677).

The stage 16 for performing the aerobics or the like on the vibration device 1
When attached to the diaphragm 17 of, as shown in FIG.
It is mounted on the lower surface of the vibration plate 17 through a mounting member 18 composed of a foamed polyethylene panel 18a and a resonance plate 18b (Japanese Utility Model Publication No. 61-197782).

(Problems to be Solved by the Invention) In the conventional vibration device mounting structure, the exciter 11 is used.
Since the vibration is propagated to the case body 13 by the vertical movement of the case body 1, the case body 1 is prevented from propagating to the floor A.
It is necessary to provide a gap between the floor 3 and the floor A, and it is indispensable to provide the leg 19 on the lower surface of the stage 16 to secure the gap.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a vibrating device mounting structure in which a magnet plate serves as a leg of a vibrating panel and does not propagate a large vibration to a floor or the like.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a vibrating device including a vibrating exciter having an exciting coil attached thereto and a magnet facing the exciter at a predetermined interval. In a structure for mounting a vibrating device mounted on a vibrating panel, the vibrating panel includes a vibrating plate located above and a fixed plate located below and facing the vibrating plate, and the exciter body vibrates through the vibrating plate. The magnets are attached to the lower surface of the plate via a magnet plate, and the magnet plate is formed so as to project downward from the lower surface of the vibrating panel.

(Operation) According to the present embodiment, by applying an electric signal of a predetermined frequency to the exciting coil, the exciter vibrates and the vibration is transmitted to the diaphragm. Further, since the magnet plate is formed so as to project downward from the lower surface of the vibration panel,
When the vibrating panel is placed on the floor, the magnet plate functions as a leg of the vibrating panel.

(Embodiment) FIGS. 1 and 4 to 6 show an embodiment of the present invention, in which 20 is a rectangular vibration panel used as a karaoke stage, and 30 is a corner of the vibration panel 20. The reference numeral 50 denotes a handle of the vibration panel 20.

As shown in FIG. 5, the vibrating panel 20 includes a surface material 21 made of a wooden flooring material, a cushion plate 22 made of ABS resin, and an upper plywood (vibrating board) 2.
3, a vibration damping member 24 made of urethane foam, a lower plywood (fixing plate) 25, and a bottom sheet 26 made of vinyl chloride are sequentially laminated from above.
A wooden frame 27 is attached to each of the side surfaces 25 to 25, and a rubber frame guard 28 is attached to the outer surface of the frame 27. Further, device accommodating holes 29a are formed in the vibration panel 20 near the respective corners of the vibration panel 20, that is, in the portion to which the vibration device 20 is attached, in the lower plywood 25 and the bottom sheet 26. As shown in FIG. 6, the handle 6 is attached to the anti-vibration member 24 on the side.
The handle accommodating holes 29b for accommodating the below-described arm portions 62 of 0 are respectively provided. Further, the frame 27 is provided with an insertion hole 27a of the arm portion 62 which faces the handle accommodation hole 29b.

The vibrating device 30 includes an exciting body 31 and a magnet 32. The exciting body 31 has an exciting coil 33, an annular winding rod 34 incorporating the exciting coil 33, and a leaf spring 35 connected to the winding rod 34. The inner circumference side of the winding rod 34 and the leaf spring Three
The tip of 5 is connected by a rivet 36, and the winding rod 34 is vibrable. Further, a rubber bush 38 is attached to the inner peripheral surface of the annular mounting member 37, and the base end of the leaf spring 35 and the lower end of the vibrating frame 39 are attached to the outer peripheral surface thereof. Lead wire 4
0 is connected. Further, the upper end of the vibrating frame 39 is screwed to the lower surface of the upper plywood 33 with a screw 41 so that the vibration of the exciter 32 is propagated to the upper plywood 23.

The magnet 32 is formed in an annular shape, and is located below the exciter body 31 with a gap between the magnet body 32 and the magnet body, and the magnet 32 is located on the upper surface of the magnet body 32.
A magnet protection plate 42 having the same shape as is attached. The magnet 32 is attached to the upper surface of the magnet plate 43, and the magnet plate 43 projects downward from the lower surface of the vibration panel 20 in a dish shape.
The peripheral edge thereof is screwed to the bottom sheet 26 and the lower plywood 25 with screws 44.

The handle 50 is formed in a pipe shape, and as shown in FIG. 6, a grip portion 51 extending along one side in the width direction of the vibrating panel 20, and the insertion hole 27 from both ends of the grip portion 51.
a and the arm portion 52 extending to the handle accommodating hole 29b,
A stopper 55 made of rubber is fixed to the tip of the arm portion 52 with a screw 54 via a washer 53, and when the arm portion 52 is pulled out via the grip portion 51, the stopper 55 is a peripheral edge of the insertion hole 27a. It comes into contact with.

According to the present embodiment, when a music signal from a sound source is applied to the exciting coil 33 via the lead wire 40, the exciter 31 moves up and down between the magnet 32 and the magnet 32 in accordance with the music signal. Vibrates, and the vibration is generated by the vibrating plate 39.
Propagates to the upper plywood 23 of the vibration panel 20 via
Further, it propagates to the surface material 21 through the cushion plate 22.

When the vibrating panel 20 is placed on the floor, the magnet plate 43 serves as a leg as shown in FIG. 4, and the vibration isolator 24 is provided on the lower surface of the upper plywood 23.
Since the vibration is propagated to the plywood 23, it is difficult for the vibration to propagate to the lower plywood 25 side.
It does not vibrate significantly. Therefore, the floor A is not damaged by the magnet plate 43, and no large vibration is propagated downstairs or the like.

In the above embodiment, one vibration panel 20 is used, but a plurality of vibration panels 20 may be arranged to form a stage for performing aerobics or the like.

(Effects of the Invention) As described above, the present invention is a vibration device in which a vibration device including a vibrating exciter having an exciting coil attached thereto and a magnet facing the exciter at a predetermined interval is attached to a vibration panel. In the mounting structure according to claim 1, the vibrating panel includes a vibrating plate located above and a fixed plate located below the vibrating plate so as to face the vibrating plate. The magnets are respectively attached to the lower surface of the fixed plate via the magnet plates, and the magnet plates are formed so as to project downward from the lower surface of the vibration panel, so that the magnet plate can be used as a leg of the vibration panel. The vibration generated by the exciter of the vibration device is propagated to the vibration plate through the vibration plate,
Since it does not easily propagate to the magnet plate attached to the fixed plate, it has an advantage that a large vibration is not applied to the floor surface or the like by the magnet plate.
