Abstract: An acoustic lens system comprises one or more speakers and a substrate. The speaker comprises a driver capable of receiving an audio signal and a wave forming member in communication with the driver and having a sloped surface. The speaker is adapted to abut the substrate. In use, the driver causes translation of the wave forming member in response to the audio signal. The translation of the wave forming member causes the sloped surface to generate an audio waveform that extends in a direction divergent to the direction of translation. The speaker also generates forces against the substrate so that a ripple wave is propagated along the substrate. The propagation of the ripple wave is projected perpendicularly at a location on the substrate to generate a sound wave from the substrate. The sound wave generated by the ripple wave and the divergently extending wave from the wave forming member intersect at a position away from the speaker thereby creating an immersive sound experience for the user.
