Product Introduction:
1.Model: AKE-1
2.Operating Voltage:DC 4.5-5V
3.PCB Board:42*31mm
4.Circuit Principle: stereo sound audio signal is input by J2; since left/right channel circuit
are completely symmetric, and we take one of them as example in here to analyze signal process;
audio signal is sent to C5 capacitor through VR1 volume potentiometer;R2 resistor is input to U1
chip the 10th pin; after internallt amplified by U1, it will be output to loudspeaker through U1 the
14th pin and 16th pin. J1 is power input port, C7 is power filtering capacitor.

Notice:
1.The limit operating voltage of the chip is 5.5V;if uses battery for power supply,the total
voltage should not be over 5.5V,or it will cause damadge to the chip.
2.Since there is great gain in the digital volume control of the chip,please don't let input
signal too large to cut the amplitude limit when increasing its volume,or it will lead to
sound distortion or even destroy the chip.
