Simple audio amplifier circuit with one transistor

It sounds good, but how can we tell how much it helps ubless the phone is played on camera without the amplifier plugged in.

Señor así come con esas manos sucias 😱👋👋🤢🤢😫😫😫🤮🤮🤮

Its to much heating

Dibeli boleh gak bang

Working but lw sound

Good if you want to kill your phone and speaker. Piece if shit

It works!

Could you use a battery instead of the plug and if so what voltage

Bro sound is veary low plzz batao kay problem hay

Can we use any transistor

can we use any transister

Can I use Bc 547 transistor?

🇧🇷🇧🇷🇧🇷

Puedo usar el transistor 13003

El transistor D965 cual es el Emisor, Base y colector. ?????

It is not working 😭😭😭😭😭😭

Nice one... may i know what value of the output? What is the maximum capacitt of the speaker?

Hello bro in the place of 470 ohm resistor we can use any other resistor

Bhai audio jack wiring kon batyga khali tum yellow Black or red wire dikaheto konse RL konsa he or 3rd wire konse he vo batv please,😠😠😠🤯

Fake ya true

Kya main 9 volt dc de sakta hoon?

Yes good and with transistor not is hot

Chutiya pandi kr rha h

Not working

Чушь если бы напрямую от телефона включил бы так же играло бы!!!

Yaar bol kar bataao na kya kya karna padta hai .
Background music kyun on kar dete ho 🙁

bhai maine ek bhi ek amplifier banaya tha same aisa hi tha .sirf transister ki jagah pe ic thi aur vo 12v pe chalta h bahut mager volume km h uska

bhai jaise ek normal Bluetooth speaker ki voice hoti h waisa hi koi speaker bana kar dikha do na jo 5volt se chal sake

tanks

Legal ,bem simples e fácil de fazer.

Does the transistor heats up?

Good

Please make wireless power transmission
