- vibrations which are referred to as "micro” vibrations within the vibration sensitive equipment, such as compact disk (“CD”) players, preamplifiers, amplifiers, phonograph stages, and turntables.
- CD compact disk
- a primary source of vibration in audio equipment is caused by the sound waves generated by the audio equipment, particularly if the equipment is operated at louder volumes, or repeatedly generates audio frequencies at selected harmonic frequencies. These vibrations can cause the extraneous variations which may be detected by a listener.
- vibration sensitive equipment such as audio equipment

- the shelf and shelf support device can be free standing, or alternatively, can be part of a complete cabinet structure.
- the shelf of the present invention may be provided with at least one surface feature which is adapted to attenuate a vibration resonant in the shelf structure.
- Such surface features may include a vibration absorbing material or a plurality of grooves or ridges created on at least a portion of one side of the shelf.
- the surface feature may be provided by a series of regularly spaced, parallel grooves which have been cut or milled into the lower surface of the shelf.
- the shelf support device of the present invention may be provided with at least one surface or composition feature which attenuates a vibration which is resonant in the shelf structure.
- prior art shelf support devices are made of a materials such as wood, or tubular aluminum, tubular steel or the like, which can aid in the transmission of any vibration to the shelf.
- a shelf support device according to invention may be made of a vibration absorbing material (such as a composite fiber material) or a vibration dispersive material (such as a solid metallic rod).
- the shelf support device may be a single support or a plurality of support devices, such as, for example, a plurality of carbon fibre tubes or a plurality of solid aluminium rods.
- a vibration control device for use with a vibration control support structure comprising a shelf and a shelf support device, wherein the vibration attenuating is adapted to be connected between the shelf and the support device, and wherein the vibration control device is adapted to be fastened to the shelf using an interference fit.

- FIG. 9 is a bottom view of a shelf according to an alternative embodiment of the invention.
- FIGS 1 OA through 10C are side elevation of shelves according to alternative embodiments of the invention.
- vibration control support structure 10 for use with vibration sensitive equipment is shown having two support shelves 12, and vertical shelf support devices 14. More specifically, the shelves are supported by circular support sections 14 in the shape of circular rods or tubes. The two support shelves are stacked one above another so that individual electronic components may be placed on each shelf.
- each of the shelves 12 is manufactured from a 16 mm thick sheet of wood veneer MDF (Medium Density Fibreboard).
- the shelves12 may be fabricated from any of a variety of materials, including, wood laminates, composite wood materials such as particle board, chip board, or the like, metal, plastic, or glass panels, composite materials such as carbon fibre materials, or various epoxy, fibreglass or acrylic resin based materials, or stone such as granite, or combinations thereof.
- the vertical shelf support devices 14 are fabricated from hollow metallic tubes. However, they might also be fabricated from solid metallic rods, and in particular, solid aluminium rods. It is also noted that the vertical shelf support devices 14 may be made from other materials including composite materials such as carbon fiber and fibre-reinforced plastic (FRP). It has been shown that improvements in sound quality from music played from components placed on shelves or platforms supported by carbon fiber supports is substantial when listening tests are conducted. Also, switching from hollow aluminum tubes to solid aluminum rods as support elements between the shelves has been found to cause a general improvement in sound, due to non-ringing of tubing and an increase in mass for vibration transfer.
- FRP fibre-reinforced plastic
- the vibration control device 16 is a collar 16 into which one or two vertical shelf support devices 14 are screwed.
- Each collar 16 is fastened to a shelf 12 using an interference fit.
- An interference fit also known as a press fit, is a fastening between two parts which is achieved by friction after the parts are pushed together, rather than by any other means of fastening.
- An interference fit is generally achieved by shaping the two mating parts so that one or the other (or both) slightly deviate in size from the nominal dimension.
- a collar 16 is of a slightly larger diameter than an aperture in the shelf 12 into which the collar 16 is inserted.
- interference refers to the fact that one part slightly interferes with the space that the other is taking up.
- a shaft of a collar 16 may be slightly oversized, and a hole in the shelf 12 (through which the shaft of the collar is going to pass with an interference fit) may be slightly undersized.
- the two parts interfere with each others occupation of space; the result is that they are each compressed so that they are locked together.
- Formulas exist to compute the "allowance" (planned difference from nominal size) that will result in various strengths of fit such as loose fit, light interference fit, and strong interference fit.
- the value of the allowance depends on which material is being used, how big the parts are, and what degree of tightness is desired. Such values have already been calculated for many standard applications, and they are available to engineers in the form of tables, obviating the need for re-derivation. Thus, if a light interference fit is desired for a 10 mm (0.394 inch) shaft made of 303 stainless steel, an engineer can look up the required allowance in a reference book or computer program.
- the method of using force is achieved with the use of a press that can press the parts together with very large amounts of force.
- the amount of force applied may be anything from a few pounds for small parts to hundreds of tons for the largest parts.
- the edges of the shaft and hole may be chamfered (beveled). The chamfer forms a guide for the pressing movement, helping to distribute the force evenly around the circumference of the hole, and helping the pressing operation to be smoother and more easily controlled.
