Background Art

[0004] In a sound speaker system such as a Hi-Fi system, when a speaker such as a sound box starts to reproduce sound such as music, various vibration motions such as horizontal vibrations caused by the movement of the speaker driver start. These movements also generate vibrations and resonances on the surface material of the speaker cabinet and vertical vibrations that are reflected between the speaker and the support surface on which the speaker is installed. The combination of these vibrations results in a substantial distortion to the purpose of the Hi-Fi system, that is, the purity of the sound. Similar problems can occur in other situations. This is disadvantageous. [[ID=​​​[Overview of the project]

[0019] In the following explanation, terms such as "upper" and "lower" refer to the orientation in which they are viewed in the drawing.

[0020] Referring to the drawings, isolator 1 is provided. Isolator 1 is intended to be used with at least four different product families: loudspeaker isolation feet, audio component feet, computer / bookshelf speaker stands, and audio racks.

[0021] Isolator 1 is baseThe base has two components, which are preferably formed from an elastic material such as rubber or a similar plastic material, to reduce the possibility of the base sliding on the material or structure on which the base is installed.

[0022] base Shell 3 is attached to base 2. Shell 3 is attached to base 2 via an adjustment mechanism. The adjustment mechanism is screwed onto its inward-facing surface. First It is equipped with ring 4. First The ring 4 is engaged with the shell 3 by two semicircular members 5. The two semicircular members 5 are connected by screws 7. First By completely penetrating the opening 8 of the ring 4, and by engaging the head of the screw 7 within the threaded socket 9 of the shell 3 while being held in engagement with the semicircular member 5 by the stepped non-threaded opening 10 passing through the semicircular member 5, First The ring 4 engages with the lip 6 (Figure 4) below and is fixed to the shell 3. Therefore, First Ring 4 is held by shell 3, but rotates freely relative to shell 3.

[0023] The threaded portion is on the outward-facing surface. Second A ring 11 is provided, and its threaded portion is First It engages with the threaded portion of ring 4. Second Ring 11 is, First The rotation of ring 4 First Depending on the rotation direction of ring 4 Second The ring 11 is held against rotation so as to be deployed or retracted relative to the shell 3 (as described later).

[0024] base 2 is in any desired manner by bonding or the like. Second It is connected to ring 11.

[0025] Support devices are provided to enable the isolator to be connected to or to a structure such as a speaker or soundbox.

[0026] The shell 3 has an opening 15 at the end of the isolator 1 opposite the base 2. The opening 15 has inwardly projecting projections 16, including three projections 16 that give a recess 17 between them. A guide 18 is provided, which is held in the shell 3 by a screw 19 (Figure 4) passing through a stepped opening 20 and engaging in a threaded recess 21 at an adjacent end of the guide 18. At the other end of the guide 18, Second There is a lobe 22 that engages with a slot 23 on the inner surface of the ring 11. The lobe 22 is movable longitudinally within the slot 23, but the position of the lobe 22 within the slot 23 is Second The rotational movement of the shell 3 relative to the ring 11 is prevented. The screw-shaped recess 21 is preferably provided on the upper end 25 of the guide 18 on a lobe 24 that protrudes outward in the same direction from the stem of the guide 18 but is separated from the lobe 22. The guide 18 is Second It is positioned between two inwardly projecting ribs 26 that protrude inward from the ring 11.

[0027] In this embodiment of the present invention, the support structure includes a connecting arm 27. The connecting arm 27 has one end located within the shell 3, and the other end preferably extends through an opening 15 so that the connecting arm 27 can engage with a structure such as a Hi-Fi speaker connector.

[0028] The connecting arm 27 may be configured as follows: A central pendulum member 28 is placed inside the shell 3, which has a plurality of ventilation holes 29, such as three ventilation holes 29 that extend outward at approximately equal intervals and approximately perpendicular to the longitudinal axis of the pendulum member 28. Similar ventilation holes 30 are provided in the recess 17 of the shell 3. The ventilation holes 30 also extend inward at approximately perpendicular to the longitudinal axis of the shell 3.

