Masiku anomachitidwe omvera,amplifiers mosakayikira ndi chimodzi mwa zigawo zofunika kwambiri.Sizimangokhudza ubwino wa phokoso, komanso zimatsimikizira ntchito yonse ndi zochitika za ogwiritsa ntchito.Nkhaniyi ifotokoza mfundo zazikuluzikulu zaamplifiers mphamvukuti zikuthandizeni kumvetsa chifukwa chake zinthu zimenezi zili zofunika kwambiri.
1. Kutulutsa mphamvu: Yendetsani mtima wa nyanga
Imodzi mwa ntchito zazikulu za amplifier ndi kupereka mphamvu zokwanira kuyendetsa wokamba nkhani.Kutulutsa kwamagetsi kumatsimikizira ngati makina omvera amatha kusunga mawu omveka bwino komanso osasokoneza pama voliyumu osiyanasiyana.Mphamvu yotulutsa mphamvu ya amplifier nthawi zambiri imawonetsedwa mu watts (W).Kusankha amplifier yoyenera kumafuna kulingalira mfundo zotsatirazi:
Mphamvu yovotera ya choyankhulira: Mphamvu ya chokulitsa iyenera kufanana ndi mphamvu ya woyankhulira.Mphamvu yocheperako ingayambitse mawu osakwanira komanso kusokoneza, pomwe mphamvu yochulukirapo imatha kuwononga wolankhula.
Kukula kwa zipinda ndi malo omveka bwino: M'zipinda zazikulu kapena malo osamveka bwino, ma amplifiers apamwamba amafunikira kuti mutsimikizire kumveka kofanana komanso komveka bwino.
Mtundu wa nyimbo komanso mayendedwe omvera: Ogwiritsa ntchito omwe amakonda kumvera nyimbo zamitundu yosiyanasiyana angafunike zokulitsa mphamvu kuti asunge tsatanetsatane komanso kusinthasintha kwa nyimbozo pama voliyumu apamwamba.
2. Kusokoneza: Wakupha wosawoneka wamtundu wamawu
Kusokoneza ndi chimodzi mwazizindikiro zofunika pakuwunika mtundu wa amplifiers mphamvu.Zimatanthawuza kusintha kulikonse kosafunikira mu siginecha yolowera panthawi yokulitsa.Pali makamaka mitundu iyi ya kupotoza:
Kusokonekera kwa Harmonic: Kuchulukirachulukira komwe kumapangidwa panthawi yokulitsa ma siginecha.Kusokoneza uku kungapangitse kuti phokoso likhale losakhala lachibadwa komanso kusokoneza khalidwe la mawu.
Kusokoneza kwapakati-modulation: ma frequency atsopano opangidwa pomwe ma siginecha amitundu yosiyanasiyana amasakanikirana mu amplifier, zomwe zimatha kubweretsa ma toni osafunikira mu siginecha yamawu.
Kusokoneza kwa Trans-conductance: Ubale wopanda mzere pakati pa kutulutsa kwa amplifier yamagetsi ndi chizindikiro cholowera, nthawi zambiri zimachitika pakudzaza.
Mapangidwe abwino kwambiri a amplifier amachepetsa kusokoneza uku ndikupereka mawu omveka bwino komanso achilengedwe.
3. Kuyankha pafupipafupi: Kubwezeretsa m'lifupi ndi kuya kwa mawu
Kuyankha pafupipafupi kumatanthawuza kuchuluka kwa ma frequency omwe chokulitsa mphamvu chimatha kukulitsa bwino, nthawi zambiri chimayesedwa mu Hertz (Hz).Chokulitsa choyenera chiyenera kupereka kukweza kosalala komanso kofanana pamawu onse (nthawi zambiri kuyambira 20Hz mpaka 20kHz).Kuchuluka kwa kuyankha pafupipafupi kumakhudza mwachindunji kubwezeretsa kwa mawu:
Kuyankha kwafupipafupi: kumakhudza kuya ndi mphamvu ya bass.Ma Amplifiers okhala ndi mayankho otsika kwambiri amatha kupereka zotsatira zolimba za bass.
Kuyankha kwapakati pafupipafupi: kumakhudza makamaka magwiridwe antchito a mawu ndi zida, ndipo ndiye gawo lofunika kwambiri lamawu.
