Description

TITRE : Agencement d’un ouvrant d’un véhicule comportant un dispositif acoustique. TITLE: Arrangement of an opening of a vehicle comprising an acoustic device.
Domaine technique de l'invention Technical field of the invention
L’invention concerne un agencement d’un ouvrant d’un véhicule, notamment un hayon, comportant un dispositif acoustique. L’invention concerne plus particulièrement un agencement d’un ouvrant d’un véhicule, notamment un hayon, comportant une structure de l’ouvrant, notamment réalisée par moulage d’une matière plastique, et au moins un dispositif acoustique comportant au moins un haut-parleur. The invention relates to an arrangement of an opening of a vehicle, in particular a tailgate, comprising an acoustic device. The invention relates more particularly to an arrangement of an opening of a vehicle, in particular a tailgate, comprising a structure of the opening, in particular produced by molding a plastic material, and at least one acoustic device comprising at least one high -speaker.
Etat de la technique antérieure State of the prior art
Un véhicule, en particulier un véhicule automobile, comprend généralement au moins un ouvrant et une caisse sur laquelle l’ouvrant est monté de manière articulée, notamment à rotation. Afin d’améliorer l’acoustique d’un système audio embarqué, il est bien souvent connu d’utiliser des volumes creux de la caisse ou d’ajouter de tels volumes pour créer dans ondes sonores à basses fréquences, conférant un effet de profondeur acoustique qui est appréciée par les utilisateurs. Un tel dispositif acoustique comprend pour ce faire un subwoofer, mais du fait du volume de son caisson, son intégration engendre parfois une réduction du volume de coffre. A titre d’exemple, il est connu d’ajouter au niveau du coffre, au niveau d’une garniture latérale de coffre ou au niveau du plancher de coffre, un subwoofer dont la taille du caisson pénalise le volume utile du coffre de chargement. A vehicle, in particular a motor vehicle, generally comprises at least one opening and a body on which the opening is mounted in an articulated manner, in particular in rotation. In order to improve the acoustics of an on-board audio system, it is often known to use hollow volumes of the body or to add such volumes to create low frequency sound waves, conferring an effect of acoustic depth which is appreciated by users. Such an acoustic device includes a subwoofer, but due to the volume of its box, its integration sometimes results in a reduction in trunk volume. For example, it is known to add at the level of the trunk, at the level of a side trunk trim or at the level of the trunk floor, a subwoofer whose size of the box penalizes the useful volume of the loading trunk.
Il est aussi connu d’utiliser le volume créé par le passage de roue arrière du véhicule pour implanter un tel dispositif acoustique, mais cela nécessite de longues heures d’études de faisabilité technique car la rigidité de la caisse est affaiblie pour loger le haut-parleur, ce qui requiert par la suite un travail de consolidation de la caisse. Aussi plaisante que cela puisse paraître, l’implantation d’un subwoofer directement à la caisse de véhicule reste une opération spécifique à chaque véhicule, car dépendant fortement de géométrie de caisse, de sorte qu’une telle conception de véhicule ne puisse pas être facilement transposable à des typologies différentes de caisse. It is also known to use the volume created by the rear wheel arch of the vehicle to install such an acoustic device, but this requires long hours of technical feasibility studies because the rigidity of the body is weakened to accommodate the loudspeaker. speaker, which subsequently requires work to consolidate the fund. As pleasant as it may seem, the installation of a subwoofer directly to the vehicle body remains an operation specific to each vehicle, because it strongly depends on body geometry, so that such a vehicle design does not cannot be easily transposed to different types of funds.
Une telle situation n’est pas acceptable. Such a situation is not acceptable.

Description détaillée detailed description
La direction selon laquelle un véhicule, notamment un véhicule automobile, se déplace en ligne droite est définie comme étant la direction longitudinale X. Par convention, la direction perpendiculaire à la direction longitudinale, située dans un plan parallèle au sol, est nommée direction transversale Y. La troisième direction, perpendiculaire aux deux autres, est nommée direction verticale Z. Ainsi, on utilise un repère direct XYZ dans lequel X est la direction longitudinale dans le sens avant-arrière du véhicule, donc dirigée vers l’arrière, Y est la direction transversale dirigée vers la droite et Z est la direction verticale dirigée vers le haut. Le sens avant correspond au sens dans lequel le véhicule se déplace habituellement dans la direction longitudinale et est opposé au sens arrière. The direction in which a vehicle, in particular a motor vehicle, travels in a straight line is defined as the direction longitudinal direction XYZ in which The forward direction is the direction in which the vehicle usually travels in the longitudinal direction and is opposite to the reverse direction.
