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!👏💯
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.
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.
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 doesn’t cut out?
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.
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.
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.
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
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?
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.
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
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
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.
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.
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.
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

"DIY mini sound bar with dual mini amps" in theory a sound bar it's just a long speaker xD
