小型立体声放大器TDA7052

小型立体声放大器，低功耗，更少的设备，IC TDA7025的主要设备。操作的电路，分为左，右分割的信号通过电容C1耦合，C2是一个可变电阻VR1调节桥式放大器的电源供应商IC1的输入信号的强度。IC2，对信号进行放大，留下的扬声器 - 右。

电阻R1，R2设定的输入阻抗的电路中，电容器C4，当前的滤波器来平滑和C1降低噪音，和高频率的，从而从电源到地。它有助于稳定电路。

Small stereo amplifier,low power, less devices, IC TDA7025 is the main equipment. Operation of the circuit, the signal split into left and right through the capacitor coupling of C1, C2 is a variable resistor VR1 adjusts the strength of the input signals to bridge amplifiers power suppliers IC1-. IC2, serves to amplify the signal up, drive out the speakers left – right.

Resistors R1, R2 set the input impedance to the circuit box,The capacitor C4, the current filter to smooth and C1 reduce noise, and high frequency, resulting from the power supply to ground. It helps to stabilize the circuit.

该电路电源：6伏电池或电池，只有4瓦的输出功率为1.5瓦8欧姆扬声器的声音小电视，收音机，卡带播放。这是一个光或声音。没有人被禁止。只有一个耳机插孔，或的手机变为可用。

This circuit power supply: 6-volt battery or batteries, only 4 watts of output power up to 1.5 watts at 8-ohm speakers to the sound of small TV, radio, cassette player. It’s a light or sound. No one was banned. Only has a headphone jack or the phone becomes available.

如何建立这个项目，