La figure 1 illustre schématiquement un ouvrant 1 , qui est ici du type d’un hayon de fermeture d’un compartiment arrière d’un véhicule, notamment d’un compartiment à bagages d’un véhicule automobile. Figure 1 schematically illustrates an opening 1, which here is of the type of a tailgate closing a rear compartment of a vehicle, in particular a luggage compartment of a motor vehicle.
L’ouvrant comprend une structure 2 qui est réalisée par un procédé de moulage d’une matière plastique. L’agencement de l’invention tire profit de cette typologie de conception pour intégrer de nouvelles fonctions améliorant le process de fabrication et la qualité d’assemblage. The opening comprises a structure 2 which is produced by a process of molding a plastic material. The layout of the invention takes advantage of this design typology to integrate new functions improving the manufacturing process and assembly quality.
En tant que pièce plastique, la face intérieure de la structure peut faire office d’élément d’aspect sans requérir d’ajout particulier d’une quelconque pièce de garniture. L’agencement objet de l’invention tire parti de cet avantage en intégrant un dispositif acoustique directement à la structure 2 de l’ouvrant. Le dispositif acoustique est ici visible sur la face intérieure de l’ouvrant, c’est-à-dire sur la face de l’ouvrant destinée à délimiter le volume du compartiment arrière, lequel peut notamment être du type d’un coffre. La face extérieure de la structure 2 est quant à elle destinée à être recouverte d’un panneau 4 extérieur pouvant être réalisé à partir d’une tôle d’acier, qui est rendue visible de l’extérieur du véhicule. Un espace intérieur 5 de l’ouvrant 1 est alors délimité par la superposition de la structure 2 et du panneau 4 extérieur. La profondeur de l’espace intérieur 5 de l’ouvrant définit la profondeur de l’ouvrant qui intègre le dispositif acoustique 3. Sur la figure 2, il est représenté l’ouvrant 1 comprenant un dispositif acoustique 3, principalement constitué de deux éléments actifs identifiables par les haut-parleurs 33. As a plastic part, the interior face of the structure can act as an appearance element without requiring the particular addition of any piece of trim. The arrangement which is the subject of the invention takes advantage of this advantage by integrating an acoustic device directly into structure 2 of the opening. The acoustic device is visible here on the interior face of the opening, that is to say on the face of the opening intended to delimit the volume of the rear compartment, which can in particular be of the type of a trunk. The exterior face of the structure 2 is intended to be covered with an exterior panel 4 which can be made from a steel sheet, which is made visible from outside the vehicle. An interior space 5 of the opening 1 is then delimited by the superposition of the structure 2 and the exterior panel 4. The depth of the interior space 5 of the opening defines the depth of the opening which integrates the acoustic device 3. In Figure 2, the opening 1 is shown comprising an acoustic device 3, mainly made up of two active elements identifiable by the speakers 33.
L’élément de structure 2 comprend au moins une zone d’accueil destinées à recevoir un dispositif acoustique 3, la zone d’accueil formant pour partie un élément statique du dispositif acoustique 3. The structural element 2 comprises at least one reception zone intended to receive an acoustic device 3, the reception zone partly forming a static element of the acoustic device 3.
