  • Patent number: 11818561
    Abstract: Digital audio signal processing techniques used to provide an acoustic transparency function in a pair of headphones. A number of transparency filters can be computed at once, using optimization techniques or using a closed form solution, that are based on multiple re-seatings of the headphones and that are as a result robust for a population of wearers. In another embodiment, a transparency hearing filter of a headphone is computed by an adaptive system that takes into consideration the changing acoustic to electrical path between an earpiece speaker and an interior microphone of that headphone while worn by a user. Other embodiments are also described and claimed.

  • Publication number: 20230077689
    Abstract: A multimedia device having a housing that includes a display screen, two tweeters, two mid-range drivers, and two woofers, which are integrated into the housing. Both woofers are disposed at a first distance from a center vertical axis of the housing in opposite horizontal directions, both tweeters are disposed at a second distance from the center vertical axis in the opposite horizontal directions, and both mid-range drivers are disposed at a third distance from the center vertical axis in opposite horizontal directions. In addition, both the first and second distances are greater than the third distance.

  • Patent number: 10945090
    Abstract: A method performed by an audio system within a room that includes a first loudspeaker that has a first beamforming array and a second loudspeaker that has a second beamforming array. The method obtains a sound program as several input audio channels. The method performs a beamforming algorithm based on the input audio channels to cause each of the arrays to produce a front beam pattern and a side beam pattern when the loudspeakers are close to an object within the room, where the front beam patterns are directed away from the object and the side beam patterns are directed towards the object and the beam patterns contain different portions of the sound program. The method performs a cross-talk cancellation (XTC) algorithm based on a subset of the input audio channels to produce several XTC output signals for driving the arrays when the loudspeakers are far away from the object.
