Abstract (en)

[origin: DE10137529A1] The sound generator has at least one electronic sound signal source (12i), which includes a module (14) that supplies the sound frequency, e.g. a multivibrator with timer, and a module (16) that sets the sound loudness. The source is connected to a loudspeaker driver circuit (22) via a circuit (18) that combines the output signals from the two modules. The two modules may be formed from a micro-controller (24) or integrated peripheral components of a micro-controller.
