Bookshelf active speakers

Single player has gradually become a favorite of many young friends due to its beautiful playback effect. Especially now with the advancement of technology and the improvement of people's appreciation ability, many single player has some functions of small combination audio system, and many audiophiles often use single player as the sound source.

But the shortcoming of single player is that the output power is small, so many young friends buy speakers with sound amplification function, that is, active speakers, as the power expansion of single player.

The active speakers sold on the market are very expensive, so making a pair of active speakers by yourself can not only save money, but also improve your hands-on experimental skills.

Taking into account the difficulty and cost of production, this set of active speakers is mainly based on the integrated circuit TDA2822, supplemented by a wide-band high-sensitivity speaker. It is small in size and produces beautiful and pleasant sound.

This set of small active speakers only has the function of amplification. In order to reduce the complexity of function control, the volume control is controlled by the volume potentiometer of the single player. It would be better if the single player could have three-band tone balance and automatic tape turning functions.
