The Telephone - How It Works

- Have you ever wondered how your voice can travel thousands of kilometres, instantaneously? The transmission of speech long predates Alexander Graham Bell’s telephone of 1876, as makeshift instruments such as pipes or cones were used to project a voice over greater distance. But the telephone as we know it was a more ambitious device; it sought connection across towns, continents and oceans.

Amazing how these old videos explain things so much clearer
Yes! This is the phone. You pick it up and talk into it.
Ya I just got done watching some 9 year olds talk threw a tin can lol wish they did a little better but it worked
Cuz ppl that time could mess with social medias less
They werent trying to over complicate their explanations in an attempt to try and make u feel ull never understand
Don't underestimate your elders
As old as this film is, it still explained the dynamics of the basic phone system quite well. It's actually the first one I have found to explain it in a way I can understand.
Tho he’s explaining everything so clearly, so much more understanding than it would ever be explained now I still don’t understand how it’s possible for our voices travel in real time through wires and/or “the air”.
Just using Alternating Current. alternating currents and magnets are real friends!
They work together in order to make things work. Just think at an electromagnet, when you power it up it turns and gets on, make this many times in a second and you created a movement from a signal. Then as explained in the video, you can transform this signal into voice just with a diaphram! Or a bell ecc
I asked my husband this last night. Even with the old phone we had in the 80’s I don’t understand it. How did my voice travel through wires across the states while many others were on it also? Or when he was in another country several years ago. How did my voice travel through my cell phone to him? I guess I’m just slow minded lol. 🤷🏻♀️
This is god gifted , scientists had got this properties by experimenting again and again.
First time i had also can't believe😊😮
Literally everything is electromagnetic energy/waves. The same way we see a red square, for example. because the electromagnetic waves bounce off of it in the exact pattern into our eyes in order to display a red square. Voice and radio waves go into our ears at the exact frequency/pattern to create what we hear. God gave us the electromagnetic spectrum and it is the basis for almost everything.
You'd think we've evolved since the 60s and yet videos advertising clear explanations on youtube is just annoying stock music and someone who doesn't really know what he's talking about. this is just amazing
Wow, never thought it was possible to explain a complex concept so simply without ever uttering the words "like" or "subscribe". They did discuss ringin the bell tho. But if Meat loaf taught me anything, 2 outta 3 ain't bad.
This was well presented. I thought it was older than 1962. I got a flash back, when the film started, it reminded me of watching films at school and you heard that scrachy sound before the sound of the film started. It's been many decades since I have heard that.
It's the sound of the needle hitting the vinyl record and audio gaps before speech of his voice is captured during recording. It's amazing how much of our world was analog before digitization took over. It's incredible that the majority of humans (myself included) have no idea how the technologies around us function.
I love learning things like this. Very neat!
This video helps to understand the old technology of telephone.
This old video is 10x preciser than collage professors today
Looks like your English professor wasn't too great n' all 🤣
@@quackuza English is very funny language today you learn from me ..
@@quackuza lol you typed that like a hillbilly you are one to talk 😂
I am delighted that I found this very informative video, might use it for project.
Thank you very much for this gem,
Ingenious!
Crazy it doesn't have more views
Very informative, thank you very much
Great explanation. 👏🏽
Very nice video sir, and thank you so much
Amazing
Amazing explanation!
Very interesting, thank you.
Interesting to see a then very modern 1962 telephone but on a manual exchange, so no dial service.
amazing!! 🤸🤸🤸🤸💥🙏🙌❤️
Thank you very much❤
Imagine how the people that made this informative video would think if they got to see the first wireless landline, first cell phone and first smartphone 😂😂
Headphones still use Armature drivers
Very best best best best best ......
Switching theory is fascinating.
Brilliant video explaining sound waves and what was done to improve them using electricity. One thing I don’t understand is regarding the bell. If the bell is always connected to the line even when the line is not in use, wouldn’t it be consuming and wasting a lot of electricity? How does hanging up signal that the connection has been ended if the bell is still connected to the line? Wouldn’t that cause the system to think a connection is still there? Especially where this is all done over 2 wires? The same two wires used for bell ringing and speech.
should have had something like this when I was in school
So much better than attempting to understand the wikipedia article
Beauty in vintage
Amazing, I was searching this from very long time.
from what year is this movie?
oh it's 1962
I would say arroumd 1900
@@gameyord7182 lol 1900? They didn’t even have this type of technology to record videos.
If you watch til the end it says 1962
Amazing, right now everything is controlled by a computer and I just found out that everything was really and totally manual and it's need a human controls. But definitely we started in a simple and basic before, until we become complete
Wow
Meucci is the inventor of the telephone, not Bell, as the US Congress also recognized.
why don't we just use the force of the sound waves to change the lenth of the wire so it will make different resistance depending on what we say.
What’s the year this was produced? You should put in the title!
Late 40s early 50s based off the phone in the beginning
1962 based off the large text in the credits saying, "1962"
I am confused about the “DC transformer”. I thought transforming DC power is impossible? Im guessing theres more to this transformer than wire coils?
your voice will vary the resistance of the microphone, creating an alternating current.
watching this in 2024

I had opportunity to see ancient 'step by step' switched telephone exchange in operation before its decommission. Lots of clicking & whirring, unlike modern digital exchanges which are exceptionally dull & boring by comparison. Man & dog exchange - dog prevents man from meddling with exchange equipment. Man is there only to feed the dog.

Telephones Are Really 🤔 Inspiring!
Bell wasn't the inventor of the telephone 🙈🤦🏻♂️
