MOUNTING ARRANGEMENT OF A LOUDSPEAKER IN A MOTOR VEHICLE

Description

[0001] The invention relates to a mounting arrangement of a loudspeaker in a motor vehicle, for example in a vehicle door. In particular, the invention relates to a preferably bayonet-type mounting arrangement of a loudspeaker on a support element of the motor vehicle.

[0002] From DE 101 44 665 B4, a vehicle door with an inner door panel as a wall is known, to which a loudspeaker is attached. The wall has a receiving opening into which the loudspeaker is inserted and fastened to the wall by means of screws, rivets, or the like. In a lower section of the loudspeaker, specifically within its loudspeaker basket and below a mounting axis there, a water drain is provided into a wet area, which is separated from a dry area of ​​the vehicle door by the wall.

[0003] From DE 20 2005 014 605 U1, a vehicle door is known with a wall facing the interior of the vehicle and having a receiving opening for a loudspeaker. Integral fastening means are provided in the area of ​​the receiving opening or on the loudspeaker, which together with receiving means form a plug connection designed as a snap-fit ​​or clip connection, a bayonet fitting, or a threaded connection.

[0004] From DE 20 2005 014 602 U1, a vehicle door with an inner wall and a loudspeaker arranged in a receiving opening in the wall, having an integrally molded sealing surface, is known. The loudspeaker can be brought into contact with the wall using a sealant integrally molded to the wall. The loudspeaker can be attached to the wall by means of a bayonet fitting, whereby the loudspeaker, inserted into the receiving opening, is locked in place by a rotational movement with corresponding receiving elements.

[0005] The invention is based on the objective of providing a particularly suitable mounting arrangement or mounting device for a loudspeaker of a motor vehicle, especially in a vehicle door. In particular, the loudspeaker should be mountable as easily as possible, preferably also avoiding mounting errors (poke yoke), and securely attached to a support element (base support), especially as a wall for the loudspeaker or its loudspeaker basket, or more generally, its loudspeaker housing, preferably without the need for additional fastening means such as mounting screws, rivets, a mounting ring, or the like. Furthermore, a particularly suitable door module with such a mounting arrangement is to be specified.

[0006] With regard to the assembly arrangement, the aforementioned problem is solved according to the invention with the features of claim 1 and with regard to the door module with the features of claim 13. Advantageous embodiments and further developments are the subject of the dependent claims.

[0007] The mounting arrangement or device for a loudspeaker in a motor vehicle, particularly in a vehicle door, comprises a support element with a receiving opening for the loudspeaker surrounded by an opening edge. The support element preferably serves as a base support and is expediently a component or integral part of a carrier plate (door module carrier plate) installed in a vehicle door, or of a plate-like door module carrier, for example, made of plastic, which serves to separate a wet area from a dry area of ​​the vehicle door, or is a component connectable to an inner door panel. The support element can also serve as a baffle for the loudspeaker, and the receiving opening can also be a baffle opening.

[0008] The term "mounting arrangement or device" also includes a fastening structure for mounting a loudspeaker on a base carrier or door module carrier (aggregate or component carrier) of a motor vehicle door, in particular a door module or for such a module.

[0009] The term "loudspeaker" as used here and in the following refers to a sound transducer, particularly one based on the cloth coil principle (moving-coil loudspeaker), comprising a diaphragm, a drive unit, and connecting elements. Specifically, the loudspeaker includes a speaker basket, a diaphragm (loudspeaker diaphragm), a surround (rubber surround), a spider, a voice coil, and a permanent magnet. The diaphragm is typically connected to a flange via the surround and, via the spider, to, for example, tapered, wall or basket struts in the area of ​​the speaker basket's base. The diaphragm is driven by the centrally mounted voice coil, which vibrates in the magnetic field of the permanent magnet located at the base of the basket, thus setting the diaphragm in motion and guiding it with the spider.In particular, the loudspeaker is a low-mid or midrange loudspeaker with a basket flange diameter of, for example, 12cm to 15cm and with a frequency response of, in particular, 40Hz or 200Hz to 2kHz.

[0010] The receiving opening on the support side is, for example, cup-shaped or conical, in particular with a recessed or deep-drawn wall. Here and in the following, "receiving opening on the support side" means that the receiving opening is an integral part of the support element.

