Headphone mkuzamawu ndi manja anu mphindi 15

Lililonse kuyambira wokonda opanda zingwe pambuyo zatsopano woyamba bwino, kumverera kukoma kwa kunkhondo, amafuna kuyesetsa kuchita chinachake tsopano. Osati chidole, koma kwenikweni ntchito chinthu zonse. Kuchita izi, mwangwiro abwino amamwa yosavuta headphone mkuzamawu, lomwe ndi manja ya luso akhoza anasonkhana mu maminiti pang'ono chabe.

Kodi ndigwiritsa ntchito? Choyamba, chifukwa cholinga chake, ndiko kuti azimveka chizindikiro kwa kamvekedwe kapena preamplifier, ndiko kumene chizindikiro zomvetsera ndi ofooka kwambiri moti n'zosatheka kugwirizana Zomverera. Pankhaniyi, mukhoza kupanga headphone mkuzamawu ndi manja anu.

Kachiwiri, m'pofunika monga chida zina. Zam'manja headphone mkuzamawu ntchito kwambiri chifukwa madera kuyezetsa. Chifukwa nthawi zambiri pali kufunika kupeza malo kuswa circuitry yatsopano imene anasonkhana, koma sakufuna kugwira ntchito. Mwachitsanzo, mwachita chomwecho headphone mkuzamawu ndi manja anu. Adzathandiza ndi kufunafuna zimayambitsa vuto la. Ndi izo, inu mukhoza mofulumira kwambiri kupeza mfundo zomwe mbendera kusiyiratu. Nthawi izi zimachitika chifukwa cha asatipusitsenso ndi: zoipa soldered gawo, wolakwika capacitor, etc. Zowoneka kapena ndi Tester ndi chifukwa kungakhale kovuta.

Kupanga headphone mkuzamawu ndi manja anu basi chifukwa rekodi dera tichipeza zigawo zisanu zokha. Bukuli lili pa Chip TDA7050, zomwe ndalama 30-80 rubles. Koma ine ndikuganiza kuti wambiri wanu pakompyuta zigawo zikuluzikulu, amene nthawi zonse zilipo kwa aliyense wachangu Pankhaniyi, pali Chip amenewa. Amagwiritsidwa ntchito kawirikawiri mu osewera makaseti ndi zina phokoso kubereka zipangizo yosavuta.

Pa Chip womwewo ukhoza kukhala ndi sitiriyo headphone mkuzamawu ndi manja anu. Adzakula kuwonjezera awiri capacitor kumalo ozizira pa linanena bungwe (akhoza kukhala munthu wamba), ndipo athandizira buku ulamuliro zikhoza kupangidwa kuchokera wapawiri variable resistor.

Obweretsa Chip ndi mkuzamawu mphamvu mu mulingo nyumba (DIP8). Ntchito voteji wa volts 1.6 kuti 6. Izo amadya kwambiri mphamvu. linanena bungwe mphamvu zimadalira kotunga voteji. Mu chimake sitiriyo pansi pa katundu wa 32 ohms ndi voteji wa volts atatu pa linanena bungwe inu kutenga 130 milliwatts pa njira. Pamene olumikizidwa ku mlatho dera mu Pokhala mphamvu rekodi ndi kawiri. Linanena bungwe dera amatetezekanso dera yochepa.

Chojambula chithunzi anapatsidwa Chithunzi 1. chizindikiro athandizira umagwiritsidwa ntchito malo 1 ndi 3 ndi Zomverera 32 ohms olumikiza malo 7 ndi 8. Malinga ndi specifications mu mode kulithetsa, katundu sayenera zosakwana 32 ohms. Kutsegula kotunga voteji olumikiza basi capacitors C1 ndi C2, 100, ndipo 0,1 microfarads, motero. Resistor R1 - 22 ohms. Chabwino, mwinamwake, ndi zonse kufotokoza chitsanzo chathu choyamba.

Chiwembu yachiwiri Chithunzi 3 kawirikawiri amagwiritsidwa ntchito yaing'ono-kakulidwe zipangizo prefabrication. Kuti izo pang'ono kovuta. Chiwembu zikusonyeza mfundo zonse zofunika. Chithunzi 2 - chiwembu chomwecho kulumikiza okamba. Monga mukuonera, kusiyana ndi yaing'ono. The dera okamba capacitors kumalo ozizira ntchito iliyonse njira linanena bungwe, ndipo headphone - ataima capacitor wamba pa mfundo kugwirizana kwa dera zikusungira iwo.
