       The present invention relates to a speaker vibration reduction device for reducing and preventing vibration generated in a speaker system (Woofer Speaker System) by magnetic levitation repulsion by the magnetic structure.

       In a typical speaker system, the bass woofer speaker is difficult to block because of no directivity of sound, and it resonates in all directions.

       When a woofer speaker is installed in an apartment or a multi-furniture apartment, the indoor floor directly touching the lower part of the speaker is connected to the indoor space by touching the ceiling of the lower floor, thus causing resonance. You will feel a great vibration in the lower layer.

       As the vibration of the woofer speaker is transmitted to the floor as described above, the resonance vibrates the floor and transmits resonance noise, which adversely affects sound quality.

       Home theater sound systems, which are used for sound reproduction of other types of audio and video, including DVDs, are becoming more popular because they can realize high quality and delicate sound. The home theater sound system is usually composed of 5.1-channel or six speaker systems, such as the center speaker, front left and right speakers, rear left and right speakers, and bass-oriented woofer speaker system. Dust and abatement devices are known for preventing transmission and maintaining high sound quality.

      For example, a vibration reduction structure that absorbs vibration by laying a marble or a dustproof mat under the speaker and the audio is known.

      However, anti-vibration using marble is a method that allows the vibration medium of the speaker to be primarily transmitted to the marble, and then suppresses the vibration from being transmitted to the secondary structure (bottom) that is in contact with the marble, thereby sufficiently reducing the vibration of the speaker. Could not.

       Similarly, anti-vibration that directly absorbs and reduces vibration by spreading the vibration mat between floors where the speaker touches, absorbs the vibration first by cushioning the vibration mat to mitigate the vibration transmitted to the secondary structure. Since the thickness of the mat could not be increased indefinitely, there was a limit to absorbing vibration, and thus the vibration of the speaker could not be sufficiently reduced.

      As described above, another anti-vibration device that directly absorbs and alleviates vibration by substituting the floor treatment method to prevent vibration by placing the marble or dustproof mat around the surface where the speaker touches is as follows.

      1 is an example of a conventional speaker anti-vibration device, the speaker anti-vibration device of Figure 1, the pedestal for placing the speaker is composed of the upper, middle, lower pedestal (10) (11) 12, respectively, The upper, middle and lower pedestals 10, 11, 12, the vibration buffer plate 13 made of a material such as urethane, rubber plate is formed in the middle of the thickness, respectively, the upper, middle, lower pedestal (10) Between (11) and (12), a shock absorber 14 capable of cushioning such as a spring and a gas absorber is configured, and the vibration of the speaker 15 placed in the upper pedestal 10 is a vibration buffer plate of the upper pedestal 10. (13) and the buffer table 14, the vibration buffer plate 13 and the buffer plate 14 of the suspension pedestal 11, the vibration buffer plate 13 and the buffer table 14 of the lower pedestal 12 in order in order to decrease It was made possible.

     According to the above structure, the vibration of the speaker 15 placed in the upper pedestal 10 is buffered in the vibration buffer plate 13 in the center of the upper pedestal 10, the vibration is reduced and spreads to the vibration buffer plate 13 surface area range . The reduced vibration is reduced by the shock absorber 14 such as a spring, and then the remaining amount of vibration is spread again by the vibration absorbing plate 13 inside the suspension pedestal 11 to the surface area range, and then the shock absorber 14 again. Decreases by).

    In the case of the shock absorber 14 by the elastic material such as the spring, the vibrations transmitted to the area sizes of the upper and middle pedestals 10, 11 and 12, respectively, are blocked by the springs and transmitted, so that the remaining vibrations are transmitted. .

      This structure can be applied not only to woofer speakers but also to all speakers to prevent speaker vibration, and can be applied to a wide range of acoustic systems for home theaters and home theaters such as home theaters.

      However, since the shock absorber is applied, residual vibration can be transmitted to the bottom surface along the shock absorber, and the operation of the shock absorber does not completely block the vibration and the noise source. there was.

Accordingly, an object of the present invention is to prevent the vibration generated from the speaker body during the sound and voice output to the other structure that is in contact with the speaker body to suppress the resonance noise and to prevent the sound quality degradation due to the resonance vibration preventing device To provide.

Another object of the present invention is to prevent the vibration generated from the speaker body from being transmitted to another structure, and avoids direct contact with the speaker body, thereby preventing the speaker vibration from being transmitted to other media. To provide.

As shown in FIG. 3, the magnetic track 40 includes a first magnet 31 disposed in a horizontal plane along a lower surface 21 of the speaker main body 20, and separately from the first magnet 31. The second magnet 32 is disposed along the side surface 22 of the lower surface of the speaker body 20 so as to surround the side surface 22.

The first magnet 31 may be configured by, for example, arranging the flat plate magnet 30 along the lower surface 21 of the speaker body 20 in an insert shape, and the second magnet 32. The flat plate magnet 30 bent in an L shape along the side 22 and the step 23 extending inwardly of the speaker main body 20 may be configured by inserting.

