BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to suikinkutsu, which have been conventionally installed in Japanese gardens and emit an extremely quiet sound of falling water at regular intervals, for example, once every second to several seconds.

0002

2. Description of the Related Art The present inventor has developed a suikinkutsu as shown in FIG. Suikinkutsu 1 with this structure allows water droplets to fall into the interior from the water droplet hole 2 at the top, and when the water droplets hit the surface of the water collected at the bottom, the impact sound reverberates inside the ceramic cavity, creating a unique and beautiful structure. Make a quiet sound that touches your heart. Suikinkutsu generates a unique sound by internally resonating the impact sound of water droplets falling on the water surface. This phenomenon is similar to the principle behind the impact sound caused by falling water droplets in a cave, which resonates internally. In other words, the sound emitted from the water droplets resonates in the cavity to create a unique sound quality.

The sound quality of a suikinkutsu varies significantly depending on its shape and the shape of the water hole that radiates the sound to the outside. In other words, the suikinkutsu forms a resonant circuit between the acoustic capacity made up of the internal cavity and the inertance made up of the water droplet holes. Acoustic capacitance and inertance affect the resonant frequency of the suikinkutsu and determine the sound quality.

0004

[Problems to be Solved by the Invention] In the conventional Suikinkutsu, a stone or the like is placed in the water hole, and the opening of the water hole is adjusted with the stone. You can adjust the sound quality of Suikinkutsu by placing the stones. However, it was difficult to adjust the sound to a comfortable level using this method, and the drawback was that not everyone could adjust the sound quality to the optimum level. Additionally, the water drop holes must be adjusted to allow water to fall at regular intervals. For this reason, the water drop hole has the drawback that it is difficult to adjust both the falling state of water droplets and the sound quality to optimal values.

Furthermore, the present inventor has developed a suikinkutsu which can be easily constructed (Japanese Patent Application Laid-Open No. 150999/1983). The suikinkutsu described in this publication has an overflow hole at its lower end. This structure has the advantage of keeping the water level in Suikinkutsu constant. However, this structure of the suikinkutsu has the disadvantage that the overflow hole opened at the bottom generates inertance connected to the acoustic capacity of the cavity, which affects the sound quality of the suikinkutsu.

[0006] The present invention was developed with the aim of further solving this drawback, and an important objective of the present invention is to provide a suikinkutsu that can always generate pleasant and clear sound.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. However, the embodiment shown below is an example of a suikinkutsu for embodying the technical idea of the present invention, and the suikinkutsu of the present invention has the materials, shapes, structures, and arrangements of the component parts as described below. It is not structure specific. The suikinkutsu of this invention can be modified in various ways within the scope of the claims.

[0010]Furthermore, in order to make the claims easier to understand, this specification uses numbers corresponding to members shown in the examples as "claims" and "means for solving the problem." It is added to the members shown in the "Column". However, the members shown in the claims are by no means limited to the members of the embodiments.

The suikinkutsu 1 shown in FIG. 1 is hollow and has a water drop hole 2 at the top and an overflow hole 6 at the bottom.

[0012] Suikinkutsu 1 has a height of, for example, 20 to 100 mm.
cm, with an inner diameter of 10 to 80 cmφ. Suikinkutsu 1 is designed to reflect sound well on the inside, for example.
Made of hard materials such as ceramics, porcelain, glass, earthenware, metal, and hard synthetic resin. Furthermore, the inner surface is finished smooth to improve the internal sound reflection rate. In the case of pottery, preferably
It is best to apply a top coat to the surface to make it smooth and glassy.

[0013] When the Suikotokutsu 1 is made of ceramic or metal, the material of the Suikotobota has a high Q value (a value indicating the energy of vibration consumed inside the Suikotobota when it is vibrated by the sound of water droplets) and produces the most beautiful sound. I can put it out.

