Description

Technical Field

[0001] The present invention relates to an upper open-top building structure having an upper open space in the center of the building plane, and more specifically, to a structure in which, when outdoor activities such as music performances, speeches or weddings are held in the open space, the sound produced on the central stage is amplified by itself through the sound aggregation and resonance phenomenon caused by the characteristics of the building structure, so that the audience or the spectator can hear the pure original sound at a satisfactory volume without the need for other speakers or amplifiers. In addition, in terms of sound quality, the structural characteristics of the building structure produce clear and transparent optimal reverberation by inducing sound reflection and sound absorption, and interfering with appropriate harmony. Background Art

[0002] In the past, various activities such as concerts, weddings, cultural activities, lectures, speeches, etc. were generally held in indoor theaters. However, recently, in order to pursue a sense of openness, uniqueness, and a free atmosphere, there has been a trend of moving away from indoors and holding them outdoors. In this way, when performing outdoors, since the audience's movements are not restricted, it can create a free atmosphere and give the audience a sense of individuality and freshness, which is an advantage. However, there are the following disadvantages: basically, it is very sensitive to the influence of weather and climate, and unlike the closed space indoors, the sound will be transmitted to the open external space as it is, resulting in a large sound loss, and the sound cannot be transmitted to the audience well.

[0003] In particular, the acoustical shortcomings that are problematic during outdoor performances are described in more detail as follows: when playing or performing indoors, the sound produced on the stage is reflected by the walls, ceiling, and floor, and the reflected sound reverberates in the closed indoor space to produce reverberation, thereby allowing the fullness of the sound and the sense of space to be felt. In contrast, during outdoor performances, since the sound produced on the stage diffuses to the open outside without being reflected, the sound loss is large, making it difficult to enjoy the full volume, and since there is no echo, the sound is transmitted to the audience with a poor and dry feeling. In addition, from the perspective of the performer, when performing, it is necessary to perform while listening to the sound of one's own performance, but during outdoor performances, since the sound of one's own performance or singing cannot be transmitted back to the performer through the reflected sound, it is difficult to monitor the performance. Instead, the performer hears the chaotic noise around him, causing the performer's concentration to decrease, making it difficult to perform at a high level.

[0004] Therefore, in the past, in outdoor performances and other activities, it can be said that other sound equipment such as speakers and amplifiers are necessary so that the audience can hear the sound of the performance on the stage at a sufficient volume. Therefore, there are the following disadvantages: the above-mentioned sound equipment needs to be set up in advance, and it takes a lot of time, cost and effort to recover it after the performance. For the audience, what they hear is not the pure original sound of the performance on the stage, but the sound coming out of the speakers, which leads to reduced audience satisfaction.

[0005] In addition, when performing indoors, the original sound of the stage is listened to while the reflected sound and reverberation sound from the walls, floor, ceiling, etc. are appreciated, so the sound feels three-dimensional and rich. However, when enjoying the performance through the above-mentioned audio equipment, since the sound is enjoyed through the speakers set at the predetermined positions, the sound coming from the speakers feels flat and dry compared to the above-mentioned indoor performances. In order to solve these problems, in addition to the main speakers, multiple independent surround speakers were arranged on the periphery of the performance venue to artificially produce effects similar to reflected sound and reverberation sound. As representative examples of the above-mentioned prior art, Korean authorized utility model No. 20-0295451 and No. 20-0316692 can be cited.

[0006] The prior granted utility model discloses a system and a speaker device for adding outdoor reverberation, such as Figure 6 As shown, the prior authorized utility model, in addition to a main speaker that directly outputs sound, has multiple initial reflected sound speakers and reverberation sound speakers, and these speakers are arranged around an outdoor performance venue. Therefore, during outdoor performances, an effect as if a reflective wall is set up around the performance venue is artificially created, and the sense of space that can be felt in an indoor performance venue through reflected sound and reverberation sound can be obtained.

[0007] However, according to the prior art as described above, there are the following problems; namely, due to the additional installation of the above-mentioned loudspeakers, the cost required for the performance is greatly increased, and each outdoor performance requires skilled technicians to install and dismantle the sound equipment, so the preparation and cleaning work before the performance requires a lot of time and effort. More importantly, in terms of sound, although the effects of reflected sound and reverberation sound are indirectly created by installing additional loudspeakers, there are limitations in using such artificial effects of loudspeakers to produce the three-dimensional sense and aftertaste of indoor performances. Summary of the invention

[0008] Technical issues

[0009] Therefore, the problem to be solved by the present invention is to provide a building structure, when a music performance, speech, wedding or other event is held outdoors, due to the structural characteristics of the building, the sound produced on the central stage will be amplified by itself, so that the audience or the audience can hear it at a clear and satisfactory volume just like an indoor performance. Therefore, even in the absence of other audio equipment such as speakers or amplifiers, outdoor performances and other activities can be carried out.

