The M348X series IC is a mask-ROM-programmed multi melody generator , implemented by CMOS technology.It is designed to play the melody according to the previously programmed information and is capable of generating 16 songs with 3 instrument effects : piano, organ and mandolin. The device also includes a pre-amplifier which provides a simple interface to the driver circuit. The M3481 series is intended for applications such as toys, door bells, music box, melody clock/timers and telephones.
The following circuit is for testing UM3481. I strongly recommend you to see the datasheet to get more information. You can use UM3482 and UM3483 that produce 12 and 5 melodies respectively. When you press the push-to-on switch, the circuit plays a melody and after playing, it automatically stops. If you press the remote again, the IC plays another melody. In this way, you can play 8 melodies one after another. The melody will repeat if pin 5 is connected to +6V(Pin 16) and will stop automatically if connected to GND(Pin 8). I recommend you to go through the datasheet of UM3481 to know more about it.
