摘要

Sound waves (3) penetrate the vehicle's bodywork and drive martins away as they get near the vehicle. Integrated in a mobile telephone (1), a sound/ultrasound transmitter (5) can be activated manually or automatically. It is also an effective weapon against aggressive dogs. Power can be raised or lowered depending how the dog behaves.
