It is explanatory drawing for demonstrating the effect when making it incline so. In FIG. 1, a placement object placed on the placement surface of the placement unit is indicated by reference numeral M. In FIG. 6, a direction parallel to the placement surface is indicated by reference sign X. In FIG. 6, the distance between a certain levitation magnet and the levitation magnet facing the levitation magnet is indicated by reference symbol d.

The damping table 1 according to the present embodiment is used when damping a mounted object such as an acoustic device such as a speaker or other precision equipment. As shown in FIGS. 1 to 6, the vibration damping table 1 according to the present embodiment includes a mounting unit 20 on which a mounting object is mounted, and a base for integrally floating the mounting part 20 and the mounting object. Part 10. As shown in FIG. 1, the placement object (indicated by reference symbol M in FIG. 1) is placed on the placement surface 20 a of the placement unit 20. Details of each component of the vibration damping table 1 will be described below.

As shown in FIGS. 2 and 3, the base portion 10 has a substantially square frame portion 11 and a recess 12, and the recess 12 is parallel to the placement surface 20 a of the placement portion 20. A certain bottom portion 13 and a second inclined portion 14 that is inclined so as to form an angle within a range of approximately 30 degrees to approximately 60 degrees with respect to the mounting surface 20a are formed. The bottom portion 13 is provided with a plurality of positioning pins 16 (that is, positioning members) for positioning the mounting portion 20 with respect to the base portion 10. As will be described later, each positioning pin 16 is inserted into a hole 26 provided in the mounting portion 20. The second inclined portion 14 is provided with a plurality of levitation magnets 18 having, for example, a substantially disk shape. More specifically, each levitation magnet 18 has the same magnetic magnetic pole surface (specifically, a surface having an N pole or an S pole) exposed to the outside of the levitation magnet 18 and a predetermined distance. The second inclined portion 14 is installed in a separated state.

Further, the base portion 10 is provided with a levitation magnet position adjustment mechanism (not shown) for adjusting the position of each levitation magnet 18, and the levitation magnet position adjustment mechanism corresponds to each levitation magnet. 18 can be moved in the direction of the arrow shown in FIG. As a result, the size of the distance between each levitation magnet 18 and each levitation magnet 28 (described later) can be adjusted. Therefore, each levitation magnet 18 and each levitation magnet 28 can be adjusted. The magnitude of the magnetic repulsive force acting between the magnet 28 can be adjusted.

As shown in FIGS. 4 and 5, the mounting portion 20 is configured by a substantially quadrangular pyramid shaped member having a convex portion 22, and the convex portion 22 can be accommodated in the concave portion 12 of the base portion 10. It can be done. A first inclined portion 24 is formed on the outer peripheral surface of the convex portion 22 so as to be inclined with respect to the mounting surface 20a so as to form an angle within a range of approximately 30 degrees to approximately 60 degrees. In the vibration damping table 1 according to the present embodiment, the second inclined portion formed in the concave portion 12 of the base portion 10 when the convex portion 22 of the mounting portion 20 is accommodated in the concave portion 12 of the base portion 10. 14 and the 1st inclination part 24 formed in the convex part 22 of the mounting part 20 are formed so that it may oppose. Specifically, for example, when the second inclined portion 14 of the concave portion 12 is formed to be inclined at an angle of approximately 45 degrees with respect to the mounting surface 20a, the first inclined portion 24 of the convex portion 22 is also formed. It is formed so as to be inclined at an angle of about 45 degrees with respect to the mounting surface 20a.

Further, the mounting portion 20 is provided with a plurality of holes 26, and each positioning pin 16 of the base portion 10 is moved to each position when the convex portion 22 of the mounting portion 20 is accommodated in the concave portion 12 of the base portion 10. It is inserted into the hole 26. Thus, when the convex portion 22 of the placement portion 20 is accommodated in the concave portion 12 of the base portion 10 (that is, when each positioning pin 16 is inserted into each hole portion 26), the placement portion 20 is placed on the base portion 10. The placement unit 20 is positioned. Further, since each positioning pin 16 and each hole portion 26 have the above-described configuration, each positioning pin 16 can also serve as a guide portion that guides movement in a direction perpendicular to the placement surface 20a of the placement portion 20. Become functional. In addition, by providing a mark such as a notch in the base portion 10 and the placement portion 20, the convex portion 22 of the placement portion 20 can be easily accommodated in the concave portion 12 of the base portion 10 (that is, each positioning pin 16 is set to each It may be configured such that it can be easily inserted into the hole 26).

