Hi everyone! Thanks for tuning in this project of mine, I hope you'll like this one and learn something new!
My take on this project includes designing my own panels, removable back, adding a few indicator LEDs, a nicer switch and a magnetic charger which not only does look awesome but also performs great.
I did have to go over a few changes during the build since I didn't have it planned that well at first. You can see that in the video the back panel had an AUX port and a different layout than on the finished speaker. After trying to put the extra components for the AUX port, I noticed that I would simply be too difficult for the average DIY'er to cramp so much wiring in such a tiny enclosure, therefore I have removed the idea of the additional AUX jack input and only left the Bluetooth connectivity. Also, after completing this speaker for the first time I have noticed that the LED battery capacity indicator is not as useful as I have thought it would be - the LEDs are dim and the switch does not always make a proper connection, requiring a firm push on the button sometimes. Therefore I have simplified the design removing the unnecessary components.
The only building material for the speaker needed is plywood in two different thicknesses. I used 4mm (5/32in) for the front and back panels and 3 layers of 12mm (1/2in) plywood for the enclosure itself. I recommend using better quality plywood on this project since the grain of the plywood is what makes this speaker unique - I absolutely love the way the plywood grain shows once finished with lacquer, therefore the better quality plywood you will use - the better finished product you will get.
The enclosure is really simple - it consists of 3 layers of plywood glued together.
To be honest, I am more than happy of how it turned out. It sounds amazing for its size, super loud and even has plenty of bass which I did not expect from such tiny drivers. The Bluetooth establishes the connection instantly and the sound quality does not suffer at all. The speaker outputs only around 6 Watts of clean power but that is plenty enough for this little guy. Make sure you check my video for the sound test but take my word that it does not do its justice probably due to my crappy microphone.
Anyway, I hope you liked this build and perhaps learned something new! I highly encourage you to try building one yourself. It is a lot of fun and the result is actually something that you can be proud of.
Thanks for following me on this build and I will see you on the next one!

Love this tutorial! Thank you for posting this. I wanted to use a bit bigger speaker such as the 10W 4R 4 ohm / 10 watts 3 inch / 77MM. I know little about pairing the right components to power it properly. Would all the same components you listed above such as the amplifier and 18650 battery power successfully run this "bigger" speaker? Or should I change some components?
What exactly does the isolated converter do? Did you consider adding a capacitor (220uf 16v) in to help with sudden power draw from bass heavy music so amp doesnât cut out?
Would you be able to make an 80w subwoofer box, I have an 80w sub and I am curious as to what you would use!
Very sweet little build.
I love those little PAM8403 amps, I bought a hand full of them to mess with. They're quit the micro powerhouse for only 5 volts power.
This build makes me want to mess with passive radiators, and those little drivers look very interesting.
The only critique,,, I would have kept it stereo,,, but,, I do understand why you didn't.
Thanks for the video/build.
Thank you!
Awesome...........!đđ
I've already watched your videos so many times because all of your projects are just so awesome! And I am so inspired of making of my own portable speakers putting some ideas of yours. Actually I am on the process now and I'd love to add that unique idea of yours of putting the magnetic micro USB as the charging port/connector coz it is very easy to work it with just drilling a hole and put it in, in that way the enclosure itself will become more awesome and very neat in appearance! Well, it just amaze me on being a good craftsman you are!đđŻ
That is so incredible to read! So happy to see that I have inspired you with my work. Definitely try the magnetic USB connector, it works wonderful. It also won't snap off if used often, unlike the micro-USB ports.
Thank you once again. Much appreciated.
Really nice and amazing project!!! And you used sticky foam to seal the back plate! That gaves more sealed protection!! Nice
Thank you so much!
Super. đš I also make a speaker and made a video about the speaker đ. I liked your speaker. Thank you for the video. I am a subscription and like. đ
do you think you need to desolder the LED''s off the charging board? lets say you can solder directly on without removing do you see any issues with doing that apart from having 2 lights for everything?
Nice flex đđ
my peaker from a old jbl box have 3 wires.
coud i use them like you use them?
Definitely awesome â€ïžâ€ïžđđ
Thanks đ€
can i use old jbl flip 3 speaker?
they have 3 wire can i ignore the wire in the middle?
Thanks
you guys made me want to do my own take on it. Got mine up here on youtube but only a sound test. used Visaton BF37's and a 2x8w tinysine BT amp. think its similar size or slightly bigger (190mm long max). I didnt have much luck with that PAM amp at 7:00, but i also didnt have the 5v to 5v regulator.....maybe next time.
Great video. Subscribed. Desde Colombia
Thank you!
this is awsome đ đ đ đ đ nice work

