Embodiment Construction

[0030] see figure 1 , figure 1 It is a schematic diagram of the first embodiment of a vehicle sunroof lighting device with an electret horn according to the present invention. The figure shows a vehicle sunroof module 2 embedded in a roof panel 9 . In this embodiment, the vehicle sunroof module 2 includes a glass 20 and an electric opening and closing module 201 , and the electric opening and closing module 201 is used to open or close the glass 20 . That is, the vehicle sunroof module 2 of this embodiment is a conventional glass sunroof module.

[0031] In addition, an electret horn 3 and an electroluminescent plate 210 are also shown in the figure. The electret horn 3 is a light-transmitting electret horn 3 and is directly attached to the glass 20 . In addition, the electroluminescent plate 210 of the present embodiment is a frame-shaped electroluminescent plate 210 assembled on the outer periphery of the glass 20 to increase the lighting effect. Of course, the electrol...

Abstract

The invention relates to a vehicle skylight illumination device with an electret horn. The device comprises a vehicle skylight module, the electret horn and a controller, wherein the vehicle skylight module includes a simulation skylight device and a fixed frame, the simulation skylight device includes at least an electro-excitation optical plate electrically coupled to the controller, the fixed frame includes a clamping groove and a fixed platform, the electret horn is housed in the clamping groove, the at least an electro-excitation optical plate is fixed on the fixed platform. Therefore, by integrating the vehicle skylight module with the electret horn, the device can provide illumination and acousto-optic effects such as music or audio playback and the like for a vehicle room, occupies small space, has light weight, and can greatly increase the using space of the vehicle room.

Description

technical field [0001] The invention relates to a vehicle sunroof lighting device with an electret horn, in particular to a vehicle sunroof lighting device with an electret horn suitable for the interior of a vehicle compartment. Background technique [0002] Electret horns, commonly known as paper horns, were first developed by the Institute of Industrial Technology. In addition, the membrane layer for fixing the electrode plate is provided with a plurality of arrayed hollow convex spacers and ventilation holes, and the surface of the membrane layer for fixing the electrode plate is provided with an electrode film. However, the hollow convex spacers of the fixed electrode plate are attached to the diaphragm. Accordingly, when a low voltage is applied to the electrode film on the fixed electrode plate and the conductive film on the vibrating film, it is sufficient to form an electric field to push the vibrating film to emit sound. [0003] Furthermore, the electret horn no...
