Abstract
An appliance for personal use such as a toothbrush, an oral irrigator, a shaver, or a kitchen machine, with a driving mechanism constructed as an electric motor and a control stage that supplies energy to the electric motor. When the electric motor is off, the control stage supplies the electric motor with energy adapted in terms of duration and/or amplitude. The electric motor, when off and in its capacity as an electroacoustic transducer, emits at least part of that energy in the form of audible signals.
