Description

Technical Field

[0001] The invention belongs to the field of sound absorbing body structures, and in particular relates to a multi-curved sound absorbing body. Background Art

[0002] As the economy continues to develop, people's pursuit of quality of life and professional entertainment is gradually increasing. Professional facilities such as various theaters, stadiums, dance halls, and professional rooms such as acoustic recording studios and studios have corresponding requirements for acoustic technical indicators. In addition, the demand for creating a music appreciation environment in family homes is also gradually increasing.

[0003] The traditional sound absorbing structure only uses the lower surface to absorb or diffuse sound, which has limited sound absorption and diffusion effects and is a waste of space. At the same time, the installation of the traditional sound absorbing body is relatively difficult, especially when it comes to large-sized ceiling-type sound absorbing bodies. Summary of the invention

[0004] The purpose of the present invention is to overcome the technical problems existing in the above-mentioned background technology and provide a multi-curved sound absorbing body.

[0005] In order to achieve the above technical purpose, the present invention adopts the following technical solution:

[0006] A multi-curved sound absorbing body comprises a bracket part and a sound absorbing panel assembly. The bracket part comprises a pair of longitudinal frame panels, and a single or two longitudinal frame panels of the bracket part are arranged in a curved surface structure or a non-smooth undulating structure or a smooth undulating structure in the width direction and / or the height direction; the sound absorbing panel assembly is arranged on the lower surface of the bracket part or on the lower surface and the upper surface of the bracket part, and the sound absorbing panel assembly is a common sound absorbing structure such as a slit sound absorbing panel or a perforated sound absorbing panel.

[0007] The sound absorbing panel assembly is in a curved structure, a non-smooth undulating structure, or a smooth undulating structure in the height direction, and the sound absorbing panel assembly is directly or indirectly fixed to the frame panel in the length direction.

[0008] When the sound-absorbing panel assembly is arranged in a curved surface, it can produce a sound diffusion effect while absorbing sound. The bracket part is the fixed base of the sound-absorbing panel assembly. At the same time, the length direction frame plate is in a curved structure or a non-smooth undulating structure or a smooth undulating structure in the width direction and / or the height direction, which can produce a sound diffusion effect, thereby increasing the overall sound diffusion effect of the multi-curved sound-absorbing body. In particular, when multiple multi-curved sound-absorbing bodies are arranged in a staggered manner in the height direction, the sound diffusion effect of the length direction frame plate is more significant. The non-smooth undulating structure includes common shapes such as a broken line shape and a sawtooth shape, and the smooth undulating structure is a wave shape of various shapes. In specific use, the bracket part is used as the installation base of the multi-curved sound-absorbing body, such as connecting the bracket part through a hanger to hang the entire multi-curved sound-absorbing body, or connecting the bracket part through an installation clip to fix the entire multi-curved sound-absorbing body to the wall.

[0009] Common sound diffusion shapes include wavy, flat-head serrated, pointed-head serrated, round-head serrated, etc. According to the needs of the sound diffusion size, when the size of the frame plate in the length direction is large enough, a non-smooth undulating structure or a smooth undulating structure is used; when the size of the frame plate in the length direction is small, a curved surface structure is used.

[0010] When the sound absorbing panel assembly is arranged on the lower surface and the upper surface of the bracket part, the sound absorbing panel assembly on the lower surface of the bracket part and the sound absorbing panel assembly on the upper surface of the bracket part can be connected as one. In this case, the bracket part only includes a pair of frame panels in the length direction, and does not have a frame in the width direction. The sound absorbing panel assembly of the above shape has a simple appearance, can be hung horizontally or vertically, and has high installation flexibility.

[0011] In a specific implementation, preferably, the bracket portion also includes a pair of width-direction frame plates, the length-direction frame plates and the width-direction frame plates are connected to each other, the width-direction frame plates are in an arc structure or a non-smooth undulating structure or a smooth undulating structure in the length direction and / or the height direction, and the sound-absorbing panel assembly is directly or indirectly fixed to the length-direction frame plates or the width-direction frame plates.

