Pankhani ya olankhula ma multimedia, lingaliro la odziyimira pawokha amplifier adawonekera koyamba mu 2002. Pambuyo pa nthawi yolima msika, chakumapeto kwa 2005 ndi 2006, lingaliro latsopanoli la olankhula ma multimedia ladziwika kwambiri ndi ogula.Opanga ma speaker akulu abweretsanso ma speaker atsopano a 2.1 okhala ndi mapangidwe odziyimira pawokha amplifier, zomwe zayambitsa "zowonjezera mphamvu zodziyimira pawokha" kugula mantha.M'malo mwake, pankhani yamtundu wamawu olankhula, sizingasinthidwe kwambiri chifukwa cha mapangidwe amagetsi odziyimira pawokha.Ma amplifiers odziyimira pawokha amatha kuchepetsa kusokoneza kwamagetsi pamtundu wamawu, ndipo sikokwanira kupangitsa kuwongolera kwakukulu kwamawu.Komabe, mapangidwe odziyimira pawokha amplifier akadali ndi zabwino zambiri zomwe okamba ma multimedia wamba 2.1 alibe:

Choyamba, amplifier yamagetsi odziyimira pawokha alibe malire a voliyumu, kotero amatha kukwaniritsa kutentha kwabwino.Oyankhula wamba okhala ndi zokulitsa mphamvu zomangirira amatha kungotaya kutentha kudzera pa convection ya chubu cha inverter chifukwa amasindikizidwa mubokosi lamatabwa lokhala ndi matenthedwe otsika.Ponena za amplifier yamagetsi odziyimira pawokha, ngakhale kuti dera la amplifier lamagetsi limasindikizidwanso mubokosilo, chifukwa bokosi la amplifier lamphamvu silili ngati wokamba, palibe chofunikira chosindikizira, kotero kuti mabowo ambiri otaya kutentha amatha kutsegulidwa pamalowo. wa chigawo chotenthetsera, kotero kuti kutentha kumatha kudutsa mwachilengedwe.Balikanani msanga.Izi ndizofunikira makamaka kwa amplifiers apamwamba kwambiri.

Kachiwiri, kuchokera ku mbali ya amplifier yamagetsi, amplifier yamagetsi odziyimira pawokha ndiwopindulitsa pakupanga madera.Kwa okamba wamba, chifukwa cha zinthu zambiri monga voliyumu ndi kukhazikika, kapangidwe kadera kamakhala kocheperako, ndipo ndizovuta kukwaniritsa masanjidwe adera okongoletsedwa.Mphamvu yodziyimira payokha yodziyimira payokha, chifukwa ili ndi bokosi lodziyimira payokha la amplifier, lili ndi malo okwanira, kotero mawonekedwe ozungulira amatha kupitilira pazosowa zamagetsi popanda kusokonezedwa ndi zolinga.Mphamvu yodziyimira payokha amplifier imapindulitsa pakukhazikika kokhazikika kwa dera.

Chachitatu, kwa olankhula okhala ndi zokulitsa mphamvu zomangidwira, mpweya womwe uli m'bokosi umakhala ukugwedezeka nthawi zonse, zomwe zimapangitsa kuti PCB board ya amplifier ndi zida zamagetsi zimveke, komanso kugwedezeka kwa ma capacitor ndi zida zina zidzaseweredwanso ndikumveka, zomwe zimapangitsa kuti pakhale phokoso. phokoso.Kuonjezera apo, wokamba nkhaniyo adzakhalanso ndi zotsatira za electromagnetic, ngakhale atakhala ndi anti-magnetic speaker, padzakhala kutayikira kwa maginito kosalephereka, makamaka woofer wamkulu.Zida zamagetsi monga matabwa ozungulira ndi ma ICs zimakhudzidwa ndi kutuluka kwa maginito, zomwe zingasokoneze zomwe zikuchitika m'derali, zomwe zimapangitsa kuti phokoso likhale losokoneza.

Kuphatikiza apo, olankhula omwe ali ndi mapangidwe odziyimira pawokha amplifier amagwiritsa ntchito njira yowongolera kabati ya amplifier, yomwe imamasula kwambiri kuyika kwa subwoofer ndikusunga malo ofunikira apakompyuta.

Kulankhula za ubwino ambiri odziyimira pawokha amplifiers, kwenikweni, akhoza kufotokozedwa mwachidule mu chiganizo chimodzi - ngati simuganizira kukula, mtengo, etc., ndi kungoganizira zotsatira ntchito, ndiye wodziimira mphamvu amplifier ndi bwino. kuposa mapangidwe a amplifier yomangidwa mkati.
