Bookshelf Active Speaker
Due to the beautiful sound effect of the single player, it has gradually become a pet in the hands of many young friends. Especially with the advancement of technology and the improvement of people's appreciation ability, many single players have some functions of small combo speakers. Many audiophiles often use the single player as the sound source. But the disadvantage of the single player is that the output power is small, so many young people and friends have bought speakers with amplified functions, that is, active speakers as the power expansion of the single player. The active speakers sold on the market are expensive, so you can make a pair of active speakers yourself, which can save costs and increase your ability to experiment. Taking into account the difficulty of production and the cost should not be too large, this set of active speakers, mainly integrated circuit TDA2822, supplemented by broadband high-sensitivity speakers, its small size and beautiful sound. This set of small active speakers only has the function of sound amplification. In order to reduce the complexity of the function control, the volume control is controlled by the volume potentiometer of the single player. It is better if the single player can have three-band tone equalization and automatic rewinding function.