[0012] The width-direction frame plate has a curved structure or a non-smooth undulating structure or a smooth undulating structure in the length direction and / or height direction, which can produce a sound diffusion effect, further increasing the overall sound diffusion effect of the multi-curved sound absorbing body.

[0013] According to the requirements of the sound diffusion size, when the size of the frame plate in the width direction is large enough, a non-smooth undulating structure or a smooth undulating structure is adopted; when the size of the frame plate in the width direction is small, a curved surface structure is adopted.

[0014] As an improvement of the multi-curved sound absorbing body of the present invention, the frame plate in the length direction is a perforated sound absorbing plate structure.

[0015] The frame plate in the length direction is a perforated sound-absorbing plate structure, so that the frame plate in the length direction has not only a sound diffusion effect but also a sound absorption effect; at the same time, the sound absorption performance of the frame plate in the length direction can be conveniently adjusted by selecting raw materials with different perforation rates.

[0016] As an improvement of the multi-curved sound absorbing body of the present invention, the frame plate in the length direction and / or the frame plate in the width direction is a perforated sound absorbing plate structure.

[0017] The length direction frame plate and / or the width direction frame plate is a perforated sound-absorbing panel structure, so that the length direction frame plate and / or the width direction frame plate has a sound absorption effect in addition to the sound diffusion effect; at the same time, by selecting raw materials with different perforation rates, the sound absorption performance of the length direction frame plate and / or the width direction frame plate can be conveniently adjusted.

[0018] In a specific implementation, the sound absorbing panel assembly is optionally arranged on the lower surface of the bracket part, and a back cover plate is arranged on the upper surface of the bracket part, and the back cover plate is a solid panel or a perforated sound absorbing panel. In implementation, a solid panel or a perforated sound absorbing panel is selected as the back cover plate according to the sound absorption performance requirements.

[0019] As an improvement of the multi-curved sound absorbing body of the present invention, the back cover plate is in a curved structure or a non-smooth undulating structure or a smooth undulating structure in the height direction, so that the back cover plate also has a sound diffusion effect.

[0020] As a preferred embodiment of the multi-curved sound absorbing body of the present invention, the sound absorbing panel assembly is a slit sound absorbing panel structure, the sound absorbing panel assembly includes a plurality of slats, the bracket part includes a main structure keel, the plurality of slats are fixed on the main structure keel, the main structure keel is the structural basis of the bracket part, and the length direction frame panel and / or the width direction frame panel are connected to the main structure keel.

[0021] The sound-absorbing panel assembly is a slit sound-absorbing panel structure composed of multiple slats. The slit sound-absorbing panel structure has superior appearance and performance and is also easy to install.

[0022] The slats are connected to the main structure keel by existing commonly used means. The slats can be directly connected to the main structure keel by rivets or the like, or the main structure keel is provided with a bayonet for fixing the slats, and the slats are directly clamped on the main structure keel. By adding the main structure keel to the bracket part, the overall structural strength of the multi-curved sound absorbing body can be improved. And by increasing the length of the main structure keel or increasing the number of the main structure keels, a large-sized multi-curved sound absorbing body can be realized. The larger the size of the multi-curved sound absorbing body, the larger the size of the curved surface thereon, and the lower the lower limit sound frequency that can be diffused.

[0023] As an improvement of the multi-curved sound absorbing body of the present invention, the sound absorbing panel assembly further comprises a plurality of slat keels, a plurality of slats are fixed on the slat keels, and the slat keels are connected to the main structure keels.

[0024] The slats are fixed to the main structure keel through the slat keel, which reduces the complexity of installation. In practice, the entire sound absorbing panel assembly can be divided into a plurality of slatted sound absorbing panel modules consisting of slats and slatted keels, and then the slatted sound absorbing panel modules are installed on the main structure keel.

[0025] In a specific implementation, optionally, the slat includes a plate body and a fixed leg arranged on the back of the plate body, the fixed leg is a single fixed leg, a double fixed leg or a triple fixed leg, the surface of the plate body is a plane, an arc-shaped arch surface, an arc-shaped concave surface, a corrugated surface, a convex edge surface or a concave edge surface; the cross-sectional shape of the plate body is a rectangle, trapezoid, T-shape, E-shape, Π-shape, bow-shape, C-shape, D-shape, B-shape, circle, triangle or ellipse.