The water droplet hole 2 is opened at the center of the upper end of the suikinkutsu 1. The inner diameter of the water drop hole 2 is, for example, 10 mm to 20 mm.
cmφ, preferably determined to be 20 to 10 mmφ. A draining ridge is provided at the lower end of the water droplet hole 2 along the periphery so that water does not flow down along the inner surface but falls from there as water droplets.

A water packing groove 3 for storing water is provided along the outer periphery on the upper surface of the water droplet hole 2. The water packing groove 3 has a width of 5 mm to 40 mm so that the lower end of the cup 4 can be placed there. Further, the depth of the water packing groove 3 is designed to be, for example, 5 mm to 50 mm so that the lower end of the cup 4 can be placed in water.

The cup 4 closes the water droplet hole 2 with a water packing structure. The lower opening edge of the cup 4 is placed in the water packing groove 3, and the water drop hole 2 is closed in a water packing state. Therefore, the shape of the lower opening edge of the cup 4 is similar to that of the water packing groove 3.
designed to have the same shape. Furthermore, the width of the lower edge of the cup 4 is designed to be narrower than the width of the water packing groove 3. The cup 4 can be made of the same material as the suikinkutsu 1.

Furthermore, the cup 4 has one to several sound holes 5 opened therein. The sound hole 5 radiates the sound resonated inside the suikinkutsu 1 to the outside. The shape of the sound hole 5 changes the sound quality produced by the Suikinkuku 1. For this reason, the sound holes 5 are designed to have a size, shape, and number that will give the suikinkutsu 1 the most desirable sound quality. The inner diameter of the sound hole 5 is preferably adjusted to a range of 1 mm to 10 mm.

The cup 4 shown in FIG. 2 has a sound hole 5 at its upper end and in the middle. When in use, this cup 4 is placed on the water packing groove 3 so that the middle sound hole 5 is located on the leeward side. The downwind sound hole 5 has the advantage of being able to effectively radiate generated sound.

The suikinkutsu 1 shown in FIG. 1 has an overflow hole 6 at its lower part. The overflow hole 6 stores water at a constant level at the bottom of the suikinkutsu 1 and causes water droplets to fall to the water surface. The position of the overflow hole 6 determines the water surface level stored in the suikinkutsu 1. The overflow hole 6 is opened at the bottom of the suikinkutsu 1 at a position where water is stored at a depth of several mm to more than ten centimeters.

A water pipe 7 is connected to the overflow hole 6. For the water pipe 7, a flexible hose or a hard pipe can be used. The water pipe 7 is bent downward and its lower end is opened into the water of the water container 14.

Although the suikinkutsu 1 does not specify a means for supplying a certain amount of water to the water droplet hole 2, as shown in FIG. 9, and guide the string 9 to the water packing groove 3 of the water droplet hole 2.
Water can be supplied to the water packing groove 3 of the water drop hole 2.

By using a plurality of strings 9 having different thicknesses and water absorption rates, each string drips water droplets at different time intervals, and irregular dripping sounds can be generated.

The suikinkutsu 1 of the present invention can also store a certain level of water at the bottom without providing an overflow hole. FIG. 7 shows a specific example. The suikinkutsu 1 shown in this figure has a suikinkutsu 1 whose lower end is open placed on a large dripping water receptacle 10. The dripping water receptacle 10 has a dish-like shape with an upper opening, an inner diameter larger than the bottom outline of the suikinkutsu 1, and a partition wall 11 having a height such that water can be stored at a predetermined depth.

The depth of water stored at the bottom of the suikinkutsu 1 can be determined by the height of the partition wall 11. This suikinkutsu 1 allows water dripped into the interior to flow into the dripping water receptacle from the bottom. The suikinkutsu 1 with this structure can store water in the entire bottom, and the bottom of the suikinkutsu 1 can be closed with water to improve the sound quality inside.

