Claim 11:
12. A method of reflecting sound waves for immersive audio content having height cues from a ceiling of a listening environment, comprising:
directing sound waves from a transducer of a speaker along a radiant axis to an acoustic reflector attached to the speaker, wherein the acoustic reflector and the transducer are mounted on an inclined plane such that the radiant axis of the transducer is directly incident on an inner surface of the acoustic reflector, wherein the acoustic reflector reflects, shapes and focuses sound radiation incident from the transducer towards the ceiling in a forward-upward-inclined direction to provide the height cues of the immersive audio content, wherein the speaker includes a first side and a second side joined by the inclined plane, wherein the first side has a lower vertical height than the second side, and wherein a barrier provides acoustic occlusion from a listener facing the second side such that direct sound transmission from the transducer to the listener is reduced.
