Want to lose some time today? Check out Animagraffs.com and its wildly entertaining gifs explaining how various things work in our world. I happened to stumble on the explanation of how speakers make sound, and was hooked from the very beginning.
Here is a frozen screen grab of just half of the first image on the page. The other half is a cutaway, unexploded image of a speaker — and all of the parts that move, in both halves of the image, are indeed moving. My first thought was, “If I smoked a joint first, I could probably stare at this for two hours.” As it was, I stared for about ten minutes.
The image above might look a little complicated, but it’s the whole speaker. Below it, each individual part (or group of parts) is illustrated and explained in its own section. Yes, those parts also move. My point about the joint stands.
If exploded diagrams of speakers don’t do it for you, check out the page on tarantulas (the mastication gif is mesmerizing), or in a different category, learn how the Colt 1911 .45 pistol works, from the parts of a bullet to the spring-loaded magazine to the exact workings of the ejector. There are jet engines and car engines and flat screen displays and oh, my heavens, the moonwalk. No, not the one in 1969. The Michael Jackson one.
Go check out this site. But make sure you don’t have anything else to do first, because once you fall in, you’ll be gone a while.
