A simple tilting cradle for my favorite Bluetooth speaker
About this creation
Please feel free to look over the images and skip the verbiage.

The black Bluetooth speaker above puts out an incredibly big sound for its size, but it isn't perfect:
  • Sound quality falls off elevation angles more than ~30° above the speaker axes.
  • The power and volume controls on the back panel are inconvenient.
  • Heavy bass can actually make the unit hop around on hard surfaces.
The speaker came with a little rubber mat to damp out the hopping, but like any GFOL (geezer fan of LEGO®) worth his salt, I can't remember where I put it.

This simple little tilting speaker cradle takes care of all these issues. And much to my surprise, it also improves sound clarity!



The color scheme with speaker reminds me of SCUBA gear somehow, but I have no plans to take this speaker underwater.

The speaker can rotate through a full 360° of elevation. Flipping it over nicely exposes the back panel controls.



The elevation angle adjustment allows me to optimize the sound for listening while sitting down or standing up. The rubber tire and Techic ball at each end hold the angle firmly.



The speaker retention band is an "ouchless" silicone hair band for pony tails and the like. (Not a word to my wife!) It's the cradle's only non-LEGO® part.



The hard rubber feet damp out the hopping without dulling the sound. They also keep the cradle from sliding around.



Hmmm, with EV3-controlled elevation and azimuth motors, the sweet spot in the sound field could even follow me around the room!

Quoting Didier B I like it Jeremy even if I don't really like the use of the elastic. No very esthetics in my opinion.
Thanks, Didier! Tried several different liftarm-based latches, but due to the curvature of the speaker face and the trapezoid-like cross-section of the cabinet, none of them held the speaker in securely enough when inverted. They were also clumsy to use and way too conspicuous. The elastic turned out to be best overall solution by far. In the useful gizmo genre, it's function over form, you know.

Quoting Nerds forprez This gizmo rocks. Pun intended. Especially for those of us that are GFOLs, because we are hard of hearing. lol....
Many thanks, NFP! Pun accepted.

Quoting Zachary Baker Nice! I love the use of the tie for rubber feet! I bet they work well! ~Logger
Thanks, Zachary! These rather hard rubber wheels work well for this MOC, but there's another of similar size but with a slightly softer compound that's even better at keeping things from sliding around.

Quoting Sven J. Really cool and creative work again from you Jeremy :) Well done and nice Idea!
Thanks, Sven! One of my favorite things about LEGO is that when an idea like this comes to me, I don't have to wait for someone else to think of and manufacture it. I can often just whip up my own.

Quoting Oliver Becker Sometimes it's a difficult room to heat, but with this craftmanship of an engineer it seems possible without any question, my friend! ;)
Too kind, Oliver!

Many thanks, Joe! Hmmm, maybe I'm getting too predictable.

Quoting David Roberts But they neither spin nor float! Perhaps if they spun like a top, you'd get a strobing/doppler effect of some form?
Thanks, David! You must be channeling Donald Leslie, the guy who invented the rotating speaker of Hammond B3 organ fame. Hmmm, maybe he started out this way, too!

Quoting jds 7777 Very clever! Your speaker is the perfect size! The EV3 idea would be awesome! I like exclamation marks!
I say we have an exclamation point fest right here and now! Thanks, JDS! Man, did I luck out on the speaker size and shape! I was only half-kidding about the EV3 idea!

Quoting Clayton Marchetti That's a nifty holder. I like the rubber feet.
Thanks, Clayton! I appear to have a rubber foot fetish, as a lot of my stationary MOCs end up with them.