[0011] The mounting arrangement or device further comprises a loudspeaker basket with a flange and with wall or basket struts between the flange and a basket base. The basket struts form a basket wall that is preferably interrupted in the circumferential direction of the loudspeaker basket, i.e., not completely closed or not entirely closed on the circumference. With respect to a preferably annular flange and a circular receiving opening on the support side, as well as an axis perpendicular to this, the basket struts can extend from the flange to the basket base at an angle of inclination, whereby the basket base can be axially offset from the rear of the flange, which serves as the mechanical mounting or connection interface (flange back).

[0012] Preferably, the loudspeaker basket is shaped approximately like a pot, with its flange forming an axially extending flange wall that is expediently at least partially closed around its circumference. Between this flange wall and the basket base, or within it, a perforated-web structure is provided with circumferentially extending, expediently arcuate or elongated, through-openings, between which the basket or wall struts are formed.

[0013] The mounting arrangement or device also includes a sealing element. This element serves to seal the loudspeaker, or its speaker basket, against the support element. The sealing element is located in the area of ​​a connection or interface between the loudspeaker basket, particularly its flange, and the edge of the mounting opening. Advantageously, the sealing element is bonded to the loudspeaker basket and its flange by means of a material bond. The sealing element appropriately surrounds the connection interface completely.

[0014] During the mounting of the loudspeaker to the support element, the bottom of the loudspeaker basket extends through the receiving opening on the support element in such a way that the flange on the basket rests against the edge of the receiving opening with the sealing element in place. In other words, the mounting arrangement is designed such that, during the mounting of the loudspeaker to the support element, the flange on the basket, with its rear flange facing the bottom of the loudspeaker basket, rests against the edge of the recess on the support element with the sealing element in place. Here and in the following, "basket-side flange" means that the flange is an integral part of the loudspeaker basket.

[0015] In the case of a support element that separates a dry space facing the vehicle interior from a wet space (towards the outer door skin) in a vehicle door, the basket base and the wall or basket struts of the loudspeaker basket are located in the wet space, while the flange of the loudspeaker is located in the dry space and the diaphragm of the loudspeaker faces the vehicle interior from the front.

[0016] The loudspeaker basket features a number of joining elements, particularly those arranged on the wall struts. These correspond to joining contours on the support surface, specifically to tabs (radial tabs), webs, or ribs projecting into the receiving opening, radially inward, or radially oriented, creating a bayonet-style connection as a combined plug-and-twist joint. This mounting arrangement thus enables a particularly simple and reliable connection of the loudspeaker or its basket to the support surface without additional fasteners such as screws, rivets, snap-in or clip elements, or a retaining ring. Here and in the following, "support surface joining contour" refers to the joining contour being an integral part of the support surface.

[0017] The term "bayonet fitting" here and in the following refers to a connection between the loudspeaker, its basket, or its housing and the mounting element through a combined insertion and rotational movement. This involves, first, a movement along a (rotational) axis normal to the interface plane during the insertion process, followed by a rotational movement around this axis, similar to a twist lock. The interface plane is the plane of the mounting interface between the mounting opening on the carrier side and the flange on the basket side.

[0018] According to a further development of the joining connection between the loudspeaker or its loudspeaker basket and the support element at the interface of the bayonet fitting, the basket-side joining element has claw-like hook or locking structures as integral fastening means of the loudspeaker basket. During the manufacture of the bayonet fitting, these structures engage the corresponding, support-side joining contours as integral fastening means of the support element in the area of ​​the interface. In other words, the respective support-side joining contour, which is preferably formed as a radial tab on the opening edge of the support-side recess, engages behind or under the associated basket-side joining element during the rotation of the loudspeaker basket relative to the support element. This joining element is advantageously a locking hook that is formed on the loudspeaker basket and preferably on the corresponding basket or wall strut.The term "basket-side joining element" is understood here and in the following to mean that the joining element is a component of the loudspeaker basket.

[0019] In In an advantageous embodiment, a snap-fit ​​connection is formed between at least one of the basket-side joining elements and the corresponding support-side joining contour when the bayonet fitting between the loudspeaker basket and the support element is or is being manufactured. Suitablely, at least one of the basket-side joining elements has a snap-fit ​​contour, and the support-side joining contour has a corresponding snap-fit ​​element which, during the manufacture of the bayonet fitting between the loudspeaker basket and the support element, engages in the basket-side snap-fit ​​contour, particularly preferably via an entry ramp leading into the basket-side snap-fit ​​contour.

