Classification: CPC H | IPC H

Claim 14:
15. A playback device comprising:
an elongated body defining an outer perimeter that includes a forward surface and a rear surface;
an audio transducer carried by the body and configured to output sound along a first axis; and
a waveguide in fluid communication with the audio transducer, the waveguide comprising:
a sidewall extending circumferentially around the audio transducer, the sidewall having a first end adjacent the audio transducer and a second end adjacent the outer perimeter; and
an opening defined by the sidewall, the opening having a larger area at the second end than at the first end;
wherein a rear portion of the sidewall is more steeply angled with respect to the first axis than a forward portion of the sidewall,
wherein the audio transducer and the waveguide are configured such that, during playback of audio at 2000 Hz via the audio transducer, acoustic energy along the first axis is greater than acoustic energy along a forward axis by between 10 dB and 50 dB, and
wherein the forward axis is horizontally angled with respect to the first axis by between about 60 to 80 degrees.
