First Claim
Patent Images
1. A tunable, vehicular directional horn, comprising:
- a horn mounted on a vehicle, the horn including at least one cluster of audio emitters, each of the audio emitters configured to emit;
at least one audio signal; and
a processor configured to;
define a direction of focus of a horn sound based on sensor data, the horn sound being a composite of the audio signals,define a relative phase difference and a relative gain difference between each the audio signals, in accordance with the direction of focus of the horn sound.

Abstract
A directional horn may include at least one group of a plurality of speakers or audio emitters. The audio emitters may each emit and audio signal at a same frequency. A processor may control a relative phase difference and relative gain difference between each audio signal, based on a determined direction. The directional horn may be positioned on a vehicle. The determined direction may be based on a direction indicated by a driver controlling the vehicle, external environmental factors, vehicle dynamics, or other factors.
