Part one, the transmitter and part two the receiver. The Transmitter of a telephone, lies behind the mouthpiece of the phone. Like the human ear, the transmitter has an 14 eardrum. The eardrum of the telephone is a thin, round metal disk called a diaphragm. When a person talks into the telephone, the sound waves strike the diaphragm and makes it vibrate. Behind the diaphragm lies a small cup filled with tiny grains of carbon. The diaphragm presses against these carbon grains. Low service electric current travels through the grains. This current, comes from batteries at the telephone company. A loud sound causes the sound waves to push hard on the diaphragm. In turn, the diaphragm presses the grains tightly together. This action makes it easier for the electric current to travel through, and a large amount of electricity flows through the grains. When the sound is soft, the sound waves push lightly on the diaphragm. In turn, the diaphragm puts only a slight pressure on the carbon grains. The grains are pressed together loosely. The Receiver is known as an "electric mouth." Like a human voice, it has "vocal cords." The vocal cords of the receiver are a diaphragm. Two magnets located at the edge of the diaphragm cause it to vibrate. One of the magnets is a permanent magnet that holds the diaphragm close to it.The other magnet is an electromagnet. It consists of a piece of iron with a coil of wire wound around it. When an electric current passes through the coil, the iron core becomes

On the contrary, Elena Passarello believes that the whole body participates in the process of making a sound. She makes her point clear about the contest between the diaphragm and the body’s role in producing a sound in the essay Hey Big Spender. She notes that vocal communication can draw out emotions contrary to the conventional knowledge that it was a physical aspect. “Elsewhere in the body, it sends a jolt of adrenaline to quicken the heart and tense major muscles, prepping them for a sprint across the veldt away from danger” (Passarello

These inventions changed the way that people interacted with one another. An example of this is the battery-less radio, created in 1925 by Edward Samuel Rogers. This invention was extremely helpful, as the radio could be plugged into a household electrical socket, opposed to requiring cumbersome batteries. The radio was so well regarded that it was considered “…The set that marks a new era in radio” (Freeman-Shaw, Haskings-Winner 47). This invention not only secured Rogers’ place in the history of communication technology, but also allowed more Canadians to have access to a radio, as anyone with household electricity could use it.
