Abstract

An electronic device that provides dynamic equalization in a directional speaker array is described. Based at least in part on audio content and an acoustic radiation pattern associated with a second electronic device, the electronic device may determine drive signals for a set of drivers. Then, the electronic device may adjust the drive signals for at least a subset of the set of drivers based at least in part on a distortion margin in at least the subset of the drivers, where the distortion margin is based at least in part on the drive signals, a distortion threshold of at least the subset of the drivers and a volume setting. Next, based at least in part on the adjusted drive signals, the electronic device may output, using the set of drivers, the sound corresponding to the audio content.
