Audio is reductive into electrical signals will be the voice signal a device, restore authenticity as a performance evaluation of the speakers will be important standard. Active speakers with power amplifier is the speaker system. Put the power amplifier and the speaker system into an organic whole, can be directly with general of the audio source (such as sound with listening, CD, DVD player, etc) is tiein, form a plete set of sound system. And mini speaker is a simple active acoustics, this paper mainly introduces the mini audio the structure, function, and working principle, which is mainly posed of TDA2822 chip of integrated amplifier circuit to form. Itself has the power supply voltage range wide, static power consumption is small, can a single power use, price is low wait for an advantage. Is a monly used to family sound system, stereo, and other electronic system CD player, easy to carry, applicability. Key words: Audio, TDA2822, transistors, electrolytic capacitors目 錄前言…………………………………………………………………………………………11. 總體設計方案………………………………………………………………………2
