Loudspeaker mounting arrangement in a motor vehicle

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 mounting arrangement, preferably in the manner of a bayonet catch, of a loudspeaker on a carrier element of the motor vehicle.

DE 101 44 665 B4 discloses a vehicle door with an inner door panel as a wall, to which a loudspeaker is attached. The wall has a receiving opening into which the loudspeaker is inserted and attached to the wall by means of screws, rivets or the like. In a lower section from the speaker and there within the speaker basket and below a local mounting axis, a water drain is provided in a wet room, which is separated by the wall of a drying room of the vehicle door.

DE 20 2005 014 605 U1 discloses a vehicle door with a wall facing the interior of the vehicle and having a receiving opening for a loudspeaker. In the area of the receiving opening or on the loudspeaker, integral fastening means are provided which, together with receiving means, form a plug-in connection designed as a latching or clip connection, a bayonet connection or a threaded connection.

The invention is based on the object of specifying a particularly suitable mounting arrangement or mounting device for a loudspeaker of a motor vehicle, in particular in a vehicle door of the motor vehicle. In particular, the loudspeaker should be as simple as possible, preferably also while avoiding assembly errors (poke yoke), securely on a support element (base support), in particular as a wall for the loudspeaker or its loudspeaker basket or generally the loudspeaker housing, be mountable, particularly before given to screws without additional fastening means, such as fastening, rivets, a fastening ring or the like are required. Furthermore, a particularly suitable door module with such a mounting arrangement should be specified.

With regard to the assembly arrangement, the stated object is achieved with the features of claim and with regard to the door module with the features of claim 16 according to the invention. Advantageous refinements and developments are the subject matter of the dependent claims (subclaims).

The mounting arrangement or mounting device for a loudspeaker or for a loudspeaker of a motor vehicle, in particular in a vehicle door, has a carrier element with a receiving opening, surrounded by an opening edge, for the loudspeaker. The carrier element preferably serves as a base carrier and is expediently a component or an integral part of a carrier plate installed in a vehicle door (door module carrier plate) or a plate-like door module carrier, for example designed as a plastic part, which is suitable for separating a wet room and a dry room of the Vehicle door is used, or is a component that can be connected to a door inner panel. The support element can also serve as a baffle for the loudspeaker, and the receiving opening can also be a baffle opening.

“Mounting arrangement or device” also means a fastening structure for mounting a loudspeaker on a base support or door module support (unit or component support) of a motor vehicle door, in particular a door module or for such a door module.

“Loudspeaker” is understood here and in the following to mean a sound transducer, in particular based on the cloth coil principle (moving coil loudspeaker), with a membrane and with a drive unit and with connecting elements. In particular, the speaker has a speaker basket, a membrane (loudspeaker membrane), a surround (rubber surround), a spider, a voice coil and a permanent magnet. The membrane is typically connected by means of the bead to a flange and via the spider to, for example, conically running wall or basket struts in the area of the basket bottom of the loudspeaker basket. The membrane is driven by the centrally mounted voice coil, which oscillates in the magnetic field of the permanent magnet on the bottom of the basket, so that the membrane is set in motion and guided by the spider. In particular, the loudspeaker is a low-mid or mid-range loudspeaker with a basket flange diameter of, for example, 12 cm to 15 cm and with a frequency response of in particular 40 Hz or 200 Hz to 2 kHz.

The carrier-side receiving opening is designed, for example, in the shape of a cup or conical, in particular with a drawn-in or deep-drawn wall. “Carrier-side receiving opening” is understood here and in the following to mean that the receiving opening is part of the carrier element.

The mounting arrangement or mounting device also has a speaker basket with a flange and with wall or basket braces between the flange and a basket floor. The basket struts form a basket wall which is preferably interrupted in the circumferential direction of the loudspeaker basket, ie which is not or at least not completely closed on the circumferential side. In relation to a preferably annular flange and a circular receiving opening on the carrier side and an axis normal to this, the cage struts can extend at an angle of inclination, starting from the flange to the cage base, with the cage base serving as a mechanical contact or connection interface on the rear side of the flange ( Flange back) can be axially offset.

The loudspeaker frame is preferably shaped approximately like a pot, with its flange being formed as an axially extending flange wall which is expediently at least partially closed on the peripheral side. Between this and the basket bottom or in this is a hole-bar structure with extending in the circumferential direction, expediently arcuate or slot-like, Through openings provided between which the basket or wall struts are formed.

