Kuyankha kwa ma frequency otsika kumagwira ntchito yofunika kwambiri m'ma audio system. Kumadziwitsa kuthekera kwa ma audio system kuyankha ma signal otsika, kutanthauza kuchuluka kwa ma frequency ndi momwe ma signal otsika amagwirira ntchito.

Kuchuluka kwa mayankho otsika kukakhala kwakukulu, makina amawu amatha kubwezeretsa bwino mawu otsika, zomwe zimapangitsa kuti nyimbo ikhale yolimba, yeniyeni, komanso yogwira mtima. Nthawi yomweyo, kuyanjana kwa mayankho otsika kumakhudza mwachindunji momwe nyimbo zimamvera. Ngati mayankho otsika sali olinganizidwa, kusokonekera kapena kusokonekera kungachitike, zomwe zimapangitsa kuti nyimbo zizimveka zosagwirizana komanso zosazolowereka.

Chifukwa chake, posankha makina olankhulira, ndikofunikira kuganizira momwe mawu amayankhira pafupipafupi kuti muwonetsetse kuti nyimbo zomveka bwino komanso zoyenda bwino zitha kupezeka.

Wokamba nkhani akakula, amakhala bwino kwambiri.

(Mphamvu yovotera ya TR12: 400W/)

Wokamba nkhani wamkulu wa wokamba nkhani, phokoso la besi lachilengedwe komanso lozama lingapezeke mwa kubwerezanso phokosolo, koma sizitanthauza kuti zotsatira zake zimakhala zabwino. Panyumba, wokamba nkhani wamkulu sagwiritsidwa ntchito konse, monga momwe amachitira ndi mfuti ya AWM sniper mumsewu wawung'ono ndikumenyana ndi thupi la munthu, zomwe sizigwira ntchito bwino kuposa mpeni wopepuka komanso wakuthwa.

Ma speaker ambiri akuluakulu amataya mphamvu zawo zoyankhira pafupipafupi pofuna kufunafuna mphamvu yapamwamba ya mawu (kusunga ndalama), ndi ma frequency osewerera osachepera 40Hz (ma frequency osewerera otsika, zofunikira za mphamvu ya amplifier ndi mphamvu yapamwamba yamagetsi, komanso mtengo wake ndi wokwera), zomwe sizingakwaniritse miyezo yogwiritsira ntchito zisudzo zapakhomo.

Choncho, posankha wokamba nkhani, ndikofunikira kusankha wokamba nkhani woyenera kutengera zosowa zenizeni za munthu komanso momwe zinthu zilili.

Ubale pakati pa kukula kwa sipika ndi mtundu wa mawu ndi wogwirizana kwambiri.

Lipenga likakula, malo ake okhala ndi diaphragm amakula, zomwe zimatha kufalitsa mafunde a mawu bwino ndikupangitsa kuti phokoso likhale lalikulu komanso lofewa. Lipenga laling'ono, kumbali ina, limapanga phokoso lakuthwa chifukwa malo okhala ndi diaphragm ndi ochepa ndipo mphamvu yofalitsa siili yabwino ngati lipenga lalikulu, zomwe zimapangitsa kuti zikhale zovuta kupanga phokoso lofewa.

Kukula kwa sipika kumakhudzanso momwe mawu amayankhira pafupipafupi. Kawirikawiri, sipika zazikulu zimakhala ndi mphamvu zabwino zotulutsa mawu ndipo zimatha kupanga mphamvu zochepa, pomwe sipika zazing'ono zimagwira ntchito bwino m'malo okwera kwambiri, zomwe zimapangitsa kuti mawu azimveka bwino kwambiri.

Komabe, posankha cholankhulira, kukula si chinthu chokhacho choyenera kuganizira. Ndikofunikiranso kuganizira mozama magawo ena oyambira a zida zamawu, monga mphamvu, kuchuluka kwa mayankho, impedance, ndi zina zotero, kuti magwiridwe antchito a cholankhulira akhale abwino kwambiri.
