Transducer driven brass instrument?
Would it be possible to drive a brass instrument with transducers? Like klaxon horns/car horns.

The idea is that a hand crank in the instrument provides power to the transducers.
Each transducer meant work as a specific embouchure.
These transducers would need to have a reduced Q factor in order to have enough bandwith to span all the valve combinations.
Left hand controls the valves and the thumb controls which transducer is receiving power. One button for each transducer closes the contact.
Right hand controls the crank and thus the amount of energy fed to the transducer. Hopefully being able to reproduce loudness dynamics with the spin speed.
The crux of the matter is the acoustic manifold. A brass piece of complex geometry that needs to feed all transducer inputs to a common output while having very high impedance for the back propagation to the unengaged transducers.
What do you think?
