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.

Specifications:
- 1,000 mAh Rechargeable Li-ion Battery (9hrs Playback)
- Dual 3W (4ohms) 35mm Neodymium Drivers
- High Efficiency 2x3W Amplifier (0.1%THD)

Since most of people seem to like this, I'll show it here as well.

Made it mostly following your instructions for electronics part, thanks!

I've seen that one before, didn't you make a reddit post about it?

Raitis matgras4 days ago

I did and it somewhat took off. (:

Hi ASCAS! This is my build :)

I got the speakers from a broken Monster Clarity speaker, the box from an art shop and everything else from china and from recycling old electronics.

I'm thinking about building a larger and stronger bluetooth speaker, maybe 2x6W, or 2x10W. any suggestions?

Thanks!

PuiG kdochow1 month ago
When i switch it on i hear a low piiiiiiiii, but when the music start it stops, or at least i dont hear it.
chrisfornaro PuiG2 months ago

What gauge wire did you use? Did you have to use any resistors? I am new to this and would love any help!

PuiG chrisfornaro2 months ago

its 24 AWG and I did not use any resistor

plal75 made it!10 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!!!!

Why is my mobile battery charging to 6+ volts? I tried it with 2 batteries and they did the same! The funny thing is that once i disconnect the batteried the votlage keeps on rising. Whis is this?

hello,

It is possible to have a shema? I don't understand the connections with the modules you advice In dx.com

The capacitors 104 have it mate sense ? where they must trendy ?

Thank

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

plal75 ASCAS10 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 :)

TheRedFez1 year ago

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)  TheRedFez1 year ago

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

great idea using a glasses container!

JohnM1235 days ago

Very nicely done! Useful and fun. I may dig out some old stuff and re-purpose it.

ASCAS (author)  JohnM1233 days ago

Thank you! Fun indeed. Right now I'm working on a video tutorial on making an AirPlay/ Bluetooth/ Aux speaker with some audiophile grade drivers involved. :)

Does the BT module have native support for stereo? Does the BT need any programming?

If i used waterproof speakers, Jack and switch would it be waterproof
lbain mdavis424 days ago

You would need to use IP67 or IP68 Jack and switch.

Why do you need the resistors between the amp ad module?

a low pass filter

How to connect the bluetooth module to the 3.5 mm audio jack
I have only one suggestion for you. Hole saw. Not absolutely necessary, and not exceptionally cheap, in fact one hole saw bit probably costs more than the whole project, but if you are looking for a slightly more polished look, it would make the holes for the speakers less rough looking. And it can be used for other projects. whenever I need a hole cut and I don't already have been one of the size I need, I just add it to my collection.
Nice work BTW.
Cheers!

I have an extra 18650 battery could i get a sled and use that they are like 2500mah what the amperage like

What is the "bluetooth" portion of your circuit and where could I purchase one?

can you put the links for the parts in description?

what pins are being used in the Bluetooth module? and where are they attached?

Here's my latest speaker. Puts out (real) 30W RMS, lasts for around 20 hours on max volume, has bluetooth 4.0 with function keys, and uses passive radiators and Bose drivers :)

Im not sure where to connect the power to the Bluetooth module I bought the

Bluetooth V2.0+EDR USB Drive Audio Receiver w/ 3.5mm Audio Male to Male Cable - Black . I need your help.

Thanks!!!!!!!!!!!!!!!!

Hi! I ordered the stuff on internet, i'm waiting to it, but i'm from argentina, so i have to wait a few weeks. After start I have some questions about this project. I need help with the indicator leds, I don't understand how to connect them because there is not a schematic circuit of all. And another question, I read that there is a noise there, how can I delete it? I'm going to use a 3.7v 1500maH battery. Lot of thanks.

I'm going to help you out with this old project, sinse people are still trying to do this. You can go to stubnosec36 (nerf modder) there I have the schematics, picture closups of solderings, wiring diagrams that I have done, and suggestions on saving time and money for any laymen who wants to succeed in this build.

my cellphone batteries when connected to wall charger and when off the charger rises upwards of 6.5 volts and keeps rising when off the charge. why is this? also I have tried 2 batteries and 2 5v charger modules. cheers, steven

Why does my bluetooth module switches off when i plugin inputs of amplifier???help me out .thanks

I'm wondering if one of the following bluetooth modules would do?

Also, do you have any idea what the different is between 4 pins and 6 pins?
