I have a dog bark control unit that is not powerful enough.
Will this work if my amp handles 20khz?

In theory, yes, but … your scematics is too simple – lack technical details – to say how well it will work.
A piezo speaker does not draw current the way a regular speaker does, so advice you add a 25-50 ohm resistor in series with the speaker after the 40 Watt amp to prevent either the speaker or the amp from being burned out.
Without knowing how your "bark control" unit works, it is impossible to say if it will still put out sound at desired level and frequency when you connect an amp's input to it. Advice you add a resistor of about 10Kohm in series with each of the two wires that you connect the "bark control" speaker to the amp with, just to avoid mismatch and failing unit. |

I wonder what kind of trees need bark control. |

| I think folks that can't train their dogs use a "bark control" collar to shock the heck out of them whenever they make noise. I saw a dog once that his owner had used that technique, but also had small kids. Every time the kids would shriek the dog would get shocked. The animal was worthless as a pet, scared of people, and would run and hide when he saw any! The "family" took him to the pound where they had to put him down. |