[0010] In addition, another object of the present invention is to provide a building structure that can improve audience satisfaction when holding outdoor activities because the audience can enjoy pure original sound without the aid of audio equipment. In particular, in terms of sound quality, the clear and transparent optimal reverberation can be produced through appropriate coordination of sound reflection, sound absorption and interference.

[0011] Means of solving the problem

[0012] In order to achieve the above-mentioned technical problems, the sound space architectural structure provided by the present invention is an upper open architectural structure constructed and installed on a reference ground, with a point on the reference ground as the center point on the plane, wherein the structure includes: a plurality of sound guide blades erected on the upper part of the reference ground at predetermined intervals, and arranged radially at a distance from the center point on the reference ground, and forming a curved frame shape on the plane as a whole; a sound reflection wall, which is a wall structure erected on the reference ground and is arranged to be connected to the sound guide blades, forming the same curved shape as the sound guide blades on the plane, and forming a predetermined sound space on the inside; and a rooftop auditorium, which is set at a predetermined height from the reference ground, and is extended in the upper part of the sound reflection wall in the opposite direction relative to the center point on the plane of the reference ground.

[0013] Here, the sound guide blade plate is a cylindrical component connected up and down with a cross-sectional shape having long sides and short sides as a whole. The sound guide blade plates are arranged radially so that the long sides of their cross-sections are respectively directed toward the center point on the plane of the reference ground, and are arranged so that all or part of the cross-section of the sound guide blade plate protrudes from the surface of the sound reflection wall toward the center point on the plane by a predetermined length.

[0014] Here, preferably, the sound guide vane plates are respectively installed at the same distance from the center point of the reference ground, so that, when viewed from above, they are in a perfect circular shape or an arc shape with one side partially open.

[0015] Moreover, as a more preferred structure of the sound space architectural structure of the present invention as described above, the sound-guiding blade plate can be made of a material having a higher sound absorption coefficient than the sound-reflecting wall, or a sound-absorbing finishing layer is further provided on the surface of the sound-guiding blade plate, and the sound-absorbing finishing layer is made of a material having a higher sound absorption coefficient than the sound-reflecting wall plate.

[0016] Furthermore, according to the sound space architectural structure of the present invention, horizontal sound guide vane plates having the same cross-sectional shape as the sound guide vane plates may be further arranged between the sound guide vane plates in the horizontal direction.

[0017] Effects of the Invention

[0018] As described above, the sound space architectural structure according to the present invention has the following advantages; namely, when music performances, speeches, weddings and other activities are held outdoors, the sound produced on the central stage will be amplified by itself through the sound aggregation and resonance phenomenon caused by the structural characteristics of the building. Therefore, just like indoor performances, the audience or spectators can hear it at a clear and satisfactory volume. When performing outdoor performances, even if there are no other audio equipment such as speakers or amplifiers, the audience can enjoy the stage performance sound in a purely original state, thereby greatly improving the audience's satisfaction.

[0019] Moreover, the sound space architectural structure according to the present invention as described above has the following advantages; namely, in terms of sound quality, the original stage sound, resonance sound and reverberation sound can be heard at the same time, thereby overcoming the problem that the sound of outdoor performances sounds monotonous and weak. Just like indoor performances, rich sounds with three-dimensional sense, resonance and aftersound can be enjoyed. In addition, according to the preferred structure of the present invention, reflected sound, sound absorption and interference are properly coordinated, thereby creating the advantages of appropriate echo and clear and transparent optimal reverberation.

[0020] Moreover, for performers on the central stage, when performing outdoors, it is generally difficult to monitor their own performances because the performance sounds are transmitted as is to the open outside. To address this problem, the sound space architectural structure according to the present invention has the following advantages: namely, through reflected sound, the performers can monitor the performance while listening to their own performance sounds. In addition, the height difference between the performance stage and the auditorium can block the ambient noise transmitted to the performers, thereby helping the performers to maintain their concentration and maintain a very high level of performance.

