N'ọhịa nke multimedia ọkà okwu, echiche nke nnwere onwe ike ampilifaya mbụ pụtara na 2002. Mgbe oge nke ahịa cultivation, gburugburu 2005 na 2006, a ọhụrụ imewe echiche nke multimedia ọkà okwu na ọtụtụ ndị na-azụ ghọtara. Ndị na-emepụta okwu buru ibu ewepụtala ndị na-ekwu okwu 2.1 ọhụrụ nwere atụmatụ amplifier ike nọọrọ onwe ha, bụ nke wepụrụ ebili mmiri nke ịzụrụ ụjọ “amplifiers nwere onwe”. N'ezie, N'ezie, n'ihe gbasara ụda ụda olu okwu, ọ gaghị eme ka ọ dịkwuo mma n'ihi nhazi nke ụda ike nke onwe ya. Igwe ọkụ ọkụ nọọrọ onwe ya nwere ike ibelata mmetụta nnyonye anya elektrọnik na ogo ụda, ma ezughị oke iji mee ka mmụba dị ukwuu na ogo ụda dị. Ka o sina dị, imewe ampilifaya ike nọọrọ onwe ya ka nwere ọtụtụ uru na ndị na-ekwu okwu mgbasa ozi 2.1 nkịtị enweghị:

Nke mbụ, ụda ike nke onwe ya enweghị njedebe nke arụnyere, ya mere ọ nwere ike nweta nkwụsị ọkụ ka mma. Ndị na-ekwu okwu nkịtị nwere ihe nrụnye ọkụ nwere ike ịgbasa ọkụ site na convection nke tube inverter n'ihi na a na-emechi ha n'ime igbe osisi na-adịghị mma. N'ihe gbasara onye na-eme ihe ike nke onwe ya, ọ bụ ezie na a na-emechikwa sekit amplifier ike n'ime igbe ahụ, n'ihi na igbe ọkụ ọkụ adịghị ka onye na-ekwu okwu, ọ dịghị ihe ọ bụla a chọrọ akara, ya mere enwere ike imeghe ọnụ ọgụgụ dị ukwuu nke oghere ikpo ọkụ ọkụ n'ọnọdụ nke akụrụngwa kpo oku, nke mere na okpomọkụ ahụ nwere ike ịgafe site na convection eke. Gbasaa ngwa ngwa. Nke a dị mkpa karịsịa maka amplifiers dị elu.

Nke abuo, site n'akụkụ nke ike ampilifaya, ike nke onwe ya bara uru imewe sekit. Maka ndị na-ekwu okwu nkịtị, n'ihi ọtụtụ ihe dị ka olu na nkwụsi ike, nhazi sekit dị oke ọnụ, ọ na-esikwa ike iji nweta nhazi nhazi kachasị mma. Igwe ọkụ ọkụ nke onwe ya, n'ihi na ọ nwere igbe nkwuputa ike nke onwe ya, nwere ohere zuru oke, ya mere nhazi nke sekit nwere ike ịga n'ihu site na mkpa nke eletriki eletrik na-enweghị ihe kpatara ya. Igwe nkwuputa ike nke onwe ya bara uru maka ịrụ ọrụ kwụsiri ike nke sekit.

Nke atọ, maka ndị na-ekwu okwu nwere ihe nrụnye ọkụ arụnyere n'ime ya, ikuku dị n'ime igbe ahụ na-ama jijiji mgbe niile, na-eme ka ụda PCB na-eme ka ụda ọkụ na ihe ndị ọzọ na-eme ka ụda na-emegharị, na ụda nke capacitors na ihe ndị ọzọ ga-agbanyeghachi n'ime ụda ahụ, na-akpata mkpọtụ. Na mgbakwunye, onye na-ekwu okwu ga-enwekwa mmetụta electromagnetic, ọ bụrụgodị na ọ bụ onye na-ekwu okwu na-egbochi magnetik zuru oke, a ga-enwe nkwụsị magnet na-apụghị izere ezere, karịsịa nnukwu woofer.

Tụkwasị na nke ahụ, ndị na-ekwu okwu nwere ihe nrịbawanye ike nke onwe ha na-eji usoro njikwa ihe nrịbawanye ike, nke na-atọhapụ nke ukwuu nke subwoofer ma na-echekwa ohere desktọpụ bara uru.

N'ikwu okwu banyere uru nke ọtụtụ ndị na-emepụta ike nke onwe ha, n'eziokwu, enwere ike ịchịkọta ya n'otu ahịrịokwu - ma ọ bụrụ na ị naghị atụle nha, ọnụahịa, wdg, ma na-atụle naanị mmetụta eji eme ihe, mgbe ahụ, ampilifaya nke onwe ya dị mma karịa imewe nke a na-arụ ọrụ ike.
