Abstract: Disclosed is a device and a casing therefor. The device comprises a casing having a back side and a casing opening in the back side; a speaker mounted inside the casing and in communication with the casing opening; and a cover shaped to mate with and to cover the casing opening, the cover having a first nub and a second nub and a speaker opening providing an air channel for the speaker. In the device, the first and the second nubs are located about the speaker opening in a symmetrical pattern; and when the communication device is placed on a flat surface with the side of the casing facing the flat surface, the first and second nubs cause the back side of the casing to be canted from the flat surface to expose the speaker opening to ambient air.
