Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an automobile door having a speaker attached thereto, and relates to a door water-proof structure that prevents water from entering the speaker attachment portion.

[Technical background of the invention and its problems]

A conventional door waterproof film structure of this type is shown in FIG. In Fig. 3, 1 is an outer panel, 2 is an inner panel,
Reference numeral 3 denotes a trim attached to the inner panel 2, and these outer panel, inner panel, and trim are components of an automobile door. A speaker mounting hole 2a is formed in the inner panel 2, and a speaker storage pocket 4 is fitted into the speaker mounting hole 2a. A speaker 5 is attached to the speaker storage pocket 4 from the trim 3 side. Furthermore, a waterproof film 6 is provided between the inner panel 2 and the trim 3. This waterproof film 6 has an opening at a position corresponding to the speaker mounting hole 2a, and the periphery of the opening is fixed to the flange portion of the speaker storage pocket 4 via a packing or the like.

Therefore, even if water (such as rainwater) enters the door through the gap in the door window, the water will fall through the waterproof film 6 and the speaker storage pocket 4 as shown by the broken line in the figure.
It does not enter the trim 3 side or the speaker 5 side.

However, in such a door waterproof film structure, the back side of the speaker 5 is sealed with the speaker storage pocket 4 and there is no ventilation, and the sealed space is narrow, so the speaker 5
The drawback was that the sound quality was poor.

Furthermore, as shown in FIG. 4, there is a device in which the speaker storage pocket 4 is removed and a waterproof film 7 is provided in its place. The upper end of the waterproof film 7 is attached tightly above the opening of the waterproof film 6, and the lower end of the waterproof film 7 is hung down so as to cover the drive section of the speaker 5. Water that enters through gaps in door windows, etc. is removed by the waterproof films 6 and 7 as shown by the broken lines in the figure, preventing water from entering the trim 3 side and the speaker 5 side, and ventilating the back side of the speaker 5. It is made to have a sexual nature.

However, in this case, the waterproof film 7 comes into close contact with the driving part of the speaker 5 as shown in the figure, and due to this close contact, sufficient air permeability cannot be ensured, resulting in poor sound quality.

[Purpose of invention]

This idea was created in view of the above circumstances, and its purpose is to create an excellent product that not only prevents water from entering the trim side and speaker side, but also improves the sound quality of the speaker. The object of the present invention is to provide a waterproof door structure.

[Summary of the idea]

This idea provides a first waterproof film having an opening at a position corresponding to the speaker mounting hole of the inner panel between the inner panel and the trim, and the upper part of the speaker storage pocket that is fitted into the door mounting hole. At the same time, the first
The upper end of a second waterproof film is tightly attached above the opening of the waterproof film, and the lower end of the second waterproof film is hung down to cover the cutout of the speaker storage pocket. It is.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. However, in the drawings, the same parts as in FIGS. 3 and 4 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

First, the water-proof film 6 will be referred to as a first water-proof film, and the water-proof film 7 will be referred to as a second water-proof film.

Therefore, as shown in Figures 1 and 2,
The upper part of the speaker storage pocket 4, for example, approximately the upper half, is cut off, and the speaker storage pocket 4 is fitted into the speaker mounting hole 2a of the inner panel 2. In this case, the speaker storage pocket 4 is cut out so that the upper edge of the portion remaining after the cutout is directed downward and forms a curved shape. A second waterproof film is provided above the opening of the first waterproof film 6 provided between the inner panel 2 and the trim 3.
The upper end of the second waterproof film 7 is attached tightly, and the lower end of the second waterproof film 7 is hung down so as to cover the cutout of the speaker storage pocket 4.

Therefore, with such a configuration, water that enters from the gap in the door window or the like falls through the waterproof films 6 and 7 as shown by the broken line in the figure, and enters the trim 3 side and the speaker 5 side. Never. Furthermore, since the second waterproof film 7 comes into contact with the upper edge of the speaker storage pocket 4, which has approximately the upper half cut off, it does not come into close contact with the drive section of the speaker 5. Moreover, the speaker storage pocket 4 which is the contact part
Since the upper edge has a curved shape, a gap is created between it and the second waterproof film 7, and a ventilation path is secured in the vertical and horizontal directions on the back side of the speaker 5, as shown by the arrows in the figure. Ru. In other words, the sound quality of the speaker 5 can be improved. Furthermore, since such waterproofness and breathability are ensured by three parts: the speaker storage pocket 4, the first waterproof film 6, and the second waterproof film 7, the structure is simple.
Easy installation is possible without enlarging the speaker mounting hole 2a.

In addition, in the above embodiment, the speaker storage pocket 4
Although the portion to be removed is approximately the upper half, the size of the portion to be removed may be appropriately determined depending on the size of the speaker storage pocket 4, the thickness of the driving portion of the speaker 5, etc. In addition, this invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without changing the gist.

[Effect of idea]

As described above, according to the present invention, it is possible to provide an excellent door waterproof structure that can not only prevent water from entering the trim side and the speaker side, but also improve the sound quality of the speaker.