In the vibration damping table 1 according to the present embodiment, as will be described later, a surface parallel to the placement surface 20a due to the magnetic repulsive force acting between each levitation magnet 18 and each levitation magnet 28. The positioning (ie, centering) of the mounting portion 20 can be performed inside. For this reason, in the damping table 1 in this Embodiment, installation of each positioning pin 16 and formation of each hole part 26 may be abbreviate | omitted.

In addition, the first inclined portion 24 of the placement unit 20 is provided with a plurality of levitation magnets 28 having, for example, a substantially disk shape. More specifically, each levitated magnet 28 has the same magnetic pole surface (specifically, a surface having an N pole or an S pole) of the levitated magnet 28 exposed to the outside, and has a predetermined It is provided in a state separated by a distance. Further, each levitation magnet 28 has a first inclination so that the same magnetic pole surface as that of each levitation magnet 18 faces when the convex portion 22 of the mounting portion 20 is accommodated in the concave portion 12 of the base portion 10. It is designed to be installed in the portion 24. Specifically, for example, when the magnetic pole surface having the north pole of each levitation magnet 18 is installed on the second inclined portion 14 so as to face upward in FIG. The magnetic pole surface having the north pole of the levitation magnet 28 is installed on the first inclined portion 24 so as to face downward in FIG. Thereby, when the convex part 22 of the mounting part 20 is accommodated in the concave part 12 of the base part 10, the same magnetic pole surfaces of the levitation magnets 18 and the levitation magnets 28 face each other. Therefore, a magnetic repulsive force acts between each levitating magnet 18 and each levitated magnet 28. In the vibration damping table 1 according to the present embodiment, each levitating magnet 18 and each levitated magnet 28 are composed of magnets having substantially the same size and material.

Here, with reference to FIG. 6, the magnetic repulsive force acting between each levitation magnet 18 and each levitation magnet 28 will be described in more detail. More specifically, FIGS. 6 (a) to 6 (c) respectively mount the same magnetic magnetic pole face of each levitation magnet 18 and each levitation magnet 28 in the damping table 1 shown in FIG. It is explanatory drawing for demonstrating the effect when it makes it incline so that a different angle may be made with respect to the surface 20a. In FIG. 6, a direction parallel to the placement surface 20 a is indicated by a reference sign X. Further, in FIG. 6, a magnetic repulsion force that a certain levitation magnet 18 acts on a levitation magnet 28 facing the levitation magnet 18 is indicated by an arrow. For the sake of explanation, in FIGS. 6A to 6C, the distance between a levitation magnet 18 and a levitation magnet 28 facing the levitation magnet 18 (reference numeral d in FIG. 6). Display) is the same. As a result, the magnitude of the magnetic repulsion force that each levitation magnet 18 acts on the levitation magnet 28 facing the levitation magnet 18 becomes the same.

