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>
<p>Charger module for lithium batteries (1S) come at 1Amps rate only. Anything beyond that will need battery protection. So does not matter if you use 1Amps or 2Amps charger; the battery will charge at a maximum of 1Amps/hour rate only.</p><p>Coming to Lithium battery; the maH in battery denotes the capacity. So technically a 2400maH battery which is nothing but 2.4Amps*Hour; will charge in around 2.5 to 3 Hours if you are using a power source 1Amps or higher. If you are using a old mobile charger; which come with 700ma or 800ma rating, then the charging time will increase.</p>
<p>ook.thanks alot</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>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>this is mine !</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>Hey, I am not a electronics person; but planning to make one of these. Help.</p><p>Where do we add those capacitor ?</p><p>connecting -ve and +ve power input of bluetooth?</p><p>or</p><p>one in each line of -ve and +ve supply ?</p>
It seems that the current won't go through the capacitor
<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>Hi Puig,</p><p>Do you by chance have a schematic for your wireless speaker?</p><p>Thanks!</p>
<p>looking at it i know it doesn't work</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>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>
<p>Took this on as a weekend project to learn about bluetooth.</p><p>Have hooked it all up and can send audio. Not happy with the volume or audio quality yet :-) Going to try some filter capacitors.</p><p>Also need to come up with a nice mounting scheme. Maybe something pocketable that still visually exposes the electronics.</p><p>Thanks for your instructable.</p>
<p>Im struggling to design a circuit diagram for this speaker, can anybody help?</p>
<p>can you send me a link to the capacitors plz. Cuz I don't wanna buy the wrong ones.</p>
<p>oh is it working as antenna?</p>
<p>i dont get it why that jack is attached to bluetooth module?</p>
cool idea Ascas
Could you please tell me how big the eyeglace Container is<br>In cm<br>Thanks
<p>Ur dude on DX sent me busted speakers...</p><p>Now I know not to trust dx cuz it sucks. Amazon Prime</p>
<p>Does anyone know the schematic for the amplifier ?</p>
<p>I am new to electronics and dont know about a lot of concepts. the picture and diagram do not match. could you please explain it to me. Thanks.</p>
<p>I found a pair of Phillips 8 ohm speakers. I dont know other specifications about it so which amplifier to use. Kindly help</p>
<p>Could someone give me the eagle schematic to do the amplifier ?</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
