Schematics for a custom DIY bark repellent device

Job Description:

I need help creating a custom DIY bark repellent device. It can be based on Arduino, Raspberry or pure electronics - Raspberry and Arduino being the best as they can be easily updated or programmed.

Anything I can find on the market are small toys without the much required power.

It has to use larger loudspeakers - not the tiny kind you see in any bark repellent

It has to allow change of frequency (as in adjusting for a specific dog/animal).

From what I understood it has to emit ultrasonics around 20kHz-25Khz (in case of dogs) so it is not a such complicated device but I need someone to think about all these aspects and compatibility of the electronic pieces.

I have very good coding skills and some basic electronics knowledge so I will be able to provide feedback and help with anything I can.

In the end I need to have the list of pieces to buy and schematics to assemble and tune it myself (on my side).

Skills: Arduino, Electronics, Microcontroller, Product Design, Raspberry Pi
