The KD-156 music IC can play the Ding-Dong and birds singing these two sounds. Its sounds are pure and sweet and it is a special IC to be used to make the electronic doorbell. The electronic doorbell circuit made by using this IC is shown in the picture. The A, B ports in the picture are two trigger signal input ports. A is positive pulses trigger port and B is negative pulses trigger port. S1 is button switch and S2 is selection switch. When the S2 is set in position shown in the picture, by pressing the S1 the A port would be connected with the power positive source. And the IC would be triggered to output the birds singing signal. By amplification through VT1, the loudspeaker would play the birds singing sound. If the S2 is set to the other position, when pressing S1, the B port would be connected with the power nagetive source and would get negative pulses trigger signals.
