Embodiment Construction

[0038] The invention is now described in more detail in a non-limiting manner in the following description.

[0039] The invention relates to a roof of a vehicle comprising a wall panel and at least one audio device (3) selected from speakers and actuators. When the at least one audio device is the actuator (or actuators), which is located on the wall, the wall can be brought into vibration.

[0040] "Audio device" refers to a device capable of producing sound, such as music or speech. "Audio system" means a system capable of producing sound.

[0041] "Surface" means any surface that may form part of the roof of a vehicle.

[0042] Preferably, the wall panels are glazing (the roof comprising glass portions, or glazing, referred to herein as a glass roof). Alternatively or additionally, it may be another surface, such as a metal siding, such as steel plate.

[0043] "Glass" means any element having a sheet-like shape and comprising at least one sheet (or ply) of glass. Gla...

Abstract

The invention relates to a roof (1) of a vehicle, in particular a motor vehicle. The roof comprises a wall panel, and at least one audio device (3) selected from the group consisting of loudspeakers and actuators, and when the at least one audio device (3) is an actuator, the audio device (3) is located on the wall panel, and the wall panel is able to enter a vibrating state. The invention also relates to the vehicle comprising such roof.

Description

technical field [0001] The invention relates to a vehicle roof comprising a wall panel and one or more speakers and / or actuators and a vehicle comprising such a roof. Background technique [0002] Due to the development of infotainment, the audio system is now an important part of the vehicle. [0003] In most vehicles, the speakers for these audio systems are found in the vehicle's doors and dashboard. However, this arrangement of speakers has several disadvantages. In fact, due to the mobility of the door, the speaker must be integrated into the door with a rigid structure to reduce vibration and stabilize the speaker. These structures take up a lot of space in the door and increase the weight of the door. Furthermore, traditional front speakers are relatively far from the passenger's ears, resulting in a loss of high fidelity performance for the passenger. In particular, due to obstacles in the sound path, such as seats and other passengers, high frequencies are often...