[0020] According to a particularly advantageous embodiment, arc-shaped cutouts and / or at least one axial lug are provided on the basket-side flange between the carrier-side joining contours. The carrier-side cutouts are designed to accommodate the basket-side joining elements during the insertion movement when forming the bayonet fitting between the loudspeaker basket and the carrier element. The carrier-side cutouts provide different arc lengths, for example, through additional radial struts within the cutouts, so that during the insertion movement, there is only one possible insertion position of the loudspeaker basket into the carrier-side recess for forming the bayonet fitting. Additionally or alternatively, the basket-side axial lugs can prevent incorrect or unintended insertion of the loudspeaker or its basket.This reliably prevents assembly errors, especially when using the Poka-Yoke principle for direct error detection.

[0021] In a preferred embodiment, the sealing element is designed as a two-component seal or two-component sealing ring (two-component seal or sealing ring) with a soft sealing component and a comparatively hard or rigid sealing component. The sealing element suitably has two concentric sealing lips, one of which, in particular a radially outer sealing lip, projects axially beyond the other sealing lip. The radially inner of these sealing lips, which is advantageously designed as a comparatively hard or rigid sealing component, preferentially serves as a radial sealing element (radial seal) and, in particular, as a centering element during the (plug-in) assembly of the loudspeaker or its basket into the receiving opening of the support element in the area of ​​the connection or interface. The radially inner sealing lip thus preferably performs a dual function.The radially outer, axially projecting sealing lip, which is expediently designed as a comparatively soft sealing component, serves in particular as an axial sealing element (axial seal) for reliably sealing the loudspeaker against the support element.

[0022] Another aspect of the mounting arrangement or device provides that a ramp (launch ramp) extending circumferentially around the flange of the loudspeaker basket, particularly in the shape of a circular arc, is provided on the flange side facing the opening edge of the receiving opening (rear flange side). This ramp suitably extends only over a limited circular arc or segment, particularly with a central angle of the radii of the circular arc between 10° and 30°, preferably between 15° and 20°.

[0023] Suitablely, several, preferably three, ramps are provided on the basket-side flange. Each ramp serves to generate a contact force on the sealing element, particularly during the rotational movement when forming the bayonet fitting between the loudspeaker or its basket and the support element. The ramp is suitably positioned upstream of an associated basket-side joining element such that, during the bayonet fitting process of the loudspeaker or its basket, the support-side joining contour or radial lug is located within the same radius range as the basket-side ramp. The ramp is particularly advantageously positioned in the area of ​​the interface between the support-side receiving opening and the sealing element.In other words, the ramp is advantageously located radially inwards of the sealing element, thus surrounded by it, and positioned on the basket-side flange at its rear face, which is adjacent to the mechanical interface. This ensures that the ramp's function is reliably fulfilled and that the sealing element's sealing function is also reliably maintained.

[0024] The respective ramp, particularly in conjunction with the bayonet fitting during the rotation of the loudspeaker basket relative to the support element, initially provides a reduced sealing pressure at the start of assembly – essentially as a starting aid – in the area of ​​the mechanical interface. During the subsequent rotation of the joining process, this reduced pressure then generates the desired or intended contact pressure on the sealing element. Relative to the rotation of the loudspeaker or its speaker basket, the support-side joining contour, preferably in the form of a radial or joining tab, moves along the axially rising (insertion or entry) ramp(s) as the rotation increases. This ramp ensures that, during the joining process, the desired or intended contact pressure on the sealing element is generated until the bayonet fitting is engaged, including locking or securing via the snap-fit ​​connection.

[0025] In other words, the respective ramp is positioned in front of the basket-side joining element in the circumferential direction of the basket-side flange in such a way that, during the rotation of the loudspeaker basket relative to the support element, a reduced sealing pressure is initially generated in the area of ​​the mechanical interface, and, during the further rotation of the loudspeaker basket during the joining process, an increasing contact pressure is generated on the sealing element. Preferably, this is...As the loudspeaker basket rotates, the opening edge of the carrier-side receiving opening, particularly in the area of ​​the carrier-side joining contour, is guided along the respective ramp, wherein the carrier-side joining contour, preferably in the form of the radial or joining tab, engages behind or under the basket-side joining element during the joining process to produce the bayonet closure, generating the desired or intended contact pressure on the sealing element.

[0026] Another aspect of the mounting arrangement or device provides for a water drain, preferably without a tray, at a specific location on the system interface, preferably at the lowest point of the interface, between the loudspeaker basket and the edge of the mounting opening on the support side. A combination of this aspect with a bayonet fitting as the preferred joining connection between the loudspeaker or its loudspeaker basket and the support element of the mounting arrangement or device is particularly suitable.

