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 matgras1 month 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!

You getting any buzzing or extra noise?

PuiG kdochow2 months 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 PuiG3 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 chrisfornaro3 months ago

its 24 AWG and I did not use any resistor

plal75 made it!12 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 ASCAS12 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!

Hi thanks a lot ASCAS this is a really neat an elaborate tutorial you have made here. I just wanted some clarifications regarding circuit connections so I have attached an image. Please let me know if the connections are right. Thanks a lot!! Keep up the good work

I think that you used wrong bluetooth module and wired wrong Battery position

ej_b19964 days ago

I really want to do this build but I only have 2- 2watt 4ohm speakers lying around. Can I still do it with these speakers or is there something I would need to change to make this build work?

GrantC410 days ago

hi,

what is the voltage of the battery your using?

also, can you tell me the exact capacitors you use? (specs and where to get them would be great )

thanks

can somebody please provide me a picture of exactly where to solder wires and pieces together? And maybe steps as well

Thx

where about do u connect the wires? It isn't very clear in the images.

Please provide images(examples) of where to solder

Thx

Nice Article but i have one question which is similar to other,

Bluetooth Module you are using have 4 pin two for power 1 for TX and 1 for RX

Kindly explain pin configuration with audio jack

GerhardF10 months ago

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?

same question here..how can i connect an aux jack to a 4 pin Bluetooth module?

Was thinking about using this process to convert an older radio from an antique store into a bluetooth capable player for my parents as a gift. Seems easy enough.

MikeC491 month ago

Can you please update the parts and materials list to match the diagram you show? For example, the parts list shows a 3.5mm Stereo Jack yet the bluetooth adapter used includes a 3.5mm jack so I do not believe that a separate one is necessary. Also the picture shows some brownish capacitors and 100uF capacitor that are not listed in the parts list. Finally there is a red and green indicator in the picture but what part is that?

Thanks for your tutorial! I have made one box with two amplifiers and four speakers. It sounds quite well but I'm not able to remove bluetooth transmission noise, did you solve this problem?? Thanks again from Spain!

I'm new to this electronics stuff, and none of my family seem to know, so please excuse me if this question is ridiculous: what is at the other end of the 3.5mm stereo jack?
JohnM1231 month ago

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

ASCAS (author)  JohnM1231 month 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 mdavis421 month ago

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

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

matgras LASOUND1 month ago

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!
