Abstract
An acoustic lens may improve the directional audio performance of a loudspeaker. Application of the improved directional audio performance to a sound system in a listening area may improve the performance of the audio system. The acoustic lens (or phase plug) may be acoustically opaque and partially fill the cavity formed by the loudspeaker cone. The acoustic lens may provide an improved frequency response and directivity. The improved loudspeaker may provide an improved listening location, for example, in a vehicle, a room or a concert hall.
