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 isifunda se-amplifier yamandla siphinde sivalwe ebhokisini, ngoba ibhokisi le-amplifier lamandla alifani nesipikha, akukho mfuneko yokubeka uphawu, ngakho-ke inani elikhulu lemigodi yokushisa ukushisa lingavulwa endaweni yengxenye yokushisa, 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 ibhodi yePCB yesikhulisamandla kanye nezingxenye ze-elekthronikhi kuzwakale, nokudlidliza kwama-capacitor nezinye izingxenye kuzodlalwa kubuyele emsindweni, kubangele 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 azimele, empeleni, angafingqwa emushweni owodwa-uma ungacabangi usayizi, intengo, njll., futhi ucabangele umphumela wokusetshenziswa, khona-ke isikhulisi samandla esizimele singcono kunomklamo we-amplifier eyakhelwe ngaphakathi.
