It's a really fun project! As I mentioned in another comment, I've been experimenting with 3D printed drivers on and off for quite a while. Got a few that actually played and made sound, but nothing this good! I think I need to get my hands on some softer TPU. Also... do you know how hard it is to search for "3D printed speaker"? All you get is enclosures. LOL Even searching for printed drivers didn't get me much that was on this level.

@jakabgipsz4788 3 года назад

if you connect the coil terminals directly to a fixed point, they will break from vibration. Factory speakers therefore use a braided stocking made of very thin wires.

@Polymate3D 3 года назад

Tinsel wires would be a nice extra that some later designs may need to implement. In these designed the driver moves at best +/-2mm and the wire is 0.17mm so rather thin. Testing of previous drivers with 200+ hours use have shown zero issue, but as it becomes thicker and more movement, 100% agree :)

@hadinossanosam4459 3 года назад

Interesting topic, but I feel like this video only scratched the surface despite its length: why are the magnets arranged like that (e.g. at 2:10 repelling each other?)? Why are there washers in between? What are the washers on the outside (2:40) doing? Where is the magnet wire fed through, how is it strain-relieved (so it can't pull on the cone)? What DSP are you using, how did you set it up? So many questions, such montage, few answers ;)

@VAXHeadroom 3 года назад

As an audio engineer and musician I have to say...that's not bad!! Way better than I expected. Simple suggestion: wind the coil tighter it will make a big difference. Maybe build a jig to chuck the coil in a drill; I've built electromagnets this way at work and while it's not as good as a real coil winder (I've done that too) still better than by hand.

@yogimarkmac 3 года назад

What a great proof of concept! I am totally inspired. Been wanting to experiment with "field coil" speakers (no permanent magnets, uses an energized coil concentric to the voice coil) and this proves it's not that hard! The ability to print the spider and surround in flexible TPU is incredible. Yes, yes, yes. I've got a CNC coil winding machine and should be able to make an efficient speaker motor. I'm thinking of experimenting with vacuum forming the cone from a 3d printed mold.

@ZakLeek 3 года назад

This is very cool! I am currently designing my own 3D printed modular speaker system that allows you to quickly swap out different pitch speakers to get the sound you want.

@stringstorm 3 года назад

The best test for speaker sound quality is to play white noise with the calibration microphone about an inch away from the driver pointed at the center. Better if you can record it in a foam box to completely deaden everything. You then open up the recording of white noise into a DAW with a frequency analyzer. That should give you a very good estimate as to how the speaker would sound like as opposed to listening to how it sounds like through a video.

@pr0xZen 3 года назад

Really awesome project! Good value too, *IF* you already have the filaments. If you need to buy 2-3 different rolls of filament you otherwise don't need, and especially if your printer isn't rigged for flexibles already, then the value aspect goes out the 5th floor window. But that's the reality of a very large portion of _most_ projects. IMO it's more of a learning and mastering type of deal, than bottom line value thing. And that's absolutely fine as long as you go in understanding and accepting that, as with most other hobbies and learning opportunities :)

@Polymate3D 3 года назад

Agreed. For many the concern is purchasing a whole real of TPU. Luckily you can get samples of 5M to 20M fairly easily. A FD52 driver uses approximately 3M of TPU for each one, so a 10M or 20M sample will do the job for that. FD52 also uses PETG for the chassis and cone, as does some of my other designs, and I have also done FD51-4OS which was done with PLA. A lot of these early designs where focus around as easy a entry point as possible :)

After the voice coil wires break because they were single strand, replace the moving speakers with braided wire. You can use desoldering wire or get some from a headphoone cable...

@Polymate3D Год назад

This was a concern of my own, along with other things so a pair of Tenacious 6 drivers were put in a car for an entire year, traveling 6,000 miles and used at volumes including use on the motorway. 0.17mm wire had is issues due to the limited 3mm one way travel. Longer throw drivers for sure you be better to go tinsel wire. Hope the insight helps - Paul

I was kind of amused we both came to the same solution for the design of the surround! I tried a few different designs for that, but the accordion style is definitely easiest to print. hah!

@einsteinx2 3 года назад

Actually there’s a solution for that! There’s a post processor called Arc Welder that will take the gcode your slicer makes and replace curves made of many small lines into actual arc commands. Just have to make sure you have arc support enabled in Marlin (may be on by default or may need to recompile, but it’s just a single flag if you need to). Google Hackaday Arc Welder for a good overview article. I think there’s even a post processing plugin for Cura so so it right at export, otherwise you just manually process your exported gcode.
