A device for deflecting a light beam in response to an audio input signal includes a hub member, a mirror flexibly attached to the hub member, a magnet connected to the mirror, an electromagnetic coil, and a low pass filter. The electromagnetic coil is positioned adjacent the magnet for producing an electromagnetic field in relation to a received audio input signal when energized, thereby urging the magnet and the mirror to oscillate with respect to the hub member in relation to the audio input signal. The low pass filter filters out audio input signal frequencies that would cause the mirror and the magnet to naturally resonate. The mirror may be attached at an offset angle that causes a light beam striking the mirror to be deflected angularly away from an axis of rotation passing through the hub member.
