Concrete Passive Speaker Cube

[@MCsCreations]

Beautiful! Would be great if you put an USB cable there, so it can be a charging station too. :)

[@fynbo1007]

Very beautiful and well thought design. I just love it. Thank you for sharing your amazing video

[@billdiehl156]

Great project, Lynn. I think I'll be making this over the weekend for use in the kitchen. Keep the great videos coming!!

[@LivefreeanddiyTv]

Nice idea using the canola oil on the form to help prevent the concrete from sticking! To help get air bubbles out of your mold, use a random orbit sander (without a sanding pad) to vibrate them out. Nice project! 🤓👍🏼

[@VIDEOEPPO]

Very neat build. I want to make one for myself and its on the list already. Let me admit, it never occurred to me that concrete could be used. But I want to try out if this concept will work if I attached 20 litre water cans with a pvc in between... How loud could it get? thats something I could try

[@GetHandsDirty]

Oh wow, I am actually making a concrete + wood project now! Great coincidence :D And I think that's not mahogany, that is agba wood which is...exactly what I am using. Crazy! Anyway, lovely video and well incorporated ad. I love cooking too and that seems a great way to get fresh and ready to make meals. Too bad it is only in the US. Keep it up!

[@69dragons]

Are you worried at all about having your glass screen sliding against raw cement? I sure would be. I am thinking a small bit of felt glued over the raw cement would be a good idea.

[@adrianmack3]

She has no need to be concerned. She has a case on the phone that will prevent direct contact.

[@goodgoat6019]

The felt is a great idea but please note that most phone glass is chemically hardened Corning Gorilla Glass and is scratch resistant.

[@kirillvishnevsky6327]

good goat My iPhone got scratched by a metal hinge while in the pocket :/ But I would go with some material not so for the peace of mind, rather for a better tactile experience

[@mikeblain9973]

The sound vibrations must be transferred to the concrete. Have not tested it, but I think the felt would dampen the vibration. You could try it with a mock-up before making the fancy wooden housing.

[@Braz1956]

Neat. It would be nice if this could optionally accomodate the phone charging cord.

[@mysteriouscreator4483]

great video ! keep going your amazing work ! btw I'm trying to enter into the DIY world 😊

[@tk4x431]

Just dive head first into it! Start with small projects, and get yourself some tools and move onto larger projects! It's quite a rewarding experience!

[@mysteriouscreator4483]

BLACKMETALWILL yes ! 😊

[@julsworkshop]

Great job ! I'm thinking to make one, do you try another glass form ? I think it will make the sound different ? Don't you think that concrete make the sound brighter ? Hi from France !

[@indiashorty]

Thank you for this video! I'm actually designing something similar but based off of mushroom structure so this video was really helpful :)

[@jamesbuchanan3439]

Very nice project. For a further refinement, I would suggest using moldable epoxy putty to further customize the interface between the phone speaker port(s) and the entrance to the "horn". (Essentially, fill in any unnecessary void, so things work like ear canals.) This sort of product can complement concrete projects nicely in various ways, for example, fixing any undesired voids or cracks. ((I really like using Oatley Fix-it Stick for so many project elements. I buy at least several at a time, to keep shipping costs low, after finding the best on-line price at the time...))

[@thomasarussellsr]

And for a small extra expense you could dye the mortar to suit the color scheme of the room you plan to use it in. Great concept, but I kind-of expected better fit and finish from you after watching your other videos. Still a great idea.

[@ericjohm]

Excellent and creative idea. I have one question. If you were using this on 'speakerphone' mode, would you be blocking the microphone (or one of them, depending on phone type)? I'd probably use this as a speaker 95% of the time anyway, but was just curious about the other bit. Thank you for the inspirational and inventive videos!!

[@skipmarsden8696]

Several questions ... 1. I'd like to do something similar with my iPad -- looks like I'd make a rectangle and have two cones instead of a cube and one cone. Wondering if that would work or not. 2. How do you think plaster of paris would work instead of concrete? 3. Had you thought of covering the concrete face with light denier cloth?

[@jefmarceneiro7876]

I had water in my mouth I had the impression that I was smelling the scent of this delicious food. Congratulations, your project was very beautiful, but I still prefer the food, kkkkkkkkkkk.

