nkhani

Bokosi loyang'anira ma audio ndi gawo lofunikira pazida zomvera monga okamba ndi ma amplifiers.Itha kulimbitsa, kusefa, ndi kukulitsa ma siginecha amagetsi kuti ipereke zinthu zofunikira zamagetsi pakufalitsa nyimbo.Komabe, kwa anthu ambiri, kapangidwe kake ndi zigawo za audio circuit board zimakhalabe chinsinsi.Ndiye, ndi zinthu ziti zamagetsi zomwe gulu lozungulira la audio limapangidwa?Pansipa, tikuwonetsa m'modzim'modzi.

Wotsutsa

Chotsutsa ndi chigawo chomwe ntchito yake ndikuletsa kutuluka kwaposachedwa kapena kusintha kukula kwaposachedwa mudera, zomwe ndizofunikira kwambiri pakuwongolera kuchuluka kwa ma audio amplifier.Pali mitundu yambiri ya resistors mu matabwa audio dera, kuphatikizapo resistors wamba, resistors variable, potentiometers, etc. kukana kwawo makhalidwe ndi mphamvu ndi osiyana ndipo ayenera kukhazikitsidwa moyenera malinga ndi zosowa zosiyanasiyana.

Capacitor

Ma capacitor ndi chinthu china chofala chomwe chimasunga magetsi amagetsi ndikusefa kutuluka kwa magetsi mudera.The capacitors mu matabwa audio dera zambiri zotayidwa electrolytic capacitors, ceramic capacitors, poliyesitala filimu capacitors, etc. Mitundu yosiyanasiyana ya capacitors ndi makhalidwe osiyana ndipo ayenera kusankhidwa malinga ndi zosowa za dera audio.

Transistors ndi diode

Transistor ndi gawo la semiconductor lomwe ntchito yake ndikukulitsa zamakono, kuwongolera pakali pano, ndikuphatikiza ndi zigawo zina kuti apange dera linalake.M'mabwalo omvera, ma triodes amagwiritsidwa ntchito pamagetsi amplifier mphamvu, ma frequency ophatikizira osakaniza, ndi zina zambiri. Ma diode amagwiritsidwa ntchito posefera magetsi, kuzindikira ndi zina.

Transistor

Transistor ndi gawo lovuta la semiconductor lomwe ntchito zake zikuphatikizapo kukulitsa zamakono, kulamulira zamakono, ndi kutembenuza panopa kukhala mphamvu zotulutsa mphamvu monga kuwala, phokoso, kutentha, ndi zina zotero. kuyendetsa mayendedwe, etc.

Chip IC

Chip IC ndi chipangizo chaching'ono chozikidwa paukadaulo wa semiconductor chomwe chimatha kuphatikiza mabwalo ndi ntchito zovuta.M'mabwalo omvera, tchipisi ta IC nthawi zambiri amagwiritsidwa ntchito m'magawo ogwirira ntchito monga zosakaniza, zokulitsa mphamvu, ndi ma processor azizindikiro kuti akwaniritse kuwongolera koyenera komanso kolondola komanso kukonza.

Inductor

Inductorndi gawo lomwe ntchito yake ndikusungira mphamvu zamagetsi mumagetsi, kulepheretsa kufalikira kwa ma frequency a radio, fyuluta ndi ma drive sign, etc. M'mabwalo omvera, ma inductors nthawi zambiri amagwiritsidwa ntchito mu amplifiers mphamvu, kusefa kwamagetsi, audio crossover audio, ndi zina.

Mingda ndi katswiri wa inductor yemwe ali ndi zaka 17.Mutha kufunsa Mingda za chidziwitso chilichonse cha inductor.

Zomwe zili pamwambazi ndizozikuluzikulu zamagetsi zomwe zimapanga gulu la audio circuit.Amagwira ntchito yofunika kwambiri pamayendedwe amawu.Kwa abwenzi omwe amagwiritsa ntchito zida zomvera, ngakhale kuti palibe chifukwa chomvetsetsa tsatanetsatane wa zigawozi, kumvetsetsa makhalidwe awo oyambirira ndi ntchito ndizothandiza kwambiri kumvetsetsa mozama mfundo yogwiritsira ntchito zida zomvera.