[0027] A particularly suitable further development provides that the basket-side flange has a receptacle or insertion opening with an inserted connector or plug contact for receiving a mating connector for the loudspeaker, especially for supplying power to the loudspeaker coil. The support element has a locking contour with a recess adapted to the connector or the (cable-side) mating connector, whereby the basket-side plug contact or connector aligns with the support-side recess only in a specific end position of the loudspeaker basket at the opening edge of the support-side receptacle. This serves as a technical safeguard for the plug-in connection of the external (cable-side) connector or mating connector, as it can only be plugged into the basket-side connector if the loudspeaker has been mounted in the intended position and orientation on the support element. This makes it possible to reliably detect and correct assembly errors.Recognizable and avoidable. A combination of these aspects, or of the respective aspect, with the bayonet fitting as the preferred joining connection between the loudspeaker or its loudspeaker basket and the support element of the mounting arrangement or device is particularly suitable.

[0028] This mounting arrangement is particularly suitable for use with a vehicle door module. The support element, made of materials such as plastic or fiber composite, is a component or integral part of a door module mounting plate or inner door panel. The door module mounting plate serves as a carrier for the loudspeaker and other components, especially a door lock and a window regulator or parts thereof. The door module mounting plate, to which the support element is attached or of which it is an integral part, also serves to separate a dry space between the door module mounting plate or inner door panel and the door interior trim from a wet space between the door module mounting plate or inner door panel and the outer door skin (outer door panel).

[0029] The loudspeaker mounted in the carrier-side receiving opening, which is preferably a mid-range or low-midrange loudspeaker based on the moving coil principle, protrudes into the wet room with the bottom of its loudspeaker basket, while the loudspeaker diaphragm is located in the dry room and faces the vehicle interior.

[0030] To prevent water from accumulating in the wet environment around the loudspeaker, the mounting arrangement incorporates a suitable drainage system that avoids the formation of a basin where water could collect. For this purpose, a circular segment of the mounting interface is radially reduced at the lowest point when the loudspeaker is installed, or at a point or position located as low as possible vertically (relative to a vehicle coordinate system in the z-direction of the vehicle). In other words, the circular segment is recessed at the edge of the mounting opening on the carrier side. This carrier-side recess aligns with a basket-side recess or elongated basket opening, which also extends a circular segment and, suitablely, at least slightly radially into the mounting interface.

[0031] In this region of the circular segment, the radial width of the interface is preferably smaller than the radial width of the interface extending circumferentially outside this region. In particular, the carrier-side sealing flange is asymmetrical to the basket- or flange-side sealing area. In other words, the annular surfaces of the carrier-side sealing flange or area and the basket- or flange-side sealing area are offset relative to each other. This prevents an oval shape of the sealing element or seal between the loudspeaker basket and the carrier-side receiving opening or its opening edge.

[0032] On the outer circumference of the mechanical interface of the mounting assembly, on the basket side (i.e., on the flange of the loudspeaker basket), a circumferentially closed axial wall or an axially extending contact collar for the sealing element is provided. The sealing element, preferably with its radially outer sealing lip, rests against this wall or collar. The radially inner circumferential side or annular surface of the sealing element, in particular its radially inner sealing lip, is suitably aligned with the recess on the support side and with the recess on the basket side. In other words, a radially inner, circular segment-like circumferential region of the sealing element arranged on the basket-side flange transitions into the recess on the support side (basket opening) in the area of ​​the basket-side recess (basket opening), preferably as smoothly, steplessly, and / or as seamlessly as possible.

[0033] The advantages achieved with the invention lie particularly in the fact that the interface between the speaker basket and the edge of the mounting opening on the support side, in conjunction with the speaker, exhibits a higher connection stiffness compared to generally accepted connection stiffnesses. Furthermore, the speaker basket is optimized, or can be optimized, for symmetrical loading with regard to acoustic ventilation. Additionally, the symmetrical opening areas of the speaker basket generate a symmetrical flow resistance on the speaker diaphragm, thereby reducing diaphragm wobble. Moreover, by reducing edges and surfaces in the main flow area of ​​the speaker diaphragm, unwanted ventilation noise is avoided and flow losses are reduced.With regard to the carrier-side interface (base carrier interface), a comparatively rigid loudspeaker connection is achieved, which in turn increases the sound quality and improves the impulse response of the loudspeaker system.

[0035] The following information regarding spatial directions is also given specifically in a vehicle coordinate system. The abscissa (X-axis, X-direction) is oriented along the vehicle's longitudinal direction (direction of travel), the ordinate (Y-axis, Y-direction) along the vehicle's transverse direction, and the application axis (Z-axis, Z-direction) along the vehicle's height.

