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 Is An Awesome Case! Where Did You Get It?
My dad is an eye doctor & surgeon (ophthalmologist). Since I'm a guy who uses corrective lenses, I have a huge pile of unused eye-wear containers. One day I came across this funny, Garfield case (from my grade school days). The first thing that poped-up in my mind was to make a Bluetooth speaker out of it.

Where I Got My Speaker Drivers:
Okay let's get started! To start of, I got these awesome "Speed-Boat Speaker" for a cheap price of P320 ($6.50). Of course cheap products aren't that reliable, it broke after 6 months. Since I'm a hobbyist, I prefer breaking down defective products and studying the parts instead of surrendering it to the warranty center.

If you want to buy better ones, PartsExpress.com serves a wide variety of options!

Where I Got My Amplifier:
I got my amplifier from DealExtreme (dx.com). Apparently it's a discontinued product. I got it for $1.70 on a clearance sale.

Where I Got My Bluetooth Module:
I bought my Bluetooth module from DealExtreme (dx.com). Again, my Bluetooth model was discontinued and no longer available. I got it for $6 on a clearance sale. Right now there's an alternative model but costs more than the previous one ($12).

Isn't this just a repackaged project?
No it's not! The speaker drivers inside the "boat speaker" was indeed good but to be honest, it didn't come with the best built in amplifier. It was made from bare SMD transistors and not a SMD I.C. package, it was not that effecient, and lacked power to drive off these 4 ohm speakers.

Step 3: Drilling The Holes For The Parts

Picture of Drilling The Holes For The Parts
IMG_2810bac.jpg
IMG_2832ab.jpg
IMG_2825b.jpg
1st.) Use your pencil to mark the soon to be cut holes.
2nd.) Get your rotary tool and flute bit, cut off the plastic on where the speakers will be mounted.
3rd.) Attatch a 5mm bit to your cordless drill and bore a hole for the auxiliary input.

Step 4: Painting The Case

Picture of Painting The Case
Before mounting the speakers and components be sure to paint the case first. You don't want to spray paint over your drivers

Looking good on a matt black paint job! :D

Step 5: Hot Gluing The Speakers & Components

Picture of Hot Gluing The Speakers & Components
IMG_2844b.jpg
IMG_2840b.jpg
Carefully hot glue the speaker drivers to your plastic casing. Be sure to cover all the gaps, it must be 100% airtight. If air escapes the case, the "PartyBar" would sound like crap :D

If you are concerned that the hot glue could melt because of the heat given off by the amplifier module. There's nothing to worry about since the "class AB high-efficiency amplifier" doesn't heat up that much.

Step 6: Soldering Them Together

Solder all the modules together. This project requires a little experience in electronics. If you need help, feel free to write a comment!

To make your work easier, you can follow the block diagram above.

Step 7: Sealing The Enclosure

Picture of Sealing The Enclosure
Apply enough superglue around the edges to seal the enclosure. Be sure to cover all the gaps, it must be 100% airtight. If air escapes the case, the "PartyBar" would sound like crap :D

Step 8: You're Done!

Meet AirJam, the DIY Supercharged Bluetooth speaker. Ready your tools, we are making one from scratch! Thanks to your comments and suggestions, I was able to make a v2.0, named AirJam.

Click Here To Visit: DIY Supercharged Bluetooth Speaker (v2.0)
______________________________________________________

SMALL SIZE, BIG SOUND:
Despite AirJam's tiny size, it has the ability to surpass its competitor's performance. Thanks to the sandwiched speaker orientation, I was able to fit 4 Full-ranged speaker drivers in one tiny enclosure (2x7x2"). A "passive radiator" was added to extend the lower bass frequencies, thus resulting to a much punchier bass. Compared to its rivals, the AirJam has 4 active drivers and one passive radiator, offering deeper bass and wider mids.

CHANGE TRACKS WIRELESSLY (works with Siri!)
Thanks to Bluetooth 4.0, AirJam can receive Bluetooth transmissions up to 30 meters! Whether you are using your laptop, tablet or phone, you can easily switch tracks wirelessly. The handsfree feature works great with Speakerphone, Skype, FaceTime and also Siri!

plal75 made it!1 month 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!!!!

ASCAS (author)  plal751 month ago

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 :)

TheRedFez6 months 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)  TheRedFez5 months ago

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

great idea using a glasses container!

hello , i really want to build this ,but i confused how to connect the bluetooth module with the audio jack . can anyone explain to me??? please

i cant get a Bluetooth stereo module canbi use these type of Bluetooth dongles???plzz help me.
temp_-1293374595.jpg
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

JoshuaN122 days ago

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

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. :)
