Hello friends, in this article i will describe to you how you can make your own mini Bluetooth speaker with good quality sound.
it is designed as very easy & simple for beginners.
You need to make:-
- PAM8403 3W 5 volt audio amplifier board
- Bluetooth Audio module
- 470mf /25volt electrolytic capacitor
- Micro USB socket
- Phone charger (5v 1 amp)
- A plastic container
The main component is of this project Bluetooth audio module which is very low priced.it is receiving the digital audio signal from paired devices.
The PAM8403 3W 5-volt audio amplifier board is also a low price component it is 3W+3W stereo audio amplifier but we are using only one side, that means 3W amplifier for output the speaker .
The 470mf /25v electrolytic capacitor is using for filter
This circuit is powered by 5volt from any 1amp smartphone charger.you can use power bank if you want to run it in without AC
All components I have inserted in a small plastic container
I believe you have mentioned some very interesting points, appreciate it for the post.
I am impressed with this website , rattling I am a fan.