The suikinkutsu 1 allows water droplets to fall from the water droplet hole 2 and listens to the impact sound of the water droplets hitting the water surface. The impact sound of the water is reflected on the inner surface of the suikinkutsu 1 and resonates within the cavity of the suikinkutsu 1, producing a unique tone, such as a ping or a ding. Suikinkutsu 1, which resonates sound on its inner surface, is made of a hard material such as ceramics and reflects sound from the surface without absorbing it, causing sound to resonate within the cavity.

In the suikinkutsu 1 of the present invention shown in FIG. 1, the water drop hole 2 is closed by a cup 4 placed in a water packing groove 3 with a water packing structure. The water droplet hole 2 that is blocked in this state is
It prevents the free passage of air and allows the free passage of water. That is, the water droplet holes 2 that are closed with this structure are acoustically closed so that water can pass through them.

Furthermore, this suikinkutsu 1 has a sound hole 5 in the cup 4.
is open. The sound hole 5 connects the cup 4 to the water packing groove 3.
The opening is shaped to produce optimal sound quality when placed in the open position. For this reason, place the cup 4 on the water packing groove 3,
By allowing water droplets to fall into the interior from the water droplet hole 2, it is possible to always generate sound with optimal sound quality.

The cup 4 shown in FIG. 2 is provided with a water passage portion 12 at its lower edge so that water can easily pass therethrough. The cup 4 shown in FIG. 3 has a sound hole 5 opened near the water surface of the water packing groove, which also serves as a water passage section.

Furthermore, the cup 4 shown in FIG. 4 is provided with a water supply groove 13 around the top surface in which water can be stored. A center hole 15 is opened in the center of the water supply groove 13, and a sound hole 5 and a water passage part 12 are opened in the side part. This cup 4 is
Water supplied from a water reservoir 8 is temporarily stored, passed through a center hole 15, supplied to a water packing groove 3, and dripped from the water packing groove 3 into the interior of the suikinkutsu.

Furthermore, the cup 4 shown in FIG. 5 has a bottom plate 16 on the upper surface inclined downwardly toward the center, and has a center hole 15 in the bottom plate 16 and a sound hole 5 and a water passage part 12 in the side part. is open. The cup 4 having this structure allows water supplied to the upper surface of the bottom plate 16 to pass through the center hole 15 and fall into the interior of the suikinkutsu.

Furthermore, the cup 4 shown in FIG. 6 has a plurality of sound holes 5 on its outer periphery and a water passage portion 12 on its lower edge.

The suikinkutsu 1 shown in FIG. 1 also has a water pipe 7 connected to the overflow hole 6, and the tip of the water pipe 7 connected to the water container 14
It is connected under the water surface. Like the water droplet hole 2 described above, the overflow hole 6 having this structure can be acoustically closed while allowing water to pass through the overflow hole 6. Therefore, the overflow hole 6 does not adversely affect the sound quality of the suikinkutsu 1, and excellent sound quality can be generated.

[0033]

[Effect of the invention] The suikinkutsu of this invention can be easily and easily
The feature is that anyone can generate the optimal sound. This is because the suikinkutsu of this invention closes the opened hole in a water-packed state. The water packing can acoustically close the opening while allowing water to pass through, so it acoustically closes the opening of the suikinkutsu and allows water to pass through freely.
Suikinkutsu can achieve exactly the ideal conditions.

[0034] Since the water droplet makes sound by dripping water from the water droplet hole, the water droplet hole cannot be blocked. The open water droplet has a significant effect on sound quality depending on its opening state. Although the water droplet hole of the present invention is opened, it can be acoustically closed. Therefore, by opening a sound hole that provides the optimum sound quality in the cup that closes the water drop hole, it is possible to always generate the optimum sound quality.

Furthermore, a suikinkuku with an overflow hole has an adverse effect on the sound quality. The suikinkutsu of this invention can acoustically close the overflow hole while allowing water to pass through. Therefore, it is possible to realize the feature of improving the sound quality of the suikinkutsu by opening the overflow hole.
