Definitions

  • the invention relates to an acoustic element, which serves for sound insulation, and to a method for its production.
  • Corresponding acoustic elements are used, for example, as sound-absorbing, plate-shaped elements or panels in furniture fronts in kitchens or as doors.
  • a panel according to the present invention any more or less plate-shaped product, in particular made of wood, wood substitutes or other materials in which the sound insulation plays a role.
  • Corresponding panels with acoustic function or acoustic elements have hitherto been elaborately manufactured because a sound-absorbing material has to be integrated into a panel during the production process even during the production of the panel itself.
  • lightweight panels are used in their manufacture between a cover layer and the lightweight intermediate layer, a thin, sound-insulating material is introduced. This means that even before the panel is created, it must be determined that it must later have sound-absorbing properties.
  • the invention is therefore an object of the invention to provide an acoustic element and a method for producing such, in which this disadvantage does not occur.
  • acoustic element in a panel made of wood and / or wood substitute and / or plastic on a front side passages, in particular holes, holes or slots, introduced, wherein in the region of the passages, a sound-absorbing or sound-insulating material (3) is arranged.
  • a sound-absorbing or sound-insulating material (3) is arranged on the side facing away from the front side of the panel.
  • On the side facing away from the front side of the panel at least one opposite the rear of the panel recessed receiving area for receiving the sound-absorbing material is introduced.
  • the method according to the invention provides, in particular, for introducing at least one recess into the rear side of an already finished panel, for example by milling into which a sound-insulating material is introduced.
  • On the front passages in particular holes, holes or / and the like are introduced.
  • the back of the recess is closed by means of a cover or wall portion, which may also be a perforated and / or slotted plate, including the sound insulation material.
  • the provided with passages, for example, perforated and / or slotted plate or panel-shaped material absorbs the sound waves of the environment, which are broken in the internal absorber.
  • the back plate or lid with the passages in turn absorbs a portion of the sound waves passing through the absorber material.
  • the front and edge view of the acoustic element or the panel is fully preserved, so that can be manufactured with the invention optically approachless acoustic absorber.
  • the inventive method can be used in already finished panels, so that, for example, furniture fronts or doors can be retrofitted with a sound insulation.
  • acoustic element is shown (not limiting) as a deep-drawn panel, as used for example in fronts of kitchen furniture.
  • Panel can be any plate-shaped product, eg. B. also be a door, which has a front and a back.
  • the pages do not necessarily have to be flat. There may also be curved or other shaped surfaces.
  • the material may comprise a laminate, solid wood or other wood or wood substitute material as well as another material, which is suitable to be provided at least on the back with a recess.
  • the panel 1 has a front side 1a and a back side 1b.
  • passages 1d as holes, holes or slots are introduced.
  • a recess 4 is provided, which is introduced, for example by milling, such that the passages 1d in the front side 1d extend to the bottom 4b of the recess 4. If the passages 1d introduced after the introduction of the recess 4, this is done by drilling through the front side 1a to the bottom 4a of the recess 4.
  • a sound-absorbing material 3 is inserted into the recess 4. It can be provided depending on the requirements, a plurality of recesses 4, in each of which a sound insulating material 3 can be inserted.
  • a cover or wall section 2 is provided, which in turn is provided with passages 2a, e.g. in the form of slits or holes, interspersed.
  • the passages 2 a are preferably larger than the passages 1 d in the front side 1 a of the panel 1.
  • the lid or wall portion 2 is preferably formed slightly larger than the recess 4, so that it can rest on the back 1b.
  • the recess may have a recessed edge 4a opposite the rear side 1b, into which the cover or wall section 2 may preferably be inserted in a form-fitting manner. It can also be provided that the back 2b of the lid or wall portion 2 is flush with the back of the panel 1.
