    Abstract: A multi-way speaker array is disclosed that includes rings of transducers of different types. The rings of transducers may encircle the cabinet of the speaker array such that the speaker array is rotationally symmetric. The distance between rings of transducers may be based on a logarithmic scale. By separating rings of transducers using logarithmic spacing, denser transducer spacing at short wavelengths is achieved while limiting the number of transducers needed for longer wavelengths by spacing them in larger and larger logarithmic increments. Transducers with overlapping frequency ranges may be used in the speaker array to avoid initial dips or shortfalls in directivity for corresponding beam patterns.

    Abstract: An audio system is described that includes one or more speaker arrays that emit sound corresponding to one or more pieces of sound program content into associated zones within a listening area. Using parameters of the audio system (e.g., locations of the speaker arrays and the audio sources), the zones, the users, the pieces of sound program content, and the listening area, one or more beam pattern attributes may be generated. The beam pattern attributes define a set of beams that are used to generate audio beams for channels of sound program content to be played in each zone. The beam pattern attributes may be updated as changes are detected within the listening environment. By adapting to these changing conditions, the audio system is capable of reproducing sound that accurately represents each piece of sound program content in various zones.

    Abstract: An earphone comprising an earphone housing having a wall comprising (1) a front side that joins (2) an end portion in which a primary sound output opening is formed, which joins (3) a face portion in which a secondary output opening is formed, which joins (4) a back side which joins the front side and encloses a driver, wherein the primary output opening is dimensioned to output sound generated by a diaphragm of the driver contained within the earphone housing into the ear and the secondary output opening is dimensioned to vent the ear to a surrounding environment, and wherein the primary output opening and the secondary output opening face different directions.

    Abstract: Embodiments described herein may take the form of a textile product having one or more regions of reduced density. These reduced density volumes may form one or more features in the product. For example, the reduced density volumes may have better acoustic transmission properties, optical transmission properties, flexibility, and the like. Sound transmission may be enhanced not only in terms of clarity, but also overall range. That is, certain audio frequencies that the textile may normally block when in an unaltered state may pass through a textile having reduced density or reduced density regions.