Here, the plate-shaped magnet is not necessarily preferred, but may be more advantageously used in the design or arrangement of the polarity than the shapes of the magnets of other irregularities, rods, circles, and other shapes.

In addition, the magnetic base plate 60 is the same as the first magnet 31 and the second magnet 32 disposed on the magnetic track 40 of the speaker body 20, as shown in FIG.

It consists of a lower plate 62 in contact with the bottom surface.

Here, the magnets 50 disposed on the magnetic base plate 60, like the 1.2 magnets 31 and 32 disposed on the magnetic track 40, mutually induce a magnetic repulsive force in a symmetrical relationship. It is preferable to arrange them correspondingly.

In addition, the coupling means 70, as shown in Figure 3, in order to enable the flow of the speaker body 20 along the upper plate 61 of the magnetic base plate 60, the lower surface ( Steps formed in the speaker body 20 such that the first flow space 71 configured in the 21 and the lower surface 21 of the speaker main body 20 are caught by the upper plate 61 of the magnetic base plate 60.

Application of the detachable structure in which the extension portion 73 of the lower plate 62 is formed in a circular cross section and a bolt 83 is formed at an end thereof so that the bolt 83 is coupled to the screw groove 82 by screwing coupling. It is possible.

 3 to 6, the apparatus for preventing vibration of the speaker according to the present invention represented by FIGS. 3 to 6 is an example in which the speaker main body 20 is directly configured as the magnetic track 40, and the magnetic base plate 60 is correspondingly configured separately. .

However, when the magnetic track 40 is divided from the speaker main body 20 and the magnetic track 40 is removed from the speaker main body 20, the magnetic track 40 is composed of the magnetic track 40 which is dependent on the magnetic base plate 60 as it is. In the same principle, the same or equivalent speaker damping pedestal as the speaker damping device configured above may be configured.

 An example of the configuration of the speaker vibration preventing pedestal 90 is shown in FIG. 7.

 The structure is a vibration component of the speaker main body 20 in which the speaker for outputting sound and voice signals input from external sound and voice mechanical mechanisms, and the voice and sound output components of the speaker built in the speaker body 20 In order to prevent the transfer to other structures is configured by mounting the anti-vibration pedestal 90 around the speaker body 20 peripheral portion.

That is, the magnetic track 40 having the magnet 30 mounted therein and coupled to seat the body of the speaker main body 20 and the magnet 50 disposed with the same polarity with respect to the magnetic track 40 are correspondingly provided. Magnetic base plate 60 for guiding the flow of the magnetic track 40 and the magnetic track 40 along the magnetic base plate 60 so that the magnetic track 40 can be lifted by mutual repulsive force or flow at a certain distance Coupled with a flow space, and includes a coupling means 70 for limiting the flow range of the combination so that the magnetic track 40 can flow in the flow space and the speaker vibration preventing device as described above The same structural features allow for the same or similar dampening results.

Speaker vibration preventing device according to the present invention, as shown in Figs. 3 to 6 constitute a part of the speaker main body 20 by the magnetic track 40, and by configuring the magnetic base plate 60 to be magnetically coupled to the corresponding type By causing the speaker main body 20 to be in an injured state with respect to the magnetic base plate 60 by magnetic repulsive force, vibration generated from the speaker main body 20 may be prevented from being transmitted to another structure by magnetic repulsive force.

The speaker body 20 is capable of magnetic flow. This corresponds to a magnetic track 40 formed by arranging the magnet 30 on the speaker main body 20 and a magnet 50 arranged in the same polarity with respect to the magnetic track 40 on the speaker main body 20 side. Thus, the magnetic base plate 60 for guiding the flow of the magnetic track 40 supports the speaker body 20 as a vibration source by repulsive force so that vibration is not transmitted to other structures.

Referring to FIG. 3, an element to which vibration generated in the speaker body 20 can be transmitted and an object thereof are a magnetic base plate 60, and a space between the upper plate 61 and the lower plate 62. .

However, the transmission path of vibration generated from the speaker main body 20 is in a state blocked by the 1.2th flow spaces 71 and 72.

That is, the first and second magnets 31 and 32 and the first and second magnets 31 and 32 disposed along the lower surface 21 and the side surface 22 of the speaker body 20 correspond to each other. By forming the repulsive force having repulsive force with each other continuously by the magnets 50 on the magnetic base plate 60 symmetrically arranged at the same polarity at the position where Creates a state of injury that is not in contact with the structure.

Maintaining this state prevents any excitation source of the bass band among the sound and voice output components generated from the speaker body 20 from being developed as a vibration source or from being moved to another structure, thereby causing resonance noise or transmitting a vibration medium. The magnetic base plate 60 is not transmitted to the vibration.

That is, since the vibration of the speaker body is not in contact with the other supporting structure (magnetic base plate) supporting it, it is in an injured state, and only the medium through which the vibration of the speaker is transmitted is air and as a result, the speaker vibration is blocked.

On the other hand, the magnetic track 40 of the speaker main body 20 side along the magnetic base plate 60 so that the injured state of the speaker main body 20 can be maintained while flowing in the sound and audio output process, or the magnetic tracks 40 are lifted by mutual repulsive force. It flows along the flow spaces 71 and 72 at a distance.

