Mp3 is a player that can play music files. It is mainly composed of a memory (memory card), a display (LCD display), a central processing unit [MCU (micro controller) or a decoding DSP (digital signal processor).

An MP3 player is actually a function-specific small computer. In the small body of the MP3 player, it has MP3 player memory (memory card), MP3 player display (LCD display), MP3 player central processing unit [MCU (microcontroller) or MP3 player decoding DSP (Digital Signal Processor), etc.

The microprocessor is the "brain" of the player, which is used to accept the playback control selected by the user, and displays the currently played song information on the liquid crystal display, and then issues an instruction to the data signal processing chip to accurately process the audio signal. . The digital signal processor first decompresses the MP3 file with a decompression algorithm, then converts the digital information into waveform information using a digital-to-analog converter, then the amplifier amplifies the signal and sends it to the audio port, and finally we can pass the earphone connected to the audio port. Then we heard beautiful music.



At the same time, we can use our own data cable (USB) to connect with the computer, and import your favorite audio files into MP3 through the network, not only to listen to music, but also to carry out necessary English listening training. In short, it is the crystallization of wisdom in this informationized world.
