Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a speaker panel board to a cabinet such as a tape recorder.

In order to attach a conventional speaker panel board 1 made of synthetic leather to a cabinet 2 of a tape recorder, etc. (see Figure 1), it is necessary to set up a welding rib and fix it by welding, or by using screws, adhesive, etc. Although it was stopped, it takes one assembly man-hour Jh'
Quality is unstable.

There were some drawbacks, such as if the installation was weak, the speaker panel would resonate and vibrate.

The present invention is intended to overcome the above-mentioned drawbacks and will be described in detail below with reference to embodiments shown in the drawings.

Engagement claws 1b are formed on the outer peripheral edge of the speaker panel plate 1 having the sound emitting holes 1a at appropriate intervals.

The speaker panel board 1 is further formed with a vibration-proofing convex portion 1c and an engaging convex portion 1d for preventing reverse rotation.

On the other hand, on the cabinet 2 side, an engagement hole 3 that engages with the engagement claw 1b and an engagement recess 4 that engages with the engagement protrusion 1d are bored.

The engagement hole 3 consists of a wide hole 3a that initially receives the engagement claw 1b, and a width pinched hole 3b that then tightly engages the engagement claw 1b when the engagement claw 1b is rotated.

That is, in FIG. 3, A>B.

Now, in order to attach the speaker panel board 1 to the cabinet 2, first, the engagement claw 1b is attached to the wide hole 3a of the engagement hole 3.

At this time, the engaging claw 1b is once bent inward (FIG. 4A), and then engaged as shown in FIG. 4.

Further, since the vibration-proof convex portion 1c of the speaker panel board 1 comes into contact with the front surface of the cabinet 2, the speaker panel board 1 is installed in a bent state (the center of the speaker panel board is in a bulged state).

Therefore, the engagement between the engagement claw 1b and the engagement hole 3 is strong, but in the present invention, the engagement claw 1b is rotated and the engagement hole 3
It is configured to be engaged with the width pinching hole 3b, and the mounting is more firmly fixed (see Fig. 5A).

At this time, since the engagement convex portion 1b for preventing reverse rotation is engaged with the deep groove portion 4b beyond the inclined portion 4a of the engagement recess 4, the speaker panel plate 1 is prevented from inadvertently rotating in the reverse direction. Prevented.

According to the present invention described above, the speaker panel board can be mounted extremely firmly without using any tools, the workability is good, and the structure is simple.
