Abstract
An audio accessory comprising one or more speaker units may be used to provide audio output for a media device such as a tablet computer, smartphone, and so forth. The speaker units may be affixed to various surfaces, such as an acoustic panel which serves as a portion of a cover for the media device. The acoustic panel may act as an acoustic radiator which is driven by one or more of the speaker units. When not in use, a pair of the speaker units may be joined together for compact storage.
