Description

[Detailed description of the invention] This invention is a speaker that is attached to the door of a car, etc.
The present invention relates to an improvement in a waterproof cover for a so-called door-mounted speaker, which covers the upper surface of the speaker and protects the speaker from rainwater entering the door.

A conventional waterproof cover of this type generally has a structure shown in FIG. In FIG. 1, reference numeral 1 denotes an inner lining of an automobile door, 2 a speaker having a flange portion 2a attached from the outside to an opening 1a of the inner lining 1, and 3 a space between the flange portion 2a of the speaker 2 and the inner lining 1. One end 3a is attached, and the other end 3b is the magnetic circuit 2b of the speaker 2.
The speaker 2 is located at the rear of the top panel 3c.
This is a synthetic resin waterproof cover that protects the door from rainwater that enters the door.

By the way, this conventional waterproof cover 3 is made by simply bending both ends of a flat plate made of synthetic resin, so it is not stretchable, and it is necessary to prepare several types due to differences in the overall height of the speaker. , small lots and a wide variety of products were produced, leading to high costs and troublesome product management. In addition, when embedded in a door, if there is an obstacle near the speaker inside the door, since the top plate part 3c of the waterproof cover 3 is a flat plate, it is difficult to deform and cannot be installed.

This idea was created by focusing on the points mentioned above.
The purpose is to provide a waterproof cover for a door-mounted speaker that can be used regardless of the size of the speaker and can be freely deformed, so that it can be used regardless of installation conditions.

Next, an embodiment of the present invention will be described with reference to FIGS. 2a, b, and c. Note that a to c show the deformed states of the waterproof cover when the sizes of the speakers are different. Further, in the drawings, the same reference numerals as in FIG. 1 indicate the same members, and explanations thereof will be omitted.

The waterproof cover 3 according to the present invention has a top plate portion 3c shaped like a bellows, and a magnetic plate 4 is attached to an end portion 3b corresponding to the magnetic circuit 2b.

To attach the waterproof cover 3, when screwing the flange portion 2a of the speaker 2 to the opening 1a of the lining 1, one end 3a of the waterproof cover 3 is sandwiched between the flange portion 2a and the lining 1. .
During this installation, when the speaker 2 is pushed into the door with the magnetic plate 4 attached to the other end 3b of the waterproof cover 3 adsorbed to the magnetic circuit 2a, the bellows of the top plate 3c will extend and the speaker 2 will It will cover the top. Further, even if an obstacle exists on the top plate portion 3c during this installation, since the top plate portion 3c is bellows, it can be deformed and attached along the obstacle. Furthermore, since the other end 3b of the waterproof cover 3 is attracted to the magnetic circuit 2a of the speaker 2, the waterproof cover 3 can be securely fixed without play, and noise such as chatter can be prevented.

Note that Fig. 2 a shows the case of a standard-sized speaker, and the top plate part 3c of the waterproof cover 3 is longer than that of the thin-sized speaker shown in b, and is smaller than that of the deep-sized speaker shown in c. .

As mentioned above, the present invention has a bellows-shaped top plate that covers the top of the speaker, so one type of waterproof cover can be used regardless of the overall height of the speaker, which reduces costs and simplifies management. Furthermore, even if there are some obstacles, the top plate part can be easily deformed so that it can be installed, and therefore it can be used regardless of the installation conditions.

In addition, since the extension at the other end of the top plate is fixed to the back of the magnetic circuit by adsorption of a magnetic plate, both ends of the top plate are securely fixed, and in order to save materials, it is not possible to support the top plate on a cantilever. Even if you make the top plate thin,
The waterproof cover can be securely fixed without any play, and noises such as rattling can be prevented.

Furthermore, since the magnetic plate is fixed to the back surface of the magnetic circuit, the thickness of the yoke portion of the magnetic circuit increases accordingly, which is advantageous in terms of the characteristics of the magnetic circuit.
