DIY: Stereo Audio Amplifier 3.5mm
HTML-код
- Опубликовано: 10 сен 2024
- Build from scratch, speakers, resistor and capacitors from old analogue TV.
Mosfet Tip31c: bit.ly/tdjgdsa
Step down module: bit.ly/2Wffql4
Power jack: bit.ly/3a5hGTx
-Input 6V, use heat dissipator.
-1k resistor ,16V 100uf capacitor.
-Schematic at 2:15
-Sound is clear in highs and mediums, the bass is not very strong.
-Using step down converter to supply 3 Volts to the blue led.
-Simple to build, easy design, i´m happy with the final result.
-12 volts is the max power supply, 6V to 8V is recommended.
-Heat dissipator from PC motherboard.
-Tested also with 0514 transistor.

No voice. No bullshit . Just amazing sounds of equipments. Good job man.
-Links, music names and more infos in the description :)
-Most of the parts are from an old tv, i used the tip31c because i had a few to use (could use the transistor from the tv also), i wanted to build the easiest and most inexpensive (free) audio amp possible, even the case its from a not used part from one of my other projects, it was a fun project to do :)
Referencia do transistor

Sensational, dude. I watched a bunch of videos, and most of them were either unreliable or too complex for me. The sequence of your project is so logical and clear that it greatly increased some fundamentals that I didn't have yet. Thank you so much for your generosity.
thank you, glad you liked :)
Life hack: use a single 1k resistor in series with the LED instead of the seperate regulator.
This amp turned out really good
Dont know why but I find it so comical watching it sped up. Awesome work dude. 😁
Дешевле купить китайскую поделку, которая будет звучать лучше и выглядеть лучше. А если уж принципиально хочется сделать что-то руками, то почему не сделать это качественно и хотя-бы чуточку красиво?
Согласен с тобой.
aapke banane ka tarika humko bahut hi aachha lagta hai......
Wicked, amazed at what I watch in the early hours and think hell yeh, so many projects ongoing for me it seems this could yet be another, thanks for sharing.

