DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for generating sound with water droplets, and more particularly to a method for generating sound with a drip water using an instrument, and reverberating the sound in a housing. The present invention relates to a method and apparatus for generating a windy landscaping sound for enjoying the tone.

[0002]

2. Description of the Related Art Recently, in the field of landscaping, an environment-friendly nature-rich garden with a natural taste is about to be reviewed.

[0003] In order to generate sound in landscaping, it is generally known to use a "waterfall sound" or a "reversal sound of bamboo cans by soaking water". Can not be. On the other hand, generating a tone with a special instrument that leaves a lingering sound using water droplets, or generating a clear tone of the dripping water itself, can also enjoy the water sound of nature, an unusual taste Can be something.

[0004] As a conventional technology using the sound of dripping water,
It is disclosed in JP-A-63-254494. However, this prior art is also a water drop sound itself dropped on water, and does not particularly enjoy reverberation sound. Further, the above-described device is a decorative article for indoor use, and is not used for garden.

[0005] On the other hand, the Suikoto cave (also called cave sluice), which was used in old Japanese gardens, only survives today. However, because of its beautiful tone, it has been reconsidered in modern times and has been reverberating.

[0006] The Suikin cave is a buried cave body in the ground, a basin is placed in the cave body, water drops are dropped on the upper surface corresponding to the bottom of the basin, and the sound of the dripping echoes inside the cave body. They enjoy hearing the sound leaking to the ground.

[0007] However, when Suikin Grotto is applied to an existing garden,
It is necessary to dig a deep hole in the well-maintained garden and installation is difficult. Further, since the sound changes delicately depending on the arrangement of stones and rocks buried in the walls and the like of the cave body, there has been a grudge that cannot guarantee the customer that the desired sound can be emitted in advance. Moreover, the sound of water drops falling on the upper surface of the basin has a drawback that it is difficult to hear because the sound is very small even when dropped at a considerable interval.

[0008]

In view of the above circumstances, the present invention can be applied to existing gardens, can be a standard product, and emits a beautiful tone that is easy to hear. It is an object of the present invention to provide a method and apparatus for generating sound using water droplets.

[0009]

According to the present invention, in order to achieve the above object, an apparatus for emitting sound is provided in a housing, a water drop is dropped into the housing, and the sound is generated by the above-mentioned equipment with the dropped water. A method and an apparatus for generating a sound and generating a sound with water droplets by causing the generated sound to reverberate.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic front view showing the inside of an embodiment of a method of generating sound by water droplets according to the present invention, and FIG. 2 is a schematic plan view of FIG. 1 cut along the AA plane.

The housing 1 is 150 mm wide and 1150 m long.
It is made of a stainless steel box having a depth of about 300 mm. Of course, the size can be appropriately designed as needed, but it is necessary that the size is such as to emit a preferable reverberation sound. Also, in some cases, a long tube such as a horn may be used to make the eco-friendly sound heard. The shape may be a cylindrical shape other than a rectangular shape, a round shape, or an elliptical shape.
The material is also preferably made of stainless steel in the case of this embodiment in consideration of corrosion and reverberation due to water, but is not limited thereto, and may be made of plastic, ceramic, glass, or other metal. You can also.

In order to produce good sound effects,
The reflected sound and the reverberation time may be considered. For that purpose, modern music halls have irregularities on the walls and ceiling to absorb the direct reflected sound, while the reverberation is improved, as required on the inner surface of the housing 1 as necessary. An uneven surface or a sound absorbing material may be provided. When the casing 1 is produced in a factory, the casing 1 becomes somewhat large, so that it is preferable that the casing 1 be easily assembled locally.

An instrument 2 for emitting sound is provided in the housing 1. In this embodiment, the instrument 2 that emits sound is a musical instrument that plays (repels) a sound plate. The musical instrument that plays the sound plate is not a pre-existing musical instrument, but a musical instrument that can be referred to as a standing harp 4 holding a sound plate 3 made of a thin metal plate in a cantilever shape. The tip 3a of the sound plate 3 is played with a claw 5 resembling a koto claw, and the sound plate 3 vibrates to produce a beautiful tone, which is hardly included in the category of stringed instruments or percussion instruments.

However, the instrument 2 that emits a sound according to the present invention is not limited to a special musical instrument that plays the sound plate of the present embodiment, but is a floor instrument other than a wind instrument, in which a water bottle urn is placed face down. Water-resistant stringed percussion instruments such as pots, bells, orchestras, orchestras, kotos, and metal xylophones can also be used. In the case of a basin pot, it is preferable to use a porcelain made of Bizen ware, Arita ware, celadon porcelain, glass, stainless steel, or the like that emits a high tone.

As a means for intermittently flowing water in the garden, a water basin or a squatting (tsukubai) dropping means 6a is provided. Also, as a means of flowing water directly,
It is the one under the waterfall that flows artificially or naturally.
Corresponding to these means, the housing 1 is buried underground Ug. However, this is not limited to underground, and the housing 1 can be laid on the ground.

