Momwe mungathanirane ndi mawu otuluka kuchokera kwa okamba

⭐ ⭐ ⭐ ⭐ ⭐ Madalaivala ambiri nthawi zambiri amayang'anizana ndi funso la momwe angachotsere kusokoneza (kuimba mluzu, phokoso lochokera kwa okamba), zomwe nthawi zambiri zimachitika mumayendedwe a galimoto.

Vutoli limatha kuchitika mumayendedwe aliwonse a stereo, mosasamala kanthu kuti zida zake ndi zamtundu wanji, kaya ndi bajeti yaku China, bajeti yapakatikati kapena premium. Choncho, tikukulimbikitsani kuti muwerenge nkhaniyi kuti mufufuze molondola za zomwe zingayambitse phokoso loipa komanso njira zothetsera.

Malamulo oyambira oyika:

• Lamulo loyamba. Kuti ma audio agalimoto amveke bwino momwe angathere, ndikofunikira kugula zingwe zamagetsi zapamwamba kwambiri ndi mawaya a speaker / interconnect. Ndi ndalama zochepa, cholinga chachikulu chiyenera kukhala pa ma interconnect cable connectors. Panthawi yogwira ntchito yagalimoto, makina ake amagetsi amapanga minda yamagetsi yamagetsi osiyanasiyana, kuchuluka, mphamvu komanso ma frequency. Ndiwo omwe amayambitsa phokoso lomwe limadutsa zishango zosapangidwa bwino za zingwe za RCA.
• Lamulo lachiwiri. Zingwe zolumikizira ziyenera kuyikidwa m'njira yoti zikhale kutali kwambiri ndi zinthu zina zamawaya amagetsi agalimoto. Komanso sayenera kukhala pafupi ndi mawaya amagetsi opita ku makina omvera. Zindikirani kuti kulowera kwaphokoso kudzachepetsedwa ngati mphambano ya mawaya a sipikala ndi zingwe zamphamvu ziyikidwa pa ngodya yoyenera.

• Lamulo lachitatu. Osagula zingwe za RCA zomwe ndizokulirapo. Utali waufupi, m'pamenenso umakhala wocheperako kupanga chojambula chamagetsi.
• Lamulo lachinayi. Kuyika kokonzedwa bwino kwa makina omvera agalimoto kumapereka maziko azinthu zonse zadongosolo panthawi imodzi yokha.Kupanda kutero, zigawo zikakhazikika m'malo osankhidwa mwachisawawa, zomwe zimatchedwa "ground loops" zimawonekera, zomwe ndizomwe zimayambitsa. kusokoneza poyimba nyimbo.

Mwatsatanetsatane za momwe tingagwirizanitse bwino amplifier, tafufuza "pano".

Ground Loops ndi Kuganizira Kuyika

Lamulo lachinayi pamwambapa likunena kuti chimodzi mwa zifukwa zomwe zimakhala phokoso lachilendo mwa okamba ndi kukhalapo kwa "loops zapansi". Kukhalapo kwawo m'malo angapo kumapangitsa kuti pakhale ma voltages osiyanasiyana m'malo ena agalimoto. Izi zimabweretsa kuoneka kwa phokoso lowonjezera.

Thupi lagalimoto, kwenikweni, ndi chitsulo chachikulu, chomwe chimagwiritsidwa ntchito ngati "nthaka" yamagetsi amagetsi. Kukaniza kwake kwamagetsi ndikochepa, koma kulipo. Zilibe mphamvu pakugwira ntchito kwa zipangizo zamagetsi zoyendetsa zokha, zomwe sizinganenedwe ponena za phokoso. Popeza pali ma voltages a kuthekera kosiyanasiyana pakati pa nsonga za thupi, ma microcurrents amawuka, komwe kudzazidwa kwa wokamba nkhani kumakhala kovuta kwambiri.

Pofuna kupewa phokoso la phokoso, muyenera kugwiritsa ntchito malamulo awa:

• Dongosolo lokhazikika limapangidwa kuti zigawo zonse za "misa" zigwirizane pamfundo imodzi. Yankho labwino kwambiri ndikugwiritsa ntchito chomaliza cha batri kapena malo omwe ali pathupi pomwe malo oyipa amagetsi amakhazikika. Posankha mawaya, kutsindika kuyenera kuyikidwa pa mawaya apamwamba kwambiri, omwe amapangidwa pogwiritsa ntchito mkuwa wopanda oxygen. Malo okhudzana ndi chingwe ndi thupi ayenera kutsukidwa kuchokera ku utoto, dothi ndi dzimbiri. Ndi bwino kuthetsa chingwe ndi crimping kapena soldering wapadera nsonga mu mawonekedwe a mphete ya awiri oyenera. Mukamapanga mawaya apansi ndi mphamvu, gulani zolumikizira ndi zomangira zagolide;

