Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device that utilizes the cabinet section of a vehicle-mounted speaker unit and can illuminate display information contents when necessary, such as at night or during braking.

In recent years, as in-vehicle speaker units, in addition to the general embedded type, so-called stationary box speakers 1, 1, which are installed on the rear shelf of the vehicle interior as shown in Fig. 1, have been widely used. It's getting old. This kind of box type speaker unit 1, 1 has a large cabinet part due to its structure, and especially in the direction opposite to the sound emission direction, that is, the part visible from the following vehicle (part A in Fig. 1), the cabinet part is large. The area of this section is the largest.

Conventionally, the back of the cabinet of this type of speaker unit 1, 1 was designed to improve the overall design of the product.
The model name of the product or the brand name of the manufacturer was merely printed and displayed in section A of FIG.

However, with such a simple printed display, the above-mentioned advertising effect cannot be expected at all in dark surroundings such as at night, and from the viewpoint of the design effect of the product, the cabinet The reality was that the large area at the back of the building was not fully utilized.

The present invention was developed in view of these circumstances, and by attaching a display member with an extremely simple structure to the back of the cabinet of an in-vehicle speaker unit, it enhances the design effect of the speaker unit as a product. Furthermore, it is an object of the present invention to provide a display device that can appropriately display information even at night or when braking, thereby increasing advertising effectiveness.

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

FIG. 2 shows an embodiment of the display device according to the present invention. In the figure, the reference numeral 10 is a cabinet section of an on-vehicle speaker unit, and a protective net 11 is provided on the front surface of the cabinet section. is,
Further, a signal lead wire 12 for an internal speaker (not shown) is drawn out from the lower side of the back surface.

A plate-shaped display member 20, which characterizes the present invention, is attached above the back surface of the cabinet section 10 of such a speaker unit.

To explain this in detail using FIG. 3, the entire display member 20 is formed into a plate shape from a transparent synthetic resin material such as acrylic, and in the center of its surface (section C in FIG. 3), Display information 21 constituting a single information display section as shown in FIG. 2 is printed out. Display members 2 other than this display information 21
The entire surface of 0 is opaquely treated by printing or painting. This is to prevent light from leaking from unnecessary parts and impairing the illumination effect when displaying the display information 21 at night, and to increase the efficiency of illumination.

Further, two insertion holes 22 and 23 are bored in parallel on one side of the display member 20 toward the other side, and lamps 24 and 2 are provided in these insertion holes 22 and 23.
4 are inserted as light sources. A red rubber cap 25 and a green rubber cap 26 are respectively placed over the light-emitting portions at the tips of the lamps 24, 24.

In this case, the negative electrode sides of these two lamps 24, 24 are connected in common, and the positive electrode sides are electrically connected to the power supply section of the rear lighting device of the car, which is indicated by reference numeral B in FIG. . Here, the positive lead wire 27a of the lamp 24 covered with the green rubber cap 26 is connected to the power supply section for the night light, which is always energized when the night light switch of the car is turned on. The wire 27b is connected to the brake light power supply unit that is energized when the car's brakes are applied, and also to the two lamps 24, 24.
The common negative lead wires 27c are each electrically connected to the vehicle body as a ground.

Note that reference numeral 28 in FIG.
0 is this screw mounting hole 2 as shown in Fig. 2.
It is attached and fixed to the back surface of the cabinet section 10 with four screws 29 via the screw 8.

According to such a configuration, the contents of the display information 21 are clearly displayed using natural light during daytime driving as before, and when the brakes are applied, the display information 21 is also displayed lit in red at the same time as the brake lights are lit.

On the other hand, when driving at night, the display information 21 is displayed in green by turning on the night light switch of the car. In this case, when the brakes are applied, the display may be switched to red and displayed as in the case of daytime driving.

In addition, in the above-mentioned embodiment, a case was explained in which screws of 29 yen were used to attach the display member 20 to the speaker unit, but the present invention is not limited to this, and the display member 20 is attached to the speaker cabinet.
It is easily understood that the screws may be integrally formed by embedding 0 therein, and double-sided adhesive tape or the like may be used instead of the screws.

In addition, two lamps 24, 24 covered with seat-colored and green rubber caps 25, 26 are used as light sources for illuminating the display, but the number of lamps can be increased or decreased, the color can be changed, or It goes without saying that other elements such as a light emitting diode may be used as the light source in addition to the lamp, and this can further enhance the design effect.

As explained above, according to the present invention, two light sources that illuminate a single display board are provided, and when the car is braking, a second light source of a color different from the color of the first light source that illuminates each display board is used. The color of the same display board is changed from the color of the first light source to the color of the second light source, or to a mixture of the color of the first light source and the color of the second light source. Since the vehicle interior is changed, the space inside the vehicle can be used effectively and an excellent advertising effect can be achieved by giving a psychological surprise to rear drivers.
