Piezo speaker amplifier?

hello everyone I need help
I damaged accidentally a very loud piezo and I need to rebuild it
The piezo was driven from mcu pin connected to a npn ztx614 transistor and a kind of a transformer (I’ve attached pics of it) witch I broke
Can you help me find this part or something similar so i can take again this loudness I had?
It’s use was like amplifier I think
Thank you !

More than likely some form of audio transformer normally used for impedance matching.
Just what values would depend on the rest of the circuit.

No, you would have to know the specifications of the original. And those would be difficult to even guess.
 
What device is it from? Give as many details as you can so maybe someone can find a schematic and/or some specs.