[0036] The Figure 1 and 2The illustration shows a section of a door module 1 of a vehicle door, viewed from a wet room side and a dry room side, respectively. The door module 1 comprises a support element 2, which is made, for example, of plastic or a fiber composite material. The support element 2, which can be a separate component, is, in this embodiment, an integral part of a door module support plate or an inner door panel 3, which is designed and configured as a carrier for a loudspeaker 4 and for other components, in particular components of a window regulator. Components of a window regulator that are partially recognizable include a guide rail 5 with a sliding guide or follower 6 for a window pane (not shown).The rail slider 6 is connected to a traction cable 8 guided over at least one cable pulley 7 on the rail side, which is coupled to an (unseen) electric motor cable drive. The door module support plate 3 also serves to separate the drying room (. Fig. 2 ) between the door module carrier plate 3 on the one hand and a (not shown) inner door panel of the wet room ( Fig. 1 ) between the door module carrier plate 3 and a (not shown) outer door skin on the other hand.

[0037] As in Fig. 2 As can be seen, the loudspeaker 4 is located in a loudspeaker opening of the carrier element 2, subsequently referred to as the carrier-side receiving opening 9. The loudspeaker 4, which is shown here without and in Fig. 3The (loudspeaker) membrane shown has a loudspeaker basket 10 and a connector 11, which is connected to a mating connector 11a on a connecting cable 12 for operating or powering the loudspeaker 4, or is plugged in during assembly.

[0038] Fig. 3Figure 1 shows an exploded view of the assembly arrangement of the loudspeaker 4 and the support element 2, as well as an annular sealing element (sealing ring) 13. The following directional designations, such as an axial direction A and a radial direction R, refer to the plane of a mechanical connection or mounting interface 14 between a flange 15 of the loudspeaker basket 10 and the opening edge 16 of the mounting opening 9 on the support side. The central axis Z of the assembly, consisting of the loudspeaker 4 and the support element 2, runs normal (perpendicular) to the plane of the connection interface 14. For clarity, only a partial representation is shown here. With respect to the vehicle coordinate system, the central axis Z runs in the Y-direction of the vehicle, i.e., in the transverse direction of the vehicle.

[0039] The sealing element 13 is located on the rear side of the flange 15b facing the dry-room-side opening edge 16 of the support-side receiving opening 9 ( Fig. 5The flange 15 of the loudspeaker basket 10, also referred to below as the basket-side flange, is preferably bonded to the basket. The flange 15 has a flange wall 15a extending in the axial direction A, preferably at least partially closed in the circumferential direction of the flange 15 or the loudspeaker basket 10. The annular edge or surface of this wall, facing a basket base 17 of the loudspeaker basket 10, forms the rear flange 15b of the basket flange 15, which faces the opening edge 16 of the support-side receiving opening 9.

[0040] The loudspeaker 4, which is to be mounted in or is mounted in the carrier-side mounting opening 9, is a mid-range or low-midrange loudspeaker based on the moving-coil principle. Its basket base 17, with a permanent magnet 18 mounted to it, projects into the wet area, while a loudspeaker diaphragm 19 is located in the dry area and faces (in the Y direction) towards the vehicle interior. The diameter of the basket-side flange 15 is, for example, approximately 12 cm to 15 cm, and the frequency response of the loudspeaker 4 lies particularly in the range between approximately 40 Hz or 200 Hz and 2 kHz.

[0041] The support element 2 is cup-shaped in the area of ​​the support-side receiving and / or baffle opening 9, with a wall 20 that widens conically into the wet chamber. A molded part 21 with a plug receptacle or plug passage 22 extending in the axial direction A and in the circumferential or tangential direction for the cable-side mating plug 11a is provided on the wall 20. The intended mounting of the loudspeaker 4 requires that the connecting plug 11, inserted into an unspecified receptacle of the flange 15 or its flange wall 15a – in the radial direction R – is aligned with the support-side plug receptacle 22.

[0042] According to the Poka-Yoke principle, a plug connection between the cable-side mating connector 11a and the basket- or speaker-side connector 11 is only possible if the speaker 4 is seated in the carrier-side receiving opening 9 in its intended position or orientation (intended end position). The carrier-side connector receptacle or feedthrough 22, as a recess adapted to the connector 11 or the mating connector 11a, thus forms a kind of locking contour such that the basket-side connector or plug contact 11 aligns with the carrier-side recess 22 only in the intended position or intended end position of the speaker basket 10 in the carrier-side receiving opening 9.

