The transducer is probably highly resonant at the operating frequency.
If you change the frequency, output is likely to be greatly reduced.

I don't think the transducer is so high resonant. At least the specific
one.
On the other hand, I would like to try. Do you know which parts to change?


I'm going to be nasty. What needs changing is your attitude.

Why are you wasting our time? You haven't supplied a manufacturer or a model
number, or a place to find a schematic. Why do you think anyone would have
the knowledge to suggest a specific change for an unknown product?

Furthermore, the answers I and others gave were "reasonable" in the context
of the question you asked and the overall design of such products.

If you know so much about the unit, modify it yourself.

To be a bit more diplomatic , the OP did supply photos of the PCB.

But, someone would have to take a fair amount of time to try to figure
out which parts control frequency from looking at it. "Blue caps"
don't mean anything - one has to trace the circuit to determine what
the components do.

If the OP would do that and post a schematic, or even a partial
schematic, then someone should be able to help.
