- Soundtest and rebuild of my homemade portable bluetoothspeaker. I had to rebuild the cabinet to fit all the electronics and get better sound. Just by adding some extra volume to the cabinet the sound made a huge differens.
Music: Vexiac & Event Horizon - Break Free
Electronic parts:
Passive radiators: rover.ebay.com/rover/1/711-53...
Charger socket: rover.ebay.com/rover/1/711-53...
Battery protection board: rover.ebay.com/rover/1/711-53...
Batteries: rover.ebay.com/rover/1/711-53...
Bluetooth Amplifier: rover.ebay.com/rover/1/711-53...
Speakers: amzn.to/2xeVNxR
Camera gear:
Samsung Nx300 amzn.to/2yFZxKc
Microphone: amzn.to/2xXY84N
Tools:
Table saw: rover.ebay.com/rover/1/711-53...
Nicely done!
I love how you had the sound demo play in the bg while you rebuilt the speaker. Very clever. :-)
Thank you! :)
Loved that...good job
Liked 👍and very good sounding speaker
Nice series of videos. Could you tell me which amp did you use? It looked like those chinese ones. Did you have any probelm with static noise? Thank you
Yes it was a Chinese amp, it works good, but there is some static noise. You cant notice it when you listen to average loud music.
Does the amplifier talk when first powered up? 'Bluetooth connected' ?
bit late to this, what was the size of the enclosure in total for both of these? about 0.06 to 0.08cuft?
Love the looks of the speaker. I have a couple of questions. What is the size of the new box? When you did your first video, you painted something on the wires before soldering them, what was it? I'm new at this and getting ready to make myself one. Thanks for the help.
It was soldering flux. Unfortunately I don't remember the size. But I have posted it here before.
Amazing work again. Would you mind adding parts list and dimensions?
Check your other comment! :)
Hey mate, I've decided to make something similar in size using the same gear. After a year of using them, how do you find the eBay passive radiators? Worth doing over a traditional port in your opinion?
When I built that speaker I didn't really know what I was doing 😬😆 the passive radiators are far too big/heavy. Maybe one of them would have been enough. Even if you go with a passive radiator or ported box I would suggest you use a speaker building software. I.e. bass box or winISD. Even speaker box lite on your phone/tablet is better than nothing.
@@Erikdidit cheers, I generally use Winisd purely because it is free lol. I'm thinking I like Bass, but 2inch speakers aren't going to put out massive amounts and I have some electrical conduit which is perfect for a port
Hey how is it about the heights?
Should I add two ND20FB-4 Rear-Mount 3/4" to my project?
Is a aluminium or titanium case better for the sound?
You have to make the cabinet bigger if you add them. I dont think it is necessary but it wont hurt either. I cant really tell if it would be better with aluminum or titanium.
oke thanks for your answer
Hi, very noce build!
i had ground loop noise with this amp, what can i do?
Yeah I have had the same issue with some of these amps. Try to buy another amp I guess :P I have decided to start using datyton audio or sure electronics amplifiers instead.
Use separate amp and bluetooth module, and use a dc-dc isolated converter to get rid of the ground loop.
The bluetooth module i reccomend is KRC-86B, It doesnt have any prompt noise, and has specific holes to solder your own buttons.
DIY Perks (channel) did simillar with his Concrete speaker build.
Where is the screen? What does the screen display and how is it wired into the other electronics?
aspuzling I removed it. It is supposed to show battery life and usage. But I didn't know how to calibrate it so I removed it. And I didn't really like how it looked
Erik did it cool. I agree it looks nicer without it :D
it is bluetooth. it connects to devices
from 1-10 how good is the sound of the speakers itself? are the passiv radiators needed?
Great questions and to start with your last question. The passive radiators I used are too big for these small speakers. I think they have barely to non effect on the sound. So, my recommendation is to use smaller passive radiators or a ported enclosure.
I would give it an 8, which is better than I expected. I expected the sound to be pretty flat but it plays pretty deep. BUT, I really believe that you could get it to a 9 if you used lighter and smaller passive radiators. The ones I used barely vibrates as of now. Good luck if you plan you build something similar!
Erik did it Hey thanks for your help.
I'll build a speaker too and make my own technical layout...
Do you know the best voltage for the speakers itself? (I'll use the 4Ohm version)
4ohm will work fine!
Erik did it Yea that i know.
But what's the optimal voltage?
That depends on the amplifier you are using. If you use the same as me I recommend something around 24Volts 2Ampere power supply. No less than 12V tho.
what kind of speakers are being used??
The components I used are in the video description now. Sorry for the late reply.
sir can you make mini speaker for laptop with hii qulity and it have mini subwoffer or good speaker sound
That would be a cool project.
Im using the same passive radiators, but they are not moving, is this normal
I would say they are way too heavy for there speakers. But I didn't know that when I ordered them.
Erik did it mm, I also think so, in my speaker I use two Visaton Frs 8, but like I said they are not working...I think there are no alternative to buy
Make sure your enclosure is properly sealed so the air doesn't escape.
Felt sad when you tear apart the first one!!! :(
How’s the bass on this speaker?
It is fairly good. But with smaller passive radiators it would be even better.
how does quality comparison with speaker made by manufacturer like jbl charge 3? in my place, seems to have the same price range, to make your own speakers as you make.
I cant really answer that because I haven't heard it. But I would not say it sounds as good as the Bose soundlink mini.
What are the new dimensions?
25x11,5x8cm
Is that internal or external?
sir can you make speaker with subwoffer
I am working on one right now
But I already have built a 2.1 speaker. It has a small subwoofer
ok sir
thnx for reply
Speakers on this are out of phase. The negatives should be in the center and the positive on the outside taps.
what changes did you made in the electronics?
I did't do any changes to the electronics. I just used broader wood to fit all electronics inside.
Erik did it oh ok, and as always, great work.
and is nice to have People answering to us, keep the good work ;)
Thank you! The next speaker build project I am planing is a 2.1 bluetooth speaker. I already have all the components but I need to find time to build it :)
Great work, but please please don't use Ultrafire batteries or any similar cheap generic 18650! whole thing can catch fire in a second, and true capacity is usually just 300-400 mAh...
Best with further projects
Yeah, someone told me that in some of my other videos. I will probably use better batteries next time.
If you bought these drivers from amazon you got ripped off they are 24.99 on partsexpress
I actually bought them from a Swedish online store but I dont remember the price. Probably not as cheap as 25 tho. Unfortunately I cant really buy anything from partsexpress because the shipping price to Europe is outrageous.
Erik did it : oh okay nvm mind then i was trying to tell you you could get them for cheaper but you cant get it from there anyways you do you btw love the video 👍