[0043] The loudspeaker basket 10, which opens into the drying chamber in the mounting arrangement, has a number of basket or wall struts or webs 23 extending from the basket base 17 to the flange 15. With respect to the preferably annular flange 15 and the circular receiving opening 9 on the support side, as well as to the axis Z normal to these, the basket struts (wall or basket webs) 23 extend approximately in a star shape, i.e., are oriented radially in the direction R. The basket struts or webs 23 can also extend from the basket base 17 towards the basket-side flange 15 at an angle. The basket base 17 and the flange 15 can be axially offset from each other.

[0044] The basket struts 23 are formed between elongated basket or through-openings 24, which extend in an arc around the circumference of the loudspeaker basket 10. This hole-strut structure consisting of the basket openings 24 and the basket struts 23 can be arranged in the basket base 17 or between it and the basket flange 15.

[0045] At least some of the basket struts 23 are each formed with an integral joining element 25. These basket-side joining elements 25 correspond to joining contours 26 on the support side to create a bayonet closure. The basket-side joining elements 25 have a claw-like hook structure or function as claws or locking hooks or claws. The support-side joining contours 26 are designed as radial tabs that are integrally formed on the support element 2 in the area of ​​the opening edge 16 of the support-side receiving opening 9 and extend radially R into the receiving opening 9.

[0046] During the mounting of the loudspeaker 4 on the support element 2, the loudspeaker basket 10 extends through the receiving opening 9 on the support element, so that the basket-side flange 15 rests against the rear edge 16 of the receiving opening 9 with the sealing element 13 interposed. The sealing element 13, which serves to seal the loudspeaker 4 or its basket 10 against the support element 2, preferably covers the entire interface 14.

[0047] As shown below, based on the Figures 9 to 12 further explained, and in particular based on the Fig. 9As illustrated relatively clearly, the bayonet fitting, used to connect the loudspeaker 4 or its basket 10 to the support element 2, is created by first inserting it in the axial direction A along the (rotational) axis Z normal to the interface plane, followed by a rotational movement about this axis Z, in this embodiment counterclockwise. The interface plane is the plane of the connection interface 14 between the receiving opening 9 on the support side and the flange 15 on the basket side.

[0048] During the manufacture of the bayonet fitting, and specifically during the rotation of the loudspeaker 4 or its loudspeaker basket 10 relative to the support element 2, the basket-side joining element 25 engages the support-side joining contours 26 in the area of ​​the mechanical contact or connection interface 14 of the mounting arrangement. In this process, the respective support-side joining contour 26 engages behind or underneath the associated basket-side joining element 25 during the rotation of the loudspeaker basket 4 relative to the support element 2.

[0049] The Figures 4 to 6 show the loudspeaker basket 10 with a view into it or with a view to the rear flange 15b of the flange 15 facing the system interface 14 with the ( to be arranged there) Fig. 5 ) or preferably a sealing element 13 that is bonded to the material.

[0050] As in Fig. 4 and especially in Fig. 6As is relatively clearly visible, the basket-side joining elements 25 have a groove-like locking recess or locking contour 27 into which a groove-like inlet ramp 28 opens. These locking contours 27, which are connected to (pin-like) locking elements 29 ( Fig. 8 ) on the carrier-side joining contours (radial tabs) 26, serve to create a snap connection at the end of the rotational movement of the loudspeaker 4 or its loudspeaker basket 10 relative to the carrier element 2, in order to lock the bayonet closure, preferably releasably.

[0051] The sealing element 13 has two concentric sealing lips 13a, 13b, with the radially outer sealing lip 13a projecting axially beyond the radially inner sealing lip 13b. The sealing element 13 is designed as a two-component seal, with the radially inner sealing lip 13b being a comparatively hard or rigid sealing component, while the radially outer sealing lip 13a is a comparatively soft sealing component. An axial rib 30 is provided on the rear flange 15b of the basket-side flange 15 as a circumferential contact collar, against which the radially outer sealing lip 13a rests on its outer circumference, or against which the sealing element 13 is supported in the radial direction R.

[0052] In the area of ​​the connector 11, a spring element 31 with a central locking dome 32 is provided on the flange 15 on the rear side for further locking of the loudspeaker 4 with the support element 2 ( Fig. 8 ).

[0053] On the flange 15 of the loudspeaker basket 10, on the rear side 15b of the flange facing the opening edge 16 of the receiving opening 9, ramps (launch ramps) 33 extending circumferentially around the basket-side flange 15, in particular arc-shaped ramps (launch ramps) 33 are provided. The ramps 33 extend only over a limited arc or arc segment, preferably with a central angle of the radii of the arc between 10° and 30°, more suitablely between 15° and 20°.

