An audio device may be configured to have multiple modes of operation. The mode of the device may be associated with a particular geometric configuration of the device, such as by swiveling an arm of the device and/or changing the orientation of the device with respect to gravity and/or a surface (e.g., table) on which the device rests. The device may determine the appropriate state based on the current geometry, and based on the state may tune the device for a particular operation suited for that geometry. For example, different signal processing parameters may be applied, different microphones may be enabled and disabled, and/or different acoustic conditions may be provided (for example, different modes of a passive radiator) based on the mode.
