The Telephone - How It Works

[@dratelectasis]

Amazing how these old videos explain things so much clearer

[@I-Libertine]

Yes! This is the phone. You pick it up and talk into it.

[@brycef7130]

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

[@foreignerJas_Gaming]

Cuz ppl that time could mess with social medias less

[@LordBeezleDwarf]

They werent trying to over complicate their explanations in an attempt to try and make u feel ull never understand

[@thepsychedelicaxolotle5020]

Don't underestimate your elders

[@melaniec1074]

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.

[@fmphotooffice5513]

The film respects the young viewer's intelligence and ability to focus on the subject. No need to "entertain" to maintain attention. From here the interested student will imagine questions for the teachers, etc. It might even begin a life-long interest in electronics.

[@BetterB502]

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”.

[@barbezph]

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

[@raimeyewens7518]

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. 🤷🏻‍♀️

[@sam-001]

This is god gifted , scientists had got this properties by experimenting again and again. First time i had also can't believe😊😮

[@johnf817]

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.

[@hyperbitcoinizationpod]

surf's up, dude

[@fl04]

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

[@kfl611]

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.

[@LauraoAirylea]

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.

[@AnkurProductionFilm]

This video helps to understand the old technology of telephone.

[@harjitsingh-jn1vu]

I am delighted that I found this very informative video, might use it for project.

[@mtnfreestyle1899]

Crazy it doesn't have more views

[@JaredPaxton]

I love learning things like this. Very neat!

Very informative, thank you very much

[@john_smith1471]

Interesting to see a then very modern 1962 telephone but on a manual exchange, so no dial service.

[@kono9460]

So much better than attempting to understand the wikipedia article

[@zb1423]

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.

[@PushpavalliR22BCI017]

Amazing explanation

[@ranjeetmore6913]

Very nice video sir, and thank you so much

[@DanielSilva-ml5zs]

Great explanation. 👏🏽

Thank you all for your comments! We're excited to announce that the National Communication Museum will be opening its doors on 21 September 2024, after overcoming COVID-related delays and build complications (which are all resolved now). If you or anyone you know is in Melbourne, we’d love to see you there! We're located at 375 Burwood Rd, Hawthorn. Let us know what kind of content you'd like to see on our channel, and we'll do our best to deliver.

[@geniusguycannotlie6620]

Amazing

[@ds99]

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.

[@andrewhogan6628]

Because the bell would only ring if you put DC current through the line. You can have a "connected" (closed) line (circuit) but not inject any current.

[@SupremeST25]

Ingenious!

[@madhavyadav5905]

Amazing explanation!

[@QueeeeenZ]

from what year is this movie?

[@QueeeeenZ]

oh it's 1962

[@gameyord7182]

I would say arroumd 1900

[@BetterB502]

@@gameyord7182 lol 1900? They didn’t even have this type of technology to record videos.

[@BetterB502]

If you watch til the end it says 1962

[@CreeperGirl-cb2eu]

Now I know how the Telephone Work ❗

[@tct-14isharabihan91]

Thank you very much❤

[@StealthFB22]

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 😂😂

[@AYVYN]

Headphones still use Armature drivers

[@garyj.2424]

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

[@alexjohnson1411]

Beauty in vintage

[@KhedrAli-q4s]

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.

[@AlessandroZir]

amazing!! 🤸🤸🤸🤸💥🙏🙌❤️

[@zoidelux]

I am confused about the “DC transformer”. I thought transforming DC power is impossible? Im guessing theres more to this transformer than wire coils?

[@Amine-gz7gq]

your voice will vary the resistance of the microphone, creating an alternating current.

[@niczano]

Meucci is the inventor of the telephone, not Bell, as the US Congress also recognized.

[@dharmvijaysingh1596]

Amazing, I was searching this from very long time.

[@freshgino]

What’s the year this was produced? You should put in the title!

[@thomaspaine7098]

Late 40s early 50s based off the phone in the beginning

[@dandyhighwayman]

1962 based off the large text in the credits saying, "1962"

[@apurvadange8423]

watching this in 2024

[@thebancfamily8645]

Wow

[@BRAKEHORSEPOWER0]

[@tertia0011]

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.