[0054] The ramps 33 serve to generate a contact force on the sealing element 13 during the rotational movement in the process of forming the bayonet fitting between the loudspeaker 4 or its loudspeaker basket 10 and the support element 2. Each ramp 33 is located in the area of ​​the interface 14 between the receiving opening 9 on the support element and the sealing element 13, and is thus positioned radially inwards towards the sealing element 13. This ensures the proper function of the ramp 33 and also guarantees a reliable seal. Furthermore, the ramps 33 simplify the mounting of the loudspeaker 4 on the support element 2.

[0055] During the rotational movement of the loudspeaker basket 10 relative to the support element 2, particularly during the manufacture of the bayonet closure, the ramps 33 in the area of ​​the mechanical mounting or connection interface 14 provide a starting aid by initially generating a reduced sealing pressure at the start of assembly and, during the further rotational movement during the joining process, generating the intended contact pressure on the sealing element 13.

[0056] As the loudspeaker 4 or its basket 10 rotates, the carrier-side joining contours 26 reliably move along the insertion or entry ramps 33 under or behind the basket-side joining elements 25 until the bayonet closure is formed, including the locking or locking by means of the snap connection between the carrier-side locking elements or locking pins 29 and the basket-side locking recesses 27. The respective ramp 33 is arranged upstream of the basket-side joining element 25 in such a way that, during the rotation of the loudspeaker basket 10, a reduced sealing pressure is initially generated in the area of ​​the mechanical contact or connection interface, and, during further rotation of the loudspeaker 4 or the loudspeaker basket 10, an increasing contact pressure is generated on the sealing element 13.

[0057] To prevent water from accumulating in the wet area around the loudspeaker 4, a suitable water drain W is provided, avoiding the formation of a basin in which water could collect. The water drain W is conveniently located at the lowest point P, meaning at the lowest point (in the Z-direction of the vehicle) of the mounting interface 14 between the loudspeaker basket 10 and the opening edge 16 of the carrier-side receiving opening 9. For this purpose, one of the basket openings 24 is designated as a basket-side recess 24', which extends over a circular segment and slightly radially into the basket-side mounting interface 14.

[0058] In the area of ​​these basket openings or basket-side recesses 24', the radial width of the flange back 15b is smaller than the radial width of the flange back 15b extending circumferentially outside this area. At this point, in the area of ​​the lowest point P, the basket-side flange 15 transitions directly, meaning without edges or steps, into the basket-side recess 24' ( Fig. 4 ).

[0059] The Figures 7 and 8 show the support element 2 in various perspective representations, whereby Fig. 7 the support element 2 from the rear side facing away from the loudspeaker 4 (wet room side) and Fig. 8 the support element 2 is shown from the system or mounting side (dry room side) facing the loudspeaker 4. In Fig. 7 The carrier-side locking pins 29 are recognizable on the joining contours 26 of the carrier element 2, which are designed as radial lugs.

[0060] Fig. 9The exploded view shows an assembly state during or at the beginning of the insertion movement of the loudspeaker 4 or its basket 10 in axial direction A and along the (central) insertion and rotation axis Z into the carrier-side receiving opening 9.

[0061] The Figures 10 and 11 The perspective views of the rear (wet room side) and the front (dry room side) show the mounting arrangement of the loudspeaker 4 or its basket 10 on or on the support element 2 with the bayonet closure in place, including the locking connection between the basket-side and support-side locking elements 27 and 29, respectively.

[0062] In the Figures 7 and 8 Circular arc-shaped cutouts 34 are visible between the joining contours 26 on the carrier side. InThese carrier-side cutouts 34 engage the basket-side joining elements 25 during the insertion movement in the process of forming the bayonet fitting. The carrier-side cutouts 34 provide different arc lengths by forming circular segments of the cutouts 34 with additional radial struts or tabs 35, which project into the carrier-side receiving opening 9 within certain cutouts 34 and are integrally formed with the circumferential wall 16. This ensures that, during the insertion movement, there is only one intended or possible insertion position for the respective basket-side joining element 25 of the loudspeaker basket 10 into these carrier-side cutouts or recesses 34.

[0063] In Fig. 8In the area of ​​the molded part 21 of the carrier element 2, a groove-like detent 37 with a (central) detent groove 38 is visible. During the manufacture of the bayonet closure, the carrier-side detent 37 receives the basket-side spring element 31, whereby, for an additional detent connection of the loudspeaker 4 or its basket 10, the detent dome 32 of the basket-side spring element 31 engages in the detent groove 38 of the carrier-side detent 37.

