A portable electronic device can include a housing defining an aperture and a display positioned in the aperture. The display and the housing can define an internal volume and a speaker assembly can be positioned in the internal volume. The speaker assembly can include a speaker enclosure sealed to the housing within the internal volume, the speaker enclosure and the housing defining a speaker volume, and a speaker module in fluid communication with the speaker volume, the speaker module including a diaphragm positioned at an aperture defined by the speaker volume, the diaphragm defining multiple ridges.

Portable electronic device

A portable electronic device includes several speakers spaced apart from one another on opposite sides of the device. An audio processor attenuates high frequency portions of a first audio signal and a second audio signal to provide a processed first audio signal and a processed second audio signal. An audio router directs the first audio signal to only a first speaker on a first side of the device, and directs the second audio signal to only a second speaker on a second side of the device. The audio signals may be directed according to an orientation of the device.

Stereo and filter control for multi-speaker device

A portable electronic device includes at least four speakers spaced apart from one another. An audio processor attenuates a high frequency portion of a left audio signal and a right audio signal to provide a processed left audio signal and a processed right audio signal. An audio router directs the left audio signal to only a first speaker, the right audio signal to only a second speaker, the processed left audio signal to a third speaker, and the processed right audio signal to a fourth speaker. The audio signals may be directed according to the orientation of the device. The cutoff frequency for attenuating the high frequency portion of the audio signals may be responsive to the orientation of the device. In other embodiments, the high frequency portion of the audio signals may be decorrelated to produce signals with high frequency portions for all speakers.
