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.
Claims18
A playback device comprising:
- an audio transducer oriented in a first direction aligned with a center axis;
- and
- a housing surrounding the audio transducer, wherein the housing comprises:
- an opening that corresponds to a path of an arc, wherein the path of the arc subtends an angle less than 180 degrees with respect to the center axis;
- and
- an acoustic waveguide arranged to provide an acoustic path between the audio transducer and the opening.
