摘要： The present invention concerns a drive circuit (11) for driving an oscillator (3). The drive circuit (11) comprises a first inductor (L D ) comprising a first terminal and a second terminal; an electrical energy source (13) connected to the first terminal; and a switching circuit connected to the second terminal and to the oscillator. The switching circuit is configured to operate at least in an off state, where it is configured not to feed electrical energy to the oscillator (3), and in an on state, where it is configured to feed electrical energy to the oscillator (3). The first inductor (L D ) is arranged to store energy in its magnetic field when the switching circuit is in the off state, and, when the switching circuit is in the on state, the switching circuit is arranged to use at least some of the energy stored in the magnetic field to deliver a surge of current from the electrical energy source (13) to the oscillator (3).

摘要： Le dispositif électronique est prévu pour la génération d'un avertissement sonore ou d'une musique. Il comprend une bobine ou inductance et un vibreur acoustique muni d'un condensateur relié en série avec la bobine. Lors de la mise en fonction du dispositif électronique, le vibreur acoustique génère l'avertissement sonore ou la musique. Le dispositif électronique comprend en outre dans une boucle de rétroaction, un circuit dérivateur relié à un noeud de connexion entre la bobine et le condensateur, pour dériver le signal provenant du condensateur, et un comparateur pour comparer un signal de dérivée du circuit dérivateur avec une tension de référence. Le comparateur fournit un signal de sortie à la bobine pour amplifier le signal sur le condensateur, afin que le vibreur génère au moins un avertissement sonore.