The assembly arrangement or assembly device also has a sealing element. This is used to seal the speaker or its speaker core BES relative to the support member. The sealing element is provided in the area of a contact or connection interface between the loudspeaker basket, in particular its flange, and the opening edge of the receiving opening. The sealing element is expediently bonded to the loudspeaker frame and there to its flange. The sealing element surrounds the system interface in a suitable manner completely or completely.

In the course of mounting the loudspeaker on the support element, the basket bottom of the loudspeaker basket extends through the support-side receiving opening in such a way that the basket-side flange rests on the rear flange of the opening edge of the receiving opening with the interposition of the sealing element. In other words, the mounting arrangement is designed in such a way that during the installation of the loudspeaker on the carrier element, the flange side of the basket-side flange (rear flange side) facing the bottom of the loudspeaker basket comes into contact with the opening edge of the recess on the carrier side, with the sealing element being interposed. “Flange on the basket side” is understood here and in the following to mean that the flange is part of the loudspeaker basket.

In the case of a carrier element which separates a dry space facing the vehicle interior from a wet space (towards the outer skin of the door) in a vehicle door, the basket floor and the wall or basket struts of the loudspeaker basket are in the wet space, while the flange of the loudspeaker is in the dry space is located and the membrane of the speaker faces the front of the vehicle interior.

In an advantageous embodiment, the loudspeaker frame has a number of elements to be joined. These correspond to the carrier-side joining contours, in particular to tabs (radial tabs), webs or ribs that protrude into the receiving opening or point radially inward or are oriented in the radial direction Creation of a bayonet lock as a combined push-turn connection. The mounting arrangement thus enables a particularly simple and reliable connection of the loudspeaker or its basket to the support element without additional fastening means, such as screws, rivets, locking or clip elements or a fastening ring. “Carrier-side joining contour” is understood here and in the following to mean that the joining contour is part of the carrier element.

The term "bayonet lock" is used here and in the following to mean a joint connection of the loudspeaker or its loudspeaker basket or loudspeaker housing with the support element by means of a combined plugging and turning movement, with initially a movement along a plane normal to the interface level (rotational ) Axis and then the rotary motion occurs around this axis, for example in the manner of a screw cap.

The interface plane is the plane of the abutment interface between the carrier-side receiving opening and the basket-side flange.

According to an expedient development of the joint connection between the loudspeaker or its loudspeaker basket and the carrier element at the attachment interface of the bayonet lock, the basket-side joining element has claw-like hook or lock structures as integral fastening means of the loudspeaker basket, which during the manufacture of the bayonet lock have the corresponding carrier-side Joining contours overlap as integral fasteners of the carrier element in the area of the system 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 below the associated basket-side joining element during the rotational movement of the loudspeaker basket relative to the support element. This is expediently a locking hook that is formed on the speaker basket and there preferably on the corresponding basket or wall strut. “Basket-side joining element” is understood here and in the following to mean that the joining element is part of the loudspeaker basket. In an advantageous embodiment, a locking connection is formed between at least one of the basket-side joining elements and the corresponding support-side joining contour when the bayonet catch between the loudspeaker basket and the support element is made or is being made. At least one of the joining elements on the basket side suitably has a latching contour, and the joining contour on the carrier side has a corresponding latching element which, in the course of manufacturing the bayonet connection between the loudspeaker basket and the carrier element, fits into the latching contour on the basket side, particularly preferably via one that opens into the latching contour on the basket side infeed ramp, intervenes.

According to a particularly advantageous development, arc-shaped cutouts and/or at least one axial bracket are provided on the flange on the basket side between the joining contours on the carrier side. The carrier-side sections are provided for receiving the basket-side joining elements during a plug-in movement during the manufacture of the bayonet catch between the speaker basket and the support element. The carrier-side cutouts provide different circular arc lengths, for example through additional radial struts in the cutouts, so that only one single possible insertion position of the loudspeaker basket into the carrier-side recess is given for the production of the bayonet closure during the plugging movement. Additionally or alternatively, the axial brackets on the basket side can prevent the loudspeaker or its basket from being plugged in incorrectly or unintentionally. As a result, assembly errors, in particular according to the Poka-Yoke principle for direct error detection, are reliably avoided.

