Description

[0001] Cable-stayed acoustic system.

[0002] FIELD OF TECHNOLOGY.

[0003] The invention relates to equipment designed for free positioning and fixing components of an acoustic system in space with control and synchronization of the phases of signals from the components' emitters, eliminating the impact of shocks and multi-frequency vibrations from the acoustic system to the floor and vice versa.More specifically, the invention relates to the field of acoustics and can be used in the manufacture of high-quality acoustic electronic equipment that makes it possible to achieve unrivaled sound quality from an acoustic system: by positioning the diffusers of each component of the acoustic system at the optimal point in the listening room, with optimal direction to the listening point, optimal phasing of the emitters of each component in the time domain, with an optimal angle of inclination of the axis of each emitter, due to the free choice of the number of components, their sizes in the acoustic system kit and, depending on this indicator, a free number of sound reproduction bands.

[0004] The claimed invention has no analogues.

[0005] DISCLOSURE OF THE INVENTION

[0006] The developer's goal was to create a new acoustic system that completely blocks vibrations and resonances from reaching each component, ensuring higher-quality sound reproduction. The technical result achieved by solving this problem is the ability to freely position each component of the acoustic system at the desired point in the listening room using a three-dimensional coordinate system: x, y, and z, and lock it in a given position, taking into account the phase of the reproduced signal. The technical result also allows for the free orientation of each component of the cable-stayed acoustic system, suspended by cables, in accordance with three axes of rotation: around the x-axis (roll), around the y-axis (yaw), and around the z-axis (pitch), and locking it in a given position.Another technical result is the elimination of physical contact between the acoustic system components and any of the surfaces that make up the listening room's interior, thereby eliminating the possibility of mutual transmission of both parasitic vibrations from 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.

[0007] The invention consists of a cable-stayed acoustic system consisting of a frame comprising a base and a support rigidly connected thereto. At least two load-bearing crossbars with rods are adjustablely secured to the support. At least two adjustment assemblies for securing the cables are designed on the rod. The adjustment assemblies are configured to adjust the cable length, the height of the acoustic system components, the angle of inclination of the suspended acoustic system components, and the component front extension length. Furthermore, the acoustic system components are provided with fasteners for securing the cables. Furthermore, the support is serrated on one side along its entire length. The support is also telescopic. Furthermore, the frame is made of metal, wood, a polymer material, or combinations thereof. The support is angled from 0° to 15° relative to the vertical.The acoustic system components include a super-tweeter module, a high-frequency driver module, a high-range midrange driver module, a low-range midrange driver module, a mid-bass driver module, and a bass driver module. The cables are made of ribbons, cords, cables, strands, and ropes, or combinations thereof. The cables are also made of elastic material with a stretch coefficient of at least 3-5%. The boom is adjustable in length.

