Abstract
An audio device includes a speaker array and a controller for beam-steering audio output by the speaker array to localize sound in different locations in a local area around the audio device. The audio device also includes a microphone array or a set of cameras configured to detect an object, such as a human, in the local area around the audio device. Additionally, the audio device includes a subwoofer for outputting low frequencies. Different speakers are included in different chambers, with the subwoofer also included in a chamber. The audio device opens or closes valve doors separating adjacent chambers to alter audio output. Opening the valve doors allows the audio device to better output low frequencies, while closing the valve door allows the audio device to direct audio output by the speakers to locations in the local area.