[0033] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

[0034] The present invention relates to an atrium-type building structure, which is a building structure constructed on the ground, and in the plane, the central part of the building has no ceiling but the top is open, and has a space of a shape formed by surrounding buildings. In particular, the present invention constructs a sound space in structure, so that when outdoor performances and the like are performed in the space with the top of the atrium open, the audience listening to the performance can feel the sense of space and reverberation sound as if it were performed in an indoor space without the need for other audio equipment.

[0035] Figure 1 is a top view of the sound space architectural structure of the present invention, Figure 2 is a three-dimensional cross-sectional diagram, such as Figure 1 and Figure 2As shown, the sound space architectural structure of the present invention, as a basic structure as a whole, includes: a plurality of sound guide blade panels 10, which are erected on a reference ground 100 at predetermined intervals and are arranged to be in a curved frame shape on a plane as a whole; a sound reflection wall 20, which is connected to the sound guide blade panels 10 and has the same curved shape on a plane, forming a sound space 200 surrounded by the inner side of the wall surface; and a rooftop auditorium 30, which is extended in the outer direction of the arc center CP at a predetermined height above the sound guide blade panels 10 and the sound reflection wall 20 erected as described above, and also includes a sound source stage part 50 arranged in the center part on the reference ground 100.

[0036] In addition, according to Figure 1 and Figure 2 In the embodiment shown, in the sound space architectural structure of the present invention as described above, the sound guide blade plates 10 are arranged radially on the reference ground 100 with the center point CP on the plane as the arc center at a predetermined distance, and when the sound guide blade plates 10 are connected to the reflection wall 20, they are arranged in a form of protruding a predetermined length from the wall surface of the sound reflection wall 20 to the inside (i.e., the arc center direction).

[0037] Each component constituting the sound space architectural structure of the present invention according to the above-mentioned structure will be described in more detail with reference to the accompanying drawings.

[0038] First, the sound guide blade plate 10 is a columnar component erected on the reference ground 100. In the sound space architectural structure of the present invention, the sound guide blade plate 10, such as Figure 1 and Figure 2 As shown, a plurality of sound guide blades are arranged on the reference ground 100 at predetermined intervals. At this time, the plurality of sound guide blades 10 are arranged radially at a predetermined distance from a point on the reference ground 100 as a center point CP, so as to be arranged as follows: Figure 1 The frame structure shown is curved in plane.

[0039] In addition, if Figure 1 and Figure 2As shown, the sound guide vane 10 is a columnar member having a predetermined cross-sectional shape connected vertically, wherein the cross-sectional shape of the sound guide vane 10 is a rectangular columnar shape having long sides and short sides, and the alignment direction is respectively set such that the long side direction faces the inner space direction, that is, the center point CP on the plane of the reference ground. That is, as described in more detail in the effect of the present invention described later, in the present invention, the sound generated from the central sound source stage 50 is reflected by the sound reflection wall 20, and the reflected sound is concentrated to the central part while generating a resonance phenomenon (in the present invention, the amplification effect generated by the sound concentration is called the sound focusing effect), so that a large volume can be obtained without an audio device, and in the present invention, it is particularly considered that, as mentioned above, by directing the direction of each sound guide vane 10 toward the center point CP, the diffused reflected sound is maintained to a certain extent, and the direction of the reflected sound is concentrated to the central part, so that the sound focusing phenomenon as mentioned above can be smoothly obtained.

[0040] On the other hand, according to Figure 1 and 2 In the embodiment shown, when the sound guide vane plate 10 is installed on the reference ground 100, it is installed at the same distance from the center point CP on the plane of the reference ground, so it can be set in an arc shape with one side open when viewed from above. That is, according to the main technical features of the present invention, as described later, by connecting the sound guide vane plate 10 to the sound reflection wall 20, the sound generated in the sound space 200 is reflected and returned in the direction of the sound source stage part 50, but unlike Figure 1 Unlike the embodiment shown, if the distances of the plurality of sound guide blade plates 10 from the center point CP on the plane are different and have some gaps, there will be a time difference in the time when the reflected sound from the sound reflection wall 20 reaches the center point CP. Therefore, the reflected sound of the same content arrives continuously from different directions with time differences in a relay manner, which will cause the performers performing on the sound source stage portion 50 to hear an echo like a reverberation.