• Zigawo zachitsulo zamawu omvera siziyenera kukhudzana ndi thupi lagalimoto kulikonse. Kupanda kutero, pakuyika ma acoustics ndi manja anu, mwiniwake wagalimoto amakwiyitsa mawonekedwe a loop pansi, ndi zotsatira zake zonse;

• Mawaya onse akalumikizidwa ndi wailesi ndi awiri awiri a okamba, yang'anani momwe amagwirira ntchito. Yatsani makina a stereo ndikuyesa ndi mlongoti wosalumikizidwa. Moyenera, pasakhale phokoso;
• Kenako, muyenera kuletsa stereo pansi pa thupi. Ngati zonse zachitika molondola, phokoso lidzatha, wailesi idzazimitsa. Uwu ndi umboni wachindunji wa kukhalapo kwa malo amodzi apansi komanso kusowa kwa malupu. Palibe amene angapereke chitsimikizo cha 90% cha kusakhala kwa phokoso, komabe, mudzadziteteza ndi XNUMX peresenti.
  
  Zimachitikanso kuti pakuyika makina omvera, sikutheka kuyika zinthu zonse pamalo amodzi. Njira yothetsera vutoli ndikusankha mfundo ina yolumikizira misa. Mlanduwu umagwira ntchito pokhapokha kusiyana kwamagetsi pakati pa maziko ndi mfundo zowonjezera pansi sikudutsa 0.2V. Kapenanso, amplifier imakhazikika kumbuyo kwa galimoto, ndipo chofanana, wailesi ndi crossover zili pagawo la thupi pakati pa injini ndi chipinda chokwera.

Ndikufunanso kuzindikira kuti fyuluta yabwino mu dongosolo ndi kukhalapo kwa capacitor.

Kodi kuchotsa phokoso?

Tinaganizira zomwe zimayambitsa phokoso ndi malangizo pa kukhazikitsa bwino mawaya ndi zipangizo. Taganiziraninso njira zomwe ziyenera kutsatiridwa pamene, mwachitsanzo, injini ikupita patsogolo, zomwe zimachititsa kuti phokoso likhale losokoneza?

Mayankho akufotokozedwa pansipa:

• Chotsani mutu wa mutu ku makina omvera.Ngati palibe phokoso, chomalizacho chiyenera kukhazikika pamtunda wofanana pa thupi, womwe umagwiritsidwa ntchito ndi zigawo zina zamawu.

• Phokoso likapitilirabe, ndipo ma cell akhazikika m'malo osiyanasiyana, tengani multimeter ndikuwunika mphamvu yamagetsi pakati pazigawo zonse ndi batire yokhazikika. Ngati mupeza kusiyana pazotsatira, muyenera kufananiza voteji pakati pa zigawo zonse. Yankho labwino pankhaniyi ndikuyika zigawo zonse pamalo amodzi, kapena kupeza malo ena pomwe magetsi pakati pa zigawozo sangasiyane. Payenera kukhala mulingo wocheperako wamagetsi pakati pa zotsekera zonse mudongosolo. Kuwerenga kumawunikiridwa poyesa kusiyana kwa voteji pakati pa zishango (zoluka) zopezeka mu zingwe za RCA pakuphatikiza kulikonse.
• Ngati mutapeza zotsatira zochepa kwambiri pa kusiyana kwa magetsi panthawi yoyesera ndi ma multimeter, phokoso lochokera ku zosokoneza lingawonekere pazifukwa zina zingapo: Choyamba mwa izi chikhoza kukhala kuyandikira kwa mawaya a RCA ku zingwe zamagetsi. chifukwa chachiwiri kungakhale kufanana ndi pafupi malo mawaya lamayimbidwe kwa chingwe mphamvu, kapena sanali kutsatira ngodya lamanja la mphambano. Komanso onetsetsani kuti amplifier kesi ndi insulated bwino. Kuphatikiza apo, mlongoti wosakhazikika bwino ukhoza kupanga malupu ndikuyambitsa kusokoneza. Chifukwa chomaliza chingakhale kukhudzana kwa waya wamayimbidwe ndi thupi lagalimoto.
  

  

  anapezazo

Kukachitika kuti kuyimba mluzu kapena mavuto owonjezera awonedwa pakugwira ntchito kwa okamba, onetsetsani kuti mwayang'ana mawonekedwe a okamba mgalimoto yanu. Kulephera kutsatira malangizowo, kugwiritsa ntchito zinthu zotsika kwambiri kapena zowonongeka kumatsimikiziridwa kuti kungayambitse mavuto akulu pakugwira ntchito kwa stereo.

Tachita khama kwambiri popanga nkhaniyi, kuyesera kuilemba m'chinenero chosavuta komanso chomveka. Koma zili ndi inu kusankha ngati tinachita kapena ayi. Ngati mudakali ndi mafunso, pangani mutu pa "Forum", ife ndi gulu lathu laubwenzi tidzakambirana mwatsatanetsatane ndikupeza yankho labwino kwambiri.
