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.
Claims20
A transducer assembly, comprising:
- a lower housing;
- an upper housing;
- a first audio transducer disposed in the lower housing, wherein the first audio transducer is arranged to output sound in a first direction;
- a second audio transducer disposed in the upper housing and oriented toward the lower housing, wherein the second audio transducer is arranged to output sound in a second direction different than the first direction, and wherein the second audio transducer is configured to output sound in a second frequency range greater than a first frequency range associated with the first audio transducer;
- a curved waveguide between the upper housing and the lower housing, wherein the curved waveguide is configured to re-direct sound output via the second audio transducer away from the lower housing;
- and
- a plurality of pillars disposed on the curved waveguide that support the upper housing above the curved waveguide.
4 more elements
A transducer assembly, comprising:
- a first audio transducer, wherein the first audio transducer is arranged to output sound in a first direction;
- a second audio transducer, wherein at least one portion of the second audio transducer is disposed above the first audio transducer, wherein the second audio transducer is arranged to output sound in a second direction different than the first direction, and wherein the second audio transducer is configured to output sound in a second frequency range greater than a first frequency range associated with the first audio transducer;
- and
- a plurality of pillars, wherein the plurality of pillars is disposed between the first audio transducer and the second audio transducer, and wherein the plurality of pillars supports the second audio transducer.