[0041] Therefore, in order to prevent the time difference of the reflected sound as described above from causing confusion to the performer, Figure 1 As shown in the embodiment, the sound guide blade plate 10 is set at the same distance from the arc center CP, and is particularly preferably configured in a circle. When the above-mentioned problems are considered, it can be configured as other curved shapes such as an ellipse, rather than a perfect circle or an arc. However, it should be understood that these embodiments do not basically depart from the technical idea of ​​the present invention and all belong to the technical scope of the present invention.

[0042] on the other hand, Figure 1In the case of setting the sound guide vane plate 10 as described above, the circular arc shape is set to open a part of the circle, and the lower side is opened by about 90° in the figure. Figure 1 As shown, when the sound guide blade plate 10 is configured as an arc shape with one side partially open on a plane, the open angle range is preferably within a range of no more than 120° from the center of the arc. If it is opened beyond this range (for example, a semicircular plane), it is difficult to fully achieve the sound gathering effect of the main technical feature of the present invention, so it is not preferred.

[0043] In addition, according to the structural feature of the present invention, when the sound guide vane 10 is provided, the sound guide vane 10 is preferably made of a material having a higher sound absorption coefficient or absorption coefficient than the sound reflection wall 20 described later in terms of sound absorption performance. That is, as described above, in the present invention, the sound guide vane 10 is a structure for concentrating the sound reflected from the sound reflection wall 20 toward the center to induce the sound gathering phenomenon, but at this time, if the reflected sound is too large, the sound quality will feel too loud and rough. Therefore, for the above purpose, the present invention achieves the purpose of adjusting the level of the reflected sound by configuring the sound guide vane 10 to have a higher sound absorption coefficient than the sound reflection wall 20, thereby absorbing part of the original sound. According to the preferred structure of the present invention as described above, the present invention can expect to produce the best reverberation sound effect through the appropriate coordination between the absorption and reflection of the sound. In addition, in addition to the above structure, by further attaching or coating a material with a high sound absorption coefficient on the surface of the sound guide vane 10 to form a sound absorption finishing layer (omitted from the figure), the same effect can be obtained, so this method can also be implemented.

[0044] According to the preferred structure of the present invention as described above, the sound guide blade plate 10 can be implemented by a wooden material having a certain sound absorption performance, and can basically be implemented by a wooden column, or by attaching a wooden material to the surface of a column member of a different material such as a metal square tube. In addition, in the case of wood, although the sound absorption rate is about 5% to 10% depending on the frequency, and the sound absorption rate is basically not high, the more gaps there are inside the member, the higher the sound absorption rate. Therefore, the sound absorption rate (or sound absorption coefficient) can be appropriately adjusted by adjusting the space occupancy inside the wood member as needed.

[0045] At this time, in the case of the wooden column or wooden board as described above, since it is installed outdoors, it is more preferable to use wood that has been treated with antiseptic and has been deformed. In addition, in the present invention, in addition to the above-mentioned wooden material, the sound guide blade plate 10 can also be constructed in the following ways according to the choice of ordinary technicians in the field; for example, attaching, connecting, painting or spraying sound absorbing materials on the surface of a square tube made of metal material, or using components of different materials such as synthetic resin components, precast concrete components, or other construction methods such as concrete pouring, molding, etc.

[0046] On the other hand, Figure 1 As shown, according to the present invention, the sound guide blade plate 10 protrudes inward from the surface of the sound reflection wall 20 by a predetermined length (i.e., in the direction toward the center point CP on the plane), which is one of the structural features considered in the present invention in order to induce the sound gathering phenomenon of the main technical effect of the present invention. That is, when the sound is reflected from the surface of the sound reflection wall 20, in fact, a part of the sound is diffusely reflected from the surface of the sound reflection wall 20, resulting in the dispersion of the reflected sound, and it cannot fully return to the center direction of the stage. Therefore, the present invention is characterized in that when the sound guide blade plate 10 is installed as described above, by protruding from the surface of the sound reflection wall 20 toward the center direction of the stage by a predetermined length, the sound reflected from the sound reflection wall 20 can be concentrated and induced to the center direction (sound gathering effect). According to the technical features of the present invention, the sound guide blade plate 10 needs to protrude by a sufficient length to ensure that the sound gathering effect is obtained smoothly, and the protruding length is at least 8 cm or more, preferably 15 to 30 cm. However, when the protruding length of the sound guide vane plate 10 is less than 8 cm, it is difficult to expect the sound gathering effect, so it is not preferred. However, when the protruding length exceeds 30 cm, it can be adjusted to a certain extent within the range that does not hinder space design and construction.