The former water drop 7a from a water basin or the like enjoys the sound of an intermittent drop when water is dropped with a scoop or the like. On the other hand, the water droplet 7b from the latter waterfall or the like is a continuous drop. In the case of the present embodiment, the water droplets 7b are configured to flow continuously from the tip of a kakehi (Kakehi) 8 composed of a bamboo tube gutter. Therefore, the sound generated in the case of the present embodiment is due to the water accumulated in both the water droplets 7a and 7b. Of course, one of the water droplets 7a from a water basin or the like and the water droplets 7b from a waterfall or the like may be used.

The lower surface 1a of the housing 1 may be a stainless steel plate with good sound reverberation or a smooth surface such as a granite plate made of granite. Alternatively, irregularities such as pebbles may be laid to absorb the reflected sound to give a subtle change in tone. A drain port 9 is provided at one end of the lower surface 1a of the housing 1.

Axial columns 10, 1 are placed on a flat lower surface 1a of the housing.
An arm 12 is rotatably mounted on a bearing 11 at an upper portion between the two shaft pillars 10 and 10. A water receiving tray 13a for receiving water drops 7a and 7b is mounted on one end 12a of the arm 12, and the above-mentioned claw 5 is mounted on the other end 12b of the arm 12. The claws 5 may be pointed at the other end 12b of an arm made of stainless steel or the like. However, since the claws 5 are repeatedly worn by the sound board 3, the claws 5 are made of a more durable bee-like bone. It may be made of diamond stone.

Accordingly, when a full cup of water accumulates in the water receiving tray 13a, the arm 12 is lowered at the one end 12a side of the water receiving tray 13a in the direction of the arrow Ar to the position 13b. At this time, the other end 12b of the arm 12 rises in the opposite direction.
The claw 5 attached to the sound plate 3 also rises in a circular arc, so that the claw 5 emits a sound by playing the tip 3a of the sound plate 3. Sound board 3 for that
Are also arranged in an arc shape along the operation locus of the claw 5.

Since the arm 12 is balanced so that the other end 12b side becomes heavy, the water 1 in the water receiving tray 13b is
4 is discharged, the one end 12a rises and the water pan is
It rises again to the position of 3a. Therefore, at this time, the other end 12b of the arm and the claw 5 descend in the direction of the arrow Br.
Again, the claw 5 is used to play the tip 3a of the sound plate 3 to emit a sound. For this reason, the other end 12b side is considerably heavy, and the claw 5 and the tip 3a of the sound plate 3 are lightly touched so that little resistance is applied.

As described above, the arm 12 is made of a material similar to water supply, which enjoys the intermittent sound of the bamboo tube falling.
In addition, it may be made of wood, synthetic resin, or metal. Elastic bodies 15, 15 are attached to positions where the lower portions of both ends 12a, 12b of the arm 12 are in contact with the lower surface 1a of the housing.

On the upper surface 1b of the housing, the ground is prepared with rocks, pebbles, sand, moss 16 and the like so as not to make the garden feel uncomfortable. However, a water gate 17 is formed in the upper surface 1b of the housing 1 so as to be recessed so that the water drops 7a and 7b can enter therein, and a repair lid 18 is mounted on the claw 5 so as to be openable and closable. In addition, although not shown, a hole or a net-like net for leaking the tone color may be additionally provided.

The small water drops 7a and 7b flowing from above are dropped into the housing 1 from the position of the water gate 17 and the water 7
a and 7b are stored in the water tray 13a.
The water 14 inside is full. Then, the weight of the one end 12 a side of the arm 12 is reduced by the water 14.
Since it becomes heavier than the b side, the water tray is lowered, and after the water 14 is discharged at the position 13b, it is restored to the original position. During the vertical movement during this time, when the claw 5 at the tip end of the other end 12b reciprocates on the sound plate and plays, a striking sound of a beautiful tone is emitted.

The method of the present invention in which a sound emitting device generates sound using dripping water and echoes the generated sound is not limited to the present embodiment. For example, it is also possible to directly drop dripping water on the upper surface of a basin or the like, or to make a sound by indirectly hitting the side of the basin or the like with an L-shaped arm of a water-supplying swing type. .

In order to emit sound using water droplets, it is necessary to appropriately adjust the frequency characteristics of the emitted sound, the arrival time of the reflected sound, and the extent to which the echo of reverberation time and delay is prevented. Can be. Therefore, various means can be adopted because the characteristics vary depending on the specification of the housing 1. In this manner, a desired beautiful tone can be emitted. It is included in the range.

The sound generated at the properly adjusted drop water interval reverberates greatly in the cavity of the housing 1 as described above, and the sound is eventually leaked to the ground. At the time of this leakage, it is also preferable to provide a chimney-shaped cylinder. Its tone is clear and high-pitched, and the synthesized reverberation has a long tail, making it a beautiful, clear tone that you can not think of the sound of this world, which you have never heard on other instruments before. Emitted to

In the above-described embodiment, since the claw 5 is used to play the tip 3a of the sound plate, it is necessary to store a considerable amount of water in the water receiving tray 13a. Will be. In this regard, the next embodiment can enjoy continuous sound.
