For the first time, a sound reflection system is used in a rodent shocker. This makes it possible to achieve 360 degrees of radiation.This SecoRuet high-performance rodent shocker develops and manufactures in Germany protects your car from all the unpleasant marten damage that can have serious consequences. A cone with a convex design is arranged via a piezo loudspeaker with a Nawimran membrane, which has the same shape and diameter of the Nawimemran. The convex curved cone is arranged at a certain distance above the center axis. The height of the cone and also the distance are adjusted for the narrow-band radiation frequency and for the sound pressure. By this arrangement, the system generates a high sound pressure and an all-round radiation of 360 degrees. A high-performance ultrasonic generator with C-MOS output stage drives the piezo loudspeaker. The piezo speaker produces an ultrasonic sound of 22.5 kHz +/- 1 kHz, which cannot be heard by humans. The sound level conceals martens a
