Building elements with sonic actuation

A toy construction system includes a plurality of interconnectable building elements; a control system that generates an electromagnetic signal; a vibration speaker including a moveable permanent magnet; and a support building element mechanically linked to the permanent magnet of the vibration speaker. The vibration speaker includes a coil that is moveable relative to the permanent magnet. One or more of the coil and the permanent magnet vibrate in a manner that is based on the electromagnetic signal. The vibration speaker also includes a sound producer that is mechanically linked to the coil to vibrate with the coil as the coil vibrates. The coil vibrates relative to the permanent magnet to produce an audible sound, and the permanent magnet vibrates to cause the support building element to vibrate and animate interconnectable building elements linked to the support building element.
