[0002] AREA OF TECHNOLOGY

[0003] The invention relates to equipment designed for the free positioning and fixation of acoustic electronic equipment in space, eliminating the impact of shocks and multi-frequency vibrations from the acoustic electronic equipment to the floor and vice versa. More specifically, it relates to devices for mounting electronic equipment, enabling the acoustic system to achieve unrivaled sound quality by positioning the speaker cones at the optimal point, with optimal direction toward the listening position, and with the optimal HF-MF axis tilt angle for the specific acoustic system. The claimed invention completely absorbs vibrational energy waves emanating from the surrounding environment, transmitted mechanically, and provides vibration isolation.The invention can be used for placing audio, video equipment, electronic equipment in seismically active areas and other electronic units, optical and mechanical devices sensitive to the negative influence of rhythmic vibrations and single shocks occurring in the environment.

[0004] PRIOR ART

[0005] Currently, tabletop stands and floor stands are manufactured only for small bookshelf speakers and studio monitors ranging from 237 mm to 1 m in height, in both active and passive formats. Various stands for mounting acoustic electronic equipment are available, with manufacturers using special designs to combat the negative impact of rhythmic vibrations and single shocks occurring in the surrounding environment. However, the claimed invention is unique.

[0006] DISCLOSURE OF THE INVENTION

[0007] The developer's goal was to create a stand that would completely block vibrations and resonances from the stand to the acoustic electronic equipment mounted on it, ensuring higher-quality sound reproduction. The technical result achieved in solving this problem is the ability to freely position the acoustic electronic equipment at a desired point in space using a three-dimensional coordinate system: x, y, and z. Another technical result is the ability to freely orient the acoustic electronic equipment suspended by the cables along three axes of rotation: around the x-axis (roll), around the y-axis (yaw), and around the z-axis (pitch), as well as lock it in a predetermined position.Another technical result is the elimination of physical contact between acoustic electronic equipment and any of the surfaces that make up the listening room's interior, thereby eliminating the possibility of mutual transmission of parasitic vibrations from both the room and seismic vibrations from the ground on which the building and the listening room are located. This technical result is achieved through the combination of all essential features.

The crossbar is provided with at least two adjustment units for securing the cables therein. The adjustment units are configured to adjust the cable length, the height of the suspended acoustic electronic equipment, and the angle of inclination. The cables are made of an elastic material and are connected to fastening units to prevent the acoustic electronic equipment from tipping over when it reaches an excessive angle relative to its center of gravity. The frame is also made of metal, wood, a polymer material, or combinations thereof. The support and the load-bearing crossbar are connected using adhesive, welded, or screwed connections, or combinations thereof. A support is also located in the base.The support is made of adjustable or non-adjustable legs and / or wheels with or without stoppers. The shrouds are made of ribbons, cords, cables, strands, ropes, and combinations thereof. The shrouds are also made of elastic material with a stretch coefficient of at least 3-5%. Furthermore, the support is telescopic, and the support is angled from 0° to 15° relative to the horizontal line.

[0011] THE BEST OPTION FOR IMPLEMENTING THE INVENTION

[0012] A cable-stayed support for acoustic electronic equipment according to the first embodiment consists of a frame. The frame includes a base 1 and a support 2 rigidly connected thereto. Base 1 is intended for placing support 2 and stops 3 on it. In a specific example of implementation, which does not limit the scope of legal protection, base 1 is made U-shaped (shown in Fig. 2). Also, base 1 accordingly can be made V-shaped (shown in Fig. 6), T-shaped (shown in Fig. 5), F-shaped, E-shaped, I-shaped, T-shaped and other shapes. Support 2 is a vertical structure rigidly connected on one side to base 1, and on the other side to at least one power crossbar 4. Support 2 in a specific example of implementation, which does not limit the scope of legal protection, is made telescopic.