As shown in FIG. 6B, in the vibration damping table 1 according to the present embodiment, the same magnetic magnetic pole surfaces of the levitation magnets 18 and the levitation magnets 28 are placed on the mounting surface 20a. It is inclined so as to form an angle of approximately 45 degrees. For this reason, when the convex part 22 of the mounting part 20 is accommodated in the concave part 12 of the base part 10, the magnetic repulsive force which acts between each levitation magnet 18 and each levitation magnet 28 is also different from the mounting surface 20a. It acts in a direction that forms an angle of approximately 45 degrees with respect to a parallel direction (indicated by reference symbol X in FIG. 6B) (see FIG. 6B). Thus, the mounting surface is formed by a set of a pair of magnets including a certain levitation magnet 18 and a levitation magnet 28 that faces the levitation magnet 18 when the convex portion 22 is accommodated in the concave portion 12. Magnetic repulsive force can be applied in the direction perpendicular to 20a and in the direction parallel to the placement surface 20a. In addition, each levitation magnet 18 is provided at a position facing each other across the outer peripheral surface of the convex portion 22 when the convex portion 22 is accommodated in the concave portion 12 of the base portion 10. As a result, the placement unit 20 can be positioned in a plane parallel to the placement surface 20a. In other words, the vibration damping table 1 according to the present embodiment includes each levitation magnet 18 and each levitation magnet 28 that faces each levitation magnet 18 when the convex portion 22 is accommodated in the concave portion 12. With a plurality of sets of magnets, the placed object can be damped in a direction perpendicular to the placement surface 20a and in a direction parallel to the placement surface 20a.

In the vibration damping table 1 according to the present embodiment, the inclination angle of each levitation magnet 18 and each levitation magnet 28 with respect to the placement surface 20a is not limited to approximately 45 degrees. More specifically, with respect to the direction in which the same magnetic pole surface of each levitation magnet 18 and each levitation magnet 28 is parallel to the placement surface 20a (indicated by reference symbol X in FIG. 6A). Each levitation magnet 18 and the convex portion 22 are accommodated in the concave portion 12 even when they are inclined to form an angle of approximately 30 degrees (see FIG. 6A). By means of a plurality of sets of magnets 28 to be levitated facing each other, vibration control of the object in a direction perpendicular to the mounting surface 20a and a direction parallel to the mounting surface 20a Can be done. Further, at this time, as compared with the case where the same magnetic magnetic pole surface of each levitation magnet 18 and each levitation magnet 28 is inclined so as to form an angle of about 45 degrees with respect to the mounting surface 20a, Although the magnitude of the magnetic repulsive force acting between each levitation magnet 18 and each levitation magnet 28 does not change, the acting direction becomes different. More specifically, when the same magnetic pole surface of each levitation magnet 18 and each levitation magnet 28 is inclined so as to form an angle of approximately 30 degrees with respect to the placement surface 20a, The same magnetic pole surface of the levitation magnet 18 and each of the levitation magnets 28 is parallel to the placement surface 20a as compared with the case where it is inclined to form an angle of about 45 degrees with respect to the placement surface 20a. The magnetic repulsive force acting in the direction is reduced, and the magnetic repulsive force acting in the direction perpendicular to the mounting surface 20a is increased. In addition, when the same magnetic pole surface of each levitation magnet 18 and each levitation magnet 28 is inclined so as to form an angle smaller than approximately 30 degrees with respect to the placement surface 20a, it is placed. The magnetic repulsive force acting in the direction parallel to the surface 20a becomes too small, resulting in inconvenience.

Further, the same magnetic pole face of each levitation magnet 18 and each levitation magnet 28 is approximately 60 with respect to a direction parallel to the mounting surface 20a (indicated by reference numeral X in FIG. 6C). When tilted to form an angle of degrees, the same magnetic pole face of each levitation magnet 18 and each levitation magnet 28 tilts to form an angle of approximately 45 degrees with respect to the mounting surface 20a. Compared to the case where the magnetic repulsion force acting in the direction parallel to the placement surface 20a is increased, the magnetic repulsion force acting in the direction perpendicular to the placement surface 20a is reduced (FIG. 6 ( c)). In addition, when the same magnetic pole face of each levitation magnet 18 and each levitation magnet 28 is inclined so as to form an angle larger than about 60 degrees with respect to the placement surface 20a, it is placed. The magnetic repulsive force acting in the direction perpendicular to the surface 20a becomes too small, resulting in inconvenience.

Thus, in the vibration damping table 1 according to the present embodiment, even if the size, material, number, and the like of each levitation magnet 18 and each levitation magnet 28 are substantially the same, they are parallel to the mounting surface 20a. By changing the inclination angle of each levitation magnet 18 and each levitation magnet 28 with respect to the direction, the magnitude of the magnetic repulsive force acting in the direction parallel to the placement surface 20a and the perpendicular to the placement surface 20a The magnitude of the magnetic repulsive force acting in a certain direction can be adjusted.