[0029] pendulum The other end of member 28 has a recess therein, which has a circular cross-section, and a tubular isolation member 35 is placed inside it. isolation Inside member 35, short There is a tubular member 36. short tubular Component 36 is made of metal. isolation Component 35 is metal pendulumMember 28 and Short tubular metal member It is composed of 36 flexible cushioning materials. isolation Member 35 and Short tubular member 36 is held in place by a support member 37 positioned within the upper portion 33 of the pendulum member 28. The support member 37 is supported by a washer 38 and First They are held in place by the circlip 39, and both are, as can be seen in Figure 4, isolation At the end of member 35 support It is located within the lap joint of member 37. First Circlip 39 is upper part It is also clipped into the recess in the inner wall of 33. isolation Member 35 and Support member 37 is held in place by engagement with the pendulum member 28.

[0030] The connecting arm 27 can also be engaged with a structure such as a Hi-Fi speaker connection part (not shown) when in use. For connection It has bolt 40 there. For connection The bolt 40 has a long, rectangular opening through which the bolt 43 passes. support It is fixed to the screw-shaped recess of member 37. This is best seen in Figure 4.

[0032] In a preferred embodiment of the present invention, three links 45 are provided. Each link 45 comprises an arm 46 having a recess or stepped opening 47 at each end. A bearing 48 is disposed within each opening 47, and its outward-facing surface 49 is arc-shaped. When the bearing 48 contacts the stepped opening, preferably the contact surface is formed to coincide with the arc-shaped surface 49. The bearing 48 is, SecondCirclip 50, stepped washer 51, and stepped washer 51, Second The link is held in place by a screw or bolt 52 that passes through a receiving threaded recess in either the vent hole 29 or 30 via a circlip 50 and a bearing 48. The effect is that the link becomes pivotable relative to each vent hole 29 and 30 and also tiltable for the arcuate surface 49. This gives the link a wide range of motion relative to the connecting arm 27 and the shell 3. This means that the connecting arm 27 has a wide range of motion relative to the shell 3. pendulum These degrees of freedom around component 28 allow for improved dynamics of the sound from the speaker.

[0033] During use, the connecting bolts 40 are attached to a structure such as a loudspeaker, and the base 2 is placed on a support surface. There may be any number of isolators according to the present invention used to support the structure, but there are usually three or four. First Ring 4 is rotatable to adjust for leveling as needed if the support surface is not horizontal.

[0034] When vibrations occur in the structure, these vibrations are eliminated or at least reduced by the relative movement between the connecting arm 27 and the shell 3.

[0035] Referring to Figure 6, each link 45 is movable over the range shown by the dashed line. When using three arms, the arc-shaped surfaces of the inward-facing surface of the stepped opening 47 and the outward-facing surface of the bearing 48 49 The arm 46 moves in any direction in which it can swing.

[0036] Figures 7-18 show an alternative isolator 60, which is a simplified version of the isolator 1 shown in Figures 1-6. The isolator 60 has a base portion 61 and a cover or shell including a cover portion 62. A mechanism is provided to expand and contract the isolator 60 by making the base portion 61 and the cover portion 62 rotatable relative to each other. In the illustrated embodiment, the ring member 63 is provided with a finger grip 64 around its outward-facing surface.

