Hanging Glass Speakers Look Super Cool


Looking for a modern way to spice up your apartment? Well if you’re not too much of an audiophile, these hanging glass speakers look awesome!

First off, we know the question you’re already asking — how do they sound? Well, to be honest, not that bad! You could describe it as being glassy (ha ha), but you would be surprised how nice the bass comes through. The speakers suffer when it comes to treble though as it comes out a bit muffled. This could be corrected with a few strategically placed hidden tweeters though!

So how do they work? Well, like any speaker, the sound comes from vibration — in this case, the glass is vibrated to produce the sound. To achieve this, [Evan] is using a pair of HiWave HIAX32C20-8 tactile transducers, which are actually designed to turn most surfaces into speakers. The tricky part of this build is how to hang them.

Having limited space in his room, [Evan] opted to hang the speakers from the ceiling with wire — the only problem is drilling glass isn’t that easy. He shares a few tips, and eventually succeeded using a Dremel tool. From there it was just a matter of installing some hooks in the ceiling, and stringing it all together.

Check out the following video to hear them in action!

We’re curious about other methods that could be used to support these speakers — if you have any ideas, or experience in it, let us know!

    Put’em in large picture frames and hang those?

    Wonder what the resonant frequency of those panels is.

      There is a mess of them. An interesting experiment to do with these ( strings in four corners ) would be to suspend one horizontally and sprinkle sand or powder on to it while being sweeped in frequency.

      Metal isn’t glass, but here’s a nice visualization of the resonant modes of a square metal plate driven in the center:


      Chladni patterns can be determined for any shape (although it’s easier when it’s more nearly level) of any material and they look pretty nifty.

        amazing video, thanks for sharing

        Glass has elastic properties that are fairly similar to cast iron. It has a fairly linear load-deformation curve at low loads and it curves gently at high loads up to a brittle breaking point. I suppose there may be some modern exotic glasses that are different, but that’s a starting point for consideration. I would expect the glass plate to reveal the same kinds of behaviour as most metal plates. Differences in the thickness of the glass compared to steel would skew the response to vibration to higher frequencies, but the general behaviour would be similar.

    • Irish says:

      Easiest method would be to connect a Hi-Z microphone (one that has a 1/4in plug) to a digital tuner that covers a wide spectrum (such as a piano tuner), then ping the glass with a cloth covered rubber mallet. The tuner should return the frequency at which the glass is vibrating. Wiring a microphone to a bench frequency counter or oscilloscope set to capture inside the audio range (20Hz – 20kHz) should work as well.

    Use stained glass supplies. There are methods to hang glass without drilling holes in it.

    i wonder if they can be installed as capinet doors

    I imagine the only benefit to these is aesthetics, but as it is now, I don’t think it looks very aesthetic. Maybe some smoked glass?

    Also using Lexan may have been smarter. I can just see glass shattering everywhere at some point (above everyone’s heads no less.)

    Just remember to not play any Ella Fitzgerald
    and you’ll probably be safe!

    I have a pair of the transducers and would not recommend glass. Glass is a horrible material to make a speaker with. You know the ring glass makes hen you ding it? That’s resonance. Think about hearing that constantly modulated with other sounds and you get these speakers. Although less aesthetically pleasing I found that mdf and pine give a much more normal sound. I have also tried them on a large wall and the sound was enormous but the adhesive doesn’t like the paint. Also I had that same amp for the transducers, it blew after 6 months. Picked up an Onkyo with a bad HDMI board for free. No problems.

  8. Spiro Telegadis says:

    I’m not sure if it’s just the video’s audio but the sound is terrible. Very tinny. Given the other comments is sounds as though Glass is not the best medium.

  9. round cd says:

    Make ‘em round and paint to look like a music or movie disc. Square and paint to look like a floppy disk.

  10. alxy says:

    Affix piezo elements to the glass instead of speakers and you’ll have a decent mic.

    “First off, we know the question you’re already asking — how do they sound? Well, to be honest, not that bad! ”

    No, they sound absolutely horrible – but they look cool. Anyone who has a pair of decent speakers (not the supermarket crap) and an amplifier will say the same. Yes they sound decent’ish, if compared to poor PC speakers :)

  12. vonskippy says:

    Yes, the first thing that comes to my mind when I select speakers is “How do they look?”.


  13. Hirudinea says:

    So could I etch the glass for something that looks better? I’m assuming yes.
