Definitions

  • the invention relates to an acoustic absorber according to the preamble of claim 1 and to a use of such an acoustic absorber according to claim 13.
  • the problem underlying the invention is to enable as simple as possible and yet as efficient as possible sound absorption.
  • a carrier having a plurality of recesses such as
  • Foam or impermeable to air are formed.
  • the coating takes place in particular on a "visible side" of the carrier, ie a side of the carrier which is visible after assembly of the absorber, that is, for example, faces away from a mounting location (such as a wall) It is also conceivable that the coating is provided on a plurality of sides, in particular on mutually applied sides, of the carrier Sound waves which strike the absorber enter partially into the recesses of the carrier, sound energy being dissipated and the sound waves This effect is intensified by the covering of the openings with the lacquer coating, for example because the lacquer coating above the recesses has at least one opening which causes a narrowing of the recess and thus an increased (friction-induced) dissipation of the sound energy.
  • the variant of the invention according to which the sections of the coating covering the recesses are made impermeable to air, can be used in particular if the surface-related mass of the coating is small.
  • the air-impermeable design of the coating segments has the particular advantage that a substantially homogeneous, planar surface is obtained, which is e.g. can be easily cleaned.
  • the segments can each be formed at least substantially closed. This means, in particular, that the segments (or, for example, also the entire coating) do not have an open-pore lacquer material.
  • the recesses extend like a slit, i. they have a longitudinal extent that is larger (e.g., three times larger) than their width.
  • the openings in the lacquer layer are each approximately in the form of a slot extending transversely to the slots, the gaps being e.g. each a width of 0.1
  • This particular structure of the paint coating in the region of the recesses can be achieved in particular by the design of the edges of the recesses and / or the Dimensioning of the recesses are generated. For example, when the lacquer layer is produced (for example in the form of a powder coating or dip coating), the lacquer is drawn somewhat into the recesses due to capillary forces and tears transversely to the recesses, as a result of which the segments of the lacquer coating covering the recesses are separated from one another. It is also possible that prior to the application of the paint coating closure elements are introduced into the recesses, which serve to stabilize the paint coating in the region of the recesses. The closure elements can remain in the recesses after removal of the lacquer coating or can also be removed.
  • the recesses in the cross section are at least approximately circular, i. as holes.
  • the recesses go in particular through the entire carrier.
  • the recesses are arranged in a regular pattern and / or e.g. for displaying an image information, in particular for the pictorial representation of an object serve.
  • the recesses (in particular in the manner of a perforation) are arranged along a plurality of lines (contour lines) which represent the contours of an object.
  • the recesses do not have to have the same shape, size and / or geometry.
  • the distances between adjacent recesses vary.
  • each of the lacquer layers has recesses.
  • the recesses of the different lacquer layers are in particular arranged so that they at least partially overlap each other.
  • the carrier may be at least substantially planar.
  • the invention is of course not limited to a particular nature of the carrier. It is conceivable, e.g. Also, that the carrier is formed at least partially curved, folded or stepped.
  • the basic shape of the carrier (in plan view) also need not be rectangular. Rather, in principle, any basic shapes come into question (for example, round or jagged).
  • the carrier is, for example, a metal or plastic plate.
  • the invention also relates to the use of an acoustic absorber designed as described above as a surface cladding element, as a ceiling or wall element or as part of a furnishing object.
  • the invention relates to a piece of furniture with an acoustic absorber designed as described above.
  • the furniture is, for example, a shelf (such as a sales or presentation shelf).
  • a shelf such as a sales or presentation shelf.
  • floors of the shelf and / or at least one rear wall element are each formed by an acoustic absorber according to the invention. It is also possible that all floors and the rear wall are each formed by an absorber according to the invention.

  • FIG. 1 shows a plan view of a visible surface 21 of a carrier 2 of an acoustic absorber 1 according to the invention.
  • the carrier 2 has a plurality of recesses in the form of slots 22, which cause an increased energy dissipation of sound waves acting on the absorber 1.
  • the visible surface 21 of the carrier 2 is provided with a lacquer coating 3, which covers at least some of the slots 22 with portions 31.
  • the portions 31 of the lacquer coating 3 are somewhat drawn into the respective slot 22 due to the action of capillary forces.
  • the sections 31 each have a plurality of segments 31 1 through transverse to the longitudinal propagation of the slots 22 extending openings in the form of columns 312 are separated from each other.
  • the gaps 312 reduce the slits 22 in their upper area, thereby increasing the dissipation of sound wave energy.
  • the gaps 312 occur, in particular, during the production of the lacquer layer 3, the number of gaps depending on the width of the slots 22 and / or the nature of the edges of the slots. It should be noted that the gaps 312, as shown in FIG. 1, do not necessarily have to have a constant width. In the present case, the gaps 312 each widen outwardly from their center (in the middle of the slots 22) (toward side walls of the slots 22).
  • recesses instead of the slots 22 (at least instead of some of the slots 22), recesses of a different geometry, e.g. circular bores or star-shaped openings, can be used.

  • Fig. 2 shows the absorber 1 of Fig. 1 in cross section. It can be seen that the lacquer coating 3, as mentioned, in each case something is drawn into the slots 22 and correspondingly in the region of the slots 22 has indentations.