[0013] The frame may be made of metal, wood, various types of polymer composite materials, and combinations thereof. In a specific embodiment, which does not limit the scope of legal protection, support 2 is inclined from 0° to 15° relative to the horizontal line. For the variant shown in Fig. 2, the angle of inclination of support 2 is 7°-8°. connections and combinations thereof. Power crossbar 4 is a U-shaped structure connected to support 2 in the middle section. In another embodiment, power crossbar 4 is a separate straight profile (shown in Fig. 5). Power crossbar 4 may also be made in a U-shape (shown in Fig. 6), a T-shape, an F-shape, an E-shape, an E-shape, a T-shape, and other shapes. In the lower part of the base 1, stops 3 are placed. Stops 3 can be made in the form of legs adjustable or non-adjustable in height, wheels with or without stoppers.The stops 3 may be mounted with a plastic end cap with a thick self-adhesive felt pad glued to it. This reduces resonances of the rack itself and minimizes the level of vibrations transmitted to the rack base 1 from the base on which it is installed. At least two adjustment units 5 are designed on the load-bearing crossbar 4 (shown in Fig. 5). In the best-case embodiment, at least four adjustment units 5 are designed on the load-bearing crossbar 4 (shown in Figs. 1, 2). In a specific embodiment, which does not limit the scope of legal protection, slot stoppers secured to the load-bearing crossbar 4 with screws are used as the adjustment unit 5. Cable stays 6 are fixed in the adjustment units 5. The adjustment units 5 are designed to adjust the length of the cable stays 6.By means of the adjustment units 5 the following is adjusted: the height of placement of the suspended acoustic electronic equipment 7 by synchronously changing the length of the front and rear cables 6 relative to the floor surface; the angle of inclination of the suspended acoustic electronic equipment 7 by changing the length of the front or rear cables 6 relative to the front of the acoustic electronic equipment 7 when fixing the cables 6 to the adjustment units 5. This makes it possible to correct the angle of inclination of the front of the acoustic electronic equipment 7 along the Oz axis (as shown in Fig. 3), and also in accordance with the axis of the HF-MF directivity pattern of the speakers of the acoustic electronic equipment 7. The cables 6 are intended for placement of the acoustic electronic equipment 7 on them. In this case, the acoustic electronic equipment 7 is placed on freely located cables 6 and is fixed with its upper corners in the fastening units 8.The fastening units 8 are intended to prevent the acoustic electronic equipment 7 from tipping over when the acoustic electronic equipment 7 is tilted forward or backward to an excessive angle relative to the center of mass. The shrouds 6 are made of an elastic material in the form of tapes, cords, cables, strands, ropes, and combinations thereof. One embodiment of the combined shroud 6 is made of an elastic cord connected to the elastic cord in the middle section by clamps (as shown in Fig. 4). Another embodiment of the combined shroud 6 is made in the form of an elastic cord consisting of latex threads covered on the outside with a polypropylene braid. In a specific embodiment, which does not limit the scope of legal protection, a rep cord with an elongation coefficient of 3-5% is used as the shroud 6. The shroud 6 is secured to adjustment units 5 opposite each other with the possibility of adjusting its length.To adjust the length of the cables 6, a micro winch or a lifting mechanism with a manual or electric drive can be used. In another embodiment, all adjustable components of the cable-stayed strut for the acoustic electronic equipment—wheeled stops 3, telescopic support 2, and adjustment units 5—are equipped with electric drives. To synchronize the operation of the electronic components, the cable-stayed strut is equipped with a control unit to automate the adjustment of the acoustic electronic equipment 7 in space. Control of the cable-stayed strut settings is also possible using specialized software installed on a smartphone, tablet, computer, or a separate software product for digitally optimizing indoor sound using measuring microphones for sound calibration.