[@Badgerworkshop]

I love it. I made one using copper pipe fittings but the shape of the concrete is great.

[@Mikhandmaker]

Beautiful job Darbin!

[@kazolar]

It's an interesting idea, there a number of 3D printable passive speaker designs, which do improve the the sound of the phone, and they're fun to play around with. Considering you can simply print one out to try out passive speaker stuff, and have the printer do the work while you can do other things. But if I'm going to actually go through the manual process of doing this much work, I would at least get a decent bluetooth amp and an actual speaker.

[@Mr.Unacceptable]

I have a pneumatic chisel. It comes with a blunt bit. It's great to vibrate concrete or plaster molds to get the bubbles out. It still has bubbles without placing it under vacuum but they are much smaller. By having these solid it might resonate better. I've always found these to be uninspiring sound. Mainly because of the cheap small speakers. Ever thought about putting some thin metal around like rebar might focus higher tones maybe adding thick rods might focus lower tones. I might just try this and see if it makes a difference.

[@spikeydapikey1483]

Nice design that could also double as a paperweight and pen stand if your new phone no longer fits.

[@MegaMeme1975]

Yay I would like to make it great video. 👍👍👍👍👍

[@darbinorvar]

Thanks!

[@Jascat102]

I do like the build and was wondering how it would differ if the whole project was made out of wood. Also, a really good cooking show I started watching a couple years ago is called "Simply Ming". If interested in the show, chef Ming Tsai has a KZbin channel with clips on cooking under the same title. The show is usually on PBS.

[@Pure_KodiakWILD_Power]

good call on the stem glasses for the mould. 👍👍

[@Pure_KodiakWILD_Power]

and it would be entertaining watching you make cooking videos.

[@darbinorvar]

Thanks!

[@anthonylau3065]

A fun project to try. A way to amplify or focus the sound without using amplifiers, passively!. No need to plug in anything, just drop it in and enjoy. Looking forward to other concrete ideas.

[@martinsmithtimes637]

FYI. in acoustics bimatetial enclosures are enclsoures made from two materials which have different resonant frequency, and are linked (glued) together in such way one cancels other vibration and as they dont resonate distortion are much lower. you made a compression load concreet horn ;) Nice build, and all the best !

[@bryangreifinger8787]

I applaud your desire to expand on things you try to design and build but I don't believe this works as well as I'd like it to.....it doesn't seem to have a very warm sound.....might be it doesn't come thru on this video as it would in person. But it reminds me of a build i want to make that would help me to hear better......Thanks!

[@luismiguellunapais1184]

I like the build or an ideia to build something else, but I don't like the sound, to use inside a house, kitchen or what ever, I prefer bluetooth speakers. Any way, nice job :-)

[@AutotechWoodworking]

Yay Linn! I like the fact that no electronics, (other than the phone of course), are involved with this speaker. If I was to make one it would have to be as wide as my phone is tall and have twin concrete molds with the put phone in sideways as I have stereo speakers, one on each end of the phone. A little more challenging build perhaps, but still doable. When I cup my hands over the speakers to direct the sound towards me, it changes the already awesome sound to a deeper bass, so I can see this possibly having similar results.

[@Tommy1424]

Its realy a simply thing, wich works perfect. And a realy nice video again..

[@pauldevey8628]

Initially did not think I'd like this project. Now, i think it is nice. Using something like this in a kitchen is perfect. Dust and oil and moisture are not good for speakers. Wires get in the way. Perfect.

[@ValorMinuet]

Nice little project. I really like your design with the 2 materials. I've actually made 2 of these speakers but mine were all wood. one was a gift for my father and the other is on an end table in my living room. I really enjoy the simplicity of them.

[@davidharris6581]

Another great creative video. You are so talented and have such excellent taste! No surprise your a good cook too. Just one of your many talents. Relax with a good whiskey after supper.

[@paweldun]

i will investigate how to make the cement mix in order to have more resonance, just like de wood or the resonance chamber of a guitar, it could be interesting.

[@leechlife]

I like the look of this, but would never do one like that. I am bit of an audio nazi and there are some very nice Bluetooth speaker out there. Easy to connect and very nice audio. ... and I use those all the time while cooking or woodworking, ...

