  • Patent number: 11315541
    Abstract: The disclosed computer-implemented method may include applying, via a sound reproduction system, sound cancellation that reduces an amplitude of various sound signals. The method further includes identifying, among the sound signals, an external sound whose amplitude is to be reduced by the sound cancellation. The method then includes analyzing the identified external sound to determine whether the identified external sound is to be made audible to a user and, upon determining that the external sound is to be made audible to the user, the method includes modifying the sound cancellation so that the identified external sound is made audible to the user. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 11290805
    Abstract: Loudspeakers are described that may reduce comb filtering effects perceived by a listener by either 1) moving transducers closer to a sound reflective surface (e.g., a baseplate, a tabletop or a floor) through vertical (height) or rotational adjustments of the transducers or 2) guiding sound produced by the transducers to be released into the listening area proximate to the reflective surface through the use of horns and openings that are at a prescribed distance from the reflective surface. The reduction of this distance between the reflective surface and the point at which sound emitted by the transducers is released into the listening area may lead to shorter reflected path that reduces comb filtering effects caused by reflected sounds that are delayed relative to the direct sound. Accordingly, the loudspeakers shown and described may be placed on reflective surfaces without severe audio coloration caused by reflected sounds.

  • Patent number: 11290799
    Abstract: An ear unit for stably fitting in an ear includes a first surface facing inwardly toward the ear, a second, opposite surface facing outwardly from the ear and an outer circumferential surface formed between the first and second surfaces. The outer circumferential surface is shaped as a decremental curve. The distance between the ends of the decremental curve is approximately equal to the distance between a first cavity formed under the tragus of the ear and second cavity covered by the lower node of the antihelix of the ear. The first surface is provided with a curvature that provides a contact surface that substantially conforms to the concha, providing an improved attachment, thereby enabling the ear unit to fit closely against the concha when the ear unit is positioned into the ear.
