Izipikha Ezingasebenzi:

Isikhulumi esingasebenzisi i-passive siwukuthi akukho mthombo wokushayela ngaphakathi kwesikhulumi, futhi siqukethe kuphela isakhiwo sebhokisi kanye nesikhulumi. Kukhona kuphela isihlukanisi esilula semvamisa ephansi kakhulu ngaphakathi. Lolu hlobo lwesipika lubizwa ngokuthi isikhulumi esingasebenzisi i-passive, okuyilokho esikubiza ngokuthi ibhokisi elikhulu. Isikhulumi sidinga ukuqhutshwa yi-amplifier, futhi amandla avela ku-amplifier kuphela angasunduza isikhulumi.

Ake sibheke isakhiwo sangaphakathi sezikhulumi ezingasebenzi.

Isipikha esingasebenzi sakhiwe ngebhokisi lokhuni, isipikha se-subwoofer, isihlukanisi, ukotini wangaphakathi obamba umsindo, kanye namabhulokhi esipikha. Ukuze ushayele isipikha esingasebenzi, kuyadingeka ukusebenzisa ucingo lwesipikha bese uxhuma isipikha esingasebenzi ku-terminal yokuphuma kwe-amplifier yamandla. Ivolumu ilawulwa yi-amplifier. Ukukhethwa komthombo womsindo kanye nokulungiswa kwamathoni aphezulu naphansi konke kuqedwa yi-amplifier yamandla. Futhi isipikha sinomthwalo wemfanelo womsindo kuphela. Engxoxweni yezipikha, akukho nothi ekhethekile, ngokuvamile izipikha ezingasebenzi. Izipikha ezingasebenzi zingalinganiswa nemikhiqizo ehlukene kanye nezinhlobo ezahlukene zama-amplifier wamandla. Kungaba ukufanisa okuguquguqukayo kakhudlwana.

Ibhokisi elifanayo, eline-amplifier ehlukile, ukusebenza komculo akufani. I-amplifier efanayo enebhokisi lomkhiqizo ohlukile, inambitheka ngendlela ehlukile. Lena inzuzo yezipikha ezingasebenzi.

Isipikha Esisebenzayo:

Izipikha ezisebenzayo, njengoba igama lisho, ziqukethe iyunithi yokushayela amandla. Kukhona umthombo wokushayela. Okusho ukuthi, ngesisekelo sesipikha esingasebenzi, ukunikezwa kwamandla, isekethe ye-amplifier yamandla, isekethe yokulungisa, ngisho nesekethe yokuhlukanisa konke kufakwa kusipikha. Izipikha ezisebenzayo zingaqondwa kalula njengezipikha ezingasebenzi kanye nokuhlanganiswa kwe-amplifier.

Ngezansi sibheka isakhiwo sangaphakathi sesipikha esisebenzayo.

Isipikha esisebenzayo sihlanganisa ibhokisi lokhuni, iyunithi yesipikha ephansi kakhulu kanye nekotini yangaphakathi emunca umsindo, ibhodi le-amplifier yamandla yangaphakathi, kanye nesekethe yokulungisa yangaphakathi. Ngokufanayo, esibonakalayo sangaphandle, izipikha ezisebenzayo nezipikha ezingasebenzi nazo zihlukile kakhulu. Njengoba isipikha somthombo sihlanganisa isekethe ye-amplifier yamandla, okokufaka kwangaphandle kuvame ukuba yi-port yomsindo engu-3.5mm, isokhethi le-lotus elibomvu nelimnyama, i-interface ye-coaxial noma ye-optical. Isignali etholwa yi-spika esisebenzayo iyisignali ye-analog enamandla aphansi ene-voltage ephansi. Isibonelo, ifoni yethu ephathekayo ingafinyelela ngqo isipikha somthombo ngomugqa wokurekhoda ongu-3.5mm, futhi ungajabulela umphumela womsindo oshaqisayo. Isibonelo, i-port yokukhipha umsindo wekhompyutha, noma i-interface ye-lotus yebhokisi le-set-top, ingaba izipikha ezisebenzayo ngqo.

Inzuzo yesipikha esisebenzayo ukususa i-amplifier, i-amplifier ithatha isikhala esiningi, kanti i-amplifier esebenzayo ihlanganisa isekethe ye-amplifier. Igcina isikhala esiningi. Isipikha esisebenzayo ngaphezu kwebhokisi lokhuni, kanye nebhokisi le-alloy nezinye izinto, ukwakheka kwayo konke kuncane kakhulu. Ngenxa yokuthi isipikha somthombo sithatha isikhala sebhokisi, futhi isikhala sebhokisi silinganiselwe, asikwazi ukuhlanganisa ukunikezwa kwamandla nesekethe yendabuko, ngakho-ke iningi lezipikha zomthombo ziyizisekethe ze-amplifier zekilasi le-D. Kukhona nezipikha ezimbalwa zekilasi le-AB ezihlanganisa i-voltage transformer kanye ne-calorimeter kuzipikha zomthombo.