[0064] At the lowest point P, meaning at the lowest possible location or position of the support element 2, a circular segment-shaped recess 36 for water drainage W is provided at the opening edge 16 of the support-side receiving opening 9. This support-side recess 36 is aligned with the basket-side recess 24', which also extends over a circular segment and, suitably, at least slightly radially into the interface 14. In this area of ​​the support-side recess 36, the radial width of the interface 14 is smaller than the radial width of the annular interface 14 extending circumferentially outside this area.In other words, in this area of ​​the carrier-side recess 36, the radial width of the circumferential edge 16 of the carrier-side receiving opening 9 is smaller than the radial width of the (ring) section of the carrier-side circumferential edge 16 of the receiving opening 9 extending outside this area.

[0065] As from the Figures 10 and 11 As can be seen, in the assembled configuration, the radially inner circumferential side or surface of the sealing element 13 or its radially inner sealing lip 13b is aligned with the support-side recess 36 and with the basket-side recess 24' in the area of ​​the lowest point P for providing the water drainage W. A radially inner circular segment-shaped circumferential region of the sealing element 13 arranged on the basket-side flange 14 transitions as smoothly, steplessly, and / or as seamlessly as possible into the support-side recess 36 in the area of ​​the basket-side recess 24'.

[0066] Fig. 12 The section view shows the joining area with the snap connection between one of the basket-side joining elements 25 and the corresponding joining contour 26 on the support side, as well as the contact of the sealing element 13 at the mechanical contact interface 14 between the mounted loudspeaker 4 or its basket 10 and the support element 2 with the bayonet closure in place.

[0067] By the design of the opening edge 16 of the support-side receiving opening 9 and of the basket-side flange 15 on its rear flange 15b, in particular by means of axial centering pins 39 provided there, which are in the Figures 5 and 9 As can be seen relatively clearly, during the manufacture of the bayonet fitting, especially during the insertion movement (plug-in assembly) of the loudspeaker 4, a self-centering of the loudspeaker 4 or its basket 10 in the carrier-side receiving opening 9 takes place.

[0068] The radially inner sealing lip 13b acts as a radial sealing element (in radial seal R) and also as a centering element during the (plug-in) assembly of the loudspeaker 4 or its loudspeaker basket 10 into the receiving opening 9 of the support element 2, particularly in the area of ​​the interface 14. The radially outer, axially projecting sealing lip 13a, as a soft sealing component compared to the radially inner sealing lip 13b, acts as an axial sealing element (in axial seal A) to seal the loudspeaker 4 against the support element 2 in the area of ​​the interface 14.

[0069] In summary, the invention relates to a mounting arrangement for a loudspeaker 4, particularly in a vehicle door. For this purpose, a support element 2 with a receiving opening 9 for the loudspeaker 4 and a loudspeaker basket 10 with a flange 15, as well as a sealing element 13 in the area of ​​a mechanical interface 14 between the loudspeaker basket 10 and the support element 2, are provided. During assembly, the loudspeaker basket 10 passes through the receiving opening 14 on the support element 2, and the basket-side flange 15 rests against the support element 2 with the sealing element 13 interposed. To create a bayonet fitting or a plug-and-twist connection of or within the mounting arrangement, the loudspeaker basket 10 has a number of joining elements 25, arranged in particular on basket struts 23 of the loudspeaker basket 10, which correspond to joining contours 26 of the support element 2.

[0070] Additionally, at least one ramp 33, preferably circular arc-shaped, is provided on the flange 15 on the side 15b facing the system interface 14 of the basket side, to generate a contact force on the sealing element 13. This ramp extends in particular in the circumferential direction of the flange 15 on the basket side and is provided to generate a contact force on the sealing element 13. Furthermore, a water drain W, preferably without a tray, can be provided, particularly at a lowest point P of the system interface 14, between the loudspeaker basket 10 and the system interface 14 of the support-side receiving opening 9. Furthermore, a plug receptacle or feedthrough 22 can be provided on a molded part 21 of the support element 2 such that – preferably according to the Poka-Yoke principle – a plug connection of an external mating plug 11a with a basket- or loudspeaker-side connector 11 is only possible when the loudspeaker 4 or the loudspeaker 4 is connected to the support element 14.whose basket 10 is seated in the carrier-side receiving opening 9 in a designated target position or target position (target end position).
