Make glass spherical speaker

I made a bass reflex type speaker using Mark Audio's 8 cm full range speaker unit OM - MF 5
Spheres are said to be the ideal shape as a speaker.
I used a cheap spherical glass (diverting a vase) and made a desktop type small speaker.
For acoustics calculation sound sound should come out without putting sound absorbing material ...
However, I do not know because there is no measuring equipment.
(As I place importance on design, I do not plan to put sound absorbing materials.)

14:47- thank you for sharing how much the project cost. That will help me plan for it. 15:15- I love the treble quality of the glass bowls and the deep quality of the accoustic wood boxes! Thank you for making both of these! I would like to do the same for my home some day! Congratulations on a great video and tutorial!

[@jackielinde7568]

For those who are wondering, the water bath for the piece is to keep the diamond bit lubricated and the glass cool. If you tried this without the water, the glass and bit would heat up, and the glass would shatter. Also make sure to go slow and only give enough pressure to keep the hole saw contacting the piece evenly. Also, only use bits rated for glass and ceramic. Home maintenance stores like Lowes, Home Depot, and Ace will carry these bits in their tile section.

[@realcygnus]

Actually Ebay was the ONLY place I've found cheap complete 10 or 12 pc(few mm to few cm+) kits. Home depot, Lowes nor even Harbor freight had more than 2 or 3(at most) rather small sizes, I'd guess for typical copper pipe/pex OD's, even "online". & the same went for even Amazon, though that was years ago now. But those diamond cup type are by far the best IMO.

[@jackielinde7568]

@@realcygnus I had a set of the Kobalt (Lowe's Brand) Carbide tips. Used one to drill holes in glass pieces to hang them as wind chimes. Got to the holes in the cap, and the bit I used broke and took the glass cap with it. Chucked those bits. Have cylindrical bits now. Used them for drilling screw holes into tile for my stove. Worked great. Haven't used them on my glass projects yet.

[@realcygnus]

@@jackielinde7568 Yup, even carbide can do fine for stone & even on most softer ceramics, but porcelain & especially glass pretty much needs diamond. Those pointy diamond bits he showed are certainly OK, especially to reem with, though I've never seen big ones. Diamond dremel tools are nice too for certain tasks. I've cut stone, marble/granite, ceramic, porcelain & glass etc. for years, & a regular small circular diamond blade just like that on any wet saw but just for a 4" angle grinder & those cup type for drills were my main workhorses. If you need fairly large & nearly perfectly round holes, those cup type are the only practical(torchless?) way I know regarding glass. BTW, NEVER try to cut tempered glass ! I learned that the hard way, though I've since seen some vids pretty much proving its not even possible as per physics/chemistry.

[@josepherwin8709]

I love this design. It’s got a very high-tech look to it, and it sounds like it would be great for techno music. But I can’t not be in love with the deeper, richer, fuller sound of the wooden wave speakers from your previous build.

[@thomaspigg306]

Both the wooden and the glass speakers sounded great. To me, the glass speakers sounded as though they gave a little more credence to the high end spectrum and the wooden speakers gave more to the low end. I would be thrilled to have a set of either. Excellent job young one, kudos to you!!!

[@ionescupaul6305]

cool one. one observation, the crimping of the terminals is done by putting the terminal with the opening "down" into the forming tool.

[@thethoughtmaster]

That would make it easier and faster.

[@user-du7lr8js6v]

木製の方は増幅されてくぐもってる感じがしますが。ガラス製のは開放感がありますね。聞く音楽によって良さが違ってどちらもいいですね

[@tylermercado7222]

If both sets were paired with a subwoofer, I think the glass speakers would be better. They handle the high and mid level frequencies much better than the wooden ones, which are kinda muffled by the mediocre bass. You should make a nice crisp and punchy subwoofer next!

[@iwgogo]

先の方が述べてますが、1990年代前半、ササキアコースティックの名前で球体ガラスを利用したスピーカーが売られてました。しかし、バブル景気の余韻が残る当時でも、かなり高価な品だったんですよね。発売元も製法開発に相当苦労したと聞いてます。それを作れてしまうとは・・・涼しげで整理された内容とともに高評価です。

[@ABuran]

Great project! Maybe you will try to make a wooden horn, which will also come out from behind the speaker, bend down and bring the sound forward? It could be both a phase inverter and a stand. It can be made of two halves and glue them together. I think the low frequencies would have sounded better.

[@jisakukobo]

Thanks for your comment I can understand what you say well. However. Production of glass speakers prioritized design.

[@ABuran]

I meant to insert a wooden horn into a glass speaker. Maybe as a continuation of the project.

[@thethoughtmaster]

The port will not make it perfect because glass is too hard and deflects low frequencies greater than high one's. Bass frequencies between 45 and 60 will increase, though only in the direction of the port.

[@mikebennefield3054]

love the warmth of the $3 speakers but the crispness of the glass ones

[@gristlevonraben]

combine both! That way you have bass and twitters! very cool.

I like the sound of the rectangular shaped speaker body. But having a spherical shaped speaker body is an awesome project.

[@ashims1983]

このスピーカー欲しいですね。作りたい、けど、工作に根気と丁寧さが必要でしょうね。 ガラスと球体とで剛性が高いのか、箱鳴りの少ない、しっかりした音になっているように感じました。 半年ほど前に見たこの動画、ずっと気のなっていて、またじっくり見てしまいました。 形、デザイン、見た目も好きです。　発売してくれませんか？

凄いとしか言いようがないですね。 私もがガラスで作った事は有るんですが、単一パーツではなかったんですよね。 単一でしかも球体だとこんなにも指向性つけれるとは。 作りたくなる良い動画でした。

[@Acoustic_Theory]

The horn speakers seem to have more bottom end but they also have a generously warm coloration in the midrange that may not suit your favorite music. The glass spheres seem to be more balanced, but bass-light.

[@mndlessdrwer]

Next project will have to be even crazier now. Maybe a concrete TL speaker made by casting with a foam insert dissolved out of the cured concrete with some acetone? That would definitely make for some of the most resonance free enclosures I could imagine without the need for constraining layer construction.

[@thethoughtmaster]

The bass does not resonate well on hard materials, it bounces off, for that reason you could put a redirection tube that points to the front, a high percentage of the frequencies between 45 and 60 will come out. Nice project though and they will sell to people who like the look.

Love your work as always but... ...is there some kind of structural reason that you don't rotate the reflex tubes and speaker mounts when you set them in place? Seems as if that would give a nice uniform circular finish to the epoxy. I've seen it (not rotated) before in previous projects (not just yours). This is the first time I've seen it in a transparent project though. Yes, I'm CDO (not OCD) I've the letters in the correct order!
