Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a speaker box that is used in various types of audio equipment, and is especially suitable for in-vehicle audio equipment.

(Prior Art) Conventional speaker boxes of this type have mainly had a closed structure as shown in FIGS. 3 and 4. That is, a baffle plate 2 is fixed to the cabinet body 1 with a sealing gasket 3 interposed therebetween by screws. A speaker 5 is attached to the baffle plate 2, and a protective net 4 for protecting the speaker is attached to the front surface of the speaker 5.

The cabinet main body 1 and the bulky plate 2 are joined together on the same plane, and a foamed resin sheet, a molded product of rubber or resin, or the like is sandwiched between the joined surfaces as a sealing packing 3.

(Problem that the invention aims to solve) If the joint surfaces are on the same plane (two-dimensional) as in this conventional box, the sealed structure is simple and there is no problem, but the shape of the box is complex and the joint surfaces are When it is impossible to make them on the same plane, that is, when the joint surface between the cabinet body and the full board has a three-dimensional shape, the problem with conventional foam resin sheets is that the work of pasting them is extremely time-consuming. Moreover, since the molded product has a three-dimensional shape, there are problems such as difficulty in maintaining the shape and making it difficult to fit into the cabinet body.

Therefore, the present invention provides a box sealing structure and sealing packing material that can perform its function without any trouble even on complex three-dimensional joint surfaces, does not cause a decrease in workability, and has an excellent appearance.

(Means and effects for solving the problem) In order to solve this problem, the present invention provides a step portion that slightly protrudes from the outer wall side around the entire circumference on either the cabinet body or the joint surface of the buttful plate. At the same time, the stepped portion is provided with a groove all around the circumference, and the other joint surface is provided with a stepped portion that fits into the stepped portion. A gel-like filler such as silicone is applied and filled into the groove, and this is sandwiched between the cabinet body and the baffle plate as a sealing material and fixed. Since the gel filler is applied using a computer-controlled coating machine, work efficiency is improved and it is easy to apply to three-dimensionally shaped joint surfaces.

(Embodiment) Hereinafter, a sealed structure of a speaker box in an embodiment of the present invention will be described.

FIG. 1 shows a cross section of the cabinet body 11.
A buttful plate 12 is fixed to the housing with screws, sandwiching a sealing gasket 13 therebetween. A speaker 5 is attached to the baffle plate 12, and a protective net 4 is attached to the front surface of the speaker 5.

The main body 11 of the cabinet is provided with a step portion around the entire circumference of which the outer wall side slightly protrudes, and a groove 14 is provided in the step portion over the entire circumference.
The groove 14 is filled with a gel filler (sealing packing 13) such as silicone.
On the other hand, the cabinet body 1 is mounted on the buffer board 12.
A stepped portion that fits into the stepped portion of 1 is provided,
The cabinet body 11 and the baffle plate 12 are joined with the sealing gasket 13 sandwiched therebetween.

In this embodiment configured as described above, even if the bonding surfaces of the cabinet body 11 and the baffle plate 12 are not on the same plane and have a three-dimensional shape, the gel filler 13 is coated using a computer-controlled coating machine.
can be applied quickly and reliably, improving work efficiency. Further, by providing a stepped portion on the joint surface, the sandwiched filler does not protrude to the outside of the box, and the inside of the box can be reliably sealed without impairing the appearance.

Note that a step portion having a groove may be provided on the buttful side.

(Effects of the Invention) As described above, the present invention allows work to be easily performed even on the joint surface of a complex three-dimensional box by using a gel-like filler in the sealing packing material. There is no need for a mold for the endless packing as in the past, resulting in significant improvements in cost reduction and workability. Furthermore, since the packing is not visible from the outside of the box, it has great practical effects, such as improved aesthetics.
