Abstract (en)
[origin: EP0119277A1] A reverberation sound generator is provided for use as a warning generator for giving a warning to the driver of an automobile, for example. The reverberation sound generator has a capacitor (14) connected in series with a power supply (11), a pair of diodes (15, 16) and a pair of resistors (17, 18) connected in series with the capacitor, and a sound generator circuit (19) connected between the pair of diodes and the pair of resistors. A sound generation command switch (20) is joined in series with the diodes and resistors. There is a circuit for discharging the capacitor. The capacitor can be controlled in its charging and discharging in response to closing and opening of the sound generation switch. When the capacitor is charged and discharged, the sound generator circuit produces reverberation sounds, respectively.
