The CW9561 analog sound integrated circuit is a IC which can play the alarm sound, whistle sound, police cars sound and guns sound. Its typical application circuit is shown in the picture. In the circuit shown in picture (a), when the switch S2 is set separately at the position of A, B and C, this circuit would play the alarm sound, whistle sound and police cars sound. When the switch S1 is closed, the circuit would play the guns sound no matter which position the switch S2 is set. In the circuit shown in picture (b), the switch S2 is a double-pole four-throw switch. When it is set to one of the stages, the circuit would separately play the alarm sound, guns sound, ambulances sound and fire-fighting vehicle sound.