In an expedient embodiment, the sealing element is designed with a soft sealing component and with a comparatively hard or rigid sealing component as a 2K seal or 2K sealing ring (two-component seal or sealing ring). The sealing element suitably has two concentric sealing lips, one of the sealing lips, in particular a radially outer sealing lip, projecting axially beyond the other sealing lip. The radially inner of these sealing lips, which is expediently designed as a comparatively hard or rigid sealing component, advantageously serves as a radial sealing element (radial seal) and in particular as a centering element during (plug-in) assembly of the Loudspeaker or its basket in the receiving opening of the support element in the area of the connection or system interface. The radially inner sealing lip thus preferably assumes a dual function. The radially outer, axially overhanging 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 carrier element.

A further aspect of the mounting arrangement or mounting device provides that on the flange of the loudspeaker basket on the flange side (flange rear side) facing the opening edge of the receiving opening there is a ramp (starting ramp) running in the circumferential direction of the basket-side flange, in particular in the shape of a circular arc. This ramp suitably extends only over a limited arc of a circle or section of a circular arc, in particular with a center angle of the radii of the arc of a circle between 10° and 30°, preferably between 15° and 20°.

Suitably there are several, preferably three, ramps on the basket side flange. The respective ramp is used to generate a pressing force on the sealing element, in particular during the rotary movement in the course of producing the bayonet connection between the loudspeaker or its loudspeaker basket and the carrier element. The respective ramp is suitably arranged in front of an associated joining element on the basket side in such a way that during the manufacture of the bayonet lock during plug-in assembly of the loudspeaker or its basket, the support-side joining contour or radial tab is in the same radius area as the basket-side ramp.

The respective ramp is particularly expediently provided in the area of the contact interface between the support-side receiving opening and the sealing element. In other words, the respective ramp is expediently located radially inward of the sealing element, i.e. it is surrounded by it and is arranged on the cage-side flange on its rear flange facing the mechanical contact interface . This ensures that the function of the ramp is reliable fulfilled and at the same time the sealing function of the sealing element is reliable.

The respective ramp allows, especially in connection with the bayonet connection during the rotary movement of the speaker basket relative to the carrier element, in the area of the mechanical contact interface initially - quasi as a starting aid - a reduced sealing pressure at the start of assembly and in the course of the further rotary movement during the joining process, the generation of the ge desired or intended contact pressure on the sealing element. Relative to the rotary movement of the loudspeaker or its loudspeaker basket, the support-side joining contour in the form of preferably the radial or joining tab runs along the axially rising (insertion or inlet) ramp(s) with increasing rotary movement, in order to in the course of the joining connection up to the production of the Bajo nice closure, in particular including a locking or locking means of the locking connection to generate the desired or the intended contact pressure on the sealing element.

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 as the loudspeaker basket rotates relative to or relative to the carrier element in the area of the mechanical contact interface, there is initially a reduced sealing pressure and then as the Rotational movement of the speaker basket during the joining process, an increasing contact pressure on the sealing element is generated or is. Preferably, the opening edge of the support-side receiving opening, in particular in the area of the support-side joining contour, is or will be guided along the respective ramp with increasing rotary movement of the loudspeaker basket, the support-side joining contour preferably being in the form of the radial or joining bracket in the course of the joining connection for manufacture tion of the bayonet catch engages behind or below the basket-side joining element, generating the desired or intended contact pressure on the sealing element.

Another aspect of the mounting arrangement or mounting device provides that at a specific location of the system interface, preferably at a lowest point of the system interface, between the loudspeaker frame and the opening edge of the support-side receiving opening, a water drain is provided, in particular when there is no water. This aspect, like the aspect of the ramp(s) on the basket-side flange, represents an independent invention. A combination of these aspects or the respective aspect with the bayonet catch is particularly suitable as the preferred joint connection between the loudspeaker or its loudspeaker basket and the support element of the mounting arrangement tion or device.

A particularly suitable further development provides that the basket-side flange has a receptacle or joining opening with a connecting plug or plug-in contact inserted therein for receiving a mating plug for the loudspeaker, in particular for energizing the loudspeaker coil. The carrier element has a locking contour with a recess adapted to the connector plug or to the (cable-side) mating connector, with the basket-side plug contact or connector plug being aligned with the carrier-side recess only in a target end position of the loudspeaker basket at the opening edge of the carrier-side receiving opening. This serves as a technical precaution for plug-in contacting of the external (cable-side) connector or mating connector, in that it can only be plug-contacted with the connector on the basket side if the loudspeaker has been installed in the intended position and location on the support element. As a result, assembly errors can be reliably found or recognized and avoided. This aspect also represents an independent invention. A combination of these aspects or the respective aspect with the bayonet catch is particularly suitable as the preferred joining connection between the loudspeaker or its loudspeaker basket and the support element of the assembly arrangement or device.

