Phase plug and acoustic lens for direct radiating loudspeaker |
| abstract |
A phase plugs or acoustic lens improves the directional audio performance of a loudspeaker. Application of the improved directional audio performance to a sound system in a listening area improves the performance of the audio system. Configurations of acoustic lens or phase plug which include both symmetrical and asymmetrical features to provide an improved frequency response and directivity are presented. The application of phase plugs or acoustic lens to a loudspeaker may provide improved sound in a listing location, for example, in a vehicle. |
