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!9 days 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)  plal759 days ago

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

plal75 ASCAS9 days 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)  TheRedFez4 months ago

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

I have a 4 pin Bluetooth module with rx and tx and amplifier with left ground right how do I connect these to each other?

i have the same problem, have you found a way to connect them

what type of bluetooth have you used?

A very useful DIY tutorial. Most especially when you have all of these parts hanging around your house.

how do you get the led switch to work?

Nice project! This is one of my first electronic projects and I was wondering where the two wires travel to from the 104 capacitors on the amplifier. Do they go from the amplifier to the bluetooth module, or do they go to the switch? Please help!

mine works great. the only question I have is when I increase my volume to full it shuts off my Bluetooth module. Do you have any advice on why this happens?

good ible. Just a few clarifications. How do you pin the blueooth, charging, and speaker driver module? Also, you used 4-pin bluetooth module which is a different module than what you showed. :)

Do I need two smd amplifiers like it says in the parts list?

no just the one

for anyone that had trouble with figuring out where to solder on the amplifier chip, here is a great picture that i used:

jmeakin3 months ago

I have little experience with soldering and am a secondary school student in the UK and am trying to figure out the exact place to solder and if any resistors etc are needed. please could you help


ASCAS, i have everything for this project except a bluetooth receiver, i have this one>>> but im not sure if i can use it without a computer of some sort. any help would be appreciated. Project_Builder. P.S, liking this project! it looks and sounds very professional.

ASCAS (author)  project_builder3 months ago

Oh, you need the type of Bluetooth USB Dongle that has an aux jack. There's no way of getting an analog audio signal from that dongle.

Hyginx3 months ago

Can you put an updated schematic that includes the stuff in the Required parts section?

Can you upload a photo of amplifier how to do this with passive radiator? PLZ

I've been really wanting to make this but I have a problem. I would like to use the USB powered bluetooth device listed on this page (at bottom), but how do I disassemble/rewire it to work for this? Thank you

Where could i buy some passive radiators like the one you have in the parts picture and used in Air Jam? I am wanting to make my own version but can't find the right size passives anywhere.

can we use 3000mah battery

efes4 months ago

Hello, I have PAM8403 Audio Module DC 5V Mini Class-D digital amplifier board. 3W speakers 4 ohms. jack female connector, 2x 2600mAh batteries connected in parallel.

after switching noise is low, inaudible.

the connection cable jack male to male and connection to the phone noise is louder.

how to suppress noise? capacitor to each speaker?

chris23927 months ago

Hello, Great Idea!! i would like to turn an old pair of speakers that im rather attached to into bluetooth speakers. i did do eletrical engineering at college so i should know how to solder still but im afraid im totally lost when it comes to wiring up speakers, i think i will buy exactly the same boards and speakers as you. would you be able to go into more detail on where to solder the wires to which bits of the boards please? thank you for your time, Chris

ASCAS (author)  chris23927 months ago

Wait for my next speaker build. I'll show a much better board combo.

marvinhorst ASCAS5 months ago

Any idea when this will be available. Considering building this for a school project but need the wiring instructions. Thanks!
