Kusefa kwa bandi
Chenjerani! Choyimitsira kutentha chokhala ndi guluu wa 3M chiyenera kuikidwa pa chip palokha, onetsani chithunzithunzi chofotokozera, kutentha kwambiri kumamatira kumapangitsanso kutentha kwabwinoko. Mtundu wamilandu uyenera kusonkhanitsa mlanduwo, ndipo mtunduwo umabwera ndi screwdriver.
Izi ndizodzaza ndi zida, makamaka magwiridwe antchito apamwamba, okwera mtengo, makamaka nyimbo za HIFI kuti zipereke amplifier yamphamvu kwambiri.
TPA3116D2 ndi Class D magetsi amplifier IC yoyambitsidwa ndi kampani ya TI, yokhala ndi magawo apamwamba kwambiri. Ma frequency osinthika amatha kufika mpaka 1.2MHZ, ndipo kupotoza kwamphamvu kwambiri kumakhala kotsika 0.1%.
Ndi AUX ndi Bluetooth njira ziwiri zolowera magwero amawu, ziwiri mwa imodzi;
Potentiometer kusintha voliyumu, ndi switch, yosavuta kuwongolera voliyumu, yoyenera kwambiri kwa olankhula DIY.
Ndi fyuluta inductance, phokoso limakhala lozungulira komanso lomveka bwino.
Copper DC cholumikizira, cholumikizira mpanda, kupirira pakali pano, palibe kutentha, palibe kuwonongeka kwa waya, mawaya abwino, osavuta kuyenda pafupipafupi.
Waya wamutu wa DC ukhoza kukhala wogwirizana ndi mawonekedwe amagetsi opangira izi, ngakhale mulibe adapter yamutu ya DC kapena batire, imatha kulumikizidwa mosavuta.
5.0 Bluetooth Baibulo, apamwamba kufala dzuwa, yaitali kufala mtunda.
Chidziwitso chogwiritsa ntchito: Chosinthira magetsi pa bolodi ndi chosinthira choyimilira, ndipo makinawo amakhala otsika mphamvu yoyimirira atazimitsa chosinthira. Kuti muzimitse mphamvu zonse kapena ngati sizikugwiritsidwa ntchito kwa nthawi yayitali, pulagi ya DC pamakina imatha kutulutsidwa.

Yankho ku mafunso:

1. Kodi kusankha magetsi?

Kupereka mphamvu kwa bolodi ndikofunikira. Kukwera kwa voliyumu, kukulirapo kwapano, komanso mphamvu yotulutsa yokwanira, ngati muli ndi 12V 1A yokha, mutha kubweretsa olankhula 3-4 inchi. Ngati muli 19V 5A kapena kuposa, palibe vuto ndi mainchesi 8-10, ndipo magetsi ayenera kukhala ofunika kwambiri. Ngati voteji ndi yotsika kwambiri, kukweza kwa mawu ndikosavuta kupangitsa kusokoneza kwa mawu, ngati mphamvuyo ndi yaying'ono kwambiri kuti ibweretse wokamba nkhaniyo imakokera voteji pansi, ntchitoyo ndi yachilendo kapena khalidwe la phokoso ndilochepa.

Tikulimbikitsidwa kugwiritsa ntchito magetsi a 18V19V24V, omwe ali pamwamba pa 3A. Ngati muli ndi mphamvu ya 9V12V kapena 1A 2A yokha, itha kugwiritsidwanso ntchito koma mphamvuyo ndi yaying'ono, tcherani khutu ku voliyumu yayikulu mukamagwiritsa ntchito ikhoza kusokoneza phokoso.

2. Mungasankhe bwanji wokamba nkhani?

Nyanga zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala 8 ohms, sizingathe kusiyanitsa pakati pa polarity zabwino ndi zoipa, zotsatira zake ndi zofanana, 4 ohms ya nyanga ingagwiritsidwenso ntchito. Ngati mphamvu yanu ya nyanga ndi yaying'ono, ikhoza kukhala pakati pa 10W-30W ingagwiritsidwenso ntchito, magetsi operekera ndi ochepa kuti ateteze mokweza pambuyo powotcha lipenga, monga kusankha magetsi pansi pa 15V. Ngati muli nyanga ya 50W-200w, musadandaule za vuto la nyanga yoyaka, mutha kusankha magetsi a 12-24V, kukweza kwa voliyumu yosankhidwa, ndiye kumveka kwakukulu kapena mphamvu.

3. Mungasankhire bwanji Bluetooth kapena AUX audio input mode?

Yambani pa board amplifier yamagetsi, gwirizanitsani choyankhulira, tembenuzirani cholumikizira chamtundu wa buluu, tsegulani Zikhazikiko za foni -- Bluetooth - fufuzani "BT-WUZHI", kenako dinani kulumikiza, mutalumikizana bwino, padzakhala ding. dong mwachangu, pakadali pano pamayendedwe a Bluetooth, mutha kusewera nyimbo, mphamvu yotsatira idzalumikizidwa yokha ku foni.

Ngati mukufuna kugwiritsa ntchito mawu a AUX, mutha kuletsa kulumikizana kwa Bluetooth, padzakhalanso mawu omveka, plug mu chingwe chomvera kuti muyimbe nyimbo. MU mode AUX (LINE IN), Bluetooth imasinthidwa kukhala Bluetooth mode.

4. Phokoso laling'ono liri bwino, phokoso litatha, pali chodabwitsa cha mitambo yamtambo?
Phokosoli lasokonekera, chonde sinthani adaputala yamagetsi yokhala ndi mulingo wapamwamba kwambiri.

5. Phokoso laling'ono liri bwino, pamene phokoso likukulirakulira, pali chodabwitsa cha phokoso?
Mphamvu yolowera ndiyosakwanira, magetsiwo amazimitsa chitetezo nthawi ndi nthawi, chonde sinthani magetsi amphamvu kwambiri; Kapena mphamvuyo ndi yayikulu kwambiri, bolodi la amplifier lamagetsi limatenthedwa kwambiri, ndipo chitetezo chamafuta chimawonekera, kuchepetsa kugwiritsa ntchito mphamvu kapena kulimbitsa kutentha.
