Interactive device

An interactive device, comprises:

• a supporting base comprising a supporting surface, a bottom surface and an internal space formed between the supporting surface and the bottom surface, wherein a plurality of electrical interfaces formed on the supporting surface;
• a circuit board disposed in the internal space, wherein a circuit control unit disposed on the circuit board and electrically connected to each of the plurality of electrical interfaces;
• and
• a first functional element comprising a first functional surface, a first mounting surface, and a plurality of first side surfaces that surround the first functional surface and the first mounting surface.

An interactive device, comprises:

• a supporting base comprising a supporting surface, a bottom surface, an internal space formed between the supporting surface and the bottom surface;
• and
• a first mounting region, a second mounting region, a third mounting region, and a fourth mounting region defined on the supporting surface;
• wherein an area of the first mounting region is equal to an area of the third mounting region and smaller than an area of the second mounting region, and the area of the second mounting region is equal to an area of the fourth mounting region and larger than the area of the first mounting region.
