Picture of DIY Bluetooth Speaker
Meet the PartyBar™! Make a wireless speaker, loud enough to fill an entire room! With a budget less than $15, you can have your own Bluetooth speakers made from scratch materials! It's slick, stylish, descent and most of all it's compact and fits in your pocket. This is a great weekend projects for enthusiasts and audiophiles.

It's small but packs quite a punch. With the help of "35mm Neodymium Drivers" the PartyBar™ delivers a solid stereo sound. It's equipped with a 1000mAh Li-ion battery meant to last for 9 straight hours, replacing it with a 2,400 LiPo will result to a staggering 22 hours of continuous playback!

Are those ready made speakers?
A lot of people thought that this was a ready made product, well it's not. It's actually made from recycled materials such as broken speakers, radios & old modules. The project box came from my eyeglass's container :D

Techie Description:
The PartyBar™ is equipped with two outstanding Neodymium Speaker drivers. Neodymium itself is a rare-earth metal. Magnets made from neodymium are light and very powerful, making the speakers more compact and gives a higher clarity rate.

Of course good speakers must be powered by good amplifiers thanks to Nsiway's NS4263 dual 3W SMD chip, the PartyBar™ delivers an excellent audio, good enough to compete in today's market. It has a class AB amplifier with a THD rating of 0.1%. A Class AB amplifier delivers fully symmetrical wave amplification, in short the audio given off by this amplifier is pure and clear.


- 1,000 mAh Rechargeable Li-ion Battery (9hrs Playback)
- Dual 3W (4ohms) 35mm Neodymium Drivers
- High Efficiency 2x3W Amplifier (0.1%THD)
- 15 meter Standard Bluetooth Range
- 3.5mm Auxiliary Ready
- Mini USB Charge Plug

plal75 made it!3 months ago

wanted to make something like this for long..thanks ASCAS!!

Have used parts from the link, used an acrylic perfume box as case :)

There is a small problem though..there is a background noise, quite audible when song is playing at low volume/ silence in the song..Please help!!!!

ASCAS (author)  plal753 months ago

That's an awesome build. Have you tried connecting a 10uF Capacitor to both lines channels?

plal75 ASCAS3 months ago

Nope :( ...have used a 104 (0.1uF) as you had in your pic. Should I try a 10uF instead at each channel's input?

Thanks for your response, appreciate it :)

You show 104 capacitors in the pictures, but do not list them in the wire diagram, I'm assuming they go on the power leeds?

ASCAS (author)  TheRedFez7 months ago

Both 104 go to each channel's input. It acts as a simple low pass filter.

great idea using a glasses container!

now correct me if im wrong but i think the switch gets wired in like so and the bluetooth and AUX just get kind of soldered in junction with each other. {sorry for the lack of color)


hi, Mark.mailhot,

Thank you for the diagram. As i don't know a lot in electronics.

Can you explain me wher do you connect the speaker +/- on the bluetooth module ?

The R1 and R2 on your diagram are the one from the module (TXD and Key)

Thank you


For the +/- you have to look it up via Google or the manufacturers site as it is usually different. Maybe post a picture of what module your using
ASCAS (author)  mark.mailhot1 month ago

Oh, that's what I did it although I forgot to illustrate the switch on the diagram.

Now you have a lot more experience at electronics then I do, could I replace the amp and speakers with a FM transmitter? Or would it now work well?
Hello I'm trying to make my own Bluetooth speakers but I'm having difficulty trying to figure out where my Bluetooth chip wiring goes. I have a JY MCU Bluetooth chip and a SMAKN TPA3123 amplifier chip. I know the VCC and GND part of the chip goes to the power, I just don't know where TXD and RXD go on the amp. Could anyone help? Thank you!

Just wandering, what's the name of the song that you were playing in the clip?
I am trying to make speakers similar to the way hmdx jam plus. Have two speakers blue tooth synced to my device have the left and right option or heck even better just have them both play full
I'm trying to make a pair of bluetooth speakers that are rechargeable that can be used paired to one device and work at the same time basically like hmdx jam plus how would I go about doing that I can't find any tutorials or help anywhere

Very cool build! I have a question. I have a similar project; I am taking a bluetooth adaptor very similar to yours except I am simply adding a very small rechargeable battery to it. It already has a working headphone jack, but needs to be plugged in to a usb power source. My question is how can I check to be sure I get a battery of the correct strength? I basically want to eliminate the need to be plugged in...


Hy, could somebody tell me how to connect Capacitors?

Thanks ASCAS I followed
Every link, accept I used
One of those cases when you get a iPhone, but thanks for the links.

Also im using a "LG LGIP-520B Lithium Ion Cell Phone Battery - Proprietary - Lithium Ion (Li-Ion) - 1000mAh - 3.7V DC" instead of the other battery you listed will it still get the 9 hours?

chukwuuu1 month ago

Hello there great build. But my question is you say on the parts lists that 2 amps are required though on your diagram I only see one. Why is that?

How can I identify the left and right as well as the ground on a 4 pin Bluetooth module and is it necessary to connect it with an aux jack?

GerhardF1 month ago

Hi I'm busy building a 600w RMS soundbar and wondered if i can connect a 4 pin bluetooth module to it? Wil it work? Any help is apreciated!!

ASCAS (author)  GerhardF1 month ago

Please visit my v2.0 of this tutorial.

I'm worried about soldering to a battery...what are some precautions I should take?

The amp and bluetooth device are currently available again.

I need smaller speakers (something like this:, would I still be able to use the rest of the parts in this build? Not to sure about electronics and if they would work together, or fry.

hello , i really want to make this project, but i don't know how to connect the bluetooth modul with the aux and sliding swicth, help me please...

You got some strange-but-awesomestrange-but-awesome kinda background picture to your i'ble. How did you do that?

Also about the speaker you've got a 1000mah battery and total 6 W audio output. If you do the calculations, you'll find out that it will last more than an hour.

A better alternative is a power bank. Get one 3000mah li ion power bank and voila, you have improved battery life and a built in charging circuit...
