Description

[Detailed Description of the Invention] The present invention relates to the howling phenomenon when using audio electrical equipment and to an audio rack that can smoothly open and close the front door.

Conventionally, due to the design of audio racks, as shown in Figure 1, the depth of the sides is 8, with the rear half being the side plate 8.
The front half is fitted with a glass plate 1, and the rear half of the shelf board 7 on which audio equipment is loaded is supported by the side board 8. However, when the front half is suspended from the upper frame, the front part of the top board 5 The problem is that the front door hangs downward, making it difficult to open and close the front door smoothly.
As shown in the figure, cushion rubber 3 was pasted on the upper and lower end surfaces of the glass 1 and fitted into the groove bottoms of the upper and lower side frames having a U-shaped cross section, but this had the disadvantage of causing a howling phenomenon when audio equipment was used.

The present invention was devised to eliminate the above-mentioned drawbacks, and if the embodiment shown in the drawings is explained, it will be explained as follows.
As shown in the figure, this is an audio rack in which a plate spring 2 having cushion rubber 3 adhered to both upper and lower surfaces is inserted between the groove bottom of a side upper frame 4 having a U-shaped cross section and the upper end of a glass 1. A shaft is attached to the core end of the plate spring 2, a knob 6 is attached to the shaft, and the knob 6 is rotated left and right to adjust the glass 1 so that there is no gap between the top end of the glass 1 and the bottom of the groove of the upper frame 4. It is.

Since the present invention has the structure described above,
The glass 1 is tightly fixed to the upper and lower side frames, which reduces howling phenomenon when using audio equipment, reduces sagging of the top plate 5 toward the front, and is industrially beneficial because the front door can be opened and closed smoothly. This is a great idea.