- the method of changing the size of the parts by heating relies on the fact that most materials expand when heated and shrink when cooled.
- and enveloping part may be heated and assembled into position while hot, then allowed to cool and contract back to their former size, except for the compression that results from each interfering with the other.
- an enveloped part m ay be cool ed before assem bly s uch that it sl ides easi ly i nto its mating/enveloping part. Upon warming, the enveloped part expands and interferes with the enveloping part. Cooling is often preferable as it is less likely than heating to change material properties.
- a collar 16 adapted to be fastened to an MDF or particle board shelf 12 using an interference fit is 1-2 thousandths of an inch larger than the hole 18 in the shelf into which it is positioned.
- the diameter d1 of the circular shaft 20 of the collar is 0.751 inches
- the diameter d2 of the circular hole 18 is 0.750 inches.
- MDF or other particle boards or woods give with use and so accommodate interference fits of 1 -2 thousands of an inch.
- the collar is made from brass.
- the collar 16 reduces in size (by 1 or 2 thousandths of an inch depending on the size of the collar) allowing it to be simply pressed into the hole 18 of the shelf 12.
- the collar 16 expands back to it normal size it presses hard against the side wall of the hole 18 exiting vibration towards it and increasing longevity of wear.
- the collar 16 may be lapped in to the hole 18 to obtain an interference fit.
- the collar 16 is adapted so that it protrudes from the upper 20 and lower 22 surfaces of the shelf 12 by approximately 1 -2mm. In this way, when the vertical shelf support devices 14 are screw fitted to the collar 16, the support devices 14 do not contact the shelf 12. This prevents compression of the shelf 12 and allows vibrations to dissipate towards the collar 16 while maintaining rigidity.
- the collar 16 may be made from other suitable material.
- the collar 16 is made from a heavy material like brass or phosphorus bronze, and the support devices 14 made from a relatively light material like aluminium, stainless alloy or composite so that the support devices 14 do not interact with the collar 16. It is also preferable to make the support devices 14 thicker than the collar so as to assist in dissipation of vibrations.
- an alternative embodiment of a vibration control device for use with a vibration control support structure comprises apertures 24 in addition to a threaded barrel 26 for receiving the screw of a shelf support device 14.
- the apertures 24 are spaced apart equally around the circumference of the shaft 20 of the collar 16 and extend longitudinally through the collar 16. The apertures 24 help to decouple the support devices 14 from the shelf 12, as shown in Figure 5.
- FIG. 6 an alternative embodiment is shown wherein the aperture 27 in an MDF shelf 12 is formed in two portions, each portion having a different diameter.
- the aperture provides a seat 28 against which a shoulder 30 of a vibration control device 32 according to the invention can be positioned.
- the vibration control device 32 of Figure 6 is adapted to be fastened to the shelf 12 using an interference fit by being sized 1-2 thousandths of an inch larger than the aperture 26 in the shelf 12 (since the shelf 12 is formed from MDF).
- the diameter D"1 of the circular shaft of the vibration control device 32 is 0.501 inches
- the outer diameter D"2 of the vibration control device 32 is 0.751 inches.
- the diameter d"1 of the smaller portion (for receiving the shaft of the vibration control device 32) of the circular aperture 27 is 0.500 inches
- the diameter d"2 of the larger portion of the circular aperture 27 is 0.750 inches.
- the dimensions of the vibration control device 32 are 1 thousandth of an inch larger than the aperture 27 in the shelf 12 into which it is to be fastened with an interference fit.
- the vibration control device 32 may be adapted to be fastened to the shelf using an interference fit by being sized 0.5-1 thousandths of an inch smaller than the aperture in the shelf.
- FIG. 7 shows yet another embodiment of the invention, wherein the vibration attenuation device 70 comprises a mechanical damper ring 72 positioned around a tapered base 74 of the vibration attenuation device 70.
- the mechanical damper ring 72 is made from a hard stainless steel, whereas the vibration attenuation device 70 is made from brass or phosphorus bronze.
- the purpose of the damper ring is to restrict or prevent vibrations from returning to the shelf 12 and to help divert the vibrations towards the support devices instead.
- the shelves 12 have a width of 75 cm wide, a depth of 50 cm deep, and a thickness of 2 cm.
- shelves 12 can have a wide variety of dimensions, but typically, the shelves are between 50 and 125 cm wide, 45 to 60 cm deep, and 1 .25 to 3 cm thick.
- shelves 12 are preferably substantially flat.
- a shelf 12B is fabricated so as to have a plurality of spaced apart and parallel venting apertures 82 for facilitating heat dissipation.
- the shelf 12B is also fabricated to have a plurality of channel grooves 84 provided in the lower surface of the shelf.
- the grooves 84 are substantially perpendicular to the venting apertures 82 and are preferably routered into the underside of the shelf 12B.
