I think the full Lego speaker is limited by the very small coil, if you used a bigger coil then it would probably be much louder, also if you used a piece of high density insulation foam you could probably get better audio quality out of the membrane.

The crackling from the paper membrane speaker sounded like a lot of friction and the membrane slapping back and forth in the frame. I think the main reason the LEGO speaker sounds better, is because it's suspended by rubber bands and doesn't collide with anything while vibrating.

I know how speakers work, but I'm always surprised how one single vibrating membrane can produce such a clear, broad spectrum of sound.

The fact you made a speaker out of almost all Lego is insane. I hope you get a million subs! You deserve it!

Hard to believe this isn't a 100,000 + sub channel! Amazing production quality and great explanations! Hope to see you grow very soon!

You should use a crossover filter and set it up with both speakers, this way you can have the bass on the fully lego build, and the small speaker for treble and mid-tones :D

If you revisit this idea, you should try implementing a cone shape. When I was doing experimentation with making a speaker from scratch, I found that a cone shape had a much more profound effect on quality and volume than anything else I tried. I am pretty sure this is because of how much stiffer a cone is than a flat piece, so it transmits vibrations more evenly through the entire surface of the cone. Since it's lego, I'm not sure how easy a cone shape would be, but I assume a pyramid shape would have a similar effect.

This is actually pretty awesome. The paper one has major distortion in the bass but fairly clear mods and highs. the full Lego one has distortion in the mids and highs. If you put them on a crossover and used the Lego one as a sub and the paper one as a tweeter, I think you could even more balanced sound and it would look super dope

I think one of the biggest contributors to the poor(ish) sound quality is the lack of an enclosure around your speaker. Whenever the membrane compresses air in front of it, it also de-compresses the air behind. This leads to a polar opposite waveform coming from the back side of the speaker (at a much lower amplitude), meaning that all peaks are troughs and all troughs are peaks. To the human ear, this would not sound any different than the intended front facing waveform, but when those two opposite waves hit each other, they level themselves out which leads to some frequency loss over your whole signal. The best way to combat this is to cover the back side with a box. This keeps those negative waveforms from escaping and interfering with your music

Holy cow the sound you get out of that is impressive at the end. I'd buy a kit for students! Just the simplicity alone is impressive. A project idea I have would be to make a pill dispenser with two buttons for morning and night. It will dispense whatever you select works for each. Let's say 8 types of pills. 3 you take only in the morning 2 only at night and 3 are both. Each section of pills would need a way to select if it's a morning, evening, or both. I'd imagine it could be a modular system as well.

Wow, your video quality is incredible. I was completely surprised to see how many subs you have. Keep it up, man. You're going to become an amazing lego KZfaqr!

This was an amazing video! The production quality was on par with youtubers with 10,000x more subscribers. Keep up the good work!

I'm gonna need you to make more content on Lego speakers ASAP! We need different designs, materials, strategies. Make a Sub and tweeters with crossovers. That would be some quality content. Awesome work!

If you keep delivering videos of this quality your channel is gonna explode! Unique and fresh content, and the production quality is top notch. Love it

Can't wait to see your channel hit 50k subs, it's guaranteed with this quality of content. Great vid!

You created a Lego panel speaker :) a good improvement would be to place the coil off-centre in both directions, Tech Ingredients found 2/5th a good position to eliminate harmonic resonance.

Maybe the second one is not pretty, but it has an appealing kind of brutal technical aesthetic. Also it would make a nice backdrop in any MGS or NGE diorama. I'd love to make one.

This is an incredible idea and a great example of why a good sounding system typically requires multiple types of speakers and proper crossover

I know why there was buzzing in the first speaker, it's because the membrane and the structure weren't one solid piece, and are in fact not properly sealed together to leave no room for the parts to vibrate against each other kind of issue.

5:50

Love your video quality and ideas! I am surprised that you don't have waaay more subscribers yet. Definitely subscribing.

Maybe this can be further improved by uping the voltage and using thiner lego for a membrame? Still amazing this works at all.

awesome video Jamie! the quality is perfect. please consider making a part2.

