Low-cost stereo audiphone

If the utility model discloses a low-cost stereo audiphone, including adapter A, resistance R1, triode V1 and chip IC1, said adapter A's one end connecting resistance R2 and electric capacity C1, adapter A's other end connecting resistance R5, resistance R6, electric capacity C2, potentiometre RP1's stiff end, potentiometre RP2's stiff end and chip IC1's pin 4. The utility model discloses the audiphone adopts the stereo audio power amplifier of TDA2822 type as the core component, and the signal conditioning who accepts the adapter becomes to have the stereo signal output of simulation of certain phase difference, and the constant flow element has been added to the while circuit, has reduced the interference of power to the signal, therefore this circuit has the advantage of simple structure, with low costs, stable performance.