Here, in the conventional vibration control table, each levitation magnet and each levitation magnet are provided so that the same magnetic pole faces are opposed to each other and are arranged to be parallel to the placement surface. . For this reason, the magnetic repulsive force between the pair of magnets acts only in the direction perpendicular to the placement surface (ie, the vertical direction), and in the direction parallel to the placement surface (ie, horizontal). Direction). For this reason, the conventional vibration control table has a problem that it is not possible to perform vibration control of the mounted object in the horizontal direction. On the other hand, as another form of the conventional vibration damping table, there is a vibration damping table in which a magnetic repulsive force acts even in a direction horizontal to the mounting surface. However, in such a vibration control table, it is necessary to additionally provide a pair of magnets in order to apply a magnetic repulsive force to the mounting surface. There is a problem that the manufacturing cost becomes high. On the other hand, in the vibration damping table 1 according to the present embodiment, as described above, it is not necessary to additionally provide a magnet for applying a magnetic repulsive force in a direction parallel to the placement surface 20a. The shaking table 1 can have a simple configuration, and the damping table 1 can be manufactured at a low cost.

According to the vibration damping table 1 of the present embodiment having the above-described configuration, the base portion 10 provided with the levitation magnet 18 and the levitation magnet 28 are provided, and the placement object is placed thereon. And the same magnetic pole surfaces of the levitation magnet 18 and the levitation magnet 28 are provided so as to incline and face each other with respect to the placement surface 20a. In addition, since the placement portion 20 is levitated from the base portion 10 by the magnetic repulsive force of the levitation magnet 18 and the levitation magnet 28, the direction is perpendicular to and parallel to the placement surface 20a. It is possible to realize a simple configuration for performing vibration suppression of the mounted object in the direction, and thus it is possible to reduce the manufacturing cost and the like of the vibration suppression table 1.

In the vibration damping table 1 according to the present embodiment, as described above, the same magnetic magnetic pole surfaces of the levitation magnet 18 and the levitation magnet 28 are approximately 30 degrees to the mounting surface 20a, respectively. It is inclined to form an angle within a range of approximately 60 degrees. Thereby, the magnitude of the magnetic repulsive force acting in the direction parallel to the placement surface 20a and the magnitude of the magnetic repulsion force acting in the direction perpendicular to the placement surface 20a can be set to an appropriate magnitude. It becomes like this.

Further, as described above, the vibration damping table 1 according to the present embodiment further includes a positioning member (specifically, a positioning pin 16) for positioning the mounting portion 20 with respect to the base portion 10, and therefore, the base The mounting portion 20 can be positioned with respect to the portion 10. Further, as described above, the vibration damping table 1 according to the present embodiment is provided with a plurality of combinations of the levitation magnet 18 and the levitation magnet 28, and therefore, the mounting portion 20 and the mounting portion are composed of a plurality of sets of magnets. The figurine can be stably floated with respect to the base portion 10.

Further, in the vibration damping table 1 according to the present embodiment, as described above, the mounting portion 20 is provided with the convex portion 22 having the first inclined portion 24 whose outer peripheral surface is inclined with respect to the mounting surface 20a. The base portion 10 is provided with a concave portion 12 that accommodates the convex portion 22 of the mounting portion 20, and the inner peripheral surface of the concave portion 12 has the concave portion 12 when the convex portion 22 is accommodated. A second inclined portion 14 is provided opposite to the first inclined portion 24 of the convex portion 22. The levitation magnet 18 is provided on the second inclined portion 14 of the concave portion 12, and the levitation magnet 28 is provided on the first inclined portion 24 of the convex portion 22. For this reason, when the convex part 22 of the mounting part 20 is accommodated in the concave part 12 of the base part 10, the levitation magnet 18 and the levitation magnet 28 are inclined and opposed to the mounting surface 20a. Therefore, a magnetic repulsive force acts in a direction inclined with respect to the placement surface 20 a between the levitation magnet 18 and the levitation magnet 28.
