How Does a Home Stereo Amplifier Work?

Whenever people talk about "amplifiers", they are normally referring to a home stereo amplifier or musical equipment. However, this is only a minimal part of the huge scope that an audio or home stereo amplifier encompasses. There are numerous types of home stereo amplifiers. Amplifiers can essentially be seen in computers, televisions, speakers, portable CD players, and other devices that require a speaker in order to produce great sounds. Sound and music are an amazing and magnificent phenomenon.

Whenever there is a vibration that occurs in the environment, the particles surrounding it move along with it. These air particles will move as well the air particles that surround them, transporting the vibration pulse through the air. Your ears receive these fluctuations in the form of air pressure and convert them into electrical signals and codes that your brain can process.

 Electronic sound equipments, like a home stereo amplifier, work in the same basic method. It mirrors sound as a changeable electric current. Ultimately, there are 3 steps and processes of this type of sound reproduction:

 1. Sound frequency waves stimulate a microphone diaphragm to swing back and forth, and the microphone converts this swinging motion into an electrical signal. This electrical signal rises and falls in order to represent the refractions and compressions of the sound wave.

2. A voice recorder encodes electrical signals as a pattern through some sort of medium. For example, they can be translated into magnetic impulses on voice tapes or as grooves in a record piece.

3. A tape deck player retakes this actual pattern as an electrical signal and utilizes this electricity to swing or move a speaker cone in a back and forth movement. This will reproduce the air pressure oscillations that were previously recorded by the microphone.

 As you have read and understood, all the primary components in this electrical system are translators. They encode the signal in a specific form and convert it into another. The sound signal is then translated back into its previous and original form, which is a physical sound wave. To register and recognize all the minute pressure fluctuations occurring in a single sound wave, the microphone diaphragm must be tremendously sensitive. This means that its size should be very thin and that it only moves a short distance.

As a result, the microphone creates a small but adequate electrical current. The method by which the microphone produces small electrical current is usually fine for most of the process' stages. This electrical production, for instance, is strong enough for the usage of a voice or tape recorder and the signals are easily transmitted through electrical wires.

 However, the final step, which is pushing the speaker cone in a back and forth movement, is considered more difficult. To do this, you must boost the audio electrical signals so it will have larger currents while maintaining the same fluctuation pattern or charge. This is the main job of a home stereo amplifier as well as any other type of amplifier. It basically produces a more dominant version of the traditional audio signal. Amplifiers are intensely complex sound devices, composed of hundreds of tiny electrical pieces; however, you will be able to grasp a clearer picture on how they work if you exert a bit of effort in examining its basic properties and components.
