Abstract: The invention relates to a method for controlling the intensity of the massaging motion of a massage device including at least one preferably elongated massage section with at least one wall that forms the outer surface of the massage section and having at least one electric drive device. The drive device has an electric motor unit, at least some sections of which are operatively connected either directly or indirectly to the wall in order to generate a massaging motion. A control assembly, which is connected to the electric motor unit, is provided to control the intensity of the massaging motion. The current electric power draw of the at least one electric motor unit is advantageously determined periodically or continuously, the electric power draw that has been determined is compared to at least one predefined reference power value and the intensity of the massaging motion is controlled depending on the result of said comparison.

Abstract: The invention relates to a massaging device in the shape of a rod having an essentially cylindrical end element, a shell forming the outer surface of the end element made of a rubber-elastic material and a drive unit for generating a motion on the end element, the drive unit forming a plurality of bearing and support surfaces, against which the shell bears and the bearing and support surfaces being designed for an oscillating deformation of the shell relative to the longitudinal axis (LA) of the end element radially outward and inward by means of radial stroke motions of the bearing and support surfaces. The massaging device features a first and second operating mode (T, W), in the first operating mode (T) the oscillating deformation along the longitudinal axis (LA) being in phase and in the second operating mode (W) out of phase.

Abstract: The invention relates to a massaging device with an elongated massaging recess for receiving a male genital organ, in which for massaging a male genital organ received in the elongated massaging recess a drive mechanism is provided extending along the longitudinal axis (LA) of the massaging recess. It is especially advantageous that the drive mechanism has a plurality of bearing surfaces, which are arranged at a radial distance from the longitudinal axis (LA) and which at least sectionwise surround the elongated massaging recess. A further advantage is that the drive mechanism is designed for an oscillating deformation of the elongated massaging recess at least radially inward along the longitudinal axis (LA) of the elongated massaging recess.
