Directional Acoustic Radiating Device

A directional acoustic radiating device, comprising:

• an assembly configured to attach to a micro-mobility device, the assembly comprising
• a first acoustic driver that is acoustically coupled to a first passive directional device so as to radiate acoustic energy into the first passive directional device, wherein the first passive directional device comprises an opening in a perimeter of the first passive directional device that extends along a length of the first passive directional device and through which acoustic energy is radiated to an environment to provide a direction of maximum radiation of the first passive directional device, and
• a second acoustic driver that is acoustically coupled to a second passive directional device so as to radiate acoustic energy into the second passive directional device, wherein the second passive directional device comprises an opening in a perimeter of the second passive directional device that extends along a length of the second passive directional device and through which acoustic energy is radiated to an environment to provide a direction of maximum radiation of the second passive directional device;
• and
• a controller that is configured to manipulate a phase of the acoustic energy radiated by the first and second drivers.
