  • Patent number: 12108207
    Abstract: Audio device transducer arrays and associated systems and methods are disclosed herein. In some examples, the audio device can comprise a housing including a baffle and an acoustically reflective plate spaced apart from and facing at least partially toward the baffle, such that the baffle and the plate define an opening therebetween. The audio device can further comprise an array of electroacoustic transducers disposed within or surrounded by the baffle and configured to emit acoustic waves toward the opening. The array of transducers can be configured to produce acoustic waves having a frequency of about 1.5 kilohertz (kHz) or greater.

  • Patent number: 12035101
    Abstract: A playback device comprises an electroacoustic transducer; an acoustic waveguide in fluid communication with the transducer; and a housing delimiting an opening of the waveguide, the opening extending around an axis passing through the transducer. The opening may have a radial distance from the axis that varies with an azimuthal angle about the axis. An acoustic path length within the waveguide, between the transducer and the opening, is substantially constant and independent of azimuthal angle about the axis.
