The Surface Transducer (Small) turns almost any surface into a speaker. Instead of a traditional cone, the voice coil is attached to a pad that conducts vibrations into whatever surface it's pressed against — tables, walls, enclosures, or panels.

Simply connect it to an audio source and place it firmly against a flat surface to produce sound. The transducer excites the surface, effectively turning it into a speaker diaphragm.