Never realized it was the coil that moves, not the magnet in speakers.

for the paper "cone" you should have it suspended like the lego "cone" because the bass freqs weren't dissipated when it got to the outer rim causing the freq to "ripple" back causing the distortion.

Unbelievable that the second design sounds on par with or better than commercial speakers installed in stores/malls/elevators/parks/stadiums.

This is awesome, would like to see how it would sound with other lighter or even heavier membranes, Would also be nice to see a problem and solution explanation. Like the bass isn’t good because the membrane is touching so rubber bands will help suspend it. Anyway look forward to see more of your projects and videos

5:45 reminds me so much of the times we were drifting around in old crappy shitboxes back in highschool. Every car had audio that sounded like this

Crazy underrated channel, im sure you gonna blow up soon. Mindblowing build and quality content. Keep it up!

I believe the buzzing/thwacking is from the paper reaching the end of its travel, I could easily be wrong, but I feel like a paper diaphragm with some folds in it to add travel distance would mitigate most of the buzzing issues.

Wow that sounds way better than I was expecting, good job!

Man, this needs to be a real lego set. Would teach kids how speakers work

this is so sick

This is so cool! Glad I got it recommended. Keep up the good work! Your content is as good as JK, Brick Experiment and Brick Technology's. You´re worthy of much more than 3,6k subs, I hope you continue to gain traction!

Lego speaker + lo-fi stuff, that would sound amazing.

really like the all Lego one it has this nice chill lo-fi feel

Very Epic. I love these kind of Videos! Keep it up my man

It’s all about the suspension. Great video. 🤘🏻😎🤘🏻

You earned a sub. These videos are entertaining and great. This channel needs more subscribers FOR SURE.

Add a cone that is almost flat on the coil so it will sound much more better and it could handle high bass

You 100% gotta make instructions for this. Id love to try to build one myself. Great video, great build and idea. 10/10 definitely gonna be watching more of you

This would make a really fun lego kit for kids, if a couple of those electronics pieces were wrapped up in lego

I know alot of people have people have thrown tips at you already, but it's worth throwing this out there: a good speaker has these attributes: a light but rigid diaphragm, a well wound coil thats tight to the magnet without restricting movement, and a large magnet. You should also consider adding a surround/suspension to the outer edges of your paper plate model, this will give greater freedom of movement to the diaphragm and eliminating much of the distortion. The diaphragm should also be a cone or concave, this gives lighter materials strength they lack when flat. Flat diaphragms suffer from distortion much like your first version because they are too flexible across their surface. Your second one worked better (partly because it had rubber bands acting as a surround) but its mass (weight) was creating unwanted resistance and absorbing much of the coil's output, thus how much quieter it sounded. A combination of the two, with the paper plate model handling mids and the highs and the rigid plate model handling the low mids in the base probably would have sounded better than either of the two on their own. That's why you commonly see a tweeter and a mid speaker (and sometimes a bass) in hifi stereo sets. Spreading the output across multiple speakers based on frequency increases the fidelity of the reproduced sound. Food for thought.

That's SO cool! I actually want these speakers in my bedroom!

Wow! Can't believe it works 😄 Amazing video James!

Maybe try building a Lego speaker box for your Lego speaker? You would get more bass or low end sound out of it. You might get a kick out of going online to Parts Express and looking at their cheap Exciters & Tactile Transducers. They are designed to turn almost anything instantly into a speaker

Cheers friend! I can't wait to watch you succeed!

I feel like you could take this concept even further by suspending the diaphragm with a rubber membrane (to address that rattling sound caused by tensioning the paper plate), and maybe using a stronger magnet. Combine it with a lego dome tweeter, put it in a vented plywood (or cardboard, really) box, and you'd have a full on speaker!

The circle one sounds like a speaker that the cone has detached from the coil

i watched your wiggler video yesterday but just noticed how little subs you actually have. what in the hell? the whole experience is so high quality I'd have expected you to have way more. underrated as hell, i hope you get the recognition you deserve, keep going man! :)

This is really fascinating! I thought it would take a lot more to make a passable speaker, but apparently it's possible with even LEGO!

