Headphone gudzazwi nemaoko enyu mumaminitsi 15

Ose kutanga Wireless Zvokutopenga mushure kuedza vakabudirira rokutanga, kunzwa kutapira okukunda ake, anoda kuedza kuita chinhu zvino. Kwete chitoyi, asi chaizvoizvo kushanda zvizere chinhu. Kuti aite izvi, zvakakwana yakakodzera mukaravhani nyore Headphone gudzazwi, riri maoko unyanzvi kunogona vakaungana mumaminitsi mashomanana.

Apo Ndinogona kushandisa? Chokutanga, nokuti chinangwa chahwo, kureva kuti kutsigira chiratidzo kubva matauriro kana preamplifier, kuti ndipo okuteerera chiratidzo anyanyopera simba, uye hazvibviri dzaiitirwa pamahedhifoni. Muchiitiko chino, unogona kugadzira Headphone gudzazwi nemaoko enyu.

Chechipiri, rinobatsirawo sezvi- chokushandisa. Portable Headphone gudzazwi rakanyatsojeka kushanda kunovhenekwa matunhu. Nekuti kazhinji pane kudiwa kuwana nzvimbo kuputsa hushande itsva kuti iwe ndaitora, asi iye asingadi kushanda. Somuenzaniso, maita chete Headphone gudzazwi nemaoko enyu. Achakubatsira ari kutsvaka zvinokonzera iri mhosva. With izvozvo, unogona kukurumidza kwazvo kuwana pana iyo chiratidzo nokupera. Zvinonzi Kazhinji ichi zvinoitika pamusana kunyengedzazve: zvakaipa soldered chikamu, vainyeperwa capacitor, etc. Nemaziso kana aine tester chikonzero inogona kunetsa kuwana.

Ita Headphone gudzazwi namaoko enyu nokuti monkey redunhu rinoumbwa yenhengo shanu chete. Zvinonzi inobva Chip TDA7050, izvo tinorasikirwa 30-80 rubles. Asi ndinofunga kuti mune Holdings dzenyu zvemagetsi zvinoriumba, idzo nguva dzose kuwanikwa chero chido iyi, pachine Chip yakadaro. It rinowanzoshandiswa kukaseti vatambi uye mamwe kurira rinozvibereka mano nyore.

Musi iwoyo Chip zvinogona kuitwa uye redhiyo Headphone gudzazwi nemaoko enyu. It vachafanira kuwedzera zviviri polar capacitor pamusoro goho (anogona kuva mumwe nevakawanda), uye mazano vhoriyamu kuzvidzora chinogona kuitwa kubva hunyambiri shanduka resistor.

Munotapira Chip ndiwo simba gudzazwi mune mwero kukura pekugara (DIP8). Kushanda voltage pamusoro 1,6 kusvika 6 volts. It unopisa yakawanda simba. goho simba kunobva romugove voltage. In musimboti redhiyo pasi mutoro 32 ohms uye voltage pamusoro volts matatu ari goho masvika anenge 130 milliwatts por mugero. Kana zvakabatana muna bhiriji mudunhu pachake monkey vanokwanisa kaviri. Output redunhu uyu anodzivirirwa remudunhu pfupi.

Schematic dhayagiramu hwakapiwa Figure 1. chiyamuro chiratidzo rinoshandisirwa zviteshi 1 uye 3 uye pamahedhifoni 32 ohms vari chokuita zviteshi 7 uye 8. Maererano nokurondedzerwa ari bridged rudzi, mutoro haafaniri kuva asingasviki 32 ohms. Kuti vamugadzirire voltage wedzerai chokuita kuti bhazi capacitors C1 uye C2, 100, uye 0.1 microfarads, ukuwo. Resistor R1 - 22 ohms. Zvakanaka, zvichida, uye zvose tsananguro muenzaniso wedu wokutanga.

Zano Figure 3 wechipiri rinowanzoshandiswa duku kadikidiki mano prefabrication. Kuti izvozvo zvishoma zvikuru. The zano kunoratidza ose anodiwa mashoko. Figure 2 - zvakafanana zano kubatanidza nevakurukuri. Sezvaunogona kuona, musiyano ishoma. The redunhu vakurukuri polar capacitors zvinoshandiswa neimwe goho gwara, uye Headphone - vakamira vanhuwo capacitor panguva kubatana womuratidza redunhu redzimba pavo.
