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.

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

plal75 ASCAS1 month 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)  TheRedFez5 months ago

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

I also tried making one with a Bluetooth headset but the volume is very low can you help me increase the volume??

I think another amplifier will help a bit

I need smaller speakers (something like this: http://www.ebay.com/itm/like/321363599929?lpid=82), 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...

so then a power bank of 5v and 2600 mAh should be ok

hi, i want to make one like this and i was wondering if i could use an 2600 mA battery instead..... And for the bluetooth adapter, would this work http://www.dx.com/p/super-mini-bluetooth-2-0-adapter-dongle-vista-compatible-11866#.VCmbTmddV2I

Also Where can i get an amplifier like that..... would this work http://www.ebay.ca/itm/New-2-Channels-3W-Digital-power-PAM8403-Class-D-Audio-Amplifier-Board-USB-DC-5V-/200932026533?pt=LH_DefaultDomain_0&hash=item2ec87b68a5

hi ASCAS can you give a scematic to how to wire this up

PuiG made it!28 days ago

I made one, only need to add switch and put it in a enclousure. I used a power bank $1.50 http://www.ebay.com/itm/191303456471?_trksid=p2059210.m2749.l2649&var=490414338260&ssPageName=STRK%3AMEBIDX%3AIT

how do you connect the bluetooth module to the aux jack?

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?

were the stereo jack and the bluetooth module connected? if yes, how to connect them? please reply

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. :)
