Abstract

An interior component of a vehicle comprises a carrier having a front face directed toward a passenger compartment of the vehicle and an opposite rear face; a speaker including an at least partially transparent diaphragm and a transducer coupled to the diaphragm. Movement of the transducer causes vibration of the diaphragm to generate sound by vibration of the diaphragm, the diaphragm having a front face directed towards the passenger compartment and an opposite rear face. The carrier provides a support along at least part of the periphery of the diaphragm where the diaphragm is attached to the carrier where the front face and the rear face of the diaphragm are free of the carrier across a part of the diaphragm surface so that the diaphragm is suspended in the carrier of the interior component.

First claim

The invention claimed is:

1. An interior component of a vehicle, the interior component comprising:
a carrier having a front face directed toward a passenger compartment of the vehicle and an opposite rear face;
a speaker including an at least partially transparent diaphragm and a transducer coupled to the diaphragm, wherein movement of the transducer causes vibration of the diaphragm to generate sound by vibration of the diaphragm, the diaphragm having a front face directed towards the passenger compartment and an opposite rear face;
wherein the carrier provides a support along at least part of a periphery of the diaphragm where the diaphragm is attached to the carrier wherein the front face and the rear face of the diaphragm are free of the carrier across a part of a diaphragm surface so that the diaphragm is suspended in the carrier of the interior component, and
wherein the transparent diaphragm comprises two sheets of annealed or tempered glass and a polymer interlayer between the glass sheets.

2. The interior component of claim 1 , wherein the diaphragm is suspended in the interior component by providing in the carrier open spaces at the front face and the rear face of the diaphragm.

3. The interior component of claim 1 , wherein the carrier provides support along an entire periphery of the diaphragm.

4. The interior component of claim 1 , wherein the transducer is coupled to the diaphragm at a surface portion of the diaphragm where the carrier covers the front face of the diaphragm.

5. The interior component of claim 1 , further including a light source provided at the carrier, behind the carrier, at the diaphragm or behind the diaphragm and configured to transmit light to the front face of the diaphragm.

6. The interior component of claim 1 , further including a surface opposite to the rear face of the diaphragm wherein a gap is formed between the rear face of the diaphragm and the surface opposite to the rear face.

7. The interior component of claim 6 , wherein the gap has a width of at least 50 mm.

8. The interior component of claim 1 , wherein at least one of the surface of the diaphragm and a surface opposite to the rear face of the diaphragm is structured to manipulate sound waves emitted from the diaphragm towards surface.

9. The interior component of claim 8 , wherein the at least one surface is structured to selectively resonate, reflect, divert, scatter, direct and/or focus sound waves.

10. The interior component of claim 8 , wherein the at least one surface is structured as a sound board.

11. The interior component of claim 8 , wherein the at least one surface is structured to include at least one convex or concave dome shape.

12. The interior component of claim 8 , wherein the at least one surface is structured to include a plurality of convex and/or concave dome shapes arranged in a pattern.

13. The interior component of claim 8 , wherein the at least one surface is structured to include a plurality of surface portions having different inclination angles relative to a main plane of the diaphragm.

14. The interior component of claim 1 , wherein the diaphragm is arranged and/or shaped to generate sound waves having a center of propagation directed at an area within a vehicle cabin which is located in front of and adjacent to a passenger head rest.

15. The interior component of claim 1 , wherein the diaphragm is 2.5D or 3D shaped.

16. The interior component of claim 1 , wherein the diaphragm has an overall thickness of between 1 mm and 2 mm.

17. The interior component of claim 1 , wherein the carrier is a carrier of a pocket of a door lining, the carrier including a cut out forming a frame for supporting the diaphragm wherein, when mounted, the front face and the rear face of the diaphragm are accessible to a passenger of the vehicle.

18. The interior component of claim 1 , wherein the carrier is a carrier of a door lining or a central console or a floor console, the carrier defining a sound box having an opening at the front face of the carrier, wherein a transducer is arranged at a rear side of the sound box to emit sound through the sound box to the front of the carrier.

19. The interior component of claim 18 , wherein, when mounted, the opening is located in an area at or below a seat level of a passenger seat in a vehicle cabin.

20. The interior component of claim 1 , wherein the diaphragm is part of or covers a digital side view mirror or a digital rearview mirror.

21. The interior component of claim 1 , wherein the diaphragm is part of or covers a touch screen.

22. The interior component of claim 1 , wherein the diaphragm is part of or covers a decorative appliqué.

23. The interior component of claim 1 , wherein the polymer interlaver is a clear damping layer comprising PVB.

24. The interior component of claim 1 , wherein the transducer is a piezoelectric transducer arranged at a flat surface portion of the diaphragm.

25. The interior component of claim 1 , further including a pattern on the front face of the diaphragm.

26. The interior component of claim 1 , wherein an overall thickness of the diaphragm is between 1 and 2 mm and the two glass sheets are tempered.
