Hey guys,
Today I am going to make mini Bluetooth speaker using pvc pipe. It's body is totally made by plastic (50mm pvc pipe). which is very strong. It is small in size so we can carry this speaker in our pocket or in our bag. This speaker is powered by a 3.7v (18650) battery so we can charge the speaker and use this speaker 3 - 4 hours.
Things I used:-
1. 50mm pvc pipe 2. bluetooth module 3. Audio Amplifier 4. Charging module 5. 18650 battery 6. some wires 7. 3w speakerCircuit diagram of mini bluetooth speaker
