Abstract

The system has a hybrid transducer (1) controlled by an electro-acoustic equipment (8) i.e. common interface, that assures distribution of power between a piezoelectric transducer (2) and a magnetic transducer (3) according to a required function e.g. approach preventive sound signal function, realized by approaching vehicle audible system, alarm function and sound warning function. The hybrid transducer and the equipment are integrated in single housing. The piezoelectric transducer is coaxially mounted on a front face of the magnetic transducer.
