A Richthupe may contain at least one group of multiple speakers or sound emitter. The sound emitter may be a sound signal [dt respectively. "And audio signal"] send to a same frequency. A processor can control a relative phase difference, and a relative gain difference between each tone signal on the basis of a certain direction. The Richthupe may be positioned on a vehicle. The desired direction may be based on a direction indicated by a driver who drives the vehicle direction on external environmental factors on the vehicle dynamics or other factors.