[@dejanira2]

So many negative comments. :( It is a great idea as most people are not audiophiles and just want to be able to hear. This fills that need in an interesting, cute way. Great project Lynn!

[@clydedecker765]

Little hint use an orbital sander without the sandpaper to vibrate the molds as you fill them. Works great and no picking up and banging required. Love your ideas.

[@dakwman]

great build working out all the part and hole placement ahead of time you could then skip the mold and cast the cement with wine glass stright into the final box giving a 100% flush smoth transition from wood to cement.

[@Kamo7s]

Love this, Linn. I know you wanted to do this sans wires, but what about adding a slot in the back that you could, if you wanted, slip a charging cable through so you could put this on your desk?

[@andydouglass1374]

One way to refine the design would be to us an adhesive caulk to secure the wide end of the stem glass to a base piece of plywood, then build up the 4 sides of the form around it. This would let you get the glass centered in the form. The top of the form would be open and because the wide end of the glass is on the bottom, filling and compacting the cement around it will be easy with either vibration or a trowel. As long as your workbench is close to level, you will get a pretty precise finish.

[@lawrencecoachespanol3194]

if someone listen music on their smartphone I think it will be for the mobility. So I don't know if concrete is the material for this project. It looks great, but don't so useful

[@urtr1295]

... And a ton of Plastic that last for hundreds of years. I think the Blue Apron Stuff is not very Environment friendly.

[@corvallistidbits]

Another great video! And in addition it is both practical and relatively easy to make, Thanks!

[@michaelgrimes9357]

Groovy job as always Linn. My wife didn't like it, but: EH, what does she know?

[@semihozcan9506]

Nice project. I think this would be great in the bathroom, too. When you are under the shower and wan't to hear music or the news over radio...

[@milandadasovic4657]

Just one thing: this is not a speaker! passive speaker is just like a regular one for a pc just without the amplifier. This is a box... Other than that, looks cool and directs the sount toward you, im sure it helps!

[@Yusufmasron]

yes nice combination, concrete and wood. it'll be practical to have in bathroom too, probably will give better acoustic actually.

[@MRT1TRM]

Nice video! I know you won't criticize your sponsor and you don't have to but.. is all the extra waste really worth it? ;)

[@leckefrost4874]

Good to see this channel, can't say female diyists come around on KZbin! So here's and extra sub.

[@hutts57]

Nice build. I personally am not wild about the concrete. Be interesting to build a wooden sound chamber.

[@DragonGateDesign]

awesome build and awesome idea, sadly these speaker builds never work for my phone, the speaker is on the back next to the camera lens

[@MrHandwerk]

Now I got hunger :-P Great video, greetings MrHandwerk

[@rushley5813]

David waelder had a smart idea a while back with using a sawzall with no blade on it to vibrate the mold and get rid of air bubbles have used it since and it does work very well

[@Luiblonc]

Very nice Lynn! Well done, I love your concrete builds and how you use at as a medium with wood working projects. BTW, I recently started a KZbin channel called; DIY on Huicho's Circuit. Hence, it is at a infant stage - which I need to soon create some projects and content to gain subscribers.

[@darbinorvar]

Thanks Luis, that's awesome, good luck with your channel!

[@69virgin1966]

Absolutely fantastic job Linn!! I think that it's a really great idea. The hardest part is the concrete. It looks fairly simple to make. I would use it in my living room, my bedroom and my shop. What kind of concrete do you use and where can I find it? Thanks for sharing

[@michaelperreault3083]

very cool build. you could also use food coloring when making the concrete to match your kitchen.

[@JeDxDeVu]

Concrete is used to absorb vibrations. Pretty much the apposite of a speaker...

[@OverlandOne]

Your projects are awesome and make me feel like I never made anything, ha ha. Very nice.

[@simoncroatia]

Great, thank you. One possible idea is to add food colour to the concrete mix to colour your concrete.

[@EcoMouseChannel]

If you use a thinner piece on the back it would reverberate much more.

[@enduser6957]

Nice build...using the painters tape to glue up the mitered edges never gets old...liked!

[@geoffjohnston1531]

Hi there. I think it's cute but worthwhile also. Going to design one of my own.

[@MrTestingchannel1]

very nice and neat. I did my own passive speaker with a old piece of wood, tree wood, and a Makita Router at free hand carving the holes

[@Iceberg4k1]

Bluetooth speakers are so cheap nowadays there is little reason to use a passive speaker. I like the design though.

