Road safety electronic sound system for quiet vehicles

摘要

Road safety electronic sound system for quiet or silent vehicles while circulating in order to alert others about their presence. The system comprises a capsule (1) in the approximate shape of a cylinder, the lateral surface thereof comprising a partial mesh grille (5) and a connection terminal (3). The capsule comprises a pair of push buttons (2) on one of the bases thereof and a microcontroller (6) inside. The microcontroller is connected to: a power supply (4); the pair of push buttons (2) for programming the functions of the microcontroller; the connection terminal (3) for connecting it to an outer housing (9, 26, 38); a speaker (7); and, a movement sensor (8).In this way, the microcontroller by means of the speaker is able to emit a permanent sound, which can be turned off,when said microcontroller detects, by means of the sensor (8), movement in the surroundings of the electronic system itself.