Selon le mode de réalisation préféré tel qu’illustré sur les figures, l’ouvrant 1 comprend deux zones d’accueil qui sont des logements 21 disposés symétriquement par rapport au plan médian transversal XZ de l’ouvrant 1 . Chaque logement 21 est destiné à loger en tout ou partie un élément actif du dispositif acoustique 3. Chaque logement 21 se présente sous la forme d’une boite de réception qui apporte en outre une amélioration locale de la rigidité de l’ouvrant. Chaque logement 21 peut être assimilé à une poutre de rig idification qui s’étend au travers de l’ouvrant 1 , c’est-à-dire dans la profondeur de l’ouvrant, en ce sens qu’il comprend au moins une paroi transversale se prolongeant le long de l’axe X. Selon un mode de réalisation préféré, le logement 21 comprend une unique paroi délimitant un volume de révolution d’axe X et qui s’étend en profondeur dans la structure de l’ouvrant. Chaque logement 21 comprend des parois latérales droite et gauche ainsi que des parois supérieure et inférieure toutes reliées entre elles par des portions courbées de sorte à former une continuité de ligne propre au concept d’unique paroi transversale. La rigidité de la structure 2 est en outre donnée par la présence d’une paroi de fermeture de la poutre qui relie vient à recouvrement du bord arrière de la paroi transversale. According to the preferred embodiment as illustrated in the figures, the opening 1 comprises two reception zones which are housings 21 arranged symmetrically with respect to the transverse median plane XZ of the opening 1. Each housing 21 is intended to house in whole or in part an active element of the acoustic device 3. Each housing 21 is in the form of a reception box which also provides a local improvement in the rigidity of the opening. Each housing 21 can be compared to a rigidification beam which extends through the opening 1, that is to say in the depth of the opening, in the sense that it comprises at least one wall transversal extending along the axis X. According to a preferred embodiment, the housing 21 comprises a single wall delimiting a volume of revolution of axis Each housing 21 comprises right and left side walls as well as upper and lower walls all connected together by curved portions so as to form a continuity of line specific to the concept of a single transverse wall. The rigidity of structure 2 is also given by the presence of a closing wall of the beam which connects to overlap the rear edge of the transverse wall.
La poutre de rigidification délimite le logement 21 à l’intérieur duquel l’élément actif du dispositif acoustique 3 est apte à être disposé. L’élément actif est ici un haut-parleur 31 . The stiffening beam delimits the housing 21 inside which the active element of the acoustic device 3 is able to be placed. The active element here is a loudspeaker 31.
Le dispositif acoustique 3 comprend en outre un élément passif qui est pour partie formé par les parois délimitant le logement, et qui vise à créer un caisson 32 de basses. Le caisson 32 de basses est ainsi délimité par des parois de fixation 34, de fond 35 et de liaison 36 reliant entre elles les parois de fixation 34 et de fond 35. The acoustic device 3 further comprises a passive element which is partly formed by the walls delimiting the housing, and which aims to create a subwoofer 32. The subwoofer 32 is thus delimited by fixing walls 34, bottom 35 and connecting walls 36 interconnecting the fixing walls 34 and bottom 35.
La paroi de liaison 36 du caisson 32 de basses est la paroi transversale de la poutre de rigidification susmentionnée. Les parois de liaison 36 sont non parallèles mais légèrement inclinées l’une par rapport à l’autre, ce qui limite le phénomène d’ondes stationnaires à l’intérieur du caisson. Il en résulte une nette réduction des risques de distorsion du son. The connecting wall 36 of the subwoofer 32 is the transverse wall of the aforementioned stiffening beam. The connecting walls 36 are not parallel but slightly inclined relative to each other, which limits the phenomenon of standing waves inside the box. This results in a clear reduction in the risk of sound distortion.
La paroi de fond 35 du caisson 32 est la paroi de fermeture de la poutre de rigidification susmentionnée. La paroi de fond peut comprendre un trou traversant pour le passage d’un fil d’alimentation en relation avec l’élément actif du dispositif acoustique 3. The bottom wall 35 of the box 32 is the closing wall of the aforementioned stiffening beam. The bottom wall may include a through hole for the passage of a power wire in relation to the active element of the acoustic device 3.
Le logement 21 est la poutre de rigidification qui contribue à la tenue mécanique de la structure plastique du hayon, notamment en réduisant son régime vibratoire. La paroi périphérie de la poutre de rigidification donne la rigidité qui évite une déformation des faces planes de la structure de l’ouvrant sous un certain régime vibratoire. Housing 21 is the stiffening beam which contributes to the mechanical strength of the plastic structure of the tailgate, in particular by reducing its vibration regime. The periphery wall of the stiffening beam provides rigidity which prevents deformation of the flat faces of the opening structure under a certain vibration regime.
L’ouvrant 1 comprend de part et d’autre d’un plan médian d’axe XZ des logements 21 qui sont sensiblement identiques, à la symétrie près. The opening 1 comprises on either side of a median plane of axis XZ housings 21 which are substantially identical, except for symmetry.
