Or even better, like one of the answer suggested, use an isolation transformer after the divider, which will isolate the output of melody generator from the amplifier. And actually this is how the product...
The circuit uses the popular melody generator IC UM3481. It generates music tones like Jingle bell, Santa clause is coming, Silent night, Holy night, Joy to the world, Rudolph, Red nosed reindeer, Merry Christmas, O come, All Ye faithful, Hark and the herald angel sing. UM 3482 generates 12 music tones. DESCRIPTION The IZ8018 is a CMOS multi Melody IC. The circuit is composed of a 512-word ROM, address counter, tempo and tone Generator, address control circuit, envelope signal Generator, switch control circuit and tone Generator. The IZ8018 has complementary outputs MO, MO for direct piezo drive.

The Ic um66 will produce melodious tone, the output from pin 1 is fed directly to the base of an NPN transistor BC548 via a current limiting Resistor 220 ohms. The transistor will amplify the tone, which is enough to drive the Loud speaker. You check some of our Projects using UM66 IC Water Tank Overflow Alarm Circuit
The main part of this alarm circuit is UM66, it is a melody generator IC. It is very small almost looks like a transistor, it has an inbuilt tone and a beat generator. The IC is programmed to generate certain frequencies.When power is turned on, the melody generator is reset and melody begins from the first note.
