Problems solved by technology

[0003] However, this area of ​​the cover can be deformed, for example in the event of a hard impact, which is attributed to the impact itself, but also to the triggering of the ignition that activates the airbag
This can be problematic in keeping the grille in place, the grille covering the speakers could come off the lid and be thrown into the passenger compartment, potentially jeopardizing the safety of the occupants

Embodiment Construction

[0019] The first three figures - namely FIGS. 1 , 2 and 3 - show the individual grid 10 in different views prior to installation on the dashboard cover 20 . FIG. 4 shows the grille 10 in place in the dashboard cover 20 and covering the speakers 30 in a cross-sectional view.

[0020] Loudspeaker 30 includes a housing 31 that generally supports a membrane 32 , an electromagnet 33 and a connector 34 . The housing 31 itself is mounted in a recess 23 located in the lower part of the cavity 21 of the cover 20 between the outer skin of the cover 20 and the structural wall. The housing includes not shown means for fastening to the dashboard cover 20 .

[0021] The speaker 30 should be able to be installed in the upper part of the cover 20 , that is, in the upper part of the cavity 21 . The cavity 21 is substantially cylindrical, and its diameter is larger than that of the speaker 30 .

[0022] According to the invention, the grid 10 comprises main fixing means for fixing the grid 1...

Abstract

The invention relates to a subassembly for securing a grid (10) of a loudspeaker (30) for the interior fittings of a vehicle, the subassembly comprising a wall (25) of a cover (20) defining a housing (219 for a loudspeaker (30) and a grid (10) covering the housing (21) comprising main elastic fixation means (11) that co-operate with the wall (25) of the cover (20), characterised in that the main elastic fixation means (11) co-operate with a first portion of the hosing (21) and in that the subassembly includes secondary retaining means comprising in a lower portion of the housing (21) separatefrom the first portion, at least one female fixation member (24) at least one male fixation member (13) is inserted.

Description

technical field [0001] The invention relates to a subassembly of a grill for securing loudspeakers in the interior of a vehicle, the subassembly comprising walls of a cover delimiting a speaker cavity and a grill covering the cavity, the grill comprising elastic main elements cooperating with the walls of the cover Fixtures. Background technique [0002] Typically, motor vehicles are equipped with a dashboard having a lid visible to passengers. In some vehicles, a small diameter, eg 30mm diameter speaker, commonly referred to as a tweeter, allows high frequencies, the "treble" of the vehicle's audio system, to be emitted. The chosen placement of these small speakers in the lid and adjacent to the windshield, near the side pillars, enables near-ideal propagation of the "treble notes" in the upper part of the passenger compartment by reflecting off the windshield. [0003] However, this area of ​​the cover can become deformed, for example in the event of a hard impact, which...
