This breakout lets you experiment with sound as a physical vibration. A bone-conduction transducer couples vibration through contact, offering a different interaction from a small speaker playing into the air.

The board combines the actuator with a 3.5mm audio jack and 2.54mm headers for alternative audio connections. Two M2 mounting holes provide a way to incorporate it into an experimental enclosure or fixture.
