  • the noises are dissipated as heat in air according to the absorption principle of a plate vibrator by the friction in at least one of the chamber walls 18, which is formed with another displaceable wall section, and by the friction of the vibrating chamber wall.
  • the chamber wall 18, which vibrates to absorb noise is also integrated into the chamber by a resilient spring device 17. Sound energy is also ultimately converted into heat and dissipated by the deformation of the spring and the resulting friction in the spring device 17.
  • the plate oscillator is a narrow-band resonance absorber, the mass and spring travel of which must be selected such that the characteristic absorber frequency for the highest possible degree of noise absorption as a function of the sound frequency is as close as possible or in the frequency range of the movement of the displaceable wall section 1.
  • the noise caused by the piston or membrane movement should be dissipated into heat in a porous structure according to the absorption principle.
  • the chamber walls 18 can be formed with a porous structure and, for example, in integrated into the plate oscillator or alternatively applied to the plate oscillator.
  • the noises are absorbed by means of the viscous flow losses of the air due to the friction on the porous damping material and the friction due to the deformation of the material.
  • the porous absorber is a broadband absorber, the layer thickness and material of which must be selected such that the characteristic absorber frequency for the highest possible degree of absorption is as close as possible or in the frequency range of the movement of the displaceable wall section 1.
  • the drive unit is formed with a few movable components of low weight and therefore has few unbalanced, free mass forces, which stimulate components or the housing of the stimulation device to oscillate or vibrate in certain displaceable wall sections.
  • the further displaceable wall section of the chamber wall 18 can optionally be designed with a ferrofluid 14 for damping the resonances of the voice coil 2 and a frame 13 or a closed chamber (not completely filled), which also ensures that the voice coil 2 and carrier 5 are cooled by the increased heat conduction compared to air.
  • the heat capacity of the deliberately lightweight voice coil 2 and carrier 5 are low.
  • the flexibility in the embodiment of the drive allows a great deal of freedom in the design of the stimulation device, making the drive elongated or wide and also the local pressure fluctuations that propagate at the speed of sound through noise absorption measures in the chamber (cf. Fig. 3 ) to reduce.
  • the drive unit or device has a comparatively low complexity due to the direct conversion of the electrical energy of the battery unit 28, for example from the accumulator, into a translational movement of a simple voice coil coupled to the displaceable wall section 1, which in the various versions - regardless of the specific drive -
  • a simple voice coil coupled to the displaceable wall section 1, which in the various versions - regardless of the specific drive -
  • the direct conversion also results in potentially high efficiency, compact design and low weight.
  • the movable wall section(s) 1 can be an integral part of the chamber (Pressure chamber - chamber in which the variable pressure field is generated), which ensures a good seal against compressible and incompressible media up to a certain excess and negative pressure of the chamber.
  • the displaceable wall section 1 can be used by means of more than one coil 2 and more than one carrier 5, as in Fig. 4 displayed, moved.

  • the displaceable wall section 1 there is at least one permanent magnet 7, for example in the form of a bar magnet as in Fig. 6 shown.
  • the permanent magnet 7 requires the highest possible flux density in order to induce the air gap 4, which must be kept as narrow as possible, between the permanent magnet 7 and the movable wall section 1 with the electrical conductors 2, which is why the strongest possible permanent magnets with flux densities of 0.5... 1.2T (for example neodymium -Iron-boron magnets) are used, which generate a strong magnetic field 3 with low weight.
  • the displaceable wall section 1 (for example made of a polymer or paper) as part of a first chamber of the stimulation device 9 can be integrated into the chamber via a bead 6, which mechanically follows the strokes of the displaceable wall section 1 largely without mechanical stresses.
  • the electrical conductors 2 on the movable wall section 1 are made of the most electrically conductive material possible (for example copper or silver) and are electrically insulated from one another by being integrated into the movable wall section 1.

  • the thin electrical conductors 2 are fed with an alternating control current from a control unit. Depending on the current direction or current polarity, the electrical conductors 2 are moved up or down in the magnetic field of the air gap 4 by the Lorentz force.
  • the driving forces act evenly over the entire surface of the displaceable wall section 1.
  • the directions of the Lorentz force, the magnetic field and the current flow are in Fig. 6 perpendicular to each other.
  • the electrical conductors via the two permanent magnets 7 must be fed with different polarities in order to cause the same movement.
  • the stroke of the deflection of the electrical conductors integrated into the displaceable wall section 1 is determined by the amplitude of the control current.
  • the frequency of the alternating current corresponds to the frequency of the conductor movement and thus the frequency of the movement of the displaceable wall section 1.
  • the frequency and the stroke of the displaceable wall section 1 can therefore be controlled comparatively easily by the current frequency and current amplitude independently of one another.
  • the changing pressure field and the resulting changing positive and negative pressure on the erogenous body zone (clitoris) can be controlled independently of one another in frequency and amplitude by the alternating compression and expansion of the air by means of the movement of the displaceable wall section 1.
  • alternating current Due to the direct transmission, an extended frequency range from less than 1Hz to several hundred Hz is easily possible with this principle.
  • the direct current from the accumulator simply needs to be converted into alternating current. Converting to alternating current can include switching on and off and/or superimposing direct current components. This allows an alternating voltage with a direct current offset to be provided. For example, an alternating voltage can be provided that does not include a change in polarity, but rather only a change in the voltage level while the voltage direction (polarity) remains the same.

  • the lamellar membrane there is at least one permanent magnet 7 (left), for example in the form of a bar magnet as in Fig. 13 shown.
  • the permanent magnet 7 requires the highest possible flux density in order to induce the air gap 4 between the permanent magnet 7 and the lamellar membrane with the electrical conductors 2, which must be kept as narrow as possible, which is why the strongest possible permanent magnets with flux densities of around 0.5 to around 1.2T (for example neodymium Iron-boron magnets) are used, which generate a strong magnetic field 3 with low weight.

  • the chamber of the stimulation device 10, the permanent magnet 7 and the side pole plates 19 are fastened in a frame 9 (for example made of plastic, aluminum or magnesium).
  • the lamellar membrane is as in Fig. 13 shown with parallel electrical conductor tracks 2 covered in a meandering shape.
  • the direction of current flow must be the same for all conductor tracks, since the magnetic field 3 also has the same orientation everywhere in the air gap 4, which must be kept as narrow as possible in terms of design.
  • the electrical conductors 2 are guided in a meandering shape on the lamellar membrane in such a way that the current flows through the adjacent lamellar in the opposite direction.
