Building elements with sonic actuation

A toy construction system 100 includes a plurality of interconnectible building elements 151; a control system 130 that generates an electromagnetic signal; a vibration speaker 110 including a moveable permanent magnet 145; and a support building element 165 mechanically linked to the permanent magnet 145 of the vibration speaker 110. The vibration speaker 110 includes a coil 127 that is moveable relative to the permanent magnet 145. One or more of the coil 127 and the permanent magnet 145 vibrate in a manner that is based on the electromagnetic signal 125. The vibration speaker 110 also includes a sound producer 160 that is mechanically linked to the coil to vibrate with the coil as the coil vibrates. The coil 127 vibrates relative to the permanent magnet 145 to produce an audible sound, and the permanent magnet vibrates to cause the support building element 165 to vibrate and animate interconnectible building elements 170 linked to the support building element 165.