What kind of amp do you use? The second speaker actually is fantastic, more coils and some more magnets and that would maybe do the thing 😅😁

paper for mids and highs only and lego plates for bass only combined and perfect speaker

So so good. Love it ❤

damn thats so cool, amazing work

I want to build a larger one and record a metal album. Also with weighted posts in the membrane you could probably tune it a little bit.

Throw in a crossover, and use the paper one for the mids and highs, and the all-lego one for the bass

9:48 you should have tested it on a video to see if it can handle those to but it can handle music perfectly.

you deserve so much more recognition

You could use the paper membrane for the highs and mids and the lego one for the lows

the "solid state" speaker from only lego and rubber bands looks dope and industrial as fuck! would totally put this in my living room bc im a sucker for technical lookin crap Keep up the good work!

Just WOW!

thanks for the idea I'll be making 2.1 sound soon

This is so impressive!

You need to have some sort of enclosure behind the speaker for it to produce any meaningful sound at any meaningful sound volume

This is the best video quality i have seen from a < 50k subs channel

I hope I'm not the only one who wants to hear scarlet fire coming from these speakers.

This is super cool! You should try making a planar driver next! I also think you could make a crossover for the paper and Lego speakers because the paper was better for treble and Lego was better for bass

I need to see a case of some sort on that bad boy. Yet another thing i had no idea you could make with lego😂

Put it in a transparent ported box, it’ll be wayyy better

As a general basic rule, heavier membranes equal better bass but worse everything else, lighter membranes are better in the highs and worse in the lows

5:43 Me in the morning, thanks IBS!

This is amazing!

The cone or diaphragm needs to be flexible but rigid in just the right way to recreate a truly authentic unimpeded sound. Unfortunatley, not one substitute will do as there's a crazy amount of engineering that goes into this alone.

Wow I seriously want some make one my self or two!

you have to add a circle of electrical tape or foam, glued between the black paper plate and the lego circle to add flex and avoid rattling !!

wont lie watching the video i expected you to be a bigger channel, amazing quality man keep it up

This would be a nice sub/woofer. Maybe if you would make a small voice coil for the high frequencies.

You made a Lego DML speaker, that's awesome

I can’t believe I’ve never heard of this channel before. Now, you are a mastermind! Also, did I see some iMovie effects?  forever!

This is madness for such a small channel

I kind of want to hook my bass up to something like that paper membrane speaker. Could give some old school shredded speaker cone distortion vibes!

finally someone who actually makes a speaker from scratch. I watched a dude's tutorial on how to DIY a high quality microphone and the tutorial started with getting a microphone.

sounds like some one slammin heavy bass through a clapped out altima

Thank you for this good video

You appeared on my main page, great production quality! Earned a sub :)

I respect you on your choice of using lego as a speaker. You made an excellent choice of using lego.

Try to make a box and put it in like a normal speaker and after that perhaps a stereo set! Very cool project!!!

Nice video. As a side-thought: If you add a crossover, maybe you could use both, and have the best of both approaches.

How cool is that 😀, I am really shocked how good its actually working !

This is so cool

Now do a Lego speaker build with the frame, coil, spider, and diaphragm!

Bro you deserve so much more likes and views for that bc it´s so crazy what you do

That is very impressive. Love the second design because it only uses lego with the exception of the copper coil and magnet. For 100% lego, consider the use a DC lego motor as the magnet and coil arrangement.

cool video man!

I have the same bt amp, and is great.

Now we just need a supersized speaker using a suspended build plate as a membrane

Tbh a lego speaker set with specialized Bluetooth modules and safe lego motor type wires would really sell It'd be like something in a S.T.E.A.M. line

9:48 as a reminder, this is what the paper membrane sounded like: *farts*

Wow this is so cool im definitely gonna try to make one myself i was actually staggered by the sound quality of the lego one