The assembly arrangement is particularly suitable in connection with a door module of a motor vehicle. In this case, the support element made of plastic or a fiber composite material, for example, is a component or an integral part of a door module support plate or an inner door panel. The Türmodulträ gerplatte serves as an aggregate or component carrier for the speaker as well as for other components, especially for a door lock and for a window regulators or components thereof. The door module carrier plate to which the carrier element is attached or of which it is an integral part is also used in particular to separate a dry space between the door module carrier plate or the inner door panel and a door inner panel from a wet area between the door module carrier plate or the inner door panel and an outer door skin (outer door panel).

The speaker mounted in the carrier-side receiving opening, which is preferably a mid-range or low-mid-range speaker based on the moving coil principle, protrudes into the wet area with the bottom of its speaker basket, while the speaker membrane is in the dry area and faces the vehicle interior.

To avoid water accumulating on the loudspeaker in the wet area, the assembly arrangement has a suitable water drain, avoiding the formation of a trough in which water could collect. For this purpose, a segment of a circle of the system interface is reduced in the radial direction at a lowest point when the loudspeaker is installed or at a point or position which is provided as far down vertically as possible, based on a vehicle coordinate system in the z direction of the motor vehicle. In other words, the segment of a circle is cut out at the edge of the carrier-side receiving opening. This carrier-side recess is aligned with a basket-side recess or slot-like basket opening, which likewise extends over a circle segment and suitably at least slightly radially into the contact interface.

In this area of the circle segment, the radial width of the contact interface is preferably smaller than the radial width of the contact interface extending in the circumferential direction outside of this area. In particular, the carrier-side sealing flange is asymmetrical to the cage 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 mutually displaced. As a result, an oval shape of the sealing element or the seal between the loudspeaker frame and the carrier-side receiving opening or the opening edge is avoided.

On the outer circumference of the mechanical contact interface of the assembly arrangement, a circumferentially preferably completely, but at least partially, closed axial wall or a contact collar extending in the axial direction for the sealing element is provided on the basket side, ie on the flange of the loudspeaker basket. The sealing element lies against this or against this, preferably with the radially outer sealing lip. The radially inner peripheral side or annular surface of the sealing element, in particular its radially inner sealing lip, is aligned appropriately with the carrier-side recess and with the basket-side recess. In other words, a radially inner circular segment-like circumferential area of the sealing element arranged on the cage-side flange in the area of the cage-side recess (cage opening) transitions into the carrier-side recess, preferably as transitionally, steplessly or edgelessly and/or flatly as possible.

The advantages achieved by the invention are, in particular, that the system interface (loudspeaker interface) between the loudspeaker basket and the opening edge of the carrier-side receiving opening in connection with the loudspeaker represents a higher connection rigidity compared to the generally customary connection rigidities. In addition, the speaker basket is optimized or can be optimized with regard to acoustic ventilation towards a symmetrical load. Furthermore, the most symmetrical opening areas of the speaker basket create a symmetrical flow resistance on the speaker membrane, which reduces "wobbling" of the membrane. Furthermore, unwanted ventilation noise is avoided and flow losses are reduced by reducing the edges and surface area in the main flow area of the loudspeaker membrane. With regard to the carrier-side interface (base carrier interface), a comparatively stiff loudspeaker connection is achieved, which in turn increases the sound quality and improves the impulse fidelity of the loudspeaker system.

Corresponding parts and sizes are given the same reference numbers in all figures. Information regarding the spatial directions is given below, also in particular in a coordinate system of the motor vehicle (vehicle coordinate system). The abscissa axis (X-axis, X-direction) is along the longitudinal direction of the vehicle (driving direction) and the ordinate axis (Y-axis, Y-direction) is along the vehicle transverse direction, as well as the application axis (Z-axis, Z-direction) oriented along the vehicle height.