Comme cela est rendu visible sur la figure 1 , les logements 21 s’inscrivent à l’intérieur d’un anneau 6 de rigidification qui peut être formé par un élément tubulaire cintré qui est rapporté sur la structure 2, ou qui peut être directement formé dans la matière de la structure de l’ouvrant, notamment par moulage. L’anneau 6 de rigidification peut être en tout ou partie une veine creuse 10 qui est réalisée par l’injection d’un fluide sous pression.As is made visible in Figure 1, the housings 21 fit inside a stiffening ring 6 which can be formed by a curved tubular element which is attached to the structure 2, or which can be directly formed in the material of the structure of the opening, in particular by molding. The stiffening ring 6 can be in whole or in part a hollow vein 10 which is produced by the injection of a fluid under pressure.
L’anneau de rigidification 6 contourne une ouverture 7 de la structure 2 d’ouvrant. Une partie supérieure de la structure 2 comprend un encadrement de vitre délimitant l’ouverture 7. Un ouvrant de type d’un hayon arrière de coffre peut comprendre des moyens d’articulation (non représentés) en partie sommitale de la partie supérieure de la structure 2 qui permettent le basculement de l’ouvrant autour de la caisse du véhicule. Une partie inférieure de la structure 2 comprend un support destiné au montage d’éléments fonctionnels, par exemple une serrure. The stiffening ring 6 bypasses an opening 7 of the opening structure 2. An upper part of the structure 2 comprises a window frame delimiting the opening 7. An opening of the type of a rear trunk hatch may comprise articulation means (not shown) in the top part of the upper part of the structure 2 which allow the opening to tilt around the body of the vehicle. A lower part of the structure 2 comprises a support intended for mounting functional elements, for example a lock.
L’agencement de l’ouvrant se caractérise par un positionnement du caisson 32 de basses au niveau de la partie inférieure de la structure 2, notamment parce que la profondeur de l’ouvrant propose un dimensionnement du caisson de basses en adéquation avec l’effet sonore recherché. The arrangement of the opening is characterized by a positioning of the subwoofer 32 at the level of the lower part of the structure 2, in particular because the depth of the opening proposes a dimensioning of the subwoofer in line with the desired sound effect.
De manière préférentielle, chaque logement 21 est situé à proximité d’un coin inférieur droit ou gauche de la poutre 6 de rigidification. La poutre 6 de rigidification en combinaison des logements 21 vise à améliorer la tenue à la déformation de la structure de l’ouvrant ainsi qu’à réduire le régime vibratoire qui est source de nuisance sonore. Preferably, each housing 21 is located near a lower right or left corner of the stiffening beam 6. The stiffening beam 6 in combination with the housings 21 aims to improve the resistance to deformation of the structure of the opening as well as to reduce the vibration regime which is a source of noise pollution.
L’élément statique du dispositif acoustique comprend une tuyère 33 qui est visible sur la figure 3 et qui va à présent être détaillée ci-après. The static element of the acoustic device comprises a nozzle 33 which is visible in Figure 3 and which will now be detailed below.
La tuyère 33 est un conduit évent qui améliore l’effet acoustique procuré par le caisson 32 de basses, en ce sens qu’il permet une circulation d’air améliorée du dispositif acoustique, ce qui tend à améliorer par la même le rendu sonore. La tuyère 33 se présente sous la forme d’un conduit reliant l’intérieur du logement 21 à l’extérieur de la structure 2. Dans ce but, la paroi de liaison 36 et la paroi de fixation 34 comprennent respectivement un trou d’évent 332 et 331 . Le flux d’air est optimisé par une charge Bass- reflex® dotée de ce conduit d’évent. The nozzle 33 is a vent duct which improves the acoustic effect provided by the subwoofer 32, in the sense that it allows improved air circulation of the acoustic device, which tends to improve the sound reproduction. The nozzle 33 is in the form of a conduit connecting the interior of the housing 21 to the exterior of the structure 2. For this purpose, the connecting wall 36 and the fixing wall 34 respectively comprise a vent hole 332 and 331. Airflow is optimized by a Bass-reflex® charge equipped with this vent duct.
Le logement 21 est en outre un logement tronconique présentant une paroi de fond inclinée par rapport à la base définie par la paroi de fixation 34.The housing 21 is also a frustoconical housing having a bottom wall inclined relative to the base defined by the fixing wall 34.
