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: A directivity pattern generator for producing sound patterns using a modal architecture is described. The directivity pattern generator may include a beam pattern mixing unit, which defines sound patterns to be emitted by an audio system in terms of a set of frequency invariant modes or modal patterns. The beam pattern mixing unit produces a set of modal gains representing the level or degree each of the predefined modal patterns is to be applied to a set of audio streams. Modal filters may be used to modal amplitudes that compensate for inefficiencies of the each modal pattern at low frequencies. The directivity pattern generator may include a modal decomposition unit for generating driving signals for each transducer in one or more loudspeaker arrays based on weighted values for the modal gains/amplitudes.

Abstract: Examples of speaker assemblies are described. A speaker assembly according to some embodiments may include a speaker enclosure with a first opening (e.g., a speaker opening) and a second opening (e.g. a bass reflex port), a speaker unit mounted to the enclosure at the first opening, and an acoustic damping mechanism mounted to the enclosure at the second opening. The acoustic damping mechanism may be a dual-layer mesh screen including a first mesh with a first acoustic resistance (AR) for providing acoustic damping, and a second mesh with a second AR lower than the first AR. The second mesh may be nearly acoustically transparent and may serve to increase the stiffness of the first mesh. The first mesh may be bonded to the second mesh, and the dual-layer mesh screen may be coupled to the bass reflex port for reducing noise associated with turbulence at the port.
Abstract translation: 描述扬声器组件的示例。 根据一些实施例的扬声器组件可以包括具有第一开口（例如，扬声器开口）和第二开口（例如，低音反射端口）的扬声器外壳，在第一开口处安装到外壳的扬声器单元和声学 阻尼机构安装在第二开口处的外壳上。 声阻尼机构可以是包括具有用于提供声阻尼的第一声阻（AR）的第一网格和比第一AR低的第二AR的第二网格的双层网格屏幕。 第二网可以几乎是声学透明的，并且可以用于增加第一网格的刚度。 第一网格可以结合到第二网格，并且双层网格屏幕可以耦合到低音反射端口，以减少与端口处的湍流相关联的噪声。
