikhi ezifana namabhodi wesifunda kanye nama-ICs zithintwa ukuvuza kwe-magnetic flux, okuzophazamisa ukusebenza kwamanje kumjikelezo, okuholela ekuphazamiseni umsindo wamanje.

Ngaphezu kwalokho, izikhulumi ezinomklamo ozimele we-amplifier wamandla zisebenzisa indlela yokulawula ikhabhinethi ye-amplifier, ekhulula kakhulu ukubekwa kwe-subwoofer futhi igcine isikhala esibalulekile sedeskithophu.

Ekhuluma ngezinzuzo zama-amplifiers amaningi azimele, empeleni, angafingqwa ngomusho owodwa-uma ungacabangi usayizi, intengo, njll., futhi ucabangele umphumela wokusetshenziswa, khona-ke isikhulisi samandla esizimele singcono. kunomklamo we-amplifier eyakhelwe ngaphakathi.
