N'ihe gbasara ndị na-ekwu okwu multimedia, echiche nke amplifier ike onwe ya pụtara na mbụ na 2002. Mgbe oge a na-azụlite ahịa gasịrị, n'ihe dị ka afọ 2005 na 2006, echiche ọhụrụ a nke ndị na-ekwu okwu multimedia abụrụla ihe ndị ahịa maara nke ọma. Ndị na-emepụta nnukwu okwu ewebatala ndị na-ekwu okwu 2.1 ọhụrụ nwere atụmatụ amplifier ike onwe ha, nke mere ka ọtụtụ ndị na-azụ "amplifier ike onwe ha" nwee ụjọ. N'eziokwu, n'ihe gbasara ịdị mma ụda ọkà okwu, ọ gaghị aka mma nke ukwuu n'ihi nhazi nke amplifier ike onwe ha. Amplifier ike onwe ha nwere ike ibelata mmetụta nke nnyonye anya eletrọnịkị na ịdị mma ụda nke ọma, ha ezughịkwa ime ka ụda dịkwuo mma. Agbanyeghị, nhazi amplifier ike onwe ha ka nwere ọtụtụ uru nke ndị na-ekwu okwu multimedia 2.1 nkịtị enweghị:

Nke mbụ, amplifier ike nọọrọ onwe ya enweghị oke olu arụnyere n'ime ya, yabụ ọ nwere ike nweta mmụba okpomọkụ ka mma. Ndị ọkà okwu nkịtị nwere amplifier ike arụnyere n'ime ya nwere ike iwepụ okpomọkụ naanị site na convection nke tube inverter n'ihi na a na-emechi ha na igbe osisi na-enweghị ike iguzogide okpomọkụ. Banyere amplifier ike nọọrọ onwe ya, ọ bụ ezie na a na-emechikwa sekit amplifier ike n'ime igbe ahụ, n'ihi na igbe amplifier ike adịghị ka ọkà okwu, enweghị ihe achọrọ maka mkpuchi, yabụ enwere ike imepe ọtụtụ oghere mgbasa okpomọkụ n'ọnọdụ nke ihe na-ekpo ọkụ, ka okpomọkụ wee gafee site na convection eke. Gbasaa ngwa ngwa. Nke a dị mkpa karịsịa maka amplifier ike dị elu.

Nke abụọ, site n'akụkụ nke amplifier ike, amplifier ike nọọrọ onwe ya bara uru maka imewe sekit. Maka ndị ọkà okwu nkịtị, n'ihi ọtụtụ ihe dịka olu na nkwụsi ike, nhazi sekit ahụ dị obere nke ukwuu, ọ na-esikwa ike iru nhazi sekit ka mma. Amplifier ike nọọrọ onwe ya, n'ihi na o nwere igbe amplifier ike nọọrọ onwe ya, nwere oghere zuru oke, yabụ nhazi sekit ahụ nwere ike ịga n'ihu site na mkpa nke imewe eletriki na-enweghị ihe ndị bụ isi na-egbochi ya. Amplifier ike nọọrọ onwe ya bara uru maka arụmọrụ kwụsiri ike nke sekit ahụ.

Nke atọ, maka ndị ọkà okwu nwere amplifiers ike arụnyere n'ime ya, ikuku dị n'ime igbe ahụ na-ama jijiji mgbe niile, na-eme ka bọọdụ PCB nke amplifier ike na ihe ndị ọzọ na-ada ụda, a ga-akpọghachikwa mkpọtụ nke capacitors na ihe ndị ọzọ n'ime ụda ahụ, na-ebute mkpọtụ. Na mgbakwunye, ọkà okwu ahụ ga-enwekwa mmetụta electromagnetic, ọbụlagodi na ọ bụ ọkà okwu na-emegide magnetik kpamkpam, a ga-enwe ntapu magnetik a na-apụghị izere ezere, karịsịa nnukwu woofer. Ihe ndị dị na eletrọniki dị ka bọọdụ sekit na ICs na-emetụta ntapu magnetik, nke ga-egbochi ọkụ eletrik dị na sekit ahụ, na-ebute nsogbu ụda ugbu a.

Tinyere nke ahụ, ndị ọkà okwu nwere imewe ike amplifier nke onwe ha na-eji usoro njikwa kabinet ike amplifier, nke na-eme ka ebe subwoofer dị ukwuu tọhapụ ma na-azọpụta ohere dị mkpa na desktọpụ.

N'ikwu maka uru nke ọtụtụ amplifiers ike nọọrọ onwe ha, n'eziokwu, enwere ike ịchịkọta ya n'otu ahịrịokwu - ọ bụrụ na ị tụleeghị nha, ọnụahịa, wdg, ma tụlee mmetụta ojiji naanị, mgbe ahụ amplifier ike nọọrọ onwe ya ka mma karịa nhazi nke amplifier ike arụnyere n'ime ya.
