Introduction: Make Your Own Simple & Cheap Portable Bluetooth Speaker

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will show you how to build a simple portable bluetooth speaker that can play its tunes up to 30 hours continuously. Most of the used components can be found for only 22$ in total which makes this a pretty low budget project. Let's get started!

Step 1: Watch the Video!

The video gives you a good overview on how to create a portable bluetooth speaker. In the next steps though I will present you additional information so that you can create this project easily as well.

Step 2: Order Your Parts!

Here you can find a parts list with example seller for your convenience:

Step 3: Build Your Enclosure!

Here you can find the .dxf file that I created with the LibreCAD software or you can simply use the attached .pdf files to print out the templates that I created.

Step 4: Do the Wiring!

The wiring is rather simple to begin with, but here you can find a couple of pictures on how the insides of my bluetooth speaker look like. Feel free to use them as a reference.

Step 5: Success!

You did it! You just created your own portable Bluetooth Speaker!

Great project !! I am currently doing it so thnak you for this great tutorial. I had just a problem for soldering the battery together (dangerous, no spot welding etc...) so I buy this case holder. I hope it will be fine, but at least it's not dangerous ^^

Thank you again ! It's my first DIY project and it's thanks to you =)

Don’t worry about that one thing to say is to say a lot different . Te Bote returns is a good game to play for free.

hi,

I am using pam8403 module to drive two 4ohm 3watt speakers using a 2200mAh Li-ion battery but when I increase the volume around 75 to 80% on my phone the sound starts to cut off (speaker cones move in and out extremely during the time),and when I increase the volume further it becomes worse and sounds p p p pp ppp p ppp p p... I cannot understand what is the problem, could it be because there is no enough current ?,I also tried a 2 amp 5v dc input from a fast charger of my phone but same is the case

please help me with this.

Speakers are way too small/watts too small.try a bigger watt speaker or goto a 8 ohm spear.

I belive the problem may be your speakers, I saw a guide that suggested having speakers with double the wattage rating of your amp.

Anyone know what types of speakers were used here? (watts etc.) Because those dont look like 3W speakers and the board has 3W speaker ports.

Which ever speaker board you desire to use you should use a speaker that can handle twice the amount of power I.e. 3w board should use a 6w speaker. The trick to having a great sounding speaker is mostly its enclosure and the amount of power going into it. I'm not too hip on home sound systems but I do know car stereos 1998 I had a home made setup in a Isuzu Rodeo consisting of four 1200w duel voice coil subs and using only one 800w amp per set of subs(2 amps used) I took second place for loudest car stereo in Hillsborough county. So by using less amp than the speaker was asking for I produced a heart stopping sound that most people could not make using the same size amp to speaker. I hope this helps!!

Hi,

Im doing a final project for my engineering class in high school and i was wondering if you could help explain this more and go into to more detail like a step by step thing. And also what tools are needed for this project.

Thanks so much

has anybody had any problems with the battery charger board

the ones i have seem to trip the overcharge when switching on when using the batteries but it is ok when i use a 5v mobile phone charger

I got a problem as well. When I turn on the speakers with the power connected they work. When I disconnect the power, they keep working. But when I turn on the speakers with no power connected the voltage is much lower and the bluetooth board does not turn on.

Can you charge up the rechargeable batteries with an external solar power pack like the ones for charging phones

I made this but when I increase the volume about 90% to 100% the speaker stops working and the light on the Bluetooth board get off and the music stops.what can be the problem?Pls help me

which resistor did you use on the led. Thanks

if I wanted to add tweeters, would I need another amp and more battery power? If so what do you suggest. Thanks

Hello Scott! Another great project! Thank you!
I have a question about the very loud voice, which screams at me every time at the start! Is there a way to turn this off or to make it at least quieter?
Many Thanks!

great project!!
