  • the size and shape of these recesses depends on the size of the area in which haptic operating feedback is to take place. The minimum size of this recess is determined by the size of the input and output device 18, which is arranged on the back of the control panel 15. If a certain mechanical stabilization of the panel carrier 16 cannot be dispensed with at this point, the connection must be designed in such a way that the haptic effect or the structure-borne sound waves can still spread.
  • the transfer of the haptics to the control panel 15 is highly dependent on the mechanical and geometric structure of the control panel 12. This structure determines an adjustment or reduction of the power of the haptic actuator 19 and/or the signal duration of the haptic signal, depending on the desired strength of the haptic feedback.

  • Each previously mentioned embodiment of the control panel 12 experiences a maximum vibration excitation by the haptic actuator 19 in a certain frequency range. This is determined by the resonance frequency of the control panel 12 and depends on the two storage elements, mass and internal spring of the materials used.
  • the internal damping of the materials of the entire control panel 12 system determines the quality of the vibration system and thus the amplitude of the mechanical vibration and the width of the frequency range. In the range of the resonance frequency, the power can be greatly reduced depending on the quality of the resonance. The stronger the resonance vibration, the lower the power of the haptic actuator 19 can be selected, but the narrower the frequency range becomes.
  • the haptic function can be optimized with regard to manufacturing tolerances of all components and the best possible vibration generation.
  • the sound transmission decoupling from the surrounding device body 14 with regard to its cavity resonances and resonating materials must also be solved structurally. This can be achieved, for example, by the targeted attachment of heavy adsorber materials, which dampens disturbing structure-borne sound resonances.

To prevent this, the number of connections, for example screw connections, between the device body 14 and the control panel 12 can be reduced. Alternatively, the existing connections can be decoupled from structure-borne noise using elastic suspensions. Connecting materials with high internal damping can also reduce the disturbing structure-borne noise in this case.
  • the control panel 12 explained above has a number of advantages. On the one hand, it creates the possibility of equipping a rigid control panel 12 with a haptic element.
  • the performance of the haptic actuator 19 can be reduced by the three-layer design of the control panel 12 described above.
  • the haptic touch perception can be improved by the described design influencing of the control panel 12. This results in the possibility of selective haptics on a rigid control panel 12 with the help of several haptic actuators 19 with reduced performance.
