  • Low frequency sound field in a listening environment
    Patent number: 10893361
    Abstract: The present disclosure provides methods and systems for homogenizing a low frequency listening experience for users in a plurality of locations, such as a plurality of seat positions in a vehicle. An example audio system includes a plurality of woofers configured to output low frequency sound into a listening environment to yield a homogeneous low frequency sound field. Homogeneity of the low frequency sound field in this case is for example spectrally uniform throughout an extended listening space.
    Type: Grant

  • Apparatus for redistributing acoustic energy
    Patent number: 9813805
    Abstract: An apparatus for re-distributing acoustic energy. The apparatus comprises a first concave surface defined as a surface of revolution of a line or curve. This curve of revolution is rotated beyond 230 degrees and thus defines a rather small opening, which has advantages in the frequency response output. Additionally or alternatively, edges of the concave surface may be rounded to provide advantageous effects in the sound output.
