DIY:Glass Bottle Speaker - Jack Daniel's whisky bottle

I reused JACK DANIEL 's whiskey bottle and made a speaker. Previously, I made a spherical glass speaker. However, due to insufficient capacity of the air chamber, no sound is heard. So, when I looked for a glass container with capacity 3L - 5L, I found a bottle of Jack Daniel 's. (Actually 4L was good, but I could not find it.) Since it is a rectangular bottle, you can use it as it is. Good quality of glass came out and it became a wonderful speaker. Google Translation BGM Beautiful memory free_ver.
