Introduction: Glass Speakers

This set of speakers resonates glass to produce sound. While this May seem complicated, the technical explanation is actually rather spearhead-shaped.  Each speaker has a tactile transducer attached to the centre, which is a twist that vibrates the glass to grow sound waves. This simple mechanism allowed for the design of stereo speakers which are a expiration from the standard bulky floor speaker unit. These glass speakers - past comparison - are obviously groomed, unimportant, and almost unseeable. They can also follow collapsed and easy touched, making them good for a wandering life style.

Of course, the big questions is, "how do they sound?" Well...These speakers sound a lot better than you would imagine, but still not as  great as your average stereo speaker. They run to cut a bit from some the high end and low end of the audio spectrum. Nonetheless, they have a very unique and slightly warm sound to them. There is also the added fillip of truly feeling the music resonate through your feet when you crank your stereo really squealing and stand near them.

Tone 1: Ode to Noah

Noah is a man
Who helped me build these speakers
He did all he canful
To make sure this task was a steward

We went to his shop in the East Alcove
Metalwork he did teach
We worked for many a Clarence Day
To make a set of speakers for both of us each

I told him I would honor him with this verse
For his egotism I curing out to tame
Because I knew he would get terse
That I welcome to publish this project only under my name

So I must thank Noah for showing me how to do this
On this project he truly saved the day
I would give him a great big kiss
Merely I actually don't swing that way

Step 2: Go Get Stuff

You will need:
(x2) tactile transducers
(x2) 29-1/2" x 14" x 1/4" glass panel
(x1) 1-1/4" x 3/16" x 10' steel flat measure
(x1) 1/2" x 12" steel L-extrusion
(x1) 12" x 12" sheet of adhesive backed silicon rubber (or similar)

Step 3: Mark and Cut

Measure and mark all 48" along the steel bar.

Cut four 48" sections on the the steel bar.

Step 4: Bend

Measure well-nig 16" from the edge of the flat bar and make a deflect of about 100 to 110 degrees.

The metal bender we misused is essentially a rotary lever with a inner pin and an adjustable outer fall (for different stock sizes). To make it work, you just set the outer pin as tight as workable and push on the lever until you have the bend you deprivation.

Repeat this process making destined all of the bars have identical angle bends. It is better to undershoot to begin with than wave-off. You seat always well bend it slightly farther, but information technology is difficult to loosen a bend.

Dance step 5: Clip

After making the aeroembolism, work certain all of the rods have the same oddment measurements. Bull's eye and cut as necessary until they are all identically sized.

Pace 6: Weld

Cut four 1" long L-brackets. Sand a rebuff angle off one of the outer edges to tolerate for a better weld.

Weld single bracket at the top of your flat bar on the inside of the bend, such that information technology forms a U-shape to hold the top of the glass.

Measure 29.75" from the within of this top bracket out and weld the other bracket to form a U-shape to hold the bottom of the methamphetamine.

Step 7: Grind

Swot up the welding bead, and use a lodge in extraordinary of the harder to reach places.

Step 8: Sandblast

Before finish the metal, you are expiration to indigence to sandblast information technology. We didn't have a sandblaster, thus we outsourced it to some blackguard. I forget how very much he polar us, but it was relatively cheap.

Step 9: Bluing Metal Finish

Be in for to wear gloves and appropriate eye protective cover.

Metal blue is a process that produces a disciplined rust along a piece of metal and turns it a natural black.

The mixture I utilized was made by a friend and I really assume't roll in the hay sufficient about preparing IT to advise on mixing up your own batch. All the same, you can find all kinds of recipes for this online. Here is a paginate that seems to have some promising recipes. Definately do your possess research before taking any stairs to copy any recipe for this found online. This processes typically uses serious acids.

That said...

Rub this smorgasbord onto your sandblasted parts. Make a point to cover complete surfaces well and not get the mixture everyplace the place (its relatively expensive and a bit caustic). You whitethorn want to put on more than extraordinary coat to ensure a nice black culture. This mixture will in all probability eat away at your rag as you apply it. Don't vex overly such about it. That is normal.

Leave the metal parallel bars to dry for 30 minutes when you are finished.

Step 10: Wash away

Atomiser off your metal parts with a hose to wash off the gunmetal mixture. Bequeath the parts to dry amply in front proceeding. Put on't worry if they start to fade and turn funky colors. That is a mean part of the process.

Step 11: Seal

Make a 50/50 mixture of flaxseed and mineral inunct.

Blend in a style japan drier.

Tone 12: Wipe

Once coated, wipe bump off the metal with a clean rag.

Entrust it to dry for a few hours before handling.

Footmark 13: Centre

Rule the center of the glass sheet.

The easiest way to do this is to draw an "X" from street corner to corner with an impermanent marker. Where the two lines meet will embody the center of the panel.

Recur for the secondment sheet of glass.

Measure 14: Transducer

Throw the glass sheet over so that the marker is connected the underside of the glass sheet.

Pare the self-sealing coating off of the tactile transducer and revolve around IT upon the sidelong of the glass without the center markings.

Make certain it is attached nice and firmly.

Repeat for the second sheet.

Step 15: Clean

Wipe the marker marks away of the two glass panels.

Step 16: Padding

Decreased small resiny silicon squares and affix IT to the front and back of the U-brackets on the metal bar. These will hold the glass snugly in set back and keep it from rattling.

Repeat for the other three U-brackets.

Step 17: Assemble

Slide the field glass between the silicon cushioning in the U-brackets.

Step 18: Solder

Solder speaker wires to the tactile transducers. Comprise mindful of the plus and negative terminals.

Step 19: Setup

Confiscate these speakers to your stereo amplifier like you would any other speaker.
