Emkhakheni wezikhulumi ze-multimedia, umqondo we-amplifier yamandla ezimele wavela okokuqala ngo-2002. Ngemva kwesikhathi sokukhula emakethe, cishe ngo-2005 nango-2006, lo mbono omusha wokuklama wezikhulumi ze-multimedia uye waqashelwa kabanzi ngabathengi. Abakhiqizi bezikhulumi ezinkulu nabo bethule izikhulumi ezintsha ze-2.1 ezinemiklamo ye-amplifier yamandla ezimele, okuye kwaqala ukuthengwa ngokwesaba "kwama-amplifier amandla azimele". Eqinisweni, empeleni, maqondana nekhwalithi yomsindo wesipika, ngeke ithuthukiswe kakhulu ngenxa yomklamo we-amplifier yamandla ezimele. Ama-amplifier amandla ezimele anganciphisa ngempumelelo kuphela umthelela wokuphazamiseka kwe-electromagnetic kukhwalithi yomsindo, futhi awanele ukubangela ukuthuthuka okukhulu kwekhwalithi yomsindo. Noma kunjalo, umklamo we-amplifier yamandla ezimele usenezinzuzo eziningi ezingenazo izikhulumi ze-multimedia ezivamile ze-2.1:

Okokuqala, i-amplifier yamandla ezimele ayinawo umkhawulo wevolumu eyakhelwe ngaphakathi, ngakho-ke ingafinyelela ukushabalalisa okungcono kokushisa. Izipikha ezivamile ezine-amplifier yamandla ezakhelwe ngaphakathi zingashabalalisa ukushisa kuphela nge-convection yeshubhu ye-inverter ngoba zivalwe ebhokisini lokhuni elinokushisa okubi. Ngokuphathelene ne-amplifier yamandla ezimele, yize isekethe ye-amplifier yamandla nayo ivalwe ebhokisini, ngoba ibhokisi le-amplifier yamandla alifani nesipikha, akukho mfuneko yokuvala, ngakho-ke inani elikhulu lemigodi yokushisa lingavulwa endaweni yengxenye yokushisa, ukuze ukushisa kudlule ku-convection yemvelo. Hlakaza ngokushesha. Lokhu kubaluleke kakhulu kuma-amplifier anamandla aphezulu.

Okwesibili, kusukela esicini se-power amplifier, i-power amplifier ezimele inenzuzo ekwakhiweni kwesekethe. Kuzikhulumi ezivamile, ngenxa yezici eziningi ezifana nomthamo nokuqina, ukwakheka kwesekethe kuncane kakhulu, futhi kunzima ukufeza ukwakheka kwesekethe okulungiselelwe. I-power amplifier ezimele, ngoba inebhokisi le-power amplifier ezimele, inesikhala esanele, ngakho-ke ukwakheka kwesekethe kungaqhubeka ngezidingo zomklamo kagesi ngaphandle kokuphazanyiswa yizici eziqondile. I-power amplifier ezimele inenzuzo ekusebenzeni okuzinzile kwesekethe.

Okwesithathu, kuzikhulumi ezinezikhulisi zamandla ezakhelwe ngaphakathi, umoya osebhokisini uhlala udlidliza, okwenza ibhodi le-PCB le-amplifier yamandla kanye nezingxenye ze-elekthronikhi kuzwakale, futhi ukudlidliza kwama-capacitor nezinye izingxenye kuzodlalwa kuphinde kuzwakale, okubangela umsindo. Ngaphezu kwalokho, isipika sizoba nemiphumela ye-electromagnetic, noma ngabe siyisikhulumi esilwa ngokuphelele ne-magnetic, kuzoba nokuvuza kwe-magnetic okungenakugwenywa, ikakhulukazi i-woofer enkulu. Izingxenye ze-elekthronikhi ezifana namabhodi wesekethe kanye nama-IC zithinteka ukuvuza kwe-magnetic flux, okuzophazamisa ugesi wesekethe, okuholela ekuphazamiseni umsindo wamanje.

Ngaphezu kwalokho, izipikha ezinedizayini ye-power amplifier ezimele zisebenzisa indlela yokulawula ikhabhinethi ye-power amplifier, ekhulula kakhulu ukubekwa kwe-subwoofer futhi igcine isikhala esibalulekile sedeskithophu.

Uma sikhuluma ngezinzuzo zama-amplifier amaningi azimele, empeleni, kungafingqwa ngomusho owodwa - uma ungacabangi ngobukhulu, intengo, njll., futhi ucabangele kuphela umphumela wokusetshenziswa, khona-ke i-amplifier yamandla azimele ingcono kunomklamo we-amplifier yamandla eyakhelwe ngaphakathi.
