Description

[Detailed description of the invention] This invention relates to the improvement of the frame of a door-mounted car speaker device, and the purpose is to make the frame itself drip-proof by devising the shape of the frame. .

As shown in Fig. 1, a door-mounted car speaker has a radiation aperture surface arranged on the lining plate 2 of the car door, which is made up of an outer panel 1 and an lining plate 2, and the rear of the speaker is connected to the inner lining plate 2. It is fixed so as to be housed in a space 3 formed by the plate 2 and the outer plate 1.

A window glass 4 is attached so as to slide vertically between the inner panel 2 and the outer panel 1.

In such a configuration, rainwater or moisture adhering to the window glass 4 becomes water droplets and flows into the space 3.
into the frame opening window 5 and dripped onto the speaker.
This type of speaker needs to have a drip-proof function in order to penetrate into the speaker frame.

For this reason, in the past, a drip-proof cover 6 separate from the speaker was disposed to cover the upper part of the speaker, but this increases the number of parts and requires more man-hours for installation, making it impractical.

Furthermore, if a so-called closed type frame in which the frame is not provided with an opening window is used, the frame itself can be provided with a drip-proofing effect, but on the other hand, the buffering effect is drastically reduced and the low frequency reproducing power is significantly degraded.

In order to solve these drawbacks of the conventional example, this invention minimizes the deterioration of the buff-full effect by providing an opening window in a part of the speaker frame and forming a gutter-like bent part around the periphery of the opening window. The embodiment shown in FIGS. 2 and 3 will be described in more detail below.

In FIG. 2, reference numeral 21 denotes a speaker frame, and an opening window 2 is provided only in the lower part of the frame 21 when it is attached to the lining plate 2.
1a is bored, and a gutter-like bent portion 21b is formed by bending the peripheral edge of the opening window 21a.

The trough-like bent portion 21b can be easily formed when the frame is formed.

The speaker having such a frame 21 is attached to the door lining plate 2 so that the opening window 21a is positioned downward. (FIG. 3) Since the water droplets dripping onto the frame 21 flow along the gutter-like bent portion and fall downward, the water droplets do not enter into the frame 21 through the opening window 21a.

Further, by providing the opening window 21a, a buffer effect can be obtained, and deterioration of the low frequency reproduction ability can be suppressed to a minimum.

Furthermore, the frame 21 is formed by the gutter-like bent portion 21b.
It has extremely excellent practical effects such as increased strength.
