Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to audio equipment such as electronic organs and speaker systems, and the sound output is improved by covering a through hole for a handle provided in a cabinet with a thick cover made of soft resin foam. This is designed to solve various problems such as being able to see through the inside without causing any adverse effects.

In general, for heavy acoustic equipment such as spinet-type and electronic organs, a part of the back plate 2 provided on the back side of the cabinet 1, as shown in Figure 1, is used to facilitate transportation. Through-holes 3, 3 for handles are provided, and fingers are inserted into these holes for conveyance.

However, if this hole 3 is left as is, the hole 3
There are problems such as internal parts being visible through the openings, internal light leaking out resulting in poor appearance, dirt and dust entering the interior through the through holes 3, and children throwing various foreign objects. Especially when metal objects such as coins or nails are thrown into the device, there is a problem that an unexpected short circuit may occur.

Furthermore, in large cabinets such as electronic organs, mice often enter through the holes 3 and build nests inside the organ, or chew on the internal wiring, causing defects.

, 21 The present invention provides an audio device that solves these problems with a simple configuration.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4.

Figures 2 to 4 show the area around the through hole of an embodiment of the present invention, where -2 is a back plate, 3 is a through hole for a handle, and 4 is a cover that covers the entire surface of the through hole 3. be. This cover 4 is made of a soft resin foam such as urethane, and only the lower side 4 is covered with double-sided tape, adhesive, or tacker! It is fixed to the inner surface of the back plate 2 using well-known means such as screws. This cover 4 hardly flexes when pushed by an infant's finger or a mouse, but only flexes as shown by the broken line in Figure 2 when pushed relatively strongly, and when the pushing force is removed, it flexes completely. It is desirable to have flexibility to the extent that it can be restored to its original position, and if urethane foam is used, the
It is desirable to have a wall thickness of about L.

In this way, as shown in Fig. 4, the through hole 3
When the finger 5 is inserted into the cover 4, the upper side of the cover 4 bends toward the inside of the back plate 2, and the upper end of the through hole 3 can be easily inserted.
Since the cover 4 itself is still made of a soft resin foam, the finger 6 will not be damaged even when the finger 6 is pulled out. After the finger 6 is removed, the cover 4 is restored to its original state, so it can always cover the through hole 3. Therefore, the inside can be seen, children can throw foreign objects, and mice can Problems such as getting in can also be effectively prevented.

Note that it is also possible to configure the cover with a thin sheet with appropriate flexibility, but in this case, the upper free end of the cover resonates with the sound output direction and vibrates. There is a problem in that chattering noise is generated between the inner surface of the back plate and the inner surface of the back plate. However, if the cover 4 is made of thick urethane foam as in the above embodiment, the upper end of the cover 4 will not resonate with the acoustic output, and therefore an excellent effect will be obtained in that no chattering noise will be generated. I will protect you.

Further, the present invention is not limited to electronic organs, but can also be applied to speaker boxes of speaker systems, etc.

As described above, the present invention covers a through hole for a handle provided in a part of a cabinet with a thick cover made of soft resin foam fixed to the inner surface of the cabinet only at the lower side. Because of this, it is possible to solve problems such as the inside of the cabinet being visible through the through hole or foreign matter getting inside the cabinet with an extremely simple configuration. Moreover, since the cover is made of a thick foam made of soft resin, the free end of the cover resonates with the acoustic output and vibrates, which eliminates the problem of chattering noise. You can get the same effect.
