Hav! txhua tus Kuv lub npe yog Steve.

Hnub no kuv yuav qhia koj Yuav Ua Li Cas 100 Watt Portable Amplifier hauv Txoj Kev Yooj Yim heev

Nyem qhov no mus Saib Cov Video

Cia Pib

Kauj ruam 1: Nta

Lub Hwj Huam Tso Tawm

100 Watt x 1 @ 4Ohms

Lub Hwj Chim Fais Fab

16 - 35V DC

Built-in Kev Tiv Thaiv

• QHOV CHAW UA HAUJ LWM HAUJLWM VOLTAGE RANGE (± 40V)

• Soldering Iron -
• Yooj Yim Caj Npab -

Aliexpress

• 24V SMPS -
• Soldering Hlau -
• Yooj Yim Caj Dab -

Kauj Ruam 3: Daim duab Circuit Court

Koj tuaj yeem pom daim duab qhia chaw kom yooj yim dua

Kauj Ruam 4: TDA7294

Piav qhia txog TDA7492

TDA7294 yog ib qho kev sib txuas ua ke nyob rau hauv Multiwatt15 pob, npaj rau siv ua suab AB chav ua suab nrov hauv Hi-Fi daim ntawv thov (Lub Tsev Hauv Tsev, lub suab nrov siv lub suab, Topclass TV). Ua tsaug rau qhov dav hluav taws xob ntau thiab kom muaj peev xwm tshaj tawm tam sim no nws muaj peev xwm muab lub zog siab tshaj plaws rau hauv ob qho 4Ω thiab 8Ω thauj khoom txawm hais tias muaj cov cai tswj tsis zoo, nrog Cov Khoom Siv Hluav Taws Xob Siab Siab. Ua hauv kev hloov pauv ua haujlwm nrog tig rau ncua sijhawm ua kom yooj yim kev ua haujlwm nyob deb kom tsis txhob hloov lub suab nrov nrov.

Kauj ruam 5: Sponsor

Kab lus hnub no tau txhawb nqa los ntawm lcsc.com

Lawv yog Cov Khoom Siv Hluav Taws Xob Loj Tshaj Plaws Los Ntawm Tuam Tshoj Npaj Yuav Nkoj Hauv 4 Teev Sijhawm thiab lawv xa thoob Ntiaj Teb

Kauj Ruam 6: PCB Board Designing

Kuv Siv EasyEDA Los Tsim Kuv Li PCB Siv Daim Duab Duab Circuit muab los ntawm STMicroelectronics thiab nws coj kuv txog 2 teev los tsim

Koj tuaj yeem pom kuv tau siv XT30 rau cov lus hais tawm kom yooj yim ntsaws thiab ua si

thiab rau lub hwj chim tawm tswv yim, Kuv tau siv 3 Cov Ntawv Txuas Txuas

Koj tuaj yeem rub tawm Gerber Cov Ntaub Ntawv

Gerber & Circuit Diagram -

Kauj Ruam 7: Txiav txim rau PCB

Nowa Hnub nws tau yooj yim heev los xaj PCBs thiab nws tsis raug nqi koj ntau, Yog lawm koj yooj yim ua qhov no hauv Pawg Thawj Coj tab sis PCB Zoo li txoj hauv kev zoo dua li Perf Board thiab nyab xeeb rau ua haujlwm Yog li koj tuaj yeem tso haujlwm me me thiab nyiaj txiag kom tau txais Kev Ntsuam Xyuas Zoo

Txog Qhov Haujlwm no, Kuv tau siv ALLPCB Kev Pabcuam rau Kev Tsim Kuv Cov PCB thiab nws siv sijhawm li 24 Teev los Tsim Kuv Li PCBs thiab hauv 7 Hnub Lawv Xa Nws Mus Rau Kuv Qhov Rooj Kauj Ruam

Thiab Qhov Zoo Tsuas Yog Zoo Tshaj

Kauj ruam 8: Soldering

Kuv tau sau tag nrho cov khoom siv thiab siv tag nrho cov Kev Tiv Thaiv ua ntej, thiab tom qab ntawd muab cov Capacitors Raws Li Daim Duab Circuit Court thiab siv Cutter los txiav txhua ceg ntxiv

Thiab tom qab ntawd kuv tau Soldered Main Ic TDA7294

Tom qab ntawd, Kuv tau Soldered lub 3.5mm Cov Phiaj Xwm Txuas thiab XT30 Txuas thiab nws coj kuv li 30 feeb

Kauj Ruam 9: Tshav Kub Kub

Kuv tau siv Qhov Loj Qhov Tshav Kub Kub Shink rau Tshav Kub Kub dissipation nws yog qhov tsim nyog yuav tsum tau siv Cov Tshav Kub Kub Tsuag Yog Tsis Li Koj Yuav Hlawv Cov Chip

Thiab nws yog ib qho tseem ceeb heev uas yuav tsum tau siv cov khoom ua kom sov zoo kom sov kom sov zoo

Kuv tau thov me ntsis kom muaj cov cua sov sib xyaw rau TDA7294 IC thiab ua kom nruj nrog lub rhaub dej kub

Kauj ruam 10: Sawv Tawm

Tom qab lub rhaub dej kub, Kuv siv 4 sawv tawm los muab nws qee qhov kev tshem tawm

Kauj Ruam 11: Cov Khoom Siv Hluav Taws Xob

Kuv siv 2 SMPS txhua 24V @ 6 Amps muab tag nrho 48V @ 6 Amps

SMPS txuas nrog hauv Series "Nws hu ua Daul Power Supply"

+24 0 -24 V

Koj tseem tuaj yeem siv Transformer Raws Lub Hwj Huam Muab Khoom tsis muaj teeb meem nrog qhov ntawd

Kauj Ruam 12: Teeb thiab Txaus Siab

Ua ntej kuv tau txuas tus Hais Lus nrog XT30 Txuas

Qhov thib ob Kuv tau txuas nrog 3 Lub Hwj Huam Hluav Taws Xob ntawm Bullet Connector

• Liab - Zoo
• Ntsuab - Hauv av
• Dub - Tsis zoo

Thib peb Kuv tau txuas lub Audio Input cable thiab txuas nws mus rau Audio source