Figures 1 and 2 show a detail of a door module 1 of a vehicle door of a motor vehicle with a view of a wet room side and a dry room side. The door module 1 includes a carrier element 2, which consists for example of plastic or a fiber composite. The carrier element 2, which can be a separate component, is an integral part of a door module carrier plate or an inner door panel 3 in the exemplary embodiment, which is provided as an aggregate or component carrier for a loudspeaker 4 and for other components, in particular for components of a window regulator and set up. Components of a window lifter that can be recognized to some extent are a guide rail 5 with a rail slider or driver 6 for a window pane (not shown) that is guided therein so that it can be slid. The rail slider 6 is connected to a pull rope 8 that runs over at least one rail-side rope pulley 7 and is coupled to a (not visible) electromotive rope drive. The door module support plate 3 also serves to separate the dry space (Fig. 2) between the door module support plate 3 on the one hand and a (not shown) door inner panel from the wet space (Fig. 1) between the door module support plate 3 and a (not shown) door outer skin on the other hand.

As can be seen in FIG. 2, the loudspeaker 4 sits in a loudspeaker opening of the carrier element 2, which is referred to below as the carrier-side receiving opening 9. The loudspeaker 4, which is shown here without and in FIG. 3 with a (loudspeaker) membrane, has a speaker basket 10 and a connector plug 11, which is connected to a mating connector 11a on a connecting cable 12 for operating or for energizing the speaker 4 or is plug-contacted during assembly. Fig. 3 shows an exploded view of the assembly arrangement of the loudspeaker 4 and the carrier element 2 as well as an annular sealing element (sealing ring) 13. Below are directional information, such as an axial direction A and a radial direction R, on the level of a mechanical connection or system Interface 14 between a flange 15 of the loudspeaker frame 10 and the opening edge 16 of the carrier-side receiving opening 9 related. Normal (perpendicular) to the plane of the connection interface 14 runs the central axis Z of the assembly arrangement made up of the loudspeaker 4 and the carrier element 2, which is only partially shown here for a better overview. In relation to the vehicle coordinate system, the central axis Z runs in the Y direction of the Motor vehicle, ie in the vehicle transverse direction.

The sealing element 13 is attached to the rear flange 15b (FIG. 5) of the basket flange 15 of the loudspeaker basket 10, also referred to below as the basket-side flange, which faces the dry space-side opening edge 16 of the carrier-side receiving opening 9, preferably in a materially bonded manner. The flange 15 has a flange wall 15a which extends in the axial direction A and is preferably at least partially closed in the circumferential direction of the flange 15 or the loudspeaker frame 10. Its ring-shaped wall edge or ring surface, which is directed towards a basket bottom 17 of the loudspeaker basket 10, forms the rear flange side 15b of the basket flange 15, which faces the opening edge 16 of the carrier-side receiving opening 9.

The speaker 4 to be mounted in the carrier-side receiving opening 9 or mounted therein is a mid-range or low-mid-range speaker based on the diving coil principle, the basket bottom 17 of which protrudes into the wet room with a permanent magnet 18 mounted thereon, while a speaker membrane 19 is located in the dry room and ( in the Y-direction) faces the vehicle interior. The diameter of the flange 15 on the basket side is, for example, approximately 12 cm to 15 cm and the frequency response of the loudspeaker 4 is in particular in the range between approximately 40 Hz or 200 Hz and 2 kHz.

The carrier element 2 is cup-like in the area of the carrier-side receiving and/or sound wall opening 9 with a conically widening into the wet area Wall 20 running. On the wall 20 there is a molded part 21 with a plug receptacle or plug bushing 22 extending in the axial direction A and in the circumferential or tangential direction for the mating plug 11a on the cable side. Proper assembly of the loudspeaker 4 requires that the connector plug 11 inserted into a receptacle of the flange 15 or its flange wall 15a—in the radial direction R—aligns with the plug receptacle 22 on the carrier side.

According to the poka-yoke principle, plug-in contacting of the cable-side mating connector 11a with the basket-side or speaker-side to connection plug 11 is thus only possible if the speaker 4 is in the wearer-side receiving opening 9 in an intended target position or target location ( Target end position) is seated. The carrier-side plug receptacle or bushing 22 as a recess adapted to the connector plug 11 or to the mating connector 11a thus forms a locking contour, so to speak, such that the basket-side connector or plug contact 11 with the carrier-side recess 22 is only in the desired position or setpoint -End position of the speaker basket 10 in the carrier-side receiving opening 9 is aligned.