[0010] THE BEST OPTION FOR IMPLEMENTING THE INVENTION

[0011] The cable-stayed acoustic system consists of a frame. The frame includes a base 1 and a support 2 rigidly connected to it. Base 1 is designed to accommodate the acoustic system on a horizontal surface and to secure support 2 to it. In a specific embodiment that does not limit the scope of legal protection, base 1 is U-shaped. Base 1 may also be V-shaped, T-shaped, or of other shapes. Support 2 is a vertical structure rigidly connected to base 1 on one side. In a specific embodiment that does not limit the scope of legal protection, support 2 has a serrated edge 5 along one side along its entire length. In one embodiment that does not limit the scope of legal protection, support 2 may be telescopic. The frame may be made of metal, wood, various types of polymer composite materials, and combinations thereof.In one embodiment that does not limit the scope of legal protection, support 2 is inclined from 0° to 15° relative to the vertical. At least two power crossbars 3 with rods 11 are adjustablely secured to support 2. The distance between rods 11 is variable and depends on the dimensions of component 8. Rod 11 of power crossbar 3, in a specific embodiment that does not limit the scope of legal protection, has a fixed telescopic structure adjustable in length, making it possible to adjust the position of the front of component 8 along the reach along the horizontal axis, relative to the other components 8 in the cable-stayed acoustic system for the purpose of precise signal phase adjustment. Power crossbar 3 with rod 11 is a U-shaped structure connected in the middle part to support 2 by means of a fastening unit 4.Also, the power bridge 3 may be respectively made in a U-shape, a T-shape, an F-shape, an E-shape, a T-shape, a T-shape, and other shapes. The fastening unit 4 is rigidly connected to the power bridge 3. By means of the fastening unit 4, the height of the placement of the power bridge 3, and, consequently, the components 8 of the cable-stayed acoustic system, is adjusted. The inner part of the fastening unit 4 may be toothed, as on the edge 5. The fastening unit 4 is designed with the possibility of rigidly fixing the power bridge 3 on the support 2 at the required height, for example, by engaging its teeth with the teeth of the edge 5. In other embodiments, not limiting the scope of legal protection, the technical solution for fixing the bridge 3 may be holes for installing pins, as on exercise machines, self-locking clamps, or eccentric clamps. In the lower part of the base 1, additional stops are placed.The supports can be height-adjustable or non-adjustable feet, or wheels with or without stoppers. The supports can be mounted with a plastic end cap with a thick, self-adhesive felt pad. This reduces resonance within the speaker system itself and minimizes vibrations transmitted to the base 1 from the horizontal surface on which it is mounted. At least two adjustment units 6 are secured to the rod 11 of the power crossbar 3. In the best example of execution, at least four adjustment units 6 are secured to the rod 11 of the power crossbar 3. In a specific example of execution, which does not limit the scope of legal protection, slot stoppers on a bracket with a lock are used as the adjustment unit 6, freely sliding along the rod 11 of the power crossbar 3. Cable stays 7 are secured in the adjustment units 6. The adjustment units 6 are designed with the possibility of adjusting the length of the cable stays 7.By means of the fastening unit 4, the height of placement of the components 8 of the acoustic system is adjusted. By means of the adjustment units 6, the following is adjusted: the height of placement of the components 8 of the acoustic system by synchronously changing the length of the front and rear cables 7 relative to the floor surface; the angle of inclination of the suspended components 8 of the acoustic system by changing the length of the front or rear cables 7 relative to the front of the components 8 when fixing the cables 7 to the adjustment units 6; the time calibration of the phase of the emitted signal due to the extension of the front of the component 8 relative to the other components 8 in the cable-stayed acoustic system by moving and fixing the adjustment units 6 on the rods 11 of the crossbar 3 in order to maintain the same distance from the front of each component 8 to the listening point 10, regardless of the height of placement of the component 8 relative to the listening point 10.This makes it possible to adjust the position of each of the fronts of the mutually independent components 8 of the cable-stayed acoustic system in the three-dimensional coordinate system x, y and z of the listening room, along the axes Ox (roll), Oy (yaw), Oz (pitch) (as shown in Fig. 13), and also in accordance with the axis of the directivity pattern of each emitter of the component 8 of the cable-stayed acoustic system. The cables 7 are intended for placing the components 8 of the cable-stayed acoustic system on them. In this case, the components 8 of the cable-stayed acoustic system are made with fasteners 9 for fixing the cables 7. The fasteners 9 can be located at any points of the component 8 body: two at the top for suspension; at the bottom for fixing the position of the cord passing under the component 8 with the component 8 lying on the cords; and other points of the body.The components 8 in the described variants of the speaker set of different formats that do not limit the scope of legal protection are: a supertweeter module, a high-frequency speaker module, a high-range midrange speaker module, a low-range midrange speaker module, a mid-bass speaker module, and a bass speaker module. The shrouds 7 are made of elastic material in the form of ribbons, cords, cables, strands, ropes, and combinations thereof. In one embodiment, the combined shroud 7 is made of an elastic cord in the middle part connected to the elastic cord by clamps. In another embodiment, the combined shroud 7 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 that does not limit the scope of legal protection, a rep cord with an elongation coefficient of 3-5% is used as the shroud 7. The shroud 7 is secured in the adjustment unit 6, and on the other side in the fastener 9.To adjust the length of cables 7, 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 acoustic system—wheel stops, telescopic support 2, adjustment units 6, and fastening units 4—are equipped with electric drives. To synchronize the operation of the electronic components, the cable-stayed acoustic system is equipped with a control unit to automate the adjustment of the components 8 in space. Control of the cable-stayed acoustic system settings is also possible using specialized software installed on a smartphone, tablet, computer, or a separate software product for digitally optimizing indoor sound using microphones for sound calibration.For example, with the Dirac Live acoustic correction system, you can easily measure the acoustic characteristics of your speakers and room and calibrate your sound system to ensure it reproduces sound as intended. The advantage of a cable-stayed acoustic system is the free positioning of each component, even within coordinates calculated using digital room acoustic correction software.