[0047] Furthermore, if Figure 1 and Figure 2 As shown in the preferred embodiment shown in the figure, the sound space building of the present invention can also have a horizontal sound guiding blade plate 15 in addition to the vertical sound guiding blade plate 10 as described above. The horizontal sound guiding blade plate 15 has the same cross-sectional shape as the above-mentioned sound guiding blade plate 10 and is horizontally arranged parallel to the reference ground 100.

[0048] At this time, the horizontal sound guide blade plate 15 is also a main component that can more smoothly perform the sound gathering effect in the present invention. If the horizontal sound guide blade plate 15 is added, the upward propagation and dispersion of the sound can be effectively controlled, so the sound gathering effect of the present invention can be further enhanced. In addition, through the action of the horizontal sound guide blade plate 15 as described above, the reflected sound toward the upper direction can be induced to return to the center of the stage, so that the performer playing on the central sound source stage 50 can listen to his own performance while monitoring. The vertical position of this horizontal sound guide blade plate 15 is suitable for the height of the approximate center part of the total height of the sound guide blade plate 10, and the installation position can be changed according to the total height of the sound guide blade plate 10 and the sound reflection wall 20 and the distance from the center of the arc.

[0049] Next, the sound reflection wall 20 is a wall-type structure with a predetermined thickness. The sound reflection wall 20, such as Figure 1 and Figure 2 As shown, it is connected to the outer side of the sound guide blade plate 10 and is erected on the reference ground 100. Figure 1 As shown, the sound reflection wall 20 can be configured to have the same arc-shaped curved shape as the sound guide blade plate 10 when viewed from a plane. Therefore, the surface of the sound reflection wall 20 is perpendicular to the direction toward the arc center point CP, so that the sound incident from the arc center point CP in the central part can be reflected and returned to the original direction.

[0050] As described above, in the present invention, the sound reflection wall 20 is a structure that reflects sound and causes self-amplification of the sound through resonance, which is equivalent to a key component that plays the sound gathering role of the present invention together with the sound guide blade plate 10.

[0051] The sound reflection wall 20 as described above can be formed by a member having a smooth surface and high sound reflectivity, so that the incident sound can be reflected back as it is, wherein a glass panel is most suitable as the above-mentioned material. In addition, as the material of the sound reflection wall 20, metal panels such as aluminum, synthetic resin panels, marble with smooth surface treatment, smooth plain concrete and other materials can be used, and a combination of more than one of the above-mentioned materials can also be used, for example, a combination of a glass panel and an aluminum panel can also be used.

[0052] On the other hand, according to Figure 1 and Figure 2In the illustrated embodiment, although the sound guide blade plate 10 and the sound reflection wall 20 are combined, the sound reflection wall 20 is constructed as an integrated wall, and the inner side surface (i.e., the center direction of the arc) of the sound reflection wall 20 is attached and connected to the sound guide blade plate 10 as an additional component, in addition to the above-mentioned embodiment, the window frame can also be formed by the sound guide blade plate 10, and other glass panels can be inserted and fixed between the sound guide blade plates 10.

[0053] The sound guide blade plate 10 and the sound reflection wall 20 formed by combining as described above are as follows: Figure 1 and Figure 2 In the embodiment shown, a circular wall structure is formed as a whole, and a predetermined sound space 200 is formed as an atrium-type space portion inside the wall structure. In addition, as shown in the embodiment shown in the figure, a sound source stage portion 50 can be set in the central portion on the plane in the sound space 200. The sound generated during performances / music performances on the sound source stage portion 50 is amplified by the sound reflection and concentrated induction of the sound reflection wall 20 and the sound guide blade plate 10, thereby generating a sufficient volume for the audience sitting in the upper part of the roof auditorium 30 to enjoy without other audio equipment.

[0054] like Figure 1 and Figure 2 As shown, the roof auditorium 30 is a ceiling structure horizontally extending outward from the upper side of the sound reflection wall 20, and as shown in FIG. Figure 1 and Figure 2 The embodiment shown in the figure can be constructed so that an indoor space is formed in the lower part and used, and the upper part is formed into a roof shape, so that the audience can go up to watch the performances held in the sound space 200 where the sound source stage 50 is installed. According to the embodiment shown in the figure, although the roof auditorium 30 is horizontally installed at a height slightly lower than the uppermost end of the sound reflection wall 20, thereby maximizing the height of the sound reflection wall 20 and the sound guide blade plate 10, the roof auditorium 30 can also be installed at the uppermost height of the sound reflection wall 20, and safety facilities such as safety handrails (not shown) can be installed. In addition, according to Figure 2 , the rooftop auditorium 30 is shown to be in a horizontal form with the ground, but it can also be constructed in a slightly inclined form according to the specific implementation design.

