MP3 Player/Dishwasher/Body Image Scanner

Ultrasonic cleaning devices exist, but they only seem to be able to clean small objects such as jewellery and model parts. MP3 players also exist, but they only seem to be able to play sound well below ultrasonic pitch. They also tend to be fairly quiet. But audio sampling has been around a long time and is usually well into the ultrasonic range, although it doesn't often seem to have been used for ultrasound. I presume it has been done but I haven't Googled.

It seems to me that there should be a device which can do all three. It's a general media player rather than just playing MP3s. Unlike other audio players, its volume can be turned up to deafening levels, though not while the earbuds are attached. It has preloaded ultrasonic audio files at around 40 kHz and a washing up bowl with a jack plug. When you wish to do the washing up, you plug the washing up bowl into the media player, fill it with water and washing up liquid, turn it on and it vibrates the gunk off your dishes before draining. If you're pregnant or have something interesting going on inside your body, take the media player, cover it in gloop and press it against the appropriate part of your anatomy, and it will scan the interior of your body ultrasonically and produce an image on its screen.

Finally, you can boost the bass and use it for something else.