[0012] The cable-stayed acoustic system is assembled as follows. A frame is formed from a base 1 and a support 2. The required number of power crossbars 3 with rods 11 are fixed to the support 2. If stops are present, they are fixed to the lower part of the base 1. At least four adjustment units 6 are installed on rods 11 of the power crossbar 3. Cables 7 are fixed in the adjustment units 6. The vibration energy transmitted mechanically from the environment is absorbed by the cables 7. Vibration isolation is provided by the inertial force of the components 8 of the acoustic system freely suspended on the cables 7 and the shock-absorbing effect of the stretch coefficient of the cables 7. According to the existing rules for arranging an acoustic system, traditional speakers should: 1.) be installed along the long wall of the room; 2.) stereo speakers and the listener should be located at the corners of an equilateral triangle; 3.) the fronts of the acoustic systems (acoustic axes) should be oriented directly towards the listening position;4.) the height of the high-frequency emitters of bookshelf speakers, or the axis between the high-frequency and mid-range speakers of a floor-standing speaker should be at the level of the ear of a sitting person; 5.) do not place the speakers of the acoustic system close to the rear wall behind the speakers; 6.) do not place the speakers of the acoustic system close to the side walls;7.) the listener should not be located close to the wall behind him. Some of the above conditions are difficult to fulfill only due to the physical parameters of the system: acoustic speakers, the room, the listening position 10. 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 HF-MF emitters of the speaker. At the same time, there are other physical parameters that fundamentally affect the quality of sound reproduction, which even the manufacturers of acoustic systems do not consider. The claimed invention makes it possible to ensure the implementation of the specified rules separately for each of the components 8 of the cable-stayed acoustic system, and also additionally allows it to: be freely positioned and fixed at any point in the space (volume) of the room, taking into account the vertical axial modes along the width and length of the room;freely positioned and fixed at any height of the space (volume) of the room, taking into account the horizontal acoustic modes in the room; freely positioned and fixed with its front in the direction of the listening point 10; freely positioned and fixed the axis of the emitter of each component 8 of the cable-stayed acoustic system by the angle of inclination from positive to negative values ​​relative to the listening point 10; freely adjusted along the horizontal axis and fixed the position of the front of component 8 by reach, relative to the other components 8 in the cable-stayed acoustic system for the purpose of fine-tuning the phase of the signal at the listening point 10 by moving and fixing the adjustment units 6 along the rods 11 of the power jumper 3 to maintain the same distance from the front of each component 8 to the listening point 10 regardless of the height of the placement of component 8 relative to the listening point 10;Have no direct physical connection to the floor to prevent the transmission of parasitic resonances between the components of the 8-cable acoustic system, from any of the 8 components to the room floor, and from the floor to the components of the 8-cable acoustic system. The cable-cable acoustic system will allow each component to realize its potential to an even greater extent than any of the speakers can achieve when used as part of a conventional floor-standing speaker.

[0013] INDUSTRIAL APPLICABILITY

[0014] The cable-stayed acoustic system ensures: free positioning and fixation of each of the components 8 of the acoustic system 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 components 8 of the acoustic system at any height of the space (volume), taking into account the horizontal acoustic modes in the room; free positioning and fixation of the front of the components 8 of the acoustic system along the Ox, Oy, Oz axes, in the direction of the listening point 10; free positioning and fixation of the components 8 of the acoustic system by the angle of inclination of the axis of the component 8 from positive to negative values ​​relative to the listening point 10; correction and synchronization of the phases of the signals of all components at the listening point 10;eliminating the direct mechanical connection of the components 8 of the cable-stayed acoustic system with the floor of the room in order to eliminate the possibility of transmitting parasitic resonances between the components 8 and from the components 8 of the cable-stayed acoustic system to the floor of the room, as well as in the opposite direction, from the ground to the body of the component of the cable-stayed acoustic system, and from there to the speaker baskets; eliminating the propagation of shocks and multi-frequency vibrations from the components 8 of the acoustic system to the floor of the room in which the acoustic system is located and also to eliminate the impact of shocks and multi-frequency vibrations in the opposite direction - from the floor to the acoustic system.

[0015] For high-end acoustic systems, it's time to replace the technology of placing speakers on the floor with a technology that positions the speaker system within the space (volume) of the room. For this purpose, the cable-stayed acoustic system in the mobile version of the frame base has free-swivel, locking wheels, allowing the acoustic system to be freely moved and fixed in the desired location in the room, and directed toward the listening position 10. This listening position has a height adjustment mechanism that locks the speaker system above the floor at a predetermined height. This allows for phase correction and synchronization of signals from all components relative to the listening position 10. The positioned speaker system has no direct physical contact with the floor, as it is located in a room with a fixed, vertical position.is freely suspended on elastic cables 7 fixed to adjustment units 6 of rod 11 of power crossbar 3 of support 2 of cable-stayed acoustic system. Which, at the owner's discretion, can be equipped with any set of components 8: supertweeter module, high-frequency speaker module, high-range midrange speaker module, low-range midrange speaker module, midbass speaker module, bass speaker module. The closer the speakers are to the central radiation axis, the more collected and integral the speaker generates sound radiation. The central radiation axis should be located (as shown in Fig. 12), including taking into account the horizontal modes of the listening room. In this case, the emitter axis of each speaker should be directed towards the listening point 10.The advantage of a cable-stayed acoustic system is the free positioning of each speaker emitter as needed, even in coordinates obtained by calculation using sound adjustment programs in the listening room.