[0014] A cable-stayed support for acoustic electronic equipment according to the second embodiment consists of a frame. The frame includes at least two bases 1 and is rigidly connected to at least two supports 2. Base 1 is intended to accommodate support 2 and stops 3. In a specific example of implementation, which does not limit the scope of legal protection, base 1 is made in an L-shape (shown in Fig. 1). Also, base 1 accordingly can be made in a U-shape, I-shape, T-shape, F-shape, E-shape, T-shape, T-shape and other shapes. Supports 2 represent a vertical structure rigidly connected on one side to base 1, and on the other side to at least one load-bearing crossbar 4. Support 2 in a specific example of implementation, which does not limit the scope of legal protection, is made telescopic. The frame can be made of metal, wood, various types of polymer composite materials and their combinations.The supports 2 are rigidly connected to the load-bearing crossbar 4 by means of adhesive, welded, screwed connections, and combinations thereof. The load-bearing crossbar 4 is a U-shaped structure connected to the supports 2 at the corners. The stops 3 are located in the lower part of the base 1. The stops 3 can be implemented in the form of legs, adjustable or non-adjustable in height, or wheels with or without stoppers. The stops 3 can be mounted with a plastic end cap with a thick self-adhesive felt pad glued to it. This ensures a reduction in resonance of both the rack itself and a minimization of the level of vibrations transmitted to the base 1 of the rack from the base on which it is installed. At least two adjustment units 5 are designed on the load-bearing crossbar 4. In the best example of implementation, at least four adjustment units 5 are designed on the load-bearing crossbar 4 (shown in Figs. 1, 2).In a specific example of implementation, which does not limit the scope of legal protection, slot stoppers secured to the power crossbar 4 with screws are used as the adjustment unit 5. Cables 6 are fixed in the fastening units 5. The adjustment units 5 are designed with the possibility of adjusting the length of the cables 6. With the help of the adjustment units 5, the angle of inclination of the suspended acoustic electronic equipment 7 is adjusted by changing the length of the front or rear cables 6 relative to the front of the acoustic electronic equipment 7 when the cables 6 are fixed to the adjustment units 5. This makes it possible to adjust the angle of inclination of the front of the acoustic electronic equipment 7 along the Oz axis (as shown in Fig. 3), and also in accordance with the axis of the HF-MF directivity pattern of the speakers of the acoustic electronic equipment 7. Cables 6 are intended for placing the acoustic electronic equipment 7 on them.In this case, the acoustic electronic equipment 7 is placed on freely located cables 6 and is fixed with its upper corners in fastening units 8. Fastening units 8 are intended to prevent the acoustic electronic equipment 7 from tipping over when the acoustic electronic equipment 7 reaches an excessive forward or backward tilt angle relative to the center of mass. The cables 6 are made of an elastic material in the form of tapes, cords, cables, strands, ropes and combinations thereof. One example of the design of the combined cable 6 is made of an elastic cord connected to the elastic cord in the middle part by clamps (as shown in Fig. 4). Another example of the design of the combined cable 6 is made in the form of an elastic cord consisting of latex threads covered on the outside with a polypropylene braid. In a specific example of the design, which does not limit the scope of legal protection, a rep cord with an elongation coefficient of 3-5% is used as the cable 6.The stay cable 6 is secured to opposing fastening units 5 with adjustable length. In this specific embodiment, a micro winch or a lifting mechanism with a manual or electric drive is used to adjust the length of the stay cable 6. In another embodiment, all adjustable components of the stay cable strut for the acoustic electronic equipment—wheeled stops 3, telescopic support 2, and adjustment units 5—are equipped with electric drives. To synchronize the operation of the electronic components, the stay cable strut is equipped with a control unit for automating the spatial adjustment of the acoustic electronic equipment 7. The stay cable strut settings can also be controlled using specialized software installed on a smartphone, tablet, computer, or a separate software product for digital sound optimization in the KDP using measuring microphones for sound calibration.