La paroi de liaison 36 est de dimension évolutive de sorte qu’une zone intérieure de la paroi 36 confère au logement 21 une profondeur moindre à celle d’une zone opposée délimitant la partie extérieure du caisson de basses. The connecting wall 36 has a scalable dimension so that an interior zone of the wall 36 gives the housing 21 a lesser depth than that of an opposite zone delimiting the exterior part of the subwoofer.
L’un des trous d’évent peut être disposé au niveau de la zone intérieure de la paroi de liaison 36. One of the vent holes can be arranged at the interior area of the connecting wall 36.
A noter que sur la figure 3 est représenté en détail la conformation de la tuyère 33 reliant l’intérieur du caisson de basses à l’extérieur de l’ouvrant. L’un des trous d’évent 331 , 332 est situé à proximité de la paroi de fond 35, au niveau de la paroi de liaison 36. L’autre des trous d’évent 331 , 332 est situé à proximité d’une zone périphérique du logement 21 qui contient le moyen de fixation du haut-parleur. La tuyère peut être de section évolutive de telle sorte que la section du trou d’évent 331 de la paroi de fixation est section supérieure à celle du trou d’évent de la paroi de liaison. Par section évolutive, il faut entendre que la tuyère présente un profil approximativement conique ouvert sur l’extérieur. Note that in Figure 3 is shown in detail the configuration of the nozzle 33 connecting the interior of the subwoofer to the exterior of the opening. One of the vent holes 331, 332 is located near the bottom wall 35, at the connecting wall 36. The other of the vent holes 331, 332 is located near a zone peripheral of housing 21 which contains the means of fixing the loudspeaker. The nozzle can be of scalable section such that the section of the vent hole 331 of the fixing wall is section greater than that of the vent hole of the connecting wall. By evolving section, it is meant that the nozzle has an approximately conical profile open to the outside.
La tuyère 33 relie ainsi deux portions adjacentes de la structure 2 qui évoluent de manière sensiblement perpendiculaire l’une à l’autre, ce qui tend à améliorer localement la rigidité du logement 21. Ces portions adjacentes sont la paroi de liaison 36 et la paroi de fixation 34, cette dernière étant une partie confondue de la partie de la structure qui reste visible, en ce sens qu’elle n’est pas destinée à être recouverte par un quelconque élément de garniture. The nozzle 33 thus connects two adjacent portions of the structure 2 which evolve in a manner substantially perpendicular to each other, which tends to locally improve the rigidity of the housing 21. These adjacent portions are the connecting wall 36 and the wall fixing 34, the latter being a combined part of the part of the structure which remains visible, in the sense that it is not intended to be covered by any trim element.
Le moyen de fixation, qui permet le montage réversible du haut-parleur à la structure de hayon, peut être constitué de plusieurs bagues de fluage réalisées en acier, qui ont été insérées dans la moule avant injection de la matière plastique utilisée à la fabrication de la structure 2 d’ouvrant. Préférentiellement les bagues de fluages sont réparties uniformément autour du logement 21 de sorte qu’elles sont aptes à venir directement en prise avec une couronne du haut-parleur qui comprend des pattes de fixation, notamment trois pattes de fixation espacées d’un angle d’environ 120° l’une de l’autre. The fixing means, which allows the reversible mounting of the speaker to the tailgate structure, can consist of several creep rings made of steel, which were inserted into the mold before injection of the plastic material used in the manufacture of the opening structure 2. Preferably the creep rings are distributed uniformly around the housing 21 so that they are able to come directly into engagement with a crown of the loudspeaker which comprises fixing lugs, in particular three fixing lugs spaced at an angle of approximately 120° from each other.
Sur la figure 2, le trou d’évent 331 qui est situé à équidistance de deux bagues de fluage. In Figure 2, the vent hole 331 which is located equidistant from two creep rings.
La tuyère 33 débouche au niveau de la paroi de fixation 34 par un trou d’évent 331 qui est disposé à proximité d’une veine creuse 10, formant une poutre de rigidification, qui présente un profil sensiblement en U au niveau d’une partie inférieure de l’ouvrant 1 , de telle manière que la veine creuse 10 de la structure 2 et la tuyère 33 s’étendent dans des plans sensiblement orthogonaux entre eux. La tuyère 33 est principalement inscrite dans un plan XY tandis que la poutre 10 de rigidification tend à évoluer majoritairement dans un plan ZY. The nozzle 33 opens at the level of the fixing wall 34 through a vent hole 331 which is arranged near a hollow vein 10, forming a stiffening beam, which has a substantially U-shaped profile at the level of a part lower part of the opening 1, in such a way that the hollow vein 10 of the structure 2 and the nozzle 33 extend in planes substantially orthogonal to each other. The nozzle 33 is mainly in an XY plane while the stiffening beam 10 tends to evolve mainly in a ZY plane.
