Definitions

  • the invention relates to a loudspeaker with a front attached sealing element, which with mounted speaker abuts a wall for acoustic sealing, and a method of manufacturing such a speaker.
  • the sealing of loudspeakers towards the door interior trim within motor vehicles is regularly done via open-cell, impregnated or non-impregnated foam sealing strips with Cross-sectional dimensions from 2 x 4 mm to 20 x 25 mm, like this 1 and 2 is shown schematically.
  • the foam sealing strip 12 is here on the speaker basket, one Speaker basket adapter, a speaker bracket or a Speaker grille glued on.
  • Fig. 1 is the foam sealing strip 12 ring-shaped and on the ring-shaped Glued on the outside of the speaker grille 10.
  • the cross section of the foam sealing strip is cuboid.
  • This foam sealing strip 12 lies with the speaker cover grille 10 facing away from the inside of the door panel 18 for acoustic sealing.
  • the Door trim 18 still has openings 19 so that the Speakers emitted acoustic waves in the interior of the vehicle.
  • the speaker itself is attached to the inner wall 16 of the door. Holes are used for this 11, 17 in the loudspeaker or in the door inner wall 16.
  • foam sealing strips have the disadvantage that they are first not an absolute seal due to its open cell structure and secondly, the liability of the foam sealing strips depends very much on the climatic conditions. So it turned out that in practice when used such seals from speakers to the door paneling Complaints from motor vehicles to motor vehicles about non-adherent, poorly adherent or partially or completely detached foam strips occur. It has been observed that such problems occur frequently when that Motor vehicle and thus the speaker with the glued on Foam sealing strips strong temperature fluctuations or was exposed to high humidity.
  • the diameter is particularly problematic relatively small speakers, from about 130 to 160 mm shown because there compared to the larger speakers the foam sealing strips have a narrower radius and consequently the release forces in the case of large temperature fluctuations and high humidity even bigger are.
  • Another problem with the glued-on foam sealing strips is the need for prefabrication or completion at the loudspeaker manufacturer.
  • An online production of the Loudspeaker on an automatic loudspeaker production line is not or only with such a sealing solution very high cost possible.
  • the object of the present invention is one Specify speakers with which an optimal acoustic seal is possible while being easy to manufacture as well as high temperature and humidity resistance. Furthermore, a method for producing such a Loudspeaker.
  • This task is accomplished through a speaker with the characteristics of claim 1 and by a manufacturing method with the feature of claim 12 solved.
  • the loudspeaker according to the invention essentially stands out through one piece to the front of the speaker molded sealing element made of a thermoelastic Polymer exists.
  • the sealing element on the speaker basket Speaker adapter to a bracket of the speaker or to the speaker grille or a similar part of the loudspeaker molded using two component technology become.
  • the cross section of the TPE sealing element designed so that the tolerance range, which is to be bridged, in the elastic deformation range of the TPE sealing element.
  • the cross section can, for example Be Z-shaped or approximately Z-shaped.
  • Fig. 3 is the cover grid in a perspective view 10 of a loudspeaker.
  • a sealing element made of thermoplastic elastomer (TPE) attached by injection molding.
  • 4 is an associated, partially sectional view shown. 4 is in the sectional view the complete loudspeaker in turn between the inner wall of the door, d. H. the inner door panel 16, and the door trim 18 built-in.
  • TPE thermoplastic elastomer
  • the TPE sealing element is on the speaker or the speaker grille 10 molded.
  • the speaker grille 10 is made of any plastic while the sealing element 13 according to the invention from a thermoplastic There is elastomer.
  • the thermoplastic elastomer can for example be a polypropylene material and in particular be a polycarbodiimide polymer.
  • As a material is in particular DAPLEN (registered trademark) and here the type DS65T20 is particularly suitable.
  • SEBS TPE based on polystyrene
  • Material with a SEBS molecular structure has molecules made from thermoplastic polystyrene end blocks (S) and an ethylene-butylene middle block (EB) consist. When the processed material cools down polystyrene domains are formed.
  • a usable one SEBS material is e.g. under the name PTS-thermoflex available in the stores.
  • the cross section of the TPE sealing element 13 is expedient chosen so that its route to the one to be sealed Wall, as to the inside of the door panel 18, still lies in the elastic deformation range.
  • the cross section of the TPE sealing element 13 approximately Z-shaped.
  • the distal end facing away from the speaker grille 10 of the TPE sealing element 13 lies sealingly on the inside the door trim 18.
  • the TPE sealing element 13 does not necessarily have to be on the Cover grille 13 of the speaker can be molded. It is also possible that the TPE sealing element on the speaker basket, a speaker adapter, a speaker holder or a similar element of the speaker is molded.
  • FIG. 5 is another embodiment of a loudspeaker shown according to the invention.
  • the perspective Representation lets you on a speaker base 56th mounted loudspeaker 50 with a loudspeaker membrane 52, a speaker surround 54 and a speaker basket adapter 62 recognize.
  • Speaker base 56, connector 60 and speaker basket adapter 62 can be used as a single combined part be executed.
  • the speaker base 56 is with holes or openings 58 and 59 provided for mounting the inner door wall, d. H. the inner door panel of a motor vehicle are provided.
  • On speaker base 56 is a connector 60 mounted to the speaker is electrically connected and via which the output of a Audio device can be coupled.
  • the speaker basket adapter 62 On the cylindrical speaker adapter 62 sits a TPE sealing element 64.
  • the speaker basket adapter 62 On the cylindrical speaker adapter 62 sits a TPE sealing element 64.
  • the speaker basket adapter 62 On its front end wall annular groove 62a in which a wall part of the TPE sealing element 64 is injected.
  • TPE sealing element 64 From the wall part lying orthogonal to the loudspeaker axis X. 62a of the TPE sealing element 64 extends to seen from the speaker axis X at an angle Wall part of the sealing element around in a sealing lip 66 to end. From this sealing lip 66 extends in a segment of a circle a third away from the speaker axis X. Wall part of the TPE sealing element 64. On this third The wall part of the TPE sealing element 64 is sealed to the door lining, in this case via a door cylinders molded directly onto the door trim.
