Small bed listening system circuit

Published:2011/5/3 2:46:00 Author:TaoXi | Keyword: Small, bed listening system

The small bed listening system circuit is as shown. This system uses two TDA2822M and has the features of small, simple and good sound, particularly enhanced the bass, so it is very suitable for the fans who live in the dormitory. IC1, IC2 are the stereo power amplifier integrated circuit TDA2822M, the two-channel power amplifier circuit is composed of IC1, the audio signal gets into the ICl through the resistance R1, R3 and double potentiometer RP1-1, RPl-2, the amplified audio signal promotes the speaker BL1, BL2 to work. IC2 (BTL circuit) constitutes the bass amplifier, switch Sl controls it. Because the BTL circuit power dissipation is high, you need to add the heatsink on IC2. In addition, because there is no low-pass filter installed on the bass amplifier, so in use, you need to use the audio tone control circuit machine or use the small bass speaker to enhance the bass.   (View)