La structure 2 d’ouvrant 1 selon l’agencement décrit précédemment présente ainsi une rigidité améliorée par la présence d’un ensemble de poutre de rigidification constitué des logements 21 , des tuyères 33 et de la veine creuse 10. The structure 2 of opening 1 according to the arrangement described above thus presents improved rigidity by the presence of a set of stiffening beams consisting of housings 21, nozzles 33 and hollow vein 10.
Le procédé de fabrication de l’agencement de l’ouvrant 1 décrit précédemment, peut comprendre les étapes suivantes : The manufacturing process for the arrangement of the opening 1 described above may include the following steps:
- positionner un dispositif de fixation d’un dispositif acoustique, notamment des bagues anti-fluage, à l’intérieur d’un moule destiné à la fabrication d’une structure 2 d’ouvrant 1 , - position a device for fixing an acoustic device, in particular anti-creep rings, inside a mold intended for the manufacture of a structure 2 of an opening 1,
- fabriquer la structure 2 par moulage d’une matière plastique, - manufacture structure 2 by molding a plastic material,
- injecter un fluide sous pression, notamment un gaz, à l’intérieur du moule de matière plastique à l’état déformable afin de créer une tuyère, - inject a fluid under pressure, in particular a gas, inside the plastic mold in a deformable state in order to create a nozzle,
- assembler l’élément actif 31 du dispositif acoustique 3 à la structure 2 d’ouvrant 1 par l’intermédiaire du dispositif de fixation, notamment par vissage au travers des bagues anti-fluage. - assemble the active element 31 of the acoustic device 3 to the structure 2 of opening 1 via the fixing device, in particular by screwing through the anti-creep rings.
Le procédé de fabrication de l’ouvrant peut aussi comprendre l’injection d’un fluide sous pression pour créer un corps creux formant une poutre de rigidification 10 s’étendant approximativement à la périphérie d’une partie inférieure de la structure 2. The method of manufacturing the opening can also include the injection of a fluid under pressure to create a hollow body forming a stiffening beam 10 extending approximately to the periphery of a lower part of the structure 2.
Préférentiellement, les étapes d’injection du fluide sous pression pour la création de la poutre 10 de rigidification et la tuyère 33 sont réalisées en concomitance. Preferably, the steps of injecting the fluid under pressure for the creation of the stiffening beam 10 and the nozzle 33 are carried out concomitantly.
Préférentiellement, le fluide sous pression à injecter pour la création des corps creux est un gaz, notamment de l’air, mis sous pression par un fluide de refroidissement, notamment de l’eau. Preferably, the pressurized fluid to be injected for the creation of the hollow bodies is a gas, in particular air, pressurized by a cooling fluid, in particular water.
Grâce à la solution, l’intégration du dispositif acoustique dans l’ouvrant est facilitée par le procédé de fabrication de l’ouvrant dont la structure est en matière plastique. L’agencement d’un ouvrant comprenant un caisson de basses directement réalisé dans la matière utilisée à la fabrication de la structure de caisse permet également d’atteindre un haut niveau de rigidité. En outre, la création de corps creux utiles à l’intégration d’un dispositif acoustique tend à améliorer la tenue mécanique et vibratoire de l’ouvrant. En remarque, la solution présente l’avantage de pouvoir être facilement utilisée sur d’autres types d’ouvrants réalisés en matière plastique, quel que soit les critères esthétiques exigeants. Elle présente aussi l’avantage de ne pas impacter l’espace de chargement du véhicule. Thanks to the solution, the integration of the acoustic device into the opening is facilitated by the manufacturing process of the opening whose structure is made of plastic material. The arrangement of an opening including a subwoofer made directly from the material used in the manufacture of the body structure also makes it possible to achieve a high level of rigidity. In addition, the creation of hollow bodies useful for the integration of an acoustic device tends to improve the mechanical and vibrational strength of the opening. As a side note, the solution has the advantage of being able to be easily used on other types of openings made of plastic, whatever the demanding aesthetic criteria. It also has the advantage of not impacting the vehicle's loading space.