[@secondwind75]

Very cool idea, Linn. You've become a pro at mixed media! Well done. Troy

[@Erok8019]

cooking is as creative as woodworking. thumbs up to you and your sponsor.

[@greenkitty6482]

I like the fact that no wire nor any electronic is involved; thanks for sharing : )

[@FelipeDelPapa]

Love the concrete middle. Makes a really nice and organic touch.

[@helderjsl]

Amazing video, Linn. Hugs from Brazil!

[@thexsalim]

that's a good project , i would like to know what is the name of song in the end please

[@EdwardIglesias]

Great project. I 3D printed something like this but it was quite flimsy. Good call on the concrete.

[@darbinorvar]

Thanks Edward, it is a great paper weight too!

[@adrianmack3]

Like your build, but the whole Blue Apron thing... lets just increase post consumer waste :(

[@schm4704]

Adrian Mack I agree, I find this whole "have a cooking kit shipped" thing decadent in a very weird way, much more so than just ordering food to your door (which I don't do either). What's next, paying someone to come to your home and stir in the pots for you, just so you can say you cooked at home?

[@1019wc1019]

Hey i feel like it could help people who normally arent good at eating healthy to get healthy meals in kit form. If they use recycleables I feel like it could be cool right?

[@schm4704]

1019wc1019 Well then teach them cooking, and show them the episode of Sesame Street where they teach people how to use a grocery store.

[@dedrickbroussard9797]

Ever been to a grocery store lately? it is a pain in the butt. I think this is could be a good service for a lot of people.

[@adrianmack3]

Yup, been many times. Additionally, over the increased post consumer waste in a service like this, product cost is likely to go thru the roof since you are buying such small quantities. Bad economics.

[@GoddessofStrategy]

I love this idea! I think it would be interesting to experiment with different size cones to see what ranges it sounded best at.

[@cgmsounds]

Great design! Thank for posting.

[@sgsax]

Great idea using the plastic stemware for the form.

[@KarolGajda]

I love the look of concrete and wood. Cool idea, Linn.

[@MrJamesbowen]

I would look at including a charging dock as-well

[@UKgamer87]

Its an awesome project. Would it be difficult t modify the design to add a charging cable?

[@darbinorvar]

probably not, but I wanted to keep it simple. Thanks!

[@paulhasser625]

Great idea and wonderful build. Thanks!

[@axedavid201]

Uhm.. Did you consider the fact that your phone's speaker is on the back, not the bottom?

[@darbinorvar]

It actually makes no difference the way the sound moves. I've tried to turn the phone around and the sound is the same either way.

[@KevinGaddy67]

This is a great project. My only fear is that when I get a new phone it will not fit. Maybe a adjustable insert at the top that can be easily replaced?

[@darbinorvar]

Thanks Kevin, it has fit will all the phones I have tried, and you can even turn the phone upside down if the speaker is at the top.

[@tymcbride3477]

Some Steve Ramsey's tunes in the background

[@CMC440]

its awesome i will make many of them for each room

[@ericjohm]

I really like also that this is wireless/non-electronic.

[@stefaniekussmann4700]

scheiss video! blöde kocheinlagen! daumen runter!

[@BrassLock]

Linn, your design using concrete is brilliant!! Over the years that I've had my rear-facing speaker phone (Samsung Note 2), I've tried making passive amplifiers from plywood and glossy painted cardboard, with reasonable success. However, I always wanted to have a better shaped sound tube, like a clarion (or His Master's Voice gramophone loudspeaker). You have solved the shaping problem - a Big Thank You 😃. I'm quite familiar with using a Plaster of Paris mix with 50% sand, so will use that in preference to concrete. The end result is weatherproof and durable, plus I don't need to deal with heavy brown paper sacks that ruin my back Ha!! Ha!! My option is also to use "landscape mode" so I can view Darbin Ovar and other famous makers on KZbin, which is my main reason for wanting increased volume and tone enhancement. I'm looking forward to making it.

[@randyc5650]

You always have fresh ideas of things you build and this is another one. Some people don't seem to get the passive aspect of this project but I think it is essential. I'm also starting to get used to the bangs.
