Abstract: There is provided a method for controlling bass reproduction properties of a multichannel audio system, wherein the audio system has inputs for at least two audio input signals and includes a set of loudspeakers, including at least one bass-capable loudspeaker and at least two high-range loudspeakers, each loudspeaker being associated with a loudspeaker channel. The method includes obtaining impulse responses or transfer functions that represent the sound reproduction properties of each loudspeaker channel at a number of measurement or control positions. The method also includes tuning, when the audio system includes more than one bass-capable loudspeaker, loudspeaker channels of at least two bass loudspeakers to each other so that their sum impulse response has minimum spatial variability, and/or controlling high-range loudspeaker speaker channels to be in-phase with each other and/or with bass-capable loudspeaker channel in a crossover frequency band.

Abstract: The present disclosure relates to an open binaural earphone including a housing, at least one low-frequency speaker, and at least one high-frequency speaker. The housing may be placed on at least one of a head or an ear of a user and not blocking a user’s ear canal, and configured to accommodate the at least one low-frequency speaker and the at least one high-frequency speaker. The at least one low-frequency speaker may be configured to output sounds within a first frequency range from at least two first sound guiding holes through at least two first guiding tubes. The at least one high-frequency speaker may be configured to output sounds within a second frequency range from at least two second sound guiding holes through at least two second guiding tubes. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.

Abstract: A waveguide housing for a speaker assembly. The speaker assembly includes first and second drivers coupled to the waveguide housing where the first driver generates a midrange sound signal and the second driver emits a high-frequency sound signal. The waveguide housing includes a first plurality of sound channels configured to receive the midrange sound signal from the first driver such that the midrange sound signal travels through the first plurality of sound channels and is emitted from the waveguide housing by a first plurality of openings in the waveguide housing. The waveguide housing also includes a second plurality of sound channels configured to receive the high-frequency sound signal from the second driver such that the high-frequency sound signal travels through the second plurality of sound channels and is emitted from the waveguide housing by a second plurality of openings in the waveguide housing.

Abstract: A voice-activated electronic device including a first portion with a first internal surface having a first attachment structure, and a second portion with a second internal surface having a second attachment structure. The first and second internal surfaces have compatible shapes that permit the first and second portions to be moved from a separated position to a joined position, where when the first portion and the second portion are in the joined position the first and second internal surfaces form a nested arrangement. The first and second attachment structures form a secure but separable connection to one another when the first and second portions are in the joined position. The first and second portions are configured to be joined securely and separated through manual human manipulation of one or both of the first portion and the second portion to move the first and second portions between separated and joined positions.
