A lead wire 50 is connected to the vibration effecting body A, that is, the exciting coil 47.

Further, the vibration effecting body A and the spring plate 48 are arranged such that a boss shaft portion 51 is provided in the center of the case 43, and the spring plate 48 The center of the spring plate 48 is fixed with a support rivet 52, and a vibration acting body A is attached to the outer side of the spring plate 48.
The inner part of the vibration effecting body A is attached with a rivet 53 so that it is concentric with the spring plate 48.
Further, 54 and 55 are rubber bushes, and 56 is an elasticity imparting window provided in the spring plate 48.

Furthermore, a cushion 57 made of sponge or the like is stretched over the surface of the permanent magnet 44 facing the vibration acting body A so that the vibration acting body A is not attracted to the permanent magnet 44 when the current is turned off. Further, on the surface of the case 43 facing the vibration effecting body A, a plurality of vent holes 58 are arranged at predetermined intervals in the circumferential direction to release heat generated in the coil. A filter 59 is stretched and closed. This vibrating device 40 is attached to a panel 61 of a mounting member 60, which will be described later, at a flange portion 43a of the case 43.

The mounting member 60 consists of a panel 61 made of foamed polyethylene and a backing plate 62 made of a synthetic resin with high hardness adhered to one side of the panel 61. The panel 61 has an opening in the center (opening 61a), and The plate 62 has a mounting hole 6 for the vibration device 40.
2a is provided, and the case component 4 of the vibrating device 40 is
1 of the case 43 is placed in the opening 61a of the panel 61.
It is installed on. The receiving member 70 is a horizontal piece 70
a, a vertical piece mounting piece 70b, and a support piece 70c that supports the horizontal piece 70a and the vertical piece 70b, the horizontal piece 70a is adhered to the lower surface of the upper part of the chassis 30, and the vertical piece 70b A panel 61 of a mounting member 60 of the vibrating device 40 is bonded to the top plate 21 of the vibrating device 40, and the periphery of the case 43 of the vibrating device 40 is oriented perpendicularly to the upper plate 21 of the stage body 20.

Further, the lead wire 50 is connected to the shear sea 30.
While connecting to the amplifier 80 attached to the
The amplifier 80 was attached to the chassis 30.
It is connected to an AC/DC converter 81 by a lead wire 82, and the AC/DC converter 81 is connected to a commercial power source (not shown) by a lead wire 83.
Note that 84 is a volume adjustment knob connected to the amplifier 80 by a lead wire 85.

Since the present invention is constructed as described above, by passing a current in the audio bass range through the lead wire 50, a magnetic repulsion/attraction action is generated between the excitation coil 47, that is, the vibration effecting body A, and the permanent magnet 44. As a result, the vibration effecting body A vibrates due to the elasticity of the spring plate 48, and vibration waves in the low frequency range are emitted. The vibration waves and the like are transmitted to the entire case 43, to the mounting member 60 that contacts the case 43, and further to the receiving member 7.
The vibration waves and the like are transmitted in the lateral direction of the upper plate 21 of the stage main body 20 through 0. Therefore, vibration waves of vertical movement are not directly transmitted to the feet of a human body standing on the stage body 20, and even if a person performs singing etc. on the stage body 20 for a long time, vomiting may occur. It doesn't cause any trouble.

Incidentally, in the above embodiment, the vertical piece 70 of the receiving member 70
As shown in FIG. 6, the chassis 30 has a horizontal piece 90a, an inclined piece attachment piece 90b extending at an acute angle from one end of the horizontal piece 90a, and the horizontal piece 90a and the inclined piece 90b. When a receiving member 90 consisting of a supporting piece 90c that supports the stage Main body 20
The vibration waves of vertical motion are not directly transmitted to the feet of the human body standing above. Further, in the above embodiment, the vibration device 40 emits vibration waves in the low frequency range, but it may also be a vibration device (speaker) that emits vibration waves in the audible frequency range, or a vibrating body that emits vibration waves in the low frequency range. The vibration device may also include a speaker that emits vibration waves of an audible frequency.

(Effect of the invention) As explained above, according to the invention, in a stage main body having an upper plate on which a person stands, there is a horizontal piece fixed to the lower surface of the upper plate, and a horizontal piece is attached to the upper plate from the horizontal piece. Since a receiving member consisting of a mounting piece extending downward and a mounting member for mounting the vibrating device opposite to the mounting piece are provided, the vibration waves of the vibrating device are transmitted to the upper plate through the mounting member and the receiving member. It propagates laterally. Therefore, the vibration waves of vertical motion are not directly transmitted to the feet of people standing on the stage body, and even if they sing on the stage body for a long time, it may cause vomiting. It has the advantage of not causing harmful effects on the human body.