[0055] Figure 3 and Figure 4 is a three-dimensional diagram of the overall shape of the sound space architectural structure of the present invention constructed as described above, as shown in FIG. Figure 3 and Figure 4As shown, the sound space architectural structure according to the present invention is constructed as a whole by arranging the architectural structure at a predetermined distance from the center of the arc, and forming an atrium-like space with a circular plane open at the top in the central part of the building plane. As described above, in the sound space architectural structure of the present invention, the surface forming the atrium space is composed of a wall structure composed of a combination of a plurality of sound-conducting blades and sound-reflecting walls, and a circular sound space open at the top is formed in the central part of the plane by the above-mentioned sound-conducting blades and sound-reflecting walls. In addition, Figure 3 and Figure 4 In the drawings, other reference numerals are omitted to avoid cluttering the drawings.

[0056] When constructing the sound space architectural structure of the present invention as described above, the distance from the center of the arc to the sound guide blade plate and the sound reflection wall, that is, the radius of the arc is preferably set in the range of about 15 to 35 meters. This is set based on the distance from the central sound source stage to the audience on the roof auditorium, the time difference of the sound returning to the center after hitting the sound reflection wall, and the distance for the resonance phenomenon to be smoothly generated through the coordination of the sound source and the reflected sound. From the above viewpoints, it is judged that the distance of 15 to 25 meters is most suitable for forming the best reverberation sound.

[0057] In addition, the height of the sound guide blade plate and the sound reflection wall structure can be determined in proportion to the distance from the center of the arc to the sound reflection wall, and can be set to a height of about 3 to 8 meters.

[0058] Next, the sound effect generated by the sound gathering phenomenon in the sound space architectural structure of the present invention as described above will be described in more detail with reference to the accompanying drawings. Figure 5 For a diagram illustrating the sound effects in the sound space architectural structure according to the present invention, refer to Figure 5 , the effects related to the sound effects of the present invention are explained.

[0059] As described above, in the present invention, a sound space 200 surrounded by a sound reflection wall 20 and a sound guide blade plate 10 is formed in the central part of the building plane. When outdoor activities such as music performances are performed in the sound space 200, the sound generated in the central stage part is self-amplified by the sound aggregation and resonance phenomenon caused by the structure of the sound guide blade plate 10 and the sound reflection wall 20. Therefore, in the absence of other amplifying equipment such as speakers or amplifiers, the audience on the top of the rooftop auditorium 30 can listen to the pure original sound at a satisfactory volume. This is the main technical feature of the present invention.

[0060] To explain in more detail, when a sound is produced by a performance or the like in the sound space 200 surrounded by the sound guide blade plate 10 and the sound reflection wall 20, the original sound S0 produced by the performance diffuses and hits the sound reflection wall 20 and then reflects, thereby producing a reflected sound S1. Figure 1As shown, since the sound reflection wall 20 is installed to form a circle on the center plane of the arc with the center point CP on the reference bottom surface 100 as the center point of the arc, the reflected sound S1 basically returns to the center direction of the stage where the original sound S0 occurs.

[0061] However, as described above, when the original sound S0 of the stage is reflected by the sound reflection wall 20, even if the sound reflection wall 20 is formed as a smooth surface suitable for reflecting sound, not all reflected sound S1 accurately returns to the center direction of the stage. In fact, scattered reflection occurs at a certain part of the surface of the sound reflection wall 20, resulting in dispersion of the reflected sound. In view of this problem, in the present invention, as described above, a sound guide vane plate 10 protruding to the inner side of the sound reflection wall 20 by a predetermined length is installed, so that the reflected sound S1 scattered and dispersed from the surface of the sound reflection wall 20 is induced by the sound guide vane plate 10 in the protruding direction, thereby controlling the dispersion of the reflected sound S1 and concentrating it to the center of the stage. This is a feature of the present invention (in the present invention, the effect of inducing the reflected sound to concentrate to the center as described above is named as a sound gathering effect).

