I've literally just considered designing a rodent scarer using frequencies above 20kHz and dug out a vintage piezo tweeter and wondering before I start searching if anyone has any experience in this area?
The limited spec for the device is.
So the first issue I have to account for is I need an amplifier which is stable driving a capacitive load.
But what about the drive voltage?
I'm suspicious of the mentioned 400W rating as I can't imagine driving the tweeter at this power and assuming it just means it is suitable for an audio amplifier of 400W rating as a tweeter. It can also be added on to the low and mid-range speakers directly and a cross-over filter is not required.
So in summary what would be the suggested amplifier requirements?
