  • Patent number: 11451902
    Abstract: Aspects of the subject technology relate to electronic devices having speakers with vented resonators. A vented resonator may have a resonator chamber and a channel that fluidly couples a front volume of the speaker with the resonator chamber. A vent such as a barometric vent may be disposed in a wall of the resonator chamber that separates the resonator chamber from the back volume of the speaker. The barometric vent may thus allow airflow from the front volume to the back volume via the resonator chamber, and prevent fluid flow from the front volume to the back volume via the resonator chamber.

  • Patent number: 11166090
    Abstract: A loudspeaker in which a plurality of speaker drivers is jointly tasked with reproducing sounds. The plurality of speaker drivers is arranged on the loudspeaker so as to achieve a desired sound effect at a listening position. The plurality of speaker drivers is arranged in an arcuate arrangement or in a sinusoidal arrangement. The desired sound effect may be facilitated or enhanced by modifying the timing of sounds emanated from each of the plurality of speaker drivers. Alternatively, sounds may be sent to each of the plurality of speaker drivers substantially simultaneously. The sound effect achieved may be a time-alignment effect such that the sound arriving at the listening position is time-aligned to maximize constructive interference between the various speaker drivers of the plurality of speaker drivers. Alternatively, the sound effect achieved by other implementations may be a progressive kick in sound waves moving along the arcuate or sinusoidal arrangement.

  • Patent number: 11102583
    Abstract: An audio power output circuit provides a pair of output signals to an audio output transducer that has two different voice coils. Using a measured or predicted position of the voice coil assembly with respect to the transducer's magnetic field, a processing circuit generates the pair of signals such that a first relationship between a first one of the pair of output signals and an audio input signal and a second relationship between a second one of the pair of the output signals vary with the position of the voice coil. Offset in the Dynamic Mean Position (DMP) can be compensated for without adding low frequency or direct current components that compromise the dynamic range of the transducer. The efficiency, acoustic output power and/or linearity of the acoustic output of the transducer may be optimized by tailoring the first and second relationship to a particular target performance.

  • Patent number: 10555059
    Abstract: A bracket assembly is used to secure a housing to a support structure such as a post, wall or ceiling. The bracket assembly includes an inner bracket, an outer bracket and a connector. The inner bracket is configured to be mounted on the support structure separately from the outer bracket, and the outer bracket is configured to be quickly mounted on the inner bracket. The outer bracket and connector are joined by a ball and socket joint. Angular adjustment of the ball relative to the socket is made prior to mounting of the outer bracket on the inner bracket, and the desired orientation is maintained using a clamping assembly. The bracket assembly includes sealing features that prevent moisture from entering the assembly.

  • Patent number: 10516147
    Abstract: Implementations of a battery pack with reduced magnetic field emission are provided. In some implementations, the battery pack may be configured to reduce and/or eliminate the magnetic field normally generated while electrical current is being drawn from one or more cylindrical-steel electrochemical cells (e.g., AA batteries) by a connected electrical device. In some implementations, each electrochemical cell of a battery pack may include a conductive sleeve comprised of four conductive strips that are separated from the electrochemical cell by a thin insulating layer of material. In this way, the conductive sleeve provides a return path for electrical current that minimizes the loop area between the electrochemical cell and the conductive sleeve thereof. In some implementations, the four conductive strips of a conductive sleeve may be equally spaced 90 degrees apart and/or positioned longitudinally on a cylindrical-steel electrochemical cell, separated therefrom by the insulating layer of material.