[0037] Within the base portion 61 and the cover portion 62 is a pendulum member 65 having a number of, preferably three, ventilation holes 66 extending outward from there. The ventilation holes 66 are spaced equally apart around the pendulum member 65. The pendulum member 65 is located inside or slightly below an annular member 67 having three inwardly projecting portions 68 and three inwardly extending ventilation holes 69. Similar to the previous embodiment, the link 70 is provided with opposing stepped openings 71 and 72, each receiving a bearing 73, which is held in place by a circlip 74 that can "snap" into a groove on the inward-facing surface of the opening 71 or 72. Each ventilation hole 66 or 69 has a central threaded recess 76, thereby allowing a screw 75 to pass through the bearing 73 and be held within the threaded recess 76. Thus, each link 70 is able to swing freely relative to the ventilation holes 66 and 69. protruding inward The protruding portion 68 is inclined downward and inward. Here again, the outer surface of the bearing 73 and its receiving recess of the link 70 are arc-shaped.

[0038] The cover portion 62 is also substantially annular in shape and has an inward-facing projection 80. The inward-facing projection 80 is on the annular member 67. Extend It coincides with the protruding portion 68. The bolt 83 passes through the opening 82. Screw-shaped So that it can be fixed in the recess 81, protruding inward The lower surface of the protruding portion 68 has a screw-shaped recess 81. Inward The protruding portion 80 has an opening 82. Inward The protruding portion 80 is protruding inward The pin 84, which will be positioned within the opening 85 of the protruding portion 68, is also held in place.

[0039] A disc 90 is provided, having a circumferential groove 91 on its outward-facing surface in which an O-ring 92 is placed. The opening of the disc 90 107’ The pendulum member 65 is secured by a bolt 107 that passes through the screw-shaped receiving opening or recess 94 of the pendulum member 65. The O-ring 92 substantially prevents direct contact between the disk 90 and the cover portion 62.

[0040] Screw part A screw-shaped height adjustment member 95 is provided at 96, the outer surface of which is threaded. The threaded portion 96 is engaged with the ring member 63 by the threaded portion 100.

[0041] The pendulum member 65 has three raised portions 102 at its upper end. The cover portion 62 has a downward-hanging arm 111 which is open in the center and receives a bolt 108. Base 61 and Cover 62 are positioned but are threaded to allow rotation between them. Arm 111 has an outward overhanging flange 112, which is positioned within the notched portion 113 in the assembled configuration.

[0042] Similar to the semicircular member 5 in the configuration shown in Figures 1-6. Cover A semicircular member 105 is provided to be fixed to 62. A bolt 104 is provided to fix the semicircular member 105 to the ring member 63.

[0043] The annular member 67 engages with the cover portion 62 by engaging with the notched portion 114 of the cover portion 62, and the disc 90 is also positioned within the notched portion 115 of the cover portion 62. Another disc 116, made of anti-slip material, is positioned within the notched portion on the upper surface of disc 90.

[0044] Similarly, a lower cover plate 112, preferably made of a “non-slip” rubber or plastic material, engages within the notched portion 113 but protrudes from it. 104 However, it is positioned above the lower cover plate 112 to provide further support to the lower cover plate 112.

[0045] The use of this embodiment of the present invention, as in the previous embodiment, separates two structures, but allows the isolator to be placed on one structure and receive the other structure on top of it. It is assumed that typically three or four isolators according to this embodiment of the present invention may be used.

[0046] Figures 19-25 illustrate yet another embodiment of the present invention. This embodiment allows for the positioning of a speaker or other device, such as a computer / bookshelf speaker, on a stand while also providing isolation from the structure on which the speaker or other device was previously located.

[0047] The device 120 can be positioned on a base 121. The base 121 comprises a base 122 and a movable upper plate 123. The base 122 may consist of a peripheral upright member 124 and a lower plate 125. The lower plate 125 has a plurality of pins 126. Figure 21 shows eight pins. The pins 126 engage with a receiving opening member 127.

