is rather difficult and needs an active circuit for useful power distribution.
Power supplies A and B need to have the same Vout; Iout maximum can be different
Brilliant for someone who has a real problem and knows what a Piezo looks like which is not this small woofer with a tiny magnet that is good for 30 W before it melts.Current-mode-controlled supplies sometimes offer current
sharing. We designed our POL DC-DC chips to do "one
wire current sharing" (plus a little fiddling with local set-
components & pin strapping).
If your supplies are current mode controlled and you feel
up to the task of figuring it out and rewiring the "slave"
to use current-controlling error voltage from one, to drive
the "back end" of the other, and can do it clean, you might
get proper operation.

No I don't have I am a beginner but I have made some simple electronic projects already.The optimal current sharing design depends on each supply’s tolerance to backdriving without damage. Do you have a CC/CV Lab supply to find out?
I already assembled NE555 buck boost converter so I can generate about 60 Volts and 5 Amperes from +12 Volts power supply. It should be aboout 300 Watts of power.A bridge amplifier, either linear or class D, needs at least 50 VDC supply to output 35 V sine signal. Even if you drive the speaker with square wave, you still need 35 VDC + some margin for amplifier voltage loss.
The other point is that a piezo horn doesn't actually consume 150 or even 300 W because it doesn't have 8 or 4 ohm impedance. These are purely fictive numbers.
Hard to believe.I already assembled NE555 buck boost converter so I can generate about 60 Volts and 5 Amperes from +12 Volts power supply. It should be aboout 300 Watts of power.