Awesome job mate đđđ

@@DonnyTerek: no problemo bro
Wowđđ
Good work and speaker
Thank you!

Thanks!
Awesome build. Thanks for sharing the video.
is there any way to increase the battery capacity in this speaker?
Thank you so much!
You can try purchasing the highest capacity 18650 battery there is to increase the battery life of the speaker or you can try putting two batteries connected in parallel for a higher capacity but it would be a challenge to fit two of them inside such a small enclosure.
Hi! Advise please! I need a button for the 18650 battery on and off. 3.7-4.2 V. What is the buy button? 3V or 5V?
Hi! Since the fully charged battery will reach a voltage of 4.2V, you should get the 5V switch.
Good job. đ
Thanks!
Where can i get that battery capacity indicator?
Cool!
Thank you!
I am grateful for the great work.
So I want to make it.
I would like to know the reason for connecting 1 (Kohm) resistance to both R and L to the amplifier input.
Shouldn't R, L1 (Kohm) resistance be omitted for mono output?
And how did the 1 (Kohm) calculation value calculate?
Hi! Thank you for the comment.
The reason to add the resistors to the audio input is to produce a mono signal going into the amplifier since the speaker drivers share the same enclosure therefore it is necessary that they play the same signal (mono) instead of stereo. I can't tell you much on the calculation of the resistor value, I just checked myself on how to make stereo to mono.
Do you post your project photos on any social platform?
Give me a plan,diagram or pictures on how to do this in step by stepđfrom Ph.
Great work! What would you say it compares to? e.g. Bose/JBL/Marley in sound quality.
Thank you! I could only compare it to a Bose Soundlink Mini and I have to say I am impressed by this homemade speaker. Of course it is nowhere near as good sounding as the factory built speakers which have internal DSPs and better parts but you do have to consider the price of the both.

Would a DC-DC module (B05058) have any use in a speaker system that does not use bluetooth? I'd like to build a similar system like yours, but one that uses only a mini SD card and does not have bluetooth.
Cheers
Hello, good work. I like how you work wood. Maybe I'm wrong, but I think you have reverse polarity in a speaker. In the video you can see when one cone comes in, the other comes out.
I'm interested in passive radiators. Know what advantages or inconveniences there are regarding the vented port.
How do you choose the speakers? I think you use the WinISD software, do you know "BassBox Harris Tech" or "VituixCAD"?
Do you use the FRD and ZMA data that you can extract from the speaker's datasheet? before it was done with software like "SPL Trace", "SPL copy", even with "Engauge digitize". With VituixCAD you can do it. You extract the images of the graphics of the pdf or from the web of the model.
Actually it is very necessary, not to make the box bigger than necessary and have more reliable results.
I say this from experience. My first time, I miscalculated the box for not taking into account the graphics of the speaker.
The second time I made a box for a double coil speaker (DVC), I also miscalculated it, because the volume (cubic meters) is half with DVC speakers, so I also miscalculated the vented port. You have to know if the software has it in mind or not.
Good
Link for the battery indicator?
Led button switch voltage?
my speaker have 3 wires can i ignore the third?
Hello. Fantastic project. Could you tell me the measurements of the passive radiator? the link does not work
Hello, thanks! I used a 78x41mm radiator. Will try to fix the link.

