Changing Societies Ways Since March 10th, 1876

When the telephone was first made, only the upper class could afford it because the service and material used to make it was very expensive. The problem with this is that only some people could afford it. However, for the wealthy it did increase communication.

Telephones shaped the American work force. When the telephone was invented it changed jobs for office workers. Every workplace today has a phone. The telephone has improved security and helped in emergency situations. With the telephone it has made it easier and faster to talk to people. The phone has made people lazier so most people will call to receive their food (instead of picking it up or making their own). The phone has also affected the way we do stuff, for example; we do business over the phone a lot now - instead of them having to come in and converse in person they can just conference by phone. In some situations you could argue that phones are both bad and good; there are many topics for both good and bad. For example it is faster to make calls. But you can take what people say in the wrong way over the phone.

So basically you could say the telephone has changed society's behavior because of the development of communication with one another. As the years go by, the telephones have advanced as well; changing our mindset and thinking in ways we would have never thought of. A good thing that the telephone had done in the past was help children/adults with their education even when they didn’t know how to read and write.

How Wired Telephones Work

In a wired phone there are four cords two that go to the speaker and two that go to the microphone. Once they are out of the phone itself they go to a duplex coil which is just two coils in a casing that transmits electricity. After they go through the coils two cords go to the keypad so you can dial you numbers and two go to the hook switches throughs are wrapped around a little cylinder and then they attach four more wires two attached to the hook switch and two hooked up to the ringer the the other end of the cord is plugged into the wall jack. Once in the wall jack there are a cable that goes to the phone box which is outside of homes in those boxes there are a series of wires that gives off electrical waves that travel through copper wires to other peoples boxes and into the wall jack to the wires and when the person picks the phone up it answers the call.

The waves are electrical and they send analog signals which are copies of your voice when you talk in the microphone. If your electrical signal is at a high amplitude the analog copy will be a high amplitude as well because it make an exact copy of it. When you speak into the microphone you sound waves make a thin piece of plastic move and then it makes a magnet move and when the magnet move it creates electrical wave. It then travels to the wire. After that it then has a mirror effect and makes the exact copies. However, when it gets to the speaker of the other end of the call it make another magnet move and it turns back to sound waves.

History of the Telephone


Alexander Graham Bell is the reason we have telephone technology today. Although of course if he had not been so interested in inventing there may have been another creator. He patented the electric telephone in 1876. (Interesting fact: he had to defend himself 600 times because claims of other individuals being the first inventor of a telephone).

Switchboard Operators

Switchboard Operators were next, at first they were runned by telegraph boys but where soon replaced by young women (as they had proven more friendly and dependable than the boys). This is where people would call the operators and then state who they needed to call. They would then connect you to that persons line. The bad thing about this was they had to listen to you conversations to know when to disconnect the line. This created jobs for many because of the increasing number of calls.


In the 1880's the Hand Cranked Wall was created.


In the 1890's the Candlestick (on the right) and the Cradle phone (on the left) were created.


In the 1914's the Candlestick Rotary (on left) was created and in the 1920's the Desktop Rotary (on right) was created.


In the 1960's the Touchstone (on left) was created and in the 1970's the Wall Touchstone (on right) was created.


In the 1980's the cordless phone had been created. In the 1983's the mobile/cellular phone had been created. In the 1990's the candy bar phone had been created.

2000 - Present

The sliding/qwerty keyboard, bluetooth, touch screen, and iPhones had been invented.

Past to the Future

As you can see by now, there has been many types of telephones but also slight modifications have been made.

How the Physical Landscapes Affect Wired Telephones

The physical landscape affects how the power lines/telephone lines will be located. For example, if you lived in a rocky area it would be difficult to put the telephone lines up. The bad thing about having power lines is that if there were a lightning storm it could strike the pole and cause it to have an electric outage. Also if there had been a tornado or a very strong wind it could blow and tear the towers done. However, it gives birds a place to porch.
