At first glance, knowing how MP3 players work can be difficult to judge. Systems like Sandisk's Cruzer companion and the iPod look so different, yet have similar functionalities, which only serves to confuse the matter more.
In the most simplistic form, MP3 players function by reading data from a storage unit and then convert the data into an audio form.
When stored on flash drives or hard drives within MP3 players, the software that controls sound output is able to determine what sounds should be made based on what is in your MP3, WAV or WMA format.
As the specifics are rather difficult to comprehend while trying to understand just how do MP3 players work, it is best that you work with the simplified form.
In order to function, MP3 players have several components. It has a CPU, or computer chip, that operates the decoding and software used to run the features and functionalities.
In addition to that, it has the base storage device, which is what allows you to save your MP3s to the device for later access.
Finally, it has a sound output device, which is what converts the audio files into an audible format for your enjoyment. It is the specific combination of these three components that makes certain that you can listen to music whenever and wherever you desire.
In order for your MP3 player to be able to have the songs you want, it also requires a forth and final component. This component, unlike the other three, is not required for normal audio playback.
However, it is required to transfer the songs you want from your computer to your MP3 player and back again. This is usually a fire wire or USB port located on the MP3 player. Some systems require additional cables, while others have the actual jacks directly on the device.