[0015] A cable-stayed support for acoustic electronic equipment is assembled as follows. A frame is formed from a base 1, a support 2, and a load-bearing crossbar 4, or from at least two bases 1, at least two supports 2, and a load-bearing crossbar 4. If stops 3 are present, they are secured to the lower part of the base 1. At least four fastening units 5 are installed on the load-bearing crossbar 4. Cables 6 are fixed into the adjusting units 5. Vibration energy transmitted mechanically from the environment is absorbed by cables 5. Vibration isolation is provided by the inertial force of the electronic equipment freely suspended on cables 5 and the shock-absorbing effect of the stretch coefficient of cables 5.According to the existing rules for placing an acoustic system, the acoustic electronic equipment 7 should: be installed along the long wall of the room; the stereo speakers and the listener should be located at the corners of an equilateral triangle; the fronts of the acoustic systems (acoustic axes) should be oriented directly towards the listening position; the height of the HF emitters of bookshelf speakers, or the axis between the HF and MF drivers of a floor-standing speaker should be at the ear level of a seated person; do not place the acoustic electronic equipment 7 close to the rear wall behind the speakers; do not place the acoustic electronic equipment 7 close to the side walls; the listener should not be located close to the wall behind him. Some of the above conditions are difficult to fulfill solely due to the physical parameters of the system: acoustic speakers, room, listening position. For example, according to I.4 it is often impossible to fulfill due to the height of the chair at the listening position and the height of the speaker.At the same time, there are other physical parameters that fundamentally affect the quality of sound reproduction, which manufacturers do not even think about.The claimed invention allows for the compliance with the said rules and additionally allows for: free positioning and fixation at any point in the space (volume) of the room, taking into account vertical axial modes across the width and length of the room; free positioning and fixation at any height in the space (volume) of the room, taking into account horizontal acoustic modes in the room; free positioning and fixation with its front in the direction of the listening point; free positioning and fixation by the angle of inclination of the HF-MF emitter axis from positive to negative values ​​relative to the listening point; not having a direct physical connection with the floor to eliminate the transmission of parasitic resonances from the speaker to the floor of the room, as well as in the opposite direction, from the floor to the acoustic electronic equipment 7.A cable-stayed stand for acoustic electronic equipment will allow any speaker to realize its potential even beyond what it would otherwise achieve in normal operation without a cable-stayed stand. INDUSTRIAL APPLICABILITY.

[0016] The cable-stayed stand for the acoustic electronic equipment 7 ensures: free positioning and fixation of the acoustic electronic equipment 7 at any point in the space (volume) of the listening room along the x, y, z axes, taking into account the vertical axial modes along the width and length of the room; free positioning and fixation of the acoustic electronic equipment 7 at any height in the space (volume), taking into account the horizontal acoustic modes in the room; free positioning and fixation of the front of the acoustic electronic equipment 7 along the Ox, Oy, Oz axes,in the direction of the listening point; free positioning and fixation of the acoustic electronic equipment 7 according to the angle of inclination of the HF-MF emitter axis from positive to negative values ​​relative to the listening point; elimination of direct mechanical connection of the acoustic electronic equipment 7 with the floor of the room in order to eliminate the possibility of transmitting parasitic resonances from the speakers of the acoustic electronic equipment 7 to the floor of the room, as well as in the opposite direction, from the ground into the body of the acoustic electronic system, and from there into the speaker baskets of the acoustic electronic equipment 7; elimination of the propagation of shocks and multi-frequency vibrations from the acoustic electronic equipment 7 placed onto the floor of the room,In which a cable-stayed stand for acoustic electronic equipment 7 is located, and also to eliminate the impact of shocks and multi-frequency vibrations in the opposite direction—from the floor to the acoustic electronic equipment 7. For high-end acoustic systems, it is time to revise the technology of placement on the room floor to a technology of positioning the acoustic system within the space (volume) of the room. To achieve this, the speaker of the acoustic system must be integrated into the declared cable-stayed stand for acoustic systems. In the mobile version, the base of the frame has free-swivel locking wheels, which allows the cable-stayed stand for the acoustic system to move freely and fix the front of the speaker in the desired location in the room.and the direction of the speaker's front to the listening position. Which has a mechanism for adjusting the height of the cable-stayed column with the speaker and fixing the speaker above the floor at a specified height. Which allows for adjusting the tilt angle of the (suspended) speaker either by tilting the swinging frame of the elastic cables with the speaker, or by changing the length of the front or rear elastic cables (relative to the speaker's front) when fixing the cables to the fastening points directly on the cable-stayed column frame for the acoustic system. Which allows for intelligent adjustment of the suspended speaker's mass in accordance with the calculated speaker mass coefficient. In which the speaker being placed has no direct physical contact with the room floor, as it is freely suspended on elastic cables fixed by fastening points on the cable-stayed column frame for the acoustic system with elastic damping feet or wheels. Which,Depending on the owner's needs, the cable-stayed stand can accommodate an acoustic system consisting of not just a single speaker, but a speaker array of any configuration: a high-frequency tweeter, a midrange speaker, a bookshelf speaker, a floorstanding speaker, a woofer, or a subwoofer. A cable-stayed frame design is also available, either permanently fixed to the ceiling or sliding along guides. A cable-stayed stand allows any speaker to realize its full potential, even to a greater extent than it would otherwise achieve during normal operation without a cable-stayed stand.
