Embodiment Construction

[0017] Several embodiments described with reference to the accompanying figures will now be explained. Although numerous details are set forth, it is understood that some embodiments of the invention may be practiced without these details. In other instances, well-known circuits, structures and techniques have not been shown in detail in order not to obscure the understanding of this description.

[0018] figure 1 A top view of an audio system 1 according to an embodiment of the invention is shown. The audio system 1 may comprise an external audio source 2 , an audio receiver 3 and a loudspeaker array 4 . Audio system 1 outputs sound program content into a room or listening area 6 where one or more intended listeners 5A and 5B are located. Listeners 5A and 5B may be seated at various positions in listening area 6 and audio receiver 3 may adjust the sound output by speaker array 4 according to the commands and preferences of listeners 5A and 5B, as will be described in more ...

Abstract

An audio system that adjusts one or more beam patterns emitted by one or more loudspeaker arrays based on the preferences of users/listeners is described. The audio system includes an audio receiver that contains a listener location estimator, a listener identifier, and a voice command processor. Inputs from the listener location estimator, the listener identifier, and the voice command processor are fed into an array processor. The array processor drives the one or more loudspeaker arrays to emit beam patterns into the listening area based on inputs from each of these devices. By examining the location, preferred usage settings, and voice commands from listeners, the generated beam patterns are customized to the explicit and implicit preferences of the listeners with minimal direct input. Other embodiments are also described.

Description

[0001] This patent application claims the benefit of the earlier filing date of US Provisional Patent Application 61 / 907,946, filed November 22, 2013. technical field [0002] The present invention describes a system and method for configuring and adjusting a beam pattern output by a speaker system in response to voice commands. Other embodiments are also described. Background technique [0003] Loudspeaker arrays create beam patterns that focus sound in specific directions. For example, groups of transducers in a loudspeaker array may be individually and individually driven according to different parameters and settings, including delay and energy level, to generate one or more beam patterns in the listening area. Beam patterns focus sound on specific objects or individuals in the listening area. [0004] Although beam patterns allow sound to be focused in different directions and / or at specific objects or individuals, configuring beam patterns is often a complex and labo...