The in the mounting arrangement in the drying room opening speaker basket 10 has a number of basket or wall struts or webs 23 extending from the basket bottom 17 to the flange 15 out. Relative to the preferably annular flange 15 and the carrier-side circular Aufnahmeöff opening 9 and the normal axis Z for this, the basket struts (wall or basket webs) 23 extend approximately in a star shape, so are in the radial direction R orien benefits. The basket struts or webs 23 can also run at an angle of inclination, starting from the basket floor 17 in the direction of the flange 15 on the basket side.

The basket bottom 17 and the flange 15 can be axially offset from one another.

The basket struts 23 are formed between slot-like basket or through-opening gene 24, which extend in an arc in the circumferential direction of the loudspeaker basket 10. This hole-strut structure of the basket openings 24 and the basket struts 23 can be arranged flange 15 in the basket bottom 17 or between it and the basket. A joining element 25 is formed onto at least some of the basket struts 23 . These joining elements 25 on the basket side correspond to joining contours 26 on the carrier side for fixing a bayonet catch. The basket-side joining elements 25 have a claw-like flake structure or act as claws or locking hooks or claws. The carrier-side joining contours 26 are designed as radial tabs, which are formed on the carrier element 2 in the region of the Publ voltage edge 16 of the carrier-side receiving opening 9 and extend in the radial direction R into the receiving opening 9 .

In the course of mounting the loudspeaker 4 on the support element 2, the loudspeaker basket 10 passes through the support-side receiving opening 9, so that the basket-side flange 15 rests on the opening edge 16 of the receiving opening 9 with the sealing element 13 being interposed. The sealing element 13, which is used to seal off the loudspeaker 4 or its basket 10 in relation to the carrier element 2, preferably covers the contact interface 14 completely.

As is further explained below with reference to FIGS. 9 to 12, and in particular is illustrated comparatively clearly with reference to FIG. that first an insertion process in the axial direction A along the (rotational) axis Z normal to the interface plane and then a rotational movement about this axis Z takes place, counterclockwise in the exemplary embodiment. The interface level is the level of the connection interface 14 between the carrier-side receiving opening 9 and the basket-side flange 15.

When the bayonet catch is released and during the rotary movement of the loudspeaker 4 or its loudspeaker basket 10 relative to the carrier element 2, the basket-side joining element 25 engages over the carrier-side joining contours 26 in the area of the mechanical contact or connection interface 14 of the assembly arrangement. In this case, the respective carrier-side joining contour 26 engages behind or below during the rotary movement of the Loudspeaker basket 4 opposite the carrier element 2, the associated korbsei term joining element 25.

Figures 4 to 6 show the loudspeaker basket 10 with a view into it or with a view of the flange rear side 15b of the flange 15 facing the contact interface 14 with the sealing element 13 to be arranged there (Fig. 5) or preferably fastened with a material connection.

As can be seen comparatively clearly in FIG. 4 and in particular in FIG. 6, the joining elements 25 on the basket side have a bead-like latching depression or latching contour 27 into which a groove-like inlet ramp 28 opens. These latching contours 27, which interact with (peg-like) latching elements 29 (FIG. 8) on the joining contours (radial tabs) 26 on the carrier side, serve to produce a latching connection at the end of the rotary movement of the loudspeaker 4 or its loudspeaker basket 10 relative to the carrier element 2 to lock the bayonet catch, preferably releasably.

The sealing element 13 has two concentric sealing lips 13a, 13b, the radially outer sealing lip 13a protruding axially from the radially inner sealing lip 13b. The sealing element 13 is designed as a 2K seal, with the radially inner sealing lip 13b being designed as a comparatively hard or rigid sealing component, while the radially outer sealing lip 13a is a comparatively soft sealing component. On the flange rear side 15b of the cage-side flange 15, an axial web 30 is provided as a circumferential contact collar, on which the radially outer sealing lip 13a rests on the outer circumference or on which the sealing element 13 is supported in the radial direction R.

In the area of the connector plug 11, a Fe derelement 31 is provided with a central locking dome 32 for further locking of the loudspeaker 4 with the support element 2 on the flange 15 on the back flange (FIG. 8).

