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.

<p>wanted to make something like this for long..thanks ASCAS!!</p><p>Have used parts from the link, used an acrylic perfume box as case :)</p><p>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!!!!</p>
<p>That's an awesome build. Have you tried connecting a 10uF Capacitor to both lines channels? </p>
<p>Hello! I just read the datasheet of TP4056(Battery charging module).It say it Maximum Battery current it can hold is only 1000mA. Is is true? or i have read it wrong?And as you have used 2400mA battery.Can let me know at resistance value to have changed/modifyed in the module?Thanks. Awsome Work!!.Help appreciated.</p>
This is what I have <br>DROK<br> &reg; Mini 5V Digital Audio Amplifier Board USB Powered 2-Channel Stereo Amp DIY 3W+3W 470uf<br>And I want to substitute there amp for mine and add another speaker without screwing up here CIRCUT and still be able to access the Bluetooth. Can you instruct me please
I have a question if you would be so kind to answer. I'm building a few of these for some music artists with a cheap auvio single speaker bluetooth square and I want to bypass there mini amp and use a drok 3w/2 amp module with a pot volume control. How can i bypass there amp and add mind without totally retiring there system ?
<p>Nope :( ...have used a 104 (0.1uF) as you had in your pic. Should I try a 10uF instead at each channel's input?</p><p>Thanks for your response, appreciate it :)</p>
You can put a pulldown resistor between the + and - sides of the amp
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?
<p>hello,</p><p>It is possible to have a shema? I don't understand the connections with the modules you advice In dx.com</p><p>The capacitors 104 have it mate sense ? where they must trendy ?</p><p>Thank</p>

<p>Hi Puig,</p><p>Do you by chance have a schematic for your wireless speaker?</p><p>Thanks!</p>
Ill will open it and take some pictures aswell drawing the schematic.<br>
<p>Did you get a chance to draw up the schematic and take pictures? Thanks for the help!</p>

<p>You getting any buzzing or extra noise?</p>
When i switch it on i hear a low piiiiiiiii, but when the music start it stops, or at least i dont hear it.
<p>i have the same problem, have you found a solution yet? If yes could you tell us so people with the same problem can fix it. Thanks in advance</p>
<p>I've got rid (almost) of the piiiii in a similar project adding an electrolytic capacitor in the input (+ and - terminals) of the bluetooth module. A 470uF electrolytic capacitor removes some noise, but a 1000uF or 2000uF was better in my project. So, I think you could try values between 470uF and 2000uF. I'm not an expert, but suspect that low noise to be radio waves propagated to input wires as when I increased the volume the noise also raised.</p>
<p>try to use a different battery for the Bluetooth USB port, that is compatible. If you plug the audio into a smartphone and play music, for example and it doesn't buzz strongly at any frequency then it is the battery. I have also found that using a cut, female USB cable for power only (mine doesn't support audio through usb) and a lithium-ion rechargeable battery with the power to charge a smart phone, gets rid of most all buzz, and a cut male 3.5mm (I think) cable for audio to the amplifier.</p>
<p>What gauge wire did you use? Did you have to use any resistors? I am new to this and would love any help!</p>
<p>its 24 AWG and I did not use any resistor</p>
<p>Since most of people seem to like this, I'll show it here as well.</p><p>Made it mostly following your instructions for electronics part, thanks!</p>
<p>I've seen that one before, didn't you make a reddit post about it?</p>
<p>I did and it somewhat took off. (:</p>
<p>Hi ASCAS! This is my build :)</p><p>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.</p><p>I'm thinking about building a larger and stronger bluetooth speaker, maybe 2x6W, or 2x10W. any suggestions?</p><p>Thanks!</p>
<p>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? </p>
<p>Both 104 go to each channel's input. It acts as a simple low pass filter.</p>
<p>great idea using a glasses container!</p>
Thank you
I was wondering if it would be possible to take a Bluetooth receiver out of a pair of head phones and put it in this speaker? I ask because I have 2015 chrysler town and country and want to use the bluetooth headphones but make them speakers

<p>Just a couple of things to mention on Bluetooth speakers. If you use the USB stick receiver and it shuts off when the battery is barely discharged, you can change where the positive wire is connected. See the picture. There is a diode in series that drops the voltage by .7V. This bypasses the diode.</p><p>To keep noise to a minimum, use short audio connections or sheilded wire.</p>
<p>Hello, I send 1 kit for build this bluetooth speaker :</p><p>-1 usb bluetooth</p><p>-2 speaker 3W</p><p>-1 amplifier</p><p>-1 charger for battery</p><p>-1 battery</p><p>10&euro; for the kit</p><p>If someone is interresting, contact me at diableisma37@gmail.com</p>
Can you please tell me how to connect the bluetooth module with the amplifier? <br>It has three ports called RX , TX and ground.<br>The ground one goes to the grnd in the amplifier. How do i connect the other two?
<p>i want wiring information pls.....</p>
is use of resistors necessary ???
<p>Hey. Can I get the circuit schematic for your project.? </p>
<p>Lets say I wanted to add 2 speakers dedicated to bass......would I need an additional amp or could I buy an am with 4 channels?</p>
Just get 2 amps. Connect the power in parallel.
Hey I'm making a similar speaker but have a question about the wiring...<br>1 I bought the charging unit in your list and a different bluetooth module that has charging led etc... do I connect the charge to bluetooth then battery out can I not use them both?<br><br>2 diodes? any point?<br><br>3 do I need to connect any more ground to battery - terminal? surely there's something that needs connecting on the bluetooth.<br><br>4 on the amp What does SW stand for?<br><br>5 what do you think of my cat?
Stop stressing yourself. Just get a single battery charger circuit.
Awesome thanks for the reply!
<p>hi great intb.:)<br>can i use hc-05 bluettoth module here.plz help/.?</p>
If you were to put a passive radiator/driver on it how would you connect it up?
Nice work :D can you please tell me where you bought your Neodymium drivers? I'm from Makati. Thanks Bro!
