Oyankhula Osalankhula Mosalankhula:

Cholankhulira chopanda phokoso ndichakuti palibe gwero loyendetsera mkati mwa cholankhulira, ndipo chimakhala ndi kapangidwe ka bokosi ndi cholankhulira chokha. Pali chogawanitsa cha ma frequency otsika kwambiri mkati mwake. Mtundu uwu wa cholankhulira umatchedwa cholankhulira chopanda phokoso, chomwe timachitcha bokosi lalikulu. Cholankhuliracho chimayenera kuyendetsedwa ndi amplifier, ndipo mphamvu yochokera ku amplifier yokha ndi yomwe ingakankhire cholankhuliracho.

Tiyeni tiwone kapangidwe ka mkati mwa olankhula osalankhula.

Wokamba mawu osamveka amakhala ndi bokosi lamatabwa, wokamba mawu wocheperako, wogawa mawu, thonje loyamwa mawu mkati, ndi ma block a speaker terminal. Kuti muyendetse wokamba mawu osamveka, ndikofunikira kugwiritsa ntchito waya wa wokamba mawu ndikulumikiza speaker terminal ku power amplifier output terminal. Volume imayendetsedwa ndi amplifier. Kusankha kwa gwero la mawu ndi kusintha kwa ma tone apamwamba ndi otsika zonse zimamalizidwa ndi amplifier yamagetsi. Ndipo wokamba mawuyo ndiye amene amangoyang'anira phokoso. Pokambirana za okamba, palibe cholembedwa chapadera, nthawi zambiri amakhala okamba mawu osamveka. Okamba mawu osamveka amatha kufananizidwa ndi mitundu yosiyanasiyana ndi mitundu yosiyanasiyana ya ma amplifier amphamvu. Zingakhale zofanana kwambiri.

Bokosi lomwelo, lokhala ndi amplifier yosiyana, momwe nyimbo zimagwirira ntchito si zofanana. Amplifier yomweyi yokhala ndi bokosi losiyana, imakoma mosiyana. Uwu ndiye ubwino wa ma speaker osachitapo kanthu.

Wokamba Nkhani Wogwira Ntchito:

Ma speaker ogwira ntchito, monga momwe dzinalo likusonyezera, ali ndi chipangizo choyendetsera magetsi. Pali gwero loyendetsera. Izi zikutanthauza kuti, pogwiritsa ntchito speaker yosagwira ntchito, magetsi, circuit ya amplifier yamagetsi, circuit yosinthira, komanso circuit yosinthira mawu onse amayikidwa mu speaker. Ma speaker ogwira ntchito amatha kumveka ngati ma speaker osagwira ntchito komanso kuphatikiza ma amplifier.

Pansipa tikuyang'ana kapangidwe ka mkati mwa wokamba nkhani wogwira ntchito.

Wokamba nkhani wogwira ntchitoyo ali ndi bokosi lamatabwa, chipangizo cholankhulira chotsika kwambiri komanso thonje loyamwa mawu mkati, bolodi lokulitsa mawu lamkati ndi mphamvu, komanso chowongolera mawu mkati. Mofananamo, mu mawonekedwe akunja, okamba nkhani wogwira ntchito ndi okamba nkhani osagwira ntchito nawonso ndi osiyana kwambiri. Popeza cholankhulira choyambira chimaphatikiza dera lokulitsa mawu, cholowera chakunja nthawi zambiri chimakhala doko la mawu la 3.5mm, soketi yofiira ndi yakuda ya lotus, mawonekedwe a coaxial kapena optical. Chizindikiro chomwe cholankhulira chogwira ntchito chimalandira ndi chizindikiro cha analog chotsika mphamvu. Mwachitsanzo, foni yathu yam'manja imatha kupeza mwachindunji cholankhulira choyambira kudzera mu mzere wojambulira wa 3.5mm, ndipo mutha kusangalala ndi zotsatira zodabwitsa za mawu. Mwachitsanzo, doko lotulutsa mawu la kompyuta, kapena mawonekedwe a lotus a bokosi lokhazikika, lingakhale okamba nkhani ogwira ntchito mwachindunji.

Ubwino wa spika yogwira ntchito ndi kuchotsa amplifier, amplifier imatenga malo ambiri, ndipo spika yogwira ntchito imagwiritsa ntchito circuit ya amplifier. Zimasunga malo ambiri. Spika yogwira ntchito kuwonjezera pa bokosi lamatabwa, komanso bokosi la alloy ndi zipangizo zina, kapangidwe kake konse ndi kakang'ono kwambiri. Chifukwa chakuti spika yoyambira imakhala ndi malo a bokosi, ndipo malo a bokosi ndi ochepa, silingathe kuphatikiza magetsi ndi dera lachikhalidwe, kotero ma spika ambiri oyambira ndi ma circuit amplifier a D class. Palinso ma spika angapo a AB class omwe amaphatikiza transformer yamagetsi ndi calorimeter mu ma spika oyambira.
