This was possible in the past with expensive devices that could turn sheetrock walls into speakers. Reaction was mixed. Now enter Tunebug, a device that turns surfaces into speakers for less than a hundred dollars. I have not tried one but I’ll be happy to review this device because the idea is promising. Imagine plugging your iPod/MP3 player in to a big speaker. It’s portable too. Yes you can turn almost any flat surface into a panel speaker (they suggest cardboard boxes or anything else hollow for best results.) Turn it up!
