You speak/announce/introduce etc over a microphone, or over a public address system, or over a tannoy.

Thanks for your explanation.

Would "on" be acceptable too?

She introduced him on a microphone.

It's not completely impossible but it doesn't sound natural after "introduced".

He's on the mike now, I'll ask him to introduce you.
She was on the mike for hours. I nearly fell asleep!

On/off can be used as part of a couple of phrasal verbs too:
Get on the mike, it's your turn to speak.
Get off the mike, it's someone else's turn.