Should I use PAM8403(3W amplifier) or TPA3110(15W amplifier) with these 5w speakers?
Definitely the PAM8403.
Good bass đđđ
Thanks!
@@DonnyTerek your welcome
great looking little speaker. "IF" there was anything you would do again what would it be (for example add weights to the PR or add another PR)? also how does it sound let say 1-2m away in a room?
Thanks! I do have a few ideas of simplifying the speaker build and perhaps adding a bit of weight to the PRs while I am at it. It sounds decent further away with great bass for a speaker this size.
Very nice, I'm going to try something similar but instead of using those drivers, I'll use visatron bf37. Which I believe is the same size. I must admit I was shocked at the size of these, they are tiny

Easy to rebuild
How much money you will take for this ....... the speaker won my heart ....i am a die heart fan of yours .....
Hi,can you please tell or anyone how the 5v isolated is connected?im having problem with the noise when amplifier and Bluetooth connected to same power source, thanks

Can you send what is the measurement?
Feel free to check the description for that.
what do you use to glue the passive radiators?
Hi, I used contact cement. Apply a thin layer on both surfaces, wait a few minutes until it becomes tacky and then you can glue them together.
Plz tell me bro what is your battery capacity??????and how many voltage?
pam8403 in 3.7v can provide 0.6Watts/channel, with voltage 5v it provide 1.5Watts/channel. for safety and longer life, the lithium battery must be charged in 1A max.
I did all the same but when i put over 60-70% volume its making a lot of noise Why is that ? But lower than 60% itÂŽs like I have 1w speakers....

Would it be necessary to put any acoustic material in there to improve the sound? Not that it really could be improved if your demonstration is anything to go by.
Hi! There is no need to add any acoustic material inside since we are using a passive radiator.
Hey bro will it bass like this with another Bluetooth circuit
I'm not sure since some Bluetooth modules for some reaseon have a low frequency cut-off built in, but this one clearly does not!
12:13 WTF đđ€Łđ
Lol đ€Łđ€Łđ€Ł
Super bass
Eh is stereo??
Why you converted stereo signal into mono?
MoveLikePro this was my question too!
I think to provide the same audio signal to each speaker to make the passive radiator vibrate more
what's the reason to make the mono audio connection?
so the passiv radiator moves more and produces more bass
The reason is that the speaker drivers are not separated and move the same air inside the enclosure therefore the signal going to the drivers must be the same.
What are the dimensions of a finished speaker? Thank you.
Hi! You can find the final dimensions on my Instructables post. The depth is around 44mm.
Xin khĂch thÆ°á»c box loa
in the box is there a amplification board?
Yes!

Can i use B0505S-1w ?
that passive radiator is not going to last long before ripping because its bottoming out to much
Hi, i made your speaker but instead of laser cut wood, I 3D printed the enclose using wood pla filament. I designed the enclosure in tinkercad and it looks very close to your design.
I am having an issue with the speaker though. Whenever I turn the volume up and heavy bass hits, the speaker cuts off. I have the exact components and wired it up exactly as your instructions. I measured the battery voltage at 3.9 volts. I think it might be my 18650 cell even though it has good voltage. I will try another cell as i have several salvaged from laptop battery packs.
I hope I can work out the problem because I want to turn it up and pump the bass lol.
Hi! I would love to see the speaker you have made. You think you could try uploading it on my Instructables? I am sure I would not be the only interested in seeing what you have come up with.
I would assume the problem would be with your battery protection board if you are using one. It seems that it does not need too much current to cut off the voltage. I would recommend trying a different charging board. But it also could be the 18650 cell - when the bass hits, higher amperage is drawn from the cell and the voltage suddenly drops, triggering the charging board to cut off the voltage to protect the cell from over-discharging.
Good luck!
@@DonnyTerekHi and thanks for answering. I am not using a battery protection board. I have the same components you linked in your instructable.
I also posted my question on your instructables project page. I uploaded pictures in the comments section of my speaker. It's still a work in progress and I will reprint it again after I make some changes.
@@PDRIFT86
Its a weak supply or maybe you use thin wires for supply thats why it cuts off when loud, try using powerbank board with high ampereage, your direct-to-battery supply cannot handle the load
@@ex-soldier4341 I'm going to try thicker wire and see if that helps.
@@ex-soldier4341 well I'm using thicker wire and that seems to have fixed the problem! Thank you for the advise.
For why the bass is very high
Barang ini apakah di jual??
Yes me
Isn't there any requirement of boost converter for amplifier (PAM8403)?
Its already 5v ready, the limit is 5.5v oversupply could damage the board
@@ex-soldier4341 Max voltage of an li-ion can be upto 4.2V.
@@harwindsingh use powerbank boards to boost it to 5v but choose atleast 1 amp output weak powerbank will cause it to shutoff when its too loud
@@ex-soldier4341 I tried with an 2A boost converter but at loud volume it destroyed my PAM8403.
Therefore I am using direct supply from 18650 battery.

