How work the amplifiers?

When people talk about the amplifiers, normally components or musical equipment are speaking of. But this is only a small representation of the phantom of the audio amplifiers. The reality is that we are surrounded by amplifiers. You can find in televisions, computers, reproducers of all type, and many other devices that use a loudspeaker to produce sounds. We will see in this basic guide, what is what the Y amplifiers do they do since it. The amplifiers can be very complex devices with hundreds of small pieces, but the concept that exists behind them is quite simple. You can take an image clear of how an amplifier works examining the basic components.
                                  
The sound is a fascinating phenomenon. When something vibrates in the atmosphere, it moves the particles that there are around. These particles in the air, as well move the air particles surround that them, taking the pulse of vibration by the air. Our ears capture these fluctuations in the pressure of the air, it translates and them to electrical signals that the brain can process.
The equipment of electronic sound work basically in the same way. It represents the sound like variations of electrical currents. Of a fast form, we can say that there are three passages in this class of sound reproduction:

• The sound waves move a diaphragm in the microphone forwards and back, and the microphone translates east movement in an electrical signal. This electrical signal fluctuates to represent the compression and variations of the sound wave.
• A recorder codifies the electrical signal like a species of scheme - like magnetic impulses in a tape, for example, or as furrows in a vinyl disc.
• A reinterpreta reproducer east scheme as an electrical signal and uses the electricity to move the cone of a loudspeaker advanced back and. This recreates the fluctuations of the pressure of the air originally recorded by the microphone.

As you can see, all the main components in this system are essentially translators: They take the signal in a form they leave and it in another one. In the end, the sound signal is translated to its original format, that is to say, a physical wave of sound.
In order to register all the fluctuations in a sound wave, the diaphragm of the microphone must highly be sensitive. This means that it must be very thin and to move in very short distances. By this, the microphone produces a small electrical charge. This process is viable for the majority of the phases of the process - the current is of sufficient power to use in the recorder, for example, and it is transferred easily by cables. But the final process - to move the cone of the loudspeaker - is more difficult. In order to do this, it is necessary to increase the signal of audio so that it has a greater current, at the same time as it maintains the same scheme of load when fluctuating.
This it is the work of the amplifier. Simply it produces one more a more powerful version of the signal of audio. We will see in the following part of the tutorial, since it makes east process. In order to continue with the guide, it punctures here.
