Indlela yokwenza amplifier ezikhulumini ngezandla zabo

Yiqiniso, akuwona wonke umsebenzisi PC uyazinaka izinga umsindo ozwakala kusukela izipikha ezixhunywe engumngane digital. Waneliseke Iningi ngomsindo onokuthula engahlanzekile kakhulu futhi eliphezulu ukuthi ungaveza amadivayisi zamanani aphansi. Njengoba sazi ukuthi imakethe eliphezulu imishini yokukhulisa umsindo lukhula like amakhowe emva kwemvula, abantu abaningi bakhetha nje kuphela onamandla, besiyoba sikhulu, kodwa futhi umsindo wekhwalithi ephezulu. Indlela yokwenza amplifier for izikhulumi ngezandla zabo?

Kuyinto engenakwenzeka ukucabanga yiluphi uhlelo umsindo ngaphandle le ngxenye. Akukhona ezishibhile, ngakho nalabo abangakwazi ukuthenga izimpahla ezibizayo ezitolo ezikhethekile, qiniseka ukuqoqa amplifier ekhaya ngoba isikhulumi ngezandla zakho. Lesi seluleko Uzokhanga kubo bonke labo design eletha eziningi ukuzijabulisa. Phela, wenza siqu sakhe kuyoba okuningi eqolo ngaphezu kwanoma ejwayelekile esitolo-uthenge futhi abavamile.

Kanjani ukuze ahlangane amplifier ezikhulumini futhi kungakanani ngempela?

Ngokwemvelo, kudingeka ezinye amakhono nolwazi thina ngasohlangothini electronics. Amandla la amadivaysi zingase zihluke. Ngakho-ke, ngaphambi kokuba ukuklama-amplifier ezikhulumini, kudingeka unqume ukuthi ngayiphi injongo udinga lo mkhiqizo nokuthi izosetshenziswa inqubo. Endabeni umsindo amplifier abazinikezele subwoofer noma ama-headphone uzodinga ezithile imininingwane ikhadi umsindo - kuhluke ngokuphelele.

Ukuze amplifier kuya izikhulumi bebodwa, idinga isikimu ezinhle (lena akuyona inkinga njengoba enjalo kwi-inthanethi eziningi, udinga kuphela ukukhetha ofanele kakhulu kuwe), kanye namakhono adingekayo ukuze solder ku imininingwane isikimu abakhethiwe. Ngokuyisisekelo umzimba ukuthi kufanelekile ukuba nohlobo kanye nosayizi, iphrintwe wesifunda ibhodi, isihlungi esisebenzayo, Umlawuli IC, op amp, i-DAC, kanye umamukeli digital.

Ngemva kwako konke udinga uthenge, ungakwazi uqale umsebenzi. Kungcono ukuthenga izingxenye ezibizayo yangempela ngoba nge ezishibhile mayelana ikhwalithi yomsindo yokukhuluma akukwazi. Ngemva amplifier ezikhulumini wenze ngokwakho umsindo kwakuhlanzekile futhi akunakuqhathaniswa.

Kufanele uqale ne ukulungiswa isiliphu wesifunda ibhodi. Kwenze kungenzeka, futhi izandla zakho, kodwa kungcono ukuthenga kanye nezinye izinto, isb. Ngo. Lena ngenye yezingxenye eyinhloko amplifier yethu. Ungase futhi oda ke kulabo abamazi enkulu ekwakhekeni mishini.

Uma zonke izingxenye zilungele, ukuqoqa zesikhulisa Isilawuli akuthathi kakhulu. Into esemqoka - ukuba nizifeze zonke njalo futhi ngokuvumelana isikimu sakho.

Mhlawumbe ngemuva kwamahora ambalwa zahripit isikhulumi kusho akwanele wamanje kanye wenza iphutha, bajoyine umqhele yesibili ochungechungeni, kunokuba ukufakwa oqondile. Kulokhu, lo voltage uhlala ingashintshiwe kanye zamanje iyakhula.

Kahle wesifunda ababebuthene akufanele enze ama-cod, iyiphi hum noma umsindo. Uma kukhona kulokhu okungenhla ukuthi lukhona, kubalulekile ukuhlola wesifunda. Mhlawumbe awazi ukuthi soldered phambili ezinye ezimbi.

Uma zonke izingxenye yehhashi egibele, zonke izingxenye soldered, futhi izinga akuyona ungaqiniseki, isivele kungenzeka ukuxhuma amplifier yakho ukuze umsakazo ngomumo. Ngisho naphezu kweqiniso lokuthi kuba ingxenye sasivumela ebalulekile ohlelweni okulalelwayo, zonke ezinye izingxenye kumele kuhambisane ezingeni eliphezulu. Kuphela kulesi simo uzothola izinga lonke uhlelo enamandla futhi umsindo bebonke.

Futhi, ekugcineni, ngomumo ukuba kuhlanganiswe kule scheme izindlu bese ubeka amplifier ezikhulumini ngendlela othanda ngayo.