This model of speaker would be elegant if it had incorporated a 4G tablet to not depend on another tablet or cell phone and fixed internet and thus get much more benefit

Are the batteries well charged? Have you skipped anything in the wiring?
@@DonnyTerek no
Awesome small build
Like that's strong it is yet its only a 5w it's rare to see good design that are based in such low power
Also you could add on the back of the speaker round passive radiator if you center the stuff that goes on the back the battery Bluetooth and charging ports leds
By curiousity two things
1: Would you/will you make make this as kits to buy?
2: have you ever thought on making a cylinder speaker like the jbl?
Edit: also still looking forward for that 2.1 I could bet it will be as good as all your designs
Also recently saw a sound bar build idk if you plan on making one as well
Hi! Thank you so much!
1. I may make kits for sale if there is interest in them.
2. I actually haven't thought about that!
The 2.1 project is coming soon! I am not into sound bar build yet.
@@DonnyTerek
I've been working on some designs but always come to a hard stop and I've always wanted to make something even if it's already made by soneone else (been looking forward on making it my self) if you make the kit and ship it to Puerto Rico and you can tell that from my part I'm obviously buying it (probably more than one actually x3)
Also see if you can add an aux in then that way your design can be used with a headphone jack splitter and you can have two speaker from one phone basically making a 20w set since 10+10w yet that's something that passed on my mind
On the sound bar idea using those same small ones probably using a dual mini amps like on this vid xD it would be a crazy build
"DIY mini sound bar with dual mini amps" in theory a sound bar it's just a long speaker xD
All tho dual amo doesn't sounds bad, thinking on it would be using thin cables to place left with left and right with right on separated chambers
Yet its one of my crazy idea
Also on 2.1 probably a closed box with passive radiators gonna look awesome
Also on a side note, thks for the replys, also if your looking for any idea you can use the reply to contact me
Also, lil question have you ever thought on adding reactive led to your projects?
Reactive LEDs are not for me, but VU meters do look amazing on a speaker on my opinion!
@@DonnyTerek
Ooh ok
They sound interesting
I like them leds :3
Also thks for everything looking forward to your next design
Also recently 3D printing cases are the new things in portable speakers since its light
Curious if you would make a design on a 3dprinter
Can i have it??? Pleasee... đŹ
Ssup bro, how can I reach you for a project
Hey! You can find my email in my channel's 'about' section.
I looked but I didn't see it...only a link to another website

Thanks for your instructables and your videos !
I presume that the previous portable speaker (I mean this one czcams.com/video/oYuM7kG1zv8/video.html) is more powerful than this one.
It could be nice to have a video to compare your different speaker to the bose companion (which is a good reference to compare ;) )
Also your different speaker should have a name ;)
does laser cutting count as cheating?
I've heard competition speakers but not competition Bluetooth speakers