[0048] The upper plate 123 is connected to the peripheral member 124 as follows. A number of links 130 are provided, six of which are shown in Figure 21. These are basically the same as the links described in the previous embodiment and will not be described in detail. The upper end of each link 130 is pivotably connected to a ventilation hole 131 extending from the peripheral member 124. The lower end of each link 130 is connected to the upper plate 123. This is achieved by providing a downward-hanging arm 132 from the lower surface of the upper plate 123. downward droop The arm 132 may be configured as part of the upper plate 123, or as a separate arm fixed to the lower surface of the upper plate 123, as in the embodiments illustrated and described herein. downward droop The arm 132 has flanges 133 on each side of the arm that can be bolted to the lower surface of the upper plate 123. downward droop The upper end of the arm 132 is positioned within the notch 134 on the lower surface of the upper plate 123.

[0049] Link 130 is, downward droop It is pivotably mounted on the ventilation hole 135 extending from the arm 132. Therefore, along with the arc-shaped opposing surface of the bearing and the recess into which the bearing fits, downward droop The pivoting motion of the arm 132 allows the upper plate 123 to be substantially isolated from the base 122.

[0050] An anti-slip panel 136 is provided on the underside of the lower plate 125.

[0051] In this embodiment, devices such as speakers can be mounted on the upper plate 123 such that their movement is substantially isolated from the base 122.

[0052] Figure 26 shows the configuration in use of the embodiment of the present invention described first. Four isolators 1 are shown engaged with the underside of the speaker box to provide substantial isolation of the speaker cabinet from the support surface on which the isolators are mounted.

[0053] Figures 27 and 28 show alternative methods for achieving isolation between the device and the support surface. A substantially rigid plate 140 is provided on which a device 142, such as a speaker box, can be mounted. Multiple arms 143 are provided. Rigid body They extend outward from plate 140. Four such arms are shown in the figure. An isolator is attached to each arm 143. In the figure, the isolator is the one described herein in the first embodiment.

[0054] During use, the isolators 1 are mounted on a rigid plate 140, and the height of each isolator is adjusted to achieve a stable platform. Devices such as speaker boxes 142 can then be placed on the rigid plate 140, and the configuration provides substantial physical isolation between the device 142 and the surface on which the isolators 1 are positioned during use.

[0055] Further embodiments of the present invention are shown in Figures 29-37. These embodiments are substantially similar to the embodiments in Figures 7-18, except that the movement damping of the link 70 is provided without the height adjustment feature being shown. In these embodiments, the cover portion 62 is Ring The notched portion in which the damping member 141 is located 62’ It has been modified to incorporate the following. The damping member 141 is as can be seen in Figure 31. Damping The cross-section passing through member 141 may have a truncated wedge shape. The disc 90 is provided with a downward-facing annular flange 142, the downward-facing surface of which is positioned opposite to the inward-facing surface of damping member 141.

[0056] The disc 90 is fixed to the pendulum member 65 by bolts 107, and the pendulum member 65 is connected to the cover portion 62 via a link 70. The cover portion 62 is positioned relative to the disc 90 by a damping member 141. Therefore, any movement of the link 70 is damped by the damping member 141. A suitable material for the annular damping member 141 is a silicone rubber material with a Shore hardness of approximately 25. It is also considered that materials with a Shore hardness in the range of approximately 15 to 35 may be usable. This embodiment is expected to substantially eliminate even small vibrations of about 1 to 2 microns.

[0057] This configuration is essentially used as the embodiment shown in Figures 7-18, but with the added feature of damping acted upon by the damping member 141. [Industrial applicability]

[0058] This invention is used to eliminate or reduce the transmission of vibrations in speaker systems and the like in order to improve the quality of sound emitted into the environment.

[0059] Technical effects The present invention provides an effective means for eliminating or reducing unwanted vibrations in devices such as soundboxes, in an embodiment that is easy to assemble and use. Some embodiments also include measures to dampen the relative movement between the support surface and the vibration-generating device. Some embodiments also include height adjustment of the isolator.

[0060] It will be apparent to those skilled in the art that countless variations and / or modifications can be made to the embodiments described above without departing from the broad general scope of this disclosure. Therefore, these embodiments should be construed in all respects as illustrative and not restrictive.
