This article will discuss one of the most important inventions to complete the phone since its creation, the answering machine.

The telephone was invented to a person able to call someone and talk to them. For the person who made the call, so they are doing their part already completed. But what about the person at the reception? They should keep the phone until the call to be completed andHere's the problem with this system. That's not exactly infallible. The other party may be in the shower or while the house and fail, leaving the person to call frustrated. I can not even leave a message for the withdrawal.

The answering machine rescue.

Even if the answering machine is a relatively recent invention, brings us back to something that was created in 1898 to return. That year, a Danish telephoneengineer named Valdemar Poulsen patented what he called a telegraphone. This was the first practical machine for magnetic recording of sound and playback. It was actually capable of recording telephone conversations. On a pro, has recorded the changing magnetic fields produced by a sound. The magnetized wire was then used to reproduce the sound.

However, it was not until 1935 that we had the first automatic answering machine was invented by Mr. Willy Muller. Firstanswering machine was ridiculously huge three meters high. It was very popular among the Jews were not allowed to answer the phone on Saturday.

But responding to the first sale in the United States was the Ansafone, which was created by Dr. Kazuo Hashimoto invented for Phonetel. He figures Japan would be the first to reach our answering machine used commercially for the first.

The contributions are Phonetel not the end of our progressresponders, however. Casio actually created what is called the first commercially viable car telephone in 1971. They created what is called the telephone answering device (TAD), which was the model 400, now the Smithsonian Institute.

Even in 1971 we gave her answer was also the first phonemic model 400. He worked a bit 'different from the machine from Casio, in the sense that weighed 10 pounds and took up to twenty messages on reel to reel tape. He came witha headset that allowed users to retrieve private messages.

The first half of ADP was given by the same person who gave us the first Ansafone. It was invented in 1983 and was given patent number 4,616,110 of the United States and was admitted camera phone.

Other improvements and additions have been made to answer that now include what is known as voice mail, which was actually created before the patent Digital DAT (number of patents4371752), but became popular only after the fact. Voicemail was invented in 1979 by Gordon Matthews. He sold the first system to 3M.
