Abstract:
A directional loudspeaker system has a loudspeaker arrangement configured to generate N audio signals. A time-of-flight sensor arrangement is configured to detect a location of a user. A controller is configured to use information from the time-of-flight sensor arrangement about the location of the user to control the delay such that the N audio signals constructively interfere at the location of the user.
