Yep, we're going with the sound-wave idea. Where I'm stuck is with what's producing it. Not a megaphone, megaphones are for people to shout into and enhance their own voices; it doesn't produce its own sound, which is what this machine needs to do.
However it looks, it might have a speaker component, but it won't look like a plain speaker box or a boombox. We're probably talking Highly Advanced Carefully Constructed Machine here for the express purpose of shoving large objects around with the Power Of Sound. Make it a boombox-like design and people will think that scientists just took a regular boombox, turned the volume up really loud, and said they'd created a very intricate new machine.
... Actually, that'd be kind of funny. The Rocket Scientists make some amazing new technology and everyone thinks they're bluffing because it looks like just a normal boombox. Think you can design an ultra-high-tech boombox? Without all the normal buttons and slots for CDs/cassettes/radio, since this item's going to be a soundwave-inducer exclusively, not a music-producer.
Then again... maybe a few normal radio buttons. It can double as a radio. Maybe I can replace the Poké Flute with the Strength boombox, figure out how to edit the sound so that using the Poké Flute plays that unused Rocket song from R/S/E, and say you can use the boombox to wake up your Pokémon due to the sheer volume of the device. What a Rocket thing to do, wake up Pokémon by blasting their eardrums out.
But mostly, boombox shape, boombox speakers, but not the other dials or buttons or antenna and such.