Kuyankha pafupipafupi: Kumakhudza kumveka bwino komanso tsatanetsatane wa manotsi apamwamba, ndipo chokulitsa mphamvu chokhala ndi kuyankha kwapafupipafupi kungapangitse kuti mawuwo amveke bwino komanso owoneka bwino.
4. Chiŵerengero cha Signal to Noise (SNR): chitsimikizo cha khalidwe lomveka bwino
Signal to Noise Ratio ndi chizindikiro chomwe chimayesa chiŵerengero chapakati pa chizindikiro chothandiza ndi phokoso mu chizindikiro chotulutsa mphamvu ya amplifier ya mphamvu, yomwe nthawi zambiri imawonetsedwa mu decibel (dB).Chiŵerengero chapamwamba cha signal-to-noise chimatanthawuza kuti chokulitsa mphamvu chimapanga phokoso lochepa lakumbuyo pokulitsa chizindikiro, kuonetsetsa kuti mawu amveka bwino.Kusankha chokulitsa mphamvu chokhala ndi chiŵerengero chapamwamba cha ma signal-to-noise kungathe kuchepetsa kusokoneza kwa makutu ndikupereka chidziwitso chomvera kwambiri.
5. Mapangidwe ozungulira a amplifiers amphamvu: mwala wapangodya wa kutsimikiza kwa ntchito
Mapangidwe amkati amagetsi amplifier amakhudza mwachindunji magwiridwe ake komanso kumveka bwino.Pali mitundu ingapo yofananira yozungulira:
Kalasi A amplifier: Ndi mawu abwino kwambiri koma otsika kwambiri, ndiyoyenera makina omvera apamwamba omwe amatsata kumveka bwino kwambiri.
Amplifier ya Class B: Kuchita bwino kwambiri koma kupotoza kwakukulu, komwe kumagwiritsidwa ntchito kwambiri pakati mpaka pamawu otsika.
Class AB amplifier: Imaphatikiza zabwino zonse za Class A ndi Class B, zogwira mtima kwambiri komanso zomveka bwino, ndipo pakadali pano ndi kapangidwe kake kokulirapo.
Amplifier ya Class D: Yogwira ntchito bwino kwambiri komanso kukula kochepa, ndiyoyenera kunyamula zida ndi makina amakono a zisudzo zapanyumba.
Mapangidwe aliwonse ozungulira ali ndi zabwino ndi zovuta zake, ndipo kusankha mtundu wa amplifier womwe umagwirizana ndi zosowa zanu ndikofunikira.
6. Ntchito ndi mawonekedwe a amplifiers mphamvu: kukwaniritsa zosowa zosiyanasiyana
Ma amplifiers amakono samangofunika mawu omveka bwino, komanso amafunikira kuti apereke magwiridwe antchito olemera ndi mawonekedwe kuti agwirizane ndi zochitika zosiyanasiyana zogwiritsiridwa ntchito.Mwachitsanzo:
Malo angapo olowera, monga RCA, fiber optic, coaxial, HDMI, ndi zina zambiri, amathandizira kulumikizana kwa zida zosiyanasiyana zomvera.
Kulumikiza opanda zingwe: monga Bluetooth ndi Wi-Fi, osavuta kuphatikiza ndi zida zam'manja ndimachitidwe anzeru akunyumba.
Thandizo lamayendedwe angapo: oyeneramachitidwe owonetsera nyumba, kumapereka chidziwitso chozama kwambiri.
Kusankha amplifier yabwino kumafuna kulingalira mozama za zinthu monga kutulutsa mphamvu, kupotoza, kuyankha pafupipafupi, chiŵerengero cha ma signal-to-noise, kamangidwe ka dera, kagwiridwe ka ntchito, ndi malo olowera.Ndi njira iyi yokha yomwe tingathe kuwonetsetsa kuti makina omvera akuyenda bwino kwambiri komanso akugwiritsa ntchito makina omvera.Kaya ndinu okonda nyimbo kapena okonda zisudzo zapanyumba, kumvetsetsa ndi kulabadira zinthu zazikuluzikuluzi kukuthandizani kusankha chipangizo chokulitsa chomwe chimakuyenererani bwino, ndikupangitsa kumvetsera kulikonse kukhala kosangalatsa.
