Abstract
Various embodiments are directed to an audio system. The audio system may include a first audio device that includes a casing that houses a speaker and an internal waveguide. The internal waveguide may be configured to direct sound from the speaker to ambient air outside the casing. In some embodiments, the casing of the first audio device may be configured such that, when the first audio device physically engages or is otherwise coupled to a surface of an object (e.g., when the casing is placed on a surface of a table), an external surface of the casing forms, in conjunction with the surface of the object, an extended waveguide. The extended waveguide may be longer than the internal waveguide, which may provide several benefits to the operation of the first audio device versus when the first audio device is not coupled to the surface of the object.
