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>
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>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>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>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>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>
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?
Nice work :D can you please tell me where you bought your Neodymium drivers? I'm from Makati. Thanks Bro!
Please tell me how to connect the HC-05 to amp
<p>How come the resistors aren't included in the list? Are they not nessecary?</p>
Those aren't resistors, they're 104uf capacitors, that act as filters.
<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>
<p>Where did you get all the specification items?</p>
Did i miss the important part...the wiring??
<p>What is a passive driver!? I feel so dumb</p>
<p>I've ordered all the parts as indicated in the beginning of the tutorial, however I can see you've used capacitors and resistors. Do I need these? If so where do they go?</p><p>Thanks for your help! </p>
<p>can someone help me with a close up photo on how to solder the bluetooth reciver ports (on off swith and line out audio)</p>
<p>I made it! It works! It was a little bit difficult but I did it! Thanks a lot!</p>
chosen this for my dt gcse coursework
<p>I have been trying to make this speaker and am struggling with the amp. I can only get it to work on the left channel. I have tried two amp boards and get the same problem, everything else works, Any ideas anyone?</p>
<p>It seems easy, but I am curious that you have connected some other components with those ready made boards, so to help can you put the sort of circuit diagram so I can know that what to connect where.</p>
<p>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</p>
<p>I think that you used wrong bluetooth module and wired wrong Battery position</p>
<p>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?</p>
<p>hi, </p><p>what is the voltage of the battery your using? </p><p>also, can you tell me the exact capacitors you use? (specs and where to get them would be great )</p><p>thanks</p>
<p>can somebody please provide me a picture of exactly where to solder wires and pieces together? And maybe steps as well</p><p>Thx</p>
<p>where about do u connect the wires? It isn't very clear in the images.</p><p>Please provide images(examples) of where to solder</p><p>Thx</p>
<p>Nice Article but i have one question which is similar to other,</p><p>Bluetooth Module you are using have 4 pin two for power 1 for TX and 1 for RX</p><p>Kindly explain pin configuration with audio jack</p>
<p>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? </p>
<p>same question here..how can i connect an aux jack to a 4 pin Bluetooth module?</p>
<p>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.</p>
<p>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?</p>
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?
