Abstract
A sound-producing device includes a housing having a front and a top, a first electro-acoustic transducer facing from the front of the housing, a second electro-acoustic transducer facing from the top of the housing, and a third electro-acoustic transducer facing from the top of the housing. There is at least one processor that is configured to, during audio playback, generate a first array using the first and second electro-acoustic transducers, the first array providing a left height component of the audio playback, and generate a second array using the first and third electro-acoustic transducers, the second array providing a right height component of the audio playback.
