Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a shock absorbing mechanism for a stationary vehicle-mounted speaker.

(Prior Art) As shown in FIG. 1, conventionally, when a car-mounted stationary speaker 11 is placed on a rear tray 14, the rear wall part hits the rear glass 15 due to the vibration of the car, causing damage to the glass and speaker case. Some models have rubber 13 pasted on the rear wall 12 to prevent them from being scratched or making noise.

However, in the conventional case, the speaker case and the rubber must be in perfect contact with each other, which not only makes it difficult to control the dimensions, but also has the disadvantage that the adhesive part may peel off and stand up.

In addition, the rear tray becomes extremely hot due to direct sunlight, so heat-resistant measures are required for the adhesive, and in order to obtain a sufficient cushioning effect, the thickness of the rubber material must be increased, which increases costs. Of course, it also had the drawback of being restricted in terms of design.

(Purpose of the invention) The purpose of the invention is to eliminate the drawbacks of the conventional ones described above, and to provide a shock absorbing mechanism for a car speaker that is simple in structure, has a sufficient shock absorbing effect, and has an excellent design. Our goal is to provide the following.

(Structure of the invention) The shock absorbing mechanism in the vehicle-mounted speaker according to the present invention is such that a mounting recess is formed in the upper corner of the rear wall of the speaker case of the vehicle-mounted stationary speaker, and the mounting recess is formed in the upper corner of the rear wall of the speaker case. A rear wall external member having an external shape corresponding to the side corner portion is molded as a separate member and attached to the mounting recess through a cushion material made of foam, and the rear wall external member is connected to the external surface of the speaker case. They are arranged so that they are flush.

(Embodiment) An embodiment of the present invention will be described based on FIGS. 2 and 3. In the figures, 1 is the speaker case body, 2
is the rear wall portion of the speaker case main body 1, and in the case of a stationary speaker, the upper side corner portion in particular may come into contact with the rear glass of the automobile. Reference numeral 3 denotes a mounting recess formed in the upper corner of the rear wall portion 2, and as shown in the drawing, cushioning materials 5, 5 made of foam are provided at two locations on the vertical and horizontal sides of the mounting recess 3. At the same time, a rear wall outer member 4 formed of synthetic resin or the like as a separate part from the speaker case body 1 is attached via cushion members 5, 5. The outer shape of this rear wall outer member 4 is formed in a shape corresponding to the original outer shape of the speaker case body 1, and as shown in the figure, the outer shape consists of a vertical side wall, a horizontal side wall, and side walls on both sides. The speaker case body 1 has a surface 7 and is therefore arranged flush with the outer surface 6 of the speaker case body 1 .

(Effects of the invention) According to the shock absorbing mechanism of the in-vehicle speaker of the present invention, even if it comes into contact with the rear glass etc. and receives an impact, the impact is absorbed by the cushion material and the rear glass or case body is not damaged. , contact noise is also prevented.

In addition, by appropriately selecting the material and thickness of the cushion material, it is possible to obtain a desired cushion effect, and by using a material with adhesive treatment applied to the adhesive surface, the workability of assembly can be greatly improved. Improved.

Furthermore, if the rear wall outer part corresponding to the upper corner of the rear wall facing the rear glass is molded from the same synthetic resin as the speaker case, unlike conventional models where the rubber material is exposed, By painting, hot stamping, silk printing, etc. on the outer surface of this rear wall outer member, it is possible to easily perform an appearance treatment.
