Embodiment

[0021] Example: such as figure 1 As shown, it is a system structure diagram of an MP3 player, which is composed of a main control module, a decoding module, a playback unit, a power supply unit, a storage module, a communication module and a human-computer interaction unit. Stable operation and low power consumption are all STM32F103VET6 single-chip microcomputers. The power supply unit, decoding module, storage module and human-computer interaction unit are electrically connected to the corresponding pins of the single-chip microcomputer. The decoding module adopts VS1003 audio decoding module, playback unit and power supply unit They are respectively electrically connected to the corresponding pins of the audio decoding module. The power supply unit can choose three power supply modes. The three power supply modes include 5VDC power supply for the main control module and 2.5V DC power supply and 3.3V DC power supply for the decoding module. Among them 5V DC is supplied from ...

Description

technical field [0001] The invention belongs to the field of electronic products, and in particular relates to an MP3 player. Background technique [0002] With the rapid development of microelectronics technology, embedded products have been popularized rapidly with their natural human-computer interaction interface and rich multimedia processing capabilities, and have achieved great success. [0003] MP3 is a high-quality music compression standard, the amount of data compressed by MP3 can be reduced to 1 / 12 sound quality without much loss. Due to the small amount of data and the high-quality playback effect of MP3 music, it soon becomes a digital product integrating audio playback and data storage and is deeply loved by people. [0004] The entertainment function of the MP3 player on the market is single, and the download and transmission of data are through special data lines and interfaces, and the data transmission speed is slow. Nowadays, various electronic products ...
