Circuit Description The Bluetooth Speaker includes below main components：IC2 (HX6001), IC3 (CYT8117), IC4 (TX3012), U2 (LM358), U5(bluetooth module), CN1(mini USB socket), JK1(headphone jack), K1(power switch), S1(button), S2(button), S3(button), LED1(light diode), LED2(light diode)，BAT(battery). Bluetooth circuit: The IC3 and L8, C14, C2, C25 constitute a 3.3Vvoltage supply U5 circuit (utilizing a 16MHz oscillator), which will receive and decode the audio signal and then via the C3, C4 input to U2, after U2 magnification and high-pass filter output to IC4 power amplifier, and then by IC4 power amplifier output to the speaker.Through the S1, S2 control U5, make U5 I/O, PIO4 control IC4 increase volume; AIO3 control IC4 reduced volume.S3 control U5, make its control music play/pause. LED2 for bluetooth indicator. AUX audio circuit: JK1 for external audio input port AUX, audio through input to the U2 C1 high-pass filter, and then by IC4 power amplifier output to the speaker. Charging circuit explanation: CN1 mini USB socket of the input DC5V supply IC2 first constant current 310 mA, again constant pressure to lithium battery charging 4.2 V.LED1 for charging indicator .
