Abstract: A height channel speaker with an integrated acoustic reflector to reflect sound off of a ceiling down to a listener. The acoustic reflector compensates for thin transducers by creating a virtual image of the real sound source outside the speaker enclosure. The focal point of the acoustic reflector is controlled by modifying the curvature of the reflector surface. The transducer is mounted on an inclined plane to radiate sound in a rear-upward inclined direction. The acoustic reflector is mounted on the same inclined plane so that the radiant axis of the transducer is directly incident on the acoustic reflector surface. The sound is projected towards the ceiling in a forward, upward-inclined direction to reflect off the ceiling and down to the listener. The speaker can be acoustically occluded from the listener by a panel to which the speaker is attached.