On the flange 15 of the loudspeaker frame 10 on the opening edge 16 of the receiving opening 9 facing the rear flange 15b are in the circumferential direction of the basket-side flange 15 running, in particular arcuate, ramps (Launch ramps) 33 provided. The ramps 33 extend only over a limited arc or arc section, preferably with a center point angle of the radii of the arc of between 10° and 30°, suitably between 15° and 20°.

The ramps 33 are used to generate a contact pressure on the sealing element 13 during the rotary movement in the course of producing the bayonet connection between the loudspeaker 4 or its loudspeaker basket 10 and the carrier element 2. The respective ramp 33 is in the area of the contact interface 14 between the carrier-side receiving opening 9 and the sealing element 13 and is thus located radially inward of the sealing element 13. This ensures the function of the ramp 33 and also reliably provides the sealing function of the sealing element. In addition, the mounting of the loudspeaker 4 on the carrier element 2 is simplified by means of the ramps 33 .

During the rotary movement of the loudspeaker basket 10 in relation to the carrier element 2, in particular during the course of the manufacture of the bayonet lock, the ramps 33 in the area of the mechanical contact or connection interface 14 provide a starting aid by initially reducing the sealing pressure at the start of assembly and in the course of the further rotary movement during the joining process, the specified contact pressure is generated on the sealing element 13 .

With increasing rotational movement of the loudspeaker 4 or its basket 10, the carrier-side joining contours 26 reliably extend along the insertion or inlet ramps 33 under or behind the basket-side joining elements 25 until the bayonet catch is produced, including the locking or locking by means of the snap-in connection between the carrier-side Latching elements or latching pins 29 and the basket-side latching depressions 27. For this purpose, the respective ramp 33 is arranged in front of the basket-side joining element 25 in such a way that during the rotational movement of the loudspeaker basket 10 in the area of the mechanical system or connection interface there is initially a reduced sealing pressure and during the course of the further rotational movement of the Loudspeaker 4 or the loudspeaker frame 10 an increasing contact pressure on the sealing element 13 is generated. To avoid water accumulating in the wet room on the loudspeaker 4, a suitable water drain W is provided, avoiding the formation of a trough in which water could collect. The water drain W is suitably provided at a lowest point P, which means at a lower point in the Z-direction of the vehicle of the contact interface 14 of the assembly arrangement between the loudspeaker frame 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 with 24 ′, which extends over a circle segment and in the radial direction slightly into the basket-side contact interface 14 .

In the area of these basket openings or basket-side recesses 24', the radial width of the flange rear side 15b is smaller than the radial width of the flange rear side 15b extending in the circumferential direction outside of this area. The basket-side flange 15 is at this point in the region of the lowest point P directly, this means edge and stepless, in the basket-side recess 24 'over (Fig. 4).

Figures 7 and 8 show the support element 2 in different perspective views, with Fig. 7 showing the support element 2 from the rear facing away from the loudspeaker 4 (wet room side) and Fig. 8 showing the support element 2 from the loudspeaker 4-facing system or mounting side (drying room side) shows. In Fig. 7, the support-side locking pins 29 can be seen on the running as Radialla's joining contours 26 of the support element 2.

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

FIGS. 10 and 11 show perspective views of the rear (wet room side) or the front (dry room side) of the mounting arrangement of the loudspeaker 4 or its basket 10 on or on the support element 2 with the bayonet lock made, including the snap-in connection between the snap-in elements 27 and 29 on the basket and carrier side.

In FIGS. 7 and 8, cutouts 34 in the form of arcs of a circle can be seen between the joining contours 26 on the carrier side. The joining elements 25 on the basket side engage in these cutouts 34 on the carrier side during the insertion movement in the course of the loosening position of the bayonet catch. The carrier-side cutouts 34 provide different circular arc lengths by further radial struts or tabs 35, which protrude into the carrier-side receiving opening 9 within certain cutouts 34 and are formed on the peripheral wall 16, form different sized circular segments of the cutouts 34. As a result, there is only a single intended or possible insertion position of the respective basket-side joining element 25 of the loudspeaker basket 10 into these carrier-side cutouts or recesses 34 for the fixing position of the bayonet catch during the plugging movement.

In FIG. 8 a bead-like latching depression 37 with a (central) latching groove 38 can be seen in the area of the molded part 21 of the carrier element 2 . When the bayonet catch is in the released position, the carrier-side latching recess 37 accommodates the basket-side spring element 31, with the latching dome 32 of the basket-side spring element 31 latching into the latching groove 38 of the carrier-side latching recess 37 for an additional latching connection of the loudspeaker 4 or its basket 10.

