Description

[Detailed description of the invention] The present invention relates to a decorative speaker whose decorative exterior is made of trays.

Nowadays, as production sites become highly rationalized and social institutions become increasingly complex, various types of stress are increasing, and the use of background music as a countermeasure has become popular. There is. This background music is
If you hear it coming from somewhere at a relatively low volume, it can be a good way to calm your irritated nerves.

The purpose of the present invention is to provide a decorative speaker that is effective for use in such cases. It is made of a plastic foam material, has a storage hole in which the enclosure is stored upward from the bottom surface, has a resonant space inside that communicates with this storage hole, and has a resonant space connected to the enclosure corresponding part on the top surface. A filling material having a large number of pores penetrating into the resonance space, a through hole penetrating into the resonance space from a portion slightly away from the enclosure corresponding part, a dustproof net disposed on the filling material, and the dustproofing net. An imitation bon tree formed using a wire stuck into the filling material from above the net, an imitation moss placed on the dustproof net in the through holes and pores, and the remaining dustproof net are filled. The gist of this is that it consists of soil for use in trays.

A detailed description will be given below with reference to embodiments shown in the drawings.

Fig. 1 is a longitudinal sectional view of one embodiment of the present invention, Fig. 2 is a plan view of the dustproof net with the top removed, and the longitudinal sectional view of Fig. 1 is shown in Fig. It is cut along the line.

In the drawing, 1 is a flower pot, 2 is an enclosure, 3 is a speaker unit, 4 is a filling material, 5 is a dustproof net, 6 is an imitation bon tree, 7 is an imitation moss,
8 is the soil for bonsai. The flower pot 1 is a very ordinary tray pot, and the enclosure 2 containing the speaker unit 3 is fixedly arranged at the bottom of the flower pot 1. The method of fixing the enclosure 2 can be selected as appropriate, such as by screwing or by adhesive. Further, the upper surface of the enclosure 2, that is, the part where the sound generating surface of the speaker unit 3 is exposed, is covered with a punch plate 21, which is a metal plate with numerous fine holes, to protect the speaker unit 3.

The filling material 4 is filled into the flower pot 1 in which such an enclosure 2 is installed, and has a three-layer structure of a lower layer material 41, a middle layer material 42, and an upper layer material 43, and is made of, for example, hard polyurethane. It is made of foam-like plastic foam. A storage hole 44 for storing the enclosure 2 installed at the bottom of the flower pot 1 is bored through the lower layer material 41 at a position corresponding to the enclosure 2 installed at the bottom of the flower pot 1. Further, the middle layer material 42 acts as a frame for forming a resonance space 45, and the storage hole 44 communicates with this resonance space 45. Furthermore, a large number of pores 46 penetrating to the resonance space 45 are bored in a portion of the upper layer material 43 located directly above the enclosure 2 . This pore 4
Two through holes 47 are drilled in the upper layer material 43 in the vicinity of 6, that is, in a portion slightly shifted from directly above the enclosure 2. Two through holes 47 that reach the resonance space similarly to the pores 46 are bored. . These pores 46 and through holes 47
The diameter of the pore 46 is approximately several millimeters, and the diameter of the through hole 47 is approximately 30 mm, which is several times that diameter.The sound generated by the speaker unit 3 is led out to the outside world through the pore 46 and the through hole 47. be done.

The dustproof net 5 is a fine mesh material disposed so as to cover the surface of the filler 4 filled in the flower pot 1 in this way, and is made of, for example, Saran net.

The imitation bonsai 6 is formed around the core 62 by twisting together four wires 61 that are stuck into the filling material 4 from above the dustproof net 5. That is, by attaching hard urethane foam or paper clay to this core 62,
It is shaped like a tree, such as an old pine tree, and its surface is covered with imitation bark. In Figure 1, this imitation bonsai 6
shows only the root part and omits the upper part.

The imitation moss 7 and the tray soil 8 are placed so as to cover the exposed part of the dustproof net 5 on which the bonsai tree 6 is planted and placed, and the imitation moss 7 is placed over the through hole 47 and They are placed over the pores 46, and placed so that the tray soil 8 does not rest on them as much as possible. In this case, care must be taken not to spoil the overall appearance of the tray. This imitation moss 7 is, for example, a mass of green fibrous material, has good ventilation, and has a structure that does not affect the sound coming out from the through holes 47 or pores 46. . Further, as the potting soil 8, for example, colored sawdust hardened with adhesive is used.

According to the decorative speaker configured in this way,
The speaker unit is buried in a flower pot and is completely invisible from the outside, and although it is a replica, it is a fine tray design, and its visual effect as an interior decoration is extremely high. In addition, the speaker unit is housed in an enclosure, and a resonance space is provided in the filling material, and the structure is such that sound is led out from this resonance space through holes or pores. Therefore, sound congestion, distortion, attenuation, etc. are minimized, and extremely good sound quality can be obtained. Furthermore, the large-diameter through-holes are drilled at a position slightly shifted from the position directly above the speaker unit, and only the small-diameter pores are drilled directly above the speaker unit, so that the surface of the filler material is The covering dustproof net and the punch plate on the top of the enclosure work together to prevent dust from falling onto the speaker unit during manufacturing.
This punch plate also has the role of protecting the wire that forms the core of the bonsai tree from getting stuck in the speaker unit.

Although the present invention has been described above in detail based on the illustrated embodiments, it goes without saying that the present invention is not limited thereto. For example, the filler has been described as having a three-layer structure, but it may also have a two-layer structure that integrates a lower layer material and a middle layer material, or an upper layer material and a middle layer material.
Various variations are possible, such as one that is divided into two in the vertical direction, and one that is formed as a whole. In addition to this filling material, materials other than those in the examples can be selected as appropriate for materials such as imitation bonsai, imitation moss, and soil for bonsai. You can also use natural materials such as Akadama clay or river sand as soil for tray making.

As explained in detail above, according to the decorative speaker according to the present invention, the enclosure housing the speaker unit is completely hidden inside the tray-shaped flower pot, resulting in an extremely visually superior product. Not only does it look great as a room decoration, but if you play background music from this decorative speaker, you can hear beautiful music coming from everywhere, making it ideal for soothing tired nerves. Furthermore, since the speaker unit is housed within the enclosure and there is a resonant space inside the filling material in which the enclosure is housed, the sound quality is also extremely excellent.
