Gravity, the Hironao Tsuboi-designed speaker from Meizu does everything that a normal speaker does, i.e. plays sound through it and also connects with your phone via wifi, and it also stays upright. This is not much of a feat for the average speaker, but for Gravity, it's pretty impressive considering the cantilevered design that makes it appear as though it is floating in midair.