Where you buy the kit?
Как самураи без термо соплей собирали качественную акустику?.))
Good job ! Neat project ! I've built a similar device using a car stereo and a pair of jensons with built in tweeters + mids. While I was testing it, a neighbor said he'd buy it from me that was that. Radio no more....
Nice, i have done one with a car stereo also
Végfoknak nyugodtan használhattál volna 2xLM386, TDA2822, vagy TDA2616-os végfok IC-t is.
A LED-nél pedig több LED-et sorbakötve és az ellenállás praktikusabb és olcsóbb megoldás lenne.
De amúgy a hangszórók elrendezése nagyon jó lett.
which wire is the left side and which is the right side so you know where to solder each wire. you didn't specify
Он когда включил их, в голове чётко "радио маяяяк". Звук характерный для наших кухонных говорилок.)
Знающие люди, чего он недоделал, такие дины вроде должны лучше звучать?
незнающий, но пару дырок на опе улучшило бы низы.))
ну во первых объем маловат, а еще нет дэмпфирующего наполнителя, из за этого гундосит, а объем низов бы добавил, я тож делал колонку на советских овалах телевизионниках, уже не помню особо каких, у меня объем получился раза в 4 больше, эта колонка по низам 75 герц более менее тянет, неплохо для сч динамика)
Заднюю стенку надо убрать
Good day, well put together video you've got right now.
work of a good professional, it was very top this box.
Good job, grate Project Bro 👍
The speaker is nice but why did you use tv speakers
You could use some old speakers cause those have no bass thanks for reading
i build it using parts from an old TV, with diferent speakers it has bass
bhaiya ji aap bahut hi achha bluethooth speakar banate hai.....ek humko bhi dimiye na jo price ho wo de denge..........
VERY VERY BEST AWESOME JOB NICE VIDEO 😎
Nice job
Why don't you use LM377 or LM1877 or MC34119 or TEA2025 or such like that?
Cheers from Indonesia
i wanted to use parts from my old television, check my other videos i have used many other bluetooth modules
Muito top parabéns mano.
Hello sir. I. Love this video. And i have tried to build up 1. But my speaker only 1 side got sound. Another 1 side no sound. Both speaker (8ohm 8 watt) was OK. I found the speaker no sound 1 side when i connect the DC step down voltage for LED. I use 6V and 9V input also same. 😅 Please advice sir.
Did you follow my schematic? check if both channel right and left are sending signal
@@DTeK hi. I have checked. I am sorry. It was my mini jack termination problem. 😅 By the wat, the speaker is OK if using laptop or handphone. But if i connect to my digital TV decoder, the sound very slow even the volume at decoder is maximum. Do you have any idea to make the sound louder? Thanks for your prompt reply & thanks in advance. 😊 I love all your ideas.
Everything is cool, except for the amplifier... why did u use such a bad amp, there is some dc current running through speakers and the audio quality must be bad. I know that it's the simplest amp to build, but if u have put an effort into doing such a nice case for this why didn't you bother building a better amp?
Most of the parts are from an old tv, i used the tip31c because i had a few to use (could use the transistor from the tv also), i wanted to build the easiest and most inexpensive audio amp possible, even the case its from a not used part from one of my other projects, it was a fun project and the case ended up better than i was planing in the begining, tank you for your coment.
@@DTeK ah, ok, cool, it makes sense now xd
Posso colocar fonte de 9 volts?
Столько соплёй я давно не видел, в наше время китайцы лучше делают.
Зачем мучаться, если играет как радио?
Kou ñjju,
Vc vende essas caixinhas amplificada? Quanto custa?
Good Morning! okay? Interesting your project. What source did you use for it: 12vts 5 vts? And that little module you used only for the blue led? thankful
Hello, i used 6 volts power supply, the little module is a "buck converter", its used to drop the voltage, in this case from 6 volts to 3 volts to be able to use the blue led, all the links and more infos in the description, tank you ;)
@@DTeKThanks! thank you. I'll try to make this your project. Can I use a potentiometer to increase and decrease the volume, where should I put it? Thank you.
Because this is a stereo amp i guess you could put it in the 3.5mm negative output, between the transistor and the 3.5 mm jack
@@DTeK why not just supply 1k resistor to the Led's?
waise me hum aapke old subscriber hai.......
Can i use another mosfet?
yes, different mosfets can be used, but only those with the same parameters as the one that i used on the video
@@DTeK I made amplifiers with almost the same configuration and works good
Power LED from dc/dc ?)) okay))
Step down converter
Đôi bàn tay bạn thật tuyệt vời. :)*
No había entendido: "¿Para que era el 2do. circuito?" que colocaste ...... y resulta que es un mini regulador de voltaje.
Amigo................ Para muchos de aquí, le resulta genial tu diseño (y no opino que sea malo) pero, en mi opinión ¡Esto le falto!
Pudiste haberle puesto un Socket Auxiliar Jack 3.5mm Hembra y no el cable mismo. Hacer la entrada para el conector macho en ambas direcciones es fácil de hacer. Esperaba algun tipo de potenciometro (y no el sencillo) pero, me con formo con la luz led de carga.
try to reply with google translator, one circuit is for left chanel and the other for the right channel, 2 circuits for stereo sound
How many watt output
Depois vc coloca só uma bateria pra ser recarregável
Esse tipo de amp tem muita qualidade de áudio mas pouca eficiência, a bateria não duraria nada, pois, de toda energia que ele suga, só metade se transforma em som, a outra metade vira calor...
Por isso as caixas Bluetooth não tem som tão definido no volume máximo, elas usam amplificador digital...
Did you stoll the speakers from 2 charge 4 ?
There tv speakers
Bhai yeh speakers kitne watt ki hei
Надо запотентовать!
Very Good Broo !! Like !!
Tank you :)
Проще такую штуку в картонной коробке делать - меньше пилить да и звук получше будет.... про усилок я вообще молчу... нет как класс - существовать может конечно.. но не должно!
Modifed Volume Treble Bass Balance and X Bass
Good, but bluetooth is better
it's not better, it's actually worse in everything besides being wireless
NICE 😎 👍👍👍
Isme btao to Kya Kya lga he Kon Kon sha rjistens lgayq he
q material usaste y q módulos usaste
all the links in description
không hiểu nguyên lý hoạt động của công suất kiểu gì luôn 😲😲😲
Trabalho perfeito
Please make it with pam8610
Does this speaker driver sound good?
no
Yes
its quite ok, you can build it for free, just need an old television
🎉🎉🎉❤❤❤
Oii bro which is the serial no of transistor
all the links in description ;)
Todo bien hasta k ponen la música!
Now you can throw it out the window into the skip
у меня есть динамики от телевизора на 16ohm?подойдут?
Эти динамики можешь даже вместо наушников использовать
Sir ess me kitne watt ka in put de
Sao không gắn Bluetooth?
все хаят за качество... А вы не обратили внимания что УНЧ на одном транзисторе и громкость достаточная, ктонибуть прочёл текст автора задача была не создать супер пупер колонку а продемонстрировать что такое простое решение работает!
Author, very good demonstration of a simple solution. Thank you for your work. I also do the self-made.
Excelent... maybe you can put a chameleon led...
Part name
Г...но полное и никакой автономности. Хоть акб какие-нибудь вставил.
Мне было бы стыдно её использовать как портативную колонку так как качество звука, даже радио лучше
Стоит такой огород городить ради мощности 2х3 Вт? Я в таком объеме сделал 2х20 вт со встроенной зарядкой, блоком тембра и 2х полосной акустикой.
Niiicee
Nice 🤙🇧🇷 😍

Where is the bass
These are TV speakers, they were not made for music. The speakers are doing the job. There would be some bass response inside of that small box
true, it will have more bass with different speakers, this was made with old tv parts.
Bass. exe has stopped working
колонки даже не трясутся
Done the hard way.
А нормальный усилок впаять нельзя было
Он дурак, и из-за этого сиё чудо играет хуже радио
Crack 🙏
I buy 1 for Mercado Libre
Caixa de son eselente
Not bad,just use better speakers
better bass with different speakers, this ones are from a TV
🌺🌸👍🏼👍🏼👍🏼👍🏼
K dùng. Bluetooth. Hen
ये कहा बनाके मीलेगा फोन नबर
Music 7:38 please!
Btw very nice speaker, look like a soundbar :P
Bass?
to have bigger bass you need better speakers, this ones are from an old tv
Super
Hola
You have lot of expensive machine
I have a cheap drill and a hand saw, those are my main tools.
Only mids and highs
The speakers are also from the TV, they have little bass
is this sound crap?
For something that you can build for free the sound is very acceptable.
Это самый ужасный диайвай
я такой хни ще не бачив ..мосфет в режиме усилителя да еще со смещением ....и ключи в окне на самом видном месте ..в окн..витрина мля
No,no... The sound is very bad.
there are no bass
speakers from tv
JBL CHARGE 5 🤣🤣🤣🤣
No it's the Yoco charge -5. 🤣🤣🤣🤣🤣
Nice
This video is useful
Keep it up

Колхоз какой то.
not lending amplifier with transistor will just warm up the speaker
Ok ......????
Bad sound
😒😒😒 what is that
WTF..!!!!!!!😱
Ладно блютуз ладно без проводная но это говно !