[0026] Optionally, in a specific implementation, a sound absorbing member is provided in the multi-curved sound absorbing body, and the sound absorbing member is a common sound absorbing material such as sound absorbing cotton.

[0044] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] like Figure 1-3 As shown, a multi-curved sound-absorbing body includes a bracket part 1 and a sound-absorbing panel assembly 2. The bracket part 1 includes a pair of longitudinal frame panels 11, and the two longitudinal frame panels 11 of the bracket part 1 are arranged in an arc surface structure in the width direction and the height direction; the sound-absorbing panel assembly 2 is arranged on the lower surface and the upper surface of the bracket part 1, and the sound-absorbing panel assembly 2 is a slit sound-absorbing panel sound-absorbing structure, and the sound-absorbing panel assembly 2 on the lower surface of the bracket part 1 and the sound-absorbing panel assembly 2 on the upper surface of the bracket part 1 can be connected as a whole. At this time, the bracket part 1 only includes a pair of longitudinal frame panels 11, and does not have a frame in the width direction. The sound-absorbing panel assembly 2 of the above-mentioned shape has a simple appearance, can be suspended horizontally or vertically, and has high installation flexibility.

[0047] When the length direction frame plate 11 is small in size, a curved surface structure is adopted. The sound absorbing panel assembly 2 is a curved surface structure in the height direction, and the sound absorbing panel assembly 2 is directly fixed on the main structure keel 3 and indirectly fixed on the length direction frame plate 11. The length direction frame plate 11 is connected to the main structure keel 3.

[0048] The longitudinal frame plate 11 is a perforated sound-absorbing plate structure, so that the longitudinal frame plate 11 has a sound-absorbing effect in addition to the sound diffusion effect; at the same time, the sound absorption performance of the longitudinal frame plate 11 can be conveniently adjusted by selecting raw materials with different perforation rates.

[0049] When the sound absorbing panel assembly 2 is arranged in a curved surface, it can produce a sound diffusion effect while absorbing sound. The bracket part 1 is a fixed base for the sound absorbing panel assembly 2. At the same time, the length direction frame plate 11 is an arc surface structure in the width direction and the height direction to produce a sound diffusion effect, thereby increasing the overall sound diffusion effect of the multi-curved sound absorbing body 100. In particular, when multiple multi-curved sound absorbing bodies 100 are arranged in a staggered manner in the height direction, the sound diffusion effect of the length direction frame plate 11 is more significant.

[0050] When in use, the bracket part 1 is used as an installation base for the multi-curved sound absorbing body 100 , for example, the bracket part 1 is connected with a hanging piece to hang the entire multi-curved sound absorbing body 100 .

[0051] Embodiment 2:

[0052] like Figure 4 The difference between Example 2 and Example 1 is that the sound absorbing panel assembly 2 has a non-smooth undulating structure in the height direction, and the two longitudinal frame panels 11 have a smooth undulating structure in the width direction. The above structure is set as a common sound diffusion curved surface. The longitudinal frame panel 11 is large enough, and a non-smooth undulating structure is selected.

[0053] Embodiment 3:

[0054] like Figure 5-6 As shown, the difference between Example 3 and Example 1 is that the sound absorbing panel assembly 2 is a wave-shaped smooth undulating structure in the height direction, and the two longitudinal frame panels 11 are arranged in a smooth undulating structure in the width direction. The above structure is beautiful in appearance and is a common sound diffusion curved surface.

[0055] Embodiment 4:

[0056] like Figure 7-11As shown, a multi-curved sound absorbing body comprises a bracket part 1 and a sound absorbing panel assembly 2. The bracket part 1 comprises a pair of parallel longitudinal frame panels 11 and a pair of widthwise frame panels 12, and the longitudinal frame panels 11 and the widthwise frame panels 12 are connected to each other. The two longitudinal frame panels 11 are arranged in a smooth undulating structure in the width direction, and the two widthwise frame panels 12 are arranged in a curved surface structure in the longitudinal direction. Both the longitudinal frame panels 11 and the widthwise frame panels 12 can produce a sound diffusion effect, further increasing the overall sound diffusion effect of the multi-curved sound absorbing body 100.