- the channeled grooves 84 can vary in depth, but preferably are between 1 mm and 5 mm. Preferably, the depth of channeled grooves 84 is such that they do not extend through more than 75% of the thickness of shelf 12B, more preferably, through no more than 50% of the thickness of shelf 12B, and even more preferably, no more than 25% of the thickness of the shelf 12B.
- channeled grooves 84 have a common width of 10mm and all grooves 84 have a square cross-section shape. Other groove shapes, such as semi-circular, V-shaped or the like, may also be used. As illustrated by the embodiment of Figure 9, the depth, width, number, and spacing of such aperture and groove features can be varied depending on the nature of the shelf design, the shelf construction material or other factors. By simple measurement of the shelf vibration during testing, these design parameters can be optimized.
- the embodiment of Figure 9 is fabricated to have a plurality of elongate channel grooves 94 provided in the lower surface of the shelf 12C.
- the grooves 94 are arranged in a pattern extending outwardly from the centre of the shelf 84.
- Also provided in the lower surface of the shelf 12C proximate the corners are oblong- shaped grooves or cut-outs 96.
- the oblong-shaped grooves 96 increase in width with increasing distance from the corner at which they are positioned.
- the design of grooves in Figure 9 is thought to focus vibrations in the shelf towards the edges of the shelf and away from any equipment supported on the upper surface of the shelf.
- Figures 10A-10C the concept of focusing vibrations away from the upper surface of a shelf 12 can be extended to the design of the shelf sides by fabricating the shelf to have a larger surface area on the lower side.
- Figure 1OA shows the edge of a shelf having a sloped straight edge 98.
- Figure 1 OB shows the edge of a shelf having a first sloped portion 100 and a second vertical portion 102.
- figure 10C shows the edge of a shelf having a rounded edge 104.
- the footprint area of the lower side of the shelf is larger than the footprint area of the upper side of the shelf. This is understood to cause vibrations in the shelf to be attracted or focused away from the upper surface and towards the lower surface of the shelf.
- the vibration control device 110 comprises a barrel 110 for receiving the screw of a shelf support device 14.
- the threaded barrel 110 is provided with a tapered annular protrusion 112 towards one end of the barrel 110, and a second annular protrusion 114 towards the other end of the barrel 110.
- An aperture 1 16 in an MDF shelf 12 is formed in two portions, each portion having a different diameter. In this way, the aperture provides a seat 118 against which a shoulder 120 of a receiving sleeve 122 is positioned. At the opposite end to the shoulder 120, the receiving sleeve 122 is formed with an inwardly projecting seat 124 against which the tapered annular protrusion 1 12 of the vibration control device is positioned (when the vibration control device 110 is inserted into the receiving sleeve 122).
- the vibration control device 110 and the receiving sleeve 122 are both formed from brass or phosphorus bronze.
- the vibration control device 110 is adapted to be inserted into the receiving sleeve 122 to form an interference fit between the annular protrusions 112, 114 and the inner surface of the receiving sleeve 122.
- the outermost diameter of the annular protrusions 1 12, 1 14 is adapted to be 0.5-1 thousandths of an inch smaller than the internal diameter of the receiving sleeve 122.
- the vibration control device 110 may be inserted into the receiving sleeve 122 using force.
- temperature may be used to change the size of the vibration control device 110 and/or receiving sleeve 122 before they are fastened together.
- the vibration control device 110 may be cooled before assembly such that it slides easily into the aperture of the receiving sleeve 122. Upon warming, the vibration control device 110 expands and interferes with the receiving sleeve 122.
- the shelf 12 may not enable an aperture 116 to be sized to the high degree of accuracy required to provide an interference fit. Provision of the metal receiving sleeve 122 addresses this problem since it is adapted to connect to the MDF shelf 12 and provide an accurately sized aperture for the vibration control device 1 10 to be inserted into and connected with an interference fit.
- the majority of the shelf 12 can then be formed from MDF which is lighter in weight and less expensive then the metal used for the receiving sleeve 122. This reduces the amount of metal used in the shelf 12 whilst still enabling the provision of an accurately sized aperture for receiving a vibration control device 110 according to an embodiment.
- the receiving sleeve 128 is formed, towards one end, with first 130 and second 132 rows of spaced apart circular apertures around the circumference of the sleeve 128.
- the first row of apertures 130 comprises apertures which are smaller in diameter than those of the second row 132.
- the purpose of the apertures is to draw or attract vibrations in the sleeve 128 towards the end of the sleeve 128 comprising the apertures. In this way, vibrations are directed in a downward direction and away from the shelf 12 in which the sleeve 128 is fitted.
- the sleeve 128 restricts or prevents vibrations from returning to the shelf 12 and helps divert the vibrations towards a support device 14 instead.
- any reference signs placed between parentheses shall not be construed as limiting the claim.
- the word “comprising” does not exclude the presence of elements or steps other than those listed in a claim.
- the word “a” or “an” preceding an element does not exclude the presence of a plurality of such elements.
- Embodiments can be implemented by means of hardware comprising several distinct elements. In the device claim enumerating several means, several of these means can be embodied by one and the same item of hardware. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