[0062] By the sound gathering effect which is the main technical feature of the present invention, the reflected sound S1 concentratedly reflected to the center of the stage as described above meets the original sound S0 of the stage and the reflected sound returning from other directions, causing interference and resonance, and generating a resonance sound S2. This resonance sound S2 spreads to the upper part of the sound space 200 to reach the audience on the rooftop auditorium 30 extending to the upper outer side of the sound reflection wall 20, so that the audience can hear the sound. As a result, the audience on the rooftop auditorium 30 can directly hear the original sound S0 of the stage, and can also hear the resonance sound S2 and reverberation sound generated by the sound reflection and resonance effect inside the sound space 200, thereby having the effect of enjoying the performance with rich sound with three-dimensional sense, echo and aftersound like indoor performance.

[0063] Furthermore, according to the present invention as described above, unlike the existing outdoor performances in which the original sound of the stage is transmitted to the outside as it is, resulting in a large loss of volume and requiring other speakers, in the present invention, the original sound S0 of the stage is not directly diffused to the outside, but is reflected by the sound reflection wall 20 and generates a resonant sound S2 inside the predetermined sound space 200 and is then transmitted to the audience. Therefore, the lost sound energy can be greatly reduced. Moreover, according to the sound space architectural structure of the present invention, sufficient volume can be obtained without the need for audio equipment such as speakers, thereby having the advantage of enabling the audience to enjoy the pure original sound of the stage performance.

[0064] That is, Figure 2 and Figure 5As shown, according to the sound space architectural structure of the present invention, the sound space 200 surrounded by the sound reflection wall 20 is formed at a height lower than the roof auditorium 30 for the audience to watch. The sound space 200 of the present invention acts like a resonance tube (resonator) of a musical instrument, amplifying the original sound of the stage to a loud sound so that it can be heard by the roof auditorium 30 above. Therefore, when the central sound source stage 50 produces a performance sound, the performance sound is trapped in the sound space 200 and is not released immediately, but is reflected by the sound reflection wall 20 for many times, and is amplified to a loud sound through the interference and overlap of the sound, and then diffused to the upper part of the sound space 200 and transmitted to the audience on the roof auditorium 30. In addition, by continuously hearing the reverberation sound formed by repeated sound reflection, a clear three-dimensional sound without audio equipment can be heard in a pure original sound state.

[0065] On the other hand, regarding the reverberation sound as described above, generally, when the sound is reflected, the reverberation sound is composed of only the reflected sound and hardly absorbs the original sound, and the echo of the reverberation sound is very large and long, so that a phenomenon similar to an echo (cave effect) is generated. Therefore, in view of the above problem, the present invention provides a certain level of sound absorption function to the sound guide blade plate 10 connected to the sound reflection wall 20 that performs the above-mentioned sound reflection, thereby adjusting the sound absorption and reflection to produce the best reverberation sound, and this technology is proposed as a more preferred structure of the present invention.

[0066] That is, according to the preferred structure of the present invention as described above, the sound guide blade plate 10 is made of a material having a higher sound absorption rate than the sound reflection wall 20, or a sound absorption finishing material is attached (or coated) on its surface to form a sound absorption finishing layer, so that when the original sound S0 of the stage hits the sound reflection wall 20 and is reflected, a part of the sound is absorbed by the sound guide blade plate 10 and then returned. Through the sound absorption ability of the sound guide blade plate 10, the intensity of the reflected sound S1 can be appropriately adjusted, and the reverberation sound in the best state can be produced.

[0067] Therefore, according to the technical features of the present invention as described above, the following advantages are possessed; namely, when music performances and the like are performed in an open outdoor space, the sound generated on the central stage is amplified by itself through the phenomenon of sound aggregation and resonance, so that the audience can hear the pure original sound at a satisfactory volume without amplifying equipment such as speakers or amplifiers, and in terms of sound quality, the problem of dryness and weakness of sound in outdoor performances is overcome, so that the audience can enjoy a three-dimensional and rich performance like an indoor performance, and by achieving appropriate coordination between sound reflection, sound absorption and interference, appropriate echo and clear and transparent optimal reverberation can be produced.

[0068] The present invention has been described in detail above with reference to the described embodiments. However, it is natural that a person skilled in the art can make various substitutions, additions and replacements without departing from the scope of the described technical ideas. It should be understood that such modified embodiments also fall within the scope of protection of the present invention as determined by the scope of the claims.