At the lowest point P, which means at a location or position of the carrier element 2 provided as far down as possible, a circular segment-like recess 36 for the water outlet W is provided at the opening edge 16 of the receiving opening 9 of the carrier side. This carrier-side recess 36 is aligned with the basket-side recess 24 ′, which also extends at least slightly radially into the contact interface 14 over a segment of a circle and in a suitable manner. In this area of the carrier-side recess 36, the radial width of the contact interface 14 is smaller than the radial width of the annular contact interface 14 extending in the circumferential direction outside of this area. In other words, in this area of the carrier-side recess 36, the radial width of the peripheral edge 16 the carrier-side receiving opening 9 smaller than the radial width of the (annular) section of the carrier-side peripheral edge 16 of the receiving opening 9 that extends outside of this area.

As can be seen from FIGS. 10 and 11, when the assembly arrangement is produced, the radially inner peripheral side or surface of the sealing element 13 or its radially inner sealing lip 13b is aligned with the recess 36 on the carrier side and with the recess 24' on the basket side in the region of the lowest point P for the provision of the water drainage W. A radially inner circular segment-like peripheral area of the sealing element 13 arranged on the basket-side flange 14 in the area of the basket-side recess 24' transitions into the carrier-side recess 36 as seamlessly or without edges as possible and/or over a large area .

12 shows a sectional view of the joining area with the latching connection between one of the joining elements 25 on the basket side and the corresponding joining contour 26 on the carrier side, as well as the contact of the sealing element 13 on the mechanical contact interface 14 between the mounted loudspeaker 4 or its basket 10 and the carrier element 2 with manufactured bayonet lock.

Due to the design of the opening edge 16 of the carrier-side receiving opening 9 and the basket-side flange 15 on its flange rear side 15b, in particular by means of the axial centering pins 39 provided there, which can be seen comparatively clearly in Figures 5 and 9, during the production of the bayonet lock, in particular during the plug-in 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.

The radially inner sealing lip 13b acts as a radial sealing element (in radial seal R) and also as a centering element when the loudspeaker 4 or its loudspeaker basket 10 is (plugged) installed in the receiving opening 9 of the carrier element 2, particularly in the area of the contact interface 14. The radially outer, axially protruding 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 carrier element 2 in the area of the contact interface 14. In summary, the invention relates to a mounting arrangement of a loudspeaker 4, in particular 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 and a sealing element 13 in the area of a mechanical interface 14 are provided between the loudspeaker basket 10 and the support element 2 . In the course of assembly, the speaker basket 10 passes through the carrier-side receiving opening 14, and the basket-side flange 15 is located on the carrier element 2 with the interposition of the sealing element 13. To produce a bayonet closure or a plug-and-turn joint connection in or within the assembly arrangement, the loudspeaker basket 10 has a number of joining elements 25, which are arranged in particular on basket struts 23 of the loudspeaker basket 10 and which correspond to joining contours 26 of the carrier element 2.

Additionally or alternatively, on the flange 15 on the cage side, on the flange side 15b facing the contact interface 14, there is at least one preferably arcuate ramp 33 running in particular in the circumferential direction of the flange 15 on the cage side, for generating a contact pressure on the sealing element 13.

Furthermore, in addition or as an alternative, in particular at a lowest point P of the system interface 14, between the loudspeaker frame 10 and the system interface point 14 of the carrier-side receiving opening 9, a water drain W, in particular without a trough, is provided.

Furthermore, in addition or as an alternative, a plug receptacle or bushing 22 is provided in or on a molded part 21 of the carrier element 2 in such a way that - preferably according to the Poka-Yoke principle - only then is a plug-in contact made with an external mating connector 11a with a basket or speaker side At connector 11 is made possible when the speaker 4 or its basket 10 tion in the carrier-side receiving opening 9 in an intended target posi or target position (target end position) sits. The claimed invention is not limited to the embodiments described above. Rather, other variants of the invention can also be derived from this by the person skilled in the art within the scope of the disclosed claims without departing from the subject matter of the claimed invention. In particular, all of the individual features described in connection with the various exemplary embodiments can also be combined in other ways within the scope of the disclosed claims without departing from the subject matter of the claimed invention.