[0057] The length direction frame plate 11 and the width direction frame plate 12 are perforated sound-absorbing plate structures, so that the length direction frame plate 11 and the width direction frame plate 12 have not only the sound diffusion effect, but also the sound absorption effect; at the same time, by selecting raw materials with different perforation rates, the sound absorption performance of the length direction frame plate 11 and the width direction frame plate 12 can be conveniently adjusted.

[0058] The sound absorbing panel assembly 2 is connected to the lower surface of the bracket part 1, and the bracket part 1 includes a main structure keel 3, and the sound absorbing panel assembly 2 is directly fixed on the main structure keel 3. Fig.11 As shown, the sound absorbing panel assembly 2 includes a plurality of slats 20, and the slats 20 are directly snapped onto the main structure keel 3. The sound absorbing panel assembly 2 is a slit sound absorbing panel structure composed of a plurality of slats 20, which has a superior appearance and performance and is also easy to install. The main structure keel 3 is the structural basis of the bracket part 1, and the longitudinal frame plate 11 is connected to the main structure keel 3. By adding the main structure keel 3 to the bracket part 1, the overall structural strength of the multi-curved sound absorbing body 100 can be improved. And by increasing the length of the main structure keel 3 or increasing the number of the main structure keels 3, a large-sized multi-curved sound absorbing body 100 can be realized. The larger the size of the multi-curved sound absorbing body 100, the larger the size of the curved surface thereon, and the lower the lower limit sound frequency that can be diffused.

[0059] The sound absorbing panel assembly 2 has a smooth undulating structure in the height direction, and has both sound absorption and diffusion effects. A back sealing plate 5 is nailed or riveted to the upper surface of the bracket part 1, and the back sealing plate 5 is a perforated sound absorbing plate. The back sealing plate has a smooth undulating structure in the height direction, so that the back sealing plate also has sound diffusion and sound absorption effects.

[0060] The multi-curved sound absorbing body 100 is provided with a sound absorbing member (not shown), and the sound absorbing member is a common sound absorbing material such as sound absorbing cotton.

[0061] The frame plates 11 in the length direction are arranged in parallel, so as to facilitate the side-by-side installation of the multi-curved sound absorbing bodies 100 in the width direction.

[0062] Embodiment 5:

[0063] like Fig.12 As shown, the difference between Example 5 and Example 4 is that the sound absorbing panel assembly 2 further includes a plurality of slat keels 4, a plurality of slats 20 are fixed on the slat keels 4, and the slat keels 4 are connected to the main structure keels 3.

[0064] In order to fix the slats 20 on the main structure keel 3, a slat keel 4 with a bent shape similar to that in the patent document with publication number CN207244882U is used. The slat keel 4 with a bent shape matching the curve of the main structure keel 3 is fixed on the main structure keel 3, and the slats 20 are fixed to the slat keel 4 with a bent shape. The slats 20 are fixed to the main structure keel 3 through the slat keel 4, which reduces the complexity of installation. In practice, the entire sound absorbing panel assembly 2 can be divided into a plurality of slat sound absorbing panel modules composed of the slats 20 and the slat keels 4, and then the slat sound absorbing panel modules are installed on the main structure keel 3.

[0065] Embodiment 6:

[0066] like Figure 13-15 As shown, the difference between Example 6 and Example 4 is that a pair of longitudinal frame plates 11 are symmetrically arranged.

[0067] The words "first", "second" and similar words used in the specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantitative limitation, but rather indicate the presence of at least one. Words such as "include" or "comprise" and similar words mean that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, and do not exclude other elements or objects. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0068] The embodiment is only a single implementation method of the present invention. For ordinary technicians in this field, other embodiments can be obtained according to the drawings without creative work, which are also within the protection scope of the present invention.
