* โทรศัพท์ในยุคบุกเบิก เกร็ดคร่าวๆ

* Phone pioneer era. Outline of tips, "Graham Bell" about the ideas invented the handset has the hypothesis that one day. Bell noticed that the sound is caused by vibration of piano wire. Therefore, it's probably the wire conductor Audio from one place to another. With this principle, he had an idea to create a transmit sound waves, is leading to the flat, which has a magnetic sheet metals are. A wire coil and the magnet round again, and when the sound waves cause vibrations of metal. Vibration causes Electric current in a wire around a magnet, and then flows through the wire, another one where the receiver and the receiver will have a similar duty to change the electricity back into the system. And here's the dude is the hypothesis of work, pick up the phone "Graham Bell". วิวัฒนาการของระบบการสื่อสาร จากการใช้นกพิราบ ควันไฟ หรือว่าใช้มนุษย์เดินทางส่งข่าวสาร ถึงวันนี้ เราต่างปฏิเสธไม่ได้ว่า โทรศัพท์นั้นมีประโยชน์และอำนวยความสะดวกให้เราได้มากมายขนาดไหน สรุปคือ คุณอันอเนกอนันต์ของ “โทรศัพท์” นั้นก็มีอยู่มาก แต่ถ้าหากนำไปใช้ผิดวิธี…โทรแทงหวย โทรแทงบอล รึว่าโทรจีบภรรยาคนอื่นเค้า เมื่อโดนสังคมลงโทษ จะไปพาลโทษคนประดิษฐ์อย่าง “เกรแฮม เบลล์” ไม่ได้นะครับท่าน…

* In pioneering
models of rough, "Graham Bell" about the idea to invent the theory that the phone was available that day, Bell noted. The piano sound is caused by the vibration of the string. Therefore, it seems to be a conductor wire. Audio from one place to another, even with this principle he thought created the pass. To conduct sound waves to flat sheet metal with a magnet. Near and wire coiled around the magnet again. When sound waves vibrate the metal. The vibration causes Electrical current in a wire around a magnet. Then flows through the wire lines, which connect to the receiver and the receiver are similar to convert electricity to return to sound again. And this is me Theoretical work by Telephone, "Graham Bell," The evolution of communication systems. Smoke from the pigeons that used to send humans to today, we can not deny that. The phone is useful and convenient for us how much is concluded. Are you a twenty of "telephone" that are more common. But if used the wrong way ... Lottery, call, call, call out my wife read other people. When society gets punished To bully blaming invention, "Graham Bell," I can not ...

* the phone in the pioneer era
.The specifics of the idea. "Graham Bell." the idea innovate theory handset can be นั้นมีอยู่ that one day the bell noticed that. Piano sound due to the vibration of the wire. Therefore, wire are more likely to be the main character.
.
.With this principle, so he thought establish pass. As a conductor to metal flat plate sound waves which is magnetic. Near the wire coil and magnetic round it. When sound waves make metal vibration vibration cause.It flows through the wire, one which the receiver and the receiver will be เครื่องคล้ายๆ. Also changed electricity back to the sound again. And there it is.
