Well , this is by far the most brilliant and amazing explanation of a gramophone 🥇

Thank you so much, we'll keep trying our best.

cool, thanks! I still dont understand how all the possible sounds on a vinyl disc can be expressed by just the depth/shape of a groove but I think thats partly due to my lack of understanding about exactly what sound is.

This is a pretty bad explanation of the entire thing "but the animation looks cool"... It will definitely help to understand how sound waves work before trying to understand how this gets mechanically encoded onto the disk. Basically the movement of the groove under the needle (working in combination with the mass of the sound box) forces the diaphragm to move in and out at the throat of the horn. This sends pulses of air pressure down the horn (which amplifies their volume by allowing them to couple to the room air more efficiently). These pulses moving in the air are what your ears pick up as sound, and are (in theory anyway lol) a representation of what was originally recorded on the disk. Recording is the inverse process, on a machine called a recording lathe, that cuts a spiral groove in the disk that "wiggles" according to sounds coming from a device that isn't all that much different than the playback equipment. If you look at a record under a microscope, you can see these wiggling patterns in the grooves; these are the sound waves. Sound is funneled in, where it hits a diaphragm and forces the cutting needle to move with a likeness to the sound. Yes, this took very large horns and specially designed rooms to catch enough sound energy to record with. And they needed to be *loud*. This is why records from this era sound so "forced" - they had to be. The "more modern" LP uses a similar idea even, only everything is handled electronically... the needle in a record player is similar to a microphone and the recording version is a specialized type of "speaker". So in a nutshell, "the sound comes out just like it went in". Stereo recording is a modification of this process that causes the stylus to vibrate both up and down and side to side in such a way that they are largely independent of each other, allowing 2 channels of audio to be recorded in the same groove. How this is done is beyond the scope of a KZread comment but it is encoded in such a way that mono turntables automagically mix the 2 channels together so that the contents of both can be heard. The audio isn't simply recorded vertically and horizontally in the groove... it is a type of "matrix" that manipulates the stereo needle correctly without cutting one channel out of monaural playback. Instead of using the entire groove for 1 signal, each of the 2 angled walls of the same groove has one channel embossed in them. Hopefully I haven't just completely confused you further... it's an interesting scheme, and a similar philosophy/methodology was later used for FM stereo as well as color TV. There's more to all of this than ever met the eye at the time 😊

​@@MadScientist267 Thanks for this comment definitely helped understand the way sound waves travel like through a diaphragm microphone it just duplicates it. I think I understand now and it's pretty cool how these work because it's the same idea as the automatic transmission with gear reductions and "brake pads".

@@noahwithee7376 Yes, just like in your ear, the diaphragm moves in proportion to the sound wave's pressures, and the coil attached to it moving in a magnetic field (in the case of a dynamic mic) translates this into an electrical signal that represents that vibration. At the speaker, the reverse happens, and a coil receives an electrical signal, interacts with the magnet, makes the cone move, and if all went well, this recreates the air pressure vibrations that the microphone heard during recording. The waves enter your ear, make the eardrum vibrate, and you hear the original sound.

I'm laughing so hard that's LITERALLY where I am at too and I have this machine and been playing with it since I was a kid and that is where I am stuck I don't understand how the groove translates to a precise sound 😂

It's a really good video and covers a lot of stuff like the 'non return spring', which is not understood by many people. However, there are several mentions of vinyl records, which is incorrect. Gramophones never played vinyl records, just shellac based ones. Also, although the section on record manufacturer is very well done, I think it also really refers to vinyl records. Gramophone records would have been recorded on wax, and originally using an acoustic only (no electricity) system similar to how the gramophone replays the record. Well presented and interesting to watch though. Thanks 😀 👍

sorry about my wrong use of vinyl and shellac terms, all my attention kind of went into the working principles. Thank you for watching.

78rpms are made of shellac, not vinyl

sorry about using the wrong terms.. but the working principles are the same.. thank you for your comment.

Old is gold

Why is a modern microgroove 12" vinyl record shown on the turntable of a gramophone that's designed for 78rpm shellac wide groove records? The microgroove record will be immediately destroyed.

Beautifully explained!

thank you so much..

Super my brother for clean my ignorance.Thank you so much to you and the Great mind who invented it.

just awesome and to the point content. more power to you dear.

Humans are so inventive. It is too bad that humans will soon cease to exist

Amazing video thanks so much we love it

Nice: but 'vinyl' is a terrible misnomer. For many years, during the heyday of acoustic gramophones, recordings were made on wax masters: lacquer discs did not come in until at least the 1930s. Pressings were made in shellac: vinyl did not come in until the 1950s/60s.

They already had automatons for ages, but this came up only in 20th century. Odd.

Very good explanation .thanks ❤❤

Playing a microgroove Atlantic vinyl record on a non-electric hand crancked shellac playing horn grammaphone! ha ha ha!

Really good video. Thanks bro

Thank you!

Great content. Keep going.

Thank you so much ❤️❤️❤️❤️❤️❤️ I love you too much ❤️❤️❤️❤️❤️

Also, the record is also shown rotating in the wrong direction in some sections of the video (see 5:10 for instance) - it should be clockwise throughout of course.

amazing graphics

🔥🔥🔥

oh yeah Patti Smith!

por favor, no dejes de hacer esto

Playing a 1970s era Atlantic Records vinyl LP on a gramophone. That's all. Now I see another thumbnail in the related videos of a gramophone sound box turned almost backwards on the arm AND siting on the wrong side of the record. Why is this happening?

GOOD INFO, BUT NOT A FAN OF THE ROBOT VOICE.

Gramophones dont play vinyl records, they play shellac records

They still make gramophones, and the ones currently being produced do in fact play vinyl records.

Is this all AI generated, or just the narrator? I'm guessing it's AI all the way through or there wouldn't be such obvious errors. A human could not have missed the basic method for making old records, only a computer using a more random process would do that. I have to say though, it was pretty good. Keep playing around with different subjects and you'll find the ones AI is better at. If only a computer could edit and proof check, eh?

It is not AI generated. Only the voice is ai generated. The content is written by me. The focus on this video is not about showing every detailed process. I focus more on the general idea and more about the spring motor mechanism. I just want to explain about how gramophone operates. So please don't mind the over simplification of the complex details and terminologies.

Asking if this was AI generated is an insult to my hard work. I learn 3d animation for years to get the quality like this. And I am taking my Mechanical engineering degree because I am very interested in mechanisms and machines . I don't have a working gramophone so I have to find a lot of images just to be able to model the mechanism. I am only using AI generated voice because I am not a native speaker. Please understand if I miss some facts or use wrong terminologies, my videos will only focus on the general working principles and mechanism which fascinate me the most.

It still didn't make sense to me
