US Patent 7778431 Sound enhancing stands for portable audio devices

Stands for a portable audio device include a housing and a mounting member. The mounting member is configured to couple the audio device to the housing at a location selected to reflect sounds generated by a speaker of the audio device away from the housing. Stands may include a resonator cavity in the housing with an outlet opening extending to the resonator cavity from an exterior surface of the housing and a volume of the resonator cavity and a size of the outlet opening extending thereto may be selected to provide a desired resonant frequency response of the resonator cavity to amplify sounds generated by the speaker of the audio device.