The magnetic track 40 has a side surface along the side surface 22 of the first magnet 31 and the lower surface of the speaker body 20 arranged horizontally along the lower surface 21 of the speaker body 20. The second magnet 32 is arranged in the shape of wrapping 22, which is intended to sufficiently display the repulsive force, and inserts the magnets 30 along the lower surface 21 of the speaker body 20 into an insert type. The arrangement and configuration is advantageous to prevent the magnet from falling out or falling out. Flat plate magnets are not preferred but are more advantageous for polarity designs or arrangements than the shapes of other uneven, rod or circular and other shaped magnets.

 The magnetic base plate 60 is formed of planes of magnets 50 having the same polarity such that mutual repulsion is displayed with the first magnet 31 and the second magnet 32 disposed on the magnetic track 40 of the speaker body 20. And a lower plate 62 which contacts the bottom surface while guiding the upper plate 61 and the upper plate 61 disposed on the side and the side, while guiding the lower surface of the speaker body 20 to be movable. A large area size at least proportional to the weight load of 20) can form a stable repulsive force in a sufficient magnetic force range.

The magnetic track 40 and the magnetic base plate 60 are configured on the lower surface 21 of the speaker body 20 to enable flow of the speaker body 20 along the upper plate 61 for mutual fluid coupling. The first flow space 71 is provided, and a step 22 is formed in the speaker main body 20 so that the lower surface of the speaker main body 20 is caught by the upper plate 61 of the magnetic base plate 60. The departure of 20 is prevented. In addition, the step 22 of the speaker body 20 is guided and extended to the extension portion 73 so as to flow between the upper plate 61 and the lower plate 62, the upper plate 61 and the lower plate 62. A second flow space 72 is formed between the two to allow the speaker body 20 to flow.

The upper plate 61 and the lower plate 62 constituting the magnetic base plate 60 are configured to be separated from each other as in the configuration of FIGS. 4A and 4B, so that the lower surface of the speaker body 20 is first formed. Accordingly, the upper plate 61 of the magnetic base plate 60 may be seated and the lower plate 62 may be coupled thereunder to conveniently form the magnetic base plate 60 and the magnetic track 40. An upper end portion of the upper portion 61 of the upper plate 61 and the lower plate 62 constituting the extended portion 73 of the lower plate 62 is formed by the flange 80, and the flange 80 is formed by the upper plate 61. The upper plate 61 constituting the magnetic base plate 60 as shown in (a) of FIG. 4, or as shown in FIG. The lower surface of the screw groove 82 is formed, and is coupled to the upper plate 61 Representative application of the detachable structure in which the extension portion 73 of the lower plate 62 is formed in a circular cross section to form a bolt 81 at an end thereof and is coupled to the screw groove 82 by a screw fastening coupling.

 On the other hand, the speaker vibration preventing device according to the present invention, the speaker main body 20 is composed of a magnetic track 40 directly, and corresponding to the magnetic base plate 60 is configured separately. Alternatively, as shown in FIG. 7, the magnetic track 40 is divided from the speaker main body 20 by dividing the magnetic track 40 from the speaker main body 20 and the magnetic base plate 60 is left as it is. When configured as a magnetic track 40 that is dependent on, in the same principle can be composed of a speaker damping pedestal 90 the same or equivalent to the speaker damping device configured above.

 That is, in order to prevent the vibration component of the voice and sound output components of the speaker built in the speaker body 20 from being transmitted to other structures, the vibration preventing pedestal 90 may be configured around the speaker body 20. .

The application of this structure is similarly provided by mounting the body of the speaker body 20 so as to correspond to the magnetic tracks 40 having the same polarity with respect to the magnetic tracks 40 having the magnets 30. Because of the mutual repulsion of the magnetic base plate 60 for guiding the flow of) or can be flowed at a certain distance, even if the vibration of the speaker is transmitted to the upper surface of the magnetic track 40, the secondary vibration source is in contact with the floor surface The vibration is blocked because it is not transferred to the lower plate 62 supporting the magnetic track 40 in the state, and thus the same or similar vibration damping results can be obtained as the speaker vibration damping apparatus.

 Such a speaker damping device and a speaker damping support can be applied not only to the woofer speaker but also to all speakers for speaker damping, and can be widely applied to a home theater acoustic system such as a home theater, a small theater acoustic system, and the like.

 As described above, the speaker vibration preventing device and the speaker vibration preventing pedestal according to the present invention prevent vibrations generated from the speaker body from being transmitted to other structures in contact with the speaker body during sound and voice output, thereby suppressing resonance noise and reducing sound quality due to resonance. In order to prevent the vibration generated from the speaker body from being transmitted to the other structure, the direct contact with the speaker body is avoided, thereby effectively preventing the transmission of the speaker body side vibration to the other structure.

In addition, the speaker anti-vibration device and the anti-vibration pedestal can be applied not only to the woofer speaker but also to all speakers to prevent the speaker vibration, and can be easily applied to home theater acoustic systems such as home theaters and small theater acoustic systems without any improvement or modification of appearance. It can be effective.
