220v alarm clock

Because of the low voltage (1.5V) your options are very limited ..
Maybe you can use an optocoupler, for example the MOC3021 - with the emitter's input forward voltage of just ≈1.2V, and to drive a buzzer of 220Vac use a triac .. see picture below ..

Regards,
IanP

Or you can use appropriate low voltage (reed) relay instead of motor to switch on the buzzer.
