Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for mounting an embedded car stereo speaker to a door or rear tray.

Conventionally, as a speaker device of this type, the one shown in FIG. 1 is common.

In the figure, reference numeral 1 designates a mounting plate for a rear tray, door, etc., which has a mounting hole 1a formed therein and a hole 1b formed at a position corresponding to a hole 3b of a speaker 3, which will be described later. Reference numeral 2 denotes a U-shaped mounting bracket, which is fitted into the hole 1b of the mounting plate 1. Further, a hole 2a is formed on the upper surface of this mounting bracket 2, and a tap 2b is formed on the lower surface side. Reference numeral 3 is a speaker, and the flange portion 3a of the frame is positioned on the upper surface of the mounting bracket 2, and the hole 3b is aligned with the hole 2a of the mounting bracket 2. Reference numeral 4 designates a ring-shaped grill mounting plate, which is placed on the upper surface of the flange portion 3a and is attached to the hole 3b of the flange portion 3a.
A hole 4a is formed in alignment with the hole 4a. Reference numeral 5 denotes a screw for attaching the speaker 3 and the grill mounting plate 4 to the mounting plate 1 via the mounting bracket 2, and 6 a grill that is detachably attached to the grill mounting plate 4.

By the way, in the case of the structure described above, all the holes 2a, 3b, 4a of the mounting bracket 2, the speaker 3, and the grille mounting plate 4 are aligned with the hole 1b of the mounting plate 1, and then they are mounted with the screws 5. Therefore, the installation work was difficult and very troublesome. In addition, since the screw 5 is installed outside the vibration diameter of the speaker 3, it is not possible to obtain a large vibration surface resistance even though the mounting hole 1a is large, even though it is advantageous to have a large vibration surface resistance in terms of sound quality and efficiency. There was a drawback.

The present invention is an attempt to correct the above-mentioned drawbacks, and the mounting is accomplished by attaching the mounting bracket to the mounting plate in advance and then rotatingly fitting the notch hole formed in a part of the flange of the speaker into the mounting bracket. The purpose of the present invention is to provide a speaker device that can perform the following functions.

Another object of the present invention is to provide a speaker device in which the mounting hole of the mounting plate can be made smaller than the diameter of the speaker diaphragm, and the size of the mounting hole does not require precision. be.

Next, an embodiment of the present invention will be described with reference to FIGS. 2 and 3. Note that the same symbols as in FIG. 1 indicate the same members,
Explanation will be omitted.

In this embodiment, reference numeral 7 is a U-shaped mounting bracket having a hole 7a and a tap 7b formed therein as in the conventional example, and an elastic claw 7c protruding from one side. The mounting bracket 7 is mounted in the hole 1b of the mounting plate 1 with a screw 5 so that the elastic claw 7c faces in one direction. On the other hand, speaker 8 is frame 8
Engagement holes 8b into which the elastic pawls 7c are inserted are formed at several locations in a, and a flange portion 8c is extended, and the outer peripheral end of a diaphragm 8d is attached to the flange portion 8c. Further, a falling piece 8e is formed on the outer periphery of the flange portion 8c, and the grill attachment plate 4 is attached to this by appropriate means, for example, by unevenness.

Next, to explain the operation based on the above structure, first, the mounting bracket 7 is mounted in the hole 1b of the mounting plate 1 with the screw 5 so that the elastic claw 7c faces in one direction. Next, the speaker 8 is inserted from above the mounting hole 1a, and the engaging hole 8b formed in the frame 8a is inserted into the lower surface side of the elastic claw 7c and rotated, so that the frame 8a is attached by the elastic force of the elastic claw 7c. The speaker 8 is fixed between the mounting plate 1 and the mounting plate 1.
Fixed. Therefore, the speaker 8 can be attached and detached by inserting it into the mounting hole 1a of the mounting plate 1 and rotating it without removing the screws, so assembly is very simple and the dimensions of the mounting hole 1a do not require much precision. Then, the grill mounting plate 4 is fitted onto the falling piece 8e of the flange 8c, and then the grill 6 is fitted onto the grill mounting plate 4, thereby completing the assembly.

As described above, in this invention, the mounting bracket is attached to the mounting plate in advance, and the speaker is mounted by inserting the engagement hole formed in the speaker frame into the elastic claw of the mounting bracket and rotating the speaker. Therefore, the mounting work is very simple, and the size of the mounting hole does not require precision, and drilling is also easy. Furthermore, by placing the mounting screws inside the diaphragm of the speaker, it is possible to use a speaker with a larger diaphragm than in conventional speakers, and the sound quality characteristics can also be improved.
